What is polycarbonate: features, technical characteristics and specifics of choosing the appropriate material. Polycarbonate - what kind of material is it and where is it used? Moisture resistance

Polycarbonate is a colorless, hard polymer plastic. In production it is used in the form of granules. It is distinguished by its lightness, high strength, transparency, ductility, frost resistance and durability.

Also this material is a good dielectric. From a chemical point of view, polycarbonates are synthetic polymers.

The special properties of polycarbonate are achieved due to the unique structure of its macromolecules. Since polycarbonate is a thermoplastic (thermoplastic polymer), when hardened it is able to restore its properties.

It is worth noting that such material can be subjected to repeated recycling, which makes it environmentally attractive. Polycarbonate is made from polycarbonate granules using the extrusion principle. The applied UV protective layer has reliable protection from direct sunlight.

Polycarbonate sheets are very popular for devices due to their unique performance properties, as well as a wide range of applications. The main advantages of polycarbonate include:

• ease;
• transparency;
• simple installation;
• strength;
• flexibility;
• ease of processing;
• resistance to negative impacts environment and chemical elements;
• sound and heat insulation;
• safety.

Polycarbonate can be cellular or monolithic. Cellular polycarbonate is widely used in construction, as it is quite lightweight, but at the same time durable material. Sufficient ductility and high impact resistance make it possible to obtain products with thin walls without losing their basic properties.

Monolithic polycarbonate is considered less common. It is a solid plate that is used for cladding various construction projects. The products are strong enough to withstand various impacts and eliminate the need to use a metal frame.

Due to their flexibility, polycarbonate sheets are an ideal material for covering even the most geometrically complex structures. Installation of polycarbonate plates will not be difficult. Comfortable polycarbonate profiles are used, which have the same color range and mechanical properties. The sheets lend themselves perfectly to processing with ordinary cutting tools.

Polycarbonate granules are the main raw material for the manufacture of PC sheets. Polymer sheet is widely used in the production of lighting products, clutch parts, mechanical engineering parts and electrical parts.

Also, it is impossible to do without the use of polycarbonate in construction, furniture production, manufacturing of weapons, protective equipment and sporting goods, storage media, etc. Very often, polycarbonate is used as a glass substitute. Summer residents use this material for equipment and greenhouses.

Polycarbonate has high strength and maybe varying degrees transparency and various colors. Polycarbonate products are characterized by a high degree of fire safety. When a polymer is exposed to fire, it does not burn, but melts, without releasing toxic substances.

Is completely environmentally friendly pure material. It is created on the basis of carbonic acid salts, which are incapable of causing harm. environment. When interacting with fire, heavy metal fumes and other vapors are not released into the air harmful substances. The safety of the polymer is explained by the fact that it is used in industries such as medicine and the food industry.

Polymer materials today are widely used in the construction of buildings and structures for various purposes. Among them, polycarbonate is a panel that consists of two or three layers, between which there are longitudinally oriented stiffeners. Due to the cellular structure, it was possible to achieve mechanical strength of the canvas with low weight.

Description of polycarbonate

Cellular polycarbonate in cross section resembles a honeycomb, which can be triangular or rectangular in shape. The raw material for this material is granulated polycarbonate, which can be obtained by condensation of dihydroxyl compounds and polyesters of carbonic acid. The material is produced in accordance with TU-2256-001-54141872-2006, however, the dimensions specified in these rules may vary depending on the wishes of the customer. The parameters are determined by the manufacturer; the maximum permissible deviation is not set.

Temperature conditions of use

Cellular polycarbonate is highly resistant to adverse environmental conditions. use depends on the brand of material, compliance with the rules of technology and the quality of raw materials. For most types of panels, this indicator varies from -40 to +130 degrees. Some types of the described material can withstand extremely low temperatures, which are equal to -100 degrees. In this case, the structure is not destroyed. When exposed to high temperature or cooling, changes in linear dimensions may occur. The permissible expansion should not be more than 3 millimeters per 1 meter, regarding the width and length of the sheet. Due to the large nature of the polycarbonate material, it must be installed with appropriate clearances.

Chemical resistance

When using finishing panels, it is necessary to take into account the fact that they are exposed to all sorts of destructive factors. Polycarbonate is a material that has excellent resistance to a number of chemicals. However, it is not recommended to use sheets if they may be exposed to insecticidal aerosols, cement mixtures, PVC-plasticized substances, concrete, strong detergents, halogen and aromatic solvents, sealants based on ammonia, acetic acid and alkali, ethyl alcohol solutions.

Resistance of polycarbonate to chemical compounds

Polycarbonate is the material that will withstand impact saline solutions with a neutral acid reaction, as well as concentrated mineral acids. The panels are not afraid of reducing agents and oxidizing agents, as well as alcohol solutions, with methanol being an exception. When installing canvases, you must use silicone sealants and sealing elements specially produced for them.

Mechanical strength

Polycarbonate can withstand significant mechanical loads. It is necessary to take into account that the surface may be subject to abrasive effects during prolonged contact with small elements such as sand. In this case, scratches may form when exposed to rough materials that have sufficient hardness. Mechanical strength will depend on the structure and brand. If we talk about tensile strength, then a premium product has a parameter equal to 60 MPa. for the same brand it is 70 MPa. is 65 kJ/mm. The manufacturer provides a guarantee for preservation performance qualities for 10 years, provided that the sheets were installed correctly and using special fasteners.

Thickness parameters and specific gravity

The technology involves the possibility of producing polycarbonate different sizes. Currently, on the building materials market you can find sheets whose thickness varies from 4 to 25 millimeters. Each of these types has a different internal structure. The density of polycarbonate is 1.2 kilograms per cubic meter. For canvases, this indicator depends on the number of layers, the thickness of the panels and the distance between the stiffeners. With a sheet thickness of 4 millimeters, the number of walls is limited to two, while the distance between the stiffeners is 6 millimeters. With a thickness of 25 millimeters, the number of walls is 5, while the pitch between the ribs is 20.

Sun resistance

Polycarbonate is a material that can guarantee reliable protection against radiation. In order to achieve a similar effect, a layer of stabilizing coating is applied to the sheet during the production process. This technology ensures a service life of 10 years. Probabilities of detachment protective coating no from the material itself, since the polymer is reliably fused to the base. When installing the sheet, it is necessary to take into account the fact that the coating intended to protect against solar radiation must face outward. Light transmittance depends on color, for example, unpainted sheets have this indicator ranging from 83 to 90 percent. Transparent colored canvases transmit no more than 65 percent, but the transmitted light is well scattered.

Thermal insulation characteristics

When building a polycarbonate greenhouse, you should find out in advance what kind of material it is. It has excellent thermal insulation qualities. The thermal resistance of this material is achieved due to the air contained inside and because the fabric has significant thermal resistance. The heat transfer coefficient will depend on the structure and thickness of the sheet. This parameter varies from 4.1 to 1.4 W/(m² K). The first figure is correct for a sheet whose thickness is 4 millimeters, while the second figure is presented for a 32 mm sheet. Polycarbonate is a plastic whose use is advisable when it is necessary to combine excellent thermal insulation qualities and high transparency.

Fire resistance

Polycarbonate is considered resistant to high temperatures, it belongs to category B1, which according to the European classification designates a highly flammable and self-extinguishing material. When burned, it does not emit toxic gases and is not dangerous to humans. With the described thermal effect, which also applies to an open flame, the processes of formation begin through holes and structural destruction. The material begins to shrink in area.

Service life

This is the material whose manufacturers guarantee the preservation of the quality characteristics of the material for 10 years. This is true if the installation and operation rules are followed. If you prevent damage to the outer surface, you can extend the life of the panel. Otherwise, premature destruction of the canvas will occur. In areas where there is a risk of mechanical damage, it is necessary to use sheets whose thickness is 16 millimeters or more. During installation, it is necessary to take into account the exclusion of the possibility of contact with substances that can cause harm in the form of destruction.

Noise insulation characteristics

The honeycomb structure provides very low acoustic permeability, which indicates that the panels have excellent sound-absorbing properties, which depend on the type of sheet and its internal structure. Thus, if we're talking about For multilayer cellular polycarbonate, the thickness of which is 16 millimeters or more, the attenuation of the sound wave occurs in the range from 10 to 21 dB.

Conclusion

We can say that plexiglass is polycarbonate with less outstanding quality characteristics. The second type of material has higher strength and reliability; for these and many other quality characteristics, the honeycomb structure is chosen much more often. This is also due to the fact that polycarbonate is used in many areas, including construction and repair. Private consumers choose it to create canopies, greenhouses, gazebos and much more. The structures made from it are lightweight and do not require the construction of a special foundation. This reduces the cost of the process and simplifies the work.

The appearance of polycarbonate in the list of roofing materials has made a real revolution in the construction of small architectural forms: canopies, canopies, greenhouses, winter gardens, etc. A variety of choices, a wide color range, various physical parameters, and manufacturability enable architects to create unique projects. But the duration of their operation is greatly influenced by the correct choice of a specific type. roofing material in every case.

Before you take final decision, you should briefly familiarize yourself with the types of coatings and the physical differences between them.

We won't stop there strengths this coating, they are known to everyone thanks to the powerful advertising campaign of the manufacturers. Weaknesses materials are not familiar to all consumers, but they play an important role in the operational characteristics of structures. When choosing the type of roof, you need to know the objective parameters; only this will make it possible to make the right decisions.

This material can be seen on awnings most often, and deservedly so. It differs from monolithic in its more complex structure, consisting of several thin monolithic sheets connected to each other by partitions (honeycombs). The partitions act as stiffeners and significantly increase the mechanical properties of polycarbonate. Honeycombs have different geometric shape And linear dimensions, the thickness of the layers also changes slightly.

Another feature of cellular polycarbonate is that there are types of material that have several horizontal rows of honeycombs.

Types of cellular polycarbonate

Depending on the structural structure, the following types of cellular polycarbonate are available.

GOST R 56712-2015. Multilayer polycarbonate panels

A few words about chemical and physical stability. The material reacts negatively to methyl solutions, halogen chemical compounds, ammonia, alkalis, acetic acid. Tensile strength 62 MPa, impact strength 40 kJ/mm. These data refer to the budget, most used polycarbonate type 2H. The coating can be used in the temperature range from -35°C to +125°C.

For canopy coverings, the parameters of thermal conductivity and sound insulation do not matter; you do not need to pay attention to them when choosing. But it is recommended to look at fire resistance. In terms of flammability, polycarbonate belongs to group B1; the sheets are difficult to ignite and do not support independent open combustion. But this is a rather dangerous building material from a fire safety point of view.

Durability, subject to the instructions for use recommended by the manufacturer, is up to 15 years. The service life largely depends on specific conditions. If the canopy is on open area in the southern regions of our country, then under such conditions it is exposed to ultraviolet rays of maximum intensity. Accordingly, this cannot but have a negative impact on the service life of polycarbonate.

The mechanical strength and cost of the material depend on the thickness. It is recommended to choose individual material for each canopy design.

1. Small canopies, canopies, greenhouses, structures with a relatively small bending radius - sheet thickness 4mm. The cheapest material for universal use.
2. Terraces, canopies over swimming pools and playgrounds - sheet thickness 6–8mm.
3. Large durable canopies that are likely to accumulate a significant amount of snow - sheet thickness is 10 mm.

Prices for cellular polycarbonate

Monolithic polycarbonate

The thickness of the sheets is 2–12 mm, the material is much stronger and more expensive than cellular. As for weight, it does not affect the choice of a specific coating. Weight square meter approximately 7 kg, but this is not a problem for any canopy design. You need to know that during the calculation rafter system snow and wind loads are 250 kg/m2, based on such efforts the cross-section of the load-bearing elements is determined architectural elements. Seven kilograms can be completely ignored during calculations.

Currently, monolithic polycarbonate is produced in the following types:

• sheets with increased viscosity - PC-1;
• sheets with medium viscosity - PC-2;
• sheets with low viscosity - PC-3;
• heat-stabilized – PC-4;
• highly resistant to microcracks, fire resistant – PK-M-2;
• with increased mechanical strength and the addition of quartz sand - PK-LSV-30.

When choosing a monolithic polycarbonate coating, you need to keep in mind the bending radius

Profiled polycarbonate

Physical and performance characteristics the same as that of a monolithic one. The coating differs only in thickness (0.8–1.5 mm) and the presence of a geometric profile. The bending strength depends on the height of the profile; this value ranges from 10–50 mm. Wave pitch 40–90 mm.

Prices for different types of square pipes

When designing a canopy, you need to take into account a number of features of polycarbonate; this will reduce the amount of unproductive waste and increase the reliability and durability of the coating.

For connection and fastening, use special profiles; they are sold complete with coatings.

1. Wall profile. Performs two tasks simultaneously: seals the panels and fixes them to vertical walls or other elements.

   

2. Connecting profile. It is not fixed to the structure and is used to connect two sheets along the honeycomb direction. It can be simple, non-separable or composite. The first requires significant physical effort when connecting the panels; to facilitate the operation, it is recommended to use a special device. The advantage is high reliability of the connection; it is recommended to use it on arched canopies. The composite connecting profile can be disassembled, which greatly simplifies the process. But in terms of reliability it is much inferior to the first; this profile can only be used on flat canopies.

   

3. Used to connect two sheets of panels placed at an angle of 90°. It is used on complex canopies with various canopies or special decorative elements.

   

4. End profile. Seals cut edges of panels along the honeycomb. Slides onto the sheet and is held in place by slight tension.

   

5. Used on sheds with gable roofs. It is made of soft plastic, which allows you to adjust the position of the elements depending on the angle of inclination of the slopes.

   

Before purchasing material, you need to accurately calculate the required quantity and decide on the range of profiles. It is recommended to buy them with a reserve; the profiles are sold in standard lengths.

The standard profile lengths are 3 and 6 meters; products with lengths of 4 m and 2.1 m can also be found on sale

Fastening polycarbonate is done with special hardware; it is not recommended to use ordinary self-tapping screws.

The fact is that plastic has a high coefficient of thermal expansion; only special hardware can compensate for it. Without such compensation, the roof will swell or come off, in both cases complex repairs will have to be made. In addition, it will no longer be possible to restore the original tightness of the canopy. Special thermal washers have a leg to prevent over-tightening; the length of the leg depends on the thickness of the sheets. The plug and cap with gasket guarantee the tightness of the connection and compensate for thermal expansion.

Important. A protective film is glued to the front side of the sheets, preventing UV rays from penetrating the polycarbonate. The manufacturer's logo is applied to it; this side must be the front side.

Protective films are removed immediately before installation of the roof. If the panels remain with protective films, it will be very difficult to remove them later.

Sheets are being cut electric jigsaw, an ordinary hacksaw with fine teeth or a grinder with a stone for metal.

Honeycombs must be sealed. The upper edge is sealed with a continuous film, and the lower edge with small holes. Small holes remove accumulated condensation. To improve water drainage, it is necessary to drill holes Ø 5–6 mm in the lower plastic profile.

If the panels are mounted on metal canopies, then it is recommended to install heat-insulating tape at the junction. It prevents local swelling due to heating of the material by the metal.

Polycarbonate can be used to create various architectural forms. All of them are beautiful appearance and fit perfectly into the existing landscape design personal plot. How to cover a terrace with transparent polycarbonate.

Cellular, or otherwise structured or cellular polycarbonate, got its name because of the special internal structure: its design can be two, three or four layers, filled with a certain number of stiffeners, forming triangles, crosses or squares. Looking at the leaf in cross-section, you can notice its resemblance to a honeycomb. Thanks to this structure, the material has excellent strength characteristics and a high coefficient of flexibility, and the air contained in the honeycomb provides its heat-saving properties.

Cellular polycarbonate - how it is made

For the manufacture of honeycomb material, polycarbonate is used - a granular colorless plastic mass, characterized by lightness, frost resistance, dielectric properties, and durability. The unique structure of polycarbonate macromolecules is the main reason for the unique properties inherent in it.

The thermoplasticity of the material allows it to recover during the solidification process after each melting process, i.e. the material can be recycled many times, which is very important from an environmental point of view.

The production of the material is carried out by extrusion, i.e. pressing the melted liquid viscous substance through the forming tool. The result is a canvas having a given cross-sectional shape.

Properties and advantages of honeycomb material

You can immediately notice that polycarbonate compares favorably with any transparent building material- none of them have similar positive qualities in full.

Cellular polycarbonate is different:

1. Low coefficient of thermal conductivity, providing higher heat-saving qualities of the material than glass, which allows you to reduce energy consumption for heating or cooling rooms by almost half.
2. The multilayer structure of the material provides good sound absorption and, accordingly, good sound insulation qualities.
3. The material scatters light rays well, its transparency is 86%, and does not cast a shadow when light passes through.
4. The material can be used at temperatures from -40 C to +120 C, i.e. it can be used in almost any natural area, quality characteristics materials depend very little on changes occurring in the environment. It is not susceptible to chemical reagents.
5. Polycarbonate has a low weight, approximately 16 times less than window glass and 6 times less than an acrylic sheet of the same thickness; the use of the material allows you to save money by designing a less powerful foundation and reducing construction costs supporting structures. Installation work can be performed without the use of special construction equipment.
6. The material has high viscosity, which ensures its impact resistance (200 times greater than that of sheet glass), and it is resistant to bending and tearing loads. In case of damage due to a very strong impact, sharp fragments will not form. The polycarbonate coating can withstand the loads exerted by accumulated snow and does not tear from gusts of wind, like polyethylene film what makes it ideal option for covering greenhouses. The good flexibility of the material allows it to be used when installing roof structures with complex geometry, including arched and vaulted.
7. Polycarbonate is not flammable; it does not burn, but under the influence of an open flame it melts to form a web-like fiber, without releasing toxic substances.
8. The constancy of the technical characteristics of the material is ensured by a protective layer applied to the front side of the sheets, which blocks the ultraviolet part of the solar spectrum.

Cellular polycarbonate - sheet dimensions and area of ​​application depending on thickness

Cellular polycarbonate is produced in a wide range color scheme, its base colors:

• warm - red, brown, bronze, orange, yellow, milky,
• cold - white, blue, turquoise, green,
• You can also find transparent panels.

If we talk about sheet sizes, it should be noted that polycarbonate is produced in several versions:

• monolithic, thickness from 2 to 12 mm, with standard dimensions sheet 2.05x3.05 m,
• cellular, thickness from 4 to 32 mm, with sheet dimensions 2.1 x 6 m or 2.1 x 12 m,
• profiled, 1.2 mm thick, sheet size 1.26x2.24 m, profile height up to 5 cm.

Depending on the thickness of the sheets, cellular polycarbonate can have different uses; it is recommended to use it in the construction of:

• 4 mm - canopies and greenhouses, showcases, exhibition stands,
• 6 mm - canopies, greenhouses, canopies,
• 8 mm - greenhouses, roofs, canopies, partitions,
• 10 mm - continuous glazing of horizontal and vertical surfaces, production of noise barriers, canopies,
• 16 mm - roofs over large structures,
• 32 mm - for roofs with increased load requirements.

Based on such a wide range of products, before starting construction, you will need to study the properties and decide which polycarbonate is rational to use in each specific structure.

Basic principles of working with polycarbonate

Since the sheets of material have quite large dimensions during construction, it will be necessary to give them required sizes, i.e. cut. Special problems There is no problem with cutting polycarbonate; if the sheet thickness is from 0.4 to 10 mm, then you can use a sharp retractable construction knife. It is not recommended to remove the protective film from the surface - it will provide protection from scratches.

The cut should be made carefully, ensuring an accurate, straight line. To cut thicker material, use a fence saw running at high speed. The teeth of such a saw should be made of reinforced alloys, small, undone. You can also use a jigsaw.

During operation, the sheet should be supported to prevent vibration. Chips that fall inside the sheet during cutting must be removed at the end of the work.

To attach polycarbonate, you will need to drill holes in the sheets. For this, sharp steel drills are used. It is necessary to mark the place for drilling so that it is located between the internal stiffeners. The distance from the hole to the edge should be about 10 mm.

You can bend cellular polycarbonate exclusively along the channel lines, along the length of the sheet. The bending radius can exceed the sheet thickness by 175 times.

Since there are voids inside the sheets, special attention should be paid to processing their end part. If the sheets will be mounted in a vertical or inclined position, then the ends should be covered in the upper part with a self-adhesive aluminum strip, and in the lower part with a perforated strip, which can protect the material from penetration of dirt, but allows condensation to drain.

When using polycarbonate in the construction of an arched structure, it will be necessary to cover its ends with perforated film. Materials for sealing should be selected that match the colors of the panels.

• Aluminum sealants are considered to be of the highest quality; they are durable and easy to use.
• When using non-perforated sealant, holes of the smallest diameter should be drilled in it to allow condensate and vapors to escape.
• It is not recommended to leave the ends open - this will reduce the transparency of the panels and reduce their service life.
• It is not recommended to seal the ends with regular tape.
• When installing the sheets, they should be oriented in such a way as to ensure unhindered drainage of condensate.
• The installation of panels should be planned in such a way that when vertical installation The stiffening ribs were located vertically, when constructing a pitched surface - longitudinally, for an arched surface - in an arcuate manner.
• For outdoor work, use a material with a layer that protects it from ultraviolet radiation.

Polycarbonate fastening

Load-bearing longitudinal supports for the frame are mounted in increments:

• for 6-16 mm sheets - 700 mm,
• for 25 m sheets - 1050 mm.

When calculating the distance between transverse supports, the following are taken into account:

• expected wind or snow loads,
• angle of inclination of the structure.

The distance can be from 0.5 to 2 m.

To fasten polycarbonate, self-tapping bolts or thermal washers are used, one of which is a plastic plate with a high rod, the other is a seal, and a snap-on lid is also included. The thermal washer ensures a strong and tight connection without cold bridges and compression of the panels. To avoid problems caused by thermal expansion, the holes should have a diameter larger than the cross-section of the washer leg by a couple of millimeters.

Nails or rivets must not be used to secure panels! It is not recommended to overtighten self-tapping bolts during installation. Incorrect fastening of polycarbonate with self-tapping screws can lead to a reduction in its service life.

If one-piece panels are being installed, then they should be inserted into the profile rebate of the same thickness as these panels.

Using self-tapping bolts they are attached to the longitudinal support. Before starting work, it is recommended to condition the sheets cellular polycarbonate in a dry, warm room, and only then seal their ends with self-adhesive tape - in this case, condensation will not form inside the cellular material. To prevent the possibility of damage to the surface when snapping the profile, use a wooden mallet.

During installation, it should be taken into account that polycarbonate is not classified as a static material; its dimensions, albeit to a small extent (up to 0.065 mm/m with a temperature change of 1 degree), but change due to temperature changes. Therefore, during installation, appropriate gaps should be left, but we should not forget about the need to use special fasteners that will prevent the panels from slipping out when the temperature drops. It is enough that the free play reserve is 2 mm for each linear meter. The diameters of the holes prepared for fastening must meet the above requirements.

Operation and care of polycarbonate surfaces

1. Before installation, the panels should be stored in packaged form and transported in a horizontal position.
2. It is not recommended to store panels in direct sunlight or rain.
3. You cannot walk on polycarbonate sheets.
4. The panels are cleaned with a soft cloth moistened with a solution of soap or dishwashing detergent.
5. Do not use detergents that contain ammonia, acids, chlorine, solvents, or salts.
6. Do not use sharp objects to remove dirt - they can scratch the ultraviolet protective layer.
7. The sheets are installed in such a way that the side on which the protective film is applied faces outwards. You should find the UV protection designation on the packaging.
