Have you heard of the PC board? This is a new type of high-strength, heat-insulating, light-transparent, lightweight building materials, including transparent, blue, green, milky white, brown, etc., mainly used in lighting canopies, road noise barriers, stadiums ( Pavilion) Skylights, street signs, light box advertisements, telephone booths, waiting (machine) pavilions, garden amusement park ceilings, agricultural planting, aquaculture light sheds, home balconies and other fields. Its main features are:
(1) Transmittance
The PC board has a light transmittance of up to 89%, which is comparable to glass. UV-coated panels do not produce yellowing under sunlight, and fogging, poor light transmission, after 10 years, the loss of light transmission is only 6%, the rate of PVC loss is as high as 15%-20%, and the fiberglass is 12 %-20%.
(2) Anti-impact
The impact strength is 250-300 times that of ordinary glass, 30 times of acrylic glass of the same thickness, 2-20 times of tempered glass, and there are no cracks when falling 2 meters below 3kg hammer. There are “not broken glass†and “sound steelâ€. "The name of the."
(3) UV protection
The PC board is coated with an anti-ultraviolet (UV) coating on one side and anti-condensation treatment on the other side, which combines UV protection, heat insulation and dew condensation. It blocks UV rays and protects valuable artwork and exhibits from UV damage.
(4) Light weight
The specific gravity is only half that of glass, saving the cost of transportation, handling, installation and support frames.
(5) Flame retardant
The national standard GB50222-95 confirms that the PC board is a non-flammable level, that is, B1 level. PC board's own ignition point is 580 degrees Celsius, self-extinguishing from the fire, no toxic gas will be produced when burning, it will not promote the spread of fire.
(6) bendability
It can be installed in an arched, semi-circular top and window on the site according to the design. The minimum bending radius is 175 times the thickness of the plate, and it can also be bent.
(7) Sound insulation
The PC board has obvious sound insulation effect, and has better acoustic insulation than the glass and the sub-force board of the same thickness. Under the same thickness condition, the sound insulation of the PC board is increased by 3-4 DB than the glass. Internationally the material of choice for highway noise barriers.
(8) Energy saving
In summer, it is cool, and the winter is insulated. The PC board has a lower thermal conductivity (K value) than ordinary glass and other plastics. The heat insulation effect is 7%-25% higher than that of the equivalent glass, and the insulation of the PC board is up to 49%. Therefore, the heat loss is greatly reduced, and the building used for the heating equipment is an environmentally friendly material.
(9) Temperature adaptability
The PC board does not undergo cold brittleness at -100 ° C, does not soften at 135 ° C, and has no significant change in mechanical and mechanical properties in a harsh environment.

The purpose of using fabric sandwiched rubber sealing material is to increase the stiffness and strength of the sealing ring, prevent rubber extrusion, and make it suitable for high pressure. At the same time, in the process of wear, rubber wears ahead of fabric. When the rubber of the parts with high contact pressure wears off, the wear extends to the parts with low contact pressure, so that the wear of the whole sealing surface tends to be uniform, but the friction does not change significantly. However, the lip of the rubber sealing ring sandwiched with fabric can easily scrape off the oil film on the sliding surface, so the lubricity is worse than that of leather and polytetrafluoroethylene.
