Do you know the 9 characteristics of the PC board?

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) Tiantian 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 steel”. "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.
