What are the advantages of PC board?

1. light transmittance: the maximum light transmittance of printed circuit board can reach 92%, which is equivalent to that of glass. UV coated board will not turn yellow, fog and have poor light transmission in the sun, and the light transmission loss is only 6% after ten years. .

2. Impact resistance: the impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic board with the same thickness and 2-20 times that of tempered glass. Even with a hammer weighing less than two meters and weighing 3 kilograms, it also has the reputation of "unbreakable glass" and "ringing steel".

3. Anti-ultraviolet: One side of PC board is coated with anti-ultraviolet (UV) coating, and the other side is treated with anti-condensation, which integrates the functions of anti-ultraviolet, heat insulation and anti-dripping. It can block the passage of ultraviolet rays and is suitable for protecting valuable works of art and exhibits from ultraviolet rays.

4. Light weight: the specific gravity is only half that of glass, which saves the cost of transportation, unloading, installation and support of the frame.

5. Flame retardant: GB 50222-95 confirms that PC board is flame retardant, that is, B 1. The ignition point of the PC board itself is 580 degrees Celsius, which will go out by itself after leaving the fire source, and will not produce toxic gas when burning, which will not promote the spread of the fire.

6. Flexibility: cold bending can be used on site according to the design drawings, and it can be installed into arched and semi-circular roofs and windows. The minimum bending radius is 175 times of the thickness of the adopted plate, and it can also be hot bent.

7. Sound insulation: PC board has obvious sound insulation effect, which is better than glass and secondary stiffeners with the same thickness. At the same thickness, the sound insulation of PC board is 3-4 dB higher than that of glass. It is the first choice material for road noise barrier in the world. ?

8. Energy saving: cool in summer and warm in winter. The thermal conductivity (K value) of PC board is lower than that of ordinary glass and other plastics, and the thermal insulation effect is better than that of the same building. 9. Temperature adaptability: PC board will not be cold brittle at-100℃, will not soften at 135℃, and its mechanical properties will be zero in harsh environment.

9. Weathering resistance: PC board can maintain the stability of various physical indexes in the range of -40℃ to 120℃. After 4000 hours of artificial climate aging test, the yellowing degree is 2, and the decrease of light transmittance is only 0.6%. 1 1. Dew prevention: When the outdoor temperature is 0℃, the indoor temperature is 23℃, and the indoor relative humidity is lower than 80%, the inner surface of the material will not be dewed.
