6-layer hollow daylighting board

Performance and features

(1) Light transmittance: The light transmittance of PC board can reach up to 89%, which can match the beauty of glass. UV coated panels will not produce yellowing, atomization, or poor light transmission when exposed to sunlight. After ten years, the light transmission loss is only 6%. The PVC loss rate is as high as 15%-20%, and the glass fiber is 12%. %-20%.

(2) Impact resistance: The impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic plates of the same thickness, and 2-20 times that of tempered glass. There will be no cracks when dropped two meters below with a 3kg hammer, and it is "not broken" It has the reputation of "glass" and "ringing steel".

(3) Anti-ultraviolet: One side of the PC board is coated with an anti-ultraviolet (UV) coating, and the other side has anti-condensation treatment, integrating the functions of anti-ultraviolet, heat insulation and anti-drip. It can block the passage of ultraviolet rays and is suitable for protecting valuable artworks and exhibits from ultraviolet damage.

(4) Light weight: The specific gravity is only half that of glass, saving the cost of transportation, handling, installation and supporting frames.

(5) Flame retardant: The national standard GB50222-95 confirms that PC boards are flame retardant to the first level, that is, B1 level. The PC board's own ignition point is 580 degrees Celsius. It will self-extinguish after being removed from the fire. It will not produce toxic gases when burning and will not contribute to the spread of the fire.

(6) Flexibility: It can be cold-bent at the construction site according to the design drawings, and installed into arches, semi-circular roofs and windows. The minimum bending radius is 175 times the thickness of the plate used, and hot bending is also possible.

(7) Sound insulation: PC board has obvious sound insulation effect and has better sound insulation than glass and acrylic boards of the same thickness. Under the same thickness, the sound insulation of PC board is 3-4DB higher than that of glass. Internationally, it is the preferred material for highway noise barriers.

(8) Energy saving: Keep cool in summer and keep warm in winter. PC board has a lower thermal conductivity (K value) than ordinary glass and other plastics, and the thermal insulation effect is 7%-25% higher than the same glass. The insulation effect of PC board Heat up to 49%. As a result, heat loss is greatly reduced, and it is an environmentally friendly material used in buildings with heating equipment.

(9) Temperature adaptability: PC boards do not become cold brittle at -100 degrees Celsius, do not soften at 135 degrees Celsius, and have no significant changes in their mechanics and mechanical properties in harsh environments.

(10) Weather resistance: PC boards can maintain the stability of various physical indicators in the range of -40°C to 120°C. After 4,000 hours of artificial climate aging test, the yellowing degree was 2 and the light transmittance reduction was only 0.6%.

(11) Anti-condensation: When the outdoor temperature is 0°C, the indoor temperature is 23°C, and the indoor relative humidity is lower than 80%, there will be no condensation on the inner surface of the material.
