There are two kinds of hardening processes for PC board: surface coating process and surface coating process, both of which can achieve the hardening effect.

Hardening treatment of PC board: the surface of PC board is coated with some hardening coatings containing silicon, titanium and other components to increase the hardness. The surface of common PC endurance board substrate is electroplated or coated, and the hardening coating is attached to its surface, and then it is dried in the oven to meet the hardening requirements. The surface hardness of PC hardened plate treated by hardening process can reach about 3h--4h, which can meet the general industrial requirements. Common hardener chemicals include: composite metal oxides with titanium oxide as the main component and hydrolysates with silicon compounds.

PC sunshine board, referred to as PC board for short, is the trade title of polycarbonate board. It is a widely adopted building material with high strength, light transmission, sound insulation and energy saving. The solar panel also has the functions of light weight, weather resistance, flame retardancy and sound insulation, so it is recognized by construction planning, decoration engineering and environmental engineering.

Endurance board product features:

(1) Light transmittance: the light transmittance of PC sunlight plate can reach about 89%, which can be beautiful with glass. UV coated panels are not easy to produce yellowing when exposed to the sun. They are atomized and have poor light transmission. The loss of light transmission is about 10%, the loss rate of PVC is about 15-20%, and the loss rate of glass fiber is about 12-20%.

(2) Impact resistance: the impact strength is about 250-300 times that of ordinary glass, about 30 times that of acrylic plate with the same thickness, and about 2-20 times that of tempered glass. It has the reputation of "unbreakable glass" and "sound steel".

(3) Anti ultraviolet and external line: one side of PC board is coextruded with anti ultraviolet and external line (UV) coating, and the other side is treated with anti condensation, which integrates the functions of anti ultraviolet and external line, heat insulation and fog drop prevention. It can prevent the purple line from passing through, and is suitable for protecting valuable works of art and exhibits from being damaged by the purple line.

(4) Light weight: the proportion is about half of that of glass, saving the cost of transportation, removal, installation and support frame.

(5) Flame retardant: it is confirmed in the standard gb50222-95 that P C solar panels are flame retardant, i.e. Class B1. The ignition point of PC board is about 580 ℃, and it will self extinguish after leaving the fire. No * gas will be generated during combustion, which will not contribute to the spread of the fire.

(6) Bendability: the cold bending method can be adopted on the construction site according to the design drawing, and the arch, semi-circular roof and window can be installed. The bending radius is about 175 times of the thickness of the plate, and it can also be hot bent.

(7) Sound insulation: the sound insulation effect of PC solar panel is obvious, and it has sound insulation compared with glass and subassemblies of the same thickness. Under the condition of the same thickness, the sound insulation loss of PC solar panel is about 5-9db higher than that of glass. It is the material of choice for highway noise barrier.

(8) Energy saving: it is cool in summer and insulated in winter. The thermal conductivity (k value) of PC solar panel is lower than that of ordinary glass and other plastics. The thermal insulation effect is about 7-25% higher than that of the same glass, and the thermal insulation of PC solar panel is about 49%. Thus, the heat loss is greatly reduced, which is used in buildings with heating equipment.

(9) Temperature adaptability: PC board is not prone to cold embrittlement at -40 ℃ and does not change at 125 ℃. Its mechanical and mechanical properties do not change significantly in harsh environment.

(10) Weather resistance: the PC solar panel 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 reduction value of light transmittance is about 0.6%.

(11) Anti condensation: the outdoor temperature is 0 ℃, the indoor temperature is 23 ℃, the indoor relative humidity is less than 80%, and the inner surface of the material is free of condensation. Dew will flow away along the surface of the plate and will not drip.
