Comparison between the roof of the endurance plate and the glass roof
PC solid sheet before, the traditional lighting roof is made of glass, but now the PC solid sheet lighting is increasingly popular with builders. This change, mainly due to the advantages of PC solid sheet, complementary glass lighting deficiencies.
So, what is the difference between glass material and PC solid sheet quality? Which is better?
Glass roof of the shortage: easy rupture easy to fall off. The main reason:, fixed pieces of rust: used for fixing the roof of the steel components due to oxidative corrosion, resulting in mu fixed instability. , frame deformation: housing subsidence, temperature change, its own quality and service life, etc. may cause deformation of the frame, which leads to glass rupture and even fall off. , silicone Aging: adhesion of the roof of the silica gel will be aging over time, fatigue, and even failure. , the internal bubble: if the glass ceiling bubble inclusions (this type of bubble is often difficult to distinguish), after receiving the sun, the thermal effect uneven, easy to burst.
However, the PC solid sheet can better solve the above problems, complementary glass deficiencies. Mainly reflected in:, heat transfer: PC solid sheet heat transfer is lower than ordinary glass and other plastic thermal conductivity (k value), so that the loss of heat greatly reduced, for the building of warm equipment, environmental protection materials. , Impact Resistance: PC solid sheet is the best impact resistance in thermoplastic, the PC solid sheet made of polycarbonate can maintain good impact resistance for a long time in a fairly wide range of temperature, with "not Broken glass" and "ring Steel" laudatory name. , flame retardant, fire protection: PC solid sheet Fire resistance by the National Fire Building Materials Supervision Center test, according to gb--Standard, to reach the refractory B-class. The plate itself has a high ignition, the combustion process will not produce poisonous gas, will not encourage the spread of fire, from the burning out. No fire drop, non-toxic gas and other advantages, is the ideal lighting roofing materials.
