Variation of color-coated optical properties of the coating failure theory, color-coated optical properties of the worst loss of test points should be in Hainan, Hainan since the maximum intensity of ultraviolet radiation, radiation longest time, it will destroy the coating structure, resulting in degradation of the resin, the coating surface becomes rough, glossy fastest decline. But the actual test result is loss of light performance Baosteel test points are also poor. Baosteel analysis test point located in an industrial environment, the settlement of various large industrial pollutants, and industrial fallout Unlike dust, it has strong corrosion, the coating of color-coated strong ability to embed can not be cleared by the cleaning process, resulting in decreased gloss coating. At the same time due to industrial fallout are generally corrosive, corrosive coating embedded in the coating, causing damage Boxing color-coated resin structure will cause a decline in gloss. Within three years of the trial period, the impact is even greater than the ultraviolet degradation of the coating. Mechanical properties of color-coated from a structural point of rock wool composite panels, although as a support surface using color steel skeleton is filled with rock wool to make silver color coated, bonded together by glue and it has a certain carrying capacity, but its bending strength polystyrene sandwich composite panels much worse than the color steel surface, when used as a ceiling, more must be installed above the steel beam to compensate for the lack of its strength, however, when more than 2000mm or bend very easily deformation. Hollow Sandwich Glass magnesium composite board in the middle of the plate due to sandwich its plate glass magnesium body and keel are connected together, with the overall structure of high ancient itself has high strength, steel composite talk, its overall more has good bending, impact resistance, can be done relatively long length. However, due to the weight of large, generally should not exceed the length of 4m, require longer than 4m ceiling if installed safety measures. Third: waterproof wool sandwich Sandwich panel: color-coated wool with a strong water absorption, transport, storage, installation process, once wet, prone composite panels unglued, bulging, deformation, and the surface of the steel plate Long-term use in wet environments, causing steel corrosion. Magnesium hollow steel composite panel: As good moisture resistant magnesium plate glass, its wet and dry deformation rate, heat expansion size, are the other products can not match the specifications of color-coated, especially dry state flexural strength 15Mpa, moisture status under 22Mpa, namely strength to higher moisture condition, and never make a composite plate deformation.
