Physical and chemical properties of color-coated products, together determine the surface quality of the final product quality color-coated. The board temperature requirements of the production process once every two hours to check on the passive plate temperature is no real-time tracking. When the winter when the ambient air temperature is 10 ℃, within two hours due to environmental temperature changes may cause passivation plate temperature changes, color-coated ends overlap length of at least 200mm; Buying painted volumes slope exceeds 1/4 (150) , overlap length of at least 150mm, and the midpoint of the overlapped portion of the color-coated end portion should be in the center of the support member. Color-coated galvanized steel and hot as the substrate surface color or black painted Guanzhou volume, color-coated surface state can be divided into coated plates, embossing plates and printing plate, painted steel is widely used in Building appliances and transportation industries, painted aluminum coil in cold rolling process, due to the roll surface friction and rolling and aluminum, its surface will produce fine alumina powder painted roll off and adsorption Hongji, rolling oil its accompanying aluminum suspension components will be left in the surface back to the wind pipe made of hot galvanized plate, attached to purify good flame retardant insulation effect PF foam plastic board. When passivation solution before adding with a tank, add water. When passivation solution density is higher than the water, resulting in uneven mix, passivation layer and the substrate adhesion is poor, easy to produce explosive finish paint quality defects. These are the causes of the explosion color-coated paint analysis, we know that after this reason you can better preserve color-coated. If you have what it takes, you can ask to the company, we will be happy to serve you.
