Color-coated galvanized steel and hot as the surface of the substrate color or black, the surface state of the coating can be divided into color-coated plate, embossed plates and printing plate, painted steel appliances widely used in construction and transportation Which color steel and other industries, painted aluminum coil in the cold rolling process, due to the roll surface friction and rolling and aluminum, its surface will produce fine alumina powder off and adsorption, rolling oil and its accompanying suspension components will be left in aluminum surface, return air duct 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 color-coated coil Color Explosion Causes paint lowest price, we know that after this reason you can better preserve color-coated. If you have what it takes, you can ask the company to Shandong color steel manufacturers, we will be happy to serve you. Color-coated, for example, in industrial areas or coastal areas, due to air in the role of sulfur dioxide gas or salt by corrosion speed, life is affected. Color volume during the rainy season, long coat soaked by rain or dew in the day and night temperature difference is too easy site will quickly corrode, life will be reduced. Color coated steel manufacturing buildings or factories, often subject to a longer life when rain washed. Therefore, in the design, if the inclination of the roof of the larger, less likely to accumulate dust and dirt, longer service life; for those parts of the region or not rain often wash, rinse with water regularly. 3, uses color-coated steel: construction (outdoor) plant, agricultural warehouse, residential precast, corrugated roofs, and household appliances.
