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 other 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 and adsorption Color roll off the lowest price, rolling oil and its accompanying suspension components will remain in the 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 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. Caitu skim a washing a surface adjustment (optional) a dry-chemical conversion film treatment early generally use a dry spray / dipping process. In addition to the third step of the process by dipping, the rest are chemicals applied by spray method. After treatment generally contains chromium, by processing only after removing excess residue membrane surface, but also form a compound layer of chromium on the surface, to improve the corrosion resistance of the coil. When aluminum coil material application, a film weight 30 6 5 mg / m Z. Most of the post-treatment process is also used chromium compounds. After a good deal of chemicals to control the composition and operating conditions to make the amount of chromium conversion coatings containing uniform. Theodolite target board to find out through a standard horizontal, vertical centerline of the base and pull wire baseline, which is also the uncoiler, coiler equipment horizontal, vertical centerline. Separation is a physical treatment, is separated by physical action, recycling waste water insoluble contaminants in suspension (film and oil droplets) method Shandong color steel manufacturers, can be divided into gravity separation, centrifugal separation and retention sieve method. Activated carbon adsorption is physical chemical treatment. Adsorption is an interface phenomenon Shandong Boxing Color volume factory, which play a role in Color Volume Two phases of the interface, for example, activated carbon in contact with wastewater, wastewater contaminants will be transferred from the water to the surface of activated carbon on This is the activated carbon adsorption. Color Color Volume lowest price volume _ _ Shijiazhuang Steel Jinhong Run by Boxing Xingfu Town 金宏润 Steel Industry and Trade Ministry.
