I believe many users know Shandong color coated board products. With the wide application of Shandong color coated board products, more and more users begin to pay attention to the composition and characteristics of products. Next, I believe you will know more about our products through our introduction.
The additive used in color coated board is a small amount of additive added to improve coating performance. The amount of additives in the coating is small, but the effect is remarkable. For example, some can improve the performance of coatings and films, some can shorten the drying time, and some can prevent the film from becoming ill. There are many kinds of additives, including desiccant, curing agent, leveling agent, defoamer, matting agent, stabilizer, etc.
Almost most liquid coatings are composed of some raw materials, the most important of which is resin, which is indispensable for any coating. It can be said that resins (sometimes containing solvents and additives) are transparent coatings, and then pigments are added to form coatings of various colors.
The process flow of color coated steel plate is as follows: color coated steel plate is a product based on cold-rolled steel plate and galvanized steel plate, which is prepared by surface pretreatment (degreasing, cleaning, chemical conversion), continuous coating (roll coating), baking and cooling. The common process flow of double coating double drying continuous color coating unit is as follows: uncoiling → pretreatment → coating → baking → post-treatment → coiling.
Shandong color coated board is light in weight, beautiful in appearance, good in corrosion resistance, and can be processed directly. It provides new raw materials for the construction industry, shipbuilding industry, automobile manufacturing industry, furniture industry and electrical industry, and has a good effect of replacing wood with steel, efficient construction, energy conservation and pollution prevention.
The color coated plate manufacturer specializes in producing color coated plates based on galvanized steel plates. In addition to zinc protection, the organic coating on the zinc layer plays a role of covering and isolation, which can effectively prevent the steel plate from rusting, and its service life is longer than that of galvanized steel plate. It is reported that the service life of color coated steel plate is 50% longer than that of galvanized steel plate. The service life of color coated plates with the same amount of zinc plating, the same coating and the same coating thickness will vary greatly in different regions and parts.
Buildings or plants made of color coated boards usually have a long service life under rain erosion. Otherwise, their use will be affected by the action of gas, salt and dust. Therefore, in the design, the greater the inclination of the roof, the less likely it is to accumulate dust and other dirt, and the longer its service life; Areas or parts that are not often washed by rain should be washed with water regularly.
