Caitu in the country has a large market, Boxing is color-coated, galvanized sheet distribution center, the following analytical about what color coating of color-coated market problems. Second, the lack of high-end products, the low-end products, excess capacity currently caitu grade domestic product is relatively low, high-quality, high-tech, high value-added products less, these products still can not meet the needs of the market, while the low-end general product capacity is large, there have been excesses. China's high-grade painted steel appliances caitu a promising market, but China is capable of producing high-grade painted steel manufacturers small, limited production, some products along genus gaps need to be developed. It should be said, the past few years, the domestic color coated steel plate has been greatly grow in capacity, variety, size and quality, particularly in the development of more rapid production of domestic low-level redundant construction and vicious competition in the market makes prepainted also makes a lot of investment of tens of millions of units put into discontinued. Caitu industry is a very promising industry. 3. precaution ?? in color coated color coated paper production process, color, coating edge thickness is not uncommon, but with increasing thickness of the coating, the coating edge thickening will become increasingly evident . For lead to thickening of the edge color coated paper various factors, many should take appropriate precautions to minimize the edge thickness to ensure that the product will not fall off the edge coating or paint chips in use locally, etc. undesirable phenomena. The main preventive measures are: 3.1 ?? reasonable grasp optimize the quality of raw materials 3.1.1 ?? ?? coating performance due to different levels of color coating production line is not exactly the same hardware configuration, coating properties of the coating process configuration should be based on the production line, painted case cover characteristics and the like used in the substrate adjustment formula. Mainly from the following means of leveling coatings, curing composite coating performance can be adjusted to reduce edge thickening. ?? ?? 1) Coatings leveling adjustment. ?? Leveling properties can be mixed solvent through the paint, and the ratio of rational use of chemical agents, leveling agents to adjust. And adjustment should be appropriate and necessary to ensure good coating leveling effect, but also to avoid the edge thickening. 2) Adjust the paint curing properties. 3) cooling intensity. a. Cooling water out of the water pressure is stable at 0.3MPa. ???? B. Out of the water temperature difference of control in 20.
