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. First, the color plate production capacity in recent years, the rapid expansion of China's color coated production history is not long, but a few years the pace of development is very alarming. Back in 1995, the production of painted steel China has only 12 million tons, the quality and volume of similar foreign products, compared painted pictures, there is a gap. A few years later, according to the iron and steel enterprises showing painted steel market growth, a new batch of painted steel color coated paper production line in 2002, has been put into various sizes of painted steel production line a total of 30 long design capacity of nearly 180 tons. By the end of 2009, our newly built color coating production line capacity is leaps and bounds. But in addition to Baosteel, most production lines affected by the level of equipment, technology, raw material supply and other factors, so the lower unit operating rate. Choi domestic market is still in production for half board, half of imports, shortage of state. With the increase of the coating thickness Shandong Boxing color coated paper, the edge will become increasingly apparent thickening Binzhou color coated paper, and even bubbles, thereby reducing the adhesion of the coating, resulting in product packaging, transport and Processing the application process by external force appear coating off the edge, affecting users. 2. Analysis of the reason ???? thickened edge from the theoretical and practical analysis of steel coated with wet running and curing process, the viscosity of the coating, the coating thickness, speed strip and solvent evaporation rate resin curing rate, surface conditions and many other factors, such as the strip edges are likely to lead to thickening of the coating. In the actual production process, should be multi-pronged approach, one by one to analyze and resolve to take appropriate preventive measures.
