powder coating do no harm

With people's increasing awareness of environmental protection, in powder coating, people more and more is also high. Powder coating has become a hot product in the market, its VOC content 

is low, easy to clear, usually easier than the liquid coating construction, the formation of the film durability is good. It replaces liquid coating as a market trend. What about the use of powder coating in our country's furniture? First of all, China's annual per capita consumption of furniture is low. According to statistics, China's annual per capita furniture consumption level of about $12, compared with the United States and Europe, less than 5%. In particular, the two or three line market, the vast rural market share of furniture is lower, which also brings great opportunities for the development of the furniture industry, but also makes the prospect of a huge paint industry. Secondly, due to the global increasingly high demand of environment-friendly coating, powder coating has become popular coating market products, the VOC content low, easy to remove, is usually higher than the liquid coating easy construction and formation of the durability of the coating film. It replaces liquid coating as a market trend. Powder coating is a kind of coating. However, it has its own characteristics.

Different to traditional solvent based coating, for dry powder, and in the past compared to the old method is by flame spraying and preheating coating, now basically using electrostatic spray, the first powder coating on the surface of the coating material, again through the oven 200 degrees about baking temperature leveling and curing. Powder coating in the traditional paint, the advantages of no poison, no pollution, no waste, and water-based paint, known as the environmental protection paint. The disadvantage is that: some of the high requirements of coating such as the car, the surface gloss and leveling are still not up to the requirements, impact resistance and other mechanical properties have yet to be improved. In the production of polyester resin, the choice of some alcohol or acid can improve the glass temperature, or reduce the amount of alcohol used to reduce the temperature of the resin glass to improve the glass temperature of polyester resin. In the powder coating formulation design to reduce low glass transition temperature of the polymer usage, such as leveling agent and brightener to ensure the powder coating system of glass transition temperature is not reduced. Production and strip down broken sheet should be sufficient cooling and then enters the milling process, milling should be appropriate to reduce the feed speed, increase induced draft fan air volume, air inlet installed air conditioning to control the temperature of grinding. However, if before milling grinding sheet cooling Xiabu Lai, behind the means is not to good effect, can consider the broken sheet of forced cooling method were treated with low temperature, which is equipped with 

air conditioning more effective.
