Powder Coating: Low Carbon Environmental Protection into A New Industry

Recently, the guangdong environmental protection bureau announced the pearl river delta region of 2017 ozone pollution prevention and control of special operation plan (draft) ", put forward the specific requirements of VOCs emission paint coating, for coating enterprise peak production, limit production, production measures, in order to strengthen the reach VOCs emission control in the pearl river delta, curbing ozone pollution in autumn of 2017, push ozone concentration drops into the channel, improving the regional environmental air quality. In fact, the paint industry as key domains VOCs emission reduction, management difficulty is very big, especially in the use of link, such as steel structure, containers, ships, fence netting, traffic line markings, such as outdoor homework coating, VOCs governance at the end of the operability is poor. Although government departments are pushing for new materials such as waterborne coatings, the "oil ban order" that restricts organic solvents is implemented, but the traditional solvent paint still accounts for half of the market. However, the innovation pattern of coating industry in China has begun to improve, and the application of new materials and new technologies in the coating industry is on the rise. According to the data, China's powder coating industry produced 1.7 million tons in 2016, up 13.4 percent year on year. Because the powder coating has no solvent, pollution-free, recyclable, environmental protection and energy conservation, it has become the "new pet" of the industry, and a number of large-scale coating enterprises are planning to lay out the field of powder coating of VOCs zero emission. Recently, in environmental protection to strengthen the inspection for the control of air pollution 7 rounds to strengthen supervision, check 5322 enterprises (units), found 1389 involved gas enterprises, environmental problems including VOCs governance problems in 536, 38.6% of the time inspection found that environmental problems. In terms of industry, coating and spraying are the primary problems, and it is common for enterprises not to build or idle or stop the operation of VOCs. "The coating industry is characterized by concentrated emission and pollution, and about 7 million tons of solvent need to be volatile each year, which is more serious than the pollution of automobile exhaust." Senior coating industry expert, suzhou Austin new material technology co., LTD chairman Yang xianghong said. Yang said that China is a big producer of coatings, but it is not a great power. According to the above 1,400 enterprises, the annual output of China is close to 20 million tons and its output value exceeds 400 billion yuan. However, some of the core technologies of high-end coating products are not mastered, and most of the coatings used in high iron are from foreign companies. "A lot of low-end paint products have become the main VOCs emission sources in the industry. However, due to a variety of factors, solvent-based coatings still have huge market demand for a certain period of time. It is understood that VOCs emissions have been a key issue in the green environment, and the coatings industry, as a major emitter of VOCs, has repeatedly landed on the "list" of polluting industries. "Much starker choices-and graver consequences-in" issued by the ministry of the "volatile organic compound pollution prevention and control work plan is put forward, the key container, automobile, furniture and other manufacturing industries industrial coating VOCs emission control, promote the use of water-based coating in related fields and high solid powder coatings. But Yang pointed out that the above two kinds of coatings still contain a certain amount of solvent, and the monitoring of related emissions in the open air is difficult.
