coating enterprises gathered, VOC (volatile organic compounds) pollution is serious.
studies have shown that when VOC reaches a certain concentration, people experience headaches, nausea, vomiting, fatigue, etc. for a short period of time, and in severe cases convulsions, coma, and damage to the liver, kidneys, brain and nervous system. VOC has been shown to have a huge impact on human health. VOC pollution can not be underestimated, traditional solvent-based

in order to promote enterprises from the source to reduce VOC emissions, Kunshan Environmental Protection Bureau held a "Kunshan coating water-based chemical industry linkage summit forum." Nearly 250 people from the coating industry chain upstream and downstream enterprises participated in the forum, including water-based platform member units and Kunshan area coating enterprises. "Kunshan existing paint spraying enterprises more than 100, the size of more than 400 spray lines, the annual paint solvent use of more than 10,000 tons, VOC pollution can not be underestimated." Chen Yinhong, deputy director of the Kunshan Environmental Protection Bureau, said that as early as 2008, Kunshan began to explore effective methods of VOC pollution control. Changing the paint to water-based paint with water as a solvent will significantly reduce VOC emissions. "Oil-to-water" has become an option to guide enterprises to reduce emissions and increase efficiency. "At present, the domestic environmental policies have been introduced. Under this pressure, the process of 'oil-to-water' will be greatly accelerated. In the future, coatings will be

, ultraviolet curing coatings, high-solid solvent-containing coatings direction, traditional solvent-based coatings will gradually be replaced. Today, 'oil-to-water' has been accepted by Kunshan enterprises and given implementation, and in the market operation has taken root. Chen Yinhong said. Water-based paint production line without pungent odor, a number of enterprises to join the ranks of "oil-to-water"
Nanbao Resin (China) Co., Ltd. Chairman Sun De Cong admitted that the original paint production line taste pungent. And it is understood that by the end of 2015, VOC sewage charges collection and management measures will be introduced. Therefore, changing the production mode, products in line with environmental requirements, is a sustainable development of enterprises a wise choice. At present, Nanbao resin has invested nearly 30 million yuan, set up a research and development team of about 50 people, modified the existing production line, specializing in the development and production of water-based industrial paint.
Sun De cong said, now Kunshan has a lot of production enterprises to take the initiative to join the "oil-to-water" ranks.
" 4 years ago, enterprises on the implementation of C2C environmental protection strategy, production lines all use water-color paint, each month the product spraying area of up to 100,000 square meters. Wang Haixuan, executive director of Good Kids Group, said that when water-like paint was first used, production costs increased and consumers did not buy it, resulting in low sales. But with the improvement of people's awareness of environmental protection, the increase in sales has led to a decline in operating costs. This year, a paint production line of Yaoma Motor Industry China Co., Ltd. was converted to water-like paint. Jiang Shunfeng, an employee who has worked for 12 years, said: "There is almost no taste on the water-like paint line, and the pungent smell coming from the nearby paint spray line makes us very uncomfortable." "VOC emissions have been significantly reduced, product quality improvement and wider sales
" In recent years, the company will replace organic solvents with water, research and development has made a major breakthrough. And the product has also formed a variety, has been introduced with flame retardant function
water-based wood paint
, as well as for aluminum magnesium alloy, plastic, glass rubber and other materials coating water-based paint. This year, the company's water-powered industrial paint sales have reached more than 200 million yuan. Sun said. At the same time, the enterprise will be the original two paint production lines, to produce water-powered industrial paint, the annual emission reduction VOC 1200 tons. After that, the remaining paint production lines will be fully implemented "oil to water." Since 2012, Kunshan White Magnolia Furniture Co., Ltd. began the trial production of water-based coatings, using the world's most advanced German and Italian water-based coatings automatic spray line, the physical properties of products have reached the standard of oily coatings, through the United States Cabinet Association (KCMA) strict testing, and in 2014 through a higher standard of U.S. UL green certification, become China's first comprehensive water-based coating of wooden furniture enterprises. Talking about the benefits of "oil to water", the company's chairman Shen Zhongmin such as several Jane. First of all, VOC emissions were significantly reduced, in terms of 2013 production, if the use of oil paint, the total annual atmospheric VOC emissions of 1145 tons, and after the use of water-based paint, the total annual VOC emissions of only 19 tons, a reduction of up to 98%. Secondly, the efficiency of spraying has been greatly improved, before the efficiency of oily paint spraying is only 35% to 40%, and now the efficiency of water-like paint painting jumped to more than 79%, not only to reduce costs, but also improve product quality. At present, the annual export value of more than 50 million U.S. dollars, by the European and American markets welcome. Sun De Cong said that the domestic water-based industrial paint and coatings and water-based spraying equipment mature technology, the comprehensive cost is not much higher than oily coatings. Early transformation and upgrading, enterprises will benefit early.
