Powder Coatings - New Materials,New Technologies

The powder coating is a solid powder coating with a fine powder, which can be transferred to the coating by powder, which is cured by baking and solidified into a coating. According to Yang xianghong, the powder coating achieves zero waste and zero pollution in the manufacturing process, and the leftover materials produced in the production can also be recycled. Powder coating can meet the needs of anti-corrosion and decoration in many fields, and the powder coating has high efficiency. The area of coating of powder coating is more than double that of traditional solvent. In terms of cost, the price of powder coatings is also the lowest in several types of coatings commonly used. At present, the powder coating has been widely used in household appliances, automobile wheel hubs, metal doors and Windows, etc., and the market share of the industry has been increasing, now it is about 10%. It is reported that the powder coating enterprises in China mainly distribute in the coastal areas, the Yangtze river delta, the pearl river delta and the bohai rim area of the three major coatings industry base powder coating sales account for 94% of the country. "10% market share tells us that powder coating meets the needs of environmental protection and market, and has become the third major coating after latex paint and solvent coatings. If we want to further promote the development of powder coatings more rapidly, we must tackle its weaknesses. If you can successfully reduce the curing temperature, you can not only reduce the energy consumption during the coating process, but also apply the powder coating to a wider range. Yang xianghong said. It is reported that the guangdong coating industry association recently organized a number of paint enterprises and experts to discuss the application of powder coatings in wood furniture. The association secretary-general lu water column is put forward at the seminar, transformation and upgrading of coating of environmental protection should fully consider various options, should not be confined to water based on this approach, the collocation of powder coatings and wood furniture is worth attention and consideration. In accordance with the "much starker choices-and graver consequences-in" volatile organic matter pollution prevention and control work plan, before the end of 2017, 60 production capacity of 5.6 million teu container production enterprises to complete alternative, water-based environmental protection coating and construction at the end of the treatment facilities; Before the end of 2020, the national 2020 automobile manufacturing enterprises, 3400 wooden furniture production enterprises, 600 shipbuilding enterprises, 1300 engineering machinery manufacturing enterprises, 5000 steel production enterprises, will complete low volatile paint replacement, low emissions of VOCs coating process and terminal management project construction. Yang xianghong said that to achieve the above target, the upgrading of the coating industry is imminent. At present, the annual usage of paint is about 25 million tons, the traditional solvent coating is about 54 %, the water-based coating is about 35 %, the powder coating is about 10 %. If we want to eliminate the solvent, we must increase the research and development of core technologies, develop more stringent VOCs emission standards, and accelerate the upgrading and transformation of backward production capacity. At the same time, the government has also responded to the application of new materials and new technologies to accelerate project approval and support. Yang Xianghong, for example, according to the same capacity, and powder coating of the company covers an area of only half of the traditional solvent coating enterprise production cost, the new material, new technology support to realize mass production, the old backward production capacity of natural can only choose to upgrade or obsolete. In Yang Xianghong view, powder coating to be promoted, the original production equipment, coating equipment all need to be replaced, but also to break the original pattern of production and marketing with the chain, there is a certain difficulty. "A domestic agricultural machinery leading enterprise old total said, too much trouble to use water-based coatings, cost is high, if use powder coating, to change things too much, or a traditional coatings with comfortable. So, it's not just the technology, it's the idea. The government should adopt a very different policy towards the old and new technology, the support of the support, the restriction of the restriction, the elimination of the elimination, only then can improve the overall level of the paint industry."
