Market Scale and Growth Rate of Waterborne Resin Industry, 2011-2015

The market size of water-based resin (water-based resin project feasibility study report) from 2011 to 2015 showed an upward trend in terms of both total volume and growth rate. In 2011, the market size of water-based resin was 3.44 million tons; in 2012, the market size of water-based resin was 3.55 million tons, up 3.2 percent year on year; in 2013, the market size of water-based resin was 3.67 million tons, up 3.4 percent year on year; in 2014, the market size of water-based resin was 3.81 million tons, up 3.8 percent year on year; in 2015, the market size of water-based resin was 3.98 million tons, up 4.5 percent year on year.

Anti-corrosion heat dissipation coating to enhance the extreme anti-corrosion heat dissipation

Now there is a kind of coating to improve the thermal infrared emissivity of the surface of the object, speed up the exchange of heat between objects, and improve the heat dissipation of heat energy. Moreover, the coating has good acid and alkali resistance, long-term corrosion resistance to acid and alkali, no discoloration or shedding, and long-term protection of the substrate. This kind of coating is the ZS-411 radiation cooling coating. We all know that there are three ways of heat exchange, convection, radiation and conduction. The heat transmitted by the object radiation has a decisive relationship with the temperature of the object. The higher the temperature of the object, the more heat the object radiates outward. This phenomenon is mainly due to the short wavelength of the object with high temperature and the high frequency of emission,

Type and Development Trend of Environmental Protection Metal Table Front Treatment Technology

For a long time, if some workpieces of household electrical appliances have higher requirements for anti-corrosion, the current common solution is to use a chemical and electrochemical reaction to form a phosphate chemical conversion film in the metal coating pretreatment process (this process is referred to as phosphating, and the phosphate conversion film formed is called phosphating film), it protects metal products such as home appliances together with post-coating to ensure that problems such as rust will not occur for 10 years or more. Although phosphating has excellent corrosion resistance and other properties, it also produces many problems, such as high energy consumption, serious pollution, containing harmful heavy metals, difficult wastewater treatment, easy to be in the pipe wall.

Problems in the development of waterborne resin industry

In the domestic application field, the high cost is the main factor restricting the wide application of water-based resin (water-based resin project feasibility study report), and some performance is still lower than solvent-based polyurethane is also an important reason. Compared with solvent-based polyurethane, water-based resin still has problems such as long drying time, weather resistance, water resistance, heat resistance, poor initial adhesion and stability, and relatively poor adhesion to low surface energy materials. At present, the development of water-based resin in China is still very unbalanced, and the application is mainly based on small and medium-sized enterprises in coastal areas using foreign technology. Domestic enterprises in the finished product testing means, production control means compared with international manufacturers.
