The hottest environmental storm forced the transfo

The environmental storm forced the transformation and upgrading of the paint and coating industry

"environmental storm" came again. Recently, the Beijing Municipal Environmental Protection Bureau, the Beijing Municipal Development and Reform Commission and the Beijing Municipal Bureau of Finance jointly issued the notice on the charging standards for volatile organic compounds. The notice points out that Beijing will begin to levy volatile organic compounds (VOCs) pollution discharge fees from October 1 in 17 sub sectors of five major industries, including furniture manufacturing, packaging and printing, petrochemical, automobile manufacturing, and electronics

coincidentally, in June this year, the national development and Reform Commission, the Ministry of Finance and environmental protection departments have jointly formulated and issued the pilot measures for 5 technical requirements of volatile organic pollutant discharge fees, which stipulates that the pilot industries of volatile organic pollutant discharge fees are petrochemical industry and packaging and printing, and will also be implemented on October 1, 2015. The above news has aroused people's attention to environmental protection issues in industries such as volatile organic compounds and paints and coatings. What is volatile organic compounds (VOCs)? What is its relationship with the paint industry? What impact will this "environmental storm" have on the industry? An interview was conducted on this

vocs is no less harmful than pm2.5

according to the definition of the World Health Organization, VOCs refers to various organic compounds with boiling points of 50 ℃ - 260 ℃ at room temperature. According to their chemical structures, they can be further divided into alkanes, aromatics, esters, aldehydes and others. At present, more than 300 kinds have been identified. The most common ones are benzene, toluene, xylene, styrene, trichloroethylene, chloroform, trichloroethane, diisocyanate (TDI), diisocyanate, etc

it is worth noting that VOCs are an important source of Urban Haze and photochemical pollution. They can react photochemically with nitrogen oxides under sunlight to generate ozone and secondary aerosol particles. They are important precursors of near ground ozone, PM2.5, etc. Its harm to human body is no less than PM2.5. When the volatile organic compounds in the room reach a certain concentration, it will cause headache, nausea, vomiting, fatigue and other symptoms, and even cause convulsions, coma, damage to the liver, kidney, brain and nervous system, cause memory decline and other serious consequences, and even cause cancer and leukemia

as a real paint country, China emits an amazing amount of VOCs every year. In 2014, the total output of coatings in China reached 16.4918 million tons. Behind such a huge output, there is not a small amount of environmental pollution and energy consumption, and such a large number of coating products will also emit millions of tons of VOCs into the atmosphere during the coating process

due to its serious harm, the state has paid more attention to VOCs governance in recent years, and all regions have also introduced corresponding measures to strengthen governance. Shenzhen has banned unqualified decoration materials such as solvent based coatings and adhesives from July 1; Jiangsu Province also issued the measures for the prevention and control of atmospheric volatile organic compounds pollution in Jiangsu Province (Exposure Draft) in early September

the paint and coating industry is "under great pressure"

it is understood that Beijing chose five industries "furniture manufacturing, packaging and printing, petrochemical industry, automobile manufacturing, and electronic industry" as the pilot to levy VOCs emission fees, because these five industries are the main volatile organic compounds emission industries in Beijing's industrial field. Although the paint and coating industry has not been included in the pilot, it does not mean that it can rest easy

it is understood that the emission of solvent based coatings is about 18% in the emission of VOCs. Among them, furniture manufacturing, automobile manufacturing and other industries are one of the main downstream industries of paint and coating. Therefore, the policy launched by Beijing this time may lead to an increase in the cost of furniture manufacturing and automobile manufacturing industries. "According to the new policies issued by Beijing, enterprises that have environmental violations such as excessive emissions of volatile organic compounds will pay four times as much as enterprises that halve the emission concentration on the basis of reaching the standard." Ma Haiying, an analyst at Zhongyu information, said that this measure will help promote relevant enterprises to speed up the adjustment and transformation, reduce volatile organic compounds emissions, and improve the quality of the atmospheric environment

coating Sony has developed an all solid battery with solid electrolyte. It is imperative to "change oil to water". It is understood that at present, China's industrial coatings can be divided into water-based coatings, solvent based coatings and powder coatings, of which solvent based coatings still occupy the leading position in the global industrial coating technology. Taking the furniture industry as an example, in the current domestic paint intelligent function setting expert system, parameter selection, database, clear windows Chinese interface, simple mouse operation market, PU paint (polyurethane paint) accounts for 78% of the market, while the utilization rate of water-based paint is only about 7%-8%

water based paint takes water as the diluent with the current R & D investment ratio of our enterprise of about 3%. 70% - 90% of its composition is water that is harmless to human body and the environment. It does not contain toxic organic solvents such as benzene and halogenated hydrocarbons and heavy metal compounds such as formaldehyde, lead and chromium. It is a safe and pollution-free environmental protection paint. About 50% of the content of traditional paint is toxic, polluting and combustible organic solvents. These solvents volatilize into the air during the coating film-forming process, which not only causes a great waste of resources, but also affects the environment and air pollution. However, despite the growing voice of water-based paint, it is difficult to overturn the market position of traditional paint, mainly because the R & D process of water-based paint is not mature at this stage, coupled with the high production cost and the limitations of physical properties of water-based paint, it is difficult to promote water-based paint

experts pointed out that the step-by-step VOCs emission charge implemented in Beijing may greatly promote the transformation of furniture enterprises and coating enterprises to "oil for water". Experts believe that paint enterprises should speed up the adjustment and transformation, implement water-based paint instead of oil-based paint, actively respond, continue to develop low VOCs environment-friendly paint water paint, reduce volatile organic compounds emissions, promote the structural transformation of the industry, guide the healthy and sustainable development of the paint industry, and improve the quality of the atmospheric environment

Zhong Yehua said that with the increasing intensity of the "environmental storm", it is imperative for the coating industry to "change oil to water". The furniture manufacturing and automobile manufacturing industries will gradually cooperate with water-based coatings, and the future demand of the paint and coating industry will slowly be squeezed out by water-based coatings. Therefore, the demand for traditional oil solvent products, including solvent oil series products, will also shrink year by year
