The development of the coatings industry should take the reduction of VOC as the main direction.

rapid development of
coatings industry has also brought some negative effects, coating products in the coating process will also emit millions of tons of VOC into the atmosphere. Reducing the pressure on the environment and energy caused by the production and coating process should be a key task of the "13th Five-Year Plan" of the coating industry. Improving the coating process of coatings, increasing the use of coatings, reducing paint mist waste and VOC emissions are the direction of the paint industry.
recently, the Ministry of Finance, the National Development and Reform Commission and the Ministry of Environmental Protection jointly issued the "Pilot Measures for Volatile Organic Sewage Charges", which includes the petrochemical industry and the packaging and printing industry, and will come into effect on October 1 this year. The main reason for the formulation of this policy is that, because china's atmospheric control situation needs to further control volatile organic matter, the current monitoring, governance, control measures are inadequate. The state environmental protection department hopes that enterprises can effectively implement the policy to achieve the goal of managing VOC or to alleviate VOC emissions.
volatile organic compound VOCs refers to the general term for volatile organic compounds under certain conditions. VOCs, as one of the four major overall pollutants, are an important cause of PM2.5 and photochemical pollution. However, VOCs were relatively late in markets such as desulfurization and denitrification, and voCs were included in the scope of air pollution prevention and control for the first time in 2010.
According to the pilot method, the pilot scope is crude oil processing and petroleum products manufacturing, organic chemical raw materials manufacturing, primary form plastics and synthetic resin manufacturing, synthetic rubber manufacturing, synthetic fiber single (polymer) body manufacturing and storage industry, as well as packaging and printing industry packaging and decoration printing.
provinces, autonomous regions and municipalities directly under the Central Government may increase the pilot VOCs sewage charges in accordance with the actual situation in the region, and formulate measures to increase the VOCs sewage charges in the pilot industries. The VOCs sewage charges collected by the local environmental protection authorities shall be paid in full to the state treasury and incorporated into the general public budget management.
, the scheme stipulates that enterprises in pilot industries that emit VOCs directly into the atmosphere should pay VOCs sewage charges. VOCs emitted from each outlet are charged VOCs sewage charges, which are calculated according to the amount of pollution equivalent to VOCs emissions, and the pollution equivalent is tentatively set at 0.95 kg.
2014, China's total coating production reached 16.4918 million tons. Behind such huge production is significant environmental pollution and energy consumption, and coating products of this base emit millions of tons of VOCs into the atmosphere during the coating process. Reducing the pressure on the environment and energy caused by the production and coating process should be a key task of the "13th Five-Year Plan" of the coating industry.
At present, China's low-polluting paint growth rate is much lower than the growth rate of the country's total paint production, in recent years only water-based
bicoal coatings
accounted for a considerable proportion of the growth rate, the overall proportion of low-polluting paint is still negative growth.
low-carbon environmental protection, energy conservation and emission reduction work can not be separated from the development of paint technology. During the 13th Five-Year Plan period,
water-based coatings
, high solid sub-coatings, solvent-free coatings, photo-curing coatings, radiation curing, functional new external insulation coatings and other environmentally friendly, resource-saving coatings, as well as single-line production capacity of 30,000 tons / year and above products and production lines. In the process of research and development, production and application of various types of coatings, many problems have been encountered at this stage and need to be solved during the 13th Five-Year Plan period. For example,
water-based wood coating
the combination of water in the process of drying into a film is not easy to discharge, resulting in wood absorption of the phenomenon of burst ribs and so on. Late water-based
wood coating
should promote cold infrared drying, microwave drying and other technologies to promote the discharge of combined water.
Overall, the coating industry must promote industrial upgrading through technological upgrading, from high pollution, high energy consumption to low-carbon environmental protection direction, increase investment in green coating technology research and development, can not be eliminated from the coating production line to improve and upgrade, achieve VOC organized emissions, and paint coating process improvement, increase paint uity, reduce paint waste and VOC emissions.
