Click "coating industry" above to focus on our coating industry:
The field of industrial coating has been listed as the key control point of VOC industrial emission sources in China. The emission accounts for about 21% of the total amount of industrial sources. Reducing VOC content in coatings from the source can effectively achieve VOC emission reduction. In order to implement the relevant requirements of the law on the prevention and control of air pollution, the comprehensive work plan for energy conservation and emission reduction during the 13th five year plan and the three-year action plan to win the blue sky defense, the Environmental Planning Institute of the Ministry of ecological environment takes the lead in formulating the recommended national standard technical requirements for coatings with low volatile organic compound content, which is under the jurisdiction of the National Technical Committee for the standardization of coatings and pigments At present, it has entered the final approval and release stage.
This standard is positioned as the industry leader and coordinates with the existing mandatory national standards, recommended national standards and industry standards related to volatile organic compounds. The classification of the standard is consistent with the compulsory national standards in the corresponding fields, and the VOC content limit refers to the compulsory national standards in the corresponding fields. The author understands from the standard committee that the VOC content index of the standard will not be lower than the requirements of the compulsory national standard. On the basis of meeting the VOC emission reduction requirements of the paint industry in the "three year action plan to win the blue sky defense war", taking into account the actual situation of the paint industry, reflecting the demand of leading the development of the industry.
After the implementation of the standard, it can play a positive role in promoting the technical progress of the coating industry, promoting the use of environmental protection coatings, limiting and eliminating high VOC content coating products, improving the production and construction working environment, and strengthening environmental supervision and management.
From a global perspective, environmentally friendly coatings with low pollution are the development trend of coating products in the future. They have occupied more than 70% of the market in developed countries and regions abroad, but less than 50% in China at present, and there is still a large space for improvement. Source substitution is an effective way to control VOC pollution in coatings. To control VOC content in products and to use low VOC content coatings instead of high VOC content coatings can effectively reduce VOCs emissions in the use process.
In order to help enterprises in the coating field and upstream and downstream industry chains actively respond to the upcoming national standards, we specially invited Cao Yacheng, director of CNOOC Changzhou coating Chemical Research Institute Co., Ltd., to bring you a live broadcast course, and made in-depth exchanges with peers on the theme of "Application Research of acrylate coating meeting VOC limit requirements in new strong standards" face to face Flow. Director Cao Yacheng is mainly engaged in the research and development of acrylic acid, polyester, special resin and coating, presided over and participated in a number of scientific and technological projects of China National Offshore Oil Corporation, CNOOC Energy Development Co., Ltd., Jiangsu Province and Petrochemical Association, and applied for 8 national invention patents. In this live broadcast course, he will share industrial application cases of a variety of environmental protection coating products to help engineers of enterprises find ways and ideas to control VOC content in coatings.
