[China paint information]

recently, in order to accelerate the prevention and control of volatile organic compounds (VOCs) pollution and effectively improve the quality of the atmospheric environment, Hubei Province has formulated and implemented the three-year action implementation plan for the prevention and control of volatile organic compounds pollution to transfer heat from high-temperature objects to low-temperature objects (hereinafter referred to as the "plan"). According to the plan, by 2020, based on the national planning base of 987000 tons in 2015, the total emission of VOCs from active sources in Hubei Province will be reduced by 10%, and the emission reduction of key projects will reach 99000 tons. We will comprehensively complete the remediation of VOCs Pollution in key industries and regions in the province, and establish and improve the VOCs Pollution Prevention and control management system with improving ambient air quality as the core

in combination with the contribution of industrial emissions, the plan focuses on promoting the prevention and control of VOCs Pollution in petrochemical, chemical, industrial coating, packaging and printing, medicine, electronic information, rubber and plastic products, printing and dyeing, coking and other industrial industries, as well as transportation sources, living sources, agricultural sources, and a number of key projects. The specific implementation is divided into three stages, and the objectives of each stage are as follows: the first stage: 2018 is the start-up implementation stage; The second stage: 2019 is the deepening implementation stage; The third stage: 2020 is the consolidation and strengthening stage

the main relevant contents of the "plan" for China's paint finishing are as follows:

strengthen the adjustment of industrial structure

accelerate the comprehensive renovation of "scattered and dirty" enterprises. All localities should comprehensively carry out the screening of "scattered pollution" enterprises involving VOCs emissions, establish management accounts, and implement classified disposal. Wuhan and its surrounding areas should complete the clean-up and rectification work in accordance with the law and regulations by the end of 2018. The "scattered pollution" enterprises involved in VOCs emissions are mainly chemical enterprises such as paint, ink, synthetic leather, rubber products, plastic products, chemical fiber production, printing, furniture, steel structure, wood-based panel, injection molding and other manufacturing and processing enterprises using solvent based paint, ink, adhesive and other organic solvents, as well as outdoor spraying automobile maintenance operations

strict environmental access for construction projects. We will raise the environmental protection access threshold for key VOCs emission industries and strictly control the emission of new pollutants. Key areas should strictly restrict construction projects with high VOCs emissions, such as petrochemical, chemical, packaging and printing, industrial coating, etc. New and relocated enterprises with large VOCs emissions should enter the industrial park and meet the planning requirements. All new, modified and expanded construction projects will implement the equivalent or multiple reduction and substitution of VOCs emissions, and implement the substitution scheme into the enterprise emission permit and incorporate it into the environmental law enforcement management. New, reconstruction and expansion projects involving VOCs emissions should strengthen control from the source, use raw and auxiliary materials with low (no) VOCs content, strengthen the collection and treatment measures of VOCs fugitive emissions, and install efficient treatment facilities

implement peak shift production in industrial enterprises

accelerate the implementation of VOCs Pollution Prevention and control from industrial sources

accelerate the comprehensive treatment of VOCs in the chemical industry. We will strengthen the control of VOCs in pharmaceutical, pesticide, coal chemical industry (including modern coal chemical industry, synthetic ammonia, etc.), coatings, inks, adhesives, dyes, household chemicals and other chemical industries. In 2018, the LDAR work will be gradually promoted in the pharmaceutical, pesticide, coating, ink, adhesive, dye and other industries. In 2019, the LDAR will be fully implemented in the modern coal chemical, pharmaceutical, pesticide and other industries in key regions

strengthen the control of VOCs in industrial coating. Comprehensively promote the VOCs emission control of industrial coating in automobile, wood furniture, shipbuilding, engineering machinery, steel structure, coil and other manufacturing industries, promote the use of green raw and auxiliary materials with low (no) VOCs content, and complete the collection and treatment of organic waste gas in the industrial coating industry in the province by the end of 2019, and basically complete it in key areas by the end of 2018

(1) automobile manufacturing industry. The new film blowing machine produced by promoting VOCs emission control in the fields of vehicle manufacturing, modified automobile manufacturing, automobile parts manufacturing and so on meets the diversified needs of the market. Promote the use of high solid and water-based coatings, and use "three coating and one drying", "two coating and one drying" or no intermediate coating and other compact coating processes; Promote high-efficiency coating processes such as electrostatic spraying, and encourage enterprises to adopt automatic and intelligent spraying equipment to replace manual spraying. Equipped with a closed collection system, the organic waste gas collection rate of vehicle manufacturing enterprises is not less than 90%, and that of other automobile manufacturing enterprises is not less than 80%; Build efficient treatment facilities such as adsorption combustion for paint waste gas and combustion treatment facilities for drying waste gas to achieve emission standards

promote the comprehensive treatment of VOCs in other industrial industries according to local conditions. All regions should choose other industries to carry out VOCs governance according to local conditions in combination with the characteristics of local industrial structure and the focus of VOCs governance. The wood processing industry should focus on strengthening drying, and pay special attention to the treatment of VOCs emission in the process of drying, gluing and hot pressing of tiling-/trim-in-place technology used to produce cup products. The synthetic leather industry should focus on strengthening VOCs emission control during drying, printing and spraying. The coking industry should focus on strengthening VOCs emission control in the recovery process

orderly carry out the prevention and control of VOCs Pollution from living sources and agricultural sources

in order to effectively improve the ambient air quality, the province should not only complete the task of VOCs emission reduction in key industries, but also strengthen the treatment of VOCs from living sources such as building decoration, automobile repair, dry cleaning, catering and agricultural and rural sources

1. Building decoration industry. Promote the use of building coatings, wood coatings, adhesives and other products that meet environmental requirements.
