  • Detail

In 2020, the replacement proportion of water-based adhesives in the wood furniture manufacturing industry in Jinhua, Zhejiang province needs to reach 100%

recently, Jinhua, Zhejiang Province issued the "Jinhua work plan for deepening the treatment and emission reduction of volatile organic compounds (2018-2020)". With the improvement of ambient air quality as the core, we will adjust measures to local conditions, highlight key points, and implement the whole process prevention and control measures of source reduction, process control, and end treatment

goal: by the end of 2020, establish and improve the long-term management system for VOCs Pollution Prevention and control, reduce the total VOCs emission in the city by more than 24% compared with 2015, reduce the VOCs emission of key projects by more than 24000 tons, and continuously improve the ambient air quality

according to the requirements of the plan, we will focus on promoting the emission reduction of VOCs Pollution in chemical industry, industrial coating, packaging and printing, textile printing and dyeing, chemical fiber, rubber and plastic products, synthetic leather, shoe-making and other industrial industries, as well as transportation sources, living sources, agricultural sources and other fields. We will focus on the deepening treatment of key enterprises, strictly fix the emission permits of pollution sources, strengthen monitoring and law enforcement supervision, and promote the implementation of a number of key emission reduction projects

don't put samples on the support: some key contents of the plan are as follows:

first, speed up the adjustment of VOCs related industrial structure

speed up the renovation of VOCs related "scattered pollution" enterprises. All localities should comprehensively carry out the investigation of "scattered pollution" enterprises involving VOCs emissions, establish management accounts, and implement classified disposal

strictly restrict construction projects with high VOCs emissions such as chemical industry, industrial coating, packaging and printing; New key industrial enterprises involving VOCs emissions should enter the park; New, reconstruction and expansion projects that discharge VOCs should strengthen control from the source, use raw and auxiliary materials such as coatings, inks and adhesives with low (no) VOCs content, and install supporting efficient collection and treatment facilities

II. Accelerate the implementation of VOCs Pollution Prevention and control from industrial sources

1 Chemical industry

promote raw and auxiliary materials and products with low (no) VOCs content and low reactivity; The coating, ink and dye manufacturing industry should promote the use of closed production equipment

strengthen the control of unorganized exhaust emission. The storage, transportation, feeding and unloading of VOCs containing materials, the production of VOCs containing materials and the sub packaging of VOCs containing products should be closed

2. Industrial coating

(1) container manufacturing industry. Water based coatings are fully used in the processes of sanding the whole container, painting inside the container, painting outside the container, underframe painting and wood floor painting. Roll coating process is popularized for one-time sanding process

(2) automobile manufacturing industry. Promote VOCs emission control in vehicle manufacturing, modified vehicle manufacturing, auto parts manufacturing and other fields. 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

(3) wood furniture manufacturing industry. Vigorously promote the use of waterborne and UV curable coatings, and by the end of 2020, the replacement proportion will reach more than 60%; Fully use water-based adhesives, and the replacement proportion will reach 100% by the end of 2020. In the manufacturing field of flat panel wooden furniture, the use of advanced technology such as automatic spraying or roller coating is promoted

(4) shipbuilding industry. Promote the use of high solid paint, and promote the use of water-based paint inside the engine room and Shangjian. Optimize the coating process, advance the coating process to the stage of sectional coating, and by the end of 2020, more than 60% of the coating operations will realize closed spraying construction; Promote the use of high-pressure airless spraying, electrostatic spraying and other high-efficiency coating technologies

(5) construction machinery manufacturing industry. Promote the use of high solid and powder coatings. By the end of 2020, the proportion of use will reach more than 30%, and pilot the implementation of water-based coatings. Actively adopt advanced coating technologies such as automatic spraying and electrostatic spraying

(6) steel structure manufacturing industry. Vigorously promote the use of high solid coatings, and by the end of 2020, the proportion of use will reach more than 50%; Pilot implementation of water-based coatings. Vigorously promote high pressure, establish local production and service airless spraying, air assisted airless spraying, thermal spraying and other coating technologies, and restrict the use of air spraying

(7) coiled material manufacturing industry. Fully promote the use of automatic roller coating technology; Strengthen the collection of baking waste gas, with the collection rate of organic waste gas reaching more than 90%, and support the construction of combustion and other efficient treatment measures

(8) other coating enterprises using solvent based coatings should promote the use of water-based, high solid, powder, energy curing and other coatings and advanced coating processes. Paint mixing, painting, leveling, drying, drying and other processes should be carried out in a closed environment (except for the painting and touch up of large workpieces such as the hull, which cannot be closed)

3. Carry out prevention and control of VOCs Pollution from domestic sources and agricultural sources

1 Promote green decoration. Promote the use of building coatings, wood coatings, adhesives and other products that meet environmental requirements. In accordance with the requirements of the limit of harmful substances in interior building decoration materials (gb18582), strictly control the market access of decoration materials, phase out solvent based coatings and adhesives, and encourage the sale and use of low toxic and low volatile coatings and adhesives. We will actively promote the full decoration of new residential buildings. By 2020, the new multi-storey and high-rise residential buildings in the city will basically be fully decorated, and the interior and exterior walls of buildings will be decorated with coatings with low (no) VOCs content. Improve the decoration standard contract, add environmental protection clauses, and cultivate and support green decoration enterprises. It is encouraged to carry out decoration supervision and consider the inspection and acceptance of indoor air quality after decoration from the current technical level and the life cycle of 200000 kilometers of vehicles

2. Strengthen waste gas treatment in automobile repair industry. Vigorously promote the use of water-based and high solid coatings, and promote the use of water-based and high solid coatings for base paints. Promote the use of electrostatic spraying and other coating processes with high coating efficiency. The process operations such as painting, leveling and drying should be carried out in confined space or equipment. The spray gun with overcurrent, overvoltage, overload and other protective devices and solvent based paint should be sealed and cleaned. The VOCs waste gas generated should be collected and introduced into the treatment facilities to achieve emission standards

III. safeguard measures

strengthen economic policy guarantee. All localities should make overall arrangements for special funds for VOCs control, support pilot demonstration and technology promotion of VOCs control in key industries, and implement the "leader" system of environmental protection. Explore the establishment of VOCs emission reduction incentive mechanism based on environmental performance. Accelerate the establishment of diversified investment and financing mechanisms, and support financial institutions to give enterprises preferential credit for VOCs prevention and control. We will change environmental protection fees into taxes and levy environmental protection taxes. Promote government green procurement, set the threshold for fixed-point procurement access, and require the use of low volatile raw and auxiliary materials for government fixed-point bidding procurement enterprises such as furniture, printing, automobile maintenance, etc
