(6) Coil manufacturing industry.

Deeply promote the comprehensive management of VOCs in the electronic information industry.
Focus on strengthening the control of VOCs emissions from processes such as solvent cleaning, photolithography, gluing, painting, and hot pressing.

Deeply promote the comprehensive management of VOCs in the electronic information industry.

Strengthen source control.
The production of surface painting and painting of electronic terminal products is replaced by the traditional air painting process with electrostatic painting process.
The use of electrostatic spraying, curtain coating, roller coating, dip coating and other efficient coating processes are promoted to gradually eliminate high volatile organic content.
For paint coatings, use organic solvent-free or low-content organic solvent coatings.
By the end of 2019, complete the collection and treatment of organic waste gas in the electronic information industry.
The process equipment that produces VOCs such as the batching room and oven in the gluing, painting, and hot pressing processes should be equipped with airtight collection measures, and the organic waste gas collection efficiency should not be less than 80%.
Solvent-based coating organic waste gas should be equipped with high-efficiency treatment facilities such as adsorption recovery and adsorption combustion.
For water-soluble organic waste gas, multi-stage spray absorption facilities can be built to achieve stable and up-to-standard emissions.

Strengthen source control.

Promote comprehensive management of VOCs in other industrial sectors according to local conditions.
Localities should take into account the characteristics of local industrial structure and the focus of VOCs governance, and choose other industrial sectors to carry out VOCs governance in accordance with local conditions.
The wood processing industry should focus on strengthening VOCs emission control during drying, gluing, and hot pressing.
The synthetic leather industry should focus on strengthening the VOCs emission control during the drying, printing and spraying processes.
