How to reduce harmful substances in industrial coating supplies?

The control of harmful substances in industrial coatings is mainly achieved through three aspects: source substitution, process optimization, and end of pipe treatment:
Source substitution
Prioritize the use of low volatility products such as water-based coatings and powder coatings to replace traditional solvent based coatings. For example, automobile manufacturing companies can reduce VOCs emissions by over 60% by switching to water-based coatings.  ‌
Process optimization
Closed production: Reduce volatilization through a sealed paint booth and efficient filtration system
Equipment upgrade: adopting automatic spraying robots, efficient rotary cup spraying and other technologies to improve adhesion efficiency to 60% -80% and reduce paint waste
Formula adjustment: Reduce the feeding temperature, use low volatility raw materials, and reduce human errors through a microcomputer control system
end treatment
The combination process of activated carbon adsorption concentration catalytic combustion (RCO) is adopted to concentrate low concentration exhaust gas and catalyze its decomposition into carbon dioxide and water, with a purification efficiency of over 95%. Some enterprises have achieved stable and compliant emissions through this technology.  ‌
