Zhuzhou spraying industry opens the era of “water-based paint” VOC governance to ensure Zhuzhou blue

In the battle to defend the blue sky, Zhuzhou City delivered a beautiful report card in 2018: 288 days of good air quality, 74 days more than in 2013, and air quality improved for 6 consecutive years.
Defend “Zhuzhou Blue”, what should we do in 2019?
On February 18, the Office of the Zhuzhou Municipal Ecological Environmental Protection Committee issued a key emission reduction project for the “Blue Sky Defense” in 2019. It plans to control volatile organic compounds, change boilers to natural gas or centralized heating, kiln desulfurization or change to natural gas, asphalt We have implemented 95 specific projects to clean the air and protect the blue sky in four aspects: unorganized emission control and volatile organic compound control in the ready-mixed concrete industry.
Eliminate the “paint smell”
The spraying industry opens the era of “water-based paint”
Regardless of the level of environmental protection inspectors, the odor nuisance around Tianxin High-tech Park and Tianyuan District Auto Parts Park has always been a hot spot for complaints.
The “paint smell” hated by surrounding citizens is actually an invisible volatile organic gas, mostly pollutants generated by the use of paint and solvents during vehicle spraying and surface treatment.
Liu Huiqing, head of the Total Section of the Municipal Environmental Protection Bureau, introduced that volatile organic gases are important precursors for PM2.5 and ozone generation.
“To put it simply, this kind of volatile organic compounds do not directly produce PM2.5 and ozone pollution, but they will react with various pollution factors in the air, thereby increasing the concentration of PM2.5 and ozone in the air. “Liu Huiqing introduced that in recent years, our city has vigorously shut down industrial enterprises, but the decline in the average concentration of PM2.5 and ozone has not matched the reduction in industrial pollution. The increase in emissions of volatile organic compounds is an important reason. one.
Among the key emission reduction projects in the Blue Sky Defense War this year, volatile organic compounds control projects accounted for 26, involving rail transit equipment and parts manufacturing and coating, auto parts manufacturing, rail transit parts finishing, cemented carbide manufacturing, furniture manufacturing, etc. Industries.
Liu Huiqing introduced that in these 26 treatment projects, in addition to improving the production process, sealing, collecting and treating volatile organic compounds, a more important measure is to start “water-based paint” instead of “oil-based paint” in some companies. Work.
It is understood that the most important reason to use “water-based paint” instead of “oil-based paint” is that “water-based paint” has no or few volatile organic compounds. Using it to replace “oil-based paint” is to control pollution in spraying and surface treatment. Fundamental move.
According to requirements, Hunan Baosteel Wheel Co., Ltd., Zhuzhou Rongqi Technology Co., Ltd., and Zhuzhou Lehuan Furniture Industry Co., Ltd. will replace “oily paint” with “water-based paint” after September 30; CRRC Zhuzhou Electric Locomotive Co., Ltd. Before November 30 next year, through adjustment, optimization and upgrading of production technology, the coating division will be integrated, and the work of 5 dry spray booths and the oil conversion of subway vehicles to “water-based paint” will be completed in advance; the work system and specifications will be issued, and zero Component suppliers provide “water-based paint” products, and fully implement environmentally-friendly “water-based paint” instead of ordinary paint.
