Fighting against the blue sky, Jiangsu Xuzhou held a water-based paint technology matchmaking meeting

In the afternoon of June 28, in order to promote the control of source volatile organic compounds (VOCs)Water-based paintReplacement of raw materials, water-emission reduction at the source of the "surface coating industry (construction machinery)" co-sponsored by the Chinese Academy of Environmental Sciences, Xuzhou Environmental Protection Bureau and water-based platformcoating"Matching with Coating Technology" was held in Xuzhou, Jiangsu Province. Wang Guoqing, director of the Chinese Society of Environmental Sciences, Ye Xiaoliang, deputy director of the Atmospheric Division of the Xuzhou Environmental Protection Bureau, Zhang Jun, director of the waterborne platform, and more than 150 other engineering machinery manufacturing companies Experts of environmental protection painting technology attended the meeting.

It is reported that in recent years, significant progress has been made in the control of sulfur dioxide (SO2), nitrogen oxides (NOx), and smoke and dust, but VOCs emissions are still increasing. Therefore, in order to fight against the blue sky, controlling VOCs and NOx emissions will be The next priority work tasks.

Ye Xiaoliang, deputy director of the Atmospheric Department of the Xuzhou Environmental Protection Bureau, stated that according to the work tasks proposed in the "Xuzhou City 2018 Volatile Organic Compound Pollution Prevention Work Plan", 738 companies from construction machinery, vehicles, furniture, ships, printing and packaging will be required. Key enterprises completed the replacement of clean raw materials, and fully used water-based coatings and adhesives with low VOCs content. Enterprises that have been included in the key monitoring of VOCs emissions must complete their governance by the end of June and complete the installation of VOCs online monitoring facilities by the end of October.

Data show that Jiangsu Province, as an important base for construction machinery manufacturing nationwide, has a total annual discharge of 10945 tons of VOCs in the construction machinery manufacturing industry, accounting for about 1/3 of the country.

Among them, the annual use of Xuzhou Construction Machinery Group and major supporting supplierspaintThe amount is about 8,000 tons, and the VOCs emissions amount to 4,800 tons, accounting for about 44% of the province. Therefore, the replacement of water-based technologies by construction machinery manufacturing enterprises in Xuzhou City has important environmental protection significance for significantly reducing VOCs emissions in Jiangsu Province, and will also have an important impact on other construction machinery manufacturing bases in Jiangsu Province and the country.

In addition, according to experts from water-based platforms, 95% of the world ’s containers are manufactured in China and are concentrated in the five largest container manufacturing plants. The high concentration of the industry makes the development of the industry unique.

According to the statistics of the Ministry of Environmental Protection, the annual paint usage of the container industry is about 168,000 tons, and the VOCs emissions are about 80,000 tons. After using water-based coatings, the annual VOCs emissions are reduced by 90%. As of the end of 2017, China's container industry accounted for 99% of the production of water-based coatings, except for only 1% of special containers.

After China's container manufacturing industry is water-based, whether the construction machinery manufacturing industry can become the second industry to achieve water-based production requires the concerted efforts of all parties, not only the continuous supervision and supervision of government agencies, but more importantly, the company itself must also Act consciously and continuously promote technological innovation.
