The first national low volatility organic coating technical standard for low-VOC coatings issued by Shenzhen has been fully implemented since March 1 this year. This standard specification combines the industrial status of Shenzhen with roads and traffic signs. Manufacturing, container manufacturing, minibus vehicle manufacturing, large and medium vehicle vehicle manufacturing and other industries use coatings to control, refer to domestic advanced standards to regulate the requirements for volatile organic compounds (VOCs) content in coating products. Environmental experts believe that This will be a big step for the paint industry to complete the green transformation and will continue to improve the atmospheric environment in Shenzhen.
In order to help companies successfully carry out VOCs pollution rectification work and ensure the effective implementation of standards, on March 9th, the Shenzhen Municipal Commission of Habitat and Environment and the Shenzhen Institute of Metrology and Quality Inspection held an advocacy meeting. The meeting focused on the current industrial source VOCs in Shenzhen. The remediation situation and relevant policy requirements were introduced. Around the relevant requirements of the “Low VOC Organic Coatings Technical Specifications”, interpretations were made from the aspects of paint production, sales companies, paint application companies, and public participation. The municipal environmental protection department stated that The next step will be to conduct a one-on-one verification and assessment of the implementation of the “one enterprise and one policy” for provincial key VOC emission companies, and to urge the key city monitoring enterprises to complete comprehensive renovation by June. From the second quarter of this year, the environmental protection department of Shenzhen The market supervision department will continue to carry out special inspections to strictly inspect the sales and use of paint products that do not meet the requirements of the standard and will be punished according to law.
It is understood that VOCs are precursors of ozone generation in the ambient atmosphere, and are important causes of photochemical pollution and fine particulate matter (PM2.5) pollution. Since 2015, the number of consecutive days of ozone as major pollutants has exceeded PM2.5. , Become a primary pollutant in Shenzhen. VOCs have a wide range of emission sources. Among them, the use of coating products is one of the most important emission sources. The cost of closed collection ends in industrial coating production processes is high, and supervision is difficult and needs to be reduced from the source. The generation of VOCs, and the realization of the source control of VOCs emissions. To this end, since 2014, Shenzhen has successively issued a series of special economic zones such as construction and decoration materials and adhesives, automobile maintenance, and limited quantities of harmful substances in finished furniture and raw and auxiliary materials. Regulations. The implementation of more stringent paint technical specifications indicates that the industrial source VOCs treatment in Shenzhen has entered a comprehensive deepening stage, will greatly reduce VOCs emissions, inhibit ozone pollution, and polish the 'Shenzhen Blue'.
In the past year, the Shenzhen Municipal Human Settlements Environmental Committee focused on improving the quality of the environment. It used standardized means to implement the congressional battle, made great efforts to tackle major challenges, and made major improvements. It accelerated the upgrading of environmental infrastructure. Solid advancement of water, air, and soil pollution prevention, along with With the continuous implementation of a series of environmental governance projects, Shenzhen’s ecological and environmental protection has been at the forefront of the country. It has achieved both economic and ecological benefits “double improvement”. The excellent ecological environment has also greatly improved the public's happiness index.
