environmental protection starts with the prohibition of the sale of solvent based paint in Shenzhen

July 16, 2015

[China paint information] recently, Shenzhen has made new moves to control air pollution. From July 1, unqualified decoration materials such as solvent based coatings (paints) and adhesives, which seriously endanger the health of citizens, will be completely banned, making it the first city in the country to restrict the sales and use of solvent based coatings (paints). In the same period, non road mobile machinery with substandard exhaust will also be prohibited from being used in construction sites, factories, ports and wharves in Shenzhen

it is not new to control the air pollution caused by paint. Previously, Lanzhou also issued the "implementation plan for air pollution prevention and control in Lanzhou in 2015", which also made clear requirements for the annual control indicators of pollutant concentrations in counties and districts. The office of the diversity group, the leader of the air pollution prevention and control work in Hebei Province, released the "three-year (2015-2017) action plan for the in-depth control of pollution in the atmosphere of Hebei Province, the results of which should be shared by the industry". Later, on June 10, the Beijing Municipal Environmental Protection Bureau held a press conference to release five new air pollutant emission standards issued by Beijing. According to specific regulations, after 2017, the furniture manufacturing industry in Beijing will completely prohibit the use of oily coatings, namely paint spraying

the successive introduction of various schemes tells people that the air pollution caused by paint is serious, and the use of polluting paint should be prohibited. According to the data of the environmental testing center of China Interior Decoration Association, the number of deaths caused by indoor air pollution in the country is as high as 111000 every year, about 304 per day, which is equivalent to the number of deaths caused by car accidents in the country every day. The new national standard is basically based on the standard of GB8624 (2) 006

people suffer from it under the traditional paint

paint uses organic solvent as diluent, which consumes energy, pollutes the environment, is toxic, harmful, flammable and explosive. In foreign countries, the production and application of traditional paint have been expressly prohibited or restricted. In 2004, the EU has legislated to prohibit the production and use of paint. But in China, the production and application of paint is still popular

paint should be diluted with the help of organic solvents extracted from oil and coal, which not only consumes fossil energy, but also contains a large number of toxic and harmful substances such as benzene, toluene, xylene, formaldehyde, etc., and its volatilization period is as long as more than ten years. Harm of paint to the environment according to the latest research data, toluene and xylene in paint will produce certain photochemical reactions after entering the atmosphere, which will have a certain destructive effect on the ozone layer

as a killer of human air, haze seems to be only related to automobile exhaust and factory exhaust in people's concept. In fact, paint is not only a healthy ERODER, but also one of the sources of haze. PM2.5 is an important cause of haze weather. Although its main sources are automobile exhaust emissions accounting for 30%, VOC (volatile organic compounds) emissions accounting for 21%, and residues from combustion in other daily power generation, industrial production and other processes accounting for 49%, it has been recently reported that about 18% of VOC emissions are caused by solvent based paint emissions. With the aggravation of haze weather, paint has become a driving force

the harm of paint is not only that. Traditional paint often uses a large number of toxic and harmful volatile organic solvents as diluents, and some products also use curing agents containing free TDI, resulting in a lot of air pollution. Studies have shown that long-term inhalation of volatile gases from these solvents and curing agents can lead to aplastic anemia, leukemia, tuberculosis, pleurisy and other serious diseases. The cases of "living in a new house, the child has leukemia" and "the abortion of the victim of interior decoration, and the fetus is black" abound, which is shocking. Formaldehyde, radon, benzene, ammonia, toluene, xylene, TVOC... These indoor air pollutants surround nearly half of the world's people, resulting in respiratory diseases, chronic lung diseases, tracheitis, bronchitis, lung cancer and other diseases. All kinds of lessons remind people all the time that paint pollution must be brought to mind and protective measures should be taken

prohibit paint pollution Shenzhen is doing so

Liu Chuhan, director of the Shenzhen Municipal Human Settlements and Environment Commission, revealed that in order to achieve the goal of reducing PM2.5 to 33 micrograms/cubic meter this year, the Commission will launch a number of in-depth air pollution control measures from July 1

first, we should carry out in-depth treatment of volatile organic compounds. The special zone technical specification of "limit of harmful substances in building decoration coatings and adhesives" was issued, and the second phase of harmful substance content limit standard was implemented from July 1, 2015, and unqualified decoration materials such as solvent based coatings (paints) and adhesives that seriously endanger the health of citizens were comprehensively banned. Therefore, Shenzhen has become the first city in China to restrict the sales and use of solvent based coatings (paints)

secondly, the diesel engine for non road mobile machinery should be treated in depth. On July 1st, 2015, the Shenzhen Special Economic Zone officially implemented the technical specification of "limits and measurement methods of exhaust smoke emission from diesel engines for non road mobile machinery in use". In the future, non road mobile machinery with substandard exhaust is prohibited from being used in construction sites, factories, ports and wharves in Shenzhen

rectification is not just a matter of Shenzhen

the rectification of paint is not just a matter of Shenzhen. To effectively stop the harm caused by paint, we need to adopt advanced DSCC ⑴ full digital closed-loop control system to control and measure the group from many aspects and angles, all departments and main machines

for coating enterprises: there are also many foreign experiences to learn from for the treatment of pollution in the coating industry. According to Yang Yuande, Secretary General of China Paint Industry Association, the United States and Germany implement an end push back method, that is, the government has a standard for VOC emissions in enterprise coating, and if it exceeds it, it will be punished, and the cost will finally be borne by the paint manufacturers. For example, automobile manufacturers will put forward the standard of volatile organic matter content to coating manufacturers. If it exceeds the standard, it will require to reduce the corresponding price. If it exceeds the limit, it will not be used again, which will force coating manufacturers to produce coatings that meet the standard. Yang Yuande said, "the key is to introduce the market mechanism, let the market guide the industry, and realize the win-win situation of pollution control and industry development." What coating enterprises can do is to actively respond, promote the transformation of industrial structure, continue to develop low VOC environment-friendly coating water paint, and guide the healthy and sustainable development of the coating industry

for coating products: water paint is an upgraded product of traditional paint, which uses water as diluent and does not contain benzene, toluene, xylene and formaldehyde. Compared with traditional solvent based coatings, waterborne coatings can greatly reduce VOC emissions. It can not only effectively reduce the impact on the environment, but also help to reduce the incidence of occupational diseases. Experts suggest that the promotion of water paint should be restricted by force. In China, the environmental protection policies, environmental protection indicators and mandatory standard measures that support the development of water paint industry and restrict high pollution and high emission paint are not perfect. Experts suggested that the Chinese government should formulate mandatory VOC emission policies and gradually implement them in stages to limit the pollution of oily paint. At the same time, we should encourage and support the development of the water paint industry, give preferential treatment and support in terms of Taxation and industrial layout, guide the paint industry to develop in a green and clean direction, and promote the technological innovation and industrial upgrading of the water paint industry

national policies: adjust and withdraw from polluting enterprises, formulate stricter industrial emission standards, implement the new sewage charge standards, and strengthen the collection of sewage charges from polluting enterprises. Implement differential electricity prices, punitive electricity prices, and differential water prices for polluting industries and enterprises, increase the production and operation costs of polluting enterprises, and promote the adjustment and exit of polluting enterprises. The application of water paint is an inevitable trend. The State formulates pollution discharge policies to restrict polluting paint. At the same time, it encourages and supports the development of water paint industry, gives preferential treatment and support in terms of Taxation and industrial layout, guides the paint industry to develop in a green and clean direction, and promotes the technological innovation and industrial upgrading of water paint industry

for the masses: we should clearly understand the harm of paint to people's health, understand the knowledge of paint, and learn to distinguish environmental friendly paint. When choosing paint for home decoration, try to choose water-based paint as much as possible, and don't choose it at will because of its low price. Start from everyone around you and resist the use of fake and inferior paint, so that polluting paint can take root everywhere
