Beijing-tianjin-hebei First Environmental Protection Unified Standard Implementation VOCs Governance Sword Refers To Paint

- Sep 28, 2017-

On September 1, the standard for the content of volatile organic compounds in building coatings and adhesives issued by beijing-tianjin-hebei province was officially implemented. In the paint industry "golden nine silver ten", the implementation of the standard, or will put the high VOCs content of paint on the road.

Since last year, according to the tianjin environmental protection bureau staff, qiu dong season, appear in numerous weather, heavy pollution not only affects large range, and the pollution degree of heavy, long duration, become residents of beijing-tianjin-hebei region "heart and lung of". However, smog and ozone and other harsh atmospheric environment can not be separated from the infamous VOCs. The coating industry is an important source for the emission of VOCs in China, which is a great scourge of air pollution.

As the first unified environmental protection standard in beijing-tianjin-hebei province, the standard for the content of volatile organic compounds in building coatings and adhesives is directed at architectural paints. Construction paints are not only used in large quantities, but also in the open air when used. VOCs are not treated directly in the atmosphere. In winter, these VOCs mixed with materials such as sulfur dioxide and dust, forming a frenzy of fog, in the summer, under the sun, through a series of photochemical reaction and the ubiquity of ozone overweight problem.

It is understood that foreign countries have long ago limited the VOCs content in decoration materials such as paint. And the development of the standard for coating VOCs in China is only just starting, and the standard is relatively loose compared with developed countries in Europe and the United States. In addition, the high proportion of paint use in China is also an important reason for the high emission of VOCs in the coating industry. By comparison, the proportion of water paint in Europe and the United States has reached 80% to 90%.

However, the effects of VOCs in paint are not limited to air pollution. Studies have shown that the paint because contain toxic substances such as formaldehyde, benzene, lead, when they are with VOCs evaporate into the air, the people in the nearby environment, there will be a headache, dizziness, cough, the phenomenon such as nausea, vomiting, and easy to acute poisoning. So, because of poor health and safety awareness, construction workers have been poisoned during construction, and even deaths have occurred.

According to the environmental protection bureau, the standard not only defines test methods and inspection rules, but also provides a basis for the detection of VOCs in the environment. We also put forward packing mark requirements for coating products and guide consumers to choose low VOCs content products. The most important thing is that it requires that the limit value of the coating VOCs should not be produced and used. This provides support for the supervision of the upstream and downstream industry of coatings, and will control environmental pollution from the source.

It is understood that the standards since September 1 synchronous implementation, by reviewing the production, the sale, use construction coating and adhesive each link in the whole process control, a conservative estimate would reduce VOCs emissions by more than 20%. This means that in the beijing-tianjin-hebei building coating area, the paint of high VOCs content will gradually face the situation of being eliminated completely.
