Coating standard: Tianjin has issued and implemented mandatory VOCs standards for 11 key industries such as coating

Core tip: Tianjin Environmental Protection Bureau and Tianjin market and quality supervision and Management Committee jointly issued the mandatory local standard "emission control standard of volatile organic compounds for industrial enterprises" (hereinafter referred to as "the standard") According to the relevant person in charge, this is the first comprehensive standard covering the volatile organic compounds (VOCs) emission industry of industrial enterprises in China The standard specifies petroleum refining and petrochemical, pharmaceutical manufacturing, rubber product manufacturing, coating and ink production, plastic product manufacturing, electronic industry, automobile manufacturing and maintenance, printing and packaging printing, furniture manufacturing, surface coating, ferrous metal Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings news: Tianjin Environmental Protection Bureau and Tianjin market and quality supervision and management committee recently jointly issued the mandatory local standard "emission control standard for volatile organic compounds of industrial enterprises" (hereinafter referred to as "the standard") According to the relevant person in charge, this is the first comprehensive standard covering the volatile organic compounds (VOCs) emission industry of industrial enterprises in China The standard specifies petroleum refining and petrochemistry, pharmaceutical manufacturing, rubber product manufacturing, paint and ink production, plastic product manufacturing, electronic industry, automobile manufacturing and maintenance, printing and packaging printing, furniture 11 key industries of manufacturing, surface coating, ferrous metal smelting, and other industries VOCs organized emission concentration and rate limit, unorganized leakage and emission pollution control requirements, plant boundary monitoring point concentration limit, management regulations and monitoring requirements According to the standard, enterprises with an hourly emission of more than 2.5kg or an exhaust volume of more than 60000 m3 / h must install online monitoring facilities Huang Haoyun, director of Environmental Planning Research Office of Tianjin Academy of Environmental Sciences and director of Tianjin Key Laboratory of air pollution prevention and control, introduced that the subject of standard formulation was established in March 2012, which solved the problems of standard type and positioning, selection of control factors, determination principles of standard limits and monitoring methods Based on the analysis of the emission status, treatment status and technical and economic level of each industry, and according to the ambient air quality status and recent improvement objectives of Tianjin, the VOCs emission limits of each industry are formulated In order to reserve a certain buffer time for the equipment installation and technical transformation of existing enterprises, the standard is divided into two periods, the first period is from August 1, 2014 to December 31, 2015, and the second period is from January 1, 2016 The standard of the second period is stricter than that of the first period The newly-built enterprises shall directly follow the second period standard "On the whole, after the implementation of the second period standard, this standard is slightly stricter than the existing corresponding standards of China, the European Union, the United States and Japan." Huang said Why does Tianjin develop such a comprehensive standard covering VOCs emission industry of industrial enterprises? According to the requirements of action plan for air pollution prevention and control, detailed rules for implementation of action plan for air pollution prevention and control in Beijing, Tianjin, Hebei and surrounding areas and the 12th Five Year Plan for air pollution prevention and control in key areas, by 2015, Tianjin The total VOCs emissions from active sources need to be reduced by 18% VOCs come from a wide range of sources Tianjin, as an advanced manufacturing area, is a relatively concentrated area of VOCs emissions In order to promote the regional air pollution control under the new situation, it is an urgent task for Tianjin to formulate a comprehensive local standard covering the VOCs emission industry of industrial enterprises before the national standard is issued The promulgation of the standard provides further guarantee for the realization of the reduction target and the continuous improvement of environmental quality According to the introduction of relevant experts from the Key Laboratory of atmospheric science, Tianjin Academy of Environmental Sciences, according to the accounting of Tianjin pollution source census database enterprises in 2010, the annual emission of industrial VOCs in Tianjin is about 230000 tons, and the secondary fine particles generated from this contribute a lot to the emission of PM10, PM2.5 and other fine particles This expert believes that the implementation of the standard is of great significance for VOCs Pollution Control of industrial enterprises in Tianjin Experts in the industry believe that after the implementation of the standard, industrial VOCs waste gas will be included in daily environmental supervision like conventional pollutants such as particulate matter, sulfur dioxide, nitrogen oxide, etc., providing important technical support for environmental management in Tianjin At the same time, to promote the total emission reduction of VOCs will also play a role in effectively controlling PM2.5 and ozone pollution in the city It is understood that in order to promote the implementation of the standard and standardize the management of VOCs unorganized emissions, Tianjin will study and formulate the VOCs unorganized emissions management standard system, further refine the management requirements, and prevent and control VOCs unorganized emissions Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
