The hottest VOC management regulations in Shenzhen

  • Detail

Shenzhen VOC management regulations will speed up the hydration process of furniture coatings

it seems to have become a routine to control air pollution before each large-scale sports meeting and ensure the air quality during the competition. Before the Beijing Olympic Games, there were rumors that the oily paint was off the shelves. During the Guangzhou Asian Games last year, Guangzhou issued the "plan for air quality assurance measures during the Asian Games in Guangdong Province", requiring "to stop all civil emissions of volatile organic compounds such as decoration and painting", and requiring "enterprises listed in the key regulatory list of volatile organic compounds emissions" to control the emission of organic gases, otherwise they will be "suspended". If the focus of these policies is to close and stop in the short term, the measures launched by Shenzhen on March 1 this year to rectify the pollution of volatile organic compounds in the air for the Universiade is a breakthrough management framework. This is the first time that China has used government actions to promote the upgrading of furniture coating industry structure to environmental protection and water-based, and fundamentally solve the problem of VOC air pollution. If the measures of Shenzhen can be successfully implemented, it will not only have a great impact on the furniture industry and coating industry in Shenzhen, but also have far-reaching significance for the national air volatile organic compounds pollution management and the national furniture coating industry

breakthrough in the management of volatile organic compounds in Shenzhen

according to the introduction of Shenzhen human settlements and Environment Commission, the main policies issued in Shenzhen in March include:

1) VOC emission polluting enterprises should consolidate and rectify all coating production lines before March 15

2) before April 30, all enterprises should declare the type, quantity, concentration and other emission of atmospheric pollutants to the environmental department in their jurisdiction, and provide air pollution control plans

3) the environmental protection department will, according to the enterprise's pollutant discharge declaration, the application for pollutant discharge license and the pollution discharge monitoring report, handle the pollutant discharge license for the enterprises that meet the standard before July 31, and issue a rectification notice within a time limit to the enterprises that exceed the VOC emission standard

4) the environmental protection department will punish the enterprises that fail to declare the pollution discharge within the time limit or fail to apply for (change) the pollution discharge license and continue to discharge VOC pollution within the specified time limit, and order them to stop production or business if the pollution is serious

although these regulations in Shenzhen are much similar to the previous "plan for air quality assurance measures during the Asian Games in Guangdong Province", a detailed analysis shows that Shenzhen's VOC emission management has some leading thinking of "China first". For example:

subdivisional Management: the VOC source pollution control measures for the Asian Games are to "stop all civil emissions of volatile organic compounds such as decoration and painting". For example, in Dongguan, printing, furniture production and automobile repair are required to be closed between October 20 and December 20. But Shenzhen is different. Shenzhen has clearly positioned the management of VOC emission reduction in furniture enterprises, because more than 2700 furniture enterprises have been registered in Shenzhen, ranking first in the country. The coating process of furniture manufacturing industry accounts for 49.4% of the annual emission of Shenzhen. Positioning the control object in the furniture manufacturing industry makes the VOC emission reduction management in Shenzhen not one size fits all, but targeted, which increases the scientificity and effectiveness of the policy

clear policy guidance: according to the requirements of Shenzhen human settlements and Environment Commission, industries or enterprises that can be transformed should be forcibly transformed according to different processes. Furniture enterprises listed in the list of compulsory rectification must change 50% of their coating production lines to water-based paint or UV paint before July 31 this year. This is the most groundbreaking regulation in Shenzhen this time. Just as switching off and limiting power cannot solve the problem of energy conservation, closing paint enterprises for a short time cannot bring blue skies and white clouds in the long run. "50% of the coating production lines in Shenzhen use water-based paint or UV paint" is the first time in China to link VOC emission management with the promotion of water-based paint and UV paint, trying to solve VOC emissions from the source, with clear policy guidance

government subsidies: "for enterprises that switch to water-based coatings or UV coatings on schedule, the municipal government will give 25% financial subsidies according to relevant regulations." It is a very special section of Shenzhen VOC management regulations. Generally speaking, among sticks and carrots, the previous regulations were mostly sticks, while Shenzhen increased its support for enterprises through subsidies on the basis of "closing, stopping and transferring"

of course, there are still some details to be discussed in Shenzhen's VOC management. For example, the development of water-based paint for furniture manufacturers needs time to develop and test, which can not be completed in a short time. " The feasibility of the "July 31" time limit is worth discussing with furniture manufacturers

half a year ago, the author wrote an article in Chinese furniture materials, (), pointing out that the development of water-based paint must be through three links: market demand, legislation and legislation to promote market development. In order to achieve marketization of water-based coatings in China, it must be clearly legislated by the government. In the absence of government legislation, the low popularity of water-based paint in the Chinese market is an inevitable result. Although it is not government legislation to drive supporting downstream industries, Shenzhen's VOC regulation is the first time that China has passed Jin min we work. It only took less than a year for the government to promote the transformation of the coating industry to water-based coatings and UV coatings, so as to control VOC and air pollution. The breakthrough of thinking in VOC management of Shenzhen human settlements and Environment Commission deserves the attention of China's coating industry

how should Shenzhen furniture enterprises deal with the latest VOC emission control policies

although the conversion of oily coatings to water-based coatings has been a hot topic in the furniture coating industry for many years, according to the observation of huajinsi company in the United States, there are still few furniture enterprises that really switch from oily coatings to water-based coatings, while most enterprises are in a wait-and-see state. Strict VOC management in Shenzhen will force 2700 furniture enterprises in Shenzhen to seriously consider the problem of coating hydration. For these enterprises, we can focus on the following three points:

1) carefully evaluate the performance requirements of coatings and determine the standards for the development of water-based coatings products: when determining the performance standards of water-based coatings, we must not directly use the performance of oil-based paints. Equating the performance of water-based coatings with that of oil-based coatings is still a topic all over the world, but this has not prevented water-based coatings from accounting for 37.8% of the total sales volume of the U.S. paint market in 2008

2) looking for technical cooperation to make up for their own shortcomings: cooperate with coating enterprises or coating raw material enterprises with water-based coating development experience to make up for their own deficiencies in water-based coating research and development with the help of the experience of suppliers

3) flexibly provide solutions while taking a long-term view. Using a full set of high-quality water-based coatings in furniture production to reduce VOC emissions is the goal of furniture coatings and furniture factories. However, the R & D and production conversion of water-based paint will take time. Within the time specified in the policy. Furniture manufacturers may wish to consider the solution of "water-based bottom, oil-based surface". In the process of furniture painting, the general process is four coats of primer and one coat of finish paint. Changing the primer to water-based can significantly reduce VOC emissions without affecting the overall coating effect. In recent years, huajinsi company of the United States has cooperated with many wood coating manufacturers whose prices are temporarily stable to promote the solution of "water-based base, oil-based surface", and achieved good results. This can not only reduce VOC emissions in a relatively short time, but also enable paint manufacturers and furniture manufacturers to gradually become familiar with water-based coatings and increase confidence in the transformation to water-based bottom and surface

the hydration of Chinese coatings will be a long-term process. The latest VOC management regulations of Shenzhen human settlements and Environment Commission is a breakthrough. In the coming months, the management policies of Shenzhen and the reflection of Shenzhen furniture industry will deserve the attention of the national coating industry
