[China paint information] Beijing furniture production enterprises all "oil to water". Since last year, furniture manufacturers in Beijing have fully realized or started the work of "changing oil to water". One year later, Beijing issued what is known as the strictest furniture pollutant emission standard in China. According to specific regulations, the furniture manufacturing industry in Beijing will completely ban the use of oily coatings after 2017, that is, to meet the use requirements of consumers for paint spraying. It is reported that one of the main purposes of formulating the new emission standards is to promote Beijing local furniture enterprises to replace all organic solvent coatings (oily coatings) used in furniture and other wood products with water-based coatings, and enterprises that do not replace them will completely withdraw from the market. In order to promote energy conservation and environmental protection, as early as January 26 this year, the Ministry of Finance and the State Administration of Taxation jointly issued the "notice on Levying consumption tax on coatings": with the approval of the State Council, consumption tax will be levied on coatings nationwide from February 1, 2015, including production, entrusted processing and import, with the applicable tax rate of 4%. At the same time, consumption tax is exempted for coatings with volatile organic compounds (VOC) content less than 420 g/L (including) under construction. These two environmental protection policies directly aim at the current serious pollution phenomenon in the two major industries of coating and furniture, strictly control the damage of load sensors in the upstream and downstream industrial chains, and implement two hands, so as to expand the application range of water-based coatings in industrial coatings
the "oil to water" of furniture industry is of great significance. Volatile organic compounds (VOC) emission is one of the important sources of PM2.5 generation. Data show that 18% of volatile organic compounds are produced by traditional solvent based paint emissions. The VOC emission of water-based wood paint accounts for only about one tenth of the emission of oil-based paint. According to the monitoring data, after Qumei furniture changed to water-based wood paint last year, the VOC emission of oil-based paint should be directly reduced by about 90%. Due to the stricter requirements on technology and production process and higher cost of water-based paint, the popularity of water-based paint in China is low at present. According to industry professionals, since the 1940s, foreign water-based coating technology has gradually developed and matured, and it has been applied to woodwork. By 1980, water-based coating was officially commercialized in Denmark. In China, the industrialization of waterborne wood paint has been difficult. From the rise of water-based wood coatings to the present, the first well-known coating enterprises in China have been difficult to become big. In 1995, because the core material of composite materials has not been tested, German Dufang paint was the first to enter the Chinese market and promote its mature brand of water-based Wood Coatings in Europe. Although the product has good environmental protection performance, due to its high price and the general environment for the application of water-based paint in China has not yet formed, the product is acclimatized. In 1996, Shandong yalimei company became the first domestic enterprise to produce waterborne wood coatings, but it declined in 2000
Shenzhen Qibao Chemical Co., Ltd. rushed into the water-based paint market in 2003, saying that the product solved the quality and cost problems of water-based paint, but up to now, the market reaction is general. According to the relevant person in charge of the Beijing Furniture Industry Association, the equipment renovation work of the production-oriented member enterprises registered in the association has been carried out successively. Qumei furniture has fully implemented the "oil to water" project last year, and the top 100 furniture has completed the "oil to water" project. Large and medium-sized enterprises such as Ronglin and liming Wenyi are actively implementing it. Due to the different effects of water-based coatings on different furniture, continuous experiments and tests are needed to adjust to the best gloss. The most fundamental problem is that enterprises must also transform and introduce production lines. According to renshuqin, vice president and Secretary General of the association, some enterprises are relocating based on cost considerations. Has the situation of "oil for water" been opened? Facing the strict VOC emission standards and the stricter requirements of the second stage of standard implementation, Beijing production-oriented furniture enterprises urgently need to transform the original production process. For production-oriented furniture enterprises, the cost of using water-based paint is 30% higher than that of using traditional oil-based paint, even as high as 50%. Tanchunlei, a paint expert, said, "the high cost of using water-based wood paint, high painting requirements and difficult production line transformation are the reasons why most furniture enterprises are unwilling to use water-based wood paint. The main sample materials are metal and non-metal."
relevant data show that at present, less than 15% of furniture manufacturers in the industry use water-based paint. At present, more than half of the more than 1000 furniture manufacturing enterprises in Beijing are still using oil-based paint spraying, and the comprehensive replacement of water-based paint will increase the production cost of enterprises to a certain extent. It is reported that relevant departments have included such technological transformation into the scope of technological transformation bonus support. The implementation of the new standard is not only a major test for the coating industry, but also a rare opportunity. It is understood that at present, there are not a few paint enterprises that also do water-based paint in the market. However, due to the limitation of market demand, there are not many large-scale applications for wood product spraying. Then, driven by the policy, the market demand for water-based paint is bound to increase significantly. Will the situation of water-based paint replacing oil-based paint be opened? According to insiders, "Beijing furniture manufacturing enterprises, Qumei and Ruichi have been transformed, Kebao and Tata have also been transformed, and many enterprises are in the preparation stage." In addition, cabinets and wooden doors are also within the scope of the emission standards for wooden furniture in Beijing. The insiders also said, "it takes at least twoorthree months for enterprises to change oil-based paint to water-based paint, and some take more than half a year. This is related to the transformation scale of enterprises, the transformation conditions of existing factories, the progress control of enterprises and other factors."
last year, when Zhao Ruihai, the head of Qumei furniture, announced that the enterprise would use water-based paint throughout the line, he said that the biggest challenge for enterprises to use water-based wood paint was technical problems. It took nearly two years to prepare for the transformation of Qumei furniture, Zhao Ruihai said, "First, we need to find out the production process flow, and ask 8 to 10 painters to find the water-based wood paint that is most suitable for Qumei products. Because we also need to consider the technical cost, we don't have three or four months to demonstrate clearly at all. Then, it takes at least three months to buy equipment and build production workshops. If enterprises want to use imported equipment, it takes at least half a year. Next, it takes another three months to put equipment into production Months. " Zhao Ruihai said that these products cannot be put into large-scale production immediately, because they should be sampled and revisited before being launched into the market to ensure that there will be no problems with the water-based paint process. "Oil to water" enterprises have difficulty digesting costs. Wood paint is used on wood products such as solid wood boards, wood grain panels, plywood, fiberboard, etc. it can be divided into water-based paint and oil-based paint according to product types. As a wood paint belonging to the category of industrial coatings, industrial coatings can be divided into water-based coatings, solvent based coatings and powder coatings at present. Among them, solvent based coatings still occupy the leading position in the global industrial coating technology, and the proportion reaches more than 75% of the total. With Beijing as the pilot, driven by policies, the era of water-based paint has arrived. In the next few years, oil-based paint will completely withdraw from the market and be replaced by water-based paint with low carbon, energy-saving, non combustible, non explosive and ultra-low emission, which uses water as diluent and does not contain organic solvents
at present, not only in China, but also in other countries, relevant laws and regulations on reducing VOC emissions are also being introduced, in which water-based coatings play an important role. Furniture manufacturing enterprises "oil to water", how to digest the increased cost, has become an important problem faced by enterprises. The increased cost is mainly reflected in the recycling of water-based coatings in the spraying process. Large enterprises can basically solve the problem by purchasing spraying machines with funds, while small enterprises are relatively laborious. For a long time, water-based paint is considered to be inferior to paint in high temperature resistance and hardness. However, paint experts said that this is not impossible to solve. Moderately increasing the cost on the panel of similar tables (table decoration effect drawing) is enough to make up for the lack of heat resistance of water-based paint. After all, there are no such problems in wardrobes and wooden beds, and they should be treated differently in terms of cost. With regard to "changing oil to water", Xiao Min, head of Beijing Liming Wenyi furniture, said that the enterprise is in the experimental stage of turning from small batch to mass production, mainly to solve technical problems. "During the period when the new standard was issued, the enterprise has been bidding and is currently doing product stability experiments with several water-based paint brands." Xiao Min said, "it is a huge and complex project to change all the assembly lines into water-based paint. The whole process structure needs to be changed, and the power needs to be changed as well. The equipment and plant reconstruction alone has made a budget of 40 million yuan, and more than 10 million yuan has been spent at present."
