Common knowledge of paint: the problem of drying water-based paint is overcome, furniture is expected to be more environmentally friendly

Core tip: water based paint is more environmentally friendly than oil-based paint, which has been deeply rooted in people's minds With the national and social attention to environmental protection, the oil paint with poor environmental protection is gradually replaced by water paint At present, the field of wall paint is almost the world of water-based paint However, furniture, another major source of home decoration pollution, is rarely applied with water-based paint Waterborne paint is more environmentally friendly, but less used in furniture "The emission of harmful substances in furniture paint in China is 303 times higher than that in European standards ” Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: water paint is more environmentally friendly than oil paint, this concept has been deeply rooted in the people's minds With the national and social attention to environmental protection, the oil paint with poor environmental protection is gradually replaced by water paint At present, the field of wall paint is almost the world of water-based paint However, furniture, another major source of home decoration pollution, is rarely applied with water-based paint Water based paint is more environmentally friendly, but it is less used in furniture "The emission of harmful substances in furniture paint in China is 303 times higher than that in European standards." Yao Ruoling, deputy general manager of Changjiang furniture in Shenzhen, said at the furniture drying technology development forum held recently that although waterborne paint has been widely used in the paint field, it has not been widely used in furniture paint According to a survey conducted by Beijing Furniture Association in 2012, the proportion of waterborne wood paint in furniture industry is only 8.3%, far lower than that in Europe and the United States, which is more than 60% Water based paint is a kind of environmental protection paint, which uses water as diluent and does not contain organic solvent The coating does not contain benzene, toluene, xylene, formaldehyde, free TDI toxic heavy metals, non-toxic and non irritating smell, harmless to human body, and does not pollute the environment Qu Jinqing, a professor at South China University of technology, said that more than 50% of the traditional oil paint is organic solvent, which will release harmful gases into the atmosphere during the construction process and bring pollution to the environment Due to the environmental protection of water-based paint, in recent years, the topic of "oil" to "water" in furniture paint has been hotly discussed in the industry The state also strongly supports the development of waterborne paint, and has made adjustments in many policies and regulations For example, the consumption tax and emission tax of VOC of oil paint are levied, and the emission of furniture factory is regulated Beijing requires all oil furniture factories to move out before 2016, and Shenzhen has introduced relevant restrictions Yang Xian, President of China water based paint technology alliance, said in his speech that water based paint is beneficial to the country and the people, and the government will definitely actively support it At present, water-based paint has entered many local government procurement lists, and has been designated as a product by many large-scale events and activities Driven by this environment, water-based furniture paint will become the mainstream in the future High cost, difficult construction and concept deviation are stumbling blocks Although water-based paint is a more environmentally friendly material for furniture, its promotion in China is relatively slow According to the analysis of participants in the industry, problems such as lack of relevant standards, high cost and difficult construction are obstacles to the development of water-based paint First of all, the slow drying is the biggest problem of waterborne paint, the traditional way of hot air plus infrared drying is slow, and the drying of waterborne paint is also affected by weather factors In the south of China, where there is abundant rainfall, it is difficult to dry the waterborne paint Moreover, the high cost of using water-based paint is also a major reason to prevent small and medium-sized enterprises from using water-based paint In addition, the wear resistance and brightness of water-based paint are difficult to match with the traditional "paint" at present Domestic consumption habits like bright, rich and thick paint surface To achieve this effect, water-based paint needs higher cost and more complex process Most furniture companies prefer to use relatively simple operation, mature technology, but also to meet consumer preferences Microwave infrared coupling technology to solve the problem of hard drying of water-based paint is recognized as the key to promote the drying of furniture water-based paint in the industry At present, there are new methods to overcome this technical problem In this forum, Carpoly first launched "microwave infrared coupling technology", which is expected to promote the development of waterborne furniture paint According to Zhu Yan'an, general manager of the waterborne paint business department of Carpoly, microwave infrared drying means that water is completely evaporated through microwave and infrared radiation The heat transfer efficiency of the technology is very high, which can instantly increase the temperature from inside to outside, and the heating is balanced, so as to avoid the phenomenon of whitening, mildew, cracking and so on Through this technology, the furniture paint on both sides of the bottom can be dried quickly in about an hour, and can be packaged directly If the traditional paint is used, the drying time should be at least 4 hours Microwave infrared drying technology effectively solves the bottleneck problem that restricts the development of the industry It is reported that more and more furniture enterprises have adopted water-based furniture paint, including IKEA, Shenzhen Changjiang furniture, Shenzhen colorful life children's furniture, Foshan Junye furniture and other well-known enterprises Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news
