Water-like paint instead of traditional paint is considered a future trend

China Paint Network
:
Beijing strictly control furniture production pollution emissions
at the time, environmental protection issues are becoming the furniture industry is facing a "big problem." Volatile organic matter released by the
passing
painting process in the furniture production process is one of the sources of atmospheric pollutants, and the draft of the Beijing municipal standard "The Standard for Atmospheric Pollutant Emissions in the Wood Furniture Manufacturing Industry", which is called "the most stringent in the world" by the industry, has been completed. Furniture enterprises have begun to carry out the transformation and upgrading of production links, the use of water-like paint instead of traditional
painting
, is also considered by the industry to solve the pollution of furniture production enterprises the fundamental way.
In 2014, the Beijing Municipal Environmental Protection Bureau announced the launch of 100 environmental protection technology reform projects, plans to implement more than 100 air pollution prevention and environmental protection technology reform projects, involving volatile organic matter control, desulfurization, denitrification, dust removal and other pollution elements of technical reform and control, through technological innovation to reduce pollutant emissions.
Since the start of 100 environmental protection technology reform projects, has now completed Qumei furniture water-color paint replacement project, Fukuda Daimler Motor Company two plant water-quality paint replacement project, Yanhua company Shunding rubber exhaust treatment project, such as the first phase of the key environmental protection technology reform projects.
that the focus of industrial emission reduction includes volatile organic compounds, nitrogen oxides, sulfur dioxide, soot and other atmospheric pollutants. The coating industry, which uses a lot of paint, including the furniture manufacturing industry, is an important source of VOCs pollutants.
Chunlei, secretary-general of the China Coatings Industry Association, said that the pollution caused by coatings to the environment comes not only from the paint itself, but also from the solvents used in the coatings. If VOCs are not properly treated, they are all evaporated into the atmosphere, causing pollution to the environment, and VOCs are also subject to chemical reactions by environmental factors that produce more toxic pollutants than the original, resulting in secondary contamination.
Zheng Rehong, deputy director of the Beijing Municipal Environmental Pollution Prevention and Control Department, revealed that the detailed standards for the emission of pollutants into the industry will be issued, furniture manufacturing, automobile manufacturing and other 7 industry pollutant emission standards are being revised. This means that the emission standards for pollutants in the furniture manufacturing industry are more detailed. Industry insiders judge that this standard will be the furniture production enterprises "tight spell", from the deployment of Beijing to clean up air pollution, refined to each industry requirements is inevitable, will also bring changes to the pattern of Beijing furniture production enterprises, furniture production enterprises environmental protection technology reform road has been imperative.
? According to industry insiders, at present, only a few enterprises in furniture production enterprises will collect VOCs, only individual enterprises will collect VOCs for processing and re-emissions, the vast majority of enterprises will BECS free release into the atmosphere.
to this, Zhu Changling, chairman of the China Furniture Association, said, "After the introduction of the standard, enterprises must be in accordance with the standards for rectification, if not up to standard, can only close the door, there is no room." "Industry analysis, the future industry pollutant emission standards or will be integrated throughout the country, when Beijing, Tianjin, Yangtze River Delta, Pearl River Delta region will carry out environmental protection technology reform. Moving the site to Hebei may be a stopgap measure, and the fundamental solution is to carry out environmental rectification.
is an important solution to reduce VOCs emissions in the production of furniture. Water-based paint is water-based thinner, organic solvent-free coating (containing only a small amount of ethanol), no benzene, formaldehyde (no one to add), free TDI (toluene diocyanate), toxic heavy metals, non-toxic non-irritating odor.
reported that the release ratio of VOCs of ordinary solvent-based coatings is about 50%, that is, 1 ton of solvent coatings will release about 500 kg of volatile harmful gases, some experts said that water-based paint VOCs emissions are about 1/10 of oily paint emissions, that is, 1 ton of water-based paint, VOCs emissions of about 50 kg. At present, water-based paint in the EU's main coating industry penetration rate is very high, is the future development of environmental protection is an inevitable trend.
according to industry insiders, the furniture production process VOCs emissions mainly come from the coating process, in the furniture coating process, coating and thinner VOCs will be in the form of gaseous emissions to the workshop environment. If VOCs in the shop floor environment are not collected and processed effectively, VOCs will be released into the outside atmosphere, which is why the furniture manufacturing industry can cause VOCs pollution. In the real production process, furniture manufacturing enterprises need to install collection facilities to collect VOCs, and then use end purification equipment to deal with VOCs, the cost of governance is relatively high.
developed countries in china, low VOCs paints are widely used instead of solvent-based coatings to control VOCs emissions from the furniture manufacturing industry at the source. Water-based paint as a low VOCs content of the coating, water as a solvent, compared with solvent-based coatings has obvious advantages, its popularization and application for the furniture manufacturing industry VOCs emissions provide a new way.
, vice president of the Beijing Furniture Association, said the Beijing Furniture Association had been concerned about promoting water-like paint in the furniture industry as early as 2012. At that time, the association selected more than 120 enterprises of scale to visit the survey, according to a sample survey, the use of water-based paint accounted for 8.3%. For now, the proportion of water-like paint used in the furniture industry has increased, about 15%. She said that in the study found that some manufacturers of water-like paint awareness is insufficient, that water-like paint in the color is not up to standard, hardness is not enough, and some enterprises worry about the cost of retrofitting production lines is too high.
industry also said that water-color paint products for consumers to accept it will take some time. On the issue of cost, experts said that the cost of water-based paint compared with ordinary paint, there is no question of who is high and who is low, water-based paint prices are also divided into several grades according to different products, therefore, absolutely speaking, water-based paint costs higher than ordinary paint costs is not scientific. If enterprises from the traditional ordinary paint production line into water-like paint production line, production processes and production equipment need to be modified, such as water-like paint on the drying conditions are high, enterprises need to add drying equipment when spraying, so that changes in the production process will certainly increase costs. Moreover, water-like paint products have a long drying time, and the reduction of production efficiency will also lead to higher production costs.
said that some people may think this is a blow to the traditional furniture manufacturing industry, and I think this is just an opportunity to promote the upgrading of the furniture industry. Each industry in the process of transformation and upgrading, will inevitably eliminate a number of backward production capacity through technological innovation, which is also the inevitable path of industry development. In some large enterprises to use water-like paint, consumers will be more aware of the benefits of water-like paint, naturally forced furniture manufacturers to use more environmentally friendly water-like paint, to meet consumer demand.
present, Beijing does not have specific standards for the furniture manufacturing industry pollutant emission requirements, but to comply with the "integrated emission standards of atmospheric pollutants" this unified standard. This standard sets emission limits for 33 types of atmospheric pollutants.
that? Industry insiders say the new standards will be more detailed. In addition to setting emission limits for atmospheric pollutants, the standards for the furniture manufacturing industry also require the properties, usage, production environment, production process and equipment production processes in the furniture production process. In terms of the specified value of atmospheric pollutants, in addition to limiting VOCs emissions, dust emissions will be limited, but also for the specific requirements of the industry characteristics.
industry also said that the current compliance with the "comprehensive emission standards of atmospheric pollutants" in the formulation, is in accordance with the EUROPEAN Union's international standards, it can be said that the standard limits have been in sync with the world level. After the introduction of the new standards, the furniture production industry will be more detailed environmental requirements, promote the transformation and upgrading of the industry, to make a positive contribution to environmental protection.
