    News: With the spread of haze weather, from PM2.5 to car formaldehyde exceeding the standard, from water pollution to industrial exhaust gas, the outside world can not fight environmental pollution so that consumer demand for healthy homes more and more strong, the "environmental protection of human living" voice is getting higher and higher. How can home decoration not only protect the physical and mental health of the family, but also create a comfortable, beautiful, personalized healthy home?
    July 1, Shenzhen city completely banned the serious harm to the health of the public solvent-based
    coatings
    (
    paint
    ), adhesive and other unqualified decoration materials, become the first in the country to limit the sale and use of solvent-based coatings (paints) city. On the same day, Beijing for the furniture manufacturing industry is currently the most stringent local environmental standards , "wood furniture manufacturing industry atmospheric pollutant emission standards" also officially implemented.
    an unprecedented environmental storm, which also caused a reverberation at the just-closed Guangzhou Construction Expo. Under the sky, people use what materials for decoration more environmentally friendly thinking, green building materials worthy of attention to which?
    the last two years, new green building materials of all types have become richer, more selective and have a variety of conceptual functions.
    is the raw material for the production of furniture, in the home decoration, especially small flowers, wall modeling applications are also very wide.
    "the culprit" of smog weather is PM2.5, the main source of emissions, except for vehicle exhaust (30%) which is VOC emissions (21%). According to the data, about 18% of VOC emissions are generated by solvent-based coatings (paints). In order to achieve the goal of reducing PM2.5 to 33 micrograms/m3 in 2015, the Shenzhen Habitat Environment Commission said that the introduction of "building decoration coatings and adhesive hazardous substances limit" special zone technical specifications, July 1 to implement the second phase of hazardous substances limit standards, a total ban on solvent-based coatings (paints), adhesives and other unqualified decorative materials.
    as early as 2004, the European Union has legislated to prohibit the production and use of paint. Because paint not only pollutes the environment but also does great harm to human body. According to Yan Ankui, executive director of Guangzhou Architectural Decoration Industry Association, traditional paints tend to use a large number of toxic and harmful VOCs (volatile organic solvents) as thinners, and some products also use curing agents containing free TDI, resulting in a large amount of air pollution. The long-term inhalation of these solvents and curing agents of volatile gases, easy to lead to regenerative anemia, leukemia, tuberculosis, thoracicitis and other serious diseases.
    , before the "no paint order" was officially implemented, water-like paint has been the mainstream of interior decoration use. Its VOC emissions are only about 1/10 of paint. At this year's Guangzhou Jianbo, Jiabao professional waterproof brand dress appearance, to a half-person high fish tank raised tropical fish, glass and board seams using
    waterproof paint
    , image expression performance and environmental protection concept. And the same as
    water-based paint
    of the blue mansion played a "personality wall custom experts", to paint the art and crafts color, showing imitation stone, imitation wood, imitation landscape murals and other different texture of the coating effect.
    addition to water-based coatings,
    powder coatings represented by diatom
    are also a kind of environmentally friendly wall materials that have risen rapidly in recent years. Old listed enterprises Dajin diatom mud, this year on display adsorption formaldehyde capacity than charcoal five or six thousand times stronger than the new series. According to Niu Lijiang, general manager of Guangzhou Dajin Company, it is not only rich in texture, smoke and taste, dust, but also has the equivalent of wallpaper and mortar 2 to 3 times the humidity. On-site display of easy rolling construction of the inner wall products and good protection and effective resistance to saline erosion of the external wall products, but also a highlight of the eye.
    compared with the diatom mud moving 100 to 300 yuan / square meters of the price, this year's exhibition also appeared a cheaper product - a new type of paint made from shell powder processing. As the patent holder of this dry powder shell powder
    built-in wall coating
    , Zhang Wanxi, a professor in the Department of Polymer Materials and Engineering at Jilin University, told reporters that shell powder is prepared with deep sea shells as a substate, made from adhesives extracted from natural materials, in addition to its own pure natural non-polluting, but also absorbs harmful gases such as formaldehyde produced by decomposing interior decoration materials. Guangdong Yuguan biotechnology staff producing shell powder showed reporters a test report issued by the National Paint Product Quality Supervision and Inspection Center (Guangdong), which did not detect that the material sent for inspection contained free formaldehyde. In addition, one of its major features is the smooth coating of rapid construction, mass production prices can also be
    with
    latex paint.
    is the raw material for the production of furniture, in the home decoration, especially small flowers, wall modeling applications are also very wide. Before the media exposed formaldehyde, benzene exceeding the standard event, the source can even be traced back here. Starting from July 1, Beijing took the lead in the implementation of the most stringent local environmental protection standards, "wood furniture manufacturing industry atmospheric pollutant emission standards", the first time put forward to limit the volatile organic content of raw materials indicators, greatly reduced the wood furniture containing benzene, particulate matter, the maximum allowable emission concentration of the prescribed limits, and the process measures and management requirements.
    According to data released by the China Coatings Industry Association, China's paint coating industry emits about 4.3 million tons of VOC per year, of which oily paint accounts for about 98% and water-based paint accounts for about 2%. He Fa-yu, vice president of the Beijing Furniture Industry Association, said one of the main aims of the new emission standards was to encourage furniture manufacturers to choose water-based coatings. However, according to industry sources, the current
    water-like wood paint
    in the domestic furniture industry is far less popular than water-like wall paint, less than 15% of furniture manufacturers use water-like
    wood paint
    , is still not the mainstream of the market.
    , of course, environmentally friendly, from home only environmental health, there are a large number of board custom furniture on the market today. Water-based wood paint is only to solve the furniture surface coating, if the plate itself environmental performance is not up to standard, even if the use of water-based paint, after all, VOC discharge cycle up to ten years, so this is ultimately a family life in a health hazard. Moreover, according to the national standard "indoor air quality standards", testing is a closed space of harmful gases accumulated total, even if the environmental protection of a single piece of furniture, it does not necessarily represent health and safety.
    consumers' over-desire for environmental protection has forced tougher standards at home and prompted businesses to pursue the concept of zero formaldehyde. In this year's Guangzhou Construction Expo, the plate will no longer stay in the European standard E0 E1 or Japan F4 star standard, Huazhou Wood this year exhibited the world's first zero formaldehyde wood particle board, with long wood fiber, stable good, high strength advantages, while solving the traditional particle board thick loose, weak strength, poor grip strength of the drawbacks. According to Huazhou Wood Executive Vice President Yan Mingxing revealed that the plate using formaldehyde-free added U.S. MDI ecological adhesive, and the use of the world's most advanced German Diffenbach continuous press production line and continuous pressure mechanism version of the process, fully realized a new upgrade of homogeneous particle board. This in the plate performance and environmental protection index at the same time, but also ended the history of particle plate must release formaldehyde.
    , the concentration of negative oxygen ions in the air is a sign of fresh air or not. The Smike negative ion health board is a newly listed eco-building material affaked to the indoor small flower wall. Its biggest feature is like a forest in general, can release a large number of negative oxygen ions beneficial to human health, but also can eliminate smoke and dust, sterilization and mold prevention, remove formaldehyde, purifying the air, known as "no plug-in maintenance-free indoor air purifier." According to the person in charge of Chen Weixiong, the plate contains a permanent release of negative ions of the expansion of zircon, after installation can make the negative oxygen ion content of the family space from the original 10 to 50 / cubic centimeters to 1000 to 5000 / cubic centimeters.
    environmental protection is an eternal theme. This is not only in the field of paint, sheeting, but also the need for home decoration tiles. For example, this year's appearance of a microcrystalline, is an alternative to stone (stone decoration effect map) and ceramic new building materials, it is granite debris as raw materials, the use of high-tech production.
    Compared with ordinary stone, ceramics and other products, microcrystalline surface is more dense, colored, pure, high hardness, non-absorption and other advantages, its hardness and bend strength is twice that of marble, acid resistance is four times that of ordinary stone, alkaline resistance is twenty times that of ordinary stone, its radioactivity is four times better than international standards. Due to the consistent texture, it can bend the shape, but also to meet the hollow carving, color carving, repeated grinding and renovation needs. Can be customized according to shape, size, in addition to as a regular building materials, can also be made into screens (screen decoration effect map), murals and so on.
    addition, there is a clean haze self-cleaning coating applied to the exterior of the building, the active substance can be stimulated by sunlight and a photocatalytic reaction, can break down oily pollutants and some inorgable objects; At the same time, there is the elimination of static electricity, do not adsorption dust and other paint film anti-fouling, clean effect.
    undeniably, from the last two years, all types of green building materials new products than ever before more rich, more selective, conceptual functions are also a variety. More and more people advocate environmentally friendly decoration, for indoor air quality has a higher requirements, not only to consider beautiful, but also pay attention to health. In decoration, most people will try to use environmentally friendly decoration materials to minimize indoor pollution. However, there are still many details that deserve to be noted by consumers.
    First of all, in order to achieve true environmental protection, we need to pay attention not only to decoration materials, but also from the design to start greening up: design principles, design programs, construction procedures, decoration materials selection and indoor air quality inspection, etc. should be paid attention to. Guangzhou senior designer Peng Zheng believes that environmental protection decoration materials do not represent the indoor environment must meet the standards, consumers in the design to consider the housing unit area decoration materials the best use, but also to consider furniture, flooring and other products formaldehyde release overlay effect.
    , the choice of green materials can not just listen to one side of the word, should require sales staff to issue national mandatory standards of product quality inspection report. For example, different products to focus on the ring report indicators are also different, for example, board furniture focus on formaldehyde testing report, solid wood furniture focus on benzene detection report, solvent-based wood paint, adhesive focus on benzene, VOC test report.
    , choose the correct construction. Decoration is a huge project, must use the correct decoration process and process, such as plate after cutting, timely edge treatment; Wood products brush oil to be complete, it is best not to leak brush; Local decoration end timely pollution prevention and control, to minimize the release of harmful gases. Strictly speaking, pollution is almost inevitable throughout the renovation process, but it is not terrible. Conditional, it is recommended to find a CMA certified third-party agency for air testing before check-in.
