Common knowledge of paint: new paint will replace paint plate

Core tip: with the spread of haze weather, from PM2.5 to excessive automobile formaldehyde, from water pollution to industrial waste gas, the irresistible environmental pollution makes consumers' demand for healthy home more and more intense, and the voice for "environmental protection and human settlements" is higher and higher How can family decoration not only protect the physical and mental health of the family, but also create a comfortable, beautiful and personalized healthy home? Since July 1, Shenzhen has banned substandard decoration materials such as solvent based coatings (paints) and adhesives, which are seriously harmful to the health of citizens, Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings news: with the spread of haze weather, from PM2.5 to excessive automobile formaldehyde, from water pollution to industrial waste gas, the irresistible external environmental pollution makes consumers' demand for healthy home more and more strong, and the call for "environmental protection and human settlements" is higher and higher How can family decoration not only protect the physical and mental health of family members, but also create a comfortable, beautiful and personalized healthy home? Since July 1, Shenzhen has banned substandard decoration materials such as solvent based paint (paint) and adhesive, which are seriously harmful to the health of citizens, and has become the first City in China to restrict the sales and use of solvent based paint (paint) On the same day, Beijing's most stringent local environmental protection standard, emission standard of air pollutants for wood furniture manufacturing industry, was officially implemented The unprecedented environmental protection storm also triggered a response at the just concluded Guangzhou Construction Expo Under the sky, people have pondered over what materials are more environmentally friendly for decoration, and what green building materials are worth paying attention to? In recent two years, new types of green building materials are more abundant, more selective and have various conceptual functions Board is the raw material of furniture production It is also widely used in home decoration, especially in ceiling and wall modeling PM2.5 is the main source of PM2.5, which will replace paint haze In addition to vehicle exhaust (30%) is VOC emission (21%) According to the data, about 18% of VOC emissions are generated by solvent based paint (paint) emissions In order to achieve the goal of reducing PM2.5 to 33 μ g / m3 in 2015, the Shenzhen Municipal Commission of human settlements and environment said that it had issued the special zone technical specifications for the limit of harmful substances in building decoration coatings and adhesives, implemented the limit standard of harmful substances in the second stage from July 1, and banned unqualified decoration materials such as soluble coatings (paints) and adhesives As early as 2004, the European Union had legislated against the production and use of paints Because paint not only pollutes the environment but also does great harm to human body According to Ni Ankui, executive director of Guangzhou construction and decoration industry association, a large number of toxic and harmful VOCs (volatile organic solvents) are often used as diluents in traditional paints, and some products also use curing agents containing free TDI, resulting in a large number of air pollution The long-term inhalation of these solvents and curing agent volatile gas, easily lead to aplastic anemia, leukemia, tuberculosis, pleurisy and other serious diseases In fact, before the official implementation of the "no paint order", water-based paint has been the mainstream of interior decoration Its VOC emission is only about 1 / 10 of that of paint At this year's Guangzhou Construction Expo, the professional waterproof brand of cabaret appeared in full dress The tropical fish was raised in a half person high fish tank The joint between glass and wood board was made of waterproof coating, which vividly expressed the concept of performance and environmental protection While the same as the water-based paint, the enamel residence has played the "personalized wall customization expert" to paint the color art process enamel color, showing the painting effect of different texture, such as imitation stone pattern, imitation wood pattern, imitation landscape mural, etc In addition to the water-based coating, the powder coating, represented by diatom mud, is also a kind of environmental protection wall material rising rapidly in recent years Dajin diatom mud, an old listed company, has exhibited a new series of products with the ability to absorb formaldehyde five or six thousand times stronger than charcoal this year According to Niu Lijiang, general manager of Guangzhou Dajin company, in addition to its rich texture, smoke elimination and odor elimination, and dust free, it also has the humidity regulating property equivalent to 2-3 times that of wallpaper and mortar The on-site display of the interior wall products that can be simply rolled and coated and the exterior wall products that have good protective performance and can effectively resist the salt and alkali erosion are also a bright spot Compared with the selling price of diatom mud of 100-300 yuan per square meter, this year's exhibition also saw a cheaper product - a new coating made of shell powder As the patent holder of the dry powder shell powder interior wall coating, Professor Zhang Wanxi of the Department of polymer materials and engineering of Jilin University told reporters that the shell powder is made of the deep sea shell as the substrate and the adhesive refined from the natural materials In addition to its pure nature and pollution-free, it can also absorb and decompose harmful gases such as formaldehyde produced by the interior decoration materials Guangdong Youguan biotechnology staff, who produces shell powder, presented a test report issued by the national coating product quality supervision and Inspection Center (Guangdong), but no free formaldehyde was detected in the materials submitted for inspection In addition, it is a major feature of flat coating rapid construction, mass production price can also be combined with latex paint Plate: the environmental protection function is more prominent Plate is the raw material of furniture production It is also widely used in home decoration, especially in ceiling and wall modeling Before the media exposure of formaldehyde, benzene exceeding the standard, the source can even be traced back to this Since July 1, Beijing has taken the lead in implementing the most stringent local environmental protection standard emission standard of air pollutants for wood furniture manufacturing industry in China For the first time, it has proposed to limit the content of volatile organic compounds in raw and auxiliary materials, greatly reducing the maximum allowable emission concentration of benzene and particulate matter contained in wood furniture, and has also proposed regulations on process measures and management requirements Fixed According to the data released by China Coating Industry Association, the total VOC emitted by China coating industry is about 4.3 million tons per year, of which the proportion of oil paint is about 98% and that of water paint is about 2% He fajian, vice president of Beijing Furniture Industry Association, said that one of the main purposes of the new emission standards is to promote furniture manufacturers to choose water-based coatings However, according to industry insiders, at present, waterborne wood paint is far less popular in domestic furniture industry than waterborne wall paint, and only less than 15% of furniture manufacturers use waterborne wood paint, which is still not the mainstream of the market Of course, regardless of the environmental friendliness, only from home environmental protection and health, there are a large number of plate type customized furniture on the market today Water based wood paint only solves the problem of furniture surface coating If the environmental protection performance of the board is not up to standard, even if water-based paint is used, after all, the VOC emission cycle can be as long as ten years, so it is ultimately a health hazard in family life Moreover, according to the national standard indoor air quality standard, the total amount of harmful gases in a confined space is detected Even if the environmental protection of a single piece of furniture reaches the standard, it may not represent health and safety The excessive desire of consumers for environmental protection has forced domestic implementation of more stringent standards, and also prompted businesses to pursue the concept of zero formaldehyde At this year's Guangzhou Construction Expo, the board will no longer stay in the European standard of E0 grade E1 or Japanese F4 star standard Huazhou wood industry will exhibit the world's first zero formaldehyde log particle board this year, which has the advantages of long, stable and high strength wood fiber, and solves the disadvantages of the traditional particleboard, such as bulkiness, looseness, weak strength and poor nail holding force According to Zou Mingxing, executive deputy general manager of Huazhou wood industry, the American MDI ecological adhesive without formaldehyde is used in the board, and the world's most advanced German diefenbach continuous press production line and continuous press plate making process are adopted, comprehensively realizing the new upgrade of homogeneous particleboard At the same time, the performance and environmental protection index of this kind of plate have also ended the history that the particle plate inevitably releases formaldehyde As we all know, the concentration of negative oxygen ions in the air is a sign of whether the air is fresh or not And SMIC negative ion health board is a kind of ecotype building material just on the market Its biggest characteristic is like a forest, which can release a large number of negative oxygen ions beneficial to human health At the same time, it can eliminate smoke and dust, kill bacteria and mildew, remove formaldehyde and purify air It is known as "indoor air purifier without plug-in and maintenance" According to the person in charge Chen Weixiong, the board contains expanded vermiculite which can release negative ions permanently After installation, the content of negative oxygen ions in the family space can be increased from the original 10-50 / cm3 to more than 1000-5000 / cm3 Environmental protection decoration should not be limited to material environmental protection is an eternal theme This is not only in the field of coating and plate, but also the necessary ceramic tiles for home decoration For example, this year's appearance of a microcrystalline is a new type of building material that can replace stone (stone decoration effect map) and ceramics It is made of granite chips and high-tech production Compared with ordinary stone and ceramic products, microcrystalline stone has more dense surface, color, purity, high hardness, non absorption and other advantages Its hardness and bending strength are twice that of marble, its acid resistance is four times that of ordinary stone, its alkali resistance is 20 times that of ordinary stone, and its radioactivity is four times that of international standard Due to the same texture, it can be bent and shaped, and can also meet the needs of hollow carving, color carving, repeated grinding and renovation It can be customized according to the shape and size In addition to being a conventional building material, it can also be made into screens (screen decoration renderings), murals, etc In addition, there is a kind of clean haze self-cleaning coating painted on the exterior of the building Its active substances can generate photocatalysis reaction through the excitation of sunlight, which can decompose oil pollutants and some inorganic substances; at the same time, it can eliminate static electricity, not absorb dust and other anti pollution and clean effects of the paint film It is undeniable that in recent two years, all kinds of new green building materials are richer, more selective and have various conceptual functions More and more people advocate environmental protection and decoration They have higher requirements for indoor air quality They should consider both beauty and health In the decoration, most people will try to use environmental protection decoration materials to minimize indoor pollution However, there are still many details to remind consumers First of all, to achieve real environmental protection, we need to pay more attention to not only decoration materials, but also design principles, design schemes, construction procedures, selection of decoration materials and indoor air quality inspection Peng Zheng, a senior designer in Guangzhou, believes that environmental protection decoration materials do not mean that the indoor environment must be up to standard In the design, consumers should consider the best use of decoration materials per unit area of the house, as well as formaldehyde of furniture, floor and other products
