It is understood that at present, the building materials market can see children's formula paint, biological gene coating, net odor paint, zero-VOC organic volatile matter coating, and many paint products are “zero pollutionâ€, even paint has “health functionâ€. Exaggerating the promotion of its environmental safety performance has misled consumers. When consumers enjoy the joy of moving, they often easily overlook the most basic problem of home health, that is, for decoration materials, especially whether the selected paint and paint contains toxic components.
Worrying detection
It is understood that room pollution comes from many aspects, there are problems with furniture itself, there are problems with the decoration process. Some consumers choose environmentally friendly products, but what they buy may not be truly environmentally friendly. The reason why this is so is because current industry management is not standardized and the standards are not uniform.
Some of the standards are industry standards, some are standards of local quality supervision; others have sample inspections, and some industries implement inspections. This causes consumers to see a “qualified test report†when they purchase products, but in reality it may not. Qualified, it is difficult to judge whether the product is qualified by inspection report alone. Taking China's single test for furniture as an example, the following questions are kept: First, formaldehyde detection is only for artificial plates, not the finished furniture used by consumers. The second is that only the content of heavy metals in the paint has been stipulated, and no other pollution has been asked. The third is to ignore the pollution caused by the release of harmful substances in the paint. The fourth is to ignore the pollution caused by the release of harmful substances in the adhesive. In fact, there are more and larger sources of pollution in these neglected projects.
The above is only for the detection of furniture loopholes, in fact, in the decoration process, especially the floor, stone, floor tiles, paint and other decoration materials will also cause pollution.
The culprit turned out to be an adhesive
Many people know that the decoration pollution is caused by formaldehyde, benzene series, etc., but which part of the decoration comes from? It is understood that the construction of artificial board and woodworking is an important aspect of pollution sources.
First of all, artificial plate links. Natural wood chips, hibiscus, wood shavings, etc. are themselves non-toxic. Why is it poisonous after being made into plates? Because the glue used for making plates has formaldehyde or cyanide, the boards it produces are toxic. At present, many teak, maple, eucalyptus, etc. in the market are made of 1mm-thick logs of teak, maple, and eucalyptus wood glued on the surface of artificial boards, and then brushed with wooden paint, rather than real In the solid wood. There are also some powerful brands and companies on the market. Solid wood panels are used, and prices are generally relatively high. Therefore, the level of E0, E1, E2 and even no grade in the panel, furniture, and wood floor is closely linked to the environmental protection of the glue used in the selection of the board.
Secondly, plywood, big core boards, etc. should be made into furniture, and a layer of panels must be glued. If the glue of your plywood is toxic, then your finished furniture will also be poisonous. In addition, the wood lacquer link is also very important, and now waterborne wood ware is more and more widely used, its environmental protection is enough to ensure the safety of the human body. The reason is also due to the improvement of environmental protection such as adhesive emulsions such as acrylic acid.
Call for the development of standards for the use of decoration materials
Home decoration, the use of putty putty on the treatment of the wall, and putty putty if you want a solid quality, you need to add a lot of glue. Currently putty putty mostly use 107,108 glue on-site modulation putty. It is understood that one square meter of wall-covered ash should be secured with about 0.5 kilograms of glue. If it is a wall of 200 square meters, 100 kilograms of glue should be used.
And if the 100 kilograms of glue in accordance with the national standard to be calculated to contain 100 grams of formaldehyde content of formaldehyde glue GB18583-2001 standard: formaldehyde ≤ 1 g / kg of plastic. This 100 grams of formaldehyde is evenly volatile in a 250-cubic-meter home according to national standards. It takes 4000 days to complete. Visible, the formaldehyde produced by the putty putty can not be overlooked.
Industry experts pointed out that there are odors in the decoration, resulting in formaldehyde, benzene series, cyanide, halogenated hydrocarbons and other toxic hazards, the root cause is caused by a large amount of glue used in wood-based panels, woodworking, putty putty, wallpaper and other links. Especially formaldehyde. A large amount of formaldehyde must be evaporated for several years or even more than ten years to complete.
To this end, we call on relevant departments to formulate a unified standard for the use of interior decoration materials, rather than each individual industry; to improve the entry threshold for production units in the decoration and decoration industry, especially those necessary for home improvement such as paints, coatings, and plates. The production threshold for products such as adhesives, tiles, etc.; the sampling inspection system for decorative materials, not the current inspection system, and the implementation of sampling inspection system can reduce the entry of toxic raw materials into the circulation market and prevent the occurrence of some falsified products.
