Many homeowners in the renovation of new homes, in order to prevent indoor environmental pollution, go to the formal building materials market, to buy is in line with national standards of decoration materials - green paint, green floors, health furniture, please the formal decoration company, spent Is the price of high-end decoration, but after the completion of the renovation, formaldehyde exceeded 6-7 times, benzene exceeded 3 times more than ... .... Where is the problem? Is green material credible and credible? Is decoration pollution really impossible to prevent? Let Xiao Bian tell you where the decoration pollution comes from, and what needs to be done to clean the indoor air. Many building materials are now nominally "green building materials" and "environmental friendly materials" without any pollution. In fact, "green building materials" and "environmental protection materials" do not mean that there is no pollution, but that their pollution is lower than the standards set by the state. For example, if the formaldehyde emission of some plates is less than 0.15 mg per cubic meter, it can be called “green building materialsâ€. In other words, under the current level of production and conditions, green building materials are not completely free of harmful substances, and they only control harmful substances within the minimum standard values. Decoration pollution is not a matter of material alone, and prevention of decoration pollution requires attention to two aspects. The first link: Indoor environment awareness when doing the overall design of decoration Why do some of the consumers choose to decorate all the environmental protection materials, but after the renovation of indoor air pollution? There is a question of choosing a fitting design solution. The design mentioned here refers to the design of materials and layout of the whole room for the consumers, such as what materials are on the ground, whether the walls are painted or wallpapered, the volume of the furniture, and the selection of materials. In determining the home decoration design program, we must pay special attention to the following three aspects: The first is a reasonable calculation of housing space carrying capacity. Since various decorative materials currently on the market will release some harmful gases, even materials that meet the national standards for hazardous materials for interior decoration materials will cause harmful substances to exceed the standard in a certain amount of indoor space. Followed by using a variety of decorative materials. Especially for ground materials, it is better not to use a single material because ground materials account for a large proportion of indoor decoration and are prone to indoor air pollution. The last step is to keep a good amount of pollution for buying furniture and other decorative items. Because a variety of pollutants can be superimposed, if interior decoration hazardous materials have already exceeded the national standards, if you purchase furniture and other decorative items, it will certainly cause excessive indoor pollution. The second link: pay attention to the construction process The China Indoor Environmental Testing Center has found through inspections in recent years that the indoor environment pollution caused by the unreasonable construction process is showing an increasing trend, mainly in the following two aspects: First, the issue of floor paving. Pavement lining under solid wood flooring and composite flooring is a traditional process, but this has caused a lot of environmental pollution. This is because large core boards and other wood-based panels under the floor all contain formaldehyde and cannot be closed. And ventilation, and the use of a larger area, in addition to some construction workers use inferior materials, exacerbated the content of harmful substances, resulting in indoor formaldehyde pollution is not easy to remove. Followed by the wall finishing problems. When carrying out the wall finishing project according to the regulations, basic treatment shall be carried out and the interface agent shall be applied to prevent the wall surface from peeling or cracking. Some construction workers only use paint varnish for the primary treatment, and most of them use low-grade varnish. A large amount of thinner is added during brushing, causing serious benzene contamination. Because it is enclosed in putty and wall paint, It will volatilize indoors for a long time and it will not be easy to remove. Environmental detection building materials purchase
