In order to ensure the quality of newly renovated houses and prevent indoor environmental pollution, many consumers buy decorative materials that meet the national standards in the formal building materials market. Please ask for a formal decoration company. The price is for high-end decoration, but the price is high. After the renovation, it was discovered that a contaminated house was installed. Where is the problem? Is the green material credible and unreliable? Is the decoration pollution really impossible to prevent?
â—†Preventing decoration pollution should pay attention to two links
According to the director of China Indoor Environmental Monitoring Committee Song Guangsheng, decoration pollution is not a separate material problem, and prevention of decoration pollution should pay attention to two links.
The first link is to have an indoor environmental awareness when designing the overall design. Why do some consumers choose environmentally friendly materials for decoration, but there is still pollution in the indoor air after renovation? There is a problem of reasonable choice of decoration design. The design mentioned here refers to the design of the overall structural materials and layout of the room, such as what materials are laid on the floor, whether the wall is painted or wallpaper, the volume of the furniture and the materials selected.
When determining the design plan for home decoration, pay special attention to the following three aspects: First, calculate the space carrying capacity of the house reasonably. As various decorative materials 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. The second is to use a variety of decoration materials. Especially for the floor material, it is best not to use a single material, because the floor material accounts for a large proportion of interior decoration, which is likely to cause indoor air pollution. Finally, the amount of advancement for the pollution of furniture and other decorative items is kept. Because various pollutants can be superimposed, if the indoor hazardous materials have been critical to the national standard at the end of the renovation project, if the furniture and other decorative items are purchased, the indoor pollution will definitely exceed the standard.
The second step is to pay attention to the construction process in the decoration. Through the testing in recent years, China Indoor Environmental Testing Center found that indoor environmental pollution caused by unreasonable construction technology is showing a growing trend, mainly concentrated in the following two aspects: First, the problem of floor covering. The laying of linings under solid wood flooring and laminate flooring is a traditional process, but this has caused a lot of environmental pollution, because the large core boards and other wood-based panels laid under the floor contain formaldehyde and cannot be closed. And ventilation treatment, and the use of a relatively large area, in addition, some construction workers use inferior materials, more harmful content of harmful substances, resulting in indoor formaldehyde pollution that is difficult to remove. Followed by the problem of wall finishing. When performing wall finishing work according to the regulations, it is necessary to carry out the base layer treatment and apply the interface agent to prevent peeling or cracking of the wall surface. Some construction workers only use varnish for base treatment, and most of them use low-grade varnish. When adding a large amount of thinner, it causes serious benzene pollution. Because it is enclosed in putty and wall paint, it is enclosed in putty and wall paint. It will evaporate indoors for a long time and is not easy to remove.

Nowadays, many building materials are nominally “green building materials†and “environmental materials†without any pollution. In fact, "green building materials" and "environmental 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€. That is to say, under the current production level and conditions, green building materials are not completely free of harmful substances, but only control harmful substances within the minimum standard value.
Therefore, even if you buy environmentally friendly materials, even if it is low pollution, you should pay attention to the release of contaminated gas and then stay.
