Home improvement, environmentally friendly building materials need to be cautiously ventilated and most effective

Speaking of indoor air pollution such as formaldehyde that may be brought about by decoration, people are "talking about pollution." Professionals point out that artificial panels such as plywood, blockboard, medium density fiberboard and particleboard used for interior decoration do contain formaldehyde and can cause indoor air pollution. At the same time, all the use of environmentally friendly building materials is not 100% assured, because we must also consider the issue of "environmental capacity."

Many building materials now claim to be “green building materials”. In fact, their pollution is only below the limit set by the state. Therefore, the decoration company must be required to present the test report of the relevant materials in order to understand the actual environmental indicators. When the material is shipped to the construction site, carefully check that the material is in accordance with the contract. Even green materials can't be used at will, because the environmental performance of green building materials is only relatively improved, and it can't achieve true environmental protection. In addition, even the use of environmentally friendly building materials is not 100% reassuring, because there is also a problem of "environmental capacity". If the amount of environmentally friendly materials used is too large, it will make it difficult for the chemical preparations to evaporate quickly, resulting in pollution superimposed and causing decoration pollution. Therefore, to ensure that the air quality of the living room after renovation is environmentally friendly, the decoration should be simple and the decorative materials (even environmentally friendly materials) should be used in limited quantities. In addition, even if the decoration materials are as environmentally friendly as possible, the choice of furniture should also be considered, because harmful gases in some furniture will also cause environmental pollution.

In addition to trying to choose environmentally friendly building materials, simple decoration, and timely detection of formaldehyde pollution, it is necessary to understand some tips for dealing with indoor air pollution. Zhao Yesing suggested that people who live in new homes should first check the air in the living room before entering the house, and then choose the appropriate treatment method according to the situation that the harmful gas exceeds the standard. The most economical and effective way to eliminate indoor pollutants is to use ventilation. In addition, bamboo charcoal, activated carbon, negative ions, photocatalysts, etc., which are currently on the market, can also effectively treat indoor air pollution. Bamboo charcoal, activated carbon, etc. are all based on the principle of using carbon to absorb odor and adsorb harmful gases, to control indoor air pollution, low cost, no toxic side effects, but slow effect. This is used as a long-term treatment method for indoor air pollution slightly exceeding the standard. Negative ions can quickly oxidize harmful gases such as benzene and formaldehyde into negative ions, which are combined with air to be reduced to oxygen, water and carbon dioxide. This method can be used on a regular basis. The photocatalyst is newly introduced and applied from abroad, and it has a quick effect on heavy pollution, but its price is also high, and it may produce slight secondary pollution, which will affect the paint surface of wallpaper and wooden furniture. In addition, you can also consider the use of pure plant-based scavengers extracted from plants, or put some anti-pollution flowers and plants in the room can also play the role of "air purifier", such as ivy, spider plant, the leaves of Araceae, Prickly pear, aloe vera, tiger skin, etc., all have the function of absorbing formaldehyde and purifying air.
