[] now, people pay more and more attention to healthy life, and environmental protection home decoration has been mentioned many times. Everyone knows that home decoration is toxic, but we know little about where it comes from. As a series of problems of decoration pollution are discovered and recognized by people, environmental protection and health have become a hot spot in decoration. More and more owners begin to pay attention to this problem, and have strict requirements for the environmental protection and health of their houses. Usually, we pay more attention to wall paint and plates, so that the content of toxic substances detected after all decoration with green environmental protection materials still seriously exceeds the standard, smells bad, and even leads to the decline of human immunity and disease. Why is this? In fact, home decoration is a complicated process, and even unremarkable glue is closely related to environmental protection

myth 1: there are toxic gases such as formaldehyde and benzene in home decoration, so it's OK to open more doors and windows for ventilation after decoration.

fact: whoever is willing to move into the newly decorated house starts to stay away from health, and home decoration should not be toxic. It's because of the use of chemical glue that it is toxic, and the formaldehyde release time in glue is up to 3— For 15 years, it's useless to open a few months' window. Many houses have lived for many years. They close their doors in the morning and go to work at night. When they open the door after work, they still smell the pungent smell. This is because a large amount of formaldehyde in the glue is slowly released

Myth 2: please deal with home decoration pollution. Just deal with the company.

fact: treatment is only to temporarily reduce a little toxic substances. It can only remove the toxic substances that have volatilized, not the toxic substances in the plates, walls, etc., which will be in 3— It is slowly released within 15 years and endangers the health of hot bodies. Moreover, the governance methods used by the company, such as photocatalyst, aldehyde remover, activated carbon and so on. Some will also bring secondary pollution, and they are also disinfectants themselves, which will not work on the newly released formaldehyde after consumption

myth 3: toxic boards and furniture cannot be solved, and the dust on the wall is a small matter, which is not worth mentioning

fact: the wall is one of the most important links in home decoration, which not only covers a large area, but also covers the whole room. Shuangfei powder is originally non-toxic, but it needs to add a lot of chemical glue when making putty, which leads to toxicity. And everyone mistakenly believes that putting on putty is a trivial matter, which leads to the use of inferior glue, which makes the air in the city worse

myth 4: the toxicity of home decoration mainly comes from plates and coatings, not glue

fact: glue is the root cause of the toxicity of plates and coatings. Wood, the main component of the board, is a natural plant, which is non-toxic. However, adhesives (i.e. glue) should be used in the process of manufacturing the board, and the adhesives contain a large amount of formaldehyde and benzene, so the toxic substances come from glue. Paint is also the same. Paint is mainly composed of base materials (also known as film materials, adhesives, etc.), pigments, various additives and water (solvents), and the toxic substances inside are mainly base materials (adhesives). Therefore, the fundamental source of toxic substances in home decoration is glue

myth 5: it should be no problem to choose environmental protection products for home decoration materials and find a regular company for decoration

fact: at present, green environmental protection building materials on the market can only be regarded as up to standard, in fact up to standard ≠ Environmental protection, more ≠ non-toxic. For example, for a room with a building area of 100 square meters, 100 kg of glue (excluding glue for furniture panels) is required for wall putty alone. If it is calculated according to the national standard, the 100 kg glue contains 100 grams of formaldehyde (the national standard gb19583-2001 stipulates that only when the formaldehyde content is less than or equal to 1 gram/kg glue can it meet the standard). This 100 grams of formaldehyde in a 250 cubic meter room according to the national standard, it takes 5000 days to volatilize

remarks: the scope of indoor environmental pollution control of civil building engineering (2006 Edition) gb50325— The class I standard of formaldehyde content in 2001 is: formaldehyde is less than or equal to 0.08 mg/m3 air · Days. In 250 cubic meters of air, formaldehyde less than or equal to 20 mg/day can reach the national standard (0.08 mg/cubic meters x250 cubic meters =20 mg), that is, on the premise of reaching the national standard, it takes 5000 days to release (100 grams of formaldehyde%20 mg/day =5000 days)

to sum up, there are odors, formaldehyde, benzene, cyanide, halogenated hydrocarbons and other toxic substances in home decoration. The root cause is from all the places where glue is used in home decoration such as furniture, putty and wallpaper. In most cases, we use chemical glue, which cannot be technically free of formaldehyde and benzene, so this pollution cannot be solved. However, now there has been a kind of plant glue and adhesive (wood glue, putty glue, wallpaper glue, etc.) that completely does not contain toxic substances such as formaldehyde and benzene. It is extracted from natural plants and completely does not contain toxic carcinogens such as formaldehyde, benzene, xylene, etc., realizing real green home decoration. You can stay after decoration
