What is the harm of formaldehyde? The harm of formaldehyde is also popular here. In fact, many things in life contain formaldehyde, but a small amount of formaldehyde is not a big problem. However, if formaldehyde exceeds the standard, it will easily lead to the decline of human immunity, which may lead to leukemia and cancer. Long-term exposure to excessive formaldehyde will affect their health. Therefore, for the health of family members, we must pay attention to formaldehyde when decorating.
How to avoid formaldehyde exceeding the standard 1 in decoration, and how to use environmental protection materials in decoration building materials?
To avoid excessive formaldehyde in decoration, we should start from the source of decoration materials, such as putty powder for painting walls at home, try to choose finished putty powder, and don't use 108 double ash putty powder on site. Coatings should also choose well-known brands that meet environmental certification standards, such as ten ring certification of domestic coatings and Der Blaue Engel certification of some foreign coatings. When you buy paint, you should also see it clearly. Inferior paint can easily lead to benzene series (benzene
2. Customize the furniture and choose the plates that meet the standards.
Now many people customize furniture at home. When customizing furniture, you can choose solid wood panels directly if you have a budget. If the budget is not very important, you should choose panel furniture. You should pay attention to the environmental protection of the panel, which also depends on whether the panel meets the national standard E 1 or the foreign F4 star standard.
In addition, it is not appropriate to customize too much custom furniture at home. Don't fill the whole house with cabinets, because sometimes the formaldehyde content of a cabinet does not exceed the standard, but if there are too many cabinets, the formaldehyde content will be superimposed, which may also cause formaldehyde to exceed the standard. Customized furniture should be enough.
Don't covet cheap curtains.
Curtains, bedding and fabric sofas are actually formaldehyde. Don't be greedy when buying. Choose some merchants without quality assurance. After buying the curtains, it is recommended to clean them before hanging them.
Teach you six in addition to formaldehyde methods. After the house is renovated, whether the formaldehyde in the house exceeds the standard cannot be judged by the taste. You should find a CMA-certified testing organization to test formaldehyde. As far as I know, the fees charged by this testing institution are generally calculated by space. For example, a room is a space. For example, a room in 500 yuan, such as a house with three bedrooms and two halls, costs about 2,000 yuan, and there will be a detailed inspection report.
If your home detects that the formaldehyde content in the indoor air exceeds the standard, you can use these six methods to control the air and reduce the formaldehyde content in the indoor air.
In addition to formaldehyde Method 1: Open the window for ventilation.
After the house is renovated, it will take 3-6 months to ventilate before moving in. After moving in, you should always open the window for ventilation to speed up air circulation and formaldehyde volatilization. Ventilation is the simplest and most effective method in in addition to formaldehyde.
In addition to formaldehyde Method 2: Photocatalyst Air Treatment
Photocatalyst air treatment is also very common now. Many people have just finished decorating their homes or companies, and they will ask the air treatment company to carry out photocatalyst treatment. Photocatalyst is both a photocatalyst and a catalyst. Under the action of light, harmful organic substances such as formaldehyde, toluene and TVOC can be decomposed into harmless gases, thus achieving the purpose of in addition to formaldehyde. However, this photocatalyst treatment can only treat the symptoms, not the root cause, and can only remove the formaldehyde on the surface of the article in a short time and slow down the release of formaldehyde. Personally, I think the effect is average, but I do some light treatment.
In addition to formaldehyde Method 3: Biological enzyme air treatment.
Biological enzyme is a catalytic organic substance produced by living cells. Protein, which is usually extracted from plants, is atomized by a certain technology and sprayed into the indoor air, so that it can fully contact with harmful molecules in the air and destroy the atomic structure of harmful gases, so biological enzymes can remove formaldehyde from the air. But we all know that the cycle of formaldehyde release from indoor decoration pollution sources is generally 5- 15 years. The principle of biological enzyme in addition to formaldehyde is to remove pollutants in the air, which means that it must be sprayed in the air for a long time to have a certain effect.
In addition to formaldehyde method 4: fresh air system
When decorating your home, you can install a fresh air system. The fresh air system itself does not have the function of in addition to formaldehyde, but it can exchange indoor air and outdoor air, and dilute harmful gases such as indoor formaldehyde by exchanging fresh air. Therefore, the fresh air system has a certain effect on in addition to formaldehyde and can improve the indoor air environment. Therefore, if you have a budget, you can consider installing a fresh air system for home decoration.
In addition to formaldehyde Method 5: Air Purifier
Air purifiers are now available in many people's homes, and air purifiers can also play a certain role. The filter screen of the air purifier can decompose formaldehyde into carbon dioxide and water to avoid secondary pollution. The key to choosing an air purifier depends on the clean air output rate (CADR value), and a little higher is relatively better. For example, the clean air output rate CADR of Blueai 380iF is 400m3/h, which is higher than many domestic purifiers.
In addition to formaldehyde Method 6: Place green plants.
Many people know that putting a few pots of green plants at home after decoration can help absorb formaldehyde, but the role of green plants is very small, but there is no harm in putting a few pots of green plants, so you can still put a few pots of green plants after decoration.
The above six methods can be learned in in addition to formaldehyde, but the effect of post-processing is still very limited. It is suggested to reduce formaldehyde pollution from the source when decorating, such as laying wooden floors at home and choosing formaldehyde-free floors. In 2020, Youshi Flooring introduced formaldehyde-free additive products, mainly three-layer solid wood composite flooring and new five-layer solid wood composite flooring. The formaldehyde emission was ≤0.020mg/m3, and the limited label was ENF+. You's formaldehyde-free floor is made of logs, bio-based raw materials and medical-grade MDI formaldehyde-free glue, and the surface is coated with high-performance environmental protection paint, which is relatively environmentally friendly.
