1, wall coating
Most formaldehyde comes from wall coatings. Adhesive contains a lot of formaldehyde and benzene, so toxic substances come from glue. So is the coating. Coatings are mainly composed of adhesives (also called film materials, adhesives, etc.). ), pigments, various additives and water (solvent). The toxic substances in the paint are mainly adhesives (adhesives). Therefore, the source of toxic substances in home decoration is glue.
Step 2: Floor
Wood floor is one of the main sources of formaldehyde. The main reason of formaldehyde emission comes from the wood floor itself and the glue used. Nowadays, many floors are made of artificial boards, which have a strong smell and pollution. In view of this situation, I generally recommend the use of tiles and the environmental protection level of glue. If you want a wooden floor, then the wood itself needs solid wood.
3. wallpaper.
We often use wallpaper now. When choosing wallpaper, we should pay attention to the wallpaper material, preferably paper wallpaper, and wallpaper glue is also one of the sources of formaldehyde, so we should also use environmental protection.
4. Wooden furniture
Wood furniture is the main source of household formaldehyde pollution, not one of them. When using wooden furniture, try to choose solid wood, and prove the environmental protection grade of E 1
5. Children's clothes.
Many mothers will buy clothes for their children, but many people are under great financial pressure, so they will buy some cheap clothes. In fact, whether the clothes of adults and children are formaldehyde or not, they should be cleaned when they are bought. Some are worse. The formaldehyde content will be higher, which will have an impact on children's health, especially in summer, which is the high incidence of formaldehyde outbreaks.
6. Gypsum board
Gypsum board is a commonly used material in home decoration. Because the home style is more unique and novel, gypsum board is usually the most commonly used. Although the formaldehyde content is less than other decorative materials, it does not mean that it is not, because a lot of curing glue is also used in the bonding process. Similarly, glue also contains a lot of formaldehyde!
7, latex paint
Speaking of latex paint, I believe everyone is familiar with it! Because today's young people always like to decorate their homes with various colors and change the monotonous home atmosphere, latex paint has become the first choice, but when choosing latex paint, we must pay attention to the following two points:
The harmful substances in waterborne latex paint are mainly volatile organic compounds and free formaldehyde. Now some big brands of latex paints and primers are water-based paints, and the environmental protection index of water-based latex paints is better than that of ordinary latex paints. The content of harmful substances in water diluted latex paint is greatly reduced.
Oily latex paint, on the other hand, is best not to smear oily products on the wall.
8. Glass glue
Glass glue will be used in the installation of kitchen and bathroom supplies and windows. Especially in order to improve the adhesion of furniture, glass glue will be used in the installation of bathtubs, washbasins and toilets. However, its active ingredients also contain a lot of formaldehyde. Oh!
9. For the treatment of formaldehyde, individuals advocate hierarchical management: different strategies are adopted according to the degree of pollution.
(1), formaldehyde pollution value is less than 1 times, and windows can be ventilated.
This is a simple, practical and economical method. No matter how much emphasis is placed on ventilation, as I suggested in "After Decoration, the Smell of Home". Beware of leukemia! You can also buy cheap fans to make your own fans, especially in some corners, such as the bathroom in the master bedroom and some hidden cabinets.
Remember, the ordinary breeze is not a drop, it must be guaranteed for 60 days.
(2) If the formaldehyde pollution value is less than 2 times, ventilate+place green plants+activated carbon (coconut charcoal).
Green plants such as Hupilan, Cymbidium hybridum and cactus all have the function of adsorbing formaldehyde. Planting some green plants at home can not only remove formaldehyde but also beautify the living environment. This is a two-in-one method.
Although plants can adsorb formaldehyde, their adsorption capacity is limited. It is unrealistic to remove formaldehyde by plants alone. It can only play an auxiliary role. New activated carbon and coconut shell carbon have all the characteristics of activated carbon and have the characteristics of activated carbon. Adsorption is longer and faster. Coconut charcoal is made of expensive coconut shells.
Secondly, you can buy some activated carbon as a means of supervision.
(three) to buy an air purifier that can eliminate chemical pollution within three times the formaldehyde pollution value.
At present, there are many kinds of air purifiers on the market that can remove pm2.5, but not many can remove decoration pollution. Less can effectively eliminate decorative pollution. You must read the product specifications carefully. But there is also a better way to judge: it is to test the actual effect of the air purifier, but it is easy to produce secondary pollution.
