In fact, it is not possible to judge the formaldehyde emission of furniture completely based on whether the indoor air quality meets the standard. The detection of formaldehyde emission and the detection of indoor air quality, the two detection schemes and standards are completely different.
Everyone can't help thinking that the materials I use and the furniture I buy are all environmentally friendly, and the indoor air quality test is also qualified. Why is the formaldehyde still exceeding the standard? In fact, the quality of finished furniture continues to rise, and the formaldehyde pollution of furniture is also declining. The source of formaldehyde pollution is not only furniture. There are also daily necessities such as curtains, fabrics, and plastic toys.
A good way to eliminate formaldehyde: ammonia
Many owners have their own methods to eliminate excessive formaldehyde. Don’t be too slow or too expensive. In fact, you only need to spend a few dollars to buy a bottle of ammonia, then close the doors and windows of the room, and put a basin of water in it. Inside, cover your nose and pour a small half bottle of bought ammonia into the basin, and then go out. After a week, the problem of excessive formaldehyde can be eliminated. It turns out that formaldehyde molecules can react with ammonia molecules. The fundamental reason is that the lone pair electrons of nitrogen atoms in ammonia attack the carbon atoms on formaldehyde, and an addition reaction occurs to form an unstable substance. After dehydration, the substance polymerizes into Sanya. Amino aldehyde, the substance is soluble in water, so as to achieve the purpose of removing formaldehyde. Everyone will try this method next time when decorating a new house.
