After the house is decorated, some harmful gases may remain in the room, such as formaldehyde, toluene, TVOC and other harmful substances. If we move in immediately, it will have a great impact on the body. , Therefore, we need to wait until these harmful substances are released and meet the standards before moving in. How long does it take for formaldehyde to be released after decoration?
We must know that the natural release of formaldehyde will definitely not be released completely. We can only say that formaldehyde will be reduced.
However, there is no specific answer to how long formaldehyde will last, because the release cycle of formaldehyde is 3-15 years. The volatilization of formaldehyde gas during decoration is very slow, and the activity cycle is 1-10 years, or even longer. After 5 years, the volatilization slows down and people tend to ignore it more easily.
However, free formaldehyde can generally evaporate after about 2-3 months of ventilation.
Formaldehyde has a great impact on our bodies, and it is easy to make mistakes. For example, the following misunderstandings:
Misunderstanding 1: Only new houses contain formaldehyde?
It has been almost 4 years since the renovation. How can there be any formaldehyde?
Formaldehyde comes from the adhesives of various types of boards that are common in our lives. They originally existed inside the boards in the form of phenolic resin , urea-formaldehyde resin or melamine formaldehyde resin , because these three resins require Formaldehyde can be synthesized, so it is also collectively called trialdehyde glue, so there is a saying that "no glue can be formed without formaldehyde".
This glue will continue to decompose and slowly release formaldehyde during use. This process can last for more than 15 years. There are also things to note. Although some houses are old, the furniture is newly purchased. If the new furniture uses boards with a large amount of formaldehyde release, the indoor formaldehyde will exceed the standard.
Myth 2: If there is no odor in the room, there is no need to control formaldehyde?
Formaldehyde is a colorless and odorless gas. The pungent smell we smell indoors may be the smell of benzene solvents such as toluene. They are solvents commonly used in decoration materials such as paints and adhesives, and have strong Irritating. There are also some pungent odors coming from TVOC, which can also pose a threat to health. Formaldehyde is not as high-profile as toluene and TVOC. It doesn't talk much, has no color, and its smell is relatively light at low concentrations. Only at high concentrations can you smell a rancid smell. So even if we don't smell any odor indoors, the concentration of formaldehyde may still exceed the standard.
When we are preparing to move into a new house, the first correct thing to do is to ask a professional formaldehyde testing agency to conduct formaldehyde testing. If the testing exceeds the standard, targeted treatment will be carried out. In this way, only if all tests meet the standards before moving in can the health of the family be ensured.
