According to effective statistics, there are 90 million houses in China for decoration, of which more than 60% have varying degrees of formaldehyde pollution, which exceeds the national standard by more than 10 times. Of course, this is only the proportion of official statistics, and we can know from the recent news that many reports of formaldehyde exceeding the standard should actually be more serious.
Many people in life have a certain awareness of formaldehyde, but because formaldehyde release sources are ubiquitous in life, coupled with the fact that many people have little understanding of the scientific detection and treatment of formaldehyde, this also leads to the tragedy caused by formaldehyde is still endless.
Here, I would like to remind you that if you want to effectively prevent the problem of excessive formaldehyde, the first thing to do is to have a comprehensive understanding of the formaldehyde release source, and today we will reveal three types of common things in life, which are the main sources of indoor formaldehyde exceedance, and the formaldehyde content is particularly amazing.
1. Particle board and MDF products.
This kind of wood products are particularly common in life, and every family has them, such as wardrobes, closets, beds, tatami mats, coffee tables, TV cabinets, etc., most of which are made of this kind of board.
Particle board, MDF contains a lot of formaldehyde, this is because they will use a large number of industrial glue in the production process, and formaldehyde is an important part of this kind of glue, is the so-called "no formaldehyde is not glue", some decoration masters said, like this kind of board only a few pieces can make the room formaldehyde concentration value exceeded, not to mention the use of a large number of boards made of wardrobes, closets and other large pieces of furniture.
2. Mattress. Mattress is a special source of formaldehyde release, and the reason why it contains formaldehyde is also because it contains a large amount of adhesive inside.
And mattresses don't need to contain too much formaldehyde to have a huge impact on our health, because we have at least 8 hours of zero contact with it every day. Here is also a special reminder to everyone, buy mattresses must choose qualified products, do not be greedy for small bargains.
3. Decoration wallpaper and latex paint.
Most friends know that whether they use wallpaper or latex paint when decorating, they contain a lot of formaldehyde, and the area they involve is particularly large, so it is particularly easy to lead to excessive formaldehyde.
Here to popularize science, the wallpaper itself does not contain much formaldehyde, but a lot of glue will be used when pasted to the wall, so that the formaldehyde produced by wallpaper decoration is not inferior to latex paint, or even better.
As for the big difference between drying for half a year and drying for a year? We need to dissect it again.
For heavy pollution, one year may turn into moderate pollution, and half a year may be between moderate and severe.
It can be deduced that the indoor formaldehyde content does decrease over time, and the lower the initial indoor formaldehyde concentration, the easier it is to meet the standard.
But the sensitivity of the human body to gases is different, and some people are at 0At 1mg m, the stimulation of formaldehyde is not felt; However, some susceptible people may also feel slight discomfort when the formaldehyde concentration is very low.
For a family, it is not only to see whether the value meets the standard, but also to see whether the body can adapt.
Every family's situation is different, maybe someone else's family can move in half a year, you may have to take two years.
Therefore, before moving, be sure to check whether the specific formaldehyde exceeds the standard.
