Is formaldehyde colorless and odorless?

In fact, everyone is aware of formaldehyde, but they do not know what kind of substance it is. In fact, formaldehyde is colorless and odorless, and people have no way of perceiving its existence with the naked eye. However, if the formaldehyde content in the air exceeds the standard, it will have a great impact on people's respiratory tract and other organs, and may even cause formaldehyde poisoning, which will endanger life.

Autumn and winter are about to begin, and most people will choose to decorate their houses during this season and move in before the Chinese New Year. In fact, this approach is wrong. The indoor temperature is high and the air is dry, making this environment a hotbed for toxic and harmful substances. The boiling point of formaldehyde is 19°C. Data show that the temperature rises by 1°C. It is now the winter heating period, and the indoor ventilation is poor. A large amount of formaldehyde hidden in paints, floors, and furniture is released, and its toxicity is more than 10 times higher than normal.

Some people think that if the smell is not strong, there is no formaldehyde. In fact, formaldehyde is colorless and odorless. The volatilization of formaldehyde is affected by temperature. The smell is light when the temperature is low, and it will become heavier once the temperature rises. Secondly, there are still a lot of benzene substances after decoration, so no odor does not mean safety.

Opening windows for ventilation is the most direct and effective way to reduce the accumulation of harmful gases in the room after decoration. Indoor air circulation can reduce the content of some free harmful substances in the indoor air, avoid the accumulation of harmful substances indoors, and reduce the harm of harmful substances to the human body. Many people think that a new house can be moved in after being ventilated for three months because the smell will no longer be noticeable. However, studies have found that the release of formaldehyde is a slow and long process, and indoor air circulation still needs to be maintained for a long time after moving into a new house.

If the outdoor air quality is poor, opening windows for ventilation will make the indoor air quality of the new house even worse. In addition, when opening windows for ventilation in a new house, you should pay attention to weather changes to prevent rain from falling into the room through the windows, especially the wooden wardrobes, wooden floors, etc. next to the windows. If they are accidentally soaked by rain or get damp, it will affect the decoration effect.

Homes decorated with environmentally friendly materials still have excessive formaldehyde levels because in a limited space, the pollution released by decoration materials, furniture, etc. has a cumulative effect, which will also cause formaldehyde levels to exceed the standard. Just like when one person smokes in a closed space, the smell may be relatively small, but when many people smoke together, the smell will be very strong.
