Furniture that has been left for a year has no smell in winter, but it has a strong formaldehyde smell as soon as it arrives in summer.

Many people use the taste size to judge whether formaldehyde exceeds the standard. If you think so, it's all wet! The volatile gases in indoor building materials do have a great relationship with temperature, but it is very unscientific to measure the concentration of formaldehyde by nose.

One: less formaldehyde volatilizes in winter.

Due to the low temperature in winter, formaldehyde free molecules are not active in winter, but in summer, with the increase of temperature, indoor harmful gas molecules will become more and more active. The smell of indoor air in summer is often unpleasant. This is because the amount of formaldehyde volatilization increases. Formaldehyde is a colorless and odorless gas, which will produce a special pungent smell at high concentration. Because composite boards, high-density boards and large core boards will be used in the decoration process, these building materials will use a lot of formaldehyde in the production process.

Two: formaldehyde volatilizes more in summer.

The accumulation of harmful gas molecules in new houses in summer is particularly obvious. In summer, the indoor and outdoor temperatures are very high, so many families turn on the air conditioner in closed rooms, rarely open windows for ventilation, and indoor harmful gases. Molecules accumulate more and more indoors, making it difficult to disperse. The key point is that the volatilization period of formaldehyde is 3≤ 15 years. If the indoor pollution exceeds the standard, formaldehyde will not be treated in time, and the accumulation of indoor harmful molecules will cause chronic poisoning to the human body.

In fact, the formaldehyde concentration in summer is very high, and even the indoor formaldehyde concentration in summer is ten times normal. Summer is also the best season for formaldehyde control, and only comprehensive formaldehyde control can ensure the freshness of indoor air.
