At what temperature will formaldehyde volatilize?

Formaldehyde is a chronic volatile substance, and its volatilization period is as long as 3- 15 years. 19-29 degrees Celsius, and began to evaporate into the air. The formaldehyde emission is directly proportional to the temperature, and the higher the temperature, the greater the formaldehyde emission. The space inside the car is limited, and the concentration can easily soar at high temperature, which is why it is particularly easy to smell the odor inside the car in summer.

In automobiles, formaldehyde is widely found in various colloidal materials, such as hard plastics, floor adhesives and leather chairs in automobiles, all of which contain formaldehyde. Carpet, interior decoration, ceiling, seat assembly, automotive wiring harness and other parts may release harmful gases. "Summer is the best time to remove the odor inside the car, and it is also the most serious time for vehicle air pollution. So be sure to set aside time to open the window for ventilation before driving. "

Extended data:

Health hazards of formaldehyde;

1. irritation: the main harm of formaldehyde is the irritation to skin and mucosa. Formaldehyde is a toxic substance in protoplasm, which can combine with protein. When inhaled in high concentration, severe respiratory irritation and edema, eye irritation and headache may occur.

2, sensitization: direct skin contact with formaldehyde can cause allergic dermatitis, pigmentation, necrosis, inhalation of high concentration of formaldehyde can induce bronchial asthma.

3. Mutagenesis: High concentration of formaldehyde is still a genotoxic substance. Experimental animals can cause nasopharyngeal tumors under the condition of high concentration inhalation in laboratory.
