Formaldehyde has two characteristics:
One: the volatilization point is 19℃, and the higher the temperature, the more intense the volatilization;
Second, the incubation period is as long as 3- 15 years.
These two characteristics make formaldehyde a "stubborn element" of air pollution.
The volatilization point of formaldehyde is 19℃, and the concentration increases by 0.4 times with each degree of temperature increase, especially in spring and summer. When the temperature increases, the release is more intense, and the concentration will be three times higher than normal. In winter, indoor air quality is qualified, but in summer, in addition to formaldehyde exceeds the standard. This is because formaldehyde is dormant in winter, and its volatilization will be intensified when the temperature reaches 19℃ and higher in spring and summer. According to the survey, 90% of newly renovated families have exceeded the standard of formaldehyde.
Friends who live in the north are hot in winter, and the boiling point of formaldehyde is 19 degrees. Turn on the heating, the indoor formaldehyde content will increase by more than 5-6 times, and it is generally not ventilated in winter! It is very harmful to children and the elderly with low immunity! Especially the newly renovated house.
Indoor air pollution is very harmful. For the sake of family health and reducing pollution hazards, we should pay attention to: buy and use green materials during decoration, and control the hazards from the source. Secondly, the renovated house can't be moved in immediately, and it needs ventilation for a while. Find a special indoor air quality testing agency to conduct air quality testing, and then check in. If it is unqualified, it needs to be treated until the air quality reaches the standard! According to statistics, 90% of children with leukemia have a history of decoration within half a year, and it usually takes three years for houses to be decorated and polluted-ignorant love is the biggest harm! Care for breathing! Cherish health!
