Formaldehyde removal method

If you are not in a hurry to move into a renovated new house, it is mainly ventilated, preferably for half a year, and the most important thing is summer!

Because "half a year" is the boundary, it just avoids the time when organic pollutants (benzene series/ammonia /TVOC) other than "formaldehyde" will "volatilize". In addition, a more important parameter is added: "Summer"/"Long-term ventilation".

Knowledge points should be known: the volatilization period of formaldehyde is 3- 15 years, and the time of volatile organic compounds such as benzene, benzene series /TVOC is 3-6 months.

The volatilization amount of formaldehyde is between 3- 15 years, which is always in dynamic change, that is, the volatilization amount in the first month and the second month will change differently, and the specific change range depends not only on the materials used and the edge sealing process, but also on the external environment (such as temperature/humidity/ventilation, etc.). In essence, the formaldehyde emission rate of dry-molded furniture has been decreasing under the same environment. From a straightforward point of view, the number of cardboard at home is constant, that is, the content of pollutants is certain. With the continuous discharge, the total amount of residual pollutants in cardboard will be less and less, and the decomposition of urea-formaldehyde resin in cardboard will be slower and slower, and the speed of producing free formaldehyde will be slower and slower, which is not enough to cause human discomfort. So this paragraph shows that the longer the opening hours, the better.

What's the difference between opening and opening for one year? I want to analyze it again.

For serious pollution, within one year, it may become moderate pollution, and half a year may be between moderate and serious, but obviously, long-term exposure to this environment is harmful to human body.

Moderate pollution, changed to light pollution or standard within one year, changed to moderate or light pollution within half a year, and changed to no pollution for half a year under special circumstances.

If it is light pollution, both of them must be ventilated for a long time in summer (no sultry phenomenon) before they can finally reach the standard.

To sum up, there is a big difference between severe and moderate time difference, and the difference between mild pollution is small.

However, the sensitivity of human body to formaldehyde is different, and some people are at 0. 1mg/m? When, can't feel the stimulation of formaldehyde; And some susceptible people may be at 0.05mg/m? You can clearly feel it when you are young. Whether you meet the standard or not lies not in the standards and regulations, but in whether your body adapts to this environment.

The national standard GB 18883-2002 stipulates that the formaldehyde concentration is 0. 1mg/mL.

In the end, the concentration of free formaldehyde in indoor air will be affected by many factors. It is recommended to find a professional institution for testing before check-in, and check in after passing the test!
