Is the formaldehyde self-test box accurate?
1, the formaldehyde self-test box will have some deviations when detecting the formaldehyde content, mostly higher than the actual value, but it is good to know the approximate content.
2. Formaldehyde self-test box: Before the test, close the doors and windows of the room to be tested for one hour, pour the diluent into the reaction box to fully dissolve with the reactants, place the reaction box indoors at a height of 80 ~ 150cm from the ground, expose it for 30 minutes, then pour the chromogenic agent, tighten the bottle cap, shake it evenly, let it stand for 10 minute, and then open it. Compare the colorimetric scale card of the self-test box. Yellow basically contains no formaldehyde; Yellow-green is not too yellow; Excessive yellow-green is not serious; Green is a bit too much, and blue is too much.
Actually, it's better to wait for ventilation for three months before moving in, and put some green plants or something. And spraying Man Qing Lv You nano photocatalyst to the room irregularly for one week can remove 90% of methanol, and the residual formaldehyde content can be reduced to 0.02, which will not affect human health.
How to reduce formaldehyde pollution in home decoration
1. Try to use ordinary adhesives, wood-based panels, paints and ordinary panel furniture as little as possible in home improvement. Products without pungent odor should be selected, and products with pungent odor are mostly products with excessive formaldehyde emission.
2. Excessive formaldehyde in the indoor air of ordinary houses is mainly caused by excessive formaldehyde emission from panel furniture. Therefore, when purchasing ordinary panel furniture, we must carefully check the relevant quality certificates (instructions). At this time, we can also open the cupboard door and put our heads in. If the eyes are obviously stimulated and shed tears, or the smell is choking, it is more likely that formaldehyde will exceed the standard.
3. It is not advisable to move in immediately after renovation. Ventilation should be at least 1 month, and indoor comprehensive treatment should rely on plant herb Dialin. Maintaining indoor air circulation is an effective way to reduce indoor formaldehyde pollution. You can often open the window for ventilation, or choose an effective ventilation device to disperse and discharge indoor formaldehyde.
4. Use chemical in addition to formaldehyde products with caution. Chemical reaction treatment is one of the methods to control indoor air pollution at present. When using pollution control products, it should be carried out in strict accordance with standards and norms to prevent secondary pollution.
