A newly renovated house will give you a headache if you live for a long time. How to deal with it?

Newly renovated houses will have a headache for a long time because of some materials we use, such as wall painting materials, wood floors, wood glue, wood paint and so on. , it will contain some harmful substances such as formaldehyde.

The treatment method is as follows:

Open the window to ventilate.

Just after the renovation, the smell of the new house is serious, and the pollution will definitely exceed the standard several times or even dozens of times. Therefore, the best way to remove formaldehyde in the early one to two weeks is to open the window and ventilate for a long time, and discharge the pollutants in the indoor air outdoors through air convection.

In addition, electric fans can also be used to accelerate indoor and outdoor air flow. This method can quickly reduce the content of harmful substances in indoor air.

Use activated carbon.

After effective ventilation, indoor air pollution has been greatly reduced, so now the focus of governance should be shifted to solving the source of slow release of indoor pollution to ensure the long-term stability of the healthy environment at home.

Because the release period of indoor decoration pollution is 3- 15 years, this slow release process determines that the means or products to control pollution must meet two conditions: a, long-term; B, can directly act on pollution sources. It is recommended to use more economical household deodorizing activated carbon here.

Adopt plant decontamination method.

Suitable indoor flowers and plants are: chlorophytum (including bluegrass), cactus (cactus), aloe, etc. These plants have a certain odor removal effect, which can eliminate some harmful substances left in the air. This method has the advantages of long-term, economy and beautifying the environment.

Spray decomposition of pure herbs.

This is a better and more effective removal method at present, and the prospect is very clear.

Extended data:

Formaldehyde, chemical formula HCHO or CH? O, molecular weight 30.03, also known as formaldehyde. Colorless, irritating to people's eyes and nose. The relative density of gas is 1.067 (air = 1), and the density of liquid is 0.8 15g/cm? (-20℃)。 Melting point -92℃, boiling point-65438 09.5℃. Soluble in water and ethanol. The highest concentration of aqueous solution can reach 55%, usually 40%. It is called formaldehyde water, commonly known as formalin, which is a colorless liquid with an irritating smell.

It has strong reducibility, especially in alkaline solution. Can burn, steam and air form an explosive mixture, and the explosion limit is 7%-73% (volume). The ignition point is around 300℃.

It can be prepared by dehydrogenation or oxidation of methanol under the catalysis of metals such as silver and copper, and can also be separated from oxidation products of hydrocarbons. It can be used as raw materials for phenolic resin, urea-formaldehyde resin, vinylon, urotropine, pentaerythritol, dyes, pesticides and disinfectants.

Industrial formaldehyde solution generally contains 37% formaldehyde and 15% polymerization inhibitor methanol, and its boiling point is 10 1℃.

2017101On October 27th, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization included formaldehyde in the list of carcinogens.
