In addition to formaldehyde after the renovation of the new house

Formaldehyde is the most serious harmful gas in indoor decoration, which comes from decorative materials such as wood-based panels, furniture, wall covering, wallpaper, paints and coatings used in indoor decoration, and its release time is 5- 10 year. At present, according to the indoor environmental testing department, there are different levels of formaldehyde pollution in newly renovated families. Introduce the following in addition to formaldehyde methods:

1, common soil trick:

300 grams of black tea is soaked in two basins of hot tea, put it indoors, and open the window for ventilation. Within 48 hours, the indoor formaldehyde content decreased by more than 90%, and the pungent odor was slightly eliminated.

2, ventilation method to remove formaldehyde scheme:

Through the circulation of indoor air, the content of some free harmful substances in indoor air can be reduced, thus reducing the harm of such substances to human body, but the symptoms are not cured. People often close doors and windows in winter, so the indoor and outdoor air can't circulate. Not only the content of formaldehyde in indoor air will increase, but also radon gas will accumulate continuously, even reaching a very high concentration.

3, activated carbon adsorption method:

Activated carbon is a common in addition to formaldehyde method in general families, and its principle mainly depends on the adsorption principle of activated carbon to adsorb indoor harmful gases to activated carbon. However, it should be reminded that the pollution level of each room is different. When activated carbon is saturated, new activated carbon products should be replaced in time; If it can't be replaced in time, the saturated activated carbon will release harmful gases adsorbed before, which is likely to cause serious secondary pollution.

4, in addition to furniture formaldehyde smell method:

You can go to the market to choose some high-tech deodorizing cleaners, which can remove the harmful gases emitted by newly renovated houses and new furniture. According to relevant sources, these deodorizing cleaners are generally imported products, which use ammonia compounds to react with harmful substances to deodorize and clean. In the newly renovated room, you can pour this deodorizing cleaner into a plate, put the plate in each room separately, and combine with the method of scrubbing and deodorizing to effectively remove the unpleasant smell in a few days;

You can put two pots of salt water indoors, and the smell of paint will soon disappear. If it is the smell of paint from wooden furniture, you can scrub it with tea for several times, and the smell of paint will be eliminated faster;

To quickly remove the residual paint smell, you can soak cotton balls in citric acid and hang them indoors and in wooden furniture.

5, plant deodorization method:

Plant purification can be selected for medium and low pollution: generally, indoor environmental pollution is light and moderate, and the pollution value is less than twice of the national standard, and plant purification can achieve certain results. Choose and place plants according to different functions and areas of the room. Generally speaking, it is more appropriate to put two pots of plants with a height of 10 square meter in a room with a height of10 meter. (Recommended: Chlorophytum, Aloe Vera, Hupilan)

Second, how long can I live after renovation? It is best to carry out indoor formaldehyde testing after renovation. The inspection shall be arranged at least 7 days after the decoration and renovation are completely completed. The concentration of volatile pollutants is the highest within 7 days, and it can basically drop to a stable state after 7 days, which is the best stage of detection. At the same time, the longer the external doors and windows are closed, the higher the indoor pollutant concentration. Formaldehyde self-test box or tester can be used for formaldehyde self-test. Formaldehyde in the air reacts with phenol reagent in the test chamber to generate triazine substances, and then forms blue-green compounds with iron oxide. Finally, the content of formaldehyde is judged by the contrast of color depth. According to the national regulations, the indoor content shall not exceed 0. 1 mg/m3.

Experts said that the renovated room should be well ventilated for 3 months, so that volatile harmful gases can be released as soon as possible, and then you can move into a new home. However, only 80% of the houses can move in after three months, and 20% will take longer. You know, many harmful substances are colorless and odorless, but no smell or peculiar smell does not mean no pollution. For example, the pungent smell of benzene series is not big, but it is very harmful to human body; Radioactive gas radon is tasteless, but it can cause lung cancer.

Tips: If there are pregnant women, the elderly, children and other special groups at home, and the decoration materials are not good, it is best to pass a comprehensive inspection and move in after half a year. Because special people are fragile and sensitive, it is recommended not to live in a new house from the beginning. Nowadays, many young people are newly bought houses and move in as soon as they are renovated. They feel that with their own house, they finally have their own private space. In fact, doing so poses a very serious safety hazard to health.
