Formaldehyde is the number one killer of decoration pollution. There are many methods to control formaldehyde, but not many effective ones. Therefore, formaldehyde must be eliminated at the source, together with auxiliary tools to remove formaldehyde

first, prevention: carefully select household building materials products and sign environmental protection decoration contracts

the so-called " Prevention is better than governance ", If the owners can have the awareness of preventing formaldehyde pollution from the beginning of decoration, they can start from many aspects and curb the excessive release of formaldehyde at the root. Formaldehyde prevention requires the following points:

1. Advocate simple decoration

try to reduce the use and construction of decoration materials, because in the same space, the simpler the decoration, the less furniture placed, and the less pollution pressure caused to the space. In addition, it is best not to stick wallpaper that will emit pungent odor in the children's room, and try not to pave plastic floors, which may release a large number of volatile organic substances and increase the degree of indoor pollution

2. Pay attention to environmental protection materials and furniture

the paint of children's room is best to choose water-based, and the color should not be too bright. The brighter the paint, the higher the pollutant content may be. Buy children's furniture to choose solid wood furniture, decoration how to save money? On, free design budget quotation. And ensure environmental protection monitoring report. Furniture cannot have strong pungent smell, because the greater the pungent smell, the higher the formaldehyde emission

3. Sign an environmental protection decoration contract

when designing the decoration, the owner can choose to negotiate and sign an environmental protection decoration contract with the decoration company. The contract requires the construction party to provide an indoor environment inspection report stamped with CMA seal after completion, so as to urge the decoration company to carry out environmental protection decoration. Before decoration, it is also necessary to predict the concentration of harmful substances released in the indoor environment after decoration, and reserve a certain floating space for the release. Because even if the indoor environment meets the standard after decoration, the furniture may also release a certain amount of formaldehyde pollutants after placement

II. Treatment: pay attention to ventilation and ventilation after decoration, and use effective methods to reduce formaldehyde pollution

if some owners have finished decorating the house and have not subconsciously controlled the pollution source, is it irreversible? It's not. The phenomenon of formaldehyde pollution during decoration is widespread. Therefore, if we can carry out targeted treatment in a scientific way in the later stage, we can also minimize the pollution of formaldehyde

1. Temperature, high humidity, ventilation and ventilation

the newly decorated room should not be moved in immediately, but should have a certain time to let the formaldehyde in the material be distributed with a higher intensity. The volatilization rate of formaldehyde is closely related to indoor temperature, humidity and wind speed. If the indoor environment can be scientifically adjusted, high temperature, high humidity and large air volume can better promote the volatilization of formaldehyde

2. Substance absorption method

many plants have certain absorption ability to formaldehyde, such as cactus, Chlorophytum comosum, aloe, Clivia, iron tree, chrysanthemum, etc. among them, Chlorophytum comosum is an expert in removing formaldehyde, which can absorb 86% of formaldehyde within 24 hours and purify the air within 8 to 10 square meters. Others like to put tea dregs, grapefruit peel, onion slices, pineapple pieces, etc. in the newly decorated room, or fumigate the room with white vinegar to eliminate the smell of formaldehyde

3. Carbon adsorption method

solid activated carbon has the characteristics of many voids, and has a strong adsorption and synthesis effect on harmful substances such as formaldehyde. The smaller the particle of activated carbon, the better the adsorption effect. The adsorption effect of activated carbon on formaldehyde is obvious. According to the size of the room, the amount of activated carbon should be different, and it should be replaced in time after use for a period of time

4. Chemical treatment method

at present, the air purifiers in the market are divided into anion type, ozone type, filtration adsorption type, etc., and different varieties have different working principles. The air purifier can absorb harmful gases quite effectively, but the air purifier can only be used in closed space. If the window is open, the application effect will be greatly reduced

5. Chemical preparation purification method

mainly consumes formaldehyde in the air through physical adsorption or chemical reaction; At present, there are two kinds of formaldehyde capture agents on the market. One is to purify the air by neutralizing formaldehyde and generating harmless substances; The other is to purify the air by blocking formaldehyde and preventing its volatilization. Using chemical agents to eliminate formaldehyde is efficient and effective, but the release of formaldehyde is a long-term process, which should be avoided; Treat the root cause but not the symptoms " The phenomenon of

III. suggestions: the use of air purification devices can effectively absorb and decompose harmful gases

if the home has just been decorated, don't move in immediately. Leave the house empty for more than half a year for ventilation before you can live. For the treatment of formaldehyde, we should deal with the source of pollution. The sources of air pollution in home decoration mainly include furniture, wallpaper, paint and solid wood flooring. When necessary, air purifiers can be used to purify formaldehyde more pertinently and quickly and effectively. Now commonly used activated carbon filters can effectively absorb and decompose harmful gases, such as formaldehyde, toluene, TVOC, etc
