What can be used to solve formaldehyde in newly renovated new houses?
A, plant absorption method:

1, Ivy

Ivy is known as the champion plant to absorb formaldehyde, and it is the most effective indoor plant to absorb formaldehyde at present. The leaves of ivy can absorb 1.48 mg of formaldehyde per square meter, while the total area of leaves of two pots of adult ivy is about 0.78 square meters. At the same time, ivy can also absorb the toxic and harmful substance benzene.

2. Fuguizhu

Fuguizhu is helpful to improve the air quality in rooms where windows are not often ventilated, and it has disinfection effect. Especially in the bedroom, Fu Guizhu can effectively absorb waste gas.

3. Wealth Tree

It can effectively absorb the pollution of carbon monoxide and carbon dioxide, and has a certain effect on resisting the waste gas produced by tobacco combustion.

4. cactus

Cactus has a strong anti-inflammatory and bactericidal effect, and cactus is the best plant to reduce electromagnetic radiation in pollution treatment.

5, green radish

Green radish has strong vitality and strong ability to absorb harmful substances, which can help improve air quality in rooms where windows are not often ventilated.

6. aloe oil

Potted aloe vera is known as an expert in air purification. A pot of aloe is equivalent to nine biological air purifiers, which can absorb harmful substances such as formaldehyde, carbon dioxide, sulfur dioxide and carbon monoxide, especially formaldehyde.

7. The Silver Queen

The higher the concentration of pollutants in the air, the more it can exert its purification ability! So it is very suitable for dark rooms with poor ventilation.

8. Chlorophytum

Chlorophytum can carry out photosynthesis in weak light, and Chlorophytum can absorb toxic and harmful gases in the air, such as carbon monoxide and formaldehyde mixed in the air, which can reach 95% and 85% respectively. Chlorophytum can also decompose benzene and absorb relatively stable harmful substances such as nicotine in cigarette smoke, so Chlorophytum is also called the green purifier of indoor air.

Second, activated carbon adsorption method

1, environmental protection packaging: cut the old clothes and cloth into squares of 22*22CM or 28*28CM, put an appropriate amount of 60 or 100g activated carbon into the cloth, grab the shrunk cloth edges, tie them with ropes, and put them in various pollution sources or needed places.

2. Decoration and deodorization. Initially, the activated carbon bags in different positions were replaced every few days to accelerate the absorption of harmful gases in different spaces.

3. When the indoor harmful gas is basically absorbed, please continue to wrap the activated carbon in the corner of the house or furniture to absorb the residual harmful gas.

4. When used for a long time, in case of wet weather or after several months of use, the activated carbon can be taken out and exposed to the sun for a whole day, and the activity can be recycled.

Please keep the activated carbon sealed for three years.

Third, black tea in addition to formaldehyde

300 grams of black tea is soaked in two washbasins of hot water, put in the room, and open the window for ventilation. Within 48 hours, the indoor formaldehyde content decreased by more than 90%, and the pungent smell was basically eliminated.

Fourthly, the utilization of fly ash.

Prepare 400g coal ash, repackage it with washbasin, and put it in the room where in addition to formaldehyde is needed. The formaldehyde content can be reduced to a safe range within one week. The above methods are also applicable to families with no odor after decoration, because some harmful substances are colorless and tasteless, and the cleaner they are, the safer they are.

Other in addition to formaldehyde methods.

1, plant-derived air purification liquid

China has used plant source disinfection and sterilization for more than 3000 years. AQ air purification spray uses special plant extracts, and attacks bacteria in the air by using the active ability of its own terpenoid sesquiterpene organic compounds, resulting in hypoxia of bacterial cells and death of bacteria. This plant itself has a certain smell and stays in the air. Once the oxidation process is completed, the smell will soon disappear. Unlike other plant essential oils, they don't last long. Terpenoids, the effective components, surround, oxidize, decompose, remove or harmlessly treat harmful pollutants such as aldehydes, benzenes and ethers at the same time, increase the content of available oxygen in the air, and obviously improve the function of human respiratory system. It can quickly decompose oxidized odor and odor molecules, kill putrefaction and odor-causing microorganisms, and release plant-derived aroma factors, which not only eliminates odor sources, but also increases air freshening effect.

2, formaldehyde scavenger or formaldehyde dissolving enzyme

Formaldehyde scavenger "removes" formaldehyde through chemical reaction, the essence of which is to reduce the toxicity of the target substance or convert it into non-toxic substance. Formaldehyde can be oxidized to formic acid or reduced to methanol. Although the toxicity and irritation of these two substances are lower than formaldehyde, their toxicity still exists. For example, some highly oxidizing formaldehyde scavengers can oxidize formaldehyde, but they are easy to decompose by themselves. Spraying on the board will damage the wood, and it will be ineffective within a few hours. It is impossible to "spray it to the end". In addition, the high concentration scavenger sprayed in the air will cause new pollution hazards to people. Other oxidants and reductants can not effectively remove formaldehyde, and will also introduce similar new pollution.

Several steps to clean up indoor pollution after decoration

Step 1: Open the window for ventilation. 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 in the early one to two weeks is to open the window for a long time to ventilate, 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.

Step 2: Use decoration deodorizing 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. As for activated carbon, as we all know, during the SARS period, people wore masks, gas masks worn by decoration workers when painting, household water purifiers or water purifiers, and activated carbon fiber filter layers in air purifiers all used activated carbon.

Step 3: adopt plant decontamination method. Suitable indoor flowers and plants are: chlorophytum (including bluegrass), cactus (cactus family), 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.
