Why does 90 of newly renovated homes exceed the formaldehyde standard?

With the continuous improvement of living standards, people are paying more and more attention to the health of their living environment, which has created more and more attention to indoor air pollution. Indoor air pollution mainly comes from decoration.

One. Panel furniture.

Most of the boards are made of multi-layer wood boards with adhesives, and there are four main adhesives used in the industrial production of wood-based panels: urea-formaldehyde resin, phenolic resin, melamine formaldehyde resin, and MDI. The raw materials of the first three contain formaldehyde.

We need to pay attention to its composition, if the formaldehyde exceeds the standard, you will be in a space surrounded by formaldehyde from all sides, health worries, so it is also necessary to remove formaldehyde from wallpaper.

Three. Floor. The formaldehyde treatment of the floor is also a main feature, the floor itself does not have formaldehyde, but the adhesive used in the installation process contains formaldehyde.

So how do you govern it?

Heiyan Pure Aldehyde Treasure is currently the product with the best effect on removing formaldehyde.

Heiyan Pure Aldehyde Bao is a purification material used in laboratories and other high-precision places, black and white particles. This year, it has gradually been welcomed in the field of civil formaldehyde removal. It has a large formaldehyde adsorption capacity, and the main advantage is that it completely decomposes formaldehyde, so it will not adsorb saturation, and formaldehyde will not be **.

The effective use period is more than 3 years.

In general, it is still necessary to be cautious about the purchase of various building materials with purification functions in the market, and it cannot be said that it is completely foolish, nor do it completely listen to what the business says. In short, removing formaldehyde after decoration is an effective way to control indoor pollution.

Why do I think 90% of newly renovated homes exceed the formaldehyde standard? This is due to the mess of substandard paints on the market. Some panel furniture also has excessive formaldehyde. This will cause formaldehyde to exceed the standard, which will cause harm to yourself.

The state stipulates the national standard for the release of formaldehyde in the home: the national standard of the People's Republic of China "Hygienic Standard for Formaldehyde in Indoor Air" stipulates that the maximum allowable concentration of formaldehyde in indoor air is milligrams of cubic meters.

The national standard of the People's Republic of China "Solid Wood Flooring" stipulates that the formaldehyde emission of Class A solid wood composite flooring is less than and equal to 9 mg 100 grams; The formaldehyde emission of class B parquet is equal to 9 mg - 40 mg 100 grams. "Technical Requirements for National Environmental Labeling Products - Artificial Wood Panels" stipulates:

The formaldehyde emission in man-made panels should be less than milligrams of cubic meters; The amount of formaldehyde released in wood flooring should be less than milligrams of cubic meters.

6 times.

The source of indoor pollution is more complex, and ordinary consumers should use comprehensive treatment methods such as photocatalysts as much as possible to improve indoor air quality. When signing a home improvement contract, it is best to add the air quality clause of the living room, so that residents can maintain their legal rights and interests when indoor air pollution problems occur after the renovation of the home. Before moving in, please ask the indoor environment testing unit to test the indoor environment, and only when the test results are lower than the national indoor environment standards, you can rest assured that you can move in.

Precautions for removing indoor formaldehyde.

Indoor formaldehyde removal can be removed by using the adsorption effect of activated carbon. Because there are many small holes on the activated carbon macro chain orange, after the activated carbon is placed in the room with formaldehyde, the decoration materials in the room continue to release formaldehyde substances, and the absorption of formaldehyde substances by activated carbon has a certain saturation, when it reaches a saturated state, the activated carbon will stop absorbing formaldehyde substances, so to ensure the good adsorption effect of activated carbon, the activated carbon should be replaced frequently.

Removal of indoor formaldehyde can not use the method of high temperature fumigation, some people like to put some vinegar in the newly decorated room for fumigation, thinking that under the action of high temperature, indoor formaldehyde will disappear, this idea is also very wrong, because indoor high temperature can not only eliminate formaldehyde, but also can promote the increase in the release of formaldehyde in decoration materials.

The above content refers to People's Daily Online-Formaldehyde Exceeding the Standard in Newly Installed Houses Indoor air inspection is very necessary.

Excessive formaldehyde is very serious, because high concentrations of formaldehyde may cause serious harm to human health, which may lead to respiratory diseases, ** diseases, eye diseases and other symptoms. Therefore, if it is found that indoor formaldehyde exceeds the standard, effective measures should be taken in time, such as ventilation, ventilation, air cleaning, etc., to reduce the content of indoor formaldehyde.

If the formaldehyde in the newly renovated home exceeds the standard by more than double, the following measures can be taken:

1.Ventilation: Open windows to maintain indoor air circulation and accelerate the volatilization and dispersion of formaldehyde.

2.Plant purification: Choose plants that have the ability to purify the air, such as spider plant, tiger tail orchid, aloe vera, etc., and place them indoors.

3.Activated carbon absorption and coarse adhesion: Activated carbon is placed indoors to adsorb formaldehyde molecules and reduce formaldehyde concentration.

4.Formaldehyde detection: You can purchase formaldehyde detection instruments to detect indoor formaldehyde concentration and take timely measures.

5.Decoration material replacement: If the formaldehyde exceeds the standard severely, you can consider replacing the fiber tank or reprocessing the decoration materials.

6.Professional services: You can seek professional indoor environment testing and treatment services to help solve problems.

Note: Aldehyde is a hazardous substance, and long-term exposure can have adverse effects on human health. Therefore, in order to protect our health, we must not only take the above measures, but also pay attention to hygiene and healthy habits in daily life.

The release of formaldehyde is a very slow process.

1. It is very important to pay more attention to opening windows and ventilation in the daily life of the remaining people in daily life.

2. You can also purchase an air purifier to remove formaldehyde.

3. Buying some activated carbon or bamboo charcoal can effectively adsorb formaldehyde.

4. Buy a few pots of green plants, such as pothos and spider plants, and place them at home.

Hello, happy to answer your questions. Newly renovated houses generally lead to excessive decoration pollution, which is normal, not only formaldehyde, but also some other volatile organic compounds. However, if you work or rest for a long time in a slightly oversized room, then the harm is also very large for a long time, do not think that the harm is small and careless, it is recommended that the newly renovated house should not be lived in immediately, open the window for ventilation, do some work in addition to formaldehyde, for physical safety, you must not be in a hurry to move in.

Hello, after the decoration of the new house, because the newly renovated materials and furniture will release harmful gases such as formaldehyde, measures need to be taken to remove formaldehyde. Here are some suggestions for removing formaldehyde:

1.Ventilation: After the decoration of the new house, you should open more windows for ventilation, keep indoor air circulation, and try not to use air conditioning. Through ventilation, indoor formaldehyde can be released to the outdoors to reduce indoor intensity. In general, ventilation should last from 2 weeks to 1 month.

2.Plant adsorption: Some plants have a certain adsorption capacity, such as aloe vera, spider plant, tiger tail orchid, pothos, etc., and placing them indoors can help absorb formaldehyde.

3.Activated carbon adsorption: Activated carbon is a material that can adsorb harmful gases such as formaldehyde, and some activated carbon can adsorb formaldehyde in the air and reduce the concentration of formaldehyde when placed indoors.

4.Cleaning and cleaning: After the renovation is completed, the room should be thoroughly cleaned and cleaned, including floors, walls, ceilings, furniture, etc., to reduce the content of harmful gases such as formaldehyde in the room.

5.Formaldehyde scavengers: There are some formaldehyde scavengers on the market, which can be sprayed on furniture, floors, walls and other items containing formaldehyde, effectively reducing formaldehyde concentration.

6.In addition to formaldehyde company: please remove formaldehyde company is now a more popular way to remove formaldehyde, should be a variety of indoor air pollution is OK, professional and technical personnel use professional agents and equipment for formaldehyde decomposition, the more common is to use the line of shouting green fast photocatalyst to remove formaldehyde, long-term effective decomposition of formaldehyde.

It should be noted that the process of removing formaldehyde requires patience and time, as the indoor formaldehyde concentration will gradually decrease over time. If you think formaldehyde concentrations in your home are very high or persistent, it's best to seek professional advice.

Aldehyde remover treatment formaldehyde construction.

1. Don't worry, you can leave it for a period of time for ventilation.

2. In the case of serious formaldehyde exceeding the standard, the national standard is to find a Chinese Academy of Sciences Indoor Environmental Monitoring Bureau to monitor it. If it is not serious, you can ventilate it first, put some activated carbon packets, and absorb the nano live ore. If it is serious, it will take a few simple measures.

3. If it is serious, it is helpful to use other ways and methods, such as spraying with some herbal removal sprays, and purifying the land with some purifiers.

Note: Do not use chemical ones, be cautious, many are secondary effects of withering.
