Is formaldehyde harmful in a newly renovated house?

There is definitely formaldehyde.

The first step: open the window for ventilation, the decoration has just ended, the pollution must be several times, dozens of times, or even hundreds of times exceeded, so the initial one to two weeks, what means are not very effective, the best way is to open the window for ventilation, as soon as possible to discharge the main indoor pollutants to the outdoors, in addition, in order to accelerate the indoor and outdoor air exchange, you can also use an electric fan.

Blow. Step 2: After the first step, the indoor pollution has become several times or almost not exceeding the standard from dozens of times, or even hundreds of times, and then the pollutants are emitted into a slow release process, no matter how you ventilate, it is impossible to remove them at once, then you must prepare for a protracted battle, you can use the following methods:

The first is flowers and plants, such as spider plants and cacti.

green plants, etc., such plants have a certain odor-absorbing effect, which can eliminate harmful substances in the air; The second is to buy some deodorants, these deodorants can be rubbed on furniture, which are said to have certain effects, such as chemical, biological, optical, etc., but the actual effect has not been tested personally, it is best to use it after careful inspection, and also pay attention to whether it is toxic, whether it will cause harm to furniture, etc. (it is said that some things will cause discoloration of furniture), whether it is convenient to use, etc. Of course, ventilation and ventilation must continue at this stage.

Step 3: After the second step, it's basically time to move in, at which point the ventilation and plant methods still need to be used, and activated carbon can be used.

Odor absorber to continue to absorb flavor, activated charcoal everyone knows, SARS.

The activated carbon masks worn by everyone during the period, and the gas masks worn by the renovation workers when spraying paint.

Activated carbon is used in household water purifiers or water purifiers, and activated carbon is mainly used in the industry, such as injection activated carbon, ** extraction activated carbon, special activated carbon for liquor purification, medicinal activated carbon, and blood purification.

Activated carbon, cigarette filter activated carbon, reagent activated carbon, etc.

The biggest advantage of activated carbon is that it is absolutely safe, reliable, useful, non-polluting, non-toxic, green and environmentally friendly, does not emit odor to the outside, and is inexpensive, economical and easy to use.

Yes. Generally speaking, when decorating a house, formaldehyde mainly comes from the following places:

1. Plates: All kinds of decorative ceiling boards contain formaldehyde substances because they have glue in them, especially plywood, compression board and particleboard.

2. New furniture: most of the furniture should be painted, and the paint itself also contains formaldehyde, and most of the furniture is made of synthetic board or other particleboard, and the formaldehyde substance in it is more serious than other decorative materials.

3. Flooring: Many friends hope to lay parquet flooring, but these floors are also one of the important sources of formaldehyde, because they will add formaldehyde to it in order to prevent moisture and increase wear resistance to prolong the service life of the floor.

5. Wallpaper wallcovering: The wallpaper wallpaper used to decorate the decoration is also a source of formaldehyde pollution, because both wallpaper and wallcloth need to use glue, as long as there is glue, there will be formaldehyde.

Newly renovated houses have a lot of formaldehyde.

Because formaldehyde mostly exists in decoration materials and daily use of furniture, such as common wooden floors, latex paints, paints, etc., as well as a variety of wooden furniture, in order to prevent cracking and smoothness, wooden furniture will be sprayed with a layer of glue to protect it, which is often an area where formaldehyde is gathered in large quantities. So just after the decoration, it happened to add a lot of furniture, and the house has more formaldehyde.

The volatilization period of formaldehyde is about 3-15 years, and the volatilization period of benzene and benzene series is about 3 years.

Newly renovated rooms and newly bought furniture are polluted, and the following methods are generally used to solve it. 1. Always maintain good ventilation to enhance volatilization. 2. Place more flowers and plants (aloe vera, spider plant, ivy, cactus, etc.) and activated charcoal (including inside the furniture) to absorb poisonous gases.

3. If possible, it is recommended to carry out indoor air testing, and ask professionals to deal with it. If the above methods are combined, the effect will be even better! For the sake of the next generation, it is best for pregnant women not to live in such rooms, and if they must live, it is recommended to share the above three methods, especially the third one, so that it is safe.

As for vinegar, pineapple, perfume, onion or other air fresheners, it is not good, because it only covers up the source of pollution, not cleans it up.

There is methanol, for example. In addition to plates, paints and adhesives contain formaldehyde in many decorative materials, such as latex, plastics, paints, coatings, etc.

Sometimes, even the most environmentally friendly materials are available, so it is necessary to open the windows for ventilation. Also have to wait a while before moving in.

After home decoration, some furniture will have some formaldehyde more or less.

Newly renovated houses definitely have formaldehyde.

The smell of the renovated new house is usually very big, and many families who decorate it will have doubts, saying that there will be pollution after the renovation of the new home, but the decoration pollution cannot be seen or touched, will it really have an impact on health, and the smell is pollution?

What is Renovation Pollution?

As long as the decoration, there will be pollution in the home, which is the release of decoration materials, no matter how environmentally friendly the decoration of your home is, there will be some pollution, but the specific pollution situation depends on the dose of pollutants. There are many common pollutants, formaldehyde, benzene, TVOC, etc. will have an impact on health, especially formaldehyde, which is a toxic pollutant and can cause disease if inhaled too much.

Where does formaldehyde pollution come from?

First, formaldehyde is used as preservative coatings, chemical fiber carpets, latex paints and other decorative materials;

The second is the adhesive of plywood, large core board, MDF and particleboard used in decoration materials and furniture, which will release formaldehyde when exposed to heat and deliquescent, which is the main source of formaldehyde release indoors;

The third is the glue used in home decoration, the main component of which is formaldehyde, such as putty glue for wall latex paint base, white latex used for pasting woodworking boards, and wallpaper glue in wallpaper.

Effective method 1: air purifier.

The air purifier has a fan-like device, and at the same time has a built-in filter, which can filter the indoor air, and can not open the window for ventilation or night time, it can be used instead of making up for ventilation, which has a good effect on removing the pollution of the confined space.

Effective method 2: Wipe down furniture.

Furniture is one of the main odors in the home, they mainly come from the wood paint inside and on the surface of the board, these harmful gases will be slowly released into the air through the surface of the furniture, clean water wiping the surface of the furniture, can take away part of the pollution attached to the surface of the furniture, to accelerate the removal of furniture odor has a certain help.

Effective method 3: spray spraying.

Furniture pollution is more difficult to deal with, the current mainstream effective method is spraying, the use of decomposition medium, algae spray such a class of natural spraying materials for furniture spraying treatment, the effect of removing furniture odor is obvious, it is not only safe and non-toxic, does not hurt furniture, and can penetrate the inside of the furniture plate, decompose formaldehyde from the source, and the speed and efficiency of purification are higher.

Effective method 4: Purification in small packets.

Formaldehyde repeatedly exceeds the standard is the most headache, the choice of algae sodium such adsorption plus decomposition materials, can be a good solution to this problem, it is different from the simple adsorption of carbon bags, can play a role in decomposing formaldehyde, will not appear adsorption saturation and then release the problem, can continue to decompose and purify for a long time, to ensure that formaldehyde is no longer the first after moving in. Therefore, we must be cautious in the selection of aldehyde removal materials.

Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, cause nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, gene mutations in the nucleus, DNA single-stranded cross-linking and DNA and protein cross-linking and inhibition of DNA damage repair, pregnancy syndrome, cause neonatal chromosomal abnormalities, leukemia, and cause memory and intelligence decline in adolescents. Of all those contacted, children and pregnant women are particularly sensitive to formaldehyde, which is a greater hazard.

Decoration and furniture are the main ones of formaldehyde. The formaldehyde release period in furniture panels is as long as 3-15 years, and it will volatilize from the deep layer of the material when it encounters heat and moisture, which seriously pollutes the environment and is a problem that cannot be ignored.

1. Open windows for ventilation. Ventilation is a must, and the content of formaldehyde, benzene, TVOC, etc. in the room can be quickly reduced through ventilation in the early stage; Even after a later move-in, frequent ventilation is required. After the new house is renovated, it is recommended to ventilate it for one year before moving in.

2. Ye Guang mud, activated carbon. The formaldehyde release cycle in furniture panels is very long, so ventilation alone is not enough to achieve the desired aldehyde removal effect. It is recommended to place some leaf mud and activated carbon in these places to adsorb formaldehyde and remove odors.

At the same time, in addition to adsorbing formaldehyde, Ye Guangni can also greatly and effectively decompose formaldehyde into water and carbon dioxide, which overcomes the problems that activated carbon will be released twice, easy to be saturated, and needs to be replaced frequently after adsorption saturation.

3. Photophyllin. For furniture boards, walls, and floors, photophyllin aldehyde removal spray can also be used to quickly form a film on the spraying surface, which can effectively decompose formaldehyde and effectively prevent formaldehyde from being released into indoor air.

4. Cultivating green plants. In the early years, the green plants can remove aldehyde blowing too much, green plants have the effect of absorbing formaldehyde and other harmful substances, but it is very limited, so in the removal of aldehydes can not rely too much on green plants, but for purifying indoor air and beautifying the indoor environment is still very good!

Building materials such as plates, coatings, and glues commonly used in the decoration of new houses may contain formaldehyde, so there will be a certain degree of formaldehyde release after the decoration of new houses. If the concentration of formaldehyde in indoor air is too high, it will have a negative impact on human health, such as causing symptoms such as headaches, throat discomfort, sore throat, eye pain, etc., and may lead to problems such as allergies. Therefore, after the decoration of the new house, it is necessary to pay attention to indoor ventilation, eliminate harmful gases such as formaldehyde, and maintain a good indoor environment.
