How to remove formaldehyde has the best effect, how to remove formaldehyde has the best effect

1. Open more windows and ventilate the room.

In fact, this method should be the most effective, and it is also the best way to use. Now after the decoration of the new house, there will be some formaldehyde more or less, because the raw materials and some boards of the decoration do contain formaldehyde. The volatilization period of formaldehyde is relatively long, usually about 10 years, so the newly renovated new house must keep indoor ventilation, as long as the indoor ventilation performance is good, then formaldehyde will be discharged to the outdoors, of course, this may take a certain amount of time, not a day or two can be completed.

02. Use some green plants to remove formaldehyde.

Nowadays, many green plants will have this function, for example, we have spider plants, tiger pill orchids and pothos and so on. The vitality of these green plants is relatively tenacious, and they are usually relatively easy to take care of, and the most important point is to remove formaldehyde indoors. Of course, the use of green plants to remove formaldehyde has a certain effect, but it is not obvious, so while using green plants to remove formaldehyde, we also need to use other methods to cooperate.

03. Activated carbon can adsorb formaldehyde.

This should also be a more common means, because activated carbon can indeed adsorb formaldehyde and some other harmful gases, so you can buy more activated carbon, and then put it in every corner of the room, usually about 2 3 months, these activated carbon can effectively adsorb formaldehyde in the room.

04. Find a professional formaldehyde removal company and use professional products to remove formaldehyde.

Now there are many more professional companies that can directly remove formaldehyde, because they have a lot of more professional equipment and products, using these professional equipment and products can quickly remove formaldehyde in the house. Of course, the fees of these companies are usually relatively expensive, and the ** of these products is usually quite high, so if you are not particularly anxious to move in, I personally do not recommend using this method.

Changes in indoor formaldehyde concentrations over time under different methods:

1.The continuous ventilation method can continuously transport the formaldehyde released by the board out of the room, so the indoor formaldehyde concentration is also the lowest;

2.The smouldering method will only allow formaldehyde to accumulate indoors, and the accumulation is getting slower and slower, and the rise rate of indoor formaldehyde concentration is basically zero after 20 hours, and it also shows that the doors and windows have been closed, and the volatilization rate of formaldehyde will be inhibited, or it will not be released at all;

Case in point: just like drying clothes on a damp rainy day, the wetter the clothes, the harder it is to dry.

Therefore, the suffocation method that is now widely circulated has no scientific basis at all, so don't blindly believe it.

Formaldehyde has three manifestations in the plate: free state, unstable adsorption state, and complex state. The amount of free and adsorbed states in space is related to many physical parameters

Temperature, pressure, air volume, humidity, etc. That's why if you want to speed up the volatilization of formaldehyde, you need to increase the indoor temperature and humidity!

High concentration will inhibit the volatilization of formaldehyde, in the summer to insist on 24 keep the window open for ventilation, because the outdoor temperature is higher than indoors, at the same time, we should also pay attention to the ventilation skills in other seasons, for spring and autumn, indoor and outdoor temperature and humidity are not much different, ventilation is still the best choice!!

Professor Zhang Pengyi of Tsinghua University expressed the ventilation point of view, which is also to keep the windows open for ventilation!

There is another point that needs to be expressed: in the short term, the harm of animonia TVOC and radon is not less than formaldehyde, and it should not be underestimated.

Formaldehyde: "no formaldehyde, no glue".

Benzene: "No benzene is not lacquer", and most of the odors usually smelled are volatile organic compounds such as benzene TVOC.

Ammonia: an additive for building construction concrete, more commonly used in the north.

Summary:1Open windows for ventilation (should come first).

The above is also a detailed analysis of this, and it is also the most economical and effective way, but the only drawback is that the speed is too slow, and the poor ventilation of the room or dead corner has little effect.

2.Increase temperature and humidity.

There is no increase in indoor temperature and humidity as much as possible before moving in, and the volatilization rate of formaldehyde is accelerated, which is why it is recommended that after a summer high temperature, there is a scientific basis, and it is best to install a fresh air system, which can more effectively discharge indoor gas outdoor, 3Decomposition and physical adsorption.

The methods of chemical decomposition include hydrogen peroxide, chlorine dioxide, etc., and this method used by the formaldehyde company is effective in a short time; The most typical physical adsorption method is a variety of activated carbon, which has a weak effect and secondary pollution.

How to remove formaldehyde at home?

Opening windows for ventilation is the best effect, nothing else is good, the effect is very small. Hardly.

I don't know if you will have a confusion, that is, the smell of the Himalayan house will be very strong, that is, the pungent smell is formaldehyde, formaldehyde is the smell of materials left over from the use of paint and other materials during decoration, and these smells are very harmful to the human body. So how to effectively remove formaldehyde?

First, the most economical and practical way is to open the windows to allow air

This is generally done by everyone, because when a new house is bought, everyone will think of opening all the windows to allow the air to flow, but everyone will ignore a problem that cabinets and cabinets, and now there are boxes where they are closed, they also need to open it so that all the air can circulate.

And the most suitable is a kind of convective air, so that the air can be fully and completely converted, and formaldehyde can be removed. However, this method is only suitable for the removal of most of the formaldehyde in the house, and for some relatively hidden and small corners, this method is actually not very usable.

Second, if you want to remove formaldehyde in the house, small corners and hidden places, you can buy some activated carbon

Activated carbon has now become a more well-known thing, because sometimes in order to remove the odor from the car, everyone will buy an activated carbon bag and throw it on the car.

Activated carbon can adsorb formaldehyde and is also non-toxic and harmless, so it is a good way to purchase some and put it in a small place.

Third, it is also a good way to buy some fresh plants and put them in the house for formaldehyde adsorption

Fresh green plants, they have a certain effect on the adsorption of formaldehyde, especially like aloe vera, saxifera and spider plant.

This job has an adsorption effect on formaldehyde, and in addition to this, they can also be used as a decoration for a new home. The fresh green color gives the home a fresh and comfortable feeling. At that time, the teacher bought a new house, so he chose this easiest method, bought a lot of plants and put them in his home, and absorbed them for more than a month before officially moving in.

Green plants can also absorb harmful gases such as carbon dioxide, they play a very large role, and they are used as decorations throughout the home, which can not only fresh the air but also decorate the home, which is also a thing that kills two birds with one stone.

1. Chlorine dioxide effervescent tablets are placed in a disposable cup filled with water 2. Activated carbon 3. Photocatalyst sprayed on walls and furniture 4. Green plants 5. Open windows for ventilation.

Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced, thereby reducing the harm of such substances to the human body. In winter, people often close doors and windows, indoor and outdoor air can not circulate, not only the content of formaldehyde in indoor air will increase, radon will also continue to accumulate, and even reach a high concentration.

There is a person named Caihui who is not bad, I have bought his spray, the effect is very good, and it has not left a mark.

To remove formaldehyde after home decoration, you can ventilate it for a month first, and then look at the actual situation. Hope it helps. Here are some things you can try:

1. Keep ventilation at all times and take away harmful gases such as formaldehyde through air flow.

2. Long-term planting of plants, plants that can absorb formaldehyde, such as: spider plant, aloe vera, tiger tail rot, cactus, etc.

3. Adsorb formaldehyde with physical absorption, put some leaf wide mud, activated carbon material.

4. Use photocatalyst, but it cannot be eliminated where there is no light.

5. Photophyllin, extracted from the plant body, increases photosensitivity, decomposes formaldehyde 6, grapefruit peel, aged vinegar, etc. to remove peculiar smells. Then wipe the furniture with salt water.

1. The cost-effective aldehyde removal products in the industry, the CADR value in the same time is far higher than that of the fresh air system, and the household aldehyde removal products are very suitable.

2. The air purifier and fresh air system are active formaldehyde removal, which can accelerate the airflow speed, improve the air exchange rate (air exchange rate), and at the same time, the filter absorbs part of the formaldehyde and effectively reduces the formaldehyde content.

3. The pores of activated carbon have adsorption potential, which is mainly formed by the gravitational action between carbon molecules and adsorbed molecules, the smaller the pore size, the greater the adsorption potential, so activated carbon is effective in the initial stage.

4. The principle of photocatalyst is to use titanium dioxide as a catalyst to decompose formaldehyde under light conditions.

Extension: Formaldehyde is actually very common, especially a variety of formaldehyde-based resins, widely used in the construction and textile industries, such as composite panels to make floors, cabinets, wooden doors, adhesives on furniture, paints, wall paints, textiles (fabric sofas, curtains), etc.

In winter, choose a warm afternoon, when the sun shines into the room, do not ventilate for too long each time, to prevent the walls near the windowsill from freezing and discoloring or freezing because the room is too cold. If you have heating equipment in your home, such as air conditioning, floor heating, etc., you can close the windows for a period of time before opening them.

Summer is the best time to remove formaldehyde. In summer, the light hours are long and the temperature is high, which makes it easier to release formaldehyde. (Turn it off for a period of time to let the formaldehyde release out for better ventilation.) )

Newly renovated houses should be ventilated for a period of time to disperse the smell of paint. Later formaldehyde treatment for furniture sitting:

1. Wipe the furniture with salt water, remove the taste, and put a few packets of Ye Guang mud into it to absorb formaldehyde, which can decompose formaldehyde, so it will not adsorb saturation.

2. In summer, the temperature is high, and formaldehyde is released, and more ventilation can ventilate part of it. If you do it quickly, you can treat it with the extract of the plant.

3. Plant absorption can also be, but the effect is slow, tiger pill orchid, aloe vera cactus is still very beautiful at home.

4. After removing it, you can see if there is still a smell, and the test is finished. It is possible to live below the standard.

If you want to have medium and low pollution, you can choose plant decontamination: generally indoor environmental pollution is light and moderate pollution, and the pollution value is less than 3 times the national standard, and the use of plant purification can achieve better results. Choose and place plants according to the different functions and sizes of the room.

1. Use activated carbon and windows for ventilation. The gravity of the carbon molecules and adsorption molecules of activated carbon forms an adsorption type, so the smaller the pore diameter, the stronger the adsorption type, the structure of activated carbon is characterized by many pores and strong adsorption force, and many disinfection masks are made using this characteristic of activated carbon. It is best to choose activated carbon with smaller particles.

The smaller the particles, the better the adsorption effect. Second, open windows frequently for ventilation to strengthen indoor and outdoor air convection, which is also very effective.

2. Use formaldehyde scavengers or formaldehyde lyssing enzymes. Removal of formaldehyde cleaner formaldehyde is to chemically reduce formaldehyde toxicity or convert it into a non-toxic substance. Formaldehyde removal dissolving enzyme formaldehyde is the penetration of this enzyme into the plate material to remove harmful gases.

Fresh air system. It is to use the function of ventilation to continuously discharge the indoor formaldehyde dirty gas out of the outdoors, and at the same time send the fresh air into the outdoor car through the machine to ensure the freshness and cleanliness of the indoor air.

How to effectively remove formaldehyde in new houses, has been a problem that bothers everyone, there is too much false information on the market, and it makes people choose one head and two big, I don't know which one is true and which one is fake, the following is an introduction to several commonly used small methods of removing aldehyde for you to choose.

1. Wise Stone.

It is a very popular purification product on the market in recent years, the main reason is that it has the dual function of absorption and decomposition, can actively absorb free formaldehyde in the air, and do not have to worry about the impact of external factors such as temperature, humidity, light, etc. The adsorbed formaldehyde will also be decomposed into water and carbon dioxide and discharged from the body, without drying and no secondary pollution. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

2. Ventilation.

Ventilation is an indispensable method of removing formaldehyde indoors, but when the outdoor wind is not strong enough, it is necessary to strengthen ventilation. At this time, you can buy a high-power industrial fan to assist in the removal of harmful gases in the house, which can accelerate the circulation of air inside and outside the house, which is of great help to remove indoor decoration pollution.

3. Activated charcoal.

Activated carbon is a traditional physical adsorption material, which has been well received in the treatment of indoor and outdoor pollution, its specific surface area is large, and it has a strong adsorption capacity, but its adsorption capacity is limited, and it does not have the function of decomposition

4. Formaldehyde remover.

Under certain conditions, formaldehyde scavengers react chemically with formaldehyde to produce other substances that are not harmful to health, so as to reduce the concentration of formaldehyde in the room. But it's also a chemical in its own right, and if used incorrectly, it can be another source of pollution indoors.

Fifth, high temperature.

We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that a large amount of formaldehyde gas can be volatilized, and then formaldehyde can be removed by opening windows for ventilation. Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire.

Formaldehyde is a high-ranking toxic substance, but also a potential carcinogen, before moving into a new house to remove formaldehyde is an urgent job, according to the above, can be selected to choose a variety of methods at the same time.
