What are the effective ways to remove formaldehyde and decoration odor?

1. The principle of formaldehyde removal of activated carbon and nano mineral crystals is physical adsorption, and formaldehyde is adsorbed through its own special pores. The effect of this method is well known and very weak. The increase in temperature will also release the formaldehyde that would have been absorbed, causing secondary pollution.

Merchants will also claim that they can be reused after exposure, but in fact, the effect will be greatly reduced, and it will become a waste, so it is better to throw it away.

2. The most important thing about diatom mud and shell powder diatom mud is not that it can absorb formaldehyde, but that it does not release formaldehyde itself, and it is an environmentally friendly material. But the formaldehyde adsorption capacity is really poor, and it is not as good as activated carbon. The main ingredient of shell powder is calcium carbonate, which can absorb formaldehyde?

Fool it! 3. The main component of photocatalyst photocatalyst is titanium dioxide, also known as photocatalyst, which is irradiated with ultraviolet rays in the laboratory, which does have an effect on formaldehyde. But it can't be used in the living room, we can't buy a UV lamp to irradiate it, right? It is not realistic for the elderly and children to spend most of their time indoors.

Don't think about spraying photocatalyst on the window, ultraviolet rays can't penetrate ordinary glass, if the window is opened, the ventilation effect is better, why do you need photocatalyst? There are also nano photocatalysts to add other ions, some say that it can decompose formaldehyde under visible light (the effect will definitely not be high), we don't talk about this, the nanoparticles themselves are very harmful to the human body, and the polymerization of nanoparticles in the air is a big problem. Even if these problems are solved, the cost is also an issue, and this product will definitely not be cheap.

4. I didn't want to say anything about adding a plant to you, I feel that most people know its effect, but you really use plants to remove formaldehyde. Common green plants in addition to formaldehyde in daily life are: pothos, spider plant, agave, ivy and other plants.

Liao Qiushi and other professors conducted comparative tests on ivy, pothos and activated carbon in closed boxes in "The Effect of Activated Carbon and Plants on Formaldehyde Purification in Indoor Air". Experimental data on the absorption rate of formaldehyde after one day of treatment showed that Ivy (; Pothos (; Activated carbon (.

After 10 days of treatment, the data showed that Ivy (; Activated carbon (. Pothos (;

The treatment of formaldehyde can not use the principle of physical adsorption, but can only be decomposed by oxidation. In addition to formaldehyde, the company commonly used hydrogen peroxide, which is the kind of formaldehyde treatment for a week. We can usually buy some purple and black, for formaldehyde is chemical decomposition, what happens is redox reaction.

Formaldehyde is decomposed into carbon dioxide and water, and the violet-plus-black product itself turns black. The ordinary three-room is only two or three hundred yuan each time, but it needs to be replaced regularly, and it is useless to turn completely black. This is also the latest method principle recommended by CCTV this year, and the relevant departments of the state may also look at the formaldehyde removal industry too chaotic.

2. Try to install the fresh air system before the decoration of the fresh air system, and the system is basically about 20,000 yuan. In addition to formaldehyde, the effect is good, if you have money, you can directly install one, it is best to choose a big brand, the fan has a long service life. You can choose the best fresh air system for installing a fresh air system, and don't choose a wall-mounted one.

The wall-mounted type is limited by thickness and aesthetics, and the purification efficiency is too poor.

The new home has a taste, and it only takes three steps to say goodbye to formaldehyde pollution after moving home.

Furniture odor mainly comes from the wood paint inside and on the surface of the board, they release slowly and the release cycle is relatively long, so there has always been a problem in removing furniture odor, that is, only the surface pollution released can be removed, and the internal pollution can not be removed deeply, which will lead to the purification process, the smell may come out again after a while, so in view of this situation, I have sorted out the common treatment methods used by environmental protection engineers, and I recommend that you can deal with it from the following three steps, Whether it is surface pollution or internal pollution, it can achieve a good purification effect.

Step 1: Open the windows and ventilate the furniture.

Ventilation is the simplest and most effective way to reduce indoor pollution, except for the weather reasons that can not open the window, we should cooperate with the window ventilation in an appropriate amount, and all the furniture doors should be opened at the same time as ventilation, which helps to accelerate the odor in the furniture, and has a good help to remove the furniture odor that has been released.

Step 2: Spraying decomposition medium penetrates and decomposes.

The pollution inside the furniture plate is the most difficult to remove, but this is not difficult for environmental protection engineers, they usually use natural decomposition media to spray the inside and outside of the furniture, the natural decomposition medium itself is safe and non-toxic, and will not cause any harm to the human body and furniture, and it has the effect of osmotic induced decomposition, which can penetrate into the interior of the furniture plate to decompose, that is, it can be treated from the source, so it can play a very good purification and deodorization effect.

Step 3: Long-term adsorption and decomposition of algae.

The release cycle of formaldehyde and other pollution is as long as 3-15 years, in order to achieve better and faster results, and at the same time avoid the formaldehyde that may appear in the later stage**, properly place some algae sodium packets in the furniture, which can continue to adsorb and decompose the harmful gases released by the furniture, and the algae can decompose formaldehyde, so there is no need to worry about adsorption saturation, and there is no need to dry it in the furniture, and it is more convenient to use.

1. Ventilation.

No matter what season it is, it is very necessary to keep the windows open for ventilation, especially for newly renovated houses, only long-term ventilation can effectively reduce the content of toxic gases in the room.

2. Plant absorption.

If the home is only moderately low formaldehyde pollution, plant removal can be chosen. Generally, the type and number of plants are selected according to the purpose and size of the room.

3. Air purifier.

Air purifiers have a strong purification ability, air purifiers are divided into several types, there are special machines for purifying the air and removing formaldehyde after the decoration of the new house, which can remove indoor odors, formaldehyde and other harmful objects, so that the family can breathe fresh air.

4. Activated carbon adsorption.

As we all know, activated carbon has a strong adsorption capacity for formaldehyde and benzene harmful gases, but the placement of activated carbon is also particular, otherwise it will not work, the correct way is to place 50g of activated carbon per square meter, so as to completely remove formaldehyde indoors, and improve indoor air quality.

How long will it take to move in after the new house is renovated? How to quickly remove formaldehyde and odors.

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. In the new home, you can prepare more points and put them in every corner to adsorb them, which can prevent excessive formaldehyde in the later stage.

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. Formaldehyde is soluble in water, and it is recommended to use a cup with a lid at home.

In a newly renovated house, if you want to remove formaldehyde, you need to do the following:

1) Open the windows to keep the house ventilated and breathable, and bring formaldehyde out of the room through the flowing air;

2) You can put some green plants such as pothos and ivy to help absorb formaldehyde in the room, but at the same time, every three days, you need to put these plants on the sun platform to facilitate their release of toxic and harmful substances;

3) You can buy some activated carbon and put it in the cabinets, drawers and other places in the room to help adsorb various toxic and harmful substances, and it will not affect the normal use of furniture. If the activated charcoal is exposed to the sun every other week, its effect can be reused;

4) You can also use Ye Guangni to keep it ventilated for a week.

Method 1: Open the window for ventilation.

Ventilation can quickly reduce the formaldehyde concentration in the home in a short period of time, and at the same time can take away the pungent odor in the house, and the effect is immediate, so you should open the windows frequently for ventilation after decoration. However, this effect is only temporary, and it will be ** when the window is closed, because the volatilization period of formaldehyde is very long, which can reach 3 15 years, and it cannot be completely solved by ventilation alone.

Method 2: Air purifier.

Although opening windows and ventilation to remove formaldehyde has a short-term effect, but the limitations are too great, so it should be used together with other methods to better control formaldehyde, such as professional formaldehyde removal air purifiers, which can not only efficiently adsorb formaldehyde, but also decompose formaldehyde into carbon dioxide and water, completely eliminate the secondary pollution of formaldehyde, and let us enjoy a fresh and healthy breathing environment.

Method 3: Aldehyde removal spray.

Aldehyde removal spray is a new type of tool specifically for formaldehyde. However, this method is to treat the symptoms but not the root cause, and the film will also be destroyed because of our daily activities, so the formaldehyde will volatilize again, so it needs to be sprayed regularly. Moreover, the aldehyde removal spray also has a certain chemical composition inside, although it is harmless to the human body, it is also recommended that you use it sparingly.

Method 4: Activated carbon.

Activated carbon has strong adsorption capacity, but it is also easy to be full, and after adsorption to a certain extent, it needs to be replaced with new activated carbon, because it no longer has adsorption capacity. Activated carbon is now widely used in handicrafts, and it can also remove formaldehyde while looking good.

Methods of removing formaldehyde:

1. Open window ventilation method: After decoration, you must open more windows for ventilation, no matter what you use to remove formaldehyde, you still have to keep more ventilation, this is the most effective.

2. Diallin decomposition: photocatalysts and other photocatalysts can decompose formaldehyde when exposed to light, and there are more industrial applications for removing formaldehyde, and diarin is a formaldehyde catalyst extracted from plants, which will be faster and safer, and more suitable for use under family conditions.

3. Chemical method: There are many formaldehyde scavengers on the market, but these formaldehyde removals, what raw materials, what grades, many of them are inferior raw materials will cause clean pollution, it is recommended that you be careful when choosing.

4. Nano adsorption method: materials such as Ye Guangni and activated carbon are good formaldehyde adsorbents, and there are many tiny pores in their materials, so they can absorb a lot of formaldehyde, and the effect of activated carbon will be a little worse, but it is cheap.

Step 1: Adopt the plant decontamination method. Indoor suitable for planting flower plants are: spider plant (including orchid grass), cactus (cactus), aloe vera, etc., this kind of plant has a certain deodorization effect, but with plant absorption, long time, the effect is not obvious.

Step 2: Diallin formaldehyde scavenger decomposes. After effective ventilation, indoor air pollution has been greatly reduced, and the release of formaldehyde inside furniture is indeed a relatively long process.

Step 3: Open the windows for ventilation. The decoration has just ended, the smell of the new house is serious, and the pollution must be several times, or even dozens of times exceeded, so the initial one to two weeks, what means do not play a big role, the best way is to open the window for a long time to ventilate.

Step 4: Put more Ye Guang mud in the corner of the room, Ye Guang mud is different from the material of activated carbon, which can be decomposed after adsorption, and will not be saturated by adsorption. At present, this method of removing odors is fast.

(1) Open windows to keep the house ventilated and breathable, and bring formaldehyde out of the room through flowing air;

2) You can put some green plants such as pothos and ivy, which can help absorb formaldehyde in the room, but at the same time, every three days, you need to put these plants on the balcony to facilitate them to release toxic and harmful substances;

3) Use Diallin formaldehyde purifier to spray at home with ventilation to achieve the desired effect quickly.

4) You can also use Ye Guangni to treat, just keep it ventilated for a week.

Methods of removing formaldehyde:

1.The most cost-effective and cost-effective, be sure to ventilate more, ventilation is the most important, keep the indoor air smooth.

2.Physical adsorption method: Because the simple ventilation method is slow to remove formaldehyde, the effect is not particularly ideal, so the physical adsorption method can be used as an auxiliary, the best adsorption materials such as Ye Guangni, etc., the dosage can be selected according to the interior decoration situation and area.

3.Plant absorption method: pothos, cactus, spider plant, iron tree and other plants have a trace absorption effect on formaldehyde.

4.Folk soil method: vinegar, grapefruit peel, etc. Because what I want to introduce is an effective formaldehyde removal method, but the formaldehyde removal effect of the folk soil method has not been proven, so I will not introduce much. Be more careful about your health.

Formaldehyde removal method:

Method 1: Open the window ventilation method.

Opening windows for ventilation can promote indoor and outdoor air circulation, so that indoor pollution can be eliminated to the outdoors. This is a necessary step to remove formaldehyde after renovation. The advantage is that the formaldehyde removal efficiency is high, saving money and environmental protection; The disadvantage is that it is difficult to remove formaldehyde in depth, which is greatly affected by the weather temperature, and it is impossible to ensure that the window can be opened at every moment, so it is often necessary to cooperate with other methods to assist in removing formaldehyde.

Method 2: Physical adsorption method.

Natural materials such as Maya blue and activated carbon have porous structures, and these pores happen to be slightly larger than harmful gas molecules such as formaldehyde and toluene. Mayan blue also has a weak electrical property that locks these molecules firmly and prevents them from escaping back into the indoor air. This method can protect the family around the clock, but the disadvantage is that the adsorption capacity of activated carbon is limited and the service life is short; And the ** of Mayan blue is slightly higher.

Method 3: Photocatalyst decomposition method.

Photocatalyst is a catalyst that can decompose harmful organic compounds such as formaldehyde, toluene, and TVOC into harmless gases under the action of light, so as to achieve the purpose of removing formaldehyde. The photocatalyst itself is a harmless substance, and its decomposition products are not harmful, so it is an excellent formaldehyde removal material. Photocatalyst wood essential oil, leather formaldehyde removal care solution and other products not only remove formaldehyde, but also have the effect of maintaining flooring and furniture leather.

The photocatalyst needs to react in the presence of light, because the more light the photocatalyst is used, the better.

Method 4: Plant absorption method.

There are many articles on the Internet that pothos, aloe vera, cactus, spider plant and other plants can absorb formaldehyde, but this claim is unfounded. Experiments have shown that formaldehyde is harmful to plants, formaldehyde will react with plant cells and destroy plant tissues, and these formaldehyde are mistaken for plant absorption. Moreover, the amount of formaldehyde that reacts with plants is also very limited, which is not enough to significantly improve the indoor pollution situation.
