I only learned about the removal of formaldehyde by polymers because my home was going to be renovated this year. There are many products on the market, including the removal of formaldehyde by wrapping photocatalyst, and the removal of formaldehyde by carbon package, which have been understood, but they all have considerable limitations, such as photocatalyst removal of formaldehyde, which needs to be relatively strong in sunlight and sufficient ultraviolet rays to fully react. Like indoors, many places are not exposed to enough sunlight.
After the recommendation of my friend at the testing station, polymer formaldehyde removal is the first polymer material to remove formaldehyde that has begun to come out in recent years. There are many kinds of polymer formaldehyde removal materials on the market, such as Luxiang polymer formaldehyde removal, and Fujita polymer formaldehyde removal. Fujita's advertisements are relatively large, and the official website has been looking for a long time but has not found it, and there is no qualification certificate, which feels a bit deceiving.
Through the introduction of friends, I learned about the formaldehyde removal of Luxiang polymer, the principle of Luxiang polymer formaldehyde removal is through the oxygen yang reaction, using the flow of air, the indoor formaldehyde and harmful substances are decomposed into carbon dioxide and water. After the quality inspection center of the national authoritative organization, the aldehyde removal rate can reach 96%. Therefore, if you want to remove formaldehyde, it is recommended to use polymer to remove formaldehyde.

The formaldehyde scavenger is sprayed on the unfinished wood-based panel, the capture factor penetrates into the board, and then captures the free formaldehyde in the wood-based panel, and then repairs and strengthens it into a network structure, and the last step is polymerization and reduction: all formaldehyde is polymerized and reduced into an irreversible insoluble resin, which solves the problem of formaldehyde release from wood-based panels. Naga polymer polymerization aldehyde removal technology has applied for national patents.

Formaldehyde is emitted slowly, and any chemical formaldehyde removal method can only remove what has been emitted, and it is useless for it to be emitted in the future.

There are two aspects of the principle, the first is chemical decomposition, such as the decomposition of formaldehyde into carbon dioxide and water with chemicals that can react with formaldehyde. The second is adsorption, such as using activated carbon and other objects with pore size, adsorbing formaldehyde into the pore size, and then replacing it regularly.
Share some ways to get rid of formaldehyde.
Ozone method: Through the ozone machine, the odor and harmful substances in the car are eliminated in a short time.
Advantages: Fast removal of odor in the car.
Disadvantages: It is also a source of pollution, the treatment effect is not long-lasting, and the sampling has strong redox and corrodes the materials in the car.
Chemical decomposition method: the principle of formaldehyde in the industrial department, using chlorine dioxide, hypochlorous acid, copper chloride, ammonium chloride for treatment (commonly known as: urea).
Advantages: fast response time, **extremely low.
Disadvantages: The retention time of the treatment effect is very short, and the car produces secondary pollution and peculiar smell.
High-temperature fumigation method: use the physical properties related to temperature and humidity of formaldehyde emission to heat the temperature of the plate and accelerate the release of harmful substances such as formaldehyde.
Advantages: speed up the release of formaldehyde, and the temporary deodorization speed is faster.
Disadvantages: high temperature is easy to cause damage and deformation to the plate, and the superficial formaldehyde of the plate is released to a certain extent.
Formaldehyde scavenger: strong oxidizing agent, such as chlorine dioxide, hypochlorous acid, hydrogen peroxide, etc., decomposes harmful substances in the room and in the car, and quickly reduces harmful substances on the surface of the simple substrate.
Advantages: Reduced release of harmful substances in a short period of time.
Disadvantages: short durability, corrosion to objects.
Activated carbon: Activated carbon is aimed at indoor and in-vehicle air pollution, but only uses the adsorption principle of activated carbon.
Advantages: low cost, non-toxic***.
Disadvantages: passive adsorption, the activated carbon in the wrapped state is only adsorbed on the outer surface but the adsorption saturation is also easy to release, and the carbon bag needs to be replaced continuously for a long time, and long-term use is easy to lead to secondary pollution.
Biodegradation, bioenzymatic degradation method:
Advantages: It is generally used for the degradation of organic matter in domestic sewage, improving water quality, and is inexpensive.
Disadvantages: The microorganisms (Bacillus, Pseudomonas) used in indoor air survive in the nutrient solution and require a certain humidity, which is easy to cause microbial dormancy or death in the indoor environment.
Plant adsorption method:
Advantages: There is a certain ornamentality, and the aromatic smell can moderately mask the sensory discomfort of people.
Disadvantages: Limited adsorption capacity.

First of all, it is certain that formaldehyde removal is credible, but there are tens of millions of ways to remove formaldehyde, people hope that formaldehyde and other harmful gas decoration pollution in the room will be removed from formaldehyde, but it is inevitable to take some detours, we must avoid these three types of formaldehyde mistakes! Today, we will take an in-depth look at the principles of these three major misunderstandings of formaldehyde.
1: Can green plants absorb formaldehyde?
We believe too much that plants can effectively absorb indoor formaldehyde, but we must note that green plants are the same as our human body, and their absorption process is just to apply their own resistance. The use of green planting to remove formaldehyde is only a task imposed on plants by humans, and in the process, the plants themselves are harmed, and many plants are also harmed in environments with high concentrations of formaldehyde, severe or even dead. That's why one can tell if there is formaldehyde in a room by looking at the signs of plants.
Safflower is particularly sensitive. When the formaldehyde concentration is high, the plant damages faster, and the entire leaf is yellowish-brown, wilting until death.
Two: Pineapple peel and grapefruit peel can absorb formaldehyde?
Using part of the peel to absorb formaldehyde is a method that many people like to use nowadays. **TV station financial channel once had a program "Is it real", which talked about the removal of formaldehyde from grapefruit peel and pineapple. Is it true?
During the live broadcast, the guests did the experiments on the spot, and the results surprised many people. The results showed that the formaldehyde content of teak bark in the same closed environment was ten times higher than that of the blank warehouse. The reason is that after the grapefruit peel is put into a closed environment, the temperature rises, and the formaldehyde release also increases (the formaldehyde release will increase with the increase in temperature) This is because the taste of the fruit masks the taste of formaldehyde, so people are reminded not to blindly believe these prescriptions for removing formaldehyde.
Three: Can water, vinegar, and tea really remove formaldehyde?
Because formaldehyde is easily soluble in water, naturally, people will feel that some additional basins at home can be used to absorb formaldehyde, and then use vinegar or tea or soak in water to play is the effect of sterilization, and absorb formaldehyde, formaldehyde in the air will dissolve in water when it encounters water, which is the nature of formaldehyde rights, but the contact area of water and air basin is only the size of a basin when moving, we can imagine, how does formaldehyde absorb water? Compared with activated carbon adsorption, the specific surface area of 1 gram of activated carbon can reach that of a football field in the internal pores, and its effect on indoor formaldehyde adsorption is generally the same. Therefore, putting 100 basins of water in the room is actually not stronger as activated carbon adsorption.
Therefore, the adsorption of formaldehyde using the water and vinegar method is obviously extremely precise.
Therefore, these methods can not only remove formaldehyde, but also increase the indoor formaldehyde content. What causes people to misunderstand? It can be said that these formaldehyde removal methods are a kind of folk formaldehyde removal methods summarized by life experience, which is a truth that has been tested by time and practice.
However, this method is a formaldehyde removal method that has no scientific basis.

There are two principles in addition to formaldehyde, one is chemical decomposition, such as decomposing formaldehyde into carbon dioxide and water with agents that can react with formaldehyde, and the second principle is adsorption, such as using activated carbon and other objects with pore size, adsorbing formaldehyde into the pore size, and then replacing it regularly.
And no matter what air conditioner has, it has an adsorption effect; If you place chemicals that decompose formaldehyde in the exhaust vents of other air conditioners or in the room, you can also adsorb formaldehyde. Haier just has one more device to store formaldehyde, and in the real sense, it is only adsorption, and does not have the detection function. It's just a misleading way about consumption.

There are many ways to remove formaldehyde, such as opening windows with the wind, activated carbon, plants to remove formaldehyde and other methods can reduce the content of indoor formaldehyde to a certain extent.

In addition to formaldehyde, of course, it is credible, and generally there will be a lot of formaldehyde pollution in the decoration of new houses, and formaldehyde can be removed by some methods
1. You can choose to open the window for ventilation, which is a simple method, but correspondingly it is also a method with a very insignificant effect, because this only depends on the volatilization rate of formaldehyde.
2. There is also a physical adsorption method, there is no chemical component pollution, and there is a nano-adsorption aperture in materials such as Ye Guangni, which can effectively decompose harmful gases such as odor formaldehyde and toluene.
3. Water mixed with vinegar can play a role in stabilizing formaldehyde.
4. Huankang nano aldehyde enzyme. It is still very environmentally friendly to use photocatalyst decomposition technology to remove the root cause.
5. Put some tea, grapefruit peel, and fruit, this is the old way, not very well-founded.
-
It is necessary to remove formaldehyde, because formaldehyde is too harmful and has a good reference for removing indoor air pollution:
1.Open the window for ventilation and put the water with vinegar in the ventilated room2In the place where the furniture door is opened, put some activated carbon and leaf wide mud to absorb and decompose.
3.Use special deodorant detergents, which are generally sold in supermarkets.

Credible, formaldehyde is now the primary problem of new house decoration, the current treatment of decoration pollution methods:
1. Air exchange method: air exchange is ventilation, the higher the indoor and outdoor air exchange rate, the better the effect of reducing indoor pollutants.
2. Physical adsorption method: the use of activated carbon and other products to adsorb harmful gases, and at the same time assist ventilation, which can effectively improve the effect of removing pollution. The better ones have leaf wide mud, which is absorbed for a long time, is not saturated, and can also be decomposed.
3. Plant purification method: green plants used to decorate the living environment can also purify indoor air. For example, ivy, iron tree spider plant, aloe vera, etc.
-
The principle of removing formaldehyde is nothing more than to disperse formaldehyde, or use something to adsorb formaldehyde, better to decompose formaldehyde, in fact, there are many ways to remove formaldehyde at home:
1. The high temperature environment in summer can be used to speed up the volatilization rate of formaldehyde. Be sure to open all furniture doors and drawers, open all windows in the room, and have a few fans to speed up the air convection effect.
2. Plants have a strong ability to absorb formaldehyde, such as cactus, spider plant, reed, ivy, iron tree, chrysanthemum, etc.
3. Photocatalysts, such as photophyllin, can directly decompose formaldehyde and other harmful substances.
4. Activated carbon: the use of Yeguang mud material to adsorb polluting gases, effectively decompose internal formaldehyde pollution, and be effective for a long time.

The principle of polymer formaldehyde removal is to decompose formaldehyde and harmful substances in the room through the oxygen-positive reaction and the flow of air into carbon dioxide.
and water. After the quality inspection center of the national authoritative organization, the aldehyde removal rate can reach 96%.
There are other effective methods to remove formaldehyde, which are common as follows:
1.Ventilation and aldehyde removal method. Opening the window for ventilation is a method, because it is really convenient, it only requires us to open the window, and it is completely free.
The principle of this method is mainly to open doors and windows to circulate indoor air and replace it with outdoor air, so as to discharge formaldehyde out of the house and effectively reduce formaldehyde concentration.
2.Super adsorption and aldehyde removal method. Like activated charcoal.
This product has a strong adsorption capacity for formaldehyde and is recognized as an effective formaldehyde removal product. Although activated carbon has a good treatment effect on formaldehyde, its adsorption range is relatively small, so it is generally only suitable for removing aldehydes in small spaces.
3.Air purifier aldehyde removal method. When you want to remove aldehyde, you can buy an air purifier with this function, which has an excellent effect on removing formaldehyde.

Now the principle of removing formaldehyde is basically decomposition, isolation and evacuation.
The way to decompose formaldehyde is the photocatalyst, many companies, shopping malls, families will hire companies to remove formaldehyde, the principle is to use photosynthesis, photocatalyst under the action of ultraviolet light, the electrons on the valence band transition to the conduction band, in the valence band to produce corresponding holes, the generation of superoxide ion radicals, hydroxyl radicals, superoxide hydroxyl radicals with strong oxidation effect, not only formaldehyde, benzene, toluene, xylene, ammonia, TVOC and other toxic and harmful gases, pollutants, odors, Bacteria and other bacteria oxidize and decompose into harmless CO2 and H2O for release.
Isolation is the removal of aldehyde spray, after spraying the article, the release of formaldehyde is isolated from the air to prevent the release of formaldehyde.
Evacuation is to open the window for ventilation, the indoor formaldehyde and various odors are released, and the window ventilation is the most effective way to remove formaldehyde, but it can not go out completely.

Formaldehyde is a harmful other, has an impact on human health, if the room contains this gas, and the content exceeds the standard, it is not lived, formaldehyde can be removed after living in, so what is the principle of removing formaldehyde?
1. Physical masking method: pineapple, grapefruit peel, perfume, air freshener; Physical adsorption: activated carbon, diatom pure, nano mineral crystal, phytoncide, etc.; Physical Blocking Category: Blocking Agent.
2. Chemical method: formaldehyde has reducibility, and it undergoes redox reaction with substances with strong oxidizing properties to oxidize formaldehyde into formic acid, thereby reducing the content of formaldehyde; Nucleophiles are negative ions and neutral molecules with unshared electron pairs as nucleophiles, which react with formaldehyde by sharing electrons or donating electrons, so as to achieve the purpose of removing formaldehyde.
3. Extraction method: extract the corresponding substances from plants, carry out chemical reactions such as oxidation, nucleophilicity, and complexation with formaldehyde to remove formaldehyde, spray microorganisms on the construction surface, and degrade or produce corresponding substances to react with formaldehyde to remove formaldehyde.
The principle of removing formaldehyde is mainly to use air fresheners to temporarily cover the smell of formaldehyde; The corresponding substances are extracted from plants and chemically reacted with formaldehyde such as oxidation, nucleophilia, and complexation to remove formaldehyde.
There is such a long-standing saying, "green plants can completely remove formaldehyde", so after decorating a new house, many people will take the initiative to buy a few pots of green plants, such as monstera, spider plant, pothos, aloe vera, cactus, etc., and put them in the room. So, can these green plants remove formaldehyde? >>>More
It is completely possible to buy products on Tmall Mutong *** yourself. This also saves a lot of money.
The decoration of the new home, the joy of housewarming, and the smooth chapter. But many friends have to consider formaldehyde as a "health killer" before moving into a new home, after all, there are too many bloody examples caused by indoor formaldehyde pollution. >>>More

1. Ventilation method.
The ventilation method does not have to be explained too much, that is, through the flow of air, the harmful gases are discharged to the outdoors, which is a simple and effective method, the disadvantage is that the formaldehyde release cycle is long, generally three to fifteen years, after the decoration of the new house idle for more than three years is obviously unrealistic, the method of ventilation seems too ideal, unrealistic. >>>More
