Which method is best to remove formaldehyde? What are the best ways to remove formaldehyde?

Photocatalyst formaldehyde removal is very good and best, Shanghai Ice Insect Phototechnology Catalyst, Shanghai Ice Insect environmental protection effect is very good, if their governance team governs, there is a five-year warranty, very responsible.

Ventilation method: open windows for ventilation. This is a method that can effectively remove formaldehyde, but when the formaldehyde concentration is high (under the GB T18883-2002 standard, formaldehyde exceeds, it cannot play a role in removing formaldehyde.

In addition, during the ventilation process, please pay attention to increase the air source (such as electric fans, etc.).

1. Bamboo charcoal takes "drugs" and does not lock "drugs".

The reason why bamboo charcoal and activated carbon can have super adsorption capacity is that there are many microporous structures with a size of microns, which provide a hiding place for water molecules, fine dust, formaldehyde molecules in the air, etc., but these pores cannot prevent the volatilization of the substances adsorbed, which forms the so-called "secondary pollution".

The authoritative academic journal "Forest Products Chemistry and Industry" has published an article on the adsorption performance of bamboo charcoal on formaldehyde, the article recorded an experiment, the bamboo charcoal is placed in nearly saturated formaldehyde vapor, the adsorption capacity of formaldehyde is 68 mg per gram of bamboo charcoal, and the bamboo charcoal that absorbs formaldehyde is placed in a room without formaldehyde, and the formaldehyde content in the bamboo charcoal drops to 34 mg within 3 hours, and drops to mg after one day. The experimental results prove that the adsorption capacity of bamboo charcoal in the environment full of formaldehyde is indeed amazing, but it does not have any ability to lock the adsorbed formaldehyde, once the formaldehyde content in the environment is reduced, the formaldehyde that has been adsorbed will immediately volatilize and become a secondary pollution source.

Second, the effect of air purifiers in removing formaldehyde is questionable.

The principle of formaldehyde removal in air purifier is basically similar to that of bamboo charcoal, and the fan is used to pump the indoor air through the filter, which intercepts various dust particles and formaldehyde in the air. However, the purification effect of the filter air purifier has been questioned by research institutions and many **, formaldehyde molecules are tens of thousands of particles, and the removal effect can be imagined. Both the national quality supervision department and the consumer association have pointed out that the "formaldehyde removal rate" proposed by many big brands of air purifiers is false propaganda.

In addition, the filter of the air purifier is not replaced in time, and there is also the problem of secondary pollution.

3. Negative ions are promoters in the decomposition of formaldehyde.

In chemical reactions, negative ions are an important active substance, which can promote chemical reactions between many substances that are difficult to react with each other to produce new substances. The use of negative ions to remove formaldehyde is to use the chemical promotion of negative ions to promote the separation of formaldehyde oxygen chains in formaldehyde molecules, so that they can be decomposed into water and carbon dioxide, which completely solves the secondary pollution in the process of formaldehyde purification, and can be used for a long time, effectively solving the problem of formaldehyde pollution for a long time. Small particle size anion has high activity and can migrate to all corners of the room by itself to achieve maximum decomposition of formaldehyde, so that there is no dead angle in the whole process.

In the process of air purification, once there is secondary pollution, the adsorbed large dose of formaldehyde is emitted in a short time, which is more harmful to the human body. There are various ways to remove formaldehyde, and its effect and whether there are no worries have become an important criterion for choosing a formaldehyde removal method.

Fresh air system. It is to use the function of ventilation to continuously discharge the indoor formaldehyde dirty gas outdoor, and at the same time send the outdoor fresh air purified by the machine to the room to ensure the freshness and cleanliness of the indoor air.

1. Ventilation to remove formaldehyde

Ventilation is currently the most effective way of air purification, which can use air circulation to bring out harmful substances such as formaldehyde in the room, and can also use large industrial fans to increase the air volume to make the indoor and outdoor air flow more smoothly, so as to purify the indoor air, take away the dirty air, and reduce pollution.

2. Green plants and activated carbon

Green plants and activated carbon are well-known and commonly used ways to remove formaldehyde, for green plants and activated carbon, it is a well-known indoor air purification method, but the effect of this method is weak, and it cannot quickly remove formaldehyde.

3. Fresh air system

Fresh air system is now a more high-tech way to remove formaldehyde, to the summer need to turn on the air conditioning, winter needs to turn on the heating, if the indoor air is not circulated, then it will produce a lot of harmful substances, want to achieve air exchange, you need to install a fresh air system to keep the air fresh, the efficiency is still good.

4. Formaldehyde removal company

For the new house in addition to formaldehyde, now the use rate of formaldehyde companies is still very high, if your home formaldehyde exceeds the standard seriously, it is best to hire a good formaldehyde removal company for testing, according to the indoor situation for formaldehyde treatment. The way of application is still relatively scientific, using the reaction of titanium dioxide and formaldehyde to decompose into harmless carbon dioxide and water, so as to remove formaldehyde.

1. VentilationIf there is a most effective way to remove formaldehyde, then ventilation is definitely in the first place. Because formaldehyde is slowly volatilized, if the indoor formaldehyde concentration reaches a certain level, formaldehyde volatilization will also slow down because it is saturated. Open the window, keep the indoor air and outdoor air circulation, that is, air exchange, and take formaldehyde directly out of the outside, then formaldehyde will continue to volatilize and be continuously taken out of the outdoors.

2. Activated carbon packThe principle of activated carbon air purification: relying on the developed pore structure and surface area of the carbon itself, it can be in contact with the surrounding air to a large extent, and passively adsorb some pollutants into its own pores, so the larger the surface of the activated carbon, the more developed the pore structure, the stronger the adsorption capacity.

3. PhotocatalystPhotocatalysts are another common tool for removing aldehydes; Using the principle of redox, formaldehyde and other harmful substances are decomposed into carbon dioxide, water and other harmless substances. The advantage is that it is easy to operate and effective, but it should be noted that it only works in an environment with light or ultraviolet light

Formaldehyde removal should be the most concerned topic for every new family, and there are so many ways to search for formaldehyde removal methods on the Internet. Countless "many people believe in the misunderstanding of formaldehyde removal", "99% of people say that the effective method of formaldehyde removal", many people are confused. The following will give you an analysis of several basic methods and advantages and disadvantages of formaldehyde treatment.

1. Wise Stone.

It can actively adsorb indoor free formaldehyde, the process will not be affected by any external factors such as temperature, humidity, light, etc., the adsorption rate of formaldehyde is also dozens of times that of ordinary adsorption materials, in addition to the unique decomposition function, the adsorbed formaldehyde can be decomposed into harmless carbon dioxide and water, and then discharged, so that its internal pores have been in an unsaturated state, and the aldehyde removal rate can reach more than 90%. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

2. Open windows for ventilation.

This is nature's gift to us, and it is the most economical way to remove aldehyde, as long as you open the window, fresh air will enter the room, and formaldehyde will be purified by dilution

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.

Fourth, high temperature.

The release rate of formaldehyde mainly depends on two factors, one is temperature, the other is humidity, so we can use this characteristic of formaldehyde, use heaters, humidifiers, etc. to keep the room in a state of high temperature and high humidity, and then we can cooperate with ventilation or adsorption materials to absorb the formaldehyde that has been released at home, this method is mainly to treat the latent formaldehyde in the home, and the effect is very good.

5. Photocatalysts.

At present, most of the photocatalysts that are often mentioned are titanium dioxide, which can decompose formaldehyde into carbon dioxide and water through ultraviolet irradiation, but it needs to be involved in light and ultraviolet rays when working, and there are certain restrictions in removing formaldehyde.

Most of us are office workers, and time is very limited, so if you want to remove formaldehyde from the air as soon as possible, it is best to do it in a variety of ways at the same time.

With the improvement of modern social and economic level, people's pursuit of home life is not limited to "being able to live", but paying more and more attention to environmental protection, and more of the pursuit of "being able to live with peace of mind". However, indoor pollution has always been an unsolved problem and is even getting worse. The core problem is formaldehyde.

Many people are talking about aldehyde discoloration, not to mention other decoration pollution.

Therefore, we must use the right method when removing formaldehyde, and quickly follow the following 4 tips for removing formaldehyde that are super effective.

Tip 1: Electric fans to enhance ventilation.

Ventilation is something that must be done after the installation of the new house, although it cannot completely rely on ventilation to remove formaldehyde, but ventilation is the foundation and must be done. In addition, in order to increase the ventilation effect, we can open the furniture door, and at the same time formulate an electric fan to accelerate the indoor air circulation, which is also helpful to increase the ventilation effect.

Tip 2: Break down furniture effectively.

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.

Tip 3: Natural spray spraying.

The algae spray needle is a natural aldehyde remover used in furniture, mainly natural mineral ingredients, its own safety and non-toxic, the pH value is also neutral, there is no harm to the human body and furniture, after spraying the surface of the furniture, it can penetrate the inside of the furniture board, accelerate the decomposition of the pollution in the board, and can purify formaldehyde from the source, and remove furniture pollution and odor.

Tip 4: Green plants assist in purification.

Although the effect of green plants on removing formaldehyde is not particularly obvious, green plants such as spider plant, pothos, tiger piran, yew and other green plants still have a certain effect of purifying the air, which can make the air quality in the room fresher.

It is also possible to speed up the progress of formaldehyde treatment in new houses and shorten the waiting time for occupancy by taking some treatment measures (the cost is definitely lower than the rent) in their own way.

1. The most important thing is ventilation. Answer: The main decoration is just at the end of May last year, coordinates Hangzhou, the weather is relatively fine, natural ventilation is the most economical and effective way, no cost, especially in the warmer (hot) season, formaldehyde is volatile (19), at this time the effect of natural ventilation is very good, note, continuous window ventilation will be better than the effect of stuffy method.

2. You can use a floor fan to assist indoor air circulation, and the blowing effect on the open furniture is better, and then it can also be used at home without waste.

3. Activated carbon. Activated carbon is a class of materials, and its principle is physical adsorption of formaldehyde, and it should be noted that it must be coordinated with ventilation, because it cannot actively capture impurities such as formaldehyde, and air must flow through its pores in order to passively adsorb impurities and formaldehyde. **It is also relatively cheap, and it can also be put in the refrigerator and shoe cabinet to remove odors in the future.

4. Photophyllin formaldehyde scavenger, which is sprayed directly on the pollution source, can accelerate the release of formaldehyde inside, and at the same time can decompose formaldehyde and other decoration pollution. Compared with other chemical sprays, it does not require light and ultraviolet rays, is not a blocking agent, has no secondary pollution, and is recommended for families with babies and pregnant women.

Go to see some evaluations, you can find that the products in addition to formaldehyde have a certain effect, but to compare the best and the effect, that is, the cost performance, make a trade-off, some people feel that the materials are solid wood, metal-based, or can wait for a year and a half before moving in, that may indeed be the same light and ventilation, some of the check-in time is more tight, or they are more uneasy, there are pregnant women and children at home, and those who are sensitive to it, it is also worth using some.

Formaldehyde is very harmful to the human body, and the newly renovated house contains a large amount of formaldehyde and other harmful substances, so the newly renovated house cannot be moved in immediately, and it will be safe after we need to treat it.

Activated carbon adsorption method, this formaldehyde treatment method is very effective, and activated carbon is a more practical and inexpensive item. Activated carbon removes formaldehyde through physical adsorption, which will not cause secondary pollution to the environment, and activated carbon also has the effect of deodorization, which can reduce indoor odor.

When the photocatalyst is also a photocatalyst, when absorbing ultraviolet and visible light, the pollutants in the air are adsorbed to the surface of the photocatalyst and will be oxidized into carbon dioxide and water, so as to achieve the purpose of purifying the air. It is not only effective for formaldehyde, but also for some other volatile toxic and harmful gases.

The ventilation method is a cost-effective method of removing formaldehyde, which is particularly effective in the face of high indoor formaldehyde concentrations, and the effect is also very obvious for newly renovated houses. For the newly renovated house, it is necessary to open more windows and ventilate more, so as to ensure that the indoor air can circulate well, which can reduce the content of harmful substances in the indoor air. If the indoor air is not circulated, it is easy to increase the formaldehyde content in the room, which will cause great harm to the human body.

If the indoor pollution degree of Cheng Hengqing is below medium and low, then you can take plants to remove formaldehyde. Green plants can not only beautify the decorative environment, but also can strongly remove formaldehyde.
