Which products have a good effect on formaldehyde in new houses?

In addition to activated carbon packets, there are also photocatalyst formaldehyde cleaners and air purifiers with formaldehyde removal functions.

Formaldehyde can be removed by physical means.

Indoor ventilation is the best way to do it. Fastest.

You can add a charcoal bag and adsorb it with activated carbon.

Chemical methods are also possible, but the product must be environmentally friendly after the reaction.

For example, the addition of copper hydroxide can ensure that the product is environmentally friendly.

HCO 2Cu(OH)2 HCOOH Cu2O 2H2O You can also put potassium permanganate in the container, and add some dilute sulfuric acid, pay attention, do not spill it on the cabinet, it should fade. Formaldehyde reacts with acidic potassium permanganate. The reaction produces potassium sulfate, manganese sulfate, water, and carbon dioxide.

The chemical equation for the reaction is:

5hcho+4kmno4+6h2so4==2k2so4+4mnso4+11h2o+5co2↑

Note: Formaldehyde oxidation to produce carbon dioxide is because formaldehyde is first oxidized to form formic acid HCOOH, and formic acid also contains an aldehyde group, which continues to be oxidized to form carbonic acid. Carbonic acid is unstable and decomposes to form carbon dioxide and water.

Formaldehyde in the treatment of new houses. What everyone uses is to buy some carbon to remove formaldehyde. Raise some plants, such as tiger piran. Pothos. Or maybe there are some. Fruit.

The flower shop has flowers that specialize in absorbing formaldehyde, which are very cheap and good-looking.

In fact, opening windows for ventilation is the best, and I think everything else is.

I compared a lot of them, and I couldn't get started. Later, after being introduced by acquaintances, I feel pretty good, and the aldehyde removal effect is first-class.

New house decoration to formaldehyde priority or open windows for ventilation, while configuring a good air purifier is also essential, Stevo air purifier is equipped with dual-core power system and nanotechnology, in the purification of the air, in sterilization, odor, purification at the same time can also quickly decompose formaldehyde, formaldehyde CADR value of 550mg m, formaldehyde removal rate of up to 98%, removal of harmful substances such as toluene, etc., combined with 6 filter structure, can effectively filter a variety of harmful substances in the air.

It can only be said that part of it is useful, because there are many companies in addition to formaldehyde, and the technology is uneven, the release life of formaldehyde is still very long, and it is easy to exceed the formaldehyde standard when the ventilation is not smooth, so how should we deal with formaldehyde, recommend several methods that you can operate yourself.

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 does not have to worry about the influence 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. Plants.

Choose plants that can adsorb formaldehyde, pothos, aloe vera, spider plant and other plants can adsorb a certain amount of formaldehyde pollution, and can indeed remove formaldehyde. Placing some greenery in your new home can also help to beautify the room and freshen the air. However, the adsorption capacity of plants is relatively limited, and if the formaldehyde concentration is too high, the plants will wilt and die.

3. 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.

4. Formaldehyde remover.

Formaldehyde scavenger is the use of chemical or biological principles, formaldehyde decomposition into harmless carbon dioxide and water or other harmless substances, so as to achieve the purpose of purifying formaldehyde, but there are many manufacturers, the quality is also uneven, you must keep your eyes open when buying, otherwise it is easy to cause the introduction of other harmful substances.

Fifth, the fresh air system.

The principle of the fresh air system is ventilation, the outdoor fresh air is filtered and transported to the room, and then the harmful substances containing formaldehyde are discharged outside to achieve the effect of removing formaldehyde.

The newly renovated house has a lot of indoor formaldehyde content, so it is recommended to use a variety of methods to use it together, which is practical and healthy, and control formaldehyde within a safe range as soon as possible.

In fact, formaldehyde scavengers can only temporarily seal the source of pollution and prevent formaldehyde volatilization in a short time, and cannot completely remove formaldehyde pollution at all. Because formaldehyde pollution is continuous, usually lasts for 10 to 15 years, if the product is called disposable ** or completely **, unless the formaldehyde itself has volatilized, it is basically impossible.

I don't think it has any effect, he will show you what to say with one of his own testing tools, and show you how much the value is now, this value is normal, in fact, it is all high-tech things, he wants to remove these formaldehyde, he must put other chemicals to take these things, but you have some more chemical composition of other things in your house, and you don't have the tools to measure these things, and you don't know what effect these things have on the human body.

1. Take activated carbon adsorption and then use the sun to dry it.

2. Take the tea leaves, take the coffee beans to suck the taste.

3. What green plants to buy, Tiger Piran, Aloe Vera, Cactus, these Buy a little more 4, Open the windows for ventilation, but open the weather, don't open it on rainy days.

5. Open the wardrobe, the desk, and the drawers.

If you have enough money, you can find someone from a special company to do it, or buy some Huankang nano aldehyde enzyme to treat it.

Formaldehyde has a volatilization time of up to 3-15 years, so it cannot be removed. Formaldehyde can be removed by:

Method 1: Ventilation method to remove formaldehyde hazards.

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.

Method 2: Activated carbon adsorption method to remove formaldehyde hazards.

Activated charcoal is an internationally recognized drug addict, activated charcoal masks, gas masks are all used activated charcoal. It is to use the physical action of activated carbon to deodorize and detoxify.

Method 3: Plant deodorization method to remove formaldehyde hazards.

Plant decontamination can be selected for medium and low pollution: general indoor environmental pollution in the environment with 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. In general, in a room of about 10 square meters, it is more appropriate to put two pots of plants with a height of meters. Generally, we can place spider plants, tiger pill orchids, and aloe vera indoors to adsorb harmful objects.

1. Place green plants. It works 24 hours a day, but it has little effect.

2. Open windows for ventilation. The effect is good, and it is generally suitable for daytime.

3. Place the activated carbon packet. Suitable for small spaces such as drawers and wardrobes. After the activated carbon is saturated, it can be placed in the sun and reused.

4. Ozone sterilizer. It is suitable for regular or irregular use, which can not only remove formaldehyde, but also sterilize and disinfect.

5. Spray photocatalyst spray. If there is light, it can be decomposed.

6. Air purifier. It is suitable for use at any time, but it does not eliminate pollution with high CO2 concentrations.

7. Wall-mounted fresh fan.

One of the methods for removing formaldehyde in the new house: under the irradiation of light, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis, produce free hydroxide groups and reactive oxygen species with strong oxidation ability, have strong photoredox function, can oxidize and decompose various organic compounds and some inorganic substances, can destroy the cell membrane of bacteria and solidify the protein of the virus, can kill bacteria and decompose organic pollutants, and decompose organic pollutants into non-polluting water (H2O), carbon dioxide (CO2) and other harmless substances. Therefore, it has strong sterilization, deodorization, mildew-proof, anti-fouling and self-cleaning, and air purification functions.

The second method of formaldehyde removal in the new house: air purification spray plant-derived biological agents use biotechnology to refine and extract its active ingredients sesquiterpene polyesters and alcohol compounds from plants such as Italian black poplar, mountain black locust, and neem, and prepare plant-derived compound purification liquid with beneficial formulas, with significant and long-lasting sterilization effect, tested by the Hong Kong Polytechnic University and other departments, for Salmonella, Shigella, pathogenic Escherichia coli, Vibrio cholerae, Staphylococcus aureus, Legionella and SARS coronavirus, **susceptible virus, Avian influenza viruses and other common bacteria, fungi and viruses are killed within 60 minutes. And effectively decompose formaldehyde, benzene, TVOC and other toxic gases.

Instant decomposition, no secondary pollution.

The third method of removing formaldehyde in the new house: the ventilation method does not need 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, and it is obviously unrealistic to idle the new house for more than three years after decoration. Ventilation alone is not enough.

When your new house is well decorated, of course you are very happy, but the smell of the new house decoration is very strong, that is, a lot of formaldehyde makes people very unhappy and unhappy, right.

First of all, you should choose a good season, autumn and summer are the best times to decorate a house, and many families will choose summer to decorate their newly bought house. When it comes to the renovated new house, we can't move in immediately, no matter how good the decoration materials are, we still need to remove formaldehyde.

There are really many ways to remove formaldehyde, such as window ventilation method, activated carbon method, water adsorption method, green plant method, boiling water boiling white vinegar method, and so on.

But the most effective, the one I recommend to you, you just use it, you know, the effect is first-class.

The newly renovated house, the interior will contain a lot of formaldehyde and other harmful substances, for the sake of health, it is best not to live immediately, is there any way to remove formaldehyde in the new house? Here are some ways to remove formaldehyde from new houses, to share with you.

1.Ventilation and aldehyde removal is a gift from nature, as long as the weather allows us to unscrupulously open the window to remove aldehyde, through the dilution method to control formaldehyde within a safe range, but the release of formaldehyde is longer, the use of ventilation to remove aldehyde requires long-term persistence, and other methods need to be taken to reduce formaldehyde concentration when ventilation is not smooth.

2.Plants can remove formaldehyde, although formaldehyde can be removed, but the amount of formaldehyde it absorbs is very limited, and when the indoor concentration is high, if the plant alone relies on formaldehyde adsorption, the amount is very large.

3.Activated carbon has the function of adsorbing formaldehyde and other harmful substances, but activated carbon does not have the function of decomposition, so the adsorption capacity is limited, easy to saturate, and needs to be replaced frequently, otherwise it will become a new pollution source to emit harmful substances to the outside, resulting in indoor secondary pollution.

4.The fresh air system is to purify the outdoor air through the fresh air fan, and then pour the fresh air into the room, but because of its cumbersome installation, it must be completed before the decoration, and the first is high, so under normal circumstances, the fresh air system is only suitable for large industrial enterprises or large office areas, as well as families with high budgets.

5.Photocatalyst is also called photocatalyst, its representative substance is titanium dioxide, which can effectively catalyze the decomposition of harmful substances in the air, such as formaldehyde, toluene, TVOC, etc., which can be degraded into carbon dioxide and water that are harmless to the human body.

It will be a little difficult to use a single method when removing aldehydes, but it is recommended to use a combination of them, which will have a better effect and make aldehyde removal smoother!

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.
