It is too difficult to remove formaldehyde, what are the misunderstandings of removing formaldehyde

First of all, it is clear to everyone that formaldehyde is not good for plants. This chemical can also harm plant cells. Of course, plants such as pothos are more tolerant to formaldehyde and even detoxify

However, it should be noted that this is only a defense response of the plant, and the treatment of formaldehyde is only a last resort. In addition, experiments have shown that plants can only remove a small amount of formaldehyde around the leaves. In fact, plant formaldehyde removal is not effective in removing formaldehyde.

There are too many types of formaldehyde removers on the market, some of which remove formaldehyde physically, and some are called chemical formaldehyde removal. In fact, formaldehyde scavengers can only inhibit formaldehyde for a short time and prevent formaldehyde volatilization in a short time, and it is impossible to completely eliminate formaldehyde pollution. Because formaldehyde release is a continuous, gradual slowdown process, don't expect immediate removal.

Therefore, the formaldehyde remover is completely a pit, so don't step on it.

Vinegar absorbs formaldehyde. Vinegar does absorb some formaldehyde, but in fact it is not vinegar but water. Formaldehyde is chemically soluble in water, actually absorbs the same amount of water, and the effect of absorption or removal is similar.

The difference is that acetic acid will also volatilize into the air, and the vinegar will taste better than the formaldehyde, so you may think that formaldehyde has been removed.

The results of the experiment showed that in the same sealed warehouse, we found that the formaldehyde content of the laboratory where the peel was placed was several times higher than that of the blank warehouse. Because the temperature in the laboratory becomes higher after the peel is placed, the amount of formaldehyde released is greatly increased. Grapefruit peel and pineapple will not only not reduce formaldehyde, but also stimulate the production of formaldehyde in the air, which is really a trap!

There are many products that claim to adsorb formaldehyde, but the effect is not very good, and the best way is ventilation.

Vinegar can indeed absorb some formaldehyde in addition to formaldehyde, but in fact, it is not vinegar that plays a major role, but water. Because formaldehyde has extremely high hydrophilicity and is easily soluble in water, it is said that the absorption or removal effect of the same amount of water is almost the same. The difference is that acetic acid will also volatilize into the air, while vinegar odor can mask the smell of formaldehyde to a certain extent.

It does not remove formaldehyde.

Most air fresheners on the market do not have the function of removing formaldehyde, but they use formaldehyde removal as a selling point, which is fraudulent.

Experiments have shown that plants can only remove a small amount of formaldehyde around the leaves. In fact, plant formaldehyde removal is not effective in removing formaldehyde.

Plants can only alleviate formaldehyde, but cannot completely remove formaldehyde, and vinegar cannot remove formaldehyde.

There are many people who think that vinegar smoking is okay, but I think that in order to reduce these problems, it is really important to have a good product in the early stage.

Plants can only alleviate formaldehyde, aromatherapy can only mask the smell of formaldehyde, and it is best to keep the room ventilated.

Smoked vinegar, many people think that smoked vinegar can remove formaldehyde, but in fact, the important thing is to ventilate, put some plants and activated carbon.

In addition to formaldehyde, try to avoid the misunderstanding:

1. Use black tea, pineapple, orange peel, and air freshener to remove the taste. This method is the most important, because it has no effect at all, and basically masks the smell of harmful gases, but makes you let your guard down. Don't kid yourself.

2. Some people say that potted water at home can absorb formaldehyde, which is groundless, and some people say that plants can absorb formaldehyde. Plants can adsorb a little formaldehyde, but it is so small that it is completely negligible.

3. White vinegar is a folk method, which has no effect at all, please use ozone with caution, it is harmful to the human body. There are also some sprays with plant extracts, please keep your eyes peeled and use with caution!

There are many ways to remove formaldehyde, but it is difficult to meet the requirements with only one method, and the commonly used ones are Mien stone, photocatalyst, activated carbon, formaldehyde scavenger It is recommended that you use the following methods to remove formaldehyde:

1. Open windows as much as possible for ventilation.

2. Put some rice stone in the cabinet, drawer and other places with a big smell, and use its nano-level pores to adsorb harmful gases.

3. With some photocatalyst sprays, choosing a good product is the key, and some products will have secondary pollution.

4. If you have the conditions, buy an air purifier, but it is generally quite expensive, and the good ones are tens of thousands of yuan.

If the smell at home is big, then use the above four points, if the smell at home is not big, then open the window to ventilate, and then buy some solid packets of Mien stone and put them at home.

Some time ago, when my friend moved into a new house, he invited everyone to dinner. During the banquet, I also heard people mention that putting a basin of water in the new house can remove formaldehyde. Everyone at the table argued, some people said that there is no way to remove formaldehyde with water, and some people said that water is quite effective.

Later, the people at the table did not argue with a result, and the friend put water in the room with a skeptical attitude. Every day after work, I would go to the new house to change a basin of clean water, and this situation lasted for a week.

Later, in a casual conversation, I learned that he had done this, so I asked him what the result was. He especially regretted it, and concentrated on doing it for a week, he did the test with the test strip used to test formaldehyde, and found that the formaldehyde reaction of the new house was still very heavy. This week was in vain, and the smell in the new house was still very strong, so I found another way to remove formaldehyde.

Now that my friend has moved into a new house, he summed up with me his method of removing formaldehyde.

The first,Open all the windows in your new house to allow better air circulationExcept for when the weather is bad and he will close the windows on rainy days, basically the windows of the new house have been open for ventilation in the past few months.

Second,Then my friend went and bought a lot of activated charcoal packets, put all corners of the new house. As we all know, activated carbon is also a very good way to remove formaldehyde, but the carbon package used should be replaced regularly. My friend used it for 3 months to replace it, that is, after he first placed it, he placed new carbon packets in all corners of the room.

Third,The greenery at my friend's house was also set up before moving inBecause green plants absorb formaldehyde and other harmful substances in the air through breathing. Common green plants include pothos, ivy, aloe vera, etc.

Fourth, the air purifier is also placed at home after moving in. It should be reminded that the filter element of the air purifier should be replaced regularly. These are the methods that my friend summarized for me to remove formaldehyde, I hope it can help you.

Formaldehyde-free products do not exist, and the formaldehyde content is within the safety standards, which will not cause harm to the human body, so there is no need to pursue zero formaldehyde excessively. But now the method of removing formaldehyde can be described as full of tricks, some we have heard people say, and some are advertised, and unconsciously we have entered the misunderstanding of removing formaldehyde. Next, I will introduce to you a brief analysis of the four misunderstandings in addition to formaldehyde, and a brief analysis of the four major misunderstandings in addition to formaldehyde.

1. Formaldehyde removal misunderstanding - plants completely adsorb formaldehyde?

Plants' ability to breathe is quite limited, and they are usually in the microgram range. If the formaldehyde in the room exceeds the standard, thousands of potted plants need to be placed, and continuous light can have a certain effect.

Second, in addition to formaldehyde misunderstanding - no formaldehyde if it is tasteless?

Just because there's no smell in the room doesn't mean there's no formaldehyde. When formaldehyde exceeds the standard by 2-3 times, there is no obvious odor, and it may also be covered by other odors, and it can stay indoors for up to 3-15 years.

3. Formaldehyde removal misunderstanding - can pineapple remove aldehyde?

The aroma of pineapple can cover the smell, but it can not decompose harmful substances, it contains a large amount of water, which plays a role in humidification after volatilization, but volatilizes formaldehyde after drying.

Fourth, the misunderstanding of removing formaldehyde - can fumigation vinegar remove formaldehyde?

Some people believe that fumigated vinegar can remove formaldehyde. Vinegar is an acidic substance, which has a weak effect of neutralizing ammonia in the air, but it will not react with other harmful components such as formaldehyde.

If the interior is newly renovated, it will produce a lot of formaldehyde, not only the board, but also a variety of fabric products will release a lot of formaldehyde, benzene, TVOC and other pollutants, these old pollutants are very harmful, will have a bad impact on the body. Therefore, it is necessary to remove formaldehyde after the renovation of a new house.

The motivation for us to remove aldehydes must be because formaldehyde is extremely harmful. Because formaldehyde can cause various respiratory diseases, it can also lead to infertility, fetal malformations, and even leukemia, and more serious can be fatal. As early as 2004, the World Health Organization has listed formaldehyde as a first-class carcinogen, which shows how toxic it is!

In fact, with the increasing development of the economy, many of the building materials and furniture we use are with formaldehyde, even if it is an environmentally friendly material, it is not formaldehyde-free, but the content is low, and the formaldehyde concentration is not above the standard, there is nothing, even if it is exceeded, as long as we control it within the range of the standard, it has no impact on the human body, but the volatility of formaldehyde is very strong, and the volatilization cycle is quite long, up to 3-15 years, which leads to the high probability of formaldehyde in our home will repeatedly exceed the standard.

Formaldehyde indoors, especially in new houses, is intricate, man-made panels, decorative materials, building materials, furniture, wall paints, coatings are a large number of adhesives, some textiles are the main formaldehyde, even children's toys also contain a lot of formaldehyde, even if your home uses environmentally friendly materials, when they are volatilized together and superimposed formaldehyde will still exceed the standard, and will repeatedly exceed the standard.

After the renovation of the new house, in order to prevent the family from being harmed, it is still very important to remove formaldehyde.

Formaldehyde is harmful and takes a long time, which is the reason for dealing with formaldehyde, which can keep ventilation.

1. Ventilation method, every day a brother and a town to ventilate at a time point, ventilation is conducive to indoor air circulation, formaldehyde is released.

2. Place some activated carbon bags in the cabinet and leaf wide mud materials to absorb the formaldehyde smell released in the cabinet for a long time.

3. The better ones are the decomposition and removal of plant liquid and the extraction of plants.

5. Many spider plants and aloe vera are chosen to be placed at home, on the cabinet in the bedroom, waiting to grow up.

6. Purifiers and formaldehyde air conditioners are not very effective, because these individuals feel that they are almost the same as ventilation.

7. Salt water wiping household envy coarse tools, grapefruit peel and the like are relatively old generation methods, I don't know if it works, scientifically speaking, it is not possible.

8. Comprehensive treatment is desirable to give yourself a healthy environment.

Formaldehyde is an extremely volatile gas that can stay indoors for up to 3-15 years. Therefore, if there is no smell in the room for a short time, it does not mean that formaldehyde is eliminated. Generally speaking, when the formaldehyde content exceeds the standard by 2-3 times, people cannot smell obvious odors, or some other odors in life can easily cover it up.

Common mistake: ventilate every day.

Formaldehyde is raging, and most people will choose to dry it for as little as a month or as much as a year after decoration. However, we must know that the windows of the general family room will be designed at a position of more than one meter above the ground, and the density of formaldehyde is higher than that of air, which is easy to precipitate, and it is still difficult to remove formaldehyde even if the window is opened for ventilation. In addition, most harmful substances are released slowly, up to 3-15 years, and it is by no means a few months of ventilation that can solve the problem.

In fact, the so-called environmentally friendly paint is not that there is no formaldehyde, but that the content of harmful substances such as formaldehyde is relatively small. The use of eco-friendly building materials can help reduce harmful indoor gases, but even if all eco-friendly building materials are used, the air quality will exceed the standard. In addition, factors such as the design of decoration, the structure of the room, the ventilation condition, and the superposition effect of harmful gases still cannot guarantee that the indoor air quality can meet the standard after the decoration of the room.

Environmental protection mistakes: green plants have a large effect, fresh oxygen and beautification.

In addition to formaldehyde, many people hope that spider plants, aloe vera and other plants will adsorb. In fact, plants have a rather limited ability to breathe, usually in micrograms (parts per million) formaldehyde levels. If the formaldehyde in the room exceeds the standard, thousands of potted plants need to be placed and continuous light can have a certain effect.

Life error: to report bamboo charcoal, activated carbon.

Many people think of using bamboo charcoal and activated carbon to adsorb formaldehyde, and there are many purifiers that use the principle of activated carbon, and the mechanism is to use activated carbon to adsorb formaldehyde. But this method cannot break down formaldehyde and can only capture it temporarily. When the room temperature rises and the adsorption is saturated, formaldehyde will be released again, forming secondary pollution.

If you want to effectively detect and control indoor formaldehyde, you must choose a professional environmental protection company, otherwise it will not only be difficult to meet the standard, but it is likely to cause secondary pollution! Shenyang University of Technology Space Environment Design Institute has a business license issued by the Industrial and Commercial Bureau, and is a company recognized by law. Our hospital adopts a comprehensive treatment method to treat indoor air pollutants in a targeted manner.

The treatment steps are high-temperature fumigation - biological enzyme dissolution - air purification.

After detecting formaldehyde exceeding the standard, it enters the stage of removing formaldehyde, and people often have some misunderstandings about removing formaldehyde

1: Ventilation method

Ventilation can dilute the free formaldehyde concentration in the air of the new house, but the hidden formaldehyde content in the decoration building materials is shocking. Scientific studies have shown that over a period of more than three years, formaldehyde emissions have been relatively high in panels, furniture and wallpaper adhesives. Long-term ventilation can be affected by haze, cloudy and rainy weather.

Therefore, the method of dispersing odors is not suitable for rapid formaldehyde removal in new homes.

2: Override method

Many people think that the taste is gone, and the contaminants will also be eliminated. So, try the method with grapefruit peel deodorization methods and air fresheners. In fact, science has confirmed that grapefruit peels contain a lot of moisture, which can increase the humidity in the air, accelerate the evaporation of pollutants, which will increase pollution in a short time, and air fresheners contain a large amount of the aromatic agent - benzene.

Improper selection can easily lead to excessive benzene.

3: Activated carbon adsorption method

Activated carbon can temporarily adsorb pollutants through its physical adsorption capacity, but it is highly saturated. Saturated activated carbon does not have adsorption capacity, and incorrect treatment will cause indoor formaldehyde re-pollution.

The correct way to remove formaldehyde: the removal of formaldehyde by photocatalysts. Photocatalysis can decompose formaldehyde into carbon dioxide and water, greatly improving the safety and effectiveness of formaldehyde removal. After treatment, the air quality reaches the national standard, and you can stay with confidence!
