The formaldehyde odor at home exceeds the standard, is the photocatalyst useful?

Indoor air pollution is not only formaldehyde, but also benzene, toluene, xylene, ammonia and TVOC, but formaldehyde is more familiar because it is a class I carcinogens.

There are only two effective ways to remove decoration pollution: ventilation and professional treatment.

No matter what method is used to remove decoration pollution, the first thing to understand is the degree of pollution. Because the quality of the decoration materials used in the decoration process is uneven, even if all the decoration is made of environmentally friendly materials, it should be tested before moving in. Understand the degree of pollution in your home and then choose a reasonable removal method.

It must be said here that you must find a formal testing agency to do decoration pollution testing, the data error of the test box and handheld detector is very large, **News has also been reported, you can search on Tencent**: Is self-testing formaldehyde reliable? ）

Let's talk about ventilation first, this method is only suitable for houses that are not seriously polluted, if the multiple of the excess is too high, don't ventilate, and it may not be able to meet the living standard for two years. Although ventilation does not cost money, it is more time-consuming and laborious, and the house is vacant for a long time, so it is not recommended to use this method if you are in a hurry to move in. Moreover, it must be ventilated for a long time to have an effect, and the formaldehyde release cycle in furniture is as long as 3-15 years.

We must be prepared for a long-term battle with formaldehyde.

There is also a way is professional governance, indoor home environmental protection has matured after years of development, but there are fish in troubled waters in every industry. The following will introduce you to the commonly used treatment technologies of formaldehyde treatment companies in the market.

The first generation of formaldehyde removal technology: high-temperature fumigation.

Using the volatile characteristics of formaldehyde, benzene and other pollutants, the furniture is fumigated to increase the surface temperature of the furniture to 100-200 degrees Celsius, so that the formaldehyde is released faster. This method can only accelerate the volatilization of formaldehyde on the surface of furniture, but cannot volatilize the formaldehyde in the inner layer of furniture. The effect is okay in the short term, but the formaldehyde inside the furniture will be slowly released over time.

The second generation of formaldehyde removal technology: photocatalyst.

Photocatalyst is a catalyst that can decompose harmful organic compounds such as formaldehyde, toluene, and TVOC into harmless gases under the action of ultraviolet light, so as to achieve the purpose of removing formaldehyde. It is important to remember that the photocatalyst needs to react in the presence of light, and the more light it is, the better. However, in poor lighting or shady corners, the effect of this method in removing formaldehyde becomes limited.

The third generation of formaldehyde removal technology: air catalyst.

Like a photocatalyst, it is also a catalyst, but the difference is that the reaction medium of this catalyst is air. As long as it is in contact with the air, it can decompose harmful pollutants such as formaldehyde, benzene, toluene, xylene, ammonia, and TVOC. This solves some of the limitations of photocatalysts, and it can be said that the effect of governance is more thorough.

Moreover, the air catalyst agent will form a protective film on the surface of the furniture, which can prevent the continuous release of formaldehyde in the deep layers of the furniture.

In fact, formaldehyde scavengers will be more or less useful, but they have a good effect, and some of them are not obvious, there are generally about these categories, usually seen are bottled formaldehyde scavengers, the ingredients are generally not explained, so do not buy, may not be produced by regular manufacturers.

The photophyll I used before is good, people in the industry say that this is an upgraded material of photocatalyst, it is better to use, and then the taste at home is indeed much better in a week, and then I manage it myself, and it is slowly gone, you can also try it.

Hello, photocatalysts are useful in removing formaldehyde, depending on which one you choose.

Is it useful for photocatalysts to remove formaldehyde? Photocatalyst is a general term for photosemiconductor materials with photocatalytic function represented by nanoscale and titanium dioxide, and is one of the safest materials for controlling indoor environmental pollution in the world.

Now many people know that newly renovated houses need to remove formaldehyde, and photocatalyst is the latest fresh air product, which is favored by many owners who have renovated their new houses. Let's take a look at whether photocatalyst formaldehyde removal is useful. Of course, the application of photocatalyst in household formaldehyde removal has a certain effect, but it also has its limitations.

Under the irradiation of light, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis, which will decompose organic pollutants into non-polluting substances, so it has a strong function of removing formaldehyde and purifying the air. Under light irradiation, the photocatalyst can absorb light energy equivalent to the energy of the band gap, and the surface of the photocatalyst is excited to produce electrons and holes. These electrons and holes have strong reducing and oxidizing abilities and can react with water or confined oxygen to produce hydroxide radicals and super anion ions.

It is through the chemical effect of these ions that formaldehyde is removed from the air. Here I want to remind that the photocatalyst will only work under ultraviolet irradiation, and the ordinary indoor light is weak, and its strength and energy level are not enough to catalyze the photocatalyst, and the amount of decomposition is very limited, so the effect of directly using the photocatalyst for indoor formaldehyde removal is not ideal.

Useful. Photocatalyst As the name suggests, it is a substance that produces a catalytic effect with light, and it itself will not be decomposed or changed during the reaction. For example, photosynthesis in plants is a good example, and photophyll is a natural photocatalyst that promotes the synthesis of carbon dioxide and hydration in the air into oxygen and carbohydrates during photosynthesis.

The photocatalyst can convert light energy into chemical energy under illumination, which excites the surrounding water and oxygen molecules to ionize, presenting a valuable photoelectric effect. It can be decomposed, including formaldehyde, benzene, TVOC and other 114 kinds of organic matter, safe and non-toxic, allowed to be eaten, and also has the effect of antibacterial disinfection.

Useful, first of all, photocatalyst formaldehyde removal is indeed highly recognized in the industry and is the most widely used, but it cannot be denied that it has no drawbacks. For example, what I know is that the photocatalyst material originated from Japan, but Japan was not used at home at that time, only used outdoors, that is, it was worried that there would be secondary pollution, the response was not sufficient, and sufficient ultraviolet light was needed, and now although it has been upgraded, this problem has not been well solved. So there has always been research and development.

Photophyll is a new type of material developed on the basis of photocatalyst, which can be directly decomposed with formaldehyde without the participation of light, and can penetrate the inside of the plate to achieve the effect of root decomposition, without secondary pollution, extracted from plant extract, and is safer for families with mothers at home. It is also widely used by formaldehyde treatment companies and is more and more popular with consumers.

The analysis is as follows:

1. After the photocatalyst removes formaldehyde, it accelerates the volatilization of formaldehyde, and continuous ventilation is required. It can be removed in a short period of time.

2. Photocatalysts belong to the chemical category, it is normal to have a taste, and some will have crystal precipitation, so it is generally not recommended to use that in addition to formaldehyde, you can consider using some herbaceous plants, this pure plant extraction, decomposition and removal are not harmful, there is no secondary pollution, you can use some plants, nano live ores are placed and absorbed.

3. Photocatalyst is a new type of product widely welcomed by consumers in the market, it is a nano-level metal oxide material (titanium dioxide is more commonly used), coated on the surface of the substrate, under the action of light, it can produce a strong catalytic degradation function, and can effectively degrade toxic and harmful gases in the air.

Although the photocatalyst is used as a catalyst to participate in the decomposition reaction of formaldehyde, it is also a chemical substance, and it is normal to have a smell. However, it is best to use the latest generation of photocatalysts, because after adding platinum, the potential difference between the crystals can be excited, and it can catalyze the decomposition of formaldehyde even in the absence of light at night. This can better control the formaldehyde content in the room.

The volatilization of formaldehyde is accelerated, and continuous ventilation is required. It can be removed in a short period of time.

The effect of general formaldehyde removal products is still OK, but there are differences in deodorization, after all, formaldehyde is a specific substance, which can generally be removed, and if you want to remove the odor at one time, you need to choose high-end and expensive products.

Governance Approach.

1. Ventilation method: the largest amount of pollution released after the decoration has just ended, at this time, the effect of what activated charcoal flavor agent is not much better, the best way is to spray the whole Shibang and then open the window for ventilation. After the renovation of the new house is completed, it must be ventilated every day.

2. Plant law: Indoor proper cultivation of some spider plants and other green plants.

3. Decomposition method of pure herbal extract:

Using the principle of decomposition and catalysis, the main active ingredients of Quanshibang are refined through scientific proportioning and special compounding process. It has a super and long-lasting decomposition ability for decoration pollution. Formaldehyde volatilized from furniture and various panels and free in indoor air is efficiently captured and converted into carbon dioxide and water.

The most important thing is that it can penetrate deeply into the interior of the furniture board and decompose it, fundamentally solving the problem of formaldehyde.

Photocatalysts are also chemical substances, and it is normal to have a peculiar smell. Photocatalyst is the fastest way to remove formaldehyde, and many professional formaldehyde removal companies use photocatalyst to treat formaldehyde, but photocatalyst has a disadvantage, and it must be operated under light or ultraviolet irradiation. Now the latest generation of photocatalysts can excite the potential difference between crystals after adding platinum photopin, which means that formaldehyde can also be catalytically decomposed in the absence of light at night.

Photocatalyst is a general term for photosemiconductor materials with photocatalytic function represented by nanoscale titanium dioxide, which is coated on the surface of the substrate and produces a strong catalytic degradation function under the action of light: it can effectively degrade toxic and harmful gases in the air. It should be the reason for the decomposition, and more ventilation in the later stage.

Also pay attention when using it:

Photocatalyst materials originated in Japan, but Japan did not use them at home at that time, because they were worried that there would be secondary pollution, the response was not sufficient, and sufficient ultraviolet light was needed.

It has been well solved, photophyll is a new type of material developed on the basis of photocatalyst, which can be directly decomposed with formaldehyde without the participation of light, and can penetrate the inside of the plate to achieve the effect of root decomposition, and there will be no secondary pollution, extracted from plant extract.

It is safer for families with mothers at home. It is also widely used by formaldehyde treatment companies and is more and more popular with consumers.
