Can a newly renovated house use photocatalyst to remove formaldehyde? What is the effect after use?

Formaldehyde in new houses is mainly used in: new furniture, floors, walls, wallpapers, etc., and the hazards of formaldehyde are still many. It is advisable to take precautions; If the body has obvious dizziness, fatigue, nausea, etc., it is necessary to stay away from this environment and breathe more fresh air, and then seek serious medical treatment.

The photocatalyst we know actually has certain drawbacks in removing formaldehyde, which requires ultraviolet light irradiation to have an effect, and it will cause secondary pollution if you are not careful. However, photophyll is an upgraded material of photocatalyst extracted from the plant body, which can be directly decomposed without light, and it adds a decomposition catalyst and penetrant, which can better penetrate and decompose the formaldehyde pollution inside the furniture board, and the removal rate can reach 99%, which is a formaldehyde removal material widely used by decoration management companies.

First, let me tell you: photocatalyst is reliable in removing formaldehyde.

If it is not reliable, why do formaldehyde scavenger products, in which photocatalysts account for the majority, because in principle, it has more advantages and has won the recognition of most people.

For example, some purifiers say that a photocatalyst module has been added to the inside of the machine, and it seems that the photocatalyst should be the star product in addition to formaldehyde. Whether it is from the theoretical scientific basis (literature reports, experimental results) and practical application (most of the air treatment industry uses photocatalysts and has obtained good results), the effect of photocatalysts can decompose formaldehyde and other pollutants is certain and undoubted.

Second, what are the shortcomings:

1.Hard injury Restrictions on use conditions (light intensity, which is greatly affected by ultraviolet wavelength, cannot meet the needs of families that use at night or with limited light).

2.Domestic production technology The cost of nanoscale titanium dioxide is too high.

In fact, formaldehyde cannot be completely removed, and formaldehyde also belongs to the type that is slowly released. Therefore, according to the characteristics of formaldehyde, one was developed.

Nano aldehyde removal enzyme can be a good treatment of formaldehyde, and there is no harm or anything, there is no secondary pollution, it can be said that it is the best product in addition to formaldehyde, but it is metal, cloth, wallpaper or something can not be used to remove formaldehyde, no one is perfect, of course, there is a defect that can not be removed from metal, but it can be adsorbed with some live ore.

It is recommended to try activated carbon, coconut carbon is a new type of activated carbon, is a new process to make activated carbon, is a coconut shell as raw material, after high temperature activation, carbonization treatment, while loading photocatalyst, carbon fiber made of a new type of activated carbon, can adsorb formaldehyde, benzene, ammonia and other toxic and harmful nano-scale small molecule polar substances in the air, with fast adsorption speed, for polar molecules, can be recycled.

If you have to choose a reliable one, it's okay, when the photocatalyst decomposes organic matter, there will be different decomposition products. Carbon and hydrogen compounds, the final decomposition products are carbon dioxide and water, organic compounds containing ammonia and nitrogen, the final decomposition products are nitric acid or nitrate, and the final decomposition products of organic compounds containing sulfur and sulfhydryl groups are sulfuric acid or sulfate. When a large amount of sulfate and nitrate remain on the surface of the nano titanium dioxide crystal, the nano titanium dioxide particles will be surrounded and lose their photocatalytic properties, which is the photoetching effect of the photocatalyst.

It can be seen that the validity period of Mayan blue light catalyst to purify the air depends on the environment in which it is used, the more pollutants in the environment, the faster its photo-erosion occurs, the faster it fails, and the purer the air in the surrounding environment, the slower the photo-erosion occurs. In a typical home or office environment, photoerosion will render the photocatalyst ineffective in 1-2 years.

It is recommended to test it, this is hard to say. If you are still not at ease, it is recommended to put some leaf mud in the house and spray some light phyll or something.

Photocatalysts can decompose formaldehyde when exposed to light, and are used in industry to remove formaldehyde, and photophyll is a formaldehyde catalyst extracted from plants, which will be faster and safer, and more suitable for use under family conditions.

Photophyll is extracted from plants, which can enhance the photosensitivity of plants and improve the light sensitivity of photocatalysts. To make up for the weakness of photocatalysts, photophyll can also play a very strong formaldehyde removal effect even in indoor and non-light environments.

How long can you stay in this is uncertain, this needs to detect the indoor formaldehyde content, if the formaldehyde content is greater than milligrams per cubic meter, then it must not be occupied. And you can also buy some photocatalyst to remove formaldehyde, and now the platinum photocatalyst can also catalyze the decomposition of formaldehyde under the condition of no light at night, which can ensure 24-hour operation, and the effect can be more significant.

Generally, you don't use photocatalyst for more than half a year to move in, if you use photocatalyst, it depends on the situation at home, under the condition of not understanding the situation, no one can say how long it will take to move in, but photocatalyst is really helpful, I moved in after a month, basically no formaldehyde. Another thing you know is that photocatalysts can fully decompose harmful substances such as formaldehyde when there is light, so you should usually keep enough light, open the curtains, and let the sunlight fill your room. There are also more windows to let out the smell, which is also very important.

Hope it helps.

Photocatalysts have a good degradation and killing effect on unstable compounds of medium and low molecular weights and most of the germs, including formaldehyde.

Photocatalyst is a portmanteau of light [photo=light] + catalyst.

Photocatalyst is a general term for photosemiconductor materials with photocatalytic function represented by nanoscale titanium dioxide.

Under the irradiation of light, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis, producing free hydroxide groups and reactive oxygen species with strong oxidation ability, with strong photoredox function, oxidative decomposition of 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 pollution-free water (H2O) and carbon dioxide (CO2), so it has strong sterilization, deodorization, mildew, anti-fouling and self-cleaning. Air purification function.

Photocatalysts have a good degradation and killing effect on unstable compounds of medium and low molecular weights and most of the germs, including formaldehyde.

The release period of formaldehyde is 3-15 years, and the use of photocatalyst to remove formaldehyde depends on the situation of your home, and it can be decomposed with some good materials photophyllin.

1.Open the window for ventilation and put the water with vinegar in the ventilated room2Wiping furniture in salt water can well remove formaldehyde.

3.Special air fresheners are used, which are generally sold in supermarkets.

If you want to know when you can move in, it is recommended to test it with a Qingyi test box, the national standard is that you can move in, if the formaldehyde exceeds the standard, it is recommended to use the following methods to remove formaldehyde:

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 through the physical adsorption method, there is no chemical component pollution, and there are nano-level adsorption porosities in materials such as coconut carbon, 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. Put some tea, grapefruit peel, and fruit, which are all old methods and not very well-founded.

It is best to check before moving in, and you can't live if it exceeds milligrams per cubic meter, so how long you can move in can't be fixed. Traditional photocatalysts form a protective layer on the surface of the substrate to seal formaldehyde and catalyze the decomposition of formaldehyde. The new generation of platinum photocatalyst adds platinum photocatalyst, which can excite the potential difference between crystals, and can catalyze the decomposition of formaldehyde under the condition of no light at night.

Generally, the staff who go to the management will inform the relevant matters, and the effect is different according to the product, and the check-in time is also different.

Photocatalyst is the fastest way to remove formaldehyde, many formaldehyde removal companies also use photocatalyst to treat formaldehyde, photocatalyst sprayed on the substrate, will form a protective layer, first seal formaldehyde, in the catalytic decomposition of formaldehyde, the photocatalyst itself is involved in the reaction, just as a catalyst. However, after a long time of oxidation and wear, formaldehyde will leak, which requires frequent post-processing, and the previous photocatalyst can only work in the case of light, and now the third platinum photocatalyst will also work in the case of no light at night, but after several treatments, the indoor formaldehyde content will be controlled.

It's basically tasteless for a week.

Half a month is almost, but pay attention to the following: 1. Formaldehyde will be released continuously, don't think that it is good to treat it thoroughlyThe label is harmful to the body. 2. Formaldehyde can be dissolved in water, so use a water cup with a lid at home to avoid formaldehyde accumulating in the water cup for a long time and causing harm to the body.

3. Don't use plants to control formaldehyde alone, the adsorption capacity of plants is still very slow, if there is only a small amount of formaldehyde at home, it is more appropriate to use plant treatment. 4. Put activated carbon at home to absorb formaldehyde, pay attention to drying it outdoors once a month to release the adsorbed harmful substances, otherwise it will be released again to produce secondary pollution.

Follow-up treatment methods: 1. Ventilation, ventilate more at the possible time to release formaldehyde. 2. Photocatalyst and photophyll spraying.

The latter is a pure plant extract, which can be decomposed without light, and is safe and harmless. 3. Yeguang mud material is an upgraded material of activated carbon, which can be adsorbed for a long time without drying and is not saturated for recycling. 4. The functional air purifier can filter out some formaldehyde and other harmful gases.

After removing formaldehyde, you can move in about 3 to 5 months, and you should always keep the house ventilated, and you should also put some green plants at home, such as spider plant, tiger piran, which can effectively remove formaldehyde, and the residual plants are used as long-term green plants at home. And also put some activated carbon, which must be used for a long time, and it will also be good to adsorb and eliminate residual substances.

There is no specific time for this, it is best to test it before moving in, more than milligrams per cubic meter can not be checked-in, more than milligrams per cubic meter, it is also not allowed to allow pregnant women and children to stay.

In fact, photocatalyst is the fastest way to remove formaldehyde, and many professional formaldehyde removal companies use photocatalyst to treat formaldehyde, but photocatalyst has a drawback, 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.

This has nothing to do with time, it is best to test the formaldehyde content in the room, more than milligrams per cubic meter can not be occupied, if there are pregnant women or children, more than milligrams per cubic meter can not be occupied. It depends. The photocatalyst will form a protective layer on the surface of the substrate, seal the formaldehyde, and catalyze the decomposition of formaldehyde.

However, it must be exposed to light or ultraviolet rays before it can be operated. Moreover, after a long period of wear and oxidation, there will also be formaldehyde leakage, so it has been treated many times.

The latest generation of platinum photocatalyst can excite the potential difference between crystals after adding platinum to the photocatalyst, so that it can work under the condition of no light at night, and better control the content of formaldehyde in the room.

Spray with a plant extract of diallin, which does not require the participation of light, and is environmentally friendly and green, and the most important thing is that it is easy to remove quickly. It can effectively remove the formaldehyde gas separated in the room, and at the same time purify the air.

It is better to use plants to remove formaldehyde, and you can use a few pots of pothos and spider plants indoors, and open more windows for ventilation. The principle of photocatalyst is the same, photocatalyst needs ultraviolet light to participate in order to decompose, and formaldehyde can also be decomposed without the participation of light, which is very useful.

It is better to open the window for ventilation, what brand of photocatalyst you said is better, it is not easy to say, it feels almost the same, my home is finished with a plant extract of Dialin to spray, this does not need the participation of light, but also environmentally friendly green, the most important thing is that the removal is very easy to use, after the decoration at that time people into the house feel a sore throat, formaldehyde is too much exceeded, sprayed that basically into the taste, the feeling is obvious. In addition, let's ventilate more in the new home. There should be nothing else, I hope it can help you.

The photocatalyst is the same, there is nothing particularly good, the photocatalyst needs ultraviolet light to participate in the decomposition, it is recommended to use cyclokang aldehyde, this is an improved version of the photocatalyst, it can be locked and decomposed, and the formaldehyde can also be decomposed without the participation of light, which is very easy to use.

The best effect is to open the windows for ventilation, other methods can only play a supporting role.
