How about nano photocatalyst formaldehyde scavenger

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

Photocatalyst is a nano-scale two.

The principle of photocatalyst formaldehyde removal reaction.

A general term for photosemiconductor materials with ultraviolet photocatalytic function represented by titanium oxide.

Under the irradiation of ultraviolet 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) and carbon dioxide (CO2), so it has strong sterilization, deodorization, mildew, Anti-fouling, 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 photocatalyst is generally sprayed on the surface of the substrate to form a protective layer, seal the formaldehyde and catalyze the decomposition of formaldehyde, but it will oxidize, wear and tear for a long time, and the formaldehyde will leak, and the photocatalyst must be irradiated by light or ultraviolet rays to have an effect. Therefore, the general photocatalyst is used in the industrial formaldehyde removal is more, for the removal of formaldehyde in the family, photophyll is generally selected, photophyll is also a catalyst, but compared with the photocatalyst, this does not require the participation of light, photophyll is derived from the photosensitive factor in the plant, the removal efficiency of formaldehyde is faster and more efficient, and there is no secondary pollution, it is a better choice.

Photocatalyst formaldehyde removal still has a certain effect, photocatalyst is mainly made of nano-scale titanium dioxide solution, and this kind of liquid is sprayed on the surface of the substrate in the spray construction technology.

In this way, under the condition of light, the substrate will have a catalytic reaction with the moisture in the air, so that the oxidative decomposition can be exerted, and the production of reactive oxygen species and hydroxide groups will be promoted. Through the strong redox ability of ions, formaldehyde and other harmful substances are decomposed, and the products of decomposition are carbon dioxide and water.

Precautions for use.

This film does not participate in the reaction, it can be said that there is no arbitrary or first consumption, as long as the surface of the substrate is not damaged, formaldehyde can be removed for a long time. Moreover, the photocatalyst also has the effects of deodorization, sterilization and mildew prevention, as well as air purification, which can be said to be an ideal material for removing formaldehyde at present.

Nowadays, the sol technology of photocatalyst is becoming more and more mature, and the adhesion of many manufacturers and imported photocatalyst sol products has been greatly improved. Spraying can be attached to the surface of furniture for at least ten years, because the photocatalyst can carry the formaldehyde released by continuous and effective decomposition, which plays a role in treating both the symptoms and the root causes.

Photocatalyst removal of formaldehyde will not produce the best situation, but the premise is that you must choose a regular product, and you must not be greedy for a small bargain. Because as long as the photocatalyst is treated once, it can be worry-free for at least ten years.

Formaldehyde can be said to be one of the toxic gases that people hate very much, its existence has an impact on our health, nano photocatalyst is now a more effective way to quickly remove formaldehyde in the middle of the home, let's go to find out:

What is a nanophotocatalyst?

Nano photocatalyst refers to a substance that does not undergo chemical changes under light, but can promote chemical reactions, and its function is like chlorophyll in photosynthesis. Anatase nano-TiO2 is the most important photocatalyst material, when it absorbs energy from sunlight or other light sources, the electrons on the surface of the particles are activated and escape from their original orbits, and positively charged holes are formed on the surface. The escaped electrons are strongly reducible, and the holes are strongly oxidizing, and the two react with water vapor in the air to form reactive oxygen species and hydroxide radicals.

Reactive oxygen species and hydrogen and oxygen radicals can oxidize and decompose most organic matter, pollutants, odors, bacteria, etc. into harmless carbon dioxide and water.

Nano photocatalysts are widely used in indoor air purification, sewage treatment, coatings, cosmetics, plastics, textiles, ceramics, glass, deodorization, disinfection and sterilization and other fields.

Nano photocatalyst to remove formaldehyde:

1. Is it reliable for nano stupid beam photocatalyst to remove formaldehyde?

Nano photocatalyst is an ideal new product in indoor air purification, which has the effects of sterilization, deodorization and mildew prevention. The new generation of nano photocatalyst is a high-performance and multi-functional indoor air purification nano photocatalyst product composed of natural polar mineral materials, refined by wet ultra-fine processing dry beam method, and then compounded with nano photocatalytic, inorganic antibacterial and other materials. Efficient removal of formaldehyde, sterilization, disinfection, deodorization, mildew, can effectively decompose and remove formaldehyde, benzene, ammonia and TVOC and other harmful gases and germs, to achieve the purpose of indoor air purification, is the best indoor air purification green products to remove formaldehyde.

2. Method of removing formaldehyde by nano photocatalyst:

When using nano photocatalyst for indoor air purification, it is recommended to use a compression (more than 3kg) motor spray gun, and the nozzle is preferred. Clean the surface of the object before spraying.

The nozzle is 30 45cm away from the surface of the coated object, and the coating surface is 60-70m2 kg for the best effect. The nozzle is 30 45cm away from the surface of the coated object, and the whole area is sprayed uniformly as the principle, and the coating surface is 8m2 100ml as the best effect, and the second nano photocatalyst can be sprayed after it dries as needed. Nano photocatalyst is now the best green product for indoor formaldehyde removal, which can quickly remove formaldehyde from furniture, so you should pay attention to the decoration of the home, there will definitely be a certain amount of pollution in the decoration of the home, and you should know how to remove formaldehyde in advance.

Photocatalyst materials are uneven, some are good and some are bad, bad materials are lower quality and will have secondary pollution, and better materials can choose Huankang aldehyde removal enzyme materials.

Huankang aldehyde removal enzyme material belongs to German quality, not a photocatalyst, it is a different material from ordinary photocatalyst. Huankang aldehyde removal enzyme is a material with adsorption, locking and decomposition of harmful substances, does not require ultraviolet participation, and has a small nanoparticle size, can be decomposed day and night, and will actively adsorb formaldehyde inside the board furniture to form a long-term protective film, belongs to the high-quality material, belongs to the epoch-making material product application, so it is a good formaldehyde removal material.

There are other ways to remove formaldehyde, such as:

1. Air exchange method: air exchange is ventilation, the higher the indoor and outdoor air exchange rate, the better the effect of reducing indoor pollutants.

2. Physical adsorption method: the use of activated carbon and other products to adsorb harmful gases, and at the same time assist ventilation, which can effectively improve the effect of removing pollution, and better is the decomposition and removal of Yeguang mud materials.

3. Plant purification method: green plants used to decorate the living environment can also purify indoor air. For example, ivy, iron tree spider plant, aloe vera, etc.

Now there are many methods to remove formaldehyde, which are roughly divided into ventilation, adsorption, and decomposition according to the principle of formaldehyde removal.

1. Ventilation. Natural ventilation: economical and environmentally friendly, with high efficiency in removing formaldehyde. Ventilation is most needed in the morning, with at least 1 hour of intermittent ventilation over a 12-hour period.

Forced ventilation: The fresh air system is commonly used, which has a good effect on removing formaldehyde. Composed of air supply and exhaust system, it discharges indoor pollutant gas and sends fresh air to the outside, and the ceiling-type full heat exchanger is the current mainstream fresh air system scheme.

2. Adsorption. Commonly used is activated carbon, which is a molecular sieve with tiny internal pores capable of adsorbing various substances, including formaldehyde. If you have used activated carbon to remove formaldehyde, please win by quantity, not by quality. The adsorption saturation time is uncertain, mainly depending on the pollution degree of indoor formaldehyde, benzene and TVOC.

3. Decomposition. Photocatalyst: Photocatalyst has the best efficiency in removing formaldehyde under ultraviolet light. Ordinary photocatalysts are not suitable for indoor use because there are almost no indoor ultraviolet rays; As for visible light photocatalysts, the formaldehyde removal efficiency is unknown, and it needs to be sprayed by professionals, so it is not recommended to buy them yourself.

Formaldehyde scavengers: ammonia, chlorine dioxide, hydrogen peroxide, etc. are commonly used, and some rely on formaldehyde to be easily soluble in water to achieve the formaldehyde removal rate in the experimental cabin. Formaldehyde removal efficiency is mostly high, but it can be harmful to the human body and furniture.

Purple plus black: Purple plus black to remove formaldehyde is also oxidative decomposition of formaldehyde, and the efficiency of formaldehyde removal is high. The main thing that plays a role is that the amethyrite particles are oxidizing and decompose formaldehyde, and the granular products are harmless to the human body and furniture.

The photocatalyst is a nano titanium dioxide photocatalyst, and the formaldehyde scavenger is a chemical reagent that can directly react with formaldehyde.

Useful, personally I think it works very well. I used this photophyll product myself, and it works well in combination with the following method:

1. Wipe the furniture with salt water to remove the smell.

2. The temperature is high in summer, and the formaldehyde is released, and more ventilation can ventilate a part of it.

3. Good photophyll materials to decompose, photocatalysts and other photocatalysts can decompose formaldehyde when exposed to light, and there are more industrial applications for removing formaldehyde, and photophyllin is a formaldehyde catalyst extracted from plants, which will be faster and safer, and more suitable for use under family conditions.

4. After removal, you can see if there is still a smell, and put some algae materials for long-term absorption.
