HOW TO USE
NANO PHOTOCATALYST
At present, there are various methods for removing formaldehyde on the market, but the internationally recognized effective method for removing formaldehyde is mainly photocatalyst. Photocatalyst is a kind of catalyst, which can decompose formaldehyde, toluene, TVOC and other harmful organic substances into harmless gas under the action of light, so as to achieve the purpose of removing formaldehyde. So, how to use nano-photocatalyst?
How to use nano photocatalyst? Originally, titanium dioxide was solid and insoluble in water. The German R&D team developed a neutral and mild solvent, which perfectly dissolves titanium dioxide in the liquid, and then sprayed it on the place where formaldehyde needs to be removed through the atomizing nozzle. The stock solution containing nano-titanium dioxide is put into a well-designed bottle, and consumers can easily spray the stock solution on the surface of furniture that needs to be removed with one hand, which has successfully transformed the experimental results into practical products for removing formaldehyde in the hands of ordinary people.
In the beginning, the main material of the photocatalyst was nano-titanium dioxide. Because light is required to form a photocatalyst, sufficient light wavelength and intensity are required, which is what we call ultraviolet light, which limits the effect of titanium dioxide photocatalyst. After all, it is impossible to always have in order to solve this problem, researchers continue to experiment with visible light induction of photocatalysts, and finally found that the coordination chelation of nano-precious metals and photocatalyst materials can improve the separation efficiency of photogenerated carriers and inhibit the recombination of electron holes, and further Broadening the light absorption range, this is the later visible photocatalyst.
How to use photocatalyst?
Traditional photocatalysts can indeed only convert the energy of ultraviolet light. After half a century of research by scientific researchers, many cutting-edge photocatalyst technologies can also play an ideal role in removing formaldehyde under fluorescent lamps.
The common photocatalysts on the market are basically ordinary photocatalysts, and their photocatalytic efficiency is very low. What is really effective is the TIO2 nanoclusters modified in strict accordance with a certain proportion by using the characteristics of heavy metals that are easy to form electron holes. The critical wavelength of excitation photocatalysis extends to the visible light field, not only pure ultraviolet light can be excited. However, ordinary fluorescent lamps and scattered light from the sun can stimulate them to produce photocatalytic reactions.
Can Nano Photocatalysts be Used to Remove Formaldehyde?
After the photocatalyst was proposed in Japan in the 1960s, researchers around the world have never stopped improving the photocatalyst to remove formaldehyde. German Noh Rooheal has developed a formaldehyde remover with nano-titanium dioxide as thremovere main raw material. Originally, titanium dioxide is solid and insoluble in water. The NOH R&D team has developed a neutral and mild solvent, which perfectly dissolves titanium dioxide in the liquid, and then sprays it on the place where formaldehyde needs to be removed through the atomizing nozzle.
Can nano photocatalysts be used to remove formaldehyde? The photocatalyst itself is only a catalyst and does not directly participate in the degradation reaction. It mainly converts water or oxygen into strong oxidative active groups by absorbing light energy, and the strong oxidative active groups degrade air pollutants. side effect. Because the photocatalyst works mainly through light irradiation, it is only suitable for use in places with light. It is not effective when used in dimly lit or confined spaces such as drawers.
Titanium dioxide plays the main role in the photocatalyst. It can absorb light energy to generate an ion that can decompose formaldehyde, break the chemical bond of formaldehyde, and decompose it into water and carbon dioxide. It not only has no secondary pollution, but also has no side effects on the human body.
Can nano photocatalysts be used to remove formaldehyde? Originally, photocatalysts and the like can decompose formaldehyde when exposed to light, because the use conditions require sufficient light, and corresponding ultraviolet rays will also be required. At present, many cutting-edge photocatalyst technologies can also play an ideal role in removing formaldehyde under fluorescent lamps. How does the photocatalyst applied to life work?
HOW TO USE PHOTOCATALYST TO
REMOVE FORMALDEHYDE
In recent years, with the improvement of living standards, the decoration has become more and more luxurious, and the accompanying problem of excessive formaldehyde has become prominent, and excessive formaldehyde has also troubled many owners. Now a product called photocatalyst is very popular on the market. It is said to be one of the faster methods to effectively remove formaldehyde. Then, how to use photocatalyst to remove formaldehyde?
Photocatalyst is a general term for photo-semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide. Photocatalyst is a general term for photo-semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide. It is coated on the surface of the substrate and has a strong catalytic degradation function under the action of light, which can effectively degrade harmful air. At the same time, it can also play the role of eliminating a variety of bacteria, as well as deodorizing and anti-fouling functions.
Do a preliminary cleaning of the floor or furniture before spraying process
Spray the photocatalyst evenly on the surface
During the spraying process, be careful not to appear water droplets (keep distance between the nozzle & substrate surface between 40-55cm)
Do not clean after spraying. After three days, after the photocatalyst has formed a stable nano-film on the surface of the substrate, you can clean it, so that the effect will be more obvious
After completion, turn on the light or irradiated to the sun, ultraviolet light can be used to accelerate the activation of photocatalyst
The Advantages of Photocatalyst in Removing Formaldehyde
As a new technology for removing formaldehyde, photocatalyst has many advantages. Compared with various formaldehyde removal products on the market, the advantages of photocatalyst in removing formaldehyde are as follows.
Comprehensive
Photocatalyst can effectively degrade formaldehyde, benzene, toluene, xylene, ammonia, TVOC and other pollutants, and has high-efficiency and broad-spectrum disinfection performance, and can decompose and harmlessly treat toxins released by bacteria or fungi. In addition to being effective in decomposing organic pollutants such as formaldehyde, photocatalysts can also kill bacteria and viruses easily. In Japan, photocatalysts are widely coated on the surface of sanitary equipment and medical equipment, and new materials and products with antibacterial and antivirus are made. The killing effect on germs is remarkable.
Safety
Photocatalysts are mostly titanium dioxide, and titanium dioxide is listed by the US Food & Drug Administration as a white pigment for food. Titanium dioxide can be said to have penetrated into people's lives. It is found in cosmetics and food additives, which is enough to prove that photocatalysts are completely harmless and non-toxic. , harmless, safe and reliable for human body; the final reaction products are carbon dioxide, water and other harmless substances, which will not produce secondary pollution.
Persistent
We all know that the ingredients of formaldehyde remover are mainly chemical substances that can react with formaldehyde in time, and its composition determines its short-term and potential hazards. There may be some harmful components in the remover, causing secondary pollution, and its effective components will lose their effectiveness after the reaction is completed, but the formaldehyde in the artificial wood board has a long release cycle, which can be as long as 3 to 15 years. However, photocatalyst perfectly solves this problem. In the reaction process, it does not participate in the reaction itself, but only plays a catalytic role. It can be effective for a long time. Under the irradiation of light, it can continuously purify pollutants. It has a lasting and continuous effect. It is very practical for the treatment of persistent pollutants such as formaldehyde.
Efficiency
Photocatalysts use inexhaustible solar energy and other light energy to remove and purify diffused environmental pollutants at low concentrations.
