Formaldehyde has always been a problem in decoration. Not long ago, once the method of removing formaldehyde from photocatalyst was launched, it was discussed by many netizens. So, is the photocatalyst useful for removing formaldehyde ? How to make the photocatalyst more effective? Below, the editor will come and have a good chat with you about the use of the photocatalyst for removing formaldehyde !
1. Is photocatalyst useful for removing formaldehyde?
1. The principle of photocatalyst
There is another name for photocatalyst, called photocatalyst. Under light conditions, it can react with formaldehyde, benzene and other pollutants in indoor air to decompose them, so as to achieve the ultimate purpose of purifying the air.
2. How effective is the photocatalyst in removing formaldehyde
Take the experiment as an example. The experiment comes from the research and development department of a city's physical and chemical analysis center.
experiment one
Conditions: The photocatalyst was placed in the reactor, and the nitrogen oxide concentration in the reactor was 1.126 microliters.
â‘ Under light conditions: there is basically no change in the concentration of nitrogen oxides in the reactor;
â‘¡ Under light conditions: the nitrogen oxide concentration in the reactor decreased from 1.126 to 0.56 microliters;
It can be seen from the experiment that the photocatalyst still has the effect of removing harmful substances in the air.
Experiment 2
Our normal home glass has a certain anti-UV effect. So the experiment was changed to ultraviolet light.
â‘ Under the condition of ultraviolet radiation: the concentration of nitrogen oxides decreased from 1.126 microliters to 0.11 microliters;
â‘¡In the absence of ultraviolet radiation: the concentration of nitrogen oxides decreased from 1.126 microliters to 0.56 microliters;
It can be seen from the experimental results that the photocatalyst can play a greater effect under the conditions of ultraviolet irradiation.
Second, how to make the photocatalyst more effective in daily life
First of all, through the above two experiments, it is not difficult to see that the lighting conditions have a great influence on the photocatalyst. With or without light, there is a big difference in efficiency.
1. According to the experimental results, it is recommended that you buy sunlight photocatalyst series products.
2. Purchase photocatalyst products with ultraviolet lamps. Due to the need for UV lamps, the overall reaction area will be relatively reduced. One thing to remind everyone here, some friends will say to buy more UV lamps, this method is indeed ok. However, when using it, it is best not to be around. The light of the ultraviolet lamp will cause damage to the human skin, so it will be exposed to the sun in the hot sun.
Summary of the article: The above is the entire content of the photocatalyst prepared by everyone for removing formaldehyde and how to make the photocatalyst more effective. Photocatalyst products have a good effect in removing formaldehyde, but they are more focused on formaldehyde in the air, so there are still some limitations, everyone chooses at their discretion!
