1. The principle of photocatalyst formaldehyde removal.
Photocatalyst is an environmental protection technology that uses light energy to decompose harmful gases such as formaldehyde. The principle is that when the photocatalyst coating is irradiated with light, electrons and positive ions are generated, and these electrons and positive ions are able to react with oxygen and moisture in the air to produce hydroxide radicals and negative oxygen ions with strong oxidizing properties. These strong oxidizing free radicals can decompose harmful gases such as formaldehyde into harmless carbon dioxide and water vapor, thereby purifying the air.
Second, the advantages of photocatalyst in removing formaldehyde.
1.Efficient formaldehyde removal: The photocatalyst can completely decompose formaldehyde and other harmful gases without secondary pollution.
2.Comprehensive purification: In addition to decomposing formaldehyde, photocatalysts can also remove other harmful gases and odors, such as benzene, ammonia, bacteria, viruses, etc.
3.Long-term effect: The decomposition effect of the photocatalyst will not be weakened by the passage of time, and as long as the coating does not wear out, it can be effective for a long time.
4.Safety and environmental protection: Photocatalyst is a non-toxic and harmless environmental protection technology, which is harmless to the human body and environmentally friendly.
3. The use of photocatalyst to remove formaldehyde.
1.Choose high-quality photocatalyst products: choose regular brands and reliable quality photocatalyst products, and pay attention to check the quality inspection report and certification certificate of the product and other relevant information.
2.Read the instructions for use carefully: Before using the photocatalyst, read the product manual carefully to understand the information such as the method of use, precautions and scope of application.
3.Clean the surface: Before using the photocatalyst, the surface to be treated needs to be thoroughly cleaned to remove impurities such as stains and oil stains on the surface.
4.Spraying photocatalyst: Follow the instructions in the product manual and use the matching watering can to evenly spray the photocatalyst on the treated surface. Generally, you need to spray twice, wait a moment after the first spray before spraying the second time.
5.Avoid direct sunlight: After spraying the photocatalyst, it is necessary to avoid direct sunlight so as not to affect the decomposition effect of the photocatalyst. In general, it is better to use photocatalysts in a well-ventilated indoor environment.
6.Regular maintenance: In order to maintain the long-term effectiveness of the photocatalyst, regular maintenance is required. Generally speaking, the surface needs to be photocatalyst sprayed every six months or so. At the same time, surfaces need to be cleaned regularly to remove accumulated dust and stains.
4. Precautions.
1.For newly renovated houses or new furniture and other items with high formaldehyde content, it is recommended to open windows for ventilation for a long time and use photocatalyst to achieve the best effect.
2.When formaldehyde treatment is carried out for the house that has been occupied, it is recommended to close the doors and windows for photocatalyst spraying, and then open the windows for ventilation for a period of time, so as not to affect the life and work of indoor personnel.
3.For some highly polluted environments or newly renovated offices and other places, it is necessary to carry out multiple treatments to achieve the desired effect. Therefore, it is necessary to judge the number of governance times according to the actual situation.
4.Photocatalyst formaldehyde removal requires a certain amount of light exposure to work, so the effect may be affected when used in a dark or sunless environment.
5.For some metal surfaces or smooth surfaces, special treatment is required to use photocatalysts, so it is necessary to read the product manual carefully and treat it as needed.
