According to China standard Indoor Air Quality Standard (GB/T 18883-2002), the limit of formaldehyde in indoor air is 0.08 mg/m? . Compared with the standard limit concentration, the formaldehyde concentration between 0.5 and 0.6 has exceeded the standard upper limit. Therefore, living in such an environment has certain health risks, and long-term exposure to high-concentration formaldehyde environment may lead to throat discomfort, headache, eye pain, allergies and other discomfort. In addition, different people have different sensitivity to formaldehyde. Some people are sensitive to formaldehyde, and even if the concentration of formaldehyde is relatively low, uncomfortable reactions may occur. People who are sensitive to formaldehyde may feel the impact even if the concentration is lower than the standard limit. In order to help you remove formaldehyde quickly, let me explain several methods I use in dealing with formaldehyde, which can be used by friends in need.
First, strengthen ventilation.
Ventilation is essential for indoor in addition to formaldehyde, but it should be strengthened when the outdoor wind is not strong enough. At this time, you can buy a large industrial fan with more power to help blow away harmful gases in the house, which can speed up the circulation of indoor air and is of great help to clean up indoor decoration pollution.
Second, physical adsorption.
Activated carbon and Rui? Stone is a commonly used adsorption material, scientific and effective, like Rui? Stone, activated carbon and other substances have developed pore structure and specific surface area, which can adsorb formaldehyde into their own pores. Activated carbon is only adsorbed, so it is easy to saturate. Stone is decomposed while being adsorbed, which can be used for 2-3 years without sun exposure and replacement, which is very convenient and saves a lot of time.
Third, Mu? Light? blue
It can make formaldehyde, which takes 15 years to completely volatilize, come out within one week and decompose into carbon dioxide and water. In the absence of any reaction conditions, formaldehyde, benzene, TOVC and other harmful substances can be continuously decomposed for 24 hours, and there are no harmful volatiles and secondary pollution during the reaction. It can solve the problem of indoor decoration pollution from the root, and will not destroy the internal and surface structure of any substrate and affect the appearance.
IV. Water and scrubbing
The curtains in the bedroom are washed with water and washed with some laundry detergent. In particular, curtain carpet fabrics that can pass water must be soft-packed, and the surface of furniture should be wiped with water and cleaned with water.
Verb (abbreviation for verb) plant
Plants can not only effectively remove formaldehyde, but also cause no secondary pollution to the environment, which is one of the efficient and environmentally friendly methods. Plants that can absorb formaldehyde generally include green radish and chlorophytum. Putting a few pots of plants at home can not only absorb harmful gases, purify the air, but also beautify the environment.
Six, photocatalyst
It can decompose formaldehyde, an organic volatile substance, into substances that are harmless to the human body. When it comes into contact with oxygen and sunlight in the air, it will continuously release hydroxyl radicals and superoxide anions. But it is a chemical substance, so you need to pay attention to safety when using it.
To sum up, it is not difficult to remove formaldehyde as long as the right method is chosen, but a single method is not enough. We can combine several methods.
