The harm of formaldehyde is well known. Nowadays, newly decorated rooms will have more or less formaldehyde residues, leading to indoor formaldehyde exceeding the standard. The detection and treatment of indoor toxic and harmful gases exceeding the standard is a very difficult problem before us. We should take timely measures to reduce the content of formaldehyde to a lower level to reduce the harm to human body. For formaldehyde exceeding the standard in Shanghai, Formaldehyde removal in Shanghai office The problems of formaldehyde removal, air purification, odor removal and formaldehyde removal in Shanghai's new houses are as follows: Formaldehyde removal method
1、 Tools/raw materials: natural bamboo charcoal, onion, white vinegar, formaldehyde scavenger.
2、 Steps/Methods Place onions in the corner of the room. Cut onions into pieces and put them in every corner of the room, which is more effective for formaldehyde adsorption. When the onion water evaporates, the effect of absorbing formaldehyde will be lost. It should be renewed in time. However, it only plays a temporary role in removing formaldehyde, and cannot completely remove formaldehyde.
3、 Place natural bamboo charcoal. Natural bamboo charcoal has a strong adsorption effect on many toxic substances. You should buy authentic bamboo charcoal and put it in the house, and put more everywhere. But it should be noted that bamboo charcoal benzene The system has a certain effect and can absorb some formaldehyde, but the effect is not very obvious.
4、 Add some white vinegar. Buy some high-quality white vinegar and pour it bowl Put it in the corner of the room and replace it every 10 days or so. Although it is convenient and simple, it can only play a certain role in formaldehyde removal.
5、 Use cactus, tortoise shell bamboo, aloe and other plants to remove formaldehyde. Put more tortoise shell bamboos, aloes, and hanging orchids in the room, and they will slowly absorb formaldehyde and other harmful substances over a long period of time. Although it has a certain effect, it can only play an auxiliary role in removing formaldehyde.
6、 Use special formaldehyde remover. This is a fast and complete method to remove formaldehyde. For example, air purifier has good effect. Although the cost is relatively high, it is expensive to buy and cheap to use. Air purifier is made of pure natural nanometer Material, no secondary pollution, good effect. But there are also disadvantages, that is, the price is more expensive than activated carbon, and the effective time is not as fast as formaldehyde scavenger. However, it is only effective to choose high-quality products. Try to buy them in formal malls or exclusive stores. If the formaldehyde and other pollutants are removed for a long time, it should be started without consideration window With ventilation and sun exposure, although the short-term effect is good, there is no cost. However, long-term ventilation is required to completely remove formaldehyde (usually 2-3 years), and it is not possible to completely remove formaldehyde by opening windows for several months.
7、 Note: It is recommended to use the above method at the same time, plus light catalyst products, formaldehyde scavenger, etc., so that formaldehyde can be completely removed. Catalyst method: the photocatalyst and air catalyst used by Shanghai Puris Indoor Environmental Pollution Control Center are liquid products containing nano titanium dioxide that are sprayed indoors for Shanghai indoor air pollution detection wall Or on the surface of furniture materials, titanium dioxide is used as a catalyst. The photocatalyst needs to remove formaldehyde from the Shanghai office under light conditions. The air catalyst does not need light conditions to actively decompose harmful air in objects into strong oxidizing superoxide and hydroxyl groups to oxidize pollutants into carbon dioxide and water, So as to achieve a better effect of treating the symptoms and root causes of toxic and harmful gases.
