How to remove formaldehyde

In today's society, air pollution has become the most important issue for people. In particular, indoor air pollution has attracted people's attention. As a result, air purifiers have become one of the household appliances that many families consider. But does the air purifier really eliminate formaldehyde as we imagine it? Is air purifier useful for removing formaldehyde? Many consumers have doubts about this. Let us first understand the principle of air purifiers: Air purifiers generally use multi-stage dust removal devices such as activated carbon, high-voltage electrostatics, and dust collectors to complete air purification. It drives the maple leaves through the motor in the purifier, so that the indoor air generates a flow cycle, and is filtered by the air purifier to achieve the purpose of air purification. In addition, the air purifier in the structure; clean to clean the air from coarse to fine, that is, the air first through the filter, filter out the larger dust, and then through the activated carbon filter to filter out the air in the smoke and air odor, etc. The particulate dust is adsorbed by high-pressure static electricity and other composite dust removal methods. Finally, negative ions are generated by the negative ion generator to make the air fresh and pleasant, and achieve the effect of air purification.

Indoor air pollution mainly comes from three aspects: pollution caused by the construction itself, such as certain building materials, radioactive contaminants due to the high radioactive background of the raw materials; pollution caused by interior decoration materials and decoration process, such as sheet and chemical fiber Carpets, wallpapers, etc., especially the pollution of low-grade materials are more serious; the pollution brought by furniture and home appliances, such as the release of formaldehyde from panel furniture, and the pollution of benzene from the fabric sofas. At the same time, scientific research shows that the above materials contain more than 300 kinds of volatile organic compounds, of which the most important and most harmful are formaldehyde, benzene and total volatile organic compounds. These harmful gases not only cause serious damage to people's health, but also have long-lasting volatility and are difficult to remove.

At present, consumers have some misunderstandings about air purifiers, thinking that all air purifiers can remove formaldehyde. But in fact, it's not. Not all air purifiers have the function of removing formaldehyde, especially some imported products. Song Guangsheng pointed out: "An enterprise has selected many well-known brand products from abroad to send to Chinese inspection agencies because it wants to sell air purifiers. The results show that these air purifiers basically cannot solve the problem of formaldehyde pollution. If you want to pass an air purifier In addition to formaldehyde, consumers have to ask when buying."

Thixotropic Agent

Thixotropic agent is a highly effective mineral rheological agent, which can be used with cellulose ether to improve the constructibility and resistance to flow in polymer mortar products. When added to the Resin, it can make the resin glue liquid have a higher consistency at rest and become a fluid substance of low consistency under the action of external force.

Our company has a perfect sales network, fast logistics services, deep cultivation of new material industry, and actively expand business at home and abroad. We strive to find thousands of positions in the world's new materials industry.
