Benzene pollution control of indoor air treatment!

Update Date: 20:21, November 11, 2018 Views: 56
The harmful gas in the home decoration, we hear the most is formaldehyde, many companies are also to indoor formaldehyde as the main business slogan. Is formaldehyde the only harmful substance in decoration? The answer is no, in addition to formaldehyde, there is a more harmful gas, that is benzene, benzene is often ignored, but in the World Health Organization, as early as 1993, benzene was listed as a strong carcinogen, is the main culprit leading to leukemia. Benzene pollution is generally rare. This is because as the country's increasingly stringent environmental protection requirements, benzene as a diluent is strictly limited to use, but in addition to benzene, benzene derivatives such as toluene, xylene often become substitutes for benzene, widely used in the production and use of paints and coatings. Therefore, we need to pay attention to the so-called toluene, xylene pollution. Today, we will introduce how to deal with benzene pollution in indoor formaldehyde removal company.
 
Excessive benzene will cause benzene poisoning
 
Toluene and xylene mainly exist in various paints, coatings, chemical fiber materials and organic solvents in the decoration process. If people inhale high concentration of toluene or xylene in a short period of time, the symptoms of central nervous system anesthesia will appear, which will lead to respiratory system failure and death. In the new decoration period, there will be more paint space, which will make people feel nauseous, dizzy and chest tightness The body is toluene or xylene. In China's "indoor air quality standard", the concentration of benzene should not be higher than 0.11 mg / m3, toluene and xylene should not be higher than 0.20 mg / m3. Pay close attention to excessive benzene pollution in areas where paint, chemical fiber and organic solvents are used in decoration.

In order to avoid excessive benzene pollution, the first thing is to avoid using building materials containing triphenyls in material selection. Water based paint and environmental protection paint should be used more. When applying putty and backing before pasting wallpaper, the decoration technology such as varnish should be avoided. The use of three benzene containing materials from the source is reduced. After finishing the decoration, the following methods can be adopted if benzene exceeds the standard:
 
1. Strengthen ventilation. Ventilation is the best way to quickly volatilize and release BTEX. Unlike formaldehyde, BTEX has a short volatilization period, which can volatilize more than 90% in a month. Therefore, ventilation is an ideal way to remove benzene pollution.
 
2. If the ventilation condition is not good, more activated carbon can be placed. The porous structure of activated carbon can capture and adsorb benzene molecules better than formaldehyde, because benzene series molecules belong to macromolecules and are easy to be adsorbed by activated carbon.
 
3. Professional indoor formaldehyde removal company to control benzene pollution. In the case of high benzene pollution, even ventilation, activated carbon and other methods can not be solved in a short time, while professional indoor formaldehyde removal companies can carry out source treatment of benzene pollution through advanced equipment and products, and decompose benzene into water and carbon dioxide without any secondary pollution. This professional indoor formaldehyde removal company's treatment method is currently the ideal way to control benzene pollution.
