Background

VOCs are organic (carbon-based) gases, also known as hydrocarbons, emitted by many different products. The evaporation of VOC is caused by sufficient pressure. Common sources of volatile organic compounds in the room are decorative building materials, carpets, printers, furniture, paint thinners, glues, cosmetics and certain sprays, and also plastic products. According to the environmental protection agency's report, if there is not enough ventilation equipment to circulate the air and VOC exists indoors, the indoor air pollution level will be as much as 10 times more severe than the outdoor air. The main components of VOC are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, which include: benzene series, organic chloride, freon series, organic ketone, amine, alcohol, ether, ester, acid and petroleum hydrocarbon compound. VOC is the abbreviation of volatile organic compounds, and the chemical substances (except heavy metals) harmful to human bodies in the wall paint are VOC. These volatile organic compounds include formaldehyde, ammonia, ethylene glycol, esters, and the like.
