VOC is the abbreviation of Volatile Organic Compounds (VOC). Volatile organic compounds are various organic compounds with boiling points of 50 to 260°C at atmospheric pressure. Among the more than 900 indoor chemicals and biological substances identified, VOC is at least 350 species (>1ppb), of which more than 20 are carcinogens or mutagens, and some long-term exposure can lead to cancer (lung cancer, leukemia) or lead to miscarriage, fetal abnormalities and growth retardation. Therefore, it has the greatest impact on pregnant women, children and other special groups. VOCs in indoor air mainly come from construction and decorative materials, such as paints, coatings, fillers, sealants, adhesives, floor coverings, wall coverings and furniture. The total VOC in indoor air is related to indoor temperature, relative humidity, loading of materials, number of air changes (indoor air circulation) and other factors In view of the high volatility of VOC, while using high quality wall paint with low VOC content, the newly renovated house should also be left vacant for a period of time to maintain ventilation and reduce the residual amount of VOC in the air. For newly renovated houses subjected to VOC pollution, some green plants are more effective natural deodorizers. NASA scientists found that under 24-hour lighting conditions, a pot of aloe vera can eliminate 90% of the formaldehyde contained in 1 cubic meter of air; a pot of hanging orchids can fireplaces, appliances, plastic products emitted carbon monoxide and nitrogen peroxide absorbed, while also absorbing 86% of the formaldehyde; tiger tail orchids and other large leaves of foliage plants can absorb more than 80% of the harmful indoor gases; and Azalea is the ability to adsorb radioactive substances. Therefore, in a 15-square-meter room, put two pots of hanging orchids or tiger tail orchids, you can keep the air fresh and away from the harm of VOC. Have you noticed the environment inside the car? Both high-end imported luxury cars, or domestic ordinary vehicles, are caught in the “odor door”, car interior air safety situation is worrying. The names of “polycyclic aromatic hydrocarbons”, “formaldehyde”, “benzene” and other toxic substances in the air inside the car is constantly stimulating people’s nerves, the car has gradually become a fearful car The trend of “toxic cave”. The issue of air safety in cars is not a new topic. According to March 15, 2013, the State Administration of Quality Supervision, Inspection and Quarantine announced the “2012 automotive product defect information complaints” shows that the odor inside the car has become one of the most concentrated problems of car owners complaints. Over the past few years, companies and models that have been exposed due to problems are common, although as early as March 2012, the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued the “Passenger Car Interior Air Quality Evaluation Guide”, but due to regulatory and other reasons, the problem of automotive interior air safety has not been well resolved. At present, the simplest and most effective way to improve the air quality in cars is to let the toxic gases in the car as soon as possible. As if the new house after renovation needs to be idle for a period of time for ventilation, to be dissipated after the harmful gases before moving in, the car also needs more ventilation. In addition, regular cleaning of car air conditioning ducts, timely replacement of car air conditioning filters, the use of activated carbon adsorption and filtration, car oxygen bar, ozone, gas catalyst, photocatalyst and other ways to disinfection, can also play a role in improving the air quality inside the car experts also recommend that you should try to use the air circulation inside and outside the car to dilute the original toxic pollutants in the car. Even if the factory interior pollution is serious, as long as you insist on driving with the windows open, and more sunlight to accelerate the volatilization of toxic gases, at most only a few months of time, you can dissipate the pollutants inside the car. In order to eliminate the leather odor in the new car as soon as possible, you can choose, for example, activated carbon and other adsorbents to replace the car perfume, not only can play a relatively strong adsorption effect, but also no harm to humans.
