Recently, a car exposure test conducted by a domestic institution has once again triggered public concern about the air quality inside the car. The "notorious" formaldehyde appeared in the test results. Many netizens have said that they are "drug-using" every day. In fact, in these volatile organic compounds, in addition to formaldehyde, there are various gases harmful to the human body such as toluene, acetaldehyde, and acrolein. It should be noted that the release of many harmful gases is related to temperature. For example, formaldehyde, the higher the temperature inside the car, the more the release of formaldehyde and other pollutants will increase. An expert in a chemical trading company said that if the vehicle is exposed to the sun for more than an hour, the pollutants in the vehicle will increase sharply and the driver will be forced to inhale toxic gases. Therefore, if it is not ventilated, the vehicle that has been exposed to the sun in the summer is actually tantamount to the "invisible killer."
The raw materials of most automotive interior parts are polymer materials. In order to facilitate the processing, some small molecule additives are often added in the production process to achieve better performance. In addition, some solvents, mold release agents, etc. are used in the production process, which are all possible sources of harmful gases. As a supplier, you should try to choose some materials that are relatively environmentally friendly and less harmful. For example, when choosing an adhesive, replace the solvent-based adhesive with water-based glue and hot-melt glue.
How to reduce the production of formaldehyde?
First of all, ventilation must be done frequently. Especially if the vehicle is exposed to the sun or parked in the basement for a long time, it must be ventilated first. Secondly, try not to use interior trims, such as car perfumes, seat covers, foot pads and steering wheel covers, because these things are not guaranteed in quality and are prone to harmful gases. In addition, when the owner uses the air conditioner, try to avoid long-term internal circulation. Switch the external circulation mode to keep the air in the vehicle and the outside world.
