“The problem of air quality in cars has now become a concern of the entire society.†Song Guangsheng, director of the National Indoor Environment and Environmental Products Quality Supervision and Inspection Center, spoke this morning on an interview with Gasgoo.com. In response to reports recently released by the World Health Organization that air has become the first class of carcinogens, and Ford experts' speeches that the air pollution in cars is far beyond imagination, Song Guangsheng pointed out that the air quality in the car has risen to a global topic, not only for Ford. Such international car companies are concerned that in recent years, the attention of the Chinese government, enterprises, and consumers to the air quality in the car has generally increased.
Song Guangsheng said that there are many sources of air pollution in the car, including the processes and materials in the automobile production process, special materials for heat insulation and shock absorption, and automotive interiors. These materials are harmful to human health by volatilizing toxic chemicals, especially under high temperature conditions.
Compared with the mature automobile industry in foreign countries, China's automobile industry started relatively late, and the control standards for air quality in cars are still at the stage of exploration. Song Guangsheng pointed out that at present there is no international standard for hazardous substances in vehicles as a reference, and China has issued a “Guide to air quality in passenger vehicles†for air quality in the car in March 2012. However, this guideline is still a recommended standard at this stage and it is not mandatory.
However, Song Guangsheng pointed out that the government is gradually increasing its strict monitoring and control of the atmospheric environment and the car's toxic chemicals such as nitrogen oxides, ozone, and VOCs. On the day of the reporter's interview, Song indicated that he was participating in a conference on the air quality in cars conducted by the relevant departments. “The Ministry of Environmental Protection has confirmed that it will start to revise the existing “Guidance on Air Quality Assessment for Passenger Vehicles†in 2014 and will issue mandatory standards for air quality in vehicles in 2015.†Song Guangsheng disclosed to reporters in an interview.
Previously, some car companies and experts said that air pollution in the car was unavoidable, because some chemical pollutants remained in the production process and materials, and these materials are often necessary materials for automobile production. In response, Song Guangsheng told reporters that the pollution of toxic chemicals in cars is not uncontrollable. For example, in the automotive production process, the use of plastics and paints can be reduced. In the automotive interior, raw materials can be used without pollution. In other words, car companies can find alternative solutions without reducing the physical costs of the original materials, and finally they are supplemented with the external conditions such as ventilation and purification devices, so that they can achieve healthy and safe interior air quality.
This means that once the mandatory air quality standards are implemented, vehicle manufacturers and downstream component suppliers can no longer use raw materials containing toxic chemicals for technical reasons. This will be a big test for the current vehicle companies and their entire downstream suppliers. 
Car air quality mandatory standards will be introduced in 2015
Canvas matting agent is a chemical agent used to treat canvas materials to produce a matte effect on the surface. It is mainly
used in textiles, clothing, decorative materials and other fields to increase the beauty and touch of the fabric.
Canvas matting agent usually contains a variety of ingredients, including but not limited to:
Matting agent: This is the main ingredient, responsible for reducing or eliminating the gloss on the surface of the fabric, making the fabric look more natural and comfortable.
When using canvas matting agent, it is usually necessary to dilute it in a certain proportion and apply it to the surface of the fabric by spraying, dipping, brushing, etc. After a specific drying process (such as natural drying or drying), the fabric can obtain the ideal matte effect.
It is worth noting that different types of canvas and application occasions may require matting agents with different formulas, so when selecting and using them, they should be appropriately adjusted according to specific needs and fabric characteristics. At the same time, considering environmental protection and human health factors, some new types of non-toxic, low-volatile organic compounds (VOCs) canvas matting agents are gradually being developed and applied.
