On October 23, Song Guangsheng, director of the National Indoor Interior Environment and Environmental Product Quality Supervision and Inspection Center, said in an interview that "air quality problems in the car have become a concern of the whole society."
Song Guangsheng said that there are many sources of air pollution in the car, including the process and materials in the car 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 at high temperatures.
Compared with the mature automobile industry in foreign countries, China's automobile industry started relatively late, and the control standard for the air quality inside the vehicle is still at the stage of exploration. Song Guangsheng pointed out that there is currently no standard for harmful substances in the car as a reference in the world, and China has introduced the "Guidelines for Air Quality Assessment in Passenger Cars" for air quality in the car in March 2012. However, the guide is also a recommended standard at this stage and is not mandatory.
However, Song Guangsheng pointed out that the government is gradually increasing the strict monitoring and control of toxic chemicals such as nitrogen oxides, ozone and VOC in the atmospheric environment and automobiles. On the day of the reporter's interview, Song said that he was participating in a meeting on air quality in the car carried out by relevant departments. “The Ministry of Environmental Protection has confirmed that it will begin to revise the existing “Guidelines for Air Quality Assessment in Passenger Vehicles†in 2014 and introduce mandatory standards for air quality in vehicles in 2015. Song Guangsheng told reporters in an interview.
Previously, some car companies and experts said that air pollution in the car is inevitable, because some chemical pollutants remain in the production process and materials, and these materials are often the necessary materials for automobile production. In this regard, Song Guangsheng told reporters that the pollution of toxic chemicals in the car is not uncontrollable. For example, in the automotive production process, the use of glue and lacquer processes can be reduced; in automotive interiors, non-polluting raw materials can be used. In other words, car companies can find alternative solutions without reducing the physical cost of the original materials, and finally supplement the external conditions such as ventilation and purification devices to achieve healthy and safe interior air quality.
Matting Agent For Coil Coatings
Description
1, Coated Aluminum Coil refers to the aluminum coil through coating and coloring treatment generally includes PE coated aluminum coil and PVDF coated aluminum coil. Coated aluminum coil is widely used to manufacture aluminum composite panel, aluminum ceiling, roofing aluminum veneer, aluminum honeycomb panel, electronic products, etc. Coated Aluminum Coil is the most popular new material currently. It is especially suitable for interior decoration and AD boards. It can be classified matt and glossy according to coating gloss.
2, Matting Agent specialized used for the matte Coil Coating. It provided high matting efficiency, excellent coating appearance and better transparency. As well as low oil absorption, easy dispersion and smoothly touch with minimal impact of viscosity.
Characters
|
1, Highest matting efficiency: High pore volume reach to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution. |
|
2, Surface smoothness and improvement in scratch resistance: These silicas have minimal effect on the physical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance. |
|
3, Good Transparency: Products high purity lead the refractive index inosculate with resin index. |
|
4, Good Dispersion: This series of products that can easily decentralized in any paint system, the average high-speed pulsator with 10-20 M/S of the line speed, after 10 minutes can be ok. |
|
5, Excellent Hand-feeling: These silicas have minimal effect on the mechanical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance. |
Application Fields
Coil Coating, Coating for aluminum Coil.
