The best experience of driving not only comes from flexible maneuvering, soft seats and extreme quietness, but an oasis in the car is also the key to a good mood.

Provide a healthy environment for the elderly and children, so that family and friends can smell the green mountains, green waters and white clouds from the air quality. Use the ecological purification cabin as a mobile fortress against smog

Multi-dimensional improvement of air quality in the car

With the continuous escalation of automotive consumer demand, in addition to many requirements in terms of vehicle performance configuration, consumers are also very concerned about safety, comfort, and driving environment. The control of the air quality in the car is also one of the important reference indicators for consumers to purchase models. Therefore, many brands and models have invested considerable research and development in this area. The advanced purification device in the car and the large-scale use of environmentally friendly materials in the interior Wait, when it comes to these editors, such a term will pop up in their minds-ecological purification cabin.

Speaking of the concept of ecological clean cabin, it comes from the G-BLUE healthy ecological technology module of Geely's iNTEC technology brand. Previously, the "iNTEC Laboratory" column also introduced the AQS (Air Quality Control System) in this module. AQS can not only sense the air conditions inside and outside the car, but also select the appropriate air circulation method to prevent polluted air from entering the cabin. At the same time, high-efficiency precision filtration technologies such as activated carbon filter material strong adsorption technology, anion generator sterilization and deodorization, through adsorption, decomposition and other methods, effectively remove PM2.5 particles, formaldehyde, benzene and other harmful gases in the air in the car. Pathogenic microorganisms quickly refresh the air in the car. However, are these just enough to control the air quality in the car? From the perspective of the research and development process of Geely models, it is obviously more than that. Then the laboratory of this issue will bring Geely automotive non-metallic materials VOC testing tests, aiming to show everyone how to "fundamentally" improve the air in the car from another dimension. quality.

Relevant investigations and studies have shown that a large part of the culprit of car interior environment and air quality pollution comes from the volatile organic pollutants generated by the volatilization of car interior materials. Therefore, how to get rid of harmful substances in the air can be regarded as a "temporary cure", and the selection of interior materials is to fundamentally control volatile organic pollutants within health standards.

"Selection Knowledge" of Interior Materials at High Temperatures

Treat both symptoms and root causes. Under the premise of an efficient AQS system, Geely models actively select high-quality materials and cleaning techniques during the development process. In the selection of vehicle interior materials such as car paint, seat materials, side panel interior materials, and carpet materials , Using low-volatility environmentally friendly materials, also adopting environmentally friendly design in the manufacturing process, using a large number of snap-on lap schemes and ultrasonic welding schemes, reducing the use of adhesives in the car, thereby reducing the volatile organic compounds generated by interior materials Pollutants.

The above-mentioned non-metallic material VOC detection test is the main method to identify and select qualified interior materials. As you can see from the video, the engineer will first do a pre-treatment of the experiment, take samples of the interior materials and place them in a plastic bag dedicated to the experiment, and repeatedly evacuate the bag through the equipment twice, and then fill it with nitrogen to ensure There is only clean nitrogen in the bag, avoid mixing other gases to affect the test data.

Then put the processed test sample into the 24 cubic meter VOC environmental chamber in the video, and connect the hose that can extract gas from the outside. Then turn on the equipment, set the time and temperature, and bake the test samples at a high temperature, so that organic pollutants are volatilized and released in the plastic bag containing the interior sample materials. To give an image example, if you park your car outdoors in summer, expose it to the scorching sun for a long time, and then open the closed door, you will smell the special smell of soft plastic materials or leather products. I believe many old drivers have a deep understanding.
