The volatilization hazard of automotive interior materials must be emphasized

After China joined the WTO, it officially opened the curtain of entering the first year of automobile consumption. Nowadays, China has surpassed the British to catch up with Japan, and its car ownership has become the second-largest in the world. However, automotive interior materials, some use a lot of rubber, plastics, adhesives and other substances, so that the content of volatile organic compounds in the car exceeded the standard.

These volatile organic compounds are harmful to the human body and can affect the health of the driver. For example, benzene, which can cause leukemia, comes from adhesives, artificial leather, lacquer, and leather. Formaldehyde is mainly derived from knitwear such as seat covers and door linings. These volatile organic compounds are not only harmful to human health but may also condense on the windshield or windows of the car, causing poor visibility and affecting the driver's line of sight and driving safety. Therefore, to properly control the production of volatile organic compounds, it is necessary to test the volatilization properties of automotive interior materials.

Experts in the field of automotive testing, a well-known third-party testing organization in the country, told the author that the atomization test of automotive interior materials can realize the control of volatile substances in these materials to effectively reduce the environmental pollution inside the vehicle. It has become an important means to control the quality of products for automotive and automotive interior materials manufacturers. At present, there are many international, domestic and enterprise standards for the fogging test of automotive interior materials. These standards involve three test methods, namely gloss method, gravimetric method, and haze method. The gloss method is: the gas evaporated by the sample in the mist cup is condensed on the low-temperature glass, and the fogging value of the sample can be obtained by comparing the gloss values ​​before and after the condensation of the glass; the gravimetric method Yes: the gas evaporated by the sample in the mist is condensed on the low-temperature aluminum foil, and the weight of the sample atomization-condensation can be obtained by weighing the weight of the aluminum foil before and after condensation; the haze method is: The gas evaporated by the sample in the mist cup is condensed on the low-temperature glass plate, and the haze value of the sample is obtained by comparing and calculating the haze value before and after condensation of the glass plate.

Experts in the test remind consumers: When purchasing a car, the air quality inside the car must be taken as an important purchase standard, and carefully selected for the car beauty decoration. Manufacturers of automotive and interior materials should use less or no materials containing volatile organic compounds to produce products, improve processes, actively seek environmentally friendly alternative materials, and use third-party testing agencies to send products for inspection to ensure that products meet relevant standards.

Which of the strangest car interiors in history have you seen?

Image
Compared to the auto interiors that look strange and even crazy, Xiao Bian thinks it's actually easier to make a striking car directly.  However, although the car  interior  is limited by space, vision and equipment, not to mention safety and cost, these do not prevent the car company from producing some strange car space and interiors.  From sensational color schemes to quirky decorative materials, here are some of the car manufacturers, favorite unusual and even crazy car interiors. 1. Lamborghini Miura Lamborghini Miura is not the first mid-engined car to go on the road, but when it was introduced in 1966, its interior and exterior design shocked the world.  Even if we can ignore the outer contour of the car's Bertone, we can't ignore its cockpit because it is almost completely in a prone position.  The car is like a racing car with almost no decoration, which makes Lamborghini's claimed maximum speed of 290 kilometers seem more credible.

How to disassemble the Kyre K50 battery, how to replace it？

Kairui k50 battery replacement disassembly installation method steps: first open the battery place, this time we will see a fixed bar on the battery above the buckle, use the 8th wrench to open. It's good to take it off after twisting it. The next step is the most crucial part. It will also involve security issues, so let's step through the steps to tell you the steps. Here we will see the icon marked with + pole and - pole next to the brick. We have to remove the positive pole first. Because the positive electrode touches the metal, it will reflect the most common is to spark, one will burn the contact, so remember to Be careful not to touch other metals in the process of removing the positive electrode. 　　Next, repeat the previous step to remove the negative electrode. The negative electrode does not reflect the metal. You can safely disassemble it, but try not to touch the metal and put the new battery on.  As the time of the removal, first fasten the fixing bar to t
