For more than and 10 years, the car has developed in the direction of reducing weight, increasing speed, saving fuel, limiting exhaust volume and improving reliability, and its core is to reduce the size of the engine. After the application of turbocharger, the engine under the hood is getting higher and higher, in 70s for 100 degrees, in 80s to 150 degrees Celsius, in 90s more than 200. Thus, the use of silicone rubber in the key parts of the growing number of.
The silicone rubber seals and gaskets have been widely used for driving shaft, block cover, water cooler, oil pan cover, headlights, sliding roof, sunroofs, muffler joint sealing, high and low temperature resistance, weather resistance and ventilation apparatus connector etc.; silicon rubber protective sleeve is mainly used for spark plug, distributor, ignition coil, plug the headlights, etc.; silicone rubber hose is mainly used for heating system, turbocharger etc.. In addition silicone rubber air bag fabric reinforced measures as anti-collision safety of drivers and passengers are also used for car.
In the past, the car with nitrile rubber seal manufacturing, but with the speed increase, the temperature rise increases, nitrile rubber lip easy cracking. After switching to high anti tear silicone rubber, the problem is solved satisfactorily. Silicon rubber ignition cable has the advantages of corona resistance, ozone resistance, fuel saving and no environmental pollution, long service life, safe and reliable; silicone rubber hose is used as heater radiator and main components, with long service life (5 years), at least at the speed of 800 thousand km. Due to the excellent heat resistance of silicone rubber hose, but also can be used as a turbocharger air pipe and oil return pipe of the flexible joint, where the temperature up to 205 degrees Celsius, the general organic rubber can not bear. Silicon rubber products in the non key door lock, electric system protection cover, lamp halogen lamp shade, shade, and other aspects of the application has been successful, and there will be more and more applications.
Many enterprises in China are put on the field of new energy vehicles throw hersesf efforts, but as the limitation of the core components of new energy vehicles, power battery of new energy vehicles, especially the new energy automotive battery thermal management solutions. Immediate water cooling, air cooling, phase change cooling, heat pipe cooling, a variety of specific programs to solve the battery heat conduction, although many thermal management schemes, but these are the flow of new energy automotive battery pack of soldiers, reasonable selection of raw materials is very important.
