Wat zijn de toepassingsgebieden van siliconenverwarmers in de auto -industrie?

For more than ten years, automobiles have been developing in the direction of reducing weight, increasing speed, saving fuel, limiting emissions and improving reliability, with the core being to reduce the size of the engine. Silicone rubber heaters are mainly composed of nickel-chromium alloy heating wires and silicone rubber high-temperature insulation layers. The silicone rubber high-temperature insulation layer is a thin sheet (standard thickness is 1.5mm) made of silicone rubber and glass fiber cloth. The silicone rubber heater has good softness. Silicone rubber heating belt is a particularly soft heating belt composed of nickel-chromium alloy wire and insulating material. It has high design power density, fast heating, high thermal efficiency and long service life. In addition to being used for heating and heat preservation of general constant power belts, it can also be used in places that need heating in some cases. 3D printer heating sheets use layer-by-layer stacking to produce three-dimensional models. Its operation process is similar to that of traditional printers, except that traditional printers Druk inkt op papier om tweedimensionale platte tekeningen te vormen, terwijl driedimensionale printers vloeibare fotosensitieve harsmaterialen, gesmolten plastic draden, gipspoeder en andere materialen en andere materialen doorbakken of extrusie om driedimensionale entiteiten te spuiten, is de operatietemperatuur onder de hap geëindigd, van 100 graden C in de 1970, van de 1970 van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970, van de 1970 van de 1970, van de 70 graden C in de 1970. 1980s, en vervolgens tot meer dan 200 graden C in de jaren 1990 . Daarom neemt het gebruik van siliconenrubber in belangrijke delen toe.

At present, silicone rubber seals and gaskets have been widely used in drive shafts, embedded covers, oil pans, cooler water covers, headlights, sliding sunroofs, open roofs, muffler joint seals, high and low temperature resistant, weather-resistant connectors and ventilators, etc. Silicone rubber protective sleeves are mainly used for spark plugs, distributors, ignition Spoelen, pluggen, koplampen, enz. . siliconenrubberslangen worden voornamelijk gebruikt voor verwarmingssystemen, turboladers, enz. . Bovendien zijn stoffen versterkte siliconenrubber-airbags gebruikt in auto's als anti-collision veiligheidsmaatregelen voor stuurprogramma

In het verleden werden oliafdichtingen op auto's voornamelijk gemaakt van nitrilrubber, maar naarmate de economische snelheid kan worden verhoogd en de temperatuurstijging toeneemt, is de nitrilrubberlip gevoelig voor kraken . Nadat het schakel naar siliconenweerstand met een hoog-tereilen, is het probleem opgelost. pollution to the ecological environment. They have long service life and are safe and reliable. Silicone rubber hoses are used as the main functional components of radiators and heaters. They have a long service life (5 years) and can travel at least 800,000 km. Due to the excellent heat resistance of silicone rubber hoses, they can also be directly used as flexible connecting joints for the air pressure pipes and return oil pipes inside the turbocharger. The temperature here has reached 205℃, which general technical synthetic rubber companies cannot bear. Silicone rubber products have achieved great success in keyless door locks, electrical information system protection covers, headlight halogen lamp covers, awnings, etc ., en er zullen steeds meer toepassingen . zijn
