Vilka är applikationsområdena för silikonvärmare i bilindustrin?

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 print ink on paper to form two-dimensional flat drawings, while three-dimensional printers stack liquid photosensitive resin materials, molten plastic wires, gypsum powder and other materials by spraying binders or extrusion to form three-dimensional entities. After the application of turbochargers, the operating temperature under the hood has become higher and higher, from 100℃C in the 1970s to 150℃C in the 1980s, and then to more than 200 grader C på 1990 -talet . Därför ökar användningen av silikongummi i nyckeldelar.

För närvarande har silikonteggummitätningar och packningar använts i stor utsträckning i drivaxlar, inbäddade täcken, oljepannor, svalare vattenskydd, strålkastare, glidande soltak, öppna tak, ljudtätningar med höga och lågtemperaturer, väderbeständiga kontakter och ventilatorer osv. Spolar, pluggar, strålkastare osv. . Silikongummislangar används huvudsakligen för värmesystem, turboladdare, etc.

Tidigare var oljetätningar på bilar mestadels gjorda av nitrilgummi, men eftersom den ekonomiska hastigheten kan ökas och temperaturökningen ökar, är nitrilgummiläppen benägen att spricka . efter att ha bytt till hög-bränsle-gummi, problemet var tillfredsställande löst . silikon gummi 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 ., och det kommer att finnas fler och fler applikationer .
