How to test the performance of woven silicone tubing as the main component of a radiator?
Time:2022-06-06Page views:3420Previously, oil seals on cars were mostly made of nitrile rubber, but with the increase of vehicle speed and temperature, the lip of nitrile rubber is prone to cracking. After using high tear resistant silicone, the solution is satisfactory. Nitrile rubber is commonly used for oil seals in cars, but as the speed and temperature increase, the lip of nitrile rubber is prone to cracking. After using high tear resistant silicone, the problem was satisfactorily resolved. Silicone ignition wire has the advantages of resistance to corona discharge, ozone, fuel saving, non polluting environment, long service life, and reliable amine.Woven silicone tubingAs the main component of the radiator and heater, it has a long service life (5 years) and can travel at least 800000 kilometers.
Woven silicone tubing is resistant to high temperatures, corrosive water, and ozone, and has excellent electrical insulation properties, making it widely used in the industrial field. Due to its excellent heat resistance, it can also be used as a flexible joint for turbocharger air and oil return pipelines, where temperatures can reach up to 205 ° C, which ordinary organic rubber cannot withstand. Silicone products have been successfully applied in keyless door locks, electrical system protective covers, halogen lamps, lampshades, sunshades, etc., and will have more and more applications.
When purchasing, its performance should be tested to avoid difficulties in use. The performance of woven silicone tubing includes high temperature resistance, ductility, flame retardancy, etc.
We can take 1-2m and put it in a tunnel furnace at 120 ℃ for 45 minutes, then take it out to see if there are any adverse reactions such as bubbles or yellowing. If not, the high temperature resistance meets the requirements. When pulling and weaving silicone tubing with force, if there is no obvious deformation or elongation, and after bending back and forth for 3 times, if there are no cracks or wrinkles on the surface, it meets the tensile requirements. If ignited by an open flame and automatically extinguished after 5 seconds, it meets the flame retardant requirements.
