How to test the performance of braided silicone hose as the main component of radiator?时间：2022-06-06浏览次数：1322
In the past, most oil seals on cars used nitrile rubber, but with the increase of speed and temperature, the lip of nitrile rubber is easy to crack. After using high tear resistant silicone, the solution is satisfactory. Most oil seals on cars use nitrile rubber, but with the increase of speed and temperature, the lip of nitrile rubber is easy to crack. After using high tear resistant silica gel, the problem was satisfactorily solved. Silicone ignition wire has the advantages of corona resistance, ozone resistance, fuel saving, no environmental pollution, long service life, reliable amine, etc.Braided silicone hoseAs the main component of radiator and heater, it has a long service life (5 years) and can travel at least 800000 kilometers.
Braided silicone hose is resistant to high temperature, corrosive water and ozone. It has good electrical insulation and is widely used in industrial fields. Due to its excellent heat resistance, it can also be used as a flexible joint of turbocharger air pipeline and oil return pipeline. The temperature in these places is as high as 205 ° C, which is unbearable for ordinary organic rubber. Silicone products have been successfully used in keyless door locks, electrical system protective covers, halogen lamps, lampshades, sunshades, etc., and will be used more and more.
At the time of purchase, its performance should be tested to avoid difficulties in use. The properties of braided silicone hose include high temperature resistance, ductility, flame retardancy, etc.
We can put 1-2m into a 120 ℃ tunnel furnace for 45 minutes, and then take it out to see if there are bubbles, yellowing and other adverse reactions. If not, the high temperature resistance meets the requirements. When the braided silicone hose is pulled by force, there is no obvious deformation or elongation. If there is no crack or fold on the surface after bending back and forth for 3 times, it meets the tensile requirements. If it is ignited by an open fire and automatically extinguished 5 seconds after leaving the fire, it meets the flame retardant requirements.
