Will the Automotive Wiring Harness Protection Sleeve be deformed and aged after high temperature sterilization?
July 04, 2023
Under normal circumstances, we all know that the Automotive Wiring Harness Protection Sleeve will only cause aging if it is used improperly. If the Automotive Wiring Harness Protection Sleeve is sterilized by high temperature, will it also be deformed and aged? Or is the Automotive Wiring Harness Protection Sleeve only in ozone and The environment with moisture will only age. The following editor will take a look at the reasons that cause the deformation and aging of the Automotive Wiring Harness Protection Sleeve.
1. The role of ozone
Ozone has high chemical active oxygen and is more destructive. It also breaks the molecular chain, but the effect of ozone on the Automotive Wiring Harness Protection Sleeve varies with whether the Automotive Wiring Harness Protection Sleeve is deformed or not. When used on deformed Automotive Wiring Harness Protection Sleeve (mainly unsaturated
Cable Sleeve), cracks appear in the direction of the stress, which are so-called "ozone cracks"; when applied to deformed Automotive Wiring Harness Protection Sleeve, only the surface generates oxidation film without cracking.
2. The role of moisture
The Automotive Wiring Harness Protection Sleeve is easily damaged when it is exposed to rain in humid air or soaked in water. This is because the water-soluble substances and clear water components in the Automotive Wiring Harness Protection Sleeve are extracted and dissolved by water. Caused by hydrolysis or absorption. Especially under the alternating action of water immersion and atmospheric exposure, it will accelerate the damage of the Automotive Wiring Harness Protection Sleeve. However, under certain circumstances, moisture does not damage the protective cover of the Automotive Wiring Harness Protection Sleeve, and even has the effect of delaying aging.
3. Oxidation
Oxygen in the Cable Sleeve reacts with free radicals in the Cable Sleeve molecules, and the molecular chains are broken or over-crosslinked, causing changes in the performance of the Cable Sleeve. Oxidation is one of the important reasons for the aging of Cable Sleeve.
It can be seen from this that the reasons for the aging of the Automotive Wiring Harness Protection Sleeve are nothing more than the above three points. There will be no high temperature sterilization that will cause the deformation and aging of the Automotive Wiring Harness Protection Sleeve, because the Automotive Wiring Harness Protection Sleeve is resistant to cold and high temperature, stable chemical substances, and can be used for a long time. It works above 150°C and above 300°C for a short time, so there is no need to worry about the deformation and aging of the Automotive Wiring Harness Protection Sleeve after high temperature sterilization.
