After the rubber pipe has been used for a long time, it will also cause aging. Among them, there are many factors that affect the service life of rubber pipes, such as uneven stress, problems with rubber formulations, and vulcanization processes. Adhesion cracking in key parts will also inevitably greatly shorten the fatigue life of rubber joints . In order to extend the overall service life, it is not only necessary to reinforce from the outside, to strengthen the use characteristics of the rubber joints , but also to clean the bacteria inside. The use of rubber will cause harm. Our rubber flexible joints will be sterilized before leaving the factory to eliminate microorganisms, bacteria and so on. There are many kinds of sterilization methods. Generally, γ-rays (mainly produced by the isotope cobalt 60) are used for effective sterilization. The advantage is that it can be performed at room temperature without affecting any other substances in the soft rubber joint . After γ-rays irradiate rubber for a long time, rubber molecules will be very strongly affected, with two consequences. One: the broken chain loses its elasticity and becomes hard and brittle. The second is to generate macromolecule free radicals and combine with each other to increase the overall crosslinking density. After being irradiated by γ, these two conditions will exist at the same time. In constant observation, we found that under the condition of 0-200kGy γ-ray, we observed the performance of fluoro rubber and nitrile rubber, and found that their hardness and stress were obvious Increase in elongation at break decreases. From this point of view, the fluororubber and nitrile rubber tested are mainly based on the above-mentioned second cross-linking situation as a whole. Therefore, the increase in cross-linking density may result in phenomena like the fluorine rubber and nitrile rubber.
Xinli Pipeline Equipment Co., Ltd. specializes in the production of rubber hoses, rubber joints , rubber flexible connections and other pipeline equipment. In the use of rubber pipe fittings, in order to extend its service life, our technicians will sterilize before leaving the factory.
