Because of its superior elasticity and compression properties, rubber seals seals can effectively prevent medium leakage and are widely used in the field of sealing; it is precisely because of the wide application of rubber seals that the three main reasons for the failure of rubber seals seals Superior elasticity and compression properties can effectively prevent medium leakage, and are widely used in the field of sealing; it is precisely because of the wide application of rubber seals that its application occasions and application environments are diverse and uncertain. These are all important reasons for the frequent failure of rubber seals. Fracture is an important phenomenon, which accounts for more than 80% of defects. What is the reason for the rupture of rubber seals seals? 1. The fracture of the product after corrosion is easy to understand. For example, the material of the silicone seal is not resistant to oil. How to place the silicone seal in an oily environment for a long time is easy to be corroded and broken; in addition, in a chemically corrosive environment, if Without the use of fluororubber seals, it is easy to break, and only fluororubber seals have corrosion resistance. Therefore, when selecting product materials, it is necessary to understand material properties and environmental media. Only when the material and medium are matched can the product play its best role. 2. Material aging: In most cases, material aging is also an important cause of fracture. Every substance has its own life. If it is used for a long time, it will break when it exceeds its lifespan. After aging, the product will become hard and brittle, and stress concentration will occur at the gap, resulting in fracture. Therefore, the rubber seals on mechanical products need to be re-aged and replaced before breaking, so as to avoid safety accidents caused by the breaking of the rubber ring. 3. Overload: Every material and product has its own safe load, and rubber seals are no exception. For example, the rated load of the rubber ring is 10N, and the working environment is 20N. Under such overload, it is easy to break. Therefore, it is necessary to refer to the relevant information to see how big the load of the product is? Is the product overloaded? Generally speaking, it is safer to not exceed 90% of the product load.
