Rubber seals are often used for sealing, but sometimes it is also used in other aspects, when we use the seal ring will encounter various problems, such as fracture, in fact, there are three reasons for fracture.
Overload: Each material and product has its own load, so rubber materials are no exception. For example, the rated load that the rubber ring can withstand is 10N, and the working environment is 20N, and it is easy to break under such overload. Therefore, when selecting such parts, it is necessary to consult the relevant data to understand how heavy the load is and whether the product is operating under overload conditions. Generally speaking, no more than 90% of the product load is relatively stable.
Aging of rubber sealing ring material: aging of material is also an important reason for fracture, in many cases, each material has its own life, if the use of a long time, more than their own life, it will be damaged, manifested as fracture; All products become brittle as they age, and then stress is concentrated on the notch, leading to fracture. Therefore, the rubber ring on the mechanical product needs to be replaced in time before aging and breaking to avoid the impact of cracking.
The rubber seal is corroded: It is easy to understand when the product breaks after corrosion. For example, in an environment with chemical corrosion, if the inappropriate material is used, the fracture will occur, and the process is very fast. Therefore, when selecting materials for products, it is necessary to understand the material characteristics and environmental media. Only when the material matches the medium used can the product play its normal role.
