The elasticity of rubber gaskets refers to their ability to deform when subjected to pressure and return to their original state after the pressure has disappeared. This elasticity mainly depends on the production material and process of rubber gaskets. Under normal circumstances, natural rubber, styrene butadiene rubber and silicone rubber are the main materials for making rubber gaskets. These materials have excellent elasticity and insulation properties and are widely used in various occasions.
However, the rubber washer will gradually lose its elasticity during long-term use, affecting its sealing performance and the normal operation of the equipment. At this time, we need to take timely measures to restore its resilience.
To restore the elasticity of rubber gaskets, the following methods can be taken:
1. Chemical treatment
Chemical treatment is a method of changing the internal structure of the rubber gasket through a chemical reaction, so as to restore its elasticity. The rubber washer is placed in a solution containing oxidant and reducing agent, and its internal structure is changed through REDOX reaction, so as to achieve the purpose of restoring elasticity. The advantage of this method is that the effect is significant, but it may affect the color and other properties of the rubber gasket.
2. Physical vibration method
Physical vibration method is a method to change the internal structure of rubber gasket by using vibration energy. The rubber washer is placed on the vibration table, and its internal structure is changed by vibration of a certain frequency and amplitude, so as to restore its elasticity. The advantage of this method is that it is simple to operate and does not change the color and other properties of the rubber gasket.
In practical application, we need to choose the appropriate recovery method according to the specific scenario. For example, for heavy duty occasions such as automobiles and machines, rubber gaskets with higher strength and better pressure resistance can be selected; For high-precision occasions such as electronic equipment, rubber gaskets with higher hardness and smaller deformation can be used. At the same time, in the selection process of rubber gaskets, it is also necessary to consider its color, transparency, chemical corrosion resistance and other factors.
In short, restoring the elasticity of rubber gaskets is one of the important measures to ensure the normal operation of equipment. Through reasonable selection of methods and materials, the performance and life of rubber gaskets can be improved, and the maintenance cost can be reduced.
