The tensile properties of rubber expansion joints refer to their performance under tensile stress; resilience refers to their ability to return to their original shape after the tensile stress is removed. Rubber expansion joints with poor resilience are prone to deformation after repeated stretching, leading to a shortened service life.
Rubber expansion joints should maintain good sealing performance under tension; they are prone to softening and deformation at high temperatures and hardening and cracking at low temperatures, affecting their performance and service life.
During use, they come into contact with various chemical substances, therefore, they need to possess a certain degree of corrosion resistance. Standards require that after chemical immersion tests, the surface of rubber expansion joints should show no bubbles, cracks, or peeling, and their physical properties should not significantly decrease.
They are also affected by environmental factors and gradually age, therefore, they need to possess a certain degree of aging resistance. Standards require that after aging tests, there should be no significant change in appearance, and their physical properties should not significantly decrease.
Therefore, rubber expansion joints should be inspected regularly, including for appearance, wear, and displacement, and kept clean to prevent corrosion from dust, dirt, and other substances.
Note the usage cycle: The replacement cycle of rubber expansion joints should be determined according to the actual situation to ensure their performance and stability.
