Rubber products and the relationship between tensile stress and hardness. The ability to stretch and hardness are indicators of rubber products. Among them: the tensile stress and tensile deformation of rubber products, hardness and compression of rubber products related.
1. The relationship between the molecular structure of rubber products and the constant elongation stress:
Bucket elevator conveyor belt: rubber products, the larger the molecule, the greater the fixed elongation stress will be.
2. The relationship between the vulcanization system and the fixed elongation stress of rubber products:
With the increase of cross-linking density, the constant elongation stress will also increase.
Qingdao conveyor belt manufacturers suggest how to improve the fixed elongation capacity and hardness of rubber products:
1. Adding sulfur to ethylene propylene rubber will improve the fixed elongation capacity and hardness of rubber products.
2 in nitrile butadiene rubber with polyester, nitrile butadiene rubber and polyvinyl chloride mixture, can improve the rubber products Shore hardness.
