Because the joint strength is low, so when bonding method is not correct, the joint strength will be lower, in the surgery, or if a layer of cloth, or is not excessive, lap length, grinding step number is not enough, rubber joints with rubber performance is not good and wire rope polished excessive, has since sulfur failure, wire rope rust, joint strength will be reduced to very low, so, in the process of using, joints are especially easy to fracture. 

    1, if the pressure is too high, the application limit bolt flange connected together at both ends. 
    2, such as overhead can be equipped with elastic support, the installation bolts to be tightened with diagonal method. 
    3, the material application of the polar rubber, good sealing performance, light weight, convenient installation and repair, long service life, but to avoid contact with sharp metal instruments, lest punctured sphere. 
    4, different materials can be made according to acid and alkali resistance, corrosion resistance, oil resistance, heat resistance and other varieties, to adapt to a variety of media and the environment. 
 

    Rubber joint at the joint of the conveyer belt when work intensity is much lower than normal with strength. Mechanical connection, the joint strength can only be achieved with the strength of fifty-one percent, but if the cold glue quality compared with HERSHEY'S, the joint strength can reach about seventy percent, if it is a joint method is correct, no quality defects, the strength of hot glue joints can reach about ninety percent.
