Scratches on double-pitch chains can increase the corrosion of the chain. What effect does the scratch on the double-pitch chain have on the use? Increasing the temperature can cause thermal cracking or thermal crosslinking of the rubber, increase the oxygen diffusion rate and activate the oxidation reaction, and the Jiangsu double-pitch chain accelerates the rubber oxidation reaction rate, thus Stainless steel chain plates constitute aging. The stainless steel chain plate under the repeated action of mechanical stress and the continuous friction process with the idler will cause the rubber molecular chain to break to form a free radical, trigger the oxidative chain reaction and form a force chemical process. In addition, it is easy to cause ozone cracking under stress.

      Because of the occurrence of scratches, the galvanized film is damaged, the protection effect on the chain is affected, and the chain is easily corroded, which affects the safety of operation. The appearance of scratches affects the use. If the scratches are severe, the chain will sound when it is in operation, and the situation of the chain may occur, which will affect the efficiency of the work.
