Scratches on the double-pitch chain will increase the corrosion of the chain

The appearance of scratches on double-pitch chains can increase the corrosion of the chains. What are the effects of scratches on double-pitch chains their use? Increasing the temperature can cause thermal cracking or thermal cross-linking of rubber, increase the diffusion rate of oxygen and activate the oxidation reaction, thus the oxidation reaction rate of rubber, and thus causing the aging of stainless steel chain plates. In the process of repeated mechanical stress and continuous friction with the idler, the rubber molecular chain will break and generate free radicals, initiating an oxidative chain reaction and forming a mechanochemical process. In addition, ozone cracking is easily under the action of stress.

The occurrence of scratches causes damage to the galvanized film, affecting the protective effect on the chain, making the chain prone to corrosion, and operational safety. The appearance of scratches affects the use; if the scratches are severe, they can cause noise during chain operation, possibly leading to chain jamming, affecting work efficiency.
