A conveyor belt for turning machines is a type of mechanical device that transports materials in a continuous manner through driven movement; the goods it is commonly used for are made from thin sheets and steel strips. Combining performance, appearance, and operational features, it is widely employed in industry for the automated transportation, distribution, and sequential packaging processes in sectors such as food, canned goods, pharmaceuticals, beverages, cosmetics and cleaning products, paper products, seasonings, and the dairy industry. After using it for a period of time, it will be noticed that the belt of the turning machine becomes passivated. What causes this? The manufacturers of turning machine belts will explain it as follows: 1. The nickel content in the belt – the corrosion resistance of stainless steel belts is greatly influenced by the nickel content in the stainless steel; a lower nickel content results in weaker passivation properties. 2. Environmental factors – the passivation layer on stainless steel belts has a semi-stable structure, and its passivation can be suppressed thermodynamically in order to protect the belt. During use, it should be cleaned regularly to remove any deposits on its surface and eliminate harmful substances. 3. Surface lubricity: the lower the roughness of the surface of the stainless steel mesh belt, the smoother the surface will be, making it more difficult for foreign objects to adhere to it, as well as reducing the rate of corrosion in that area. Therefore, the surface of stainless steel mesh belts should be kept as lubricated as possible. 4. Chloride ions cause significant damage to stainless steel mesh belts; during the passivation process, it is necessary to strictly control the concentration of chloride ions in the passivation solution, and using chemical materials for passivation can help to regulate the level of chloride ions effectively. The above are the reasons for the passivation of conveyor belts used in turning machines, as explained by the manufacturers of such belts.
