What are the reasons for the aging problem of stainless steel mesh belt

Stainless steel mesh belts must take the road of technological innovation and development. Our stainless steel mesh belt manufacturers only need to increase their technical contributions, change their development thinking and structural industry innovation. An effective method must be based on the characteristics of the product to make some improvements. For problems in use, find solutions. The good situation is to solve them. If it cannot be solved completely, it should be avoided according to the actual situation. So what are the factors that cause the aging of the stainless steel mesh belt?






1. Oxygen: Oxygen reacts with the rubber molecules in the rubber by a free radical chain reaction, and the molecular chains of the stainless steel mesh belt are broken or excessively cross-linked, resulting in changes in the properties of the rubber. rubber. Oxidation is one of the important causes of rubber aging.

2. The chemical activity of ozone and ozone is much higher than that of oxygen, and it is more destructive. It will also break the molecular chain of the stainless steel mesh belt, but the impact of ozone on rubber depends on whether the rubber is deformed. When used as deformed rubber (mainly unsaturated rubber), cracks perpendicular to the direction of stress will appear, so-called "ozone cracks." When used as a rubber for deformation, only an oxide film is formed on the surface without cracking.

3. Heat: An increase in temperature will cause thermal cracking or thermal crosslinking of the rubber. But the basic function of heat is activation. Increase the diffusion rate of oxygen and activate the oxidation reaction, thereby accelerating the rate of the rubber oxidation reaction, which is a common oxygen-thermal aging phenomenon.

4. Mechanical stress: The stainless steel mesh belt will destroy the rubber molecular chain under the repeated action of mechanical stress and the continuous friction process with the idler, thereby generating free radicals, thereby triggering chain oxidation and oxidation reactions. It will form a mechanochemical process. Mechanical rupture of molecular chains and mechanical activation of oxidation processes. Which can have an advantage depends on the conditions. In addition, it is easy to cause ozone burst under pressure.
