What is the Cause of the Aging of Conveyor Belts?

Jul. 14, 2020

During the whole process of using Conveyor Belts, there will be aging of the vulcanized rubber on the conveyor belt, which will cause the conveyor belt to aging. There are many reasons for the aging of the conveyor belt. Today, Rubber Belt Manufacturer will tell everyone.

1. Oxygen: Oxygen is reflected in the molecular structure of the vulcanized rubber in the vulcanized rubber to produce a mineral acid-based chain lock. The molecular structure chain is broken or excessively chemically cross-linked, resulting in changes in the characteristics of the vulcanized rubber. Chemical action is one of the key reasons for the aging of vulcanized rubber.

2. Activated oxygen: The organic chemical specificity of activated oxygen is much higher than that of oxygen, and it is more destructive. It also breaks the molecular structure chain, but the effect of activated oxygen on vulcanized rubber varies with the deformation of vulcanized rubber. As a vulcanized rubber used for deformation (mainly unsaturated fat vulcanized rubber), a crack perpendicular to the direction of in-situ stress appears, that is to say, "active oxygen cracking"; when used for deformation of vulcanized rubber, only the surface layer is converted into an air oxide Without cracking.

3. Heat: Raising the temperature can cause catalytic cracking or thermochemical crosslinking of the vulcanized rubber. But the basic effect of heat is still active. It improves the rate of oxygen external diffusion and active redox reaction, and then accelerates the rate of redox reaction of vulcanized rubber. It is a kind of aging condition of common phenomenon-thermal oxygen aging.

4. Light: The less microwaves, the greater the kinetic energy. It is ultraviolet light with high kinetic energy that can destroy the vulcanized rubber. In addition to ultraviolet light, the molecular structure chain of the vulcanized rubber can be immediately broken and chemically cross-linked. The vulcanized rubber causes mineral acid groups due to digestion and absorption of concentrated light to cause and accelerate the entire process of air oxidation chain reaction. Ultraviolet light plays the role of heating. Another characteristic of the light effect (unlike the heat effect) is that it is crucial to the surface of the oak. For specimens with a high glue content, cracks in the network structure will appear on both sides, which means that the "light surface cracks" are white.

Heat Resistant Conveyor Belts

Heat Resistant Conveyor Belts

We know that Heat Resistant Conveyor Belts machinery and equipment must pay attention to maintenance and maintenance in ordinary applications. Normal maintenance and maintenance is the most basic work in the whole process of machinery and equipment operation, not only to formulate normative rules and regulations, regular execution Quantitatively analyze the maintenance of machinery and equipment, and check the maintenance level and the total cost of maintenance raw materials, and regularly assess the progress of technical professional maintenance workers. Carrying out on-time maintenance and maintenance of the conveying machinery and equipment can prevent accidents before they happen, avoid big common faults, and endanger all normal production and manufacturing operations.
