Why Does Nylon Conveyor Belt Age?

Jan. 29, 2021

As a Nylon Conveyor Belt Factory, share with you.

In the entire process of nylon conveyor belt application, it is very easy to cause the vulcanized rubber layer to age and fall. After scientific research, the factors that cause vulcanized rubber to age are as follows:

1) Oxygen: Oxygen reacts through the molecular structure of the vulcanized rubber in the vulcanized rubber to produce a dispersive base chain reaction, and the molecular structure chain is broken or excessively chemically cross-linked, resulting in a change in the characteristics of the vulcanized rubber. Chemical action is one of the key reasons for the aging of vulcanized rubber.

2) The organic chemical specificity of active oxygen and active oxygen is much higher than that of oxygen, and it is more destructive. It also breaks the molecular structure chain, but the effect of active oxygen on vulcanized rubber varies with the deformation of vulcanized rubber. When used as a deformed vulcanized rubber (mainly unsaturated fat vulcanized rubber), cracks appear perpendicular to the direction of the ground stress function, that is, "active oxygen cracking"; when used for deformed vulcanized rubber, only the surface layer forms an air oxide film. Does not crack.

3) Heat: Increasing temperature can cause catalytic cracking or thermochemical cross-linking of vulcanized rubber. But the basic function of heat is still active. Increasing the oxygen diffusion rate and active redox reaction, and then accelerating the redox reaction rate of vulcanized rubber, it is a common phenomenon of aging-thermal oxygen aging.

4) Light: The less light waves, the greater the kinetic energy. What destroys vulcanized rubber is ultraviolet light with higher kinetic energy. In addition to ultraviolet light that can immediately cause the rupture and chemical cross-linking of the molecular structure of the vulcanized rubber, the vulcanized rubber will digest and absorb solar energy and create a dispersed base, which causes and accelerates the entire process of the air oxidation chain reaction. Ultraviolet light plays a role in heating. Another characteristic of light function (not the same as heat function) is that its key is to grow on the surface of the rubber. For the specimens with high glue content, there will be reticular structure cracks on both sides, that is to say, "light surface cracking".

5) Ground stress of mechanical equipment: The conveyor belt will melt the molecular structure of vulcanized rubber to form a dispersed base under the continuous effect of the ground stress of the mechanical equipment and the continuous friction with the buffer roller, which will cause the air oxidation chain reaction to produce organic strength. The whole process of chemistry. Mechanical equipment breaks the molecular structure chain and the whole process of active air oxidation of mechanical equipment. Which one has the upper hand depends on the standard. In addition, it is very easy to cause active oxygen cracking under the effect of ground stress.
