How to prevent cracks in conveyor belts

Jun. 13, 2022

Under realistic conditions, the conveyor belt can be flat sulfur (chemical symbol: S) chemistry NN with EP fabric core conveyor belt. Rubber conveyor belt storage and transportation conditions: In storage and transportation, isolate the source of fire, avoid contact with sharp objects and chemicals with greater corrosiveness, and avoid long-term storage in the sun. Smoothness can be avoided by narrowing the belt core, keeping the pads away from the belt edge and leaving space for the core to extend its width. The relationship between them is: distance between the pads > semi-finished belt width > core width. A suitable narrowing factor for the core layer should consider the lateral width of the core and estimate the shrinkage in the width direction after sulfurization, so that the standard width of the finished product is reasonable.

How to prevent the belt from cracking

(1) Fabric skeleton performance is the fundamental to determine the performance of the belt. Rubber conveyor belt has the characteristics of heat-resistant belt, wear-resistant belt, burn-resistant belt, oil-resistant belt, alkali-resistant belt, alkali-resistant belt, heat-resistant belt, cold-resistant belt, etc. It is mainly used for solid material conveying in various mines, metallurgy, steel, coal, hydropower, building materials, chemical industry, grain and other enterprises. At present, NN and EP fabrics with weft weaving shrinkage elongation is too large is the root cause of the smooth pattern. Reduce (reduce) the weft elongation that is to improve the performance of the belt is also an effective way to reduce (reduce) the cost.

(2) Narrowing the core of the strip during the forming of the billets can avoid the generation of the smoothing.

(3) The related factors that cause the generation of smoothness cannot be ignored. Rubber conveyor belts have the characteristics of heat-resistant belt, wear-resistant belt, burn-resistant belt, oil-resistant belt, alkali-resistant belt, alkali-resistant belt, heat-resistant belt, cold-resistant belt and so on. It is mainly used for solid material conveying in various mines, metallurgy, steel, coal, hydropower, building materials, chemical industry, grain and other enterprises.

(4)The thermal shrinkage of the fabric is not the cause of (cause) the appearance of smooth grain, it is just a general characteristic of chemical fiber fabric.

During the long time operation of the conveyor belt, due to air corrosion or material impact and other reasons, more or less surface ulceration, defects, cracking and other phenomena will occur. Timely repair can not only control the cost to a minimum state, but also effectively reduce the safety risks, so how to repair the surface of the conveyor belt after a long time, such as ulcers, defects and cracks?

In order not to delay the production and not to affect the physical transportation, it is undoubtedly important to complete the conveyor belt repair as fast as possible. It is a good choice to use rubber repairing agent for quick repair on site.

Cold vulcanized rubber repair agent is a new type of belt repair material, the product is generally two-component or multi-component, mixed and stirred in a paste, can be applied at any angle, easy to control and operate, without worrying about the occurrence of self-flow phenomenon.

Liquid rubber cold vulcanized rubber repair agent, supporting the cleaning agent for the belt surface cleaning treatment and transition treatment of the primer, the use of the belt surface performance to a greater extent to optimize the treatment.
