Why does the conveyor belt run longer after a long time? This is only related to the type of skeleton material used, that is, to the creep performance of the skeleton material. The running length of conveyor belt is caused by the following reasons, including fiber creep, fiber relaxation, and the reasons affecting fiber creep and relaxation.

So, what are the reasons for the conveyor belt running long and how to avoid it? Let's take a look with Xiaobian!

1. Fiber relaxation

Under constant tensile deformation, the internal stress (tension) of fiber or yarn will continue to decrease with time. This phenomenon is called "Relaxation".

In view of this, the conveyor belt shall be replaced regularly and maintained well.

2. Reasons affecting fiber creep and relaxation

The main reason for fiber creep and relaxation is the slip between macromolecules, so the factors affecting the force between macromolecules (such as warm clothing and humidity) will affect creep and relaxation. Many fibers are easy to creep and relax in high temperature and high humidity environment, so high temperature and high humidity are often used to eliminate internal stress. Especially cotton fiber. Moisture absorption will make the diameter thicker and the length longer. At the same time, moisture is similar to a plasticizer, which makes the fiber more prone to creep. However, the public moisture absorption rate of polyester is 0.3%, so no similar phenomenon will occur. Polyester has little relaxation during tensile deformation, so polyester has good resilience and wrinkle resistance, which can be analyzed from the comparison between polyester garment fabric and other fabrics.

For this, polyester should be the first choice for transporting skeleton materials. When the tensile rate is different, the tensile time is also different, the amount of slow elastic deformation is also different, and the tensile curve will be different. Therefore, the same tensile rate should be used when testing the skeleton material. The conveyor belt is mainly stored in a cool and ventilated place.

3. Fiber creep

Under the action of constant tensile force, the deformation of fiber and yarn is in proportion to the tensile force. But in fact, under the action of this constant tensile force, the deformation is not a constant, but a variable with time, which will continue to increase. Under the action of a certain tensile force, the deformation changes with time, which is called "creep". This is the root cause of the so-called "long run" of the conveyor belt.

The use time of the conveyor belt can be prolonged and the running length of the conveyor belt can be slowed down by special customization and adding tensile cloth layer.

The above is the introduction of "factors and solutions for the" long running "of conveyor belt". I believe you also have a certain understanding.
