Introduction to PVC and PU light conveyor belts and high-frequency welding technology of baffles

With the development of modern industry, conveyor belts play an increasingly important role in various fields. In order to meet the needs of different industries, various conveyor belts have been launched, including light conveyor belts made of PVC (polyvinyl chloride) and PU (polyurethane). This article will introduce the characteristics of PVC and PU conveyor belts and high-frequency welding process in detail.

1. PVC conveyor belt

1. Features
PVC conveyor belt is a light conveyor belt made of polyvinyl chloride as the main raw material, with good wear resistance, aging resistance, acid and alkali resistance and flame retardancy. In addition, PVC conveyor belt also has high tensile strength, impact resistance and tear resistance, and can work normally in various harsh environments.

2. Application range
PVC conveyor belt is widely used in the transportation process of food, medicine, chemical, electronics, tobacco and other industries. For example, in the food industry, PVC conveyor belts can be used to transport various food raw materials and finished products; in the pharmaceutical industry, PVC conveyor belts can be used to transport medicines and medical devices; in the chemical industry, PVC conveyor belts can be used to transport chemicals and dangerous goods; in the electronics industry, PVC conveyor belts can be used to transport electronic products and accessories; in the tobacco industry, PVC conveyor belts can be used to transport cigarettes and tobacco leaves.

2. PU conveyor belts

1. Features
PU conveyor belts are a kind of light conveyor belts made of polyurethane as the main raw material, with good wear resistance, oil resistance, solvent resistance and flame retardancy. Compared with PVC conveyor belts, PU conveyor belts have higher tensile strength, impact resistance and tear resistance, and can work normally in more severe environments. In addition, PU conveyor belts also have good air permeability and insulation, which are suitable for some occasions with special requirements for materials.

2. Application range
PU conveyor belts are also widely used in various industries, such as food, medicine, chemical industry, electronics, tobacco and other industries. Since PU conveyor belts have higher performance indicators, PU conveyor belts are often a better choice under certain special environments, such as high temperature, high humidity, strong acid and alkali conditions.

3. High-frequency welding process

The high-frequency welding process is a new type of hot-pressing composite technology. High-frequency current is used to generate heat inside two or more components, so that their molecules are melted and combined together. When making PVC and PU conveyor belts, the high-frequency welding process can achieve efficient connection of materials and improve the overall performance of the conveyor belt.

1. Principle
The principle of the high-frequency welding process is to use the heat generated by high-frequency current to melt the material locally, and then press the molten material into a whole through a pressure roller. In this process, the molecular structure between the materials is destroyed and reorganized, thereby achieving a strong bond.

2. Advantages

Improve the strength and wear resistance of the conveyor belt: The high-frequency welding process can make the baffle and conveyor belt of the conveyor belt more tightly connected, reducing the wear loss of materials during transportation.
Improve the sealing of the conveyor belt: The high-frequency welding process can effectively prevent the material from leaking from the interface and ensure the stability of the conveying process.
Improve the service life of conveyor belts: Since high-frequency welding can improve the overall performance of conveyor belts, their service life is also extended accordingly.

PVC and PU conveyor belts have become an indispensable and important part of modern industry due to their unique performance and wide range of applications. The high-frequency welding process provides an efficient and reliable connection method for the production of these conveyor belts, which helps to further improve the overall performance of conveyor belts.
