Lightweight conveyor belt materials and processing methods

I. Materials

Lightweight conveyor belts are made from a variety of materials, commonly including PVC (polyvinyl chloride), PU (polyurethane), rubber, and silicone. Different materials offer different properties and are suitable for various applications.

1. PVC Conveyor Belts: PVC conveyor belts offer excellent wear resistance, corrosion resistance, tensile strength, and flame retardancy. They are moderately priced and widely used in general material conveying applications.

2. PU Conveyor Belts: PU conveyor belts offer excellent wear resistance, oil resistance, chemical corrosion resistance, and tear resistance. They have good elasticity and are suitable for conveying materials requiring a high coefficient of friction.

3. Rubber Conveyor Belts: Rubber conveyor belts offer good wear resistance, high-temperature resistance, and corrosion resistance. They have high tensile strength and are suitable for conveying heavy materials and in high-temperature environments.

4. Silicone Conveyor Belts: Silicone conveyor belts offer excellent high-temperature resistance, corrosion resistance, and insulation. They are highly flexible and suitable for conveying materials requiring high precision.

II. Processing Methods and Techniques

The processing methods and techniques for light-duty conveyor belts mainly include the following steps:

1. Raw Material Selection and Batching: Based on the usage requirements of the light-duty conveyor belt, select suitable raw materials for batching, such as PVC, PU, ​​and rubber.

2. Mixing and Calendering: Mix the batched raw materials to ensure uniform mixing. Then, calender the mixed rubber compound into a sheet of a certain thickness using a calender.

3. Molding and Vulcanization: Cut and shape the calendered rubber sheet according to the dimensions and shape of the light-duty conveyor belt. Then, place the shaped conveyor belt in a vulcanizing tank for vulcanization treatment to give it a certain strength and elasticity.

4. Surface Treatment and Processing: Perform surface treatments on the light-duty conveyor belt as needed, such as grinding, printing, and labeling. Special processing can also be performed, such as drilling, grooving, and adding baffles.

5. Quality Inspection and Packaging: Conduct quality inspections on the finished light-duty conveyor belt to ensure it meets relevant standards. Then, package it for transportation and storage.
