Pu Roller

1. Composition of polyurethane roller

The polyurethane roller consists of two parts, the roller core and the polyurethane rubber coating. The roller core is usually made of aluminum alloy or steel, responsible for carrying the polyurethane rubber layer, and has the properties of pressure resistance, heat resistance and corrosion resistance. Polyurethane adhesive coating is a layer of adhesive layer formed by coating polyurethane material on the surface of the roller core. It has the characteristics of high strength, high elasticity, high wear resistance, chemical corrosion resistance, heat resistance, and antistatic.

2. The working principle of polyurethane roller

The working principle of polyurethane roller is mainly realized by the elasticity and wear resistance of polyurethane rubber layer. In the production process, polyurethane rollers are often used to withstand pressure, transmit power, coat or coat materials, etc. When the polyurethane roller is in contact with other materials, the polyurethane rubber layer on its surface can provide good friction and grip, so as to realize the smooth progress of various production processes.

3. Manufacturing process of polyurethane roller

The manufacturing process of polyurethane rollers requires high technical level and strict quality control, and generally includes the following steps: roller core processing, surface treatment, polyurethane rubber coating, grinding and testing. Among them, the processing of the roller core means that the manufacture of polyurethane rollers requires the processing and processing of aluminum alloy or steel materials to form the shape of the roller core. Next, surface treatment is carried out on the roller core so that the polyurethane glue can firmly adhere to the surface of the roller core. Then, polyurethane glue is coated on the surface of the roller core through a special process to form a flat and uniform glue layer. Grinding and testing are then carried out to ensure that the surface smoothness and dimensional accuracy of the polyurethane roller meet the requirements. The process requires a high level of technology and strict quality control to ensure that the performance and quality of polyurethane rollers meet the requirements.

In short, polyurethane roller is a roller made by coating polyurethane glue on the surface of the roller core. It has good wear resistance, chemical resistance and corrosion resistance, and can be widely used in printing, coating, textile, plastic, rubber and other industries. The manufacture of polyurethane rollers requires multiple complex processes, including roller core processing, surface treatment, glue coating, grinding and testing. A high level of technology and strict quality control are required in the manufacturing process to ensure that the performance and quality of polyurethane rollers meet the requirements.
