The structure of polyurethane coated roller

Polyurethane coated roller usually includes three parts: roller core, rubber layer and surface treatment. The roll core is the body of the polyurethane coated roller, usually made of metal or plastic. The rubber layer is an important part of the rubber roll, which is usually made of elastic materials such as rubber or polyurethane. The surface treatment layer is the outer layer of the polyurethane coated roller, which is usually made of a material with higher hardness, such as hard rubber or polyurethane.

Manufacturing process of polyurethane coated rolls usually includes the following steps:

1. Roller core manufacturing: The roller core is usually made of metal or plastic, and its diameter and length are determined according to the specific application needs.

2. Adhesive layer manufacturing: Adhesive layer is usually made of elastic materials such as rubber or polyurethane, and its hardness and thickness are determined according to the specific application needs. Rubber layer manufacturing usually includes mixing, extrusion, vulcanization and other processes.

3. Surface treatment: The surface treatment layer is usually made of materials with higher hardness, such as hard rubber or polyurethane. Surface treatment usually includes grinding, polishing and other processes.

Application of polyurethane rubber roller

The application of polyurethane coated roller is very wide, mainly used in the following areas:

1. Printing: polyurethane coated roller is an important part of the printing press, they can be used to print various materials, such as paper, plastic film, metal foil and so on.

2. Coating: can be used for a variety of coating processes, such as coating glue, coating paint, coating paint, etc.

3. Gluing: It can be used for various gluing processes, such as gluing paper, gluing cloth, etc.

4. Embossing: can be used for a variety of embossing processes, such as embossing paper, embossing cloth, etc.

Development prospect of polyurethane coated roller

With the continuous progress of science and technology, the application field of polyurethane coated roller is also expanding. In the future, the development prospects of polyurethane coated roller are very broad, mainly in the following aspects:

1. The application of new materials: With the continuous emergence of new materials, the materials of polyurethane rubber rolls will be constantly updated. For example, new polymer materials, nanomaterials, etc., will bring more possibilities for the manufacture and application of polyurethane coated rolls.

2. Automated production: With the continuous development of automated production technology, the production of polyurethane rubber rolls will also be more intelligent and automated. This will greatly improve production efficiency and quality.
