In the modern industrialized papermaking process, equipment performance and durability play a vital role in production efficiency and product quality. Tungsten carbide coating roller has been widely used in the paper industry due to its excellent physical and chemical properties.

This article will discuss why the paper industry needs to use tungsten carbide roller, and which aspects of paper production require the use of this equipment.

Basic characteristics of tungsten carbide coating roller

The tungsten carbide coating roller is made by applying a layer of tungsten carbide coating on the surface of the roller. This coating material is well-known in industrial applications for its excellent performance. The main features of tungsten carbide coating roller include:

    ● High hardness and wear resistance: The hardness of tungsten carbide is close to diamond, which can effectively resist various forms of wear and significantly extend the service life of the rollers.

    ● High corrosion resistance: Tungsten carbide coating has extremely high resistance to most chemicals and can be used in corrosive environments for a long time.

    ● Good thermal stability: Tungsten carbide coating can still maintain its physical and chemical properties under high temperature conditions, making it suitable for high temperature operating environments.

    ● Low friction coefficient: Tungsten carbide coating has a low friction coefficient, which can reduce energy consumption and improve production efficiency.

What are the applications of tungsten carbide roller in the paper industry?

In the papermaking industry, tungsten carbide coating roller is mainly used in pulping, papermaking, coating and calendering. The following are the main links in the papermaking industry that require the use of tungsten carbide coating roller:

1. Pulp making process:

In the pulping process of papermaking, raw materials need to go through multiple processes such as crushing, mixing and chemical treatment. These processes need to be carried out under high temperature, high pressure and corrosive environment. The tungsten carbide coating roller plays an important role in the pulping process:

    ● Crushing and mixing: During the crushing and mixing process, the tungsten carbide coating roller can provide uniform pressure and stable temperature to ensure full mixing and uniform distribution of raw materials. The high hardness and wear resistance of tungsten carbide coating allows it to work in high-pressure environments for a long time without wear.

    ● Chemical treatment: During the chemical treatment process, the tungsten carbide roller can effectively resist chemical corrosion and ensure the stability and consistency of the treatment process. Its excellent corrosion resistance can extend the service life of equipment and reduce maintenance costs and downtime.

2. Papermaking process:

In the papermaking process, pulp needs to go through multiple processes such as shaping, pressing and drying. The tungsten carbide coating roller also plays a key role in these processes:

    ● Forming process: During the forming process, the tungsten carbide coating roller can provide uniform pressure and stable temperature to ensure the uniformity and smoothness of the paper. The low friction coefficient of tungsten carbide coating can reduce energy consumption and improve molding efficiency.

    ● Pressing process: During the pressing process, paper needs to go through multiple pressing processes to remove excess moisture. The high hardness and wear resistance of tungsten carbide coating roller allows it to work for a long time in a high-pressure environment, improving pressing efficiency and paper quality.

    ● Drying process: During the drying process, the tungsten carbide coating roller can provide stable temperature to ensure the drying effect of the paper. Its good thermal stability can maintain its performance in high temperature environments and ensure the efficiency and stability of the drying process.

3. Coating and calendering process:

During the coating and calendering process of papermaking, paper needs to go through multiple processes to improve its surface quality and physical properties. The tungsten carbide coating roller plays an important role in these processes:

    ● Coating process: During the coating process, the tungsten carbide coating roller can provide uniform coating thickness and ensure consistent coating quality. The low friction coefficient of tungsten carbide coating can reduce paint waste and improve coating efficiency.

    ● Calendering process: During the calendering process, the paper needs to go through multiple calendering processes to improve its surface gloss and smoothness. The high hardness and wear resistance of the tungsten carbide coating roller enables it to work for a long time in a high-pressure environment, improving the calendering effect and paper quality.
