In the papermaking industry, rubber rollers are a vital component, and their application runs through all key links of paper production. Rubber rollers not only improve production efficiency, but also greatly improve the quality of paper.

This article will discuss in detail why the papermaking industry needs to use rubber rollers, and which links in the papermaking process need to use them.

What are the characteristics of rubber rollers?

The characteristics of rubber rollers give them unique advantages in the papermaking industry:

1. Elasticity: Rubber materials have high elasticity and can quickly return to their original shape after being stressed. This property enables them to effectively handle pulp and paper without damaging them.

2. Wear resistance: Rubber rollers have good wear resistance and can be used for a long time without being easily worn, and are suitable for high-frequency production environments.

3. Corrosion resistance: A variety of chemicals are used in the papermaking process, and rubber materials have strong corrosion resistance to these chemicals and can maintain good performance for a long time.

4. Adhesion performance: The rubber roller can effectively grasp and guide the paper, ensuring the stability and uniformity of the paper during the production process.

Which link in the papermaking industry needs to use rubber rollers?

The links in the papermaking industry that need to use rubber rollers: pulp preparation, paper forming, paper drying, paper coating, paper finishing, etc.

1. Pulp preparation:

Pulp preparation is the first key link in the papermaking process. In this link, rubber rollers are mainly used in the following aspects:

● Squeezing roller: used to squeeze out the water in the pulp to make the pulp drier and more uniform. This process is crucial to the final quality of the paper. The elasticity and wear resistance of the rubber roller enable it to work for a long time under high pressure without damaging the pulp.

● Dispersion roller: used to evenly disperse the fibers in the pulp to ensure the uniformity and strength of the paper. The good adhesion performance of the rubber roller can effectively disperse the fibers and avoid fiber agglomeration.

2. Paper forming:

The application of rubber rollers is particularly important in the paper forming process. This link determines the basic shape and quality of the paper.

● Forming roller: used to spread the pulp evenly on the forming net to form preliminary paper. The elasticity and adhesion of the rubber roller can ensure the uniform distribution of the pulp on the forming net and improve the flatness and uniformity of the paper.

● Pressing roller: After the pulp forms paper, the pressing roller further squeezes out the water to increase the density and strength of the paper. The wear resistance and corrosion resistance of the rubber roller enable it to work stably and long-term under high pressure to ensure the quality of the paper.

3. Paper drying:

Paper drying is a key link in the papermaking process, which directly affects the moisture content and quality of the paper. In this link, the application of rubber rollers is mainly reflected in the following aspects:

● Drying roller: used to dry wet paper through a dryer. The rubber roller can effectively transfer heat and improve drying efficiency. At the same time, its high temperature resistance can work for a long time in a high temperature environment.

● Forming roller: After the paper is dried, the paper is pressed flat by the forming roller to achieve a predetermined thickness and smoothness. The elasticity and wear resistance of the rubber roller enable it to work under high pressure without causing damage to the paper.

4. Paper coating:

Paper coating is an important link to improve the surface quality and characteristics of paper. The application of rubber rollers in this link mainly includes:

● Coating roller: used to evenly apply the coating on the surface of paper to improve the smoothness and printability of the paper. The adhesion and corrosion resistance of the rubber roller enable it to evenly apply the coating without missing or uneven coating.

● Drying roller: After coating, the coating layer is further dried by the drying roller to ensure the firmness and uniformity of the coating. The high temperature resistance of the rubber roller can work for a long time in a high temperature environment to ensure the coating effect.

5. Paper finishing:

Paper finishing is the last link in the papermaking process and determines the final appearance and performance of the paper. The application of rubber rollers in this link mainly includes:

● Cutting roller: used to cut large rolls of paper into the required size and shape. The wear resistance and adhesion of the rubber roller enable it to remain stable during high-speed cutting, ensuring neat and precise cutting.

● Winding roller: used to roll paper into rolls for easy storage and transportation. The elasticity and adhesion of the rubber roller ensure that the paper does not shift or loosen during the winding process, keeping the paper neat and tight.

What are the advantages of rubber rollers in the papermaking industry?

The wide application of rubber rollers in the papermaking industry is mainly due to its following significant advantages:

1. High efficiency: Rubber rollers can work for a long time under high pressure and high speed, improve production efficiency and shorten production cycle.

2. Durability: Rubber rollers have good wear resistance and corrosion resistance, can maintain good performance for a long time in harsh working environments, reduce the frequency of maintenance and replacement, and reduce production costs.

3. Versatility: Rubber rollers are suitable for multiple links in the papermaking process, from pulp preparation, paper forming to paper drying, coating and finishing, and can meet various production needs.

4. High quality: Rubber rollers can effectively improve the quality of paper, ensure the uniformity, flatness and smoothness of paper, and enhance the market competitiveness of paper.
