Customized Paper Conveying Roll with Wear-resistant Ceramic Coating

一、The core advantages of the paper conveying rollers with ceramic coating are as follows:

    1. Extremely high wear resistance, significantly extending the service life.

    The ceramic coating can effectively solve the continuous friction, erosion and scraping of paper, cloth and slurry on the rollers during the paper production process. It significantly enhances the resistance to erosion and abrasion, and can multiply the service life of the rollers, greatly reducing the frequency of equipment replacement and downtime for maintenance.

    2. Resistant to acid and alkali corrosion, suitable for humid chemical industries.

    The ceramic material has extremely strong chemical stability, which can effectively improve the long-term humid environment in the paper production workshop. The media such as white water, slurry, sizing agent, bleaching auxiliary agent, etc., contain weak acids and weak alkalis. Ordinary metal rollers are prone to pitting, rusting and peeling.

    3. Excellent surface performance, significantly improving the quality of the paper produced.

    The good surface roughness can be adapted to anti-slip, anti-deviation and anti-wrinkling conditions according to process requirements. The excellent anti-adhesion and hydrophobic properties can effectively reduce paper defects such as paper breakage, paper surface scratches, bulging and indentation, and are suitable for high-speed continuous production.

    4. Strong thermal stability, suitable for alternating high and low temperature working conditions.

    The ceramic coating has high temperature resistance and a low thermal expansion coefficient, which can withstand the complex production environment of high temperature and high humidity for a long time. It is suitable for multiple process scenarios such as drying sections and wet paper conveying sections.

    5. Insulating and anti-static, optimizing the effect of high-speed paper conveying.

    The ceramic-coated rollers have good insulation and anti-static properties, which can effectively disperse production static electricity, avoid static electricity accumulation that causes production abnormalities, and significantly improve the stability of high-speed paper machines and special paper production.

    6. Low maintenance cost and high overall economic benefits.

    Compared with ordinary rollers, although the single processing cost of ceramic-coated rollers is slightly higher, due to their extremely long service life, low failure rate and less downtime losses, the overall maintenance cost of long-term production is significantly reduced.

二、Industry application situation

    At present, plasma-sprayed ceramic-coated rollers have been widely popularly applied in all process scenarios of various paper production lines, and are the standard roller reinforcement solution for high-speed paper machines and medium-to-high-end paper production lines. They are gradually replacing traditional chrome plating, rubber coating and stainless steel rollers. Specific application scenarios are as follows:

    1. Wet section conveying rollers (high humidity, slurry erosion conditions)

    2. Drying section rollers (high temperature, temperature variation conditions)

    3. Precision rollers in pressing, finishing processes

    4. High-speed paper machines and special paper production lines

    5. Coating, sizing auxiliary rollers
