The paper industry roller with thermal spray coating refers to the application of one or more layers of coating on the surface of the paper machine roller by thermal spray technology to improve the performance and durability of the roller. Thermal spraying is a surface engineering technique in which a sprayed material is heated to a molten or semi-molten state and then sprayed to the surface of the substrate with a high-speed air stream to form a uniform, dense coating.
1. Press roller : Thermal spray coating can improve the wear resistance and corrosion resistance of the press roller, especially in high pressure and humid environments. Coating materials such as tungsten carbide (WC), ceramics or metal alloys can significantly extend the life of the roll.
2. Drying cylinder (drying roller) : The thermal spray coating on the surface of the drying cylinder can provide better corrosion resistance and wear resistance, while maintaining good heat conduction performance, which helps to improve drying efficiency.
3. Mesh roller : Mesh roller is often in contact with wet pulp and chemicals, thermal spray coating can provide additional protection against corrosion and wear.
4. Coating roller : The surface coating of the coating roller is required to be very smooth and wear-resistant, and thermal spraying technology can provide high-quality coating to ensure that the coating is evenly distributed on the surface of the paper.
1、 Improved wear resistance ** : Thermal spray coatings are generally harder than base materials and can resist friction and wear.
2、 Enhanced corrosion resistance ** : The coating material can be selected from alloys or ceramics with good corrosion resistance to protect the roll from chemical attack.
3、 Improved heat transfer ** : For rollers that require heat transfer, such as dryers, thermal spray coatings can be designed to have good heat transfer properties.
4、 Increased production efficiency ** : Reduced downtime and maintenance costs due to improved roller durability, resulting in increased production efficiency.
5、Strong adaptability ** : Suitable coating material and thickness can be selected according to different working environments and requirements.
