The surface of the mechanical function roller is sprayed with Teflon coating

       Mechanical function rolls are used in various industries, such as calender rolls, rewinder rolls, sizing rolls used in the paper industry, rolls and laminar flow rolls used in the iron and steel metallurgy industry, and guide rolls used in other industries. In the long-term operation, there will be wear or corrosion. Because the cost of the roller is relatively high, when the surface treatment of the roller is carried out, most of them will use thermal spray processing, laser cladding processing, spray welding and other processes to strengthen the surface.



There are also a wide range of materials suitable for roller surface treatment, such as tungsten carbide, Teflon, metal alloys, etc. The metal coatings prepared by different processes and materials have different functions. Such as Teflon coating, the Teflon coating prepared by thermal spraying processing technology, has good performance.



Teflon coating is also one of the metal protective coatings. Because it is hardly soluble in solvent, it is known as "non-stick coating". The Teflon coating prepared by thermal spraying process is mainly Features are as follows:



1. Non-adhesive: Teflon is not easy to be compatible, and also shows good non-adhesive performance;



2. Wear resistance: Under high load, it has excellent wear resistance, and under certain load, it has the dual advantages of wear resistance and non-adhesion;



3. Corrosion resistance: Teflon is almost insoluble in chemical substances, giving it good corrosion resistance;

4. Heat resistance: Teflon can withstand high temperature up to 300 °C in a short time, generally it can be used continuously between 240 °C and 260 °C, and has remarkable stability.
