Surface treatment
Surface treatment is the last and most critical process in the production of rubber rollers. The surface grinding state directly influences the performance of the rubber rollers. At present, there are many kinds of grinding methods, but the main ones are mechanical turning and polishing. For this reason, the grinding methods, grinding tools and abrasives used are very important, and most companies regard them as technical know-how and maintain an unannounced attitude. The biggest problem is how to solve the heat generation of rubber during grinding and maintain the best deflection of the surface after grinding.
In addition to grinding the surface of the rubber roller, it must be thoroughly cleaned to remove the rubber powder attached to the surface. If the requirements are higher, the surface must be further polished. Some surfaces are coated with resin paint, latex paint, and magnetic powder. , Electrostatic powder, etc. At the same time, it can also be electroplated with a layer of plating, or chemical oxidation treatment, etc., in order to achieve the purpose of light sensitivity, corrosion resistance, magnetization and conductivity.
With the continuous development of rubber rollers, the coating technology of the rubber roller surface has also been rapidly improved, and the traditional method of coating rubber has begun to change the performance of rubber rollers. Specifically, it is to use the coating method to change and give new properties to the rubber roller. For example, the use of equipment such as calenders and scrapers to add oil shielding layer to achieve the purpose of improving oil resistance, etc. Although the shape and material of the rubber roller are the same as the original, its function has undergone great changes, and some have become Functional rubber roller, this kind of surface treatment technology will be very promising in the future.
