Rubber Roller Coating Process
In general, rubber roller coating process refers to that the rubber roller factory cover the roller core with rubber and then vulcanized, polished, etc. According to the customer's requirements, the rubber roller is machined to the required size, hardness, color, etc. The rubber roller coating process involves the following processes:
1. Cleaning rubber roller core: If the rubber roll core is a new one, the oil stain on the rubber roller core surface should be cleaned with cleaning agent; If it is an old rubber roll core, the outside layer of the old rubber roller should be removed before cleaning the remaining rubber on the core surface with cleaning agent.
2. Roughening surface treatment on the rubber roller core: The purpose of making roughening surface treatment is to increase the bonding area between the surface of the rubber roll core and the coated rubber, which can make sure that the rubber coating is stably covered on the roller core.
3. Sand blasting processing: After roughening surface treatment on the rubber roller core, rubber roller factory will select different kinds of sand to do sandblasting according to the different material of the roller core. The sandblasting processing is to make the surface of rubber roller rougher, and the bonding between the rubber and the roller core will be better.
4. Rubber coating: The rubber will be extruded on to the roller core after the above treatment. Different coating rubber can meet different requirements. For example, natural rubber coated roller has good ink resistance, polyurethane rubber roller has good wear resistance and pressure resistance, and rubber roller with silicone coating appears to have good high temperature resistance.
5. Roller vulcanizing: It generally takes 10-15 hours for the rubber roller to be vulcanized. After vulcanization, the covered rubber and the core of the rubber roller will be bonded closely.
6. Rubber roller polishing: The rubber rolls need to be polished according to the size required by the customer.
After the above processes, the rubber roller coating process is completed. Then the rubber rollers will be further machined, such as cnc turning, grooved, grinding, according to the customer’s requirements.
