This type of rubber roller has moderate hardness and elasticity, high oil resistance, solvent resistance, wear resistance, and shape stability. Soft rollers are generally made of materials such as SBR, CR, and PU. The surface of the hard stick was originally made of copper material and later repaired with polyester resin instead of printing and dyeing rollers:
In work engineering, printing rollers often experience wear and tear, holes, and other phenomena. If a new roller is replaced, the cost will be too high and it will affect the production schedule. Rubber repair agents can be used for repair
Repair process, taking BD916 rubber repair agent produced by Xiangfan Lianji Adhesive Factory as an example:
1. Surface treatment: roughen the surface to be repaired, clean, remove dirt, degrease, and air dry.
2. For adhesive repair, pour rubber repair agent curing agent group B into the iron container of main agent group A and stir quickly and evenly (A: B=1:1), then pour it onto the area to be repaired and smooth it out Curing: It can be used after curing at room temperature for 4-6 hours.

The surface of the hard stick was originally made of copper material, but later replaced with polyester resin for printing and dyeing rubber rollers. Fault and solution:
Crystallization and calcification on the surface of paper rollers;
The surface of the paper making rubber roller is prone to scratches and tingling;
Premature cracking and aging of rubber rollers;
De ink;
