Brief introduction of liquid silicone rubber for rubber rollers:
Cots liquid silica gel is a two-component liquid silica gel material used to make the outer layer of rubber rollers. It is environmentally friendly, non-toxic, fluid, low viscosity, low shrinkage. It is suitable for embossing, printing dyeing, coating of films fabrics. Adhesive, plastic compounding, sugar production non-woven fabric manufacturing silicone rubber rollers, etc.
Application of liquid silicone rubber roller:
Liquid silicone rubber rollers can be used for printing rubber rollers, electronic typing (printing) rubber rollers, copier rubber rollers, leather machine rubber rollers, printing dyeing rubber rollers other high-quality silicone rollers. It can also be used for polyethylene calendering, embossing, printing dyeing. film fabric coating adhesive, plastic compounding, corona treatment other machinery, also used as a release roller on sugar production packaging machines, a silicone roller for non-woven fabric manufacturing.
Features of liquid silicone rubber roller:
1. Good liquidity easy operation;
2. High temperature resistance, ozone resistance, chemical inertness non-adhesion to plastics;
3. High tensile tear strength, easy to deform;
4. It can be heated vulcanized to shorten the curing time of silicone;
5. Can be customized according to customer needs (hardness, color, operation interval, etc.)
Special liquid silicone rubber operation for rubber rollers:
Machine operation: Put the AB components into the machine according to the proportion, put the roller core on the adjusted equipment, then mix stir evenly. After the silica gel passes through the machine's glue outlet pipe, the machine Roll the roller core to make the silicone rubber flow evenly on the roller core. The flow rate is adjusted by the machine according to the viscosity hardness of the silicone. After the silicone gel reaches the required thickness, the glue will be stopped. When the machine keeps rolling, it can be stopped after the silicone gel is cured.
Special liquid silicone rubber for rubber roller operation attention:
1. It cannot be in contact with condensed silica gel, nor can it be in contact with water, impurities, organotin catalysts, acids, alkalis other organic compounds containing nitrogen, phosphorus, sulfur, otherwise it will affect the curing of silica gel;
2. Smoking is prohibited during operation to prevent "poisoning" of silica gel;
3. After the ratio is mixed, the silica gel should be used up in time, otherwise it will cause premature curing cannot be used.
