Application Of Roller Covering
Roller covering is used to increase the friction coefficient. It is usually used for fabric traction in different processes of textile industry, such as in various air-jet, water jet, rapier, shuttle looms, cloth inspection machines, cloth guide roller of finishing equipment after printing and dyeing, paper making equipment, etc.
How to solve the problem of poor resilience?
Cause Analysis:
1. The raw rubber vinyl formula is unreasonable;
2. Too much dispersant;
3. The cold refining time is not enough, and the wettability of white carbon black and raw rubber is poor;
4. The cold refining temperature is high
Measures:
1. Add appropriate amount of polyvinyl silicone oil to increase the amount of vinyl (the most effective);
2. The dosage of dispersant should be appropriate;
3. After the white carbon black is eaten, it is refrigerated until it is extended for 45 minutes;
4. Ensure the cold refining temperature.
How to solve the problem of immature vulcanization?
Cause Analysis:
1. No vinyl or too little vinyl;
2. Less or no vulcanizing agent or failure;
3. Low vulcanization temperature;
4. Short vulcanization time
Measures:
1. Add polyvinyl silicone oil or high vinyl raw rubber (the most effective);
2. Buy high-quality vulcanizing agent;
3. Appropriate vulcanization temperature;
4. Control the vulcanization time according to the thickness of the product
