Cause Analysis:
1. Less dispersion dose;
2. The temperature is high during cold smelting, and the glue and filler are not fully infiltrated;
3. Long storage time leads to structuring;
4. Carbon black has small specific surface area and coarse particles;
5. Raw rubber molecules have a dendritic structure;
6. Insufficient cooling after refining;
7. The temperature is too high after extrusion, and it is packaged without sufficient cooling
Measures:
1. Appropriately increase the dispersant (hydroxyl oil or other structural control agents)
2. Control the cold temperature below a certain temperature and extend the cold refining time for 30 minutes
3. Keep the storage period as short as possible, preferably less than 1 month
4. Control the use of raw materials and choose suitable silica gel fillers
5. Ensure that the water content of carbon black is below the specified value
6. Make sure that the raw rubber molecules are in a linear structure
7. Add 0.5-1.0% T-gel silicone oil (the most effective and feasible)
Cause Analysis:
1. Carbon black particles are coarse and difficult to disperse;
2. The low molecular weight has not been removed, and there is fog (atomization) in the vulcanized rubber (especially the extruded rubber, the volatile content must be low);
3. The variables of wrapping rolls are not enough;
4. Dirt in raw materials;
5. Poor sanitation;
6. The equipment is poorly sealed, and dirt enters the glue when vacuuming;
7. Short high temperature time during heat refining;
8. Poor nitrogen charging operation.
Measures:
1. Choose white carbon black with large specific surface area (select Yuanxiang's 813, 811, Sike's 658B, 688 and other carbon blacks) (the most effective and feasible);
2. Ensure high temperature and vacuum time, and re-evacuate;
3. Increase the number of wrapping rolls;
4. Dirty materials are prohibited. After discovery, filter them with 300-350 mesh for 2-3 times;
5. Inspection and sanitation to ensure that the equipment, platen, and tools are clean;
6. To detect the displacement of the sealing ring of the sealing system, it must be tightened and replaced in time;
7. Ensure that the high temperature and time are carried out according to the process card;
8. Ensure nitrogen ventilation.
