Application Of High-Efficiency Tangential Belt
High speed tangential belt is especially suitable for high speed transmission in textile industry, such as air suction, air spinning, carding machine, twister, stretch yarn machine, covering yarn machine, extra-long ring spinning, fancy twisting machine, knitting machine and so on.
How to solve the problem that the hardness of the secondary vulcanization is seriously reduced?
Cause Analysis:
1. High content of low boiling matter;
2. Oxidative degradation of glue, containing acid and alkali
Measures:
1. The temperature and time must be guaranteed when vacuuming;
2. When removing low boiling substances from raw rubber, it is necessary to reach the process temperature and time to remove all acids and alkalis;
3. The use of additives should prevent acid and alkali, and ensure neutrality;
4. The exhaust of the oven for secondary vulcanization should be good to prevent oxidative degradation;
5. Use hardening agent.
How to solve the problem of unpalatable powder during mixing?
Cause Analysis:
1. Less dispersant;
2. The hydroxyl content in the dispersant is too low;
3. The molecular weight of raw rubber is high and the molecular weight distribution is too narrow;
4. Excessive branching of raw rubber chains increases the steric hindrance effect;
5. Poor equipment shear;
6. The addition of carbon black is out of proportion to the amount of additives;
7. The temperature is too low
Measures:
1. Add dispersant (most feasible);
2. The test results of the dispersant should be accurate;
3. The molecular weight distribution should be uniform, and the dispersant dosage should be adjusted;
4. Reduce chain branching and reduce steric hindrance effect (feasible, limited);
5. When feeding, add in proportion to the dispersant;
6. Properly increase the temperature (feasible)
