轮胎胶帘布压延辊温的选择

Adjustment of Roll Temperature for Calendering Tire Cord

总结了压延辊温选择的经验，即主要从胶料、骨架材料、压延方法及设备４个方面来考虑。胶料中ＳＲ含量增大，辊温应适当降低；人造丝、尼龙和聚酯帘线要根据其特点确定压延辊温；压力贴胶时的辊温比贴胶时要高一些；辊筒特点和循环水温也对辊温控制有较大影响。另外，还进行了实际测试摸索，确定了最佳的压延辊温。

The experiences in the adjustment of roll temperature for calendering tire cord are summarized in view of rubber compound,reinforcement,calendering method and equipment.It is believed that the roll temperature should be lower for the compound with large proportion of SR;the roll temperature should be adjusted for calendering rayon,nylon and polyester according to their respective characteristics;the roll temperature should be adjusted higher for coating than that for covering;the roll temperature adjustment is influenced by the roll design and the circulating water temperature. 
