中心分流式低温一步法混炼工艺

介绍中心分流式低温一步法混炼工艺及其优势。中心分流式低温一步法混炼工艺是将传统的多段混炼工艺有机组合为一步混炼工艺：胶料在密炼机中混炼后排入开炼机冷却,通过中央输送系统对称分配到周围多个开炼机上,加入硫黄和促进剂等。与传统的多段混炼工艺相比,该工艺能耗降低27%,生产效率提高200%,产能提高1.5倍,胶料均匀性和加工性能改善,尤其适用于添加白炭黑的低滚动阻力轮胎胶料混炼。

Single Step Mixing Process at Low Temperature with Symmetrical Distribution System

The single step mixing process at low temperature with symmetrical distribution system is introduced in this paper. In the process, the compound is firstly mixed in the internal mixer and cooled on the open mill, and then distributed to a number of open mills, where the sulfur and accelerators are added. Compared with conventional multi-stage mixing process, the new process reduces energy consumption by 27%, increases productivity by 200% and capacity by 150%. With the new process, the uniformity and rubber processing performance are also improved. This process is especially suitable for production of low rolling resistance tire by using silica.
