生产德国巴斯夫PA66 树脂的工艺方式有两种:1间歇聚合法;2连续聚合法。因间歇聚合工艺成熟且具有较大的生产灵活性, 华韵塑料公司出售以间歇聚合法生产工艺为例介绍PA66树脂的生产。间歇聚合生产PA66树脂工艺来自50%的尼龙66 盐水溶液在浓缩器内被浓缩至浓度为80%后排入聚合釜, 80%的尼龙66盐液在聚合釜内经聚合反应后产生熔融的聚合物, 经聚合釜底部的铸带板挤出切粒, 即生成德国巴斯夫PA66树脂湿切片粒子。PA66树脂湿切片粒子经预脱水、筛分后送入中间料仓暂存。足够的PA66树脂湿切片被连续地送至干燥塔内进行干燥, 干燥合格的PA66树脂即被送至成品料仓进行包装。

There are two process methods for producing BASF PA66 resin in Germany: 1. intermittent polymerization; 2. Continuous polymerization method. Due to the mature and flexible batch polymerization process, Huayun Plastic Company introduces the production of PA66 resin using the batch polymerization process as an example. The intermittent polymerization process for producing PA66 resin comes from a 50% nylon 66 salt water solution being concentrated in a concentrator to a concentration of 80% before being discharged into the polymerization kettle. 80% of the nylon 66 salt solution undergoes polymerization reaction in the polymerization kettle to produce molten polymer, which is then extruded and cut into particles through a casting plate at the bottom of the polymerization kettle, generating wet sliced particles of BASF PA66 resin from Germany. PA66 resin wet sliced particles are pre dehydrated and screened before being sent to the intermediate silo for temporary storage. Sufficient wet slices of PA66 resin are continuously sent to the drying tower for drying, and qualified PA66 resin is then sent to the finished product warehouse for packaging.
