Abstract

В изобретении описано применение в производстве полиолефинов суспензионного петлевого реактора, в котором все внутренние части, находящиеся в контакте с суспензией, вначале полируют механическим способом до уровня максимально 70 СКЗ шероховатости и впоследствии полируют с помощью химического или электрохимического процесса до конечного уровня максимально 40 СКЗ шероховатости.
