摘　　要：高密度聚乙烯环管淤浆工艺生产过程中会出现黏壁现象,反应器的黏壁是普遍存在的问题,这也是多种因素相互作用造成的。低聚物的生成、聚合温度高、静电、共聚单体等都有可能使反应器产生黏壁现象。通过合理控制共聚单体浓度,控制反应温度,保持反应器内壁光洁度,控制反应器内固含量等方法,可有效减少反应器黏壁概率,延长装置的运行周期。The phenomenon of sticky wall appears during the production process of high density polyethylene slurry loop process.The wall sticking of the reactor is a common problem,caused by the interaction of many factors,the generation of oligomers,high polymerization temperature,electrostatics,comonomers,etc.have the potential to make the reactor produce wall phenomena.The reactor wall probabilities can be reduced and the operation cycle of the device extended by the methods such as rational control of the comonomer concentration,control of the reaction temperature,keeping the internal wall finish of the reactor,and control of the internal solid content of the reactor.
