PP ၏ထုတ်လုပ်မှုဖြစ်စဉ်ကို(2)

လုပ်ငန်းစဉ်ပါရှိပါတယ်။: (1) System တွင် Solvent မထည့်ပါ။, propylene monomer သည် ရေနွေးအိုးအတွင်းရှိ ဓာတ်ပေါင်းဖိုရှိ အရည်အဆင့်တွင် ပေါ်လီမာပြုလုပ်သည်။, နှင့် ethylene propylene သည် fluidized bed ဓာတ်ပေါင်းဖိုရှိ ဓာတ်ငွေ့အဆင့်တွင် ပိုလီမာပြုလုပ်ထားသည်။; (2) ရိုးရှင်းသောလုပ်ငန်းစဉ်, ပစ္စည်းကိရိယာနည်းတယ်။, ရင်းနှီးမြှုပ်နှံမှုနည်းတယ်။, low power consumption and production cost; (3) polymerization is carried out in the kettle stirring reactor (Hypol process) or the loop reactor (Spheripol process) Random copolymerization and block copolymerization were carried out in a stirred bed reactor.

The typical representative of adopting liquid-phase bulk method is spherizone liquid-phase bulk method process of Basel company. Spherizone is a gas-phase circulation technology, which uses Ziegler Natta catalyst to produce polymer with high crystallinity, rigidity and homogeneity, while maintaining toughness and processability. It can produce highly uniform multi monomer resin or bimodal homopolymer in a single reactor. There are two interconnected areas in spherizone cycle reaction. Different areas play the role of gas-phase and liquid-phase loop reactor of other processes. These two regions can produce resins with different relative molecular weight or monomer composition distribution, which enlarges the performance range of polypropylene.
