I-Melt flow index yokuzimisela kwe-polyethylene ephantsi kwe-low density esekelwe kwi-molecular weight and branching properties

Ixabiso le-MFI elicatshulwe kwiinkcukacha zedatha libhekiselele kubungakanani bepolymer ekhutshelwa i-orifice eyaziwayo (die) kwaye ichazwe njengobungakanani kwi-g/10 mins okanye kwiMelt Volume Rate kwi-cm3 /10mins.

I-polyethylene ephantsi (i-LDPE) ibonakaliswe ngokusekelwe kwi-Melt Flow Index (MFI).I-MFI ye-LDPE ihambelana ne-avareji yobunzima bemolekyuli (Mw).Isishwankathelo sophononongo lwemodeli kwii-reactors ze-LDPE ezifumanekayo kuncwadi oluvulekileyo lubonisa ukungangqinelani okukhulu phakathi kwabaphandi bonxulumano lwe-MFI-Mw, ngoko ke uphando lokuvelisa ulungelelwaniso oluthembekileyo kufuneka lwenziwe.Olu phando luqokelela idatha eyahlukeneyo yovavanyo kunye nemveliso yamabakala ahlukeneyo emveliso ye-LDPE.Unxulumano olunamandla phakathi kwe-MFI kunye neMw luyaphuhliswa kwaye uhlalutyo lwe-MFI kunye ne-Mw luyalungiswa.Ipesenti yempazamo phakathi kokuqikelelwa kwemodeli kunye neenkcukacha zamashishini zihluka ukusuka kwi-0.1% ukuya kwi-2.4% enokuthi ithathelwe ingqalelo encinci.Imodeli engabonakaliyo efunyenweyo ibonisa ukufaneleka kwe-equation ephuhlisiwe ukuchaza ukuhluka kwedatha yezoshishino, ngaloo ndlela ivumela ukuzithemba okukhulu kwingqikelelo ye-LDPE ye-MFI.
