Melt kuyerera indekisi yeyakaderera-density polyethylene kutsunga kwakavakirwa pane molecular uremu uye branching zvivakwa
Ukoshi hweMFI hwakatorwa pamapepa akawanda hunoreva huwandu hwepolymer hunoburitswa kuburikidza neinongedzo inozivikanwa yakapihwa (kufa) uye inoratidzwa sehuwandu mug/10 mins kana yeMelt Volume Rate mucm3 /10mins.
yakaderera-density polyethylene (LDPE) inoratidzirwa zvichienderana neMelt Flow Index yavo (MFI).LDPE's MFI yakabatana neavhareji mamorekuru huremu (Mw).Kutariswa kwezvidzidzo zvekuenzanisira pane LDPE reactors anowanikwa mumabhuku akavhurika anoratidza mutsauko wakakura pakati pevatsvaguri wekuwirirana kweMFI-Mw, saka tsvakiridzo yekuburitsa hukama hwakavimbika inofanirwa kuitwa.Tsvagiridzo iyi inounganidza data rakasiyana rekuyedza uye remaindasitiri emhando dzakasiyana dzechigadzirwa cheLDPE.Empirical corelations pakati peMFI neMw inogadzirwa uye kuongororwa kweMFI neMw hukama kunogadziriswa.Iyo yezana yekukanganisa pakati peiyo modhi yekufungidzira uye data yemaindasitiri inosiyana kubva pa0.1% kusvika 2.4% iyo inogona kutariswa kushoma.Iyo isiri mutsara modhi yakawanikwa inoratidza kugona kweiyo yakagadziridzwa equation kutsanangura kusiyanisa kwemaindasitiri data, nokudaro zvichibvumira kuvimba kukuru mukufanotaura kweLDPE's MFI.
