Ka helu helu hoʻoheheʻe o ka haʻahaʻa haʻahaʻa polyethylene hoʻoholo ma muli o ke kaumaha molekala a me nā waiwai lālā.

ʻO ka waiwai MFI i ʻōlelo ʻia ma nā ʻikepili he nui e pili ana i ka nui o ka polymer i hoʻokuʻu ʻia ma o ka puka i ʻike ʻia (make) a hōʻike ʻia ma ke ʻano he nui i g/10 mins a i ʻole no ka Melt Volume Rate i cm3 /10mins.

ʻIke ʻia ka polyethylene haʻahaʻa haʻahaʻa (LDPE) ma muli o kā lākou Melt Flow Index (MFI).Hoʻopili ʻia ka MFI o LDPE i kona kaumaha molekala (Mw).ʻO kahi hiʻohiʻona o nā haʻawina hoʻohālike e pili ana i nā reactors LDPE i loaʻa i nā puke ākea e hōʻike ana i nā ʻokoʻa nui ma waena o nā mea noiʻi no ka correlation o MFI-Mw, no laila pono e hana ʻia kahi noiʻi e hana i ka correlation hilinaʻi.Hōʻiliʻili kēia noiʻi i nā ʻikepili hoʻokolohua like ʻole a me ka ʻenehana o nā māka huahana LDPE like ʻole.Hoʻokumu ʻia nā hoʻoponopono ʻokoʻa ma waena o MFI a me Mw a ua ʻōlelo ʻia ka nānā ʻana i ka pilina MFI a me Mw.ʻO ka pākēneka o ka hewa ma waena o ka wānana kumu hoʻohālike a me ka ʻikepili ʻoihana mai ka 0.1% a i ka 2.4% hiki ke manaʻo ʻia he haʻahaʻa loa.ʻO ke kumu hoʻohālike nonlinear i loaʻa e hōʻike i ka mākaukau o ka hoʻohālikelike i hoʻomohala ʻia e wehewehe i ka ʻokoʻa o ka ʻikepili ʻoihana, no laila e ʻae ai i ka hilinaʻi nui i ka wānana MFI o LDPE.
