Bambancin Maɓalli-UHMW vs HDPE
UHMW da HDPE polymers ne na thermoplastic waɗanda ke da kamanni iri ɗaya.Babban bambanci tsakanin UHMW da HDPE shine UHMW yana ƙunshe da dogayen sarƙoƙi na polymer tare da ma'aunin ma'auni masu girma yayin da HDPE yana da babban ƙarfin-zuwa-yawa.
UHMW yana nufin Ultra High Molecular Weight polyethylene.Hakanan ana nuna shi ta UHMWPE.Kalmar HDPE tana nufin High Density Polyethylene.
Menene UHMW?
UHMW polyethylene ne mai nauyin ultra-high na kwayoyin.Yana da nau'in polymer na thermoplastic.Wannan fili na polymer yana ƙunshe da sarƙoƙi na polymer dogayen ma'aunin nauyi masu nauyi (kusan miliyan 5-9 amu).Saboda haka, UHMW yana da mafi girman nauyin kwayoyin halitta.Duk da haka, bayyanar wannan fili ba shi da bambanci da na HDPE.
