Babban Bambanci–UHMW vs HDPE

UHMW da HDPE polymers ne masu thermoplastic waɗanda suke da kamanni iri ɗaya. Babban bambanci tsakanin UHMW da HDPE shine UHMW yana ɗauke da dogayen sarƙoƙi na polymer tare da nauyin kwayoyin halitta mai yawa yayin da HDPE yana da babban rabo na ƙarfi-da-yawa.

UHMW yana nufin polyethylene mai nauyin ƙwayoyin halitta mai yawa. Haka kuma ana nuna shi da UHMWPE. Kalmar HDPE tana nufin polyethylene mai yawan yawa.

Menene UHMW?

UHMW polyethylene ne mai nauyin kwayoyin halitta mai matuƙar girma. Wani nau'in polymer ne na thermoplastic. Wannan mahaɗin polymer ya ƙunshi sarƙoƙi masu tsayi sosai waɗanda ke da nauyin kwayoyin halitta masu yawa (kimanin amu miliyan 5-9). Saboda haka, UHMW yana da mafi girman yawan kwayoyin halitta. Duk da haka, ba za a iya bambanta bayyanar wannan mahaɗin da na HDPE ba.
