1.Molecular hnyav thiab khoom siv zog
UHMWPE: Nws lub cev hnyav feem ntau yog tshaj 1.5 lab (txog 10 lab), thiab nws cov molecular saw ntev yog 10 txog 20 zaug ntawm HDPE. 58. Ultra-ntev molecular saw cov qauv xaus nws nrog siab kawg siab tensile lub zog (ntau dua los yog sib luag rau 110Kj \/ M², ISO 179).
HDPE: nws cov roj molecular yog feem ntau ntawm 100, {}}}}}} mpa mpa cia tsuas yog 1\/4 ntawm ntawm UHMWPE.
2. Hnav tsis kam thiab tus kheej-lubrication
UHMWPE
Nws cov coj tsis kam yog ntau tshaj 10 zaug uas HDPE thiab 6 zaug ntawm cov hlau.
Qhov chaw saum npoo sib txhuam yog tsuas yog 0. {}}. {1 (ze rau roj-dawb lubrication lubricios.
HDPE: Nws muaj cov hnav tsis zoo thiab xav tau kev vam khom ntxiv rau kev ntxiv rau kev ua tau zoo. Nws cov coefficient ntawm kev sib txhuam yog kwv yees li 0. 15-0. 25.
3. Tshuaj Yeem Yuam Kev thiab cov ntsuas kub yoog
UHMWPE
Resistant rau cov muaj zog acids (xws li 98% sulfuric acid), xws li 50% NAOH), thiab cov kuab tshuaj organ {} degree rau {}}} degree.
Nws tseem tswj kev nruj me ntsis hauv cov kua nitrogen (-196 degree).
HDPE: Nws muaj cov tshuaj tsis zoo (tsuas yog tiv taus cov kua qaub tsis muaj zog thiab alkalis), nrog qhov ntsuas kub siab tshaj plaws ntawm kwv yees li {2}} degree rau 110.
4. Qhov sib txawv hauv kev thov teb
UHMWPE
Cov xwm txheej huab: Hnav cov phaj-resistant rau cov mines, inging cov paib rau cov pob tw tsheb, cov tshuaj tiv thaiv hluav taws xob rau cov chaw sib sib zog nqus.
High-kawg xav tau: Belleproof Vest Fibers (lub zog 35Cn \/ dtex), cov zaub mov-qib conveying pipes (FDA muaj ntawv pov thawj).
HDPE
Scenional Science: Cov dej tso dej thiab cov dej ntws tawm thiab tso dej rau dej paug, kev xa tawm roj, kev ua liaj ua teb.
Tus nqi-rhiab ntawm cov chaw: Ntim khoom, tus nqi qis tus nqi 9.
5. Ua thiab Kev Lag Luam
UHMWPE
Kev ua nyuaj yog qhov siab, xav tau kub moulding lossis gel spinning cov txheej txheem, thiab tus nqi yog li 3 txog 5 zaug uas ntawm HDPE.
Haum rau cov khoom lag luam ntxiv ntxiv (xws li roj teeb lithium lithium separators, cov lus nug bellerproof).
HDPE
Nws yog ib qho yooj yim ua tau kub-yaj sib txuas thiab extruded, nrog tus nqi qis thiab haum rau loj-teev ntau lawm.
Lub ntsiab
Xaiv UHMWPE: Thaum nws yog qhov tsim nyog los cuam tshuam nrog huab kev coj, cuam tshuam, kub tsawg lossis cov peev nyiaj ib puag ncig thiab cov peev nyiaj muaj txaus.
Xaiv HDPE: cov kev ua haujlwm ua haujlwm zoo, raug nqi-rhiab scenarios lossis cov uas yuav tsum tau ua.
