Cov polyethylene fiber uas muaj zog heev (UHMWPE), tseem hu ua cov fiber PE uas muaj zog heev, yog ib qho ntawm peb cov fibers thev naus laus zis hauv ntiaj teb niaj hnub no (carbon fiber, aramid fiber, thiab ultra-high molecular weight polyethylene fiber), thiab kuj yog cov fiber uas tawv tshaj plaws hauv ntiaj teb. Nws sib dua li ntawv thiab tawv li hlau, muaj zog 15 npaug ntawm hlau, thiab ob npaug ntawm carbon fiber thiab aramid 1414 (Kevlar fiber). Tam sim no nws yog cov khoom siv tseem ceeb rau kev tsim cov tsho tiv thaiv mos txwv.
Nws qhov hnyav molecular yog li ntawm 1.5 lab txog 8 lab, uas yog ntau dua li cov fibers ib txwm muaj, uas kuj yog keeb kwm ntawm nws lub npe, thiab nws muaj kev ua tau zoo heev.

1. Cov qauv no ntom thiab muaj zog tshuaj lom neeg inertness, thiab cov kua qaub-base muaj zog thiab cov organic solvents tsis muaj feem cuam tshuam rau nws lub zog.
2. Qhov ceev tsuas yog 0.97 grams ib cubic centimeter, thiab nws tuaj yeem ntab rau ntawm qhov dej.
3. Tus nqi nqus dej tsawg heev, thiab feem ntau tsis tas yuav qhuav ua ntej tsim thiab ua tiav.
4. Nws muaj kev tiv taus huab cua zoo heev thiab tiv taus UV. Tom qab 1500 teev raug tshav ntuj, qhov ceev ntawm cov fiber tseem khaws cia siab txog li 80%.
5. Nws muaj kev tiv thaiv zoo heev rau kev tawg thiab siv tau ua lub phaj tiv thaiv rau cov chaw tsim hluav taws xob nuclear.
6. Tsis tshua muaj kev tiv taus kub, nws tseem muaj ductility ntawm cov kua helium kub (-269 ℃), thaum cov fibers aramid poob lawv cov kev tiv thaiv mos txwv ntawm -30 ℃; Nws kuj tseem tuaj yeem tswj tau lub zog cuam tshuam zoo heev hauv cov kua nitrogen (-195 ℃), ib qho yam ntxwv uas lwm cov yas tsis muaj, thiab yog li ntawd tuaj yeem siv ua cov khoom tiv taus kub qis hauv kev lag luam nuclear.
7. Qhov kev tiv thaiv kev hnav, kev tiv thaiv khoov, thiab kev ua haujlwm tensile qaug zog ntawm cov fibers polyethylene hnyav molecular siab kuj yog qhov muaj zog tshaj plaws ntawm cov fibers ua tau zoo uas twb muaj lawm, nrog rau kev tiv thaiv kev cuam tshuam zoo thiab kev txiav tawv. Cov fiber polyethylene hnyav molecular siab heev uas tsuas yog ib feem plaub ntawm cov plaub hau tuab yog qhov nyuaj rau txiav nrog txiab. Cov ntaub ua tiav yuav tsum tau txiav siv lub tshuab tshwj xeeb.
8. UHMWPE kuj muaj kev ua tau zoo heev ntawm kev rwb thaiv hluav taws xob.
9. Huv si thiab tsis muaj tshuaj lom, siv tau rau kev sib cuag nrog zaub mov thiab tshuaj. Piv nrog rau lwm cov yas engineering, cov fibers polyethylene hnyav molecular siab heev feem ntau muaj qhov tsis zoo xws li tsis tshua muaj kev tiv taus cua sov, tawv, thiab tawv, tab sis tuaj yeem txhim kho los ntawm cov txheej txheem xws li kev sau thiab kev sib txuas; Los ntawm qhov pom ntawm kev tiv taus cua sov, qhov chaw yaj ntawm UHMWPE (136 ℃) feem ntau zoo ib yam li cov polyethylene ib txwm muaj, tab sis vim nws qhov hnyav molecular loj thiab viscosity yaj siab, nws nyuaj rau ua tiav.
