Ultra siab molecular hnyav polyethylene fiber (UHMWPE), tseem hu ua high-strength PE fiber, yog ib tug ntawm peb high-tech fibers nyob rau hauv lub ntiaj teb no niaj hnub no (carbon fiber, aramid fiber, thiab ultra-siab molecular hnyav polyethylene fiber), thiab tseem yog cov tawv fiber ntau nyob hauv lub ntiaj teb.Nws yog lub teeb yuag li ntawv thiab hnyav li hlau, nrog lub zog 15 npaug ntawm cov hlau, thiab ob zaug ntawm carbon fiber thiab aramid 1414 (Kevlar fiber).Tam sim no nws yog cov khoom tseem ceeb rau kev tsim cov tsho tiv thaiv mos txwv.
Nws qhov hnyav molecular li ntawm 1.5 lab mus rau 8 lab, uas yog kaum ob npaug ntawm cov fibers zoo tib yam, uas yog lub hauv paus ntawm nws lub npe, thiab nws muaj kev ua tau zoo heev.

1. Cov qauv yog ntom thiab muaj zog tshuaj inertness, thiab muaj zog acid-puag kev daws teeb meem thiab cov kuab tshuaj organic tsis muaj zog rau nws lub zog.
2. Qhov ceev tsuas yog 0.97 grams ib cubic centimeter, thiab nws tuaj yeem ntab rau saum npoo dej.
3. Cov dej nqus dej tsawg heev, thiab feem ntau tsis tas yuav tsum qhuav ua ntej tsim thiab ua.
4. Nws muaj huab cua zoo tiv thaiv kev laus thiab UV tsis kam.Tom qab 1500 teev ntawm raug tshav ntuj, lub zog fiber ntau tuav tus nqi tseem siab li 80%.
5. Nws muaj kev tiv thaiv zoo heev ntawm cov hluav taws xob hluav taws xob thiab tuaj yeem siv los ua cov phaj thaiv thaiv rau cov nroj tsuag hluav taws xob nuclear.
6. Tsis tshua muaj kub tsis kam, nws tseem muaj ductility ntawm cov kua helium kub (-269 ℃), thaum aramid fibers poob lawv cov mos txwv tsis zoo ntawm -30 ℃;Nws kuj tseem tuaj yeem tuav lub zog zoo heev hauv cov kua nitrogen (-195 ℃), uas yog cov yam ntxwv uas lwm cov yas tsis muaj, thiab tuaj yeem siv los ua cov khoom siv hluav taws xob qis hauv kev lag luam nuclear.
7. Kev hnav tsis kam, khoov tsis kam, thiab tensile qaug zog kev ua tau zoo ntawm ultra-high molecular hnyav polyethylene fibers kuj yog qhov muaj zog tshaj plaws ntawm cov khoom siv fiber ntau uas twb muaj lawm, nrog rau kev ua haujlwm zoo thiab txiav toughness.Ib qho ultra-high molecular hnyav polyethylene fiber uas tsuas yog ib feem peb ntawm cov plaub hau tuab yog nyuaj rau txiav nrog txiab.Cov txheej txheem ua tiav yuav tsum tau txiav nrog lub tshuab tshwj xeeb.
8. UHMWPE kuj muaj cov hluav taws xob rwb thaiv tsev zoo heev.
9. Hygienic thiab tsis muaj tshuaj lom, tuaj yeem siv rau kev sib cuag nrog cov khoom noj thiab tshuaj.Piv nrog rau lwm cov yas engineering, ultra-high molecular hnyav polyethylene fibers feem ntau muaj qhov tsis zoo xws li tsis tshua muaj cua sov, tawv, thiab hardness, tab sis tuaj yeem txhim kho los ntawm txoj kev xws li txhaws thiab sib txuas;Los ntawm qhov kev xav ntawm tshav kub tsis kam, qhov melting point ntawm UHMWPE (136 ℃) feem ntau yog tib yam li cov polyethylene zoo tib yam, tab sis vim nws qhov hnyav molecular thiab siab melting viscosity, nws yog ib qho nyuaj rau kev ua.
