Lub zog siab siab modulus polyethylene fiber ntau manufacturers tau qhia nws cov kev ua tau zoo
(1) Kev cuam tshuam zoo heev
UHMWPE fiber ntau yog cov thermoplastic fiber uas tsis tshua muaj iav hloov kub.Nws muaj zoo toughness thiab absorbs zog nyob rau hauv cov txheej txheem ntawm yas deformation.Yog li ntawd, nws cov khoom sib xyaw tseem muaj cov khoom siv zoo ntawm cov khoom siv siab thiab qis kub.Qhov cuam tshuam tsis kam yog siab dua li ntawm carbon fiber, arylon fiber thiab iav fiber ntau sib xyaw.Qhov tshwj xeeb cuam tshuam tag nrho lub zog nqus Et / P ntawm UHMWPE fiber ntau yog 1.8, 2.6 thiab 3 npaug ntawm carbon fiber, aramide fiber ntau thiab E iav fiber ntau, feem.Lub peev xwm tsis muaj peev xwm ntawm UHMWPE fiber ntau yog 2.5 npaug siab dua li ntawm aramide fiber ntau.Qhov cuam tshuam lub zog ntawm UHMWPE fiber ntau yuav luag zoo ib yam li nylon, thiab lub zog nqus ntawm UHMWPE fiber ntau nyob rau hauv kev kub ceev cuam tshuam yog ob zaug ntawm PPTA fiber ntau thiab nylon fiber ntau.Qhov kev ua tau zoo no yog qhov tsim nyog rau kev ua cov ntaub ntawv mos mos.
(2) Kev ua haujlwm zoo bending
Lub cev hnyav molecular polyethylene fiber ntau muaj cov khoom zoo bending thiab tuaj yeem tsim knitting coils thiab knotting taub hau yam tsis muaj kev tawg.Cov khoom khoov ntawm iav fiber ntau, carbon fiber thiab arylon fiber tsis zoo.Kev sib piv ntawm kev ua cov khoom ntawm ntau cov fibers qhia tau hais tias siab molecular hnyav polyethylene muaj kev sib txuas siab zog thiab lub nplhaib tsim lub zog, thiab UHMWPE fiber ntau muaj lub nplhaib sib sau ua haujlwm zoo dua li aramid fiber.
(3) Creep kuj ntawm fiber ntau
Qhov kev ua tau zoo ntawm HSHMPE fiber ntau nyob ntawm qhov kub thiab txias ntawm qhov chaw ua haujlwm.Lub creep kev ua tau zoo ntawm HSHMPE fiber ntau ntawm 35 ℃ thiab 1g / d load yog qhia nyob rau hauv Table 3. Piv nrog rau cov pa fiber ntau, cov creep kuj ua tau zoo ntawm HSHMPE fiber yog zoo heev.
(4) zoo noo noo tsis kam thiab tshuaj corrosion kuj
Vim yog cov qauv tshuaj yooj yim ntawm polyethylene, nws muaj kev tiv thaiv corrosion zoo.Cov khoom ua los ntawm cov fiber ntau no yuav tsis poob lawv lub zog los ntawm kev sib cuag nrog acids, alkalis, qias neeg dej hiav txwv, thiab lwm yam UHMWPE fiber ntau muaj lub siab molecular orientation thiab crystallization, qhov cross-sectional cheeb tsam ntawm macromolecules yog me me, yog li cov saw saw yog kaw, thiaj li tiv thaiv kom txhob yaig ntawm cov dej molecules thiab tshuaj reagents, kom nws muaj ib tug zoo hnyav solubility kuj.Spectra fibers khaws lawv lub zog tag nrho thaum immersed rau ib nrab xyoo nyob rau hauv ntau yam kev tshaj tawm, xws li dej, roj, kua qaub, thiab cov ntsiab lus daws.Spectra fiber khaws nws lub zog tom qab tso rau hauv dej txog li ob xyoos thiab tseem tiv taus cov kab mob lom.Table 1 - 8 teev lub zog tuav ntawm Spectra fiber thiab Kevlar fiber ntau hauv cov tshuaj lom neeg.UHMWPE fiber ntau macromolecular saw tsis muaj cov nplhaib uas muaj ntxhiab, cov amino pawg, pawg hydroxyl lossis lwm pawg tshuaj lom neeg ua rau muaj kev cuam tshuam reagent, cov crystallinity siab, yog li lub zog hauv ntau qhov chaw caustic yog khaws cia ntawm ntau tshaj 90%, thaum aramid fiber nyob rau hauv muaj zog acid, lub hauv paus muaj zog txo qis heev.
(5) Hnav tsis kam
Kev hnav tsis kam ntawm cov khoom siv feem ntau txo qis nrog cov qauv loj, tab sis rau UHMWPE fiber ntau, qhov sib txawv yog qhov sib txawv, qhov no yog vim nws cov coefficient ntawm kev sib txhuam, yog li nws muaj qhov ua haujlwm siab.Spectra900PE fiber ntau hlua muaj 8 lub sij hawm siab dua lub voj voog tus lej N dua li aramid fiber ntau, thiab muaj ntau dua hnav thiab khoov qaug zog dua li aramid fiber ntau.Vim nws yooj yim ua, nws muaj ib daim ntawv thov kev cia siab nyob rau hauv kev lag luam.Hnav tsis kam ntawm UHMWPE hauv yas yas, ob peb zaug dua carbon steel, Huang Gang hnav-tiv taus, nws hnav tsis kam yog kaum ob lub sij hawm ntau tshaj li cov polyethylene zoo tib yam, thiab nrog cov txheeb ze molecular loj, hnav-tiv taus kev ua tau zoo ntxiv, tab sis Tom qab thaum tus txheeb ze molecular loj nce mus txog ib qho nqi, nws hnav tsis kam yog tsis hloov nrog siab txheeb ze molecular loj.
(6) Hluav taws xob rwb thaiv tsev thiab lub teeb tsis kam
Kev xa tawm ntawm UHMWPE fiber reinforced composites rau radar nthwv dej yog siab dua li cov iav fiber reinforced composites vim tias qhov tsis tshua muaj hluav taws xob tsis tu ncua thiab dielectric poob qhov tseem ceeb thiab ob peb qhov cuam tshuam radar tsis.Lub dielectric tas li ntawm cov khoom siv polyethylene thiab lub zog txuag hluav taws xob yog qhov me me, uas tsim nyog rau kev tsim khoom ntawm ntau yam radomes.Tsis tas li ntawd, lub zog dielectric ntawm UHMWPE yog hais txog 700kV / mm, uas tuaj yeem tswj kev hloov pauv ntawm arc thiab hluav taws xob spark.
Txawm tias tom qab 1500h illumination, lub zog tuav tus nqi ntawm UHMWPE fiber ntau yog li 68 feem pua, thaum lwm cov fibers qis dua 50 feem pua.
