Cov khoom zoo heev ntawm UHMWPE fiber ntau

UHMWPE fiber ntau muaj ntau yam zoo heev, xws li cov khoom siv zoo heev, kev cuam tshuam zoo heev, hnav tsis kam, tshuaj tiv thaiv corrosion, zoo heev lub teeb thiab lwm yam.

1. Cov khoom siv zoo heev ntawm UHMWPE fiber ntau.

UHMWPE fiber ntau muaj cov khoom zoo heev.Nyob rau hauv tib txoj kab ceev, lub zog tensile ntawm UHMWPE fiber ntau yog 15 npaug ntawm cov hlua hlau hlau.Nws yog 40% siab dua aramid fiber ntau, uas kuj yog ib qho ntawm peb lub high-tech fibers nyob rau hauv lub ntiaj teb no, thiab 10 lub sij hawm siab tshaj li high-zoo steel fiber thiab zoo tib yam tshuaj fiber.Piv nrog cov hlau, E-iav, nylon, polyamine, carbon fiber thiab boron fiber, nws lub zog thiab modulus yog siab tshaj cov fibers, thiab nws lub zog yog siab tshaj ntawm cov ntaub ntawv zoo tib yam.

2.Kev cuam tshuam zoo heev ntawm UHMWPE fiber ntau

Ultra siab molecular hnyav polyethylene fiber ntau muaj kev cuam tshuam zoo heev.Nws muaj peev xwm nqus tau lub zog thiab tiv thaiv kev cuam tshuam thaum lub sij hawm deformation thiab molding yog siab dua li ntawm aramid fiber thiab carbon fiber, uas kuj yog "peb high-tech fibers nyob rau hauv lub ntiaj teb no".Piv nrog polyamide, aramid, E iav fiber ntau, carbon fiber thiab aramid fiber ntau, UHMWPE fiber ntau dua tag nrho lub zog nqus tshaj qhov cuam tshuam.

3. Zoo heev hnav tsis kam ntawm UHMWPE fiber ntau

Feem ntau hais lus, qhov ntau dua qhov modulus ntawm cov khoom, qhov qis dua hnav tsis kam, tab sis rau UHMWPE fiber ntau, qhov txawv yog qhov tseeb.Vim tias UHMWPE fiber ntau muaj qhov sib txhuam coefficient qis dua, qhov ntau dua qhov modulus, qhov hnyav dua qhov hnav tsis kam.Sib piv cov kev sib txhuam coefficient ntawm UHMWPE fiber ntau nrog cov carbon fiber thiab aramid fiber ntau, qhov hnav tsis kam thiab khoov qaug zog ntawm UHMWPE fiber ntau ntau dua li cov roj carbon fiber ntau thiab aramid fiber ntau.Yog li nws hnav tsis kam yog zoo dua li lwm cov fibers ua haujlwm siab.Vim nws zoo heev hnav tsis kam thiab khoov tsis kam, nws cov kev ua tau zoo kuj zoo dua, thiab nws yog ib qho yooj yim los ua rau lwm yam ntaub ntawv thiab fabrics.

4.Chemical corrosion kuj ntawm UHMWPE fiber ntau

Cov qauv tshuaj ntawm UHMWPE fiber ntau yog qhov yooj yim thiab nws cov khoom siv tshuaj yog qhov ruaj khov.Ntxiv mus, nws muaj cov qauv crystalline zoo heev, uas ua rau nws tsis tshua muaj kev cuam tshuam rau kev tawm tsam ntawm cov noob caj noob ces hauv cov kua qaub muaj zog thiab muaj zog hauv paus, thiab tuaj yeem tswj hwm nws cov khoom qub thiab cov qauv.Yog li ntawd, feem ntau cov tshuaj tsis yooj yim rau corrode nws.Tsuas yog ob peb txoj kev daws teeb meem tuaj yeem ua rau nws o me ntsis, thiab nws cov cuab yeej cuab tam poob qis dua 10%.Lub zog tuav ntawm UHMWPE fiber ntau thiab aramid fiber ntau hauv cov tshuaj sib txawv tau muab piv rau.Kev tiv thaiv corrosion ntawm UHMWPE fiber ntau yog pom tseeb dua li ntawm aramid fiber ntau.Nws yog qhov tshwj xeeb ruaj khov hauv cov kua qaub, alkali thiab ntsev, thiab nws lub zog tsuas yog poob hauv sodium hypochlorite tov.

5.Lub teeb ua haujlwm zoo ntawm UHMWPE fiber ntau

Vim tias cov qauv tshuaj ntawm UHMWPE fiber ntau ruaj khov, nws lub teeb ua haujlwm kuj yog qhov zoo tshaj plaws ntawm high-tech fibers.Aramid fiber ntau tsis yog UV tiv taus thiab tsuas yog siv tau raws li qhov xwm txheej ntawm kev zam lub hnub ncaj qha.Sib piv UHMWPE fiber ntau nrog nylon, aramid nrog siab modulus thiab qis modulus, lub zog tuav ntawm UHMWPE fiber ntau yog ntau dua li ntawm lwm cov fibers.

6.Lwm yam khoom ntawm UHMWPE fiber ntau

UHMWPE fiber ntau kuj muaj cov khoom zoo hydrophobic, dej thiab noo noo tsis kam, hluav taws xob rwb thaiv tsev khoom thiab lub neej ntev tortuous.Nws yog tib lub high-tech fiber ntau uas tuaj yeem ntab rau hauv dej, thiab nws kuj yog ib qho zoo tagnrho cov khoom siv kub.

Tab sis nws kuj muaj nws qhov tsis zoo, uas yog, lub melting point yog tsawg.Thaum lub sij hawm ua, qhov kub thiab txias yuav tsum tsis txhob ntau tshaj 130 ℃, txwv tsis pub, qhov tshwm sim creep yuav tshwm sim thiab lub neej kev pab cuam yuav luv luv vim lub zog tsis muaj zog ntawm molecular chains ntawm UHMWPE fibers.Tsis muaj pawg dyeing ntawm UHMWPE fiber ntau, uas ua rau nws cov dej tsis zoo.Nws yog qhov nyuaj rau cov dyeing nkag mus rau hauv cov fiber ntau, ua rau cov dyeing tsis zoo.Cov kev tsis txaus no cuam tshuam rau thaj tsam ntawm nws daim ntawv thov.
