Yuav ua li cas Polyethylene fiber ntau ua nyob rau hauv cov kub?
Polyethylene fibers thiab kub siab: Taw qhia
Polyethylene fibers, tshwj xeeb yog Ultra- siab} qhov kev xaiv qhov hnyav (UHMWPE), ua rau lawv xaiv cov ntawv zoo, suav nrog cov cuab yeej muaj zog, suav nrog lub cev armor. Txawm li cas los xij, lawv qhov kev ua tau zoo ntawm kev nce siab kub yog qhov tseem ceeb cuam tshuam rau lawv txoj kev ntseeg tau thiab tsis tu ncua.
Polyethylene Fiber Ntau Qauv
UHMWPE fibers yog tsim tau ntev, kev taw qhia heev polymer peeler saw nrog qib siab ntawm crystallinity. Cov qauv no cuam tshuam tshwj xeeb cov cuab yeej siv tshuab, suav nrog lub zog tensile txog 4 GPA thiab qhov ntom ntom ntawm kwv yees li 0.97 g / cm³. Txawm li cas los xij, qhov no crystalloinity thiab kev taw qhia kuj ua rau cov fibers raug rau kev ua pa hluav taws xob, uas muaj kev sib haum xeeb.
Thermal Didradation Mechanism
Kev kub siab muaj peev xwm tuaj yeem ua rau mob voos ntawm polyethylene fibers. Cov txheej txheem no cuam tshuam ntawm cov carbon {{1} centered dawb radicals vim yog cov cleavage ntawm c} C bonds, uas ua rau muaj kev txo qis hauv cov hniav puas loj. Lub xub ntiag ntawm cov radicals dawb thiab tom qab saw txuas tsis zoo cuam tshuam cov khoom siv me me ntawm cov fiber.
Neeg kho tshuab hloov
High - kub} Cov kab mob kub siab tseem ceeb cuam tshuam cov khoom siv ntawm polyethylene fibers. Ob lub tensile thiab shear lub zog txo nrog kev ua kom muaj kev ntxhov siab. Piv txwv li, kev ntsuam xyuas cov txiaj ntsig tau qhia tau tias kub nias kub thiab sijhawm nce ntxiv thiab nce qib, mus txog qhov kev ua tau zoo nyob rau hauv cov xwm txheej tshwj xeeb.
Crystal Morphology Hloov
Kev ntsuas kub siab rau kev hloov pauv ntawm cov siv lead ua morphology ntawm polyethylene fibers. Dav {- lub kaum sab xis x {}} ray ecogen diffusion rau hauv cov khoom siv thiab exacerbates oxidarative degradation. Qhov kev hloov pauv morphological ua rau txo qis hauv cov caj pas loj thiab tsis muaj zog neeg kho tshuab.
Qhov cuam tshuam ntawm Kev Laus Kub
Kev laus cua sov tuaj yeem cuam tshuam rau lub sijhawm ntev {{}} lub sij hawm ruaj khov ntawm polyethylene fibers. Cov kev tsis xws luag thiab kev tsis txaus ntseeg tau qhia tias lub sijhawm ua tau ntxiv mus nrawm oxidation, ua rau cov kev ntsuam xyuas saw thiab ploj ntawm kev siv tshuab. Cov khoom siv fiber ntau tsis zoo rau lub sijhawm, ua rau lawv siv hauv kev siv xws li kev tiv thaiv kev tiv thaiv.
Lub luag haujlwm ntawm kev ua haujlwm
Kev ua kom zoo tshaj plaws, xws li kub, lub sijhawm, thiab lub zog thaum lub tshuab kub, yog qhov tseem ceeb rau kev tswj cov khoom siv ntawm polyethylene fibers. Kev ntsuam xyuas tau qhia tias tsis pom tias cov khoom siv cov khoom siv hluav taws xob ua kom pom cov khoom siv ntawm 130 degree, nrog lub zog tensile ntawm 595.43 MPa. Kho lub siab kuj tseem tuaj yeem cuam tshuam ntau yam cuam tshuam txog kev ua kom muaj zog.
Kev Tiv Thaiv thiab Qhov Kev Ntsuas Lub Zog
Kev tiv thaiv kev tiv thaiv xws li txheej ci lossis cov ntxiv tuaj yeem txhim kho lub thermal stability ntawm polyethylene fibers. Cov kev ntsuas no pab kom muaj cov fiber kom muaj lub zog thiab lub zog ua kom tsis tu ncua nyob rau hauv high- tej kev mob kub. Cov chaw muab khoom Suav tau nquag tsim cov thev naus laus zis los txhim kho fiber ntau ua haujlwm.
Sib piv nrog Lwm Cov Khoom Siv
Polyethylene muaj kev sib npaug zoo ntawm lub zog thiab qhov hnyav piv rau lwm cov ntaub ntawv xws li para}} aramid fiber ntau thiab hlau. Txawm li cas los xij, lawv qis qis stability muaj kev ua kom muaj kev txhim kho hauv kev ua thiab kev tiv thaiv kom paub tseeb kev sib tw ua tau zoo. Kev coj ua zoo tshaj plaws hauv cov khoom siv kev txhawb nqa yog qhov tseem ceeb los tswj kev ua thawj coj ua lag luam.
Yav Tom Ntej R & D
Kev tshawb fawb txuas ntxiv yog tsom rau kev nkag siab txog cov kev hloov pauv molecular hauv polyethylene fibers thaum kub. Kev tsim cov ntaub ntawv qib siab thiab thev naus laus zis kom txo thicko -} ecidative℃yog qhov tseem ceeb tshaj plaws. Sab saum toj -}} Tier Suav cov khoom lag luam yog nyob rau ntawm qhov kev tshawb fawb no thiab tau cog lus los muab cov kev daws teeb meem superior.
