Cov iav fiber ntau rab koob-punched pom cov khoom yog cov khoom siv ntsuas kub siab nrog cov qauv tsim nyog thiab kev ua haujlwm zoo heev. Feem ntau yog ua los ntawm cov iav fibers, nws yog tsim los rau hauv cov ntaub zoo li nonwoven los ntawm cov txheej txheem koob-punching uas intertwines cov fibers. Hauv qab no yog cov ncauj lus kom ntxaws txog cov khoom siv no:
I. Cov khoom siv cov khoom siv thiab cov txheej txheem tsim khoom
Cov Khoom Siv Cov Khoom Siv: Nws siv cov iav fibers ua cov khoom siv raw, feem ntau xaiv E-iav fibers vim lawv cov tshuaj tiv thaiv zoo tshaj thiab ruaj khov.
Kev tsim khoom: Tom qab sib txuas, cov iav tws, cov iav ntim cov roj ntsha lev undergoes, cov txheej txheem tshuab hluav taws xob, txhawb cov khoom siv fiber ntau los tsim cov khoom kawg.
Ii. Cov yam ntxwv tseem ceeb
Cov Kub Kub Kuj: Cov iav fiber ntau rab koob-punched pom cov khoom pov thawj ua kom zoo tshaj plaws-kub tiv taus, feem ntau ua kom muaj kev kub ntxhov siab txog 700 degree tsis muaj deformation lossis embrittlement.
Corrosion Kuj: Sib nrug los ntawm hydrofluoric acid thiab kub-kub muaj zog alkalis, nws qhia tau hais tias muaj tshuaj lom neeg ruaj ntseg tiv thaiv lwm yam xov xwm, ua kom ntev siv nyob rau hauv corrosive ib puag ncig yam tsis muaj kev ua haujlwm degradation.
Siab Zog: Cov txheej txheem koob-punching nruj nreem intertwines fibers, uas ua rau muaj zog txhua yam muaj zog thiab abrasion kuj.
Siab porosity: Cov fibers tsim ib leeg-fiber, peb-dimensional microporous qauv nrog lub siab porosity, txo cov roj pom tsis kam thiab ua rau nws muaj txiaj ntsig zoo rau cov khoom siv ntsuas kub.
Suab Absorption thiab Shock Absorption: Cov khoom siv zoo dampens suab nrov thiab kev vibrations vim nws lub suab zoo thiab kev poob siab absorbing zog.
Cov rwb thaiv tsev zoo heev: Nrog nws cov cua kub tsis kam, txhua yam muaj zog, thiab tshuaj lom neeg ruaj khov, nws yog cov khoom siv rwb thaiv tsev zoo.
Zoo heev Resilience: Muaj ntau lub hnab ntim cua ruaj khov, nws nthuav tawm cov kev ua haujlwm zoo, tsis muaj kev cuam tshuam los ntawm kev cuam tshuam lossis kev co.
III. Chaw thov
Cov iav fiber ntau koob-punched pom cov khoom pom dav siv nyob rau hauv ntau yam kub-kub pom scenarios, suav nrog:
Kev lag luam: Rau cov pa luam yeeb huv huv thiab cov hmoov av rov qab rau hauv kev lag luam xws li carbon dub, cov tshuaj, thiab cov pa hluav taws kub, thiab cua sov kub heev hauv ntau qhov chaw ua kom sov.
Kev Lag Luam Automotive: Siv rau lub suab rwb thaiv tsev, lub suab nqus, kev poob siab, thiab nplaim hluav taws xob hauv tsheb.
Kev lag luam kev tsim kho: Rau thermal rwb thaiv tsev nruab nrab ntawm txheej ntawm cov qauv xim thiab cov qauv ntoo, zoo li rau insulating thermal thiab cheesical raj.
Khoom Siv Hauv Tsev: Thermal rwb thaiv tsev ntawm cov khoom siv hluav taws xob vaj huam nyob rau hauv cov tshuab nqus dej txias, microwavavators, tshuab ntxuav tais diav, tshuab ntxuav tais diav, thiab lwm yam khoom siv ntxuav tais diav.
IV. Cov Khoom Siv Lub Cev
Cov khoom siv lub cev ntawm cov iav fiber ntau rab koob-punched filtration cov ntaub ntawv sib txawv sib txawv los ntawm cov khoom lag luam tshwj xeeb thiab feem ntau suav nrog:
Phaus ib qho chaw nyob (grammage): Qhov loj ntawm ib chav tsev, feem ntau qhia hauv g / m².
Thickness: Cov tuab ntawm cov khoom, feem ntau ntsuas hauv mm.
Tensile Breaking zog: Qhov siab tshaj plaws yuam cov khoom tuaj yeem tiv taus thaum muaj nro, feem ntau qhia tias N / 50mm.
Huab cua permeability: Cov khoom siv muaj peev xwm pub roj kom dhau mus, ntsuas ntsuas hauv ML / MISLIZES.
Kub Resistance: Qhov kub siab tshaj plaws uas cov khoom tuaj yeem tiv taus, feem ntau qhia hauv degree.
V. Kev ceev faj
Thaum siv, saib xyuas kom tswj tau cov ntsiab lus pom kev thiab kev ua haujlwm kub kom ntseeg tau tias kev pom kev ua tau zoo thiab cov khoom siv ntev. Tsis tas li ntawd, cov khoom yuav tsum tau muaj kev tiv thaiv los ntawm noo noo thiab compression thaum lub sijhawm kev thauj mus los thiab kom tiv thaiv kev ua phem kev ua haujlwm.
