Taw qhia
Aramid npuag, tseem hu ua Kevlar npuag, yog ib hom khoom siv hluavtaws uas paub txog nws lub zog, ua kom tsis zoo, thiab ua haujlwm kub. Aramid ntaub yog thawj zaug qhia los ntawm DuPont nyob rau hauv 1965 thiab txij li thaum nws tau pom nws txoj kev mus rau ntau yam kev lag luam thiab kev siv tub rog, nrog rau lub cev armor, aerospace engineering, automotive engineering, thiab ntau dua. Thaum aramid npuag muaj ntau qhov zoo, kuj tseem muaj qhov tsis zoo uas yuav tsum tau txiav txim siab ua ntej xaiv cov khoom no rau ib daim ntawv thov tshwj xeeb.
Qhov zoo ntawm Aramid Fabric
Ua ntej delving rau hauv qhov tsis zoo ntawm aramid ntaub, nws yog ib qho tseem ceeb kom nkag siab txog nws qhov zoo, uas tau ua rau nws yog ib qho khoom siv nrov hauv ntau qhov kev lag luam.
1. Lub zog: Aramid ntaub yog, phaus rau phaus, tsib zaug muaj zog dua hlau. Lub zog no los ntawm kev sib dhos ntawm tus kheej fibers hauv cov ntaub, uas ua rau nws lub zog tensile loj heev.
2. Thaum tshav kub kub Resistance: Aramid ntaub yog heev resistant rau tshav kub, ua rau nws zoo tagnrho rau siv nyob rau hauv daim ntawv thov uas yuav tsum tau kev tiv thaiv los ntawm kub kub. Qhov tseeb, aramid ntaub tuaj yeem tiv taus qhov kub txog li 400 degree (752 degree F) rau lub sijhawm luv luv.
3. Abrasion Resistance: Aramid npuag kuj muaj kev puas tsuaj-resistant, ua rau nws zoo tagnrho rau siv rau hauv daim ntaub ntawv uas yuav tsum tau tiv thaiv hnav thiab tsim kua muag. Nws qhov kev tiv thaiv siab rau kev puas tsuaj los ntawm qhov tseeb tias nws cov fibers yog tawv heev thiab tiv taus kev txiav.
4. Lub teeb yuag: Txawm tias nws lub zog loj heev, aramid ntaub yog qhov hnyav hnyav, ua rau nws zoo tagnrho rau cov ntawv thov uas qhov hnyav yog qhov kev txhawj xeeb, xws li hauv kev tsim hluav taws xob aerospace, qhov hnyav yuav tsum tau khaws cia kom tsawg kawg nkaus rau kev siv roj.
5. Chemical Resistance: Aramid npuag kuj tseem tiv taus ntau yam tshuaj, ua rau nws zoo tagnrho rau kev siv hauv cov ntawv thov uas yuav tsum muaj kev tiv thaiv cov ntaub ntawv corrosive.
Disadvantages ntawm Aramid Fabric
Thaum aramid ntaub muaj ntau qhov zoo, kuj tseem muaj ntau qhov tsis zoo uas yuav tsum tau muab rau hauv kev txiav txim siab.
1. Tus nqi: Ib qho tsis zoo ntawm cov ntaub aramid yog nws cov nqi. Aramid npuag tuaj yeem ua ntau zaus ntau dua li lwm cov ntaub ntawv, xws li polyester lossis nylon. Qhov no tuaj yeem ua rau nws kim heev rau qee yam kev siv.
2. Kev nqus dej: Aramid ntaub kuj paub txog nws cov dej tsis zoo. Thaum nws muaj peev xwm tiv taus ntau yam tshuaj, nws tuaj yeem nqus dej, uas tuaj yeem cuam tshuam nws lub zog thiab kav ntev.
3. UV tsis kam: Aramid npuag kuj yooj yim rau degradation vim raug UV hluav taws xob. Sij hawm dhau mus, kev raug tshav ntuj ntev tuaj yeem ua rau cov ntaub aramid poob nws lub zog, uas tuaj yeem txo nws cov txiaj ntsig hauv qee yam kev siv.
4. Tsis zoo li lwm cov ntaub: Thaum aramid npuag muaj zog, nws tsis hloov tau zoo li lwm cov ntaub xws li nylon lossis polyester. Qhov no tuaj yeem txwv nws siv hauv qee yam kev siv uas yooj yim yog qhov tseem ceeb.
5. tuaj yeem nyuaj rau txiav thiab xaws: Thaum kawg, aramid ntaub tuaj yeem nyuaj rau txiav thiab xaws. Nws lub zog siab thiab tawv tawv tuaj yeem ua rau nws nyuaj rau kev ua haujlwm nrog, uas tuaj yeem ua rau cov nqi ntau lawm hauv qee qhov kev siv.
Xaus
Hauv kev xaus, aramid npuag muaj ntau yam zoo, nrog rau nws lub zog, kub tsis kam, tsis kam tiv taus, hnav hnyav, thiab tshuaj lom neeg ua haujlwm. Txawm li cas los xij, nws kuj muaj ntau qhov tsis zoo, xws li tus nqi siab, dej tsis zoo, qhov tsis zoo rau UV degradation, txwv tsis pub, thiab nyuaj rau kev txiav thiab xaws. Thaum xaiv cov khoom siv rau ib daim ntawv thov tshwj xeeb, nws yog ib qho tseem ceeb uas yuav tau xav txog txhua yam ntawm cov khoom no thiab hnyav rau cov txiaj ntsig ntawm aramid ntaub. Txawm hais tias nws yuav yog qhov kev xaiv zoo tshaj plaws rau qee yam kev siv, nws yuav tsis yog qhov kev xaiv zoo tshaj plaws rau lwm tus.
