Kevlar webbing tau lees paub dav dav rau nws qhov tshwj xeeb txiav tsis kam thiab muaj zog tshuaj lom neeg ruaj khov, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm siab - kev ua haujlwm xws li cov cuab yeej siv tshuab, cov cuab yeej siv kev nyab xeeb, thiab hnyav - lub luag haujlwm strapping. Cov ntsiab lus ntawm nws cov kev ua tau zoo nyob rau hauv ob qhov chaw no yog raws li hauv qab no:
1. Kev txiav zoo heev
Kevlar webbing yog ib qho kev txiav ntau tshaj plaws - cov ntaub ntawv hluavtaws hluavtaws ntawm lub khw, deb tshaj cov ntaub ntawv zoo li nylon thiab polyester.
Kevlar fibers muaj qhov nruj, muaj kev taw qhia cov qauv molecular thiab muaj zog interchain bonding. Thaum raug txiav quab yuam, cov fibers tsis yooj yim shear los yog tsim kua muag; Hloov chaw, lawv faib lub zog hla tag nrho cov qauv webbing.
Nyob rau tib lub thickness, Kevlar webbing tuaj yeem tiv taus kev txiav los ntawm cov khoom ntse xws li riam, cov npoo hlau, thiab cov khoom khib nyiab uas tsis muaj kev ua haujlwm sai. Cov cuab yeej no tseem ceeb heev rau cov ntawv thov xws li cov hnab looj tes tiv thaiv, cov hlua khi kev nyab xeeb, thiab cov khoom thauj khoom thauj -downs, qhov chaw sib cuag nrog cov cuab yeej ntse yog nquag.
Durability Note:Thaum Kevlar webbing raug txiav heev - tiv taus, nws tsis yog txiav tag nrho - pov thawj. Kev sib txhuam ntev ntev tiv thaiv cov npoo tsis tshua muaj siab lossis siab -siab shearing tseem tuaj yeem ua rau hnav, yog li kev tshuaj xyuas tsis tu ncua ntawm thaj chaw muaj kev ntxhov siab yog pom zoo rau daim ntawv thov kev nyab xeeb tseem ceeb.
Kevlar webbing nthuav tawm kev ruaj ntseg tshwj xeeb thaum raug rau ntau yam tshuaj, tswj nws cov khoom siv kho mob txawm tias nyob rau hauv ib puag ncig hnyav tshuaj:
Resistant Khoom:Nws tiv taus ntau cov kuab tshuaj organic (xws li cawv, ethers, hydrocarbons), alkalis, thiab ntsev daws. Hauv cov chaw tsim khoom, kev sib cuag nrog cov neeg ua haujlwm tu, roj, lossis cov kua alkaline diluted yuav tsis ua rau fiber ntau degradation, o, los yog tsis muaj zog. Qhov no ua rau nws tsim nyog rau kev siv nyob rau hauv marine ib puag ncig, tshuaj nroj tsuag, thiab roj teb.
Kev txwv:Kevlar raug cuam tshuam los ntawm cov tshuaj muaj zog oxidizing (piv txwv li, concentrated nitric acid, sulfuric acid) thiab qee cov tshuaj halogenated. Ntev ntev raug rau cov tshuaj no tuaj yeem rhuav tshem cov fiber ntau cov saw hlau molecular, ua rau embrittlement thiab txo lub zog tensile.
Tswv yim zoo:Tsis zoo li nylon, uas tuaj yeem nqus tau cov tshuaj thiab o, Kevlar qhov nqus dej tsawg thiab tshuaj lom neeg ruaj khov ua kom muaj kev ua haujlwm zoo ib yam txawm tias nyob hauv qhov chaw ntub dej lossis cov tshuaj lom neeg. Hauv cov ntsiab lus, Kevlar webbing muaj kev txiav zoo heev thiab tshuaj lom neeg ruaj khov rau feem ntau cov xwm txheej, tshwj tsis yog qee qhov muaj zog oxidizing cov neeg ua haujlwm. Qhov kev sib xyaw ua ke ntawm cov khoom no ua rau nws tseem ceeb rau kev thov kev lag luam thiab kev nyab xeeb.
