Cov Khoom Siv Kev Nyab Xeeb: Qhov tseem ceeb tshaj plaws
Thaum nws los txog rau txoj kev nyab xeeb siv kev nyab xeeb, xaiv cov khoom zoo yog qhov tseem ceeb. Txoj siv sia kev nyab xeeb yog lub luag haujlwm tiv thaiv cov tsav tsheb thiab cov neeg caij tsheb thaum muaj kev sib tsoo, yog li cov khoom yuav tsum muaj zog thiab ruaj khov txaus los tiv thaiv cov neeg cuam tshuam.
Lub zog thiab lub zog
Qhov tseem ceeb tshaj plaws los txiav txim siab thaum xaiv cov khoom siv kev nyab xeeb yog lub zog thiab kav ntev. Cov ntaub ntawv yuav tsum muaj lub zog tensile siab, uas txhais tau tias nws tuaj yeem tiv thaiv tau rub tawm ntawm qhov hnyav ntawm qhov hnyav tsis muaj kev sib tsoo lossis ncab. Ib qho ntxiv, cov ntaub ntawv yuav tsum muaj cov khoom siv ruaj khov uas tso cai rau nws kom tiv thaiv qhov cuam tshuam ntawm kev raug rau lub hnub thiab lwm cov khoom ib puag ncig.
Nylon
Nylon yog cov khoom siv feem ntau siv hauv kev siv hluav taws xob kev nyab xeeb. Cov khoom siv no muaj lub zog siab thiab cov khoom siv tsis tau muaj zog uas ua rau nws zoo rau kev siv nyob rau hauv txoj siv kev nyab xeeb. Nylon kuj tseem tiv taus kev puas tsuaj thiab tuaj yeem tiv thaiv kom raug rau cov tshuaj thiab roj. Qhov tseem ceeb tshaj plaws, Nylon muaj cov zog nqus tau zoo thiab muaj peev xwm muaj qhov cuam tshuam ntawm kev sib tsoo.
Polyester
Polyester yog lwm qhov kev xaiv nrov rau cov khoom siv kev nyab xeeb. Cov khoom siv no muaj lub zog siab muaj zog thiab muaj kev tiv thaiv kom ncab ncab thiab tawg. Polyester tseem tiv taus hnav thiab kua muag, uas ua rau nws xaiv zoo rau kev siv hauv kev tiv thaiv kev nyab xeeb. Ib qho ntxiv, Polyester yog lub teeb ci, uas txhais tau tias nws tuaj yeem ua kom muaj zog li nylon thaum hnyav tsawg dua.
Txoj hlua muag
Kevlar yog cov hluavtaws fiber uas feem ntau siv hauv cov ntawv thov kev ua haujlwm zoo xws li siv tawv thiab cov ntawv cog tseg. Cov khoom siv no muaj lub zog siab thiab cov yam ntxwv tsis txaus ntseeg thiab tiv taus kom muaj kev kub thiab tshuaj lom neeg ntau. Nws muab lub zog nqus tau zoo heev thiab muaj peev xwm los nrog nrog cov kev cuam tshuam ntawm kev sib tsoo.
Hlau
Cov hlau yog qhov tsis tshua muaj txaus tab sis tseem muaj txiaj ntsig zoo rau kev siv nyob rau hauv txoj siv sia kev nyab xeeb. Hlau muab lub zog siab thiab cov kev ua kom ruaj khov thiab tiv taus hnav thiab kua muag. Txawm li cas los xij, cov hlau yog qhov hloov tau tsawg dua li lwm cov ntaub ntawv uas yuav txwv nws siv hauv qee cov ntawv thov.
