Nyob rau hauv lub ntiaj teb ntawm khau raj tsim,Thawj Tswjhwm SaibCov txheej thiab cov ntaub txheej txheej cov ntaub ntawv yog ob qho tseem ceeb ntawm cov txheej txheem ntau lawm. Txawm li cas los xij, ob qho tib si siv nyob rau hauv kev tsim khau, muaj cov sib txawv ntawm ob cov khoom no. Nkag siab txog cov kev sib txawv ntawm cov txheej txheem tswj hwm hluav taws xob thiab cov ntaub txheej txheej khoom yog qhov tseem ceeb rau khau tsim kom zoo, ruaj khov khau.

Cov tswv yim tswj hwm yog ib cov ntaub ntawv tshwj xeeb tsim rau cov insole ntawm khau. Cov ntaub ntawv no yog siv los muab kev txhawb nqa thiab cov qauv rau khau, nrog rau kom muab cov chaw zoo rau tus neeg hnav lub taw. Cov txheej txheem tswj cov txheej txheem feem ntau yog ua los ntawm ntau cov khoom siv hluavtaws, xws li polyester lossis polypropylene, thiab feem ntau yog cov txheej txheej nplaum kom ntseeg tau tias lawv ua raws li cov khau. Hauv kev sib piv, cov ntaub npuag txheej tau siv los ntawm cov ntaub sab nrauv ntawm cov khau. Cov txheej no pabcuam txhawm rau tiv thaiv cov ntaub los ntawm hnav thiab kua muag, zoo li muab cov dej-resistant barrier. Cov khoom siv cov ntaub npuag tuaj yeem ua los ntawm cov khoom siv, suav nrog polyurethane, acrylic, thiab tau thov rau cov ntaub los ntawm ntau txoj kev, xws li txau lossis laminating.

Qhov kev sib txawv ntawm kev sib txawv ntawm cov txheej txheem tswj hwm thiab cov ntaub ua cov txheej txheej nyob hauv lawv cov kev siv thiab muaj nuj nqi hauv khau. Thaum ob qho tib si cov ntaub ntawv tau siv los txhim kho qhov zoo thiab ruaj khov cov khoom siv tau tsim los muab cov ntaub ntawv qhia txog kev tiv thaiv cov ntaub sab nrauv ntawm cov khau. Cov txheej txheem txheej txheem txheej yog feem ntau thicker thiab ntau dua rigid, thaum cov khoom siv npuag tau yooj yim, tso cai rau kev txav mus los thiab yoog raws li khau.

Lwm qhov tseem ceeb sib txawv ntawm cov txheej txheem saib xyuas hluav taws xob thiab cov ntaub txheej txheej cov khoom yog daim ntawv thov cov txheej txheem. Cov txheej txheem txheej txheem txheej feem ntau yog siv thaum lub sijhawm tsim khoom, thiab feem ntau tau muab ncaj qha rau kev tsim kho khau. Hauv kev sib piv, cov ntaub npuag txheej tau thov cais rau sab nrauv cov khau, yog thaum lub sijhawm ua haujlwm tsim khoom lossis ua ib qho kev tsim khoom tom qab. Qhov kev sib txawv ntawm cov kev thov cov qauv no rau cov qauv txheej txheem ntawm cov qauv khau, thaum cov khoom ris cov khoom ua haujlwm rau txheej txheej tiv thaiv sab nraud.

Hauv kev xaus, thaum cov ntaub ntawv insole thiab cov ntaub txheej txheej yog ob qho tseem ceeb ntawm khau tsim, muaj qhov sib txawv ntawm ob. Nkag siab txog cov kev sib txawv ntawm cov ntaub ntawv no yog qhov tseem ceeb rau khau cov tuam ntxhab nrhiav kev tsim kom muaj cov khau zoo, ruaj ruaj. Los ntawm kev paub txog cov haujlwm tshwj xeeb, kev ua haujlwm, thiab cov ntaub ntawv tsim nyog ntawm cov ntaub ntawv tsim nyog rau txhua cov khau, ua rau kev tsim cov khau zoo dua.
