Thaum xaiv cov khau kev nyab xeeb, tus taw yog ib feem uas feem ntau tau dhau tab sis yog qhov tseeb ntawm qhov tseem ceeb tshaj plaws. Lub tiby yog ib feem ntawm cov khau uas tau nkag mus rau hauv av, thiab nws cov khoom siv ncaj qha cuam tshuam rau kev ua haujlwm thiab kev nplij siab ntawm khau. Cov khau khau uas muaj kev nyab xeeb niaj hnub ua los ntawm cov ntaub ntawv hauv qab no: Polyurethane (PiToplastic Polyurethane (TPU), thiab roj hmab. Nyob rau hauv lub xyoo dhau los 90s, polyvinyl chloride (PVC) yog ib zaug nrov, tab sis nws yog tam sim no kuj tsis tshua muaj.
Polyurethane Tib
Polyurethane yog cov feem ntau siv cov khoom siv ntawm cov khau kev nyab xeeb. Nws tuaj yeem nyob hauv ib qho - ntom lossis ob npaug - qhov qauv ua si. Ob npaug {{4 {}}} qhov ceev polyurethane soles tau dhau los ua tus qauv thoob ntiaj teb thiab muab cov midsole ntev. Cov outsole yog lub luag hauj lwm rau kev tawm tsam cov av cuam tshuam, thaum lub nruab nrab muab cov cushioning zoo. Polyurethane soles muaj cov yam ntxwv ntawm kev hloov pauv, lub teeb pom kev zoo, roj thiab acid tsis kam, kub tsis kam, thiab kuj siv tau ntawm tus nqi.
Thermoplastic Polyurethane Tib
Thermoplastic polyurethane yog cov neeg tshwj xeeb khau cov khoom siv. Txawm hais tias nws yooj yim me ntsis qis dua rau lub polyurethane, nws tseem muaj cov yam ntxwv ntawm kev ua kom muaj roj acids, nplua {{free {tiv taus. Qhov tseem ceeb tshaj plaws yog nws cov kev txiav zoo heev. Vim nws cov kws tshaj lij, tus nqi yog siab dua.
Roj hmab nkaus
Cov roj hmab pawg tau koob meej rau lawv lub durability thiab haum rau siv nyob rau hauv ib puag ncig ib puag ncig xws li kev tsim kho, engineering, thiab mining. Lawv muaj cov khoom siv nyuaj uas muaj kev tiv thaiv zoo heev rau kev txiav thiab hno, nrog rau kev ua siab ntev rau qee yam tshuaj muaj zog. Cov roj hmab ib leeg tuaj yeem tiv thaiv kub txog li 300 degrees thiab tsis haum, ua rau lawv haum, tsis muaj txias}
Xaiv cov khoom siv uas tsim nyog yog ib kauj ruam tseem ceeb hauv kev ua kom cov khau kev nyab xeeb tuaj yeem muab kev tiv thaiv zoo tshaj plaws thiab kev nplij siab zoo tshaj plaws. Polyurethane yog tsim nyog rau cov uas nrhiav kev xaiv nyiaj txiag thiab ntau yam; Thermoplastic polyurethane yog tsim nyog rau cov kws tshaj lij ib puag ncig cov; Thiab roj hmab yog qhov kev xaiv zoo tshaj plaws rau huab. Raws li cov kev cai tshwj xeeb ntawm ib puag ncig ua haujlwm, xaiv cov khoom ua haujlwm tshaj plaws tuaj yeem ua kom cov khau kev nyab xeeb muab cov txiaj ntsig siab tshaj thaum siv.
