Cov yam ntxwv kev siv ntawm cov ris-resistant pob ntaub yog suav nrog hnav tsis kam, corrosion tsis kam thiab kub ua rau thiab muaj zog siab.
Hnav Tsis kam
Hnav cov ntaub ntawv tiv thaiv feem ntau yog ua los ntawm cov ntaub ntawv hardness loj, xws li ceramics, centundum, thiab muaj peev xwm tiv taus kev cuam tshuam ntau yam thiab hnav. Piv txwv li, ceramic hnav cov hnab roj-resistant feem ntau yog ua rau muaj kev ua tau zoo sib xws
Corundum hnav cov roj-resistant yog ua los ntawm txhuas oxide (corundum), uas muaj lub hardness nkaus xwb rau pob zeb diamond thiab tuaj yeem txo cov khoom poob thaum lub sijhawm ua haujlwm.
Corrosion Kuj
Hnav cov ntaub ntawv tiv thaiv cov ntaub ntawv muaj zoo corrosion tsis kam thiab tuaj yeem siv rau lub sijhawm ntev hauv cov acidic lossis alkaline ib puag ncig. Cov ntaub ntawv muaj tej yam muaj tej yam muaj cov ntaub ntawv muaj feem ntau thiab tuaj yeem tiv thaiv corrosion los ntawm ntau hom acids, alkalis, ntsev thiab lwm yam tshuaj.
Corundum cov ris tsho-resistant cov hnab looj tes tseem ua tau zoo thiab tuaj yeem tiv thaiv kev ntxig ntawm ntau yam tshuaj, haum rau tshuaj, tshuaj thiab lwm yam kev lag luam thiab lwm yam khoom lag luam.
Cov Kub Kub Kuj
Hnav cov ntaub ntawv tiv thaiv cov khoom siv zoo nyob hauv ib puag ncig kub. Cov ntaub ntawv muaj tej hub muaj cov dej num kub ruaj khov thiab tuaj yeem ua haujlwm stabably rau lub sijhawm ntev rau hauv qhov chaw kub.
Corundum hnav cov hnab looj tes tiv thaiv cov txheej txheem zoo thiab tuaj yeem tswj cov txheej txheem zoo thermal thiab muaj rau metallurgy, mining thiab lwm yam kev lag luam.
Siab Zog
Hnav cov ntaub ntawv tiv thaiv feem ntau yog ua los ntawm cov khoom siv high-zog xws li hlau lossis ceramics, thiab tuaj yeem ruaj khov nyob rau hauv ib puag ncig muaj kev kub siab thiab kub.
