Cov raj tooj dag tseem tseem muaj nyob hauv lub neej niaj hnub niaj hnub no, thiab nws yuav siv ntau qhov chaw. Tab sis txawm nrog xws li ib yam khoom, tseem muaj ntau tus neeg uas tsis to taub nws cov yam ntxwv kev ua tau zoo. Yog li, dab tsi yog qhov kev ua tau zoo ntawm cov khoom no? Cov hauv qab no yog cov lus qhia luv luv rau kab lus no.
Ua ntej tshaj plaws, cov yeeb nkab tooj dag yog cov yeeb nkab uas tsis yog hlau uas feem ntau siv tau los ua cov kav dej. Vim tias cov khoom siv yeeb nkab no yog cov khoom siv seamless, nws tuaj yeem tiv thaiv cov yeeb nkab dej kom zoo. Tau kawg, vim tias cov khoom siv tooj liab no muaj lawv tus kheej hardness kuj thiab zoo corrosion kuj, nws kuj siv tau los ua cua sov thiab cua txias kav.
Cov yeeb nkab tooj dag tsis tsuas yog muaj qhov zoo corrosion kuj thiab cov khoom tawv, tab sis kuj muaj zog plasticity. Piv nrog rau lwm cov khoom siv hlau, cov yeeb nkab zoo li no muaj cov yam ntxwv ntawm kev khoov, thim rov qab thiab tsis yooj yim rau kev tawg. Cov khoom siv raj no tau siv dav hauv lub neej txhua hnub thiab muaj lub neej ua haujlwm ntev dua.
Cov yeeb nkab tooj dag muaj qhov muaj zog te heave tsis kam thiab cuam tshuam tsis kam. Cov khoom siv tooj liab nrog cov txiaj ntsig zoo no muaj lub neej ua haujlwm ntev thiab tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv dej. Cias muab tso, tsuav yog cov khoom siv tooj liab yeeb nkab no tau teeb tsa, nws muaj cov yam ntxwv ntawm kev nyab xeeb thiab kev ntseeg tau, thiab txawm tias tsis tas yuav tsum tau saib xyuas thiab tu.
