Hauv cov tsev sib txawv, txawvdaim ntawv tooj dagcov khoom siv tau, xws li tooj liab oxide phaj.Thaum siv, nws yuav tsim ib lub ntsej muag xim av thiab ua kom zoo dua qub.Tsis tas li ntawd, cov phaj tooj liab kuj tuaj yeem siv rau hauv kev kho dua tshiab ntawm ntau lub tsev qub, lossis qee lub tsev uas yuav tsum tau tshwj xeeb.Lub phaj tooj dag saum npoo yuav muaj cov xim hlau nplaum, thiab yuav maj mam hloov, thaum siv, yuav ua rau lub tsev zoo dua qub.
Tsis tas li ntawd, cov ntawv tooj dag muaj lub zog ua haujlwm siab, tab sis qhov elongation yog inversely proportional rau lub zog.Yog tias koj xav nce lossis txo qhov nyuaj ntawm cov phaj tooj liab, koj tuaj yeem kho cov phaj tooj liab los ntawm kev kho cua sov.Tooj liab yog ib yam khoom uas muaj ductility zoo, yog li nws yooj yim heev thiab haum rau kev siv ntawm kev tsim kho kev lag luam, nrog rau qhov zoo.Kev siv cov phaj tooj liab, tsis txwv los ntawm qhov kub thiab txias, txawm tias nyob rau hauv ib puag ncig uas tsis muaj qhov kub thiab txias, yuav tsis muaj qhov xwm txheej, ntawm qhov kub melting point, koj tuaj yeem siv kub yaj vuam los ua cov txheej txheem.
Cov ntawv tooj dag kuj yog qhov ua tau zoo heev ntawm hluav taws, yog cov khoom tsis muaj hluav taws kub.Hauv qee qhov chaw muaj corrosive heev, cov phaj tooj liab yuav tsim cov txheej txheem tiv thaiv tsis muaj tshuaj lom rau ntawm qhov chaw, uas yog qhov peb hu ua patina.Patina tuaj yeem ua qhov kev tiv thaiv zoo ntawm cov phaj tooj liab, thiab, thaum puas lawm, nws tuaj yeem kho tau.
Muaj ntau tus pas nrig tooj dag, tooj dag band, tooj dag daim ntawv hauv lub neej, vim tias nws yog ib hom kev ruaj ntseg zoo, thiab tsis tshua muaj txij nkawm tus nqi ntawm lub ru tsev thiab kab hlau rhuav phab ntsa siv dav hauv cov ntaub ntawv.Nws muaj kev tiv thaiv ib puag ncig thiab kev nyab xeeb, thiab muaj kev tiv thaiv corrosion zoo.
