Tooj liabMuaj hluav taws xob zoo, thermal conductivity thiab duction, thiab lwm yam. Cov feem ntau dav siv yog tooj liab thiab tooj liab.
Tooj dag thiab liab tooj liab uas nyuaj?
1. Lub universal tus yam ntxwv ntawm cov ntaub ntawv hlau yog tias lub hardness ntawm cov neeg ntshiab hlau yog qis dua li ntawm nws alloy, uas muaj lub siab halting thiab tsawg melting point. Thiab anaerobic tooj liab thiab tooj liab dawb, tab sis lub cev tsis huv, tab sis kuj yog qhov sib txawv ntawm lub zog ntawm anaerobic) nyuaj tshaj.
2. Tooj muaj tus yam ntxwv nyuaj, yuav siv cov khoom siv cua sov, thiab tom qab ua haujlwm hnyav, yog li feem ntau muaj cov ntaub ntawv nyuaj, tsuas yog cov lus piav qhia zoo.
3. Dab tsi yog lub hardness ntawm purple tooj liab? Tooj liab, ntom ntom (7.83g / cm3) melting point 1083 degrees, tooj liab cov ntsiab lus nce mus txog 99.9%, nws tsis sib nqus. Nrog zoo hluav taws xob conduction, thermal conductivity thiab corrosion tsis kam, tooj liab yog muaj npe rau nws cov xim liab. Tooj liab muaj zoo corrosion tsis kam nyob rau hauv huab cua, hiav txwv tsis-oxidizing acid, alkali, ntsev kua thiab ntau yam organic acids. Nws yog siv hauv kev lag luam tshuaj lom neeg.
