Copper yog ib qho khoom siv hlau uas muaj qhov zoo txuas ntxiv thiab siab thermal thiab hluav taws xob conductivity. Raws li nws muaj pes tsawg leeg, nws tuaj yeem pom plaub xim sib txawv ntawm ntshav, daj, ntsuab thiab dawb nyob rau hauv tsos, uas yog qhov peb hu ua liab tooj liab, tooj dag, tooj liab thiab dawb tooj liab. Hauv lub neej thiab kev tsim khoom, tooj liab kuj muaj nyob txhua qhov chaw.
Hom Xim Xim ntawm Tooj Liab
Muaj plaub lub ntsiab xim ntawm tooj liab hauv peb lub neej niaj hnub:
Tooj
Hais txog tooj liab ntshiab, tseem hu ua liab tooj liab, muaj npe rau nws cov xim liab. Liab tooj liab feem ntau hu ua liab tooj liab vim nws cov xim liab liab thiab xim liab tom qab ib zaj duab xis oxide yog tsim rau ntawm qhov chaw. Liab tooj liab yog tooj liab uas muaj qee yam ntawm cov pa oxygen, yog li nws tseem hu ua oxygen-muaj tooj liab.
tooj dag
Brass yog ib qho alloy uas muaj tooj liab thiab zinc. Brass uas muaj tooj liab thiab zinc hu ua tooj dag zoo tib yam. Yog tias nws yog ntau yam alloys uas muaj ob lossis ntau lub ntsiab lus, nws yog hu ua tooj dag tshwj xeeb.
Bronze
Bronze yog qhov ntxov tshaj plaws alloy nyob rau hauv keeb kwm ntawm hlau smelting. Lub alloy ntawm tin los yog txhuas ntxiv rau cov tooj liab ntshiab muaj qhov tseem ceeb tshwj xeeb thiab keeb kwm tseem ceeb.
Dawb tooj liab
Cupronickel yog tooj liab-raws li alloy nrog npib tsib xee ua lub ntsiab additive. Nws yog nyiaj-dawb thiab muaj xim hlau luster, yog li nws yog hu ua cupronickel.
Ntxiv rau qhov saum toj no plaub hom xim ntawm tooj liab, tooj liab tuaj yeem tsim ib txheej ntawm ntsuab tooj liab carbonate rau saum npoo ntawm tooj liab nyob rau hauv cov huab cua ntub, thiab cov xim liab pom patina tuaj yeem tsim nyob rau saum npoo ntawm qee qhov kev cai qub. tooj liab oxide yog xim dub; anhydrous tooj liab sulfate yog hmoov dawb; tooj liab sulfate yog ntuj xiav.
