Kev paub txog tooj liab
Copper wire yog ib qho hlau hlau uas tau txais los ntawm kub dov tooj liab rods. Nws muaj cov khoom siv hluav taws xob zoo, thermal conductivity thiab ductility, nrog rau cov khoom siv zoo heev thiab vuam yooj yim. Hom tooj liab hlau muaj xws li tooj dag, tooj liab thiab phosphor tooj liab. tooj dag hlau muaj 65% tooj liab thiab 35% zinc, tooj liab hlau muaj purity txog li 99.8%, thiab phosphor tooj liab hlau muaj 85% -90% tooj liab thiab 5% -15% tin. Copper hlau yog dav siv, suav nrog tab sis tsis txwv rau weaving nets, cables, tooj liab txhuam cov ntxaij lim dej, thiab lwm yam. Tsis tas li ntawd, tooj liab hlau kuj tseem siv rau hauv kev lag luam pom, petrochemicals, luam ntawv, hlau thiab hluav taws xob kho vajtse qhov chaw ua, txias rivets thiab screws. , avionics accessories thiab telecommunications li, connector riveting kev ua tau zoo, decorations, embedded nuv ntses kab, thiab lwm yam. Vim nws zoo heev hluav taws xob conductivity, tooj liab hlau kuj yog feem ntau siv raws li ib tug neeg xyuas pib. Txawm hais tias nyiaj muaj zog conductivity, tooj liab hlau yog dav siv vim nws cov nqi qis.
Nyob rau hauv cov txheej txheem ntawm tooj liab hlau, hlau kos duab yog ib qho tseem ceeb txuas, nrog rau ntau yam txheej txheem, xws li softening (annealing), pwm xaiv, thiab siv cov hlau kos duab roj, los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm tooj liab hlau. Cov txheej txheem kos duab hlau tsis yog tsuas yog xaiv cov khoom siv tooj liab xwb, tab sis kuj suav nrog kev xaiv thiab siv cov khoom siv, pwm, thiab cov hlau kos cov roj kom ntseeg tau tias cov khoom siv tooj liab ua tau raws li cov lus qhia tshwj xeeb.
Tsis tas li ntawd, tooj liab hlau tuaj yeem ua tiav raws li nws cov kev siv thiab kev ua haujlwm, xws li ua cov hlau enameled, uas yog, txheej txheej ntawm tooj liab hlau nrog insulating xim, cua sov thiab ziab, thiab siv los tsim kev sib txuas lus thiab fais fab cables, hluav taws xob machinery, thiab ntau yam khoom siv hauv tsev. Kev siv dav ntawm tooj liab hlau thiab nws txoj kev koom tes rau tib neeg kev vam meej qhia txog tus nqi tseem ceeb ntawm tooj liab raws li ib qho ntawm cov hlau ntxov tshaj plaws uas tib neeg pom.
