Cov yam tseem ceeb cuam tshuam rau qhov zoo ntawm qhov chawtooj liabyog cov txheej txheem tsim khoom, thiab dhau los ntawm tag nrho cov txheej txheem tsim khoom, muaj cov laj thawj hauv qab no rau oxidation ntawm tooj liab sawb:
1. Lub sij hawm ua ntej ziab yog ntev heev.
2. Acid -corrosive tooj liab los xij ua tom qab tus neeg sawv cev kho.
3. Copper yog ib qho khoom siv hlau, uas yooj yim rau plam electrons thiab tsim oxidation.
4. Tsis tas li ntawd, atmospheric humidity, deg pollution, impurities gas, thiab lwm yam kuj tuaj yeem ua rau tooj liab ore oxidation.
5. Cov kab liab tooj liab tau raug ntxuav kom huv si ua ntej nyiaj plating, thiab qhov saum npoo tau pom cov cim dub.Nws yog ib qho sub-salt uas ua los ntawm oxidation thiab poob ntawm hluav taws xob.
6. Tom qab ntxuav, nws tsis qhuav nyob rau hauv lub sij hawm, kom qhuav, los yog tsis zoo craftsmanship.Cov dej uas seem tshuav, ntxuav cov kua dej, thiab lwm yam muaj cov tshuaj tiv thaiv electrochemical nrog cov pa oxygen hauv huab cua thiab cov pa oxygen hauv huab cua.Dub sub-copper yog generated, thiab nws yog ntsuab ntsev nyob rau hauv mob hnyav.
Txoj kev:
1. Txhim kho cov roj inert thaum lub sij hawm tiv thaiv thermal.Vim tias cov khoom siv tshuaj lom neeg ntawm tooj liab muaj zog heev, ntawm qhov kub thiab txias thiab kev kho cua sov, lawv tuaj yeem muaj cov tshuaj tiv thaiv sai nrog cov pa roj ntau nyob hauv huab cua.Yog li ntawd, nws yog ib qho tsim nyog los tiv thaiv cov roj inert nyob rau hauv nws muaj zog dua thiab tiv thaiv tooj liab los ntawm oxidized.
2. Ua kom muaj zog ntawm kev ntxuav ntawm qhov chaw ntawm lub nplhaib tooj liab kom tswj tau cov qib siab ntawm smoothness.Nyob rau hauv dov dov thiab annealing txheej txheem, qhov saum npoo ntawm tooj liab strip yuav inevitably tsim oxides rau vaj tse, thiab ntxuav, tso tseg, passivation thiab lwm yam kev tu.
3. Txhim khu kev tswj cov txheej txheem ntau lawm.Ntxuav cov impurities ntawm lub ntsej muag tooj liab nrog cov plaub hau txhuam thiab dej, thiab qhwv lub sawb tooj liab nrog cov ntawv hauv ob sab phlu ua ntej dov los tiv thaiv qhov chaw los ntawm khawb.Tsis tas li ntawd, tag nrho cov roj dov txoj kev yog saws los hloov cov khoom siv roj ntawm lub tshuab dov, thiab ua kom qeeb ntawm dov ceev, thiab siv txhua txoj hauv kev kom tshem tawm cov pa phem tawm ntawm qhov chaw ntawm cov tooj liab.Nyob rau tib lub sijhawm, peb cov neeg ua haujlwm tsim khoom tau ntxiv dag zog rau kev tswj hwm kev tsim khoom thiab kev saib xyuas ntxiv.
4. Txhim kho qhov ntim kawg ntawm kev tswj cov khoom tiav.Copper strips yuav tsum tau qhuav tom qab pickling.Cov av noo ib puag ncig yuav ua rau kom qhov corrosion ntawm tooj liab thiab cuam tshuam rau qhov tseeb ntawm cov khoom tiav.Yog li ntawd, txhawm rau kom ntseeg tau tias qhov ziab ntawm cov khoom, muab ob npaug rau kev ntsuas.Thaum cov khoom tiav qhuav li sai tau, thaum ntim, thawj cov ntaub qhwv nrog cov hnab yas, thiab tom qab ntawd qhwv nws nrog zaj duab xis dawb kom tiv thaiv cov av noo sab nraud thaum thauj.cuam tshuam.
