Hauv kev lag luam hlau, tooj liab yog cov khoom siv dav siv vim nws zoo heev conductivity, thermal conductivity, thiab ductility.Txawm li cas los xij, tooj liab yog nquag oxidation nyob rau hauv cov huab cua, tsim ib tug nyias oxide zaj duab xis uas ua rau ib tug txo nyob rau hauv kev ua tau zoo.Txhawm rau txhim kho cov khoom tiv thaiv oxidation ntawm tooj liab, ntau txoj hauv kev tau ua haujlwm, ntawm cov kev siv tooj liab passivation tov ua pov thawj tias yog kev daws teeb meem zoo.Kab lus no yuav piav qhia txog cov txheej txheem ntawm tooj liab antioxidation siv tooj liab passivation tov.
I. Cov Ntsiab Cai ntawm Copper Passivation Solution
Copper passivation solution yog cov tshuaj kho mob uas tsim cov oxide zaj duab xis ruaj khov ntawm cov tooj liab, tiv thaiv kev sib cuag ntawm tooj liab thiab oxygen, yog li ua tiav cov tshuaj tiv thaiv oxidation.
II.Cov txheej txheem ntawm Copper Antioxidation
Ntxuav: Pib los ntawm kev ntxuav cov tooj liab kom tshem tawm cov impurities xws li roj thiab plua plav, kom ntseeg tau tias cov tshuaj passivation tuaj yeem tiv tauj tag nrho cov tooj liab.
Soaking: Muab cov tooj liab ntxuav hauv cov tshuaj passivation, feem ntau yuav tsum tau 3-5 feeb rau cov tshuaj kom nkag mus rau hauv cov tooj liab.Tswj kub thiab lub sij hawm thaum soaking kom tsis txhob muaj qhov zoo tshaj plaws oxidation los ntawm kev ua haujlwm sai lossis qeeb.
Rinsing: Muab cov hlau lim hauv cov dej huv kom yaug tawm cov kua dej uas seem thiab cov impurities.Thaum lub sij hawm yaug, saib seb qhov tooj liab puas huv si, thiab rov ua cov txheej txheem yog tias tsim nyog.
Kev ziab kom qhuav: Cia cov tooj liab rinsed kom cua qhuav hauv qhov chaw uas muaj cua zoo lossis siv qhov cub kom qhuav.
Kev tshuaj xyuas: Ua cov tshuaj tiv thaiv oxidation kev ua tau zoo ntawm cov tooj liab qhuav.
III.Cov kev ceev faj
Ua raws li cov lus qhia nruj me ntsis thaum npaj cov tshuaj passivation kom tsis txhob muaj ntau dhau lossis tsis txaus cuam tshuam rau kev kho mob.
Khaws qhov ntsuas kub ruaj khov thaum lub sij hawm ntub dej kom tsis txhob muaj kev hloov pauv uas tuaj yeem ua rau tsis zoo oxide zaj duab xis.
Tsis txhob khawb qhov tooj liab thaum lub sij hawm ntxuav thiab yaug kom tsis txhob muaj kev cuam tshuam rau kev ua haujlwm zoo.
