Kuv yuav ua li cas yog tias cov tshuaj plating dhau los ua huab thiab tsis pom lawm?
Nws tuaj yeem yog qhov pH siab dhau, ua rau zinc ion hydrolysis. Acid yuav tsum tau ntxiv los kho cov pH.
Ntau dhau impurities yuav tsum tau pom los yog electrolytic purification.
Dab tsi ua rau cov pob dawb tshwm rau ntawm cov yeeb yaj kiab passivation lossis nws poob?
Kev tu tsis tiav ua ntej passivation tuaj yeem ua rau cov khoom seem plating los ua cov tshuaj passivation.
Lub sij hawm passivation luv dhau los yog cov kua passivation concentration tsis txaus; ncua lub sij hawm los yog ntxiv cov reagents.
Kuv yuav ua li cas yog tias lub thickness ntawm txheej tsis sib npaug thiab sib txawv heev?
Kho lub hanger kom ntseeg tau tias txawm tias tam sim no faib thoob plaws ib feem.
Xyuas seb cov txheej txheem plating puas tau nplawm thiab ntxiv cov stirrer yog tias tsim nyog.
Dab tsi ua rau muaj ntau cov npuas thiab cov txheej xoob thaum lub sij hawm electrolysis?
Kev ceev tam sim no ntau dhau yuav ua rau muaj ntau cov hydrogen ions tso tawm ntawm cathode (hydrogen evolution cov tshuaj tiv thaiv).
Lub hydrogen ion concentration hauv cov tshuaj plating yog siab dhau (pH tsawg dhau); ntxiv alkali los kho cov pH.
Kuv yuav ua li cas yog tias cov txheej txheej muaj "streaks" lossis "mottling"?
Cov additive piv yog unbalanced; cov concentrations ntawm brightener thiab debonding tus neeg sawv cev yuav tsum tau kuaj thiab kho.
Tom qab- kev kho tu tsis huv, tawm hauv cov kua qaub/alkali, yuav tsum tau kho kom zoo dua qub.
