Kev cuam tshuam ntawm ntau yam khoom ntawm Electrothermal Tube Electroplating Da dej ntawm qhov zoo ntawm txheej

Kev cuam tshuam ntawm ntau yam khoom ntawm Electrothermal Tube Electroplating Da dej ntawm qhov zoo ntawm txheej

1) Cov nyhuv ntawm tooj liab sulfate cov ntsiab lus ntawm txheej. Raws li cov ntsev tseem ceeb hauv cov tshuaj tooj liab plating, kev hloov pauv ntawm tooj liab sulfate cov ntsiab lus muaj feem cuam tshuam rau txheej txheej [7-8]. Cov txiaj ntsig kev sim tau txais los ntawm kev hloov cov concentration ntawm tooj liab sulfate thiab kuaj pom cov tsos thiab tuab ntawm cov txheej txheem thaum ua kom lwm cov khoom tsis hloov pauv yog qhia hauv Table 1. Los ntawm Table 1, nws tuaj yeem pom tias cov thickness ntawm tooj liab txheej yog linearly ntsig txog. Lub concentration ntawm tooj liab sulfate nyob rau hauv lub plating tov, tab sis qhov zoo thiab xim ntawm tooj liab txheej txo nrog qhov nce ntawm tooj liab sulfate concentration nyob rau hauv lub plating tov. Yog vim li cas yog qhov concentration ntawm dawb tooj liab ions nce nrog tag nrho cov concentration ntawm tooj liab ions nyob rau hauv cov tshuaj plating, yog li ua rau cov tshuaj tiv thaiv ntawm sab kev xav. Raws li cov tshuaj tiv thaiv sab nrauv zuj zus, Cu2O thiab Cu tau tsim tawm hauv cov tshuaj plating, tsim cov catalytic core rau spontaneous decomposition, uas ua rau cov tshuaj plating decompose thiab thaum kawg ua rau cov txheej txheem tsis zoo [9].

2) Kev tshawb fawb txog cov txiaj ntsig ntawm nickel sulfate cov ntsiab lus ntawm lub txheej qhia tau hais tias [10], thaum nickel ions ntxiv rau cov tshuaj plating, ib qho me me ntawm cov hlau Ni thiab Cu yuav tsim co deposition. Lub co deposition ntawm Ni tuaj yeem catalyze oxidation ntawm sodium hypophosphite, yog li ua rau cov tshuaj tiv thaiv tsis tu ncua hauv tshuaj tooj liab plating. Cov kev sim hauv qab no tau ua los tshawb xyuas cov txiaj ntsig ntawm cov nickel ions ntawm qhov zoo ntawm cov txheej, thiab cov txiaj ntsig tau pom nyob rau hauv Table 2.

Los ntawm Table 2, nws tuaj yeem pom tau tias thaum qhov concentration ntawm npib tsib xee sulfate nce, qhov kev sib khi txo qis heev. Vim lub plating ceev ceev, cov tooj liab txheej sai sai tso rau saum npoo ntawm cov ntawv hlau; Cov txiaj ntsig kev sim kuj qhia tau tias qhov tsis tshua muaj siab ntawm npib tsib xee sulfate hauv cov tshuaj plating tuaj yeem ua rau cov tshuaj tiv thaiv tooj liab plating kom nres ib nrab [11]. Yog li ntawd, txhawm rau kom ntseeg tau tias qee qhov tooj liab plating tus nqi thiab qhov zoo nkauj ntawm cov yeeb yaj kiab tooj liab, qhov concentration ntawm npib tsib xee sulfate hauv cov tshuaj plating yuav tsum tau tswj ntawm ib ncig ntawm 0.6g / L.

3) Cov nyhuv ntawm Sodium Hypophosphate Cov ntsiab lus ntawm cov txheej txheem kev sim ntawm Sodium Hypophosphate ua tus neeg sawv cev txo qis hauv Electroless Copper Plating
