Yuav ua li cas thiaj ua tau ib qho hluav taws xob cua sov raj kom tau ib txheej txheej?

Yuav ua li cas thiaj ua tau ib qho hluav taws xob cua sov raj kom tau ib txheej txheej?

Teb: Cov txheej txheem kom tau txais cov txheej txheem sib xws, ntxiv rau kev xaiv cov tshuaj tsim nyog muaj pes tsawg leeg thiab txhim kho cov qauv, kev ua haujlwm tsim nyog, dai qhov chaw, thiab siv qee qhov kev ntsuas tshwj xeeb, tseem ceeb heev hauv kev tsim khoom. Cov kev siv feem ntau yog: ① cuam tshuam tam sim no: Lub sij hawm luv luv cuam tshuam electroplating nrog cov tam sim no loj (2-3 zaus siab dua li tam sim no) thaum pib electroplating. ② Tsim nyog rau nruab thiab dai qhov chaw: khaws cov khoom nyob rau hauv qhov zoo tshaj plaws tam sim no faib lub xeev, thaum tsis pub cov roj tso tawm kom stagnate nyob rau hauv lub qhov muag tsis pom qhov thiab qhov chaw qis ntawm qhov chaw Kho qhov kev ncua deb ntawm cathode thiab anode kom ntau li ntau tau. txo qhov kev ncua deb ntawm qhov sib txawv ntawm cov cathode (piv txwv li qhov concave thiab convex ntawm cov khoom) thiab cov anode. ④ Siv "pictorial" anodes los txhim kho kev faib tawm tam sim no. ⑤ Siv kev tiv thaiv cathodic thiab tiv thaiv kev tiv thaiv kom txo tau qhov ceev tam sim no hauv cov cheeb tsam ntawm cov kab hluav taws xob.

64. Dab tsi yog qhov auxiliary anode?

Teb: Nyob rau hauv cov txheej txheem ntawm electroplating ntau yam khoom thiab qhov chaw, ib co tubular qhov chaw nrog complex cov duab uas yuav tsum tau uniform txheej los yog lub puab qhov uas yuav tsum tau txheej yuav tsum tau ntxiv nrog anodes nyob rau hauv lub low-density cheeb tsam los xyuas kom meej uniform faib ntawm tam sim no ntau npaum li cas. Qhov no ntxiv anode yog hu ua auxiliary anode. Piv txwv li, siv hlau pab anodes rau galvanized puab qhov ntawm cov kav dej.

65. Kev tiv thaiv cathode yog dab tsi?

Teb: Hauv electroplating, rau qee hom plating nrog nqaim cathode tam sim no kev khiav hauj lwm ntau lossis qhov chaw nrog cov duab nyuaj, txhawm rau tiv thaiv kev kub hnyiab, cov hlau tiv thaiv hlau yog welded (los yog dai) ntawm qhov kawg ntawm qhov chaw lossis ob qho kawg ntawm plating. da dej cathode kom disperse tam sim no ntawm lub cathode. Hom hlau tiv thaiv hlau no yog hu ua cathode tiv thaiv.
