Vim li cas hluav taws xob cua sov raj npua hlau castings nyuaj rau electroplate dua li lwm yam hlau?

Vim li cas hluav taws xob cua sov raj npua hlau castings nyuaj rau electroplate dua li lwm yam hlau?

Dab tsi yog qhov kev xav tau zoo tshaj plaws rau cov khoom plated ua ntej electroplating?

Teb: Ua ntej electroplating, cov khoom plated yuav tsum tsis muaj oxide ntawm daim tawv nqaij, xeb, stains, thiab roj stains, thiab qhov saum npoo tuaj yeem ntub dej tsis muaj dej.

Vim li cas kuv thiaj yuav tsum tau yaug qhov chaw nrog dej huv tom qab electroplating?

Teb: Vim hais tias tom qab cov khoom yog electroplated thiab tawm ntawm lub tank, muaj ib tug loj npaum li cas ntawm plating tov adhered rau saum npoo thiab qhov, thiab cov plating tov nws tus kheej feem ntau muaj ib tug tej yam kev mob ntawm corrosiveness. Yog tias tsis tau ntxuav kom huv si, nws yuav corrode txheej thiab substrate, cuam tshuam rau cov tsos thiab kev tiv thaiv kev ua haujlwm ntawm cov khoom. Yog li ntawd, tom qab cov plated seem tau tawm ntawm lub tank, lawv yuav tsum tau yaug tam sim ntawd nrog dej huv thiab ces qhuav.

31. Vim li cas npua hlau castings nyuaj rau electroplate dua li lwm yam hlau?

Teb: Qhov saum npoo ntawm cam khwb cia hlau feem ntau tsis sib xws thiab ntxeem tau, thiab tsuas yog cov txheej ntxhib thiab ntxeem tau yuav tau txais ntawm qhov chaw zoo li no. Tsis tas li ntawd, tseem muaj cov graphite dawb nyob rau saum npoo ntawm npua hlau, uas tsis tsuas yog cuam tshuam rau kev sib txuas ntawm cov txheej thiab cov hlau hauv paus, tab sis kuj dhau los ua cov cathode ntawm cov roj teeb corrosion thaum muaj qhov pores hauv txheej, ua rau muaj kev puas tsuaj sai. txheej hlau. Cov graphite hauv npua hlau qee zaum muaj cov txiaj ntsig ntawm kev txo qis hydrogen overvoltage, ua rau hydrogen yooj yim los nag thiab cuam tshuam cov hlau deposition. Yog li ntawd, Cast npua hlau qhov chaw yog qhov nyuaj rau electroplate dua li lwm yam hlau.
