Lub hauv paus ntsiab lus ntawm Electroforming Thiab Electroplating Processing Ntawm Nickel Signs

Nyob rau hauv cov txheej txheem ntau lawm ntawm cov cim nickel, electroforming thiab electroplating yog ob txheej txheem txheej txheem, txhua tus ntawm cov txheej txheem sib txawv.

Electroforming txheej txheem

Electroforming, tseem hu ua electrolytic casting, yog ib txoj hauv kev ua cov cim los ntawm electrolytically tso hlau rau ntawm pwm. Hauv cov txheej txheem electroforming, cov pwm pwm ua haujlwm raws li cathode, thaum lub anode feem ntau siv cov kua ntsev ntsev ntsev. Thaum tam sim no dhau los ntawm electrolyte, cov hlau ions ntawm lub anode raug txo thiab tso rau ntawm cathode (piv txwv li pwm), maj mam tsim cov duab kos npe xav tau.

Cov ntsiab lus tseem ceeb ntawm electroforming ua cov txheej txheem suav nrog:

Electrolyte: Ib qho tshuaj uas muaj nickel ntsev thiab lwm yam khoom ntxiv uas muab cov hlau ions xav tau hauv cov txheej txheem electroforming.

Tam sim no thiab voltage: Tam sim no yog muab los ntawm ib qho hluav taws xob sab nraud los tsav cov hlau ions kom txo tau thiab tso rau ntawm cathode.

Pwm: Raws li cov matrix ntawm cathode, nws cov duab txiav txim siab cov duab ntawm qhov kawg kos npe.

Kub: cuam tshuam cov conductivity thiab deposition tus nqi ntawm cov electrolyte.

Nickel kos npe electroplating ua txoj cai

Electroplating yog txheej txheem ntawm kev tso cov yeeb yaj kiab hlau nyias rau ntawm cov txheej txheem uas twb muaj lawm los ntawm electrolysis, uas yog siv los txhim kho corrosion kuj, zoo nkauj lossis lwm yam khoom ntawm substrate. Hauv kev tsim cov cim nickel, electroplating feem ntau yog siv los npog cov hlau substrate nrog ib txheej npib tsib xee.

Cov ntsiab lus tseem ceeb ntawm cov txheej txheem electroplating yog:

Electrolyte: Ib qho tshuaj uas muaj nickel ntsev thiab lwm yam khoom ntxiv uas muab cov hlau ions xav tau hauv cov txheej txheem electroplating.

Tam sim no thiab voltage: Tam sim no yog muab los ntawm ib qho hluav taws xob sab nraud los txo thiab tso cov hlau ions ntawm lub cathode (substrate).

Substrate: Raws li cov khoom pib ntawm cathode, nws tuaj yeem yog hlau lossis lwm yam khoom siv hluav taws xob.

Anode: Feem ntau yog soluble nickel phaj uas muab cov hlau ions xav tau hauv cov txheej txheem electroplating.

Kub: cuam tshuam cov conductivity thiab deposition tus nqi ntawm cov electrolyte.

Cov ntsiab lus

Electroforming thiab electroplating yog ob qho tib si hlau tso cov txheej txheem uas siv lub hauv paus ntsiab lus ntawm electrolysis, tab sis lawv muaj ntau yam kev siv hauv kev kos npe nickel. Electroforming feem ntau yog siv los tsim cov duab kos npe, thaum electroplating feem ntau yog siv los npog lub substrate nrog txheej hlau los txhim kho nws cov khoom. Ob leeg yuav tsum tau tswj cov txheej txheem meej, suav nrog cov qauv electrolyte, tswj tam sim no thiab voltage, tswj qhov kub thiab txias, thiab lwm yam., kom ntseeg tau cov khoom zoo nickel daim ntawv lo.
