Thaum cov hluav taws xob cua sov raj yog raus rau hauv cov tshuaj electroplating, nws yooj yim rau kev hloov pauv nrog cov hlau ions nrog lub peev xwm zoo.

Thaum cov hluav taws xob cua sov raj yog raus rau hauv cov tshuaj electroplating, nws yooj yim rau kev hloov pauv nrog cov hlau ions nrog lub peev xwm zoo.

1. Aluminium thiab nws cov alloys muaj kev sib raug zoo rau cov pa oxygen thiab nquag tsim cov oxide films. Thaum no oxide zaj duab xis raug tshem tawm, txheej txheej tshiab ntawm oxide zaj duab xis yog tsim nyob rau hauv lub sij hawm luv luv ntawm lub sij hawm, cuam tshuam rau lub adhesion ntawm txheej.

2. Lub peev xwm electrode ntawm txhuas yog qhov tsis zoo heev, thiab thaum muab tso rau hauv cov tshuaj electroplating, nws yooj yim los hloov cov hlau ions nrog lub peev xwm zoo, cuam tshuam rau cov adhesion ntawm txheej.

3. Txhuas thiab nws cov alloys muaj cov coefficients loj dua li lwm cov hlau, yog li electroplating yuav tsum tsis txhob ua nyob rau hauv ib qho kev hloov ntawm qhov kub thiab txias. Qhov sib txawv ntawm kev nthuav dav coefficient ntawm aluminium thiab aluminium alloys thiab lwm yam hlau txheej yuav ua rau muaj kev ntxhov siab loj, uas ua rau tsis muaj zog adhesion ntawm txheej thiab txhuas thiab txhuas alloys.

4. Aluminium yog ib qho amphoteric hlau uas yog soluble nyob rau hauv acids thiab alkalis, thiab tsis ruaj tsis khov nyob rau hauv ob qho tib si acidic thiab alkaline electroplating daws.

5. Aluminium alloy tuag-casting qhov chaw muaj cov xuab zeb qhov thiab qhov pores, uas tuaj yeem tawm cov kua nplaum seem thiab cov roj hydrogen, ua rau lawv yooj yim rau blistering thiab txo lub zog sib txuas ntawm cov txheej thiab cov hlau hauv paus.

Xaiv cov txheej txheem purification sib txawv raws li cov yam ntxwv ntawm cov kev daws teeb meem sib txawv ntawm chromium yog kev lag luam thiab siv tau zoo. Hom diaphragm electrolytic cell no zoo dua rau chrome plating tov. Copper polishing tov los yog chromium tov nrog ib tug loj npaum li cas ntawm tooj liab plated qhov chaw yuav kho nrog De copperTM chromium tov raws li ib tug tooj liab tshem tawm. Lub tank roughening tuaj yeem tsim tau zoo dua nrog lub tshuab hluav taws xob uas raug rho tawm haujlwm.
