Cov qauv thiab kev ua haujlwm ntawm 18K kub tooj liab antimony alloy rau hluav taws xob cua sov raj

Cov qauv thiab kev ua haujlwm ntawm 18K kub tooj liab antimony alloy rau hluav taws xob cua sov raj

(1) Cov qauv thiab kev ua haujlwm ntawm Rose liab 18K kub tooj liab antimony alloy plating:

Potassium kub cyanide 6-12g/L

Potassium antimony tartrate 4.5g / L

Potassium dihydrogen phosphate 60g / L

Tooj liab (ntxiv nrog tooj liab sib koom ntsev) 5g / L

EDTA -2Na20g/L

Qhov kub thiab txias 45-50 degree

PH tus nqi 4.5-60

Tam sim no qhov ceev 1.0-1.5/dm2

Kev txav los yog kev sib hloov ntawm lub stirring cathode

Anode phaj khoom: stainless hlau phaj

3, Dai hauv luxurious daj 18K kub

Siv cov txheej txheem kub plating ntawm tooj liab ua piv txwv: cov cuab yeej dai → degreasing → dej ntxuav → kua qaub ntxuav → dej ntxuav → ci npib tsib xee plating → dej ntxuav → 18 K kub plating → thib ob rov siv dua → dej ntxuav → dej kub ntxuav → ziab → kev tshuaj xyuas → ntim.

(1) Cov qauv thiab kev ua haujlwm ntawm 18K kub plating tov nrog xim daj:

Potassium kub cyanide 7-10g/L

Potassium cyanide 50-60g/L

Potassium silver cyanide 2.0-2.5g/L

Ammonium hydroxide 50-60g/L

Potassium carbonate 10g / L

PH tus nqi 11.0~12.5

Qhov kub thiab txias 18-23 degree

Cathode tam sim no ceev 0 3-0.6A/dm

Do lub cathode (25 zaug / min) los yog tig nws

Anode khoom stainless hlau phaj

(2) Cov ntsiab lus tseem ceeb los tuav:

① Qhov piv ntawm supplementing kub potassium cyanide thiab nyiaj poov tshuaj cyanide yog 100:20-25, uas txhais tau hais tias ntxiv 10g ntawm kub potassium cyanide ib liter thaum ntxiv 2.0-2.5g ntawm cov nyiaj potassium cyanide;

② Potassium cyanide yuav tsum tau khaws cia ntawm qhov siab ntawm 45-60g/L, vim tias qib qis yuav cuam tshuam rau kev coj ua thiab kev sib koom tes. Ammonium hydroxide yuav tsum tsis tu ncua thiab me ntsis ntxiv (tab sis tsis dhau), vim nws tuaj yeem kho tus nqi pH thiab ua kom lub teeb ci ntawm txheej txheej;

③ Thaum cov ntsiab lus kub hauv cov tshuaj tsis tshua muaj, cov txheej txheej zoo li spongy thiab npub, thiab cov khoom yuav tsum tau ntxiv sai;

④ nruj me ntsis tswj qhov kub ntawm {{0}} degree ; Qhov zoo tshaj plaws cathode tam sim no ceev yog 0.3-0.8A/dm.
