Cov ntsiab lus tseem ceeb: zinc alloys yog dav siv hauv chav dej, hnab, khau thiab accessories, vim nws yooj yim, plasticity, tsis tshua muaj nqi thiab kev ua haujlwm siab.

Zinc alloy yog siv dav hauv cov khoom siv tu cev, hnab, khau thiab khaub ncaws accessories vim nws txoj kev yooj yim, muaj zog plasticity, tsawg tus nqi thiab kev ua haujlwm siab.Txawm li cas los xij, qhov teeb meem blistering ntawm zinc alloy (electroplating; txau) yeej ib txwm teeb meem rau cov phooj ywg ntawm hardware factories thiab electroplating factories.

Cov kev paub ntawm zinc alloy foaming nyob rau hauv electroplating factories ntawm ob peb hardware factories yog sau tseg raws li nram no:

1. Thaum pib ntawm kev tsim cov khoom siv zinc alloy, peb yuav tsum xav txog qhov chaw ntawm qhov chaw noj mov, slag tawm chaw nres nkoj thiab qhov chaw nres nkoj ntawm cov pwm.Vim tias txoj kev khiav ntawm lub workpiece nrog kev pub mis thiab slag tawm yog du, tsis muaj cua nkag, tsis muaj dej stains, tsis muaj npuas tsaus, uas cuam tshuam ncaj qha txawm tias tom qab electroplating yog bubbling.Lub workpiece nrog tsim nyog noj thiab slag tawm tuag casting muaj du nto, dawb lub teeb, thiab tsis muaj dej stains.

2. Hauv kev tsim pwm, peb kuj yuav tsum xav txog lub tonnage thiab siab ntawm lub pwm mounting tshuab.Peb tau ntsib 20-30% blistering tshwm sim tom qab zinc alloy electroplating.Ib lub Hoobkas kho vajtse phooj ywg thawj qhov kev kuaj sim, thiab 8 daim pwm, thiab yuav ua li cas daws qhov teeb meem ntawm 20-30% ua ntej foaming, thiab thaum kawg thaiv cov pwm 4 daim, thiab hloov mus rau 4 daim pwm.

3. Cov tshuaj calendering, polishing muab tshuaj txhuam thiab oxide txheej ntawm lub pretreatment nto tsis huv, thiab nto ntawm lub workpiece tom qab calendering thiab polishing yog ci.Ntau tus neeg ua haujlwm nyob rau hauv cov txheej txheem pickling ntawm cov nroj tsuag electroplating pickling casually, ua rau lub nto txuas nrog calendering tus neeg saib xyuas tsis huv, thiab ntev npuas tshwm.Tsis tas li ntawd, muaj kev sib raug zoo ntawm cov calendering agents xaiv los ntawm calendering thiab polishing nroj tsuag, thiab cov surfactants nyob rau hauv ib co calendering agents yog heev nyuaj rau ntxuav tawm.

4. Ua ntej cov khoom nkag mus rau hauv alkaline tooj liab plating da dej, tseem muaj oxide zaj duab xis (pickling zaj duab xis) nyob rau saum npoo ntawm lub workpiece.Cov wax thiab roj tshem tawm zaj duab xis tsis kho kiag li.Yog li ntawd, nws tseem ceeb heev kom tshem tawm cov yeeb yaj kiab.Nyob rau hauv thaum ntxov xyoo, nws kuj yuav raug tshem tawm nrog anti staining ntsev.Tam sim no, nws tsis raug tso cai tawm cov dej pov tseg uas muaj cov tshuaj tiv thaiv staining ntsev.Nws raug nquahu kom siv lj-d009 zaj duab xis tshem tawm hmoov, uas muaj cov txiaj ntsig zoo dua li cov ntsev ntsev, tuaj yeem tshem tawm cov nickel txheej, thiab COD emission ua tau raws li lub teb chaws tus qauv thoob ntiaj teb.

5. Muaj ntau yam organic teeb meem thiab impurities nyob rau hauv alkaline tooj liab plating da dej, thiab cov dawb cyanide tsis nyob rau hauv ntau yam.Ntsuam xyuas qhov muaj pes tsawg leeg ntawm alkaline tooj liab tank kom pom tias sodium cyanide tsawg lossis sodium hydroxide siab!Yog tias koj ntxiv cov brightener ua tib zoo, lub brightener yog siab, thiab kev tu lub alkaline tooj liab tank yog ib qho tseem ceeb heev.Nws tau pom zoo tias kev kho cov pa roj carbon dioxide yuav tsum tau ua ib zaug txhua 3-5 hnub

6. Cov conductivity ntawm alkali tooj liab lub tog raj kheej kuj tseem ceeb heev.Seb lub anode dissolves ib txwm thiab seb lub anode tooj liab phaj txaus yuav ua rau blistering

7. Zinc alloy khoom blister thaum lawv tawm ntawm qhov cub;nws yuav tshwm sim los ntawm qhov kub tsis sib xws, uas yog, kub dhau heev lawm.Vim tias qhov tuag casting tsis nruj, nws yooj yim rau muab cov kua qaub rau hauv cov dej stains thiab trachomas ntawm zinc alloy.Txawm hais tias muaj cov txheej txheej saum npoo av, cov kua qaub thiab zinc tseem yuav muaj cov tshuaj tiv thaiv, ua kom muaj ntau ntawm hydrogen h.Thaum huab cua siab nyob rau hauv siab dua atmospheric siab mus rau ib qho twg, thiab kub siab yuav ua npuas.
