Ua li cas zinc alloy tuag-casting manufacturers daws huab cua npuas?

Sijhawm: 2020-06-03 Ntaus: 20

Zinc alloy yog cov alloy tsim cov zinc ntxiv nrog rau lwm lub ntsiab lus. Zinc alloys yog yooj yim tsim, muaj cov yas muaj zog, tus nqi qis, kev ua haujlwm siab, thiab siv ntau yam. Txawm li cas los xij, cov teeb meem foaming (electroplating thiab txau) ntawm Jiangmen zinc alloy tuag castings yog qee qhov teeb meem. Yog li yuav ua li cas los daws qhov teeb meem ntawm qhov blistering? Cov ntsiab lus nram qab no:

  

1. Cov khoom lag luam tsim

Thaum tus qauv tsim ntawm zinc alloy tuag-casting khoom pib, nws yog ib qho tsim nyog yuav tsum xav txog qhov chaw nres nkoj pub, slag paug chaw nres nkoj thiab chaw teeb tsa ntawm qhov tuag-casting pwm. Vim tias txoj kev ntws tawm ntawm lub workpiece rau kev pub mis thiab slagging yog tus du, tsis muaj cua nkag, tsis muaj dej noo, thiab tsis muaj lub npuas tsaus nti, uas cuam tshuam ncaj qha seb puas muaj qhov txhab hluav taws xob tom ntej. Tsim nyog pub mis thiab slagging. Cov pwm tuag. , Tsis muaj dej noo nyob.

  

 2. Kev txhim kho ntawm tuag casting pwm

Hauv kev txhim kho tuag-ua pwm pwm, cov tonnage, lub siab, lub siab tsis txaus, thiab kev tso pa tsis zoo ntawm lub tshuab moulding yuav tsum tau txiav txim siab. Tsis muaj teeb meem li cas qhov kev npaj ua ntej ntawm kev kho lub plating yog daws, muaj ib txwm 20-30% lub hlwv. Cov pwm tab tom thaiv thiab hloov mus rau ob peb Daim, tsis muaj rov cuam tshuam tom qab plating.

 

3. Ua ntej-kho saum npoo

Cov txheej txheem ua ntej kho ntawm cov kua polishing, polishing muab tshuaj, thiab oxide txheej tsis ntxuav, thiab muaj feem ntau dov. Cov zinc alloy tuag-casting tom qab dov yog ci. Coob tus neeg ua haujlwm hauv cov txheej txheem ntawm kev cog ntoo cog ntoo yog pickled casually. Tus neeg saib xyuas polishing uas txuas nrog rau saum npoo yog tsis ntxuav, thiab blistering feem ntau tshwm sim. Ib qho ntxiv, lub calender siv los ntawm calendering thiab polishing tsob nroj kuj tseem muaj kev sib raug zoo, thiab qee qhov surfactants hauv lub calender yog qhov nyuaj rau ntxuav.

 

4. Thaum cov khoom nkag rau hauv alkali tooj liab

Ua ntej cov khoom lag luam nkag mus rau alkali tooj liab plating tank, lub zinc alloy tuag-casting qhov chaw tseem muaj cov yeeb yaj kiab dub uas tsis kho nrog oxide zaj duab xis kom tshem tau cov quav ciab thiab roj. Yog li, kev tshem tawm ntawm daim nyias nyias yog qhov tseem ceeb heev. Hauv lub xyoo thaum ntxov, nws tuaj yeem raug tshem tawm los ntawm kev siv cov ntsev los tiv thaiv. Kev tiv thaiv ib puag ncig tam sim no tsis pub tso tawm cov dej khib nyiab uas muaj cov ntsev tawm tsam.

  

5. Alkali tooj liab plating tank

Muaj ntau cov organic ntau hauv alkaline tooj liab plating tank, thiab muaj ntau yam tsis haum, thiab cov dawb cyanide tsis yog nyob rau hauv qhov ntau. Ntsuam xyuas cov khoom xyaw ntawm cov xim lim dej alkaline kom pom tau tias sodium sodium cyanide qis los yog cov sodium hydroxide ntau dua! Tseem ceeb heev, nws raug nquahu kom kho cov pa roj carbon monoxide ib zaug txhua 3-5 hnub.

  

6. Kev coj ua ntawm alkali tooj liab lub tog raj kheej

Lub conductivity ntawm alkaline tooj liab kheej kuj tseem ceeb heev. Seb lub anode yog yaj kom zoo thiab lub anode tooj liab txaus yog qhov yuav ua rau blistering.

  

7. The product foams after coming out of the oven

Nws yuav yog los ntawm qhov kub tsis sib xws ntawm qhov cub, uas yog, qhov kub thiab txias dhau lawm. Vim tias tsis muaj qhov nruj thaum lub sij hawm tuag casting, nws yog qhov yooj yim rau cov kua qaub nkag mus rau hauv cov dej ua paug ntawm zinc alloy tuag castings.Qhov cov kua qaub thiab zinc yuav tseem muaj tshuaj lom neeg txawm tias muaj txheej txheej saum npoo, ua kom muaj dej ntau ntawm hydrogen H .Thaum lub siab sab hauv siab siab dua li qhov ntsuas cua Nyob rau qee yam, ntxiv qhov kub siab yuav tsim ua npuas.
