Dab tsi yog lub tank pickling?

Pickling tank yog ib qho txheej txheem rau saum npoo ntawm cov khoom siv hlau. Nws yog tsuas yog siv los tshem tawm cov oxide txheej, xeb thiab lwm yam impurities ntawm cov hlau nto, thiab npaj rau txheej txheej tom ntej.
Lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lub tank pickling yog siv cov kua qaub rau chemically corrode cov hlau nto, yog li tshem tawm cov av thiab oxidation txheej. Cov kev daws teeb meem feem ntau suav nrog sulfuric acid, hydrochloric acid, phosphoric acid, thiab lwm yam.
Cov txheej txheem pickling tank feem ntau suav nrog cov kauj ruam hauv qab no:
1. Degreasing - Siv cov tshuaj alkaline lossis emulsifier kom tshem tawm cov roj ntawm cov hlau
2. Pickling - Cov khoom hlau yog immersed nyob rau hauv lub pickling tov tshuaj corrosion thiab dissolution.
3. Kev ntxuav dej - Yaug cov kua dej uas seem nyob rau saum npoo nrog dej huv.
4 Purification - Cov hlau saum npoo yog kho nrog cov kua qaub tsis muaj zog lossis alkaline kom tiv thaiv reoxidation
5. Drying - Siv cov cua kub kom qhuav los yog lwm txoj hauv kev kom qhuav qhov saum npoo ntawm cov hlau.
Cov khoom siv ntawm pickling tank feem ntau yog tsim los ntawm pickling tank, ntxuav tank, passivation tank, thiab lwm yam, uas yuav tsum tau nruab nrog coj mus rau pickling kua ncig thiab khoom kho mob. Tsim nyog tswj lub sij hawm pickling thiab kub yog qhov tseem ceeb los xyuas kom meej qhov zoo ntawm pickling. Qhov saum npoo zoo ntawm cov khoom siv hlau tuaj yeem txhim kho tau zoo los ntawm kev siv tshuab pickling tank tsim nyog.
