1.Dab tsi yog lub hauv paus ntsiab lus qab acid pickling?
Pickling ua haujlwm los ntawm kev siv tshuaj tiv thaiv kom tshem tawm cov hlau oxide nplai (xeb) los ntawm qhov kub ntawm -rolled strip steel. Raws li ib txwm muaj, cov tshuaj tiv thaiv no tseem ceeb nres tom qab cov hlau oxide raug tshem tawm, ua tsaug rau kev tiv thaiv corrosion inhibitors thiab kev tswj cov txheej txheem. Txawm li cas los xij, yog tias lub sijhawm pickling ntev dhau lawm, cov kua qaub ntau dhau, lossis qhov kub thiab txias siab dhau, cov tshuaj tiv thaiv yuav ua rau cov hlau matrix nws tus kheej, ua rau cov hlau tawg thiab poob.
2.Dab tsi yog cov cim tshwj xeeb ntawm kev tshaj -pickling?
Ua kom tiav thinning: Qhov saum npoo ntawm cov hlau phaj yog corroded ntau dhau, tshwm greyish -dub, ntxhib, thiab npub. Hauv qhov xwm txheej hnyav, nws tuaj yeem tsim pitting lossis qhov me me (pitting corrosion). Qhov kev xeb no sib npaug "noj" txheej ntawm cov hlau, ua rau lub thickness ntawm tag nrho cov hlau kauj yuav qis dua tus qauv yuav tsum tau ua.
3.Yuav ntau npaum li cas pickling ua rau hauv zos thinning?
Rau qee cov qib steel tshwj xeeb, xws li duplex stainless hlau, cov txheej txheem pickling tsis zoo tuaj yeem ua rau cov khoom hnyav dua. Cov ntaub ntawv patent tau hais meej meej tias thaum tsim cov khoom nyias nyias - ntsuas duplex stainless hlau, cov txheej txheem tswj tsis zoo tuaj yeem "yooj yim ua rau muaj teeb meem ntawm qhov dav txo thiab thickness thinning," thaum kawg ua rau cov khoom seem siab thiab qis tawm los.
4.Dab tsi yog qhov kev txiav txim ntawm qhov loj ntawm thickness txo?
Qhov tuab ntawm cov nplai oxide nyob rau saum npoo ntawm ib txwm kub- dov strip steel feem ntau yog nyob nruab nrab ntawm 7 thiab 20 micrometers. Txoj kev pickling yuav tsum tsuas yog tshem tawm cov thickness ntawm oxide txheej. Tshaj -pickling, txawm li cas los xij, dissolves ib txheej ntxiv ntawm cov hlau matrix, uas tuaj yeem nyob ntawm ob peb micrometers mus rau kaum micrometers. Rau precision txias- cov khoom dov, qhov no yog qhov txaus los ua kom lub thickness ntau dhau thiab ua rau cov khoom seem.
5.Dab tsi yog qhov tseem ceeb ntawm cov kua qaub pickling?
Lub hauv paus ntawm pickling yog nyob rau hauv "precision" thiab "moderation." Thaum nws tawm ntawm kev tswj hwm thiab dhau los ua "tshaj-pickling," nws tsis yog ib qho yooj yim ntawm kev ntxuav, tab sis cov txheej txheem hlau tsis muaj kev tswj xyuas, ua rau muaj kev cuam tshuam ntawm cov hlau phaj thiab qhov chaw puas. Yog li ntawd, hauv kev tsim khoom, cov txheej txheem pickling yuav tsum tau tswj los ntawm cov txheej txheem nruj kom tsis txhob muaj qhov xwm txheej no.
