1. Dab tsi yog residual emulsion? Dab tsi tshwj xeeb cuam tshuam nws ua rau qhov zoo ntawm cov khoom siv galvanized?
Emulsion yog cov kua siv rau lubrication thiab txias thaum txias dov. Tom qab dov, qee qhov tseem nyob ntawm qhov chaw ntawm cov sawb hlau. Tom qab cov dej noo evaporates, nws tsim cov zaj duab xis roj uas muaj cov roj dov thiab cov khib nyiab hlau.
Cov residues ua rau muaj kev phom sij txaus ntshai rau cov txheej txheem galvanizing tom ntej, feem ntau ua rau peb qhov teeb meem loj:
** Ua rau txheej txheej tev thiab txheej tsis tiav: ** Yog tias cov emulsion thiab hlau hmoov ntawm lub sawb hlau tsis huv huv ua ntej nkag mus rau hauv zinc da dej, qee qhov chaw yuav tsis ntub los ntawm cov kua zinc, nws thiaj li ua rau "dub pob" los yog ua rau tsis zoo adhesion ntawm tag nrho cov galvanized txheej, yooj yim tev tawm thaum ua tom ntej.
** Ua rau cov pob zeb xeb: ** Yog tias cov hlau coil tseem muaj cov khoom seem emulsion thaum lub sij hawm thauj los yog cia, cov electrolytes thiab noo noo nyob rau hauv nws yuav hnov mob nrog cov hlau phaj los tsim cov pob zeb uas nyuaj rau so, cuam tshuam ncaj qha rau cov tsos thiab siv.
Kev kis kab mob ntawm zinc pots thiab tsim cov khoom pov tseg: Thaum impurities xws li hlau hmoov hauv emulsion tau nkag mus rau hauv lub lauj kaub zinc, lawv hnov mob nrog zinc los tsim zinc slag uas yog insoluble hauv zinc kua. Cov khib nyiab pov tseg no tsis tsuas yog paug cov tshuaj plating thiab ua rau cov nqi ntau lawm, tab sis kuj adheres rau saum npoo ntawm cov sawb hlau, ua rau muaj qhov tsis xws luag.
Thib ob: Yuav ua li cas tiv thaiv cov seem ntawm qhov chaw los ntawm kev tswj cov emulsion system nws tus kheej?
"Kev tiv thaiv zoo dua li kho" yog thawj kauj ruam ntawm kev tswj cov khoom seem. Qhov tseem ceeb yog los xyuas kom meej tias cov emulsion siv nyob rau hauv lub dov zeb yog "huv."
Kev tuav tswj cov ntsuas physicochemical kom meej: Tsim kom muaj kev sim nruj kom siv cov txheej txheem tswj. Piv txwv li, ib qho concentration tsawg dhau yuav ua rau lubrication tsis txaus thiab muaj kev sib txhuam ntau ntxiv, uas ua rau cov hmoov hlau loj tuaj yeem ua rau cov kab nrib pleb; siab heev ib tug concentration yuav cuam tshuam cov ncej -rolling volatilization. Qhov tseem ceeb yog tswj cov hmoov hlau cov ntsiab lus hauv qab 300 ppm thiab tswj cov kev ua haujlwm tseem ceeb xws li conductivity thiab saponification tus nqi hauv lawv qhov kev ua haujlwm zoo.
Tiv thaiv kom tsis txhob muaj cov roj paug nkag mus rau hauv lub cev: Cov roj hydraulic thiab cov roj bearing tuaj yeem nkag mus rau hauv emulsion yuav tsum tau muab tshem tawm sai li sai tau siv cov khoom siv skimming, thiab cov roj xau yuav tsum raug txo los ntawm kev saib xyuas. Thaum muaj kab mob, cov roj paug no yuav ua rau lub zog ruaj khov thiab tsis muaj zog ntawm cov emulsion, uas ua rau graphite-zoo li cov pa roj carbon dub seem tom qab annealing.
3. Yuav ua li cas kom tshem tawm cov emulsion adhering rau lub strip siv lub cev txoj kev?
Kev tshem tawm lub cev ntawm lub zeb tawm yog ib txoj hauv kev ncaj qha thiab siv tau zoo ntawm kev txo cov khoom seem, feem ntau ua tiav los ntawm qhov siab - cua purging system.
Optimizing lub purging system: Lub hauv paus yog los txhim kho cov huab cua purging muaj peev xwm ntawm lub zeb tawm, nrog rau nce tus naj npawb ntawm purging nozzles, nce compressed cua siab, scientifically teem lub purging lub kaum sab xis los tsim ib tug ua tiav huab cua thaiv barrier, thiab ntxiv ntug suction kiv cua kom tshem tawm tshaj emulsion ntawm cov npoo. Los ntawm kev sib xyaw ua ke ntawm "tshuab" thiab "suction," cov kua emulsion adhering rau steel strip nto tuaj yeem raug tshem tawm mus rau qhov loj tshaj plaws.
Siv cov ntawv tshaj tawm- dov kub kub: Cov kub kub uas tsim tawm thaum dov ua rau cov emulsion residual evaporate sai. Cov kev tshawb fawb tau pom tias cov ncej siab dua - dov kub yog qhov tsim nyog rau txo cov roj seem. Yog li ntawd, nyob rau hauv ntau lawm, lub dov ceev thiab txias dej ntim yog precisely kho kom paub meej tias cov ncej -rolling strip kub yog txaus los txhawb emulsion evaporation.
4. Yuav ua li cas cov txheej txheem coiling thiab annealing cuam tshuam cov residues, thiab cov txheej txheem yuav tsum tau kho li cas?
Yog tias cov khoom seem tseem nyob rau ntawm daim kab xev nplaum thaum coiling, cov tshuaj no yuav raug kaw hauv lub kauj thiab ua rau muaj kev hloov pauv physicochemical thaum lub sij hawm tom qab siab -kub annealing.
Kev ua kom zoo tshaj plaws ntawm cov txheej txheem coiling: Cov kab nrib pleb tsis zoo (xws li lub xub ntiag ntawm corrugations) tuaj yeem ua rau muaj kev sib khi nruj heev ntawm cov txheej coil, cuam tshuam emulsion evaporation. Nyob rau hauv cov ntaub ntawv no, lub coiling nro tuaj yeem raug txo kom tsim nyog los ua kom qhov sib txawv interlayer, muab cov channel rau cov volatiles kom dim.
Kev kho kom zoo ntawm cov txheej txheem annealing: Thaum lub sij hawm tseem ceeb ntawm cov cua sov lub qhov cub kom txog li 300℃mus rau 500 degree, siab -flow-rate hydrogen thiab nitrogen gas yuav tsum tau siv rau lub zog purging kom sai sai tshem tawm cov evaporating emulsion thiab roj vapors los ntawm lub cub tawg, tiv thaiv lawv los ntawm kev kub siab. residues ntawm daim tawv nqaij.
5. Thaum cov khoom seem tsis tuaj yeem zam tau, qhov kev tu thiab kho qhov tseem ceeb yog dab tsi rau kev tshuaj xyuas tom ntej?
Rau txhua txoj kev tsim khoom lag luam, qhov kawg "theem tu" yog qhov tseem ceeb; nws yog kab kawg ntawm kev tiv thaiv kom ntseeg tau cov khoom zoo.
Tsim kom muaj txheej txheem tu kom huv: Ib qho kev tu vaj tse tshwj xeeb tau teeb tsa rau ntawm cov kab kub -dip galvanizing ntau lawm. Los ntawm peb lub tswv yim ntawm cov tshuaj tua kab mob ntawm cov roj stains los ntawm cov tshuaj alkaline, electrochemical tshem tawm cov hmoov hlau zoo heev los ntawm cov hluav taws xob, thiab kev txhuam lub cev los ntawm cov txhuam txhuam, cov sawb hlau tau ua kom ntseeg tau kom ncav cuag "daim iav- zoo li" huv lub xeev ua ntej nkag mus rau hauv zinc da dej.
Txhim kho qhov kev tshuaj ntsuam xyuas zoo: Cov ntawv ua tiav galvanized yuav tsum tau ua tib zoo tshuaj xyuas qhov zoo los xyuas qhov ua tau zoo ntawm kev tswj xyuas. Txhua qhov tsis txaus ntseeg dezincification, tsis tiav galvanizing, lossis cov pob zeb raug txiav txim siab raws li cov khoom tsis raug, yog li tsav kev txhim kho ntxiv ntawm kev tswj hwm emulsion hauv cov txheej txheem dov ua ntej.
