Dab tsi yog qhov tseem ceeb ntawm cov txheej txheem pickling?

Cov txheej txheem pickling tau siv dav hauv kev kho cov hlau saum npoo hlau. Nws cov txiaj ntsig tseem ceeb yog cov khoom siv tu nyob rau hauv cov nyhuv tu nyob rau hauv cov nyhuv tu nyob rau hauv cov nyhuv tu nyob rau hauv cov nyhuv tu nyob rau hauv cov nyhuv tu nyob rau hauv cov nyhuv tu nyob rau hauv cov nyhuv tu, cov txiaj ntsig kev ua tau zoo thiab kev ua lag luam ua tiav, raws li hauv qab no:
1. Kev tshem tawm ntawm cov nplaim hluav taws xob thiab tu kom huv
Muaj hwj chim tshaj tawm ntawm oxide nplai thiab xeb
Acid (xws li hydrochloric acid, nitric acid, nitric acid, etcide:, Rowces) thiab tooj, thiab tooj, ua rau cov hlau mus rau lub hauv paus huv si.
Piv txwv li: Tom qab cov hlau workpiece yog pickled nrog cov nplai oloCoCloric tuaj yeem raug tshem tawm tag nrho 10 txog 30 feeb, uas yog ntau dua li ntau dua li cov neeg kho tshuab sib tsoo.
Uniform huv, tsis muaj ceg tuag
Acid tuaj yeem nkag mus rau hauv cov khoob, qhov lossis cov txheej txheem nyuaj ntawm kev ua haujlwm tu txhua yam (xws li sandblasting) yog qhov nyuaj kom mus txog qhov muab zais cia.
2. Txhim kho cov haujlwm saum npoo av thiab ua kom cov txheej txheem ua kom zoo dua
Txhim Kho Cov Txheej Txheej Adadhion
Tom qab pickling, lub hlau nto yog microscopically ntxhib (thiab thaj chaw tshwj xeeb ntau, uas tuaj yeem txhim kho cov pa hluav taws xob, uas tuaj yeem txhim kho cov khoom siv hluav taws xob, uas tuaj yeem txhim kho hluav taws xob, kub-dip galvanizing) thiab substrates.
Piv txwv li: Tom qab pickling, autom steel phaj yog txau nrog cov xim, thiab kev pheej hmoo ntawm cov xim pleev xim yog txo los ntawm ntau dua 50%.
Pretricative rau electroplating \/ Tshuaj Plating
Pickling tuaj yeem txav tshem tawm saum npoo av, oxides ncaj qha rau kev sib chwv hluav taws xob thiab cov hlau, thiab txhob txwm xws li blistering thiab pitting hauv txheej.
3. Cov txheej txheem hloov tau, haum rau ntau yam ntawm cov hlau thiab cov xwm txheej
Tau tshaj nrog ntau hom kua qaub
Hydrochloric acid: haum rau hlau xeb tshem tawm, kev tawm tsam sai ntawm chav tsev kub, thiab tus nqi qis.
Sulfuric acid: tuaj yeem siv rau qhov kub-pickling (xws li kub-rolled hlau), thiab muaj qhov cuam tshuam zoo ntawm kev tshem cov tuab xide nplai.
Nitric Acid + Hydrofluoric acid (sib xyaw ua ke acid (siv rau pickling ntawm stainless hlau thiab aluminium alloys, nrog ob qho teeb meem oxide tshem tawm thiab cov teebmeem.
Phosphoric acid: tsis muaj zog acid, feem ntau siv rau cov hlau phosphallating pretreatment los ua cov yeeb yaj kiab phosphaating los txhim kho corrosion.
Haum rau kev ua haujlwm sib txawv
Immersion: Haum rau cov pob ntawm qhov chaw me me lossis cov haujlwm ua haujlwm nyuaj, kev ua haujlwm yooj yim.
Txau: Siv rau hauv cov kab ntau lawm (xws li steel phaj pickling kab), muaj efficiency, acid tuaj yeem rov ua tau.
Electrolytic pickling: ntxiv dag zog los ntawm hluav taws xob tam sim no, luv luv lub sijhawm xaiv, thiab txo cov volatilization kua qaub ua pos huab.
4. Tus nqi tsawg thiab tseem ceeb nyiaj txiag
Tsawg cov khoom siv
Industrial-qib hydrochloric acid thiab sulfuric acid thiab cov sulfuric acid thiab siv tau ntawm hydrochloric acid reteneration thiab rov qab los txo cov khoom noj.
Cov khoom lag luam qis
Qhov yooj yim pickling tank muaj cov qauv yooj yim thiab tsis xav tau cov khoom siv kho txhua yam, uas haum rau cov lag luam me thiab nruab nrab; Txawm hais tias thawj zaug kev nqis peev ntawm cov kab ntau lawm yog siab, nws tuaj yeem txhim kho kev ua tau zoo hauv lub sijhawm ntev.
Txo cov khoom siv ua tiav ntxiv
Ib qho khoom siv hlau huv tuaj yeem txo cov kev hnav pwm nyob hauv cov yob tom qab, stamping thiab lwm yam txheej txheem lub neej.
5. Txhim kho kev tiv thaiv ib puag ncig thiab kev nyab xeeb txoj kev nyab xeeb (kev txhim kho cov txheej txheem niaj hnub)
Tsawg-toxic acid hloov
Maj mam tshem tawm cov kua qaub heev (xws li hydrocyanic acid), siv cov accocy acid thiab aminosulfonic acid, txo cov pa phem rau cov roj ntsha tsis huv (xws li HCl).
Mature Khibe Roj \/ Wastewater Kev Kho Mob
Acid Mist yog nqus thiab kho los ntawm cov kws txhuam hniav thiab tso tawm hauv kev ua raws li cov qauv.
Cov khib nyiab yuav tuaj yeem hloov kho los ntawm kev kho mob neutralization, nag lossis daus, kev kho mob mem tes kom rov qab siv hlau +) thiab rov ua dej cov khoom siv dej.
Kev siv tshuab txo cov kev pheej hmoo
Niaj hnub nimno pickling kab yog nruab cov kab sib luag, uas tuaj yeem saib xyuas cov accor messentract, lub sij hawm kub thiab ua haujlwm sijhawm los txo kev pheej hmoo ntawm kev sib cuag nrog cov muaj zog acids.
VI. Ntau yam ntawm cov ntawv thov
Pickling thev naus laus zis yuav luag txhua yam kev lag luam hlau:
Kev lag luam hlau: xeb tshem tawm ntawm kub-rolled steel daim hlau, pickling thiab phosphating ntawm cov kav hlau steel.
Tsheb tsim khoom: Pretreatment ntawm lub cev panels, ntxuav ntawm cov chaw ua ntej elecloplating.
Aerospace: tshem tawm ntawm oxide zaj duab xis los ntawm txhuas alloy qhov chaw los xyuas kom meej precision vuam zoo.
Kev lag luam hluav taws xob: Kev tu ua ntej etching princuit coircuit Cours (PCBs) kom ntseeg tau tias cov kev sib tw.
Hlau siv hluav taws xob: Tshem cov npoo av thiab xeb ua ntej rov ua dua tshiab ntawm cov hlau los txhim kho tus nqi rov qab ua dua tshiab.
Lub ntsiab
Tus txheej txheem pickling tau dhau los ua ib qho ntawm cov tseem ceeb thev naus laus zis rau kev kho mob hlau vim tias nws muaj peev xwm ntxuav tau zoo, cov txheej txheem yooj yim, cov txheej txheem yooj yim, cov txheej txheem yooj yim thiab muaj txiaj ntsig zoo. Txawm hais tias cov txheej txheem tsooses muaj qee cov kev sib tw thiab kev nyab xeeb ntawm cov khoom siv tshuab hluav taws xob yuav txuas ntxiv mus nthuav dav thiab ua kom muaj kev lag luam ntxiv hauv kev tsim khoom thiab cov khoom siv ntsuab.
