Qhov tseem ceeb cuam tshuam rau qhov zoo ntawm qhov chawtooj liab rodsyog cov txheej txheem ntau lawm, thiab yog ze ze rau tag nrho cov txheej txheem ntau lawm.Yog vim li cas rau oxidation ntawm liab tooj liab pas nrig yog raws li nram no:
1. Lub sij hawm ua ntej ziab ntawm qhov ntxig yog ntev heev.
2. Cov kua qaub corrodes daim ntawv tooj liab thaum cov tshuaj tua kab yog damp.
3. Cov tooj liab yog cov tshuaj molecule uas tsis yog tshwj xeeb, thiab nws yog ib qho yooj yim kom plam cov khoom siv hluav taws xob thiab ua rau oxidation.
4. Tsis tas li ntawd, qhov txheeb ze av noo ntawm cov pa roj thiab huab cua, huab cua muaj kuab paug nyob rau saum npoo ntawm cov hlau hlau kos tooj liab phaj ntawm cov yas-coated tooj liab raj, kev daws teeb meem rau oxidation ntau lawm thiab kev kho ntawm cov pas nrig tooj liab, corrosion kuj ntawm lub raj tooj liab, sediment gas, thiab lwm yam yuav ua rau oxidation ntawm tin ore..
5. Cov ntawv ci liab tooj liab tsis tau muab ntxuav kom huv thiab huv si ua ntej electroplating, thiab cov cim dub tshwm rau ntawm qhov chaw, uas yog lub khob ntsev uas tshwm sim los ntawm kev poob ntawm cov khoom siv hluav taws xob vim yog oxidation.
6. Tam sim ntawd tom qab tshem tawm, kev ziab kom qhuav los yog cov txheej txheem tsis zoo, cov dej seem, cov tshuaj ntxuav tes, thiab lwm yam, thiab tooj liab hydroxide thiab co2 nyob rau hauv cov huab cua ua rau cov tshuaj electrochemical, uas ua rau dub-grey cuprous, thiab ntsuab nyob rau hauv hnyav ntsev.
Txoj kev:
1. Cov hlau hlau kos duab tooj liab phaj ntawm cov yas-coated tooj liab raj txhim kho kev saib xyuas ntawm cov roj inert thaum lub sij hawm tag nrho cov txheej txheem ntawm txoj kev kho cua sov.Vim yog cov tshuaj zoo tshaj plaws ntawm tooj liab, nws tuaj yeem ua rau cov tshuaj tiv thaiv sai nrog cov pa roj carbon monoxide ntau dua hauv huab cua thaum lub sij hawm kub kub kho.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua kom muaj zog ntau dua cov roj inert hauv nws kom tiv thaiv cov tooj liab los ntawm oxidized.
2. Txhim kho qhov kev tshem tawm ntawm qhov chaw ntawm tus pas nrig tooj liab thiab tuav lub siab gloss.Nyob rau hauv cov txheej txheem ntawm kev ntxhib dov thiab kev kho cua sov, qhov saum npoo ntawm cov pas nrig tooj liab yuav ua rau oxides, thiab kev tshem tawm xws li kev kho phosphating, acid tshem tawm, thiab stainless hlau passivation yog nqa tawm.
3. Cov yas-coated tooj liab raj thiab cov hlau hlau-kos duab tooj liab phaj txhim kho kev tswj cov txheej txheem ntau lawm thiab cov txheej txheem ntau lawm.Siv cov txhuam muag muag thiab dej txias kom tshem tawm cov khib nyiab ntawm tus pas nrig tooj liab.Ua ntej kub dov, tus pas nrig tooj liab yuav tsum tau qhwv nrog ib daim ntawv hauv ob sab phlu.Tsis tas li ntawd, siv tag nrho cov roj kub dov txoj kev, txhim kho thiab kho cov khoom siv degreasing ntawm cov extruder txuas ntxiv, ua kom cov kub dov nrawm nrawm, thiab siv txhua txoj hauv kev kom tshem tawm cov pa phem hauv qhov chaw ntawm cov tooj liab liab.Tsis tas li ntawd, txhua tus neeg tsim khoom thiab kev tswj xyuas cov neeg ua haujlwm txhim kho lub tuam txhab kev tswj hwm kev tsim khoom thiab txhim kho kev tshuaj xyuas.
4. Txhim kho tom qab ntim khoom uas tswj cov khoom tsim tawm.Cov pas nrig tooj liab yuav tsum tau qhuav kom ntau li ntau tau tom qab kev kho phosphating.Qhov chaw ntub dej ntawm thaj chaw yuav ua rau kom muaj kev xeb ntawm tooj liab thiab cuam tshuam rau qhov tseeb ntawm cov khoom tsim tawm.Yog li ntawd, txhawm rau kom ntseeg tau tias cov khoom ziab kom zoo dua, kev ceev faj ob zaug raug coj los siv.Ntxiv rau kev ziab cov khoom kom ntau li ntau tau, nyob rau hauv cov xwm txheej ntawm kev ntim khoom, thawj zaug siv lub hnab ntim khoom los khi, thiab tom qab ntawd qhwv nws nrog zaj duab xis daj, thiab lwm yam. Nws tuaj yeem tiv thaiv tau qhov hnyav ntawm cov dej noo hauv lub cev thaum lub sijhawm thauj mus los.
