Thaum lub sijhawm oxidation thiab xim txheej ntawm cov tuag-cam khwb cia txhuas, qee zaum yuav muaj teeb meem xws li xim hla los yog xim plooj ntawm qhov tuag-casting qhov chaw. Hauv qab no yog kev tshuaj xyuas ntawm qhov teeb meem no, vim li cas ntawm cov xwm txheej no thiab cov txheej txheem kev kho mob.
Cov laj thawj thiab kev kho rau kev zas xim, tawg thiab xim hla ntawm kev tuag-cam khwb cia txhuas oxidation xim:
1. pH tus nqi ntawm cov xim dyeing yog qhov tsawg, thiab nws tuaj yeem hloov mus rau tus qauv tus nqi nrog dilute ammonia.
2. Kev tu tsis huv. Muaj zog ntxuav.
3. Cov kev ua tsis tiav ntawm cov xim zas, ntxiv dag zog rau kev txhim kho kom ua rau kev ua tiav.
4. Qhov ntsuas kub ntawm cov tshuaj ntxuav tau zoo heev, qis dua qhov kub.
5. Cov yeeb yaj kiab oxide muaj pores me me, vim tias qhov kub oxidation kub tsawg dhau los tiv thaiv zaj duab xis los ntawm kev xau ntawm sulfuric acid. Kev ntsuas kub ceev oxidation tuaj yeem tsim kho kom haum rau qhov teeb meem no.
6. Dyeing dhau nrawm, thiab qhov zas xim thib ob lub sijhawm luv heev. Dilute cov xim zas xim tuaj yeem hloov kho, txo qhov ntsuas kub zas, thiab tsim nyog ncua lub sijhawm dyeing.
7. Lub ntsuas cua kub tsis dhau, yog li nws muaj peev xwm daws tau los ntawm cua kub.
8. PH tus nqi ntawm cov kua roj sealing yog tsawg heev. Siv tshuaj tiv thaiv ammonia kom nws nce rau tus qauv.
9. Cov txhuam rau saum npoo yog yooj yim los so tawm. Qhov laj thawj loj yog vim li cas zaj duab xis ntxhib, uas feem ntau ua rau los ntawm kev kub dhau oxidation. Kev saib xyuas yuav tsum tswj hwm kom tswj hwm qhov ntsuas kub oxidation hauv qhov tshwj xeeb.
Txhawm rau kom tsis txhob cuam tshuam rau kev ua haujlwm thiab cov khoom ua tau zoo, kev ua haujlwm xim yuav tsum ua kom zoo thiab ua tib zoo, thiab kev ua haujlwm yog tseeb raws li ua tau kom ntseeg tau tias ntau lawm
