Nyob rau hauv cov txheej txheem ntawm cov phaj txiav txim siab, qhov kev sib daj sib daj sib deev, kev thaij duab, lub computer tso tawm zaj duab xis, los yog xim kasfes, qhov tseem ceeb yog tshwm sim los ntawm dej-insoluble sulfide-sulfur hauv zaj duab xis emulsion, hauv kev ua hauj lwm. Muaj ntau ntau yam uas ua rau lub daj daj ntawm cov duab yeeb yam.
1. Thaum npaj tus tsim tawm, nws tsis npaj siab ncaj qha raws li qhov kev faib ua feem ntawm tus qauv. Lub cev muaj zog ntawm cov kua tshuaj yog qhov muaj zog heev, cov tshuaj tsim tau yooj yim oxidized thiab cov tawv nqaij, cov tshuaj tsim los siv ntev, cov kev tsim kho yog txo qis qis dua, qhov kev tsim kho yog oxidized rau reddish xim av, yooj yim tsis muaj zog los yog txawm ploj, yog li ntawd Cov yeeb yaj duab tshaaj tawm ntawm tus tsim tawm saum toj no tej zaum yuav dyed daj los yog xim av vim lub suab ntawm qhov saum npoo zaj duab xis.
Raws li ib txwm muaj, daim duab, luam, thiab hluav taws xob cais tag nrho siv cov ntawv xov xwm tawv. Qhov siab zoo thiab kev ruaj siab loj hlob kev tsim txhua yam siv ib lub hnab ntawm cov tshuaj, uas tuaj yeem ua tib zoo ntxuav 8m2 zaj duab xis. Tus tsim tawm yuav tsum tau siv rau lub sijhawm. Hloov cov tshuaj tshiab.
2. Cov tshuaj txhim kho yog cov tshuaj sodium thiosulfate + dej + sodium sulfite. Formulation ntawm kho daws: sodium thiosulfate: 350 g, sodium sulfite: 8 g, dej: 1000 mL.
Lub hom phiaj ntawm kev txhim kho yog yuav tsum txhim kho cov duab ntawm qhov sib txawv thiab qhov sib txawv tau tom qab kev txhim kho tiav. Kev ua haujlwm ntawm txoj kev daws teebmeem yog ua kom tsis txhob muaj cov kabmob alkaline los ntawm kev tsim cov tshuaj kua txob nrog rau txoj kev loj hlob, txhim kho cov duab, thiab muab cov nyiaj phom uas tsis muaj teebmeem. Cov ntsev sodium thiosulfate hauv cov tshuaj kho tau zoo rau cov kua qaub zog heev, los yog kub kub, thiab dawb sulfur yog precipitated. Cov dawb sulphom no tuaj yeem hnov mob nrog cov nyiaj ntawm zaj duab xis los ua nyiaj sulfide. Cov xim ntawm silver sulfide yog xim av, yog li cov xim ntawm zaj duab xis yog dyed xim av. Yog li ntawd, lub acidity ntawm kev daws teeb meem yuav tsum tsis txhob muaj zog heev, thiab qhov ntsuas ntawm qhov kho cov dej yuav tsum tsis txhob siab dhau.
3. Qhov tsis zoo ntawm txoj kev daws teeb meem tuaj yeem ua rau zaj duab xis kom daj. Vim qhov kev kho ntawm kev kho zaj duab xis, nws muaj feem xyuam rau qhov nyiaj sodium thiosulfate ntxiv nyob rau hauv txoj kev kho kho. Qhov concentration ntawm txoj kev daws teeb meem yog siab, thiab qhov kho ceev yog ceev. Yog tias qhov kev daws teeb meem zoo tshaj li ntawm 45%, txoj kev daws teeb meem yog tuab dhau lawm, thiab zaj duab xis yog tuab heev. Qhov tsis muaj kev puas tsuaj nyiaj hnyav tau qhov tsawg tshaj plaws, tiam sis txo cov txheej txheem daws teeb meem, kom nws muaj kev cuam tshuam. Yog li, thaum kho qhov tsis zoo tswj, cov nyhuv ntawm txoj kev daws teeb meem tuaj yeem tsis muaj zog, thiab qhov kho tsis tob thiab daj.
4, kev daws teeb meem yog cov qub thiab tsis tsim nyog, thiab zaj duab xis tuaj yelling tau yog tias tsis yog kiag li. Tom qab kho cov tshuaj siv tau ntev, kev kho ntawm kev kho yog degraded, thiab cov teebmeem kho tsis tau zoo, yog li ntawd tag nrho cov nyiaj tsis muaj kev xyuam xim nyiaj yog yaj. Cov ntsev tsis muaj ntsev uas tsis muaj zog, uas nyob hauv zaj duab xis emulsion, ua rau zaj duab xis tuaj yos daj tom qab yaug.
5. Tom qab kho cov yeeb yaj kiab tau muab tso rau hauv lub kho phij xab thaum kho, nco ntsoov them nyiaj rau txoj kev tuav pov hwm. Nws yuav tsum tau tuav lub hau kev loj hlob kom co cov kua dej, los yog tig ntxig zaj duab xis nce thiab nqis. Lub hom phiaj yog ua kom tiav cov duab ntawm cov yeeb yaj kiab thiab txhuam cov nyiaj phom sij hauv qhov kho kom haum. Yog hais tias cov duab thaij duab tso rau hauv qhov kho qhov cub, nws yuav tsis poob ntsej muag los yog sib zog. Thaum nws tsau nyob hauv ib lub xeev sawv, tsis khov kho tshwm sim, thiab residual sulfide adheres rau zaj duab xis, uas yog daj thiab xim av.
6. Teeb daj los ntawm kev ntxuav tes tom qab kho. Tom qab cov yeeb yaj kiab tag, nws yuav tsum muab tso rau hauv lub rhaub dej.
