Vim li cas Sodium Sulphate Whiteness thiaj tseem ceeb hauv kev siv hauv kev lag luam?
Thaum nrhiav cov tshuaj inorganic rau kev tsim khoom, cov neeg yuav khoom hauv kev lag luam feem ntau yuav tsum muab qhov tseem ceeb rau lawv. kev ntshiab ntawm tshuaj lom neeg (feem pua ntawm kev sim)tshaj txhua yam. Rau Sodium Sulfate Anhydrous (tsis muaj dej)Qhov ntawd2Yog li ntawd4 ), tau txais qib kev huv ntawm 99% lossis siab dua yog qhov yuav tsum tau ua. Txawm li cas los xij, cov thawj coj cog khoom uas muaj kev paub dhau los, cov kws tshaj lij kev lees paub zoo, thiab cov kws ua haujlwm yuav khoom paub tias kev nthuav qhia lub cev - tshwj xeeb dawb thiab qhov kaj ntawm lub qhov muag—ua haujlwm ua ib qho cim qhia tseem ceeb ntawm qhov zoo ntawm cov khoom siv.
Qhov dawb uas pom tau tsis yog tsuas yog xav txog qhov zoo nkauj xwb. Hauv kev siv hauv kev lag luam, kev hloov pauv ntawm cov ntsuas dawb qhia ncaj qha txog kev ua qias tuaj ntawm cov tshuaj lom neeg me me, qhov zoo ntawm kev ua kom huv, thiab tej yam txaus ntshai thaum lub sijhawm ua cov txheej txheem tom qab.
1. Dab tsi ua rau muaj kev hloov pauv ntawm qhov dawb ntawm Sodium Sulphate?
Cov sodium sulphate ntshiab yog ib hom hmoov crystalline dawb uas tsis muaj xim lossis ci ntsa iab. Thaum cov khoom lag luam muaj cov xim daj, greyish, lossis dawb tawm, nws qhia tias muaj cov khoom tsis huv me ntsis lossis cov xwm txheej ua tsis zoo:
- Cov Hlau Hnyav Me Me (Hlau thiab Manganese): Txawm tias qhov sib xyaw ua ke ntawm cov ferric oxide me me (Fe)2TUS3), feem ntau ntsuas hauv ib feem ntawm ib lab (ppm), ua rau muaj xim daj lossis xim av rau cov hmoov tshuaj lom neeg loj.
- Cov Khoom Siv Organic Uas Tsis Yaj Tau: Cov pob zeb ntsev ntuj lossis cov pob zeb mirabilite feem ntau muaj cov organic trace elements. Kev hlawv tsis tiav qhov kub ua rau muaj cov khoom me me uas ua rau lub teeb ci ntsa iab.
- Cov Ntsiab Lus Nqus Dej & Kev Sib Xws ntawm Cov Khoom Me Me: Qhov loj ntawm cov noob tsis sib xws thiab cov dej noo ntau dhau ntawm qhov chaw ua rau lub teeb tsis sib xws, ua rau cov khoom zoo li tsis ci, xim grey, lossis clumpy.
2. Qhov Dawb Cuam Tshuam Li Cas rau Cov Chaw Lag Luam Tseem Ceeb
A. Kev Tsim Cov Tshuaj Ntxuav Khaub Ncaws
Hauv cov hmoov tshuaj ntxuav tes, cov sodium sulphate anhydrous ua haujlwm ua tus neeg tseem ceeb rau kev sau thiab ua kom cov dej ntws zoo, ua ib feem tseem ceeb ntawm tag nrho cov khoom. Cov neeg siv khoom feem ntau xav tias cov hmoov dawb dawb yog qhov huv heev. Kev siv sodium sulphate uas muaj cov ntsuas dawb qis dua tuaj yeem ua rau cov khoom tiav tsaus ntuj, ua rau cov chaw tsim khoom yuav tsum ntxiv cov tshuaj ci ntsa iab kim dua los them rau.
B. Kev Xim Xim thiab Kev Sib Xws ntawm Cov Ntaub
Hauv kev zas xim paj rwb thiab cellulose ntaub, sodium sulphate ua haujlwm ua cov ntsev electrolyte (dyeing accelerator) uas yuam cov xim reactive tawm ntawm cov kua dej thiab mus rau ntawm cov ntaub textile. Cov hlau hnyav impurities (xws li cov hlau ions) uas cuam tshuam nrog qhov dawb tsis zoo tuaj yeem cuam tshuam nrog cov molecules zas xim rhiab heev, ua rau cov xim hloov pauv, cov xim nag ua ntej, lossis kev faib xim tsis sib xws thoob plaws hauv cov pawg.
C. Kev Tsim Kho Iav (Iav Tiaj thiab Iav Thawv)
Sodium sulphate ua haujlwm ua tus neeg sawv cev zoo hauv kev tsim iav, pab tshem tawm cov npuas huab cua me me hauv lub cub tawg yaj. Thaum cov qib dawb qis uas muaj cov hlau oxides siv, cov khoom tsis huv no hloov pauv qhov pom tseeb thiab xim ntawm cov iav thawv lossis cov iav architectural float.
3. Sib piv cov qib dawb thiab kev siv tau zoo

| Cov hlau hnyav ntau dua, cov khoom tsis yaj tau hloov pauv | Cov tshuaj lom neeg yooj yim, cov khoom siv ntxiv rau kev tsim kho, cov khoom siv rau kev lag luam |
4. Cov Qauv Tswj Xyuas Kev Zoo rau Kev Yuav Khoom
Yuav kom tiv thaiv tau qhov zoo ntawm kev tsim khoom, cov neeg yuav tshuaj lom neeg yuav tsum suav nrog cov lus qhia meej meej rau hauv lawv daim ntawv teev npe yuav khoom nrog rau feem pua ntawm kev huv:
1.R457 Kev Ntsuas Qhov Ci:Siv cov kev ntsuas spectrophotometric los xyuas kom meej tias qhov kaj pom kev sib xws thoob plaws cov khoom xa tuaj.
2.Cov Hlau (Fe PPM):Ua qhov kev sim ICP-OES kom paub tseeb tias cov hlau ions tseem nyob hauv qab qhov txwv ua haujlwm tseem ceeb.
3.Cov Khoom Uas Tsis Yaj Hauv Dej:Xyuas kom meej tias cov ntsiab lus uas tsis yaj tau tseem nyob hauv qab qhov txwv nruj (
