Thaum xaiv polyaluminum chloride (PAC), nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus tseem ceeb hauv qab no kom ntseeg tau tias cov khoom xaiv tau raws li qhov yuav tsum tau ua ntawm daim ntawv thov thiab cov qauv kev cai hauv zos:
- Cov ntsiab lus ntawm aluminium hydroxide (Al2O3 cov ntsiab lus):PAC cov khoom feem ntau yog sawv cev los ntawm cov ntsiab lus ntawm aluminium hydroxide (Al2O3), uas yog ib qho tseem ceeb rau kev ntsuas cov khoom purity thiab kev ua haujlwm. Cov ntsiab lus siab alumina feem ntau qhia tau hais tias muaj kev purity ntau dua ntawm cov khoom, uas tuaj yeem muab cov dej ua kom zoo dua qub.
- Basicity:Lub hauv paus ntawm PAC yog hais txog nws lub peev xwm kom muaj hydroxyl ions (OH -), uas yog alkalinity ntawm cov khoom. Cov qib sib txawv ntawm PAC yog tsim rau cov dej zoo sib txawv, feem ntau ntawm 5% thiab 90%. Xaiv ib theem tsim nyog ntawm PAC tuaj yeem hloov kho kom zoo rau cov dej zoo.
- Cov ntsiab lus hlau (Fe):Cov ntsiab lus hlau siab PAC tuaj yeem ua rau cov dej tsis zoo, yog li nws feem ntau yuav tsum xaiv cov khoom uas muaj cov ntsiab lus hlau qis, tshwj xeeb tshaj yog rau kev kho dej haus.
Cov ntsiab lus insolubles yog hais txog impurities thiab cov khoom seem hauv PAC uas tsis tuaj yeem yaj hauv dej. Cov dej insoluble cov ntsiab lus ntawm cov khoom yuav tsum tsawg kom ntseeg tau tias tsis muaj cov pa phem ntxiv thaum siv.
- Particle Loj:Qhov loj me me ntawm PAC cov khoom cuam tshuam rau lawv qhov kev sib cais thiab sib xyaw ua ke hauv dej. Xaiv cov khoom uas tsim nyog particle loj tuaj yeem pab txhim kho tus nqi sib tov thiab dej purification nyhuv.
- Solubility:Solubility ntawm PAC yog hais txog nws qib ntawm solubility hauv dej. Cov khoom uas muaj siab solubility feem ntau yog yooj yim dua soluble nyob rau hauv dej, muab cov dej purification zoo dua.
- Cov txheej txheem ntau lawm thiab daim ntawv pov thawj zoo:Xav txog kev xaiv cov khoom lag luam nrog lub koob npe zoo thiab ua tau raws li cov qauv zoo los ntawm cov chaw tsim khoom rooj tog. Cov khoom yuav tsum ua raws li cov qauv hauv lub tebchaws lossis cheeb tsam thiab tuaj ntawm cov tuam txhab ntseeg siab.
Thaum xaiv cov khoom tsim nyog PAC, nws yog qhov zoo tshaj plaws los sab laj tus kws tshaj lij kev kho dej lossis tus kws tshaj lij dej kom ua tau raws li cov kev xav tau ntawm cov dej zoo thiab kev kho mob, kom ntseeg tau tias cov khoom xaiv tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws hauv ib puag ncig tshwj xeeb. .
Yog tias koj muaj ib qhov project koj xav sib tham, lossis koj xav tau kev txhawb nqa thiab kev pab cuam; lossis yog tias koj tsuas muaj lus nug txog PAC, thov hu rau peb.
