1. Cov neeg sawv cev nrawm-teeb tsa feem ntau tsim ntawm txhuas sulfate
Lub luag haujlwm tseem ceeb ntawm kev ua haujlwm nrawm hauv tus neeg sawv cev no yog Aluminium ions. Txawm li cas los xij, vim muaj solubility qis ntawm txhuas sulfate, cov kev daws teeb meem tsis ruaj khov, thiab feem ntau muaj lub zog thaum ntxov, thiab lub zog poob qis hauv cov theem tom ntej.
2. Cov neeg sawv cev nrawm nrawm feem ntau tsim ntawm txhuas sulfate thiab sodium aluminate
Aluminium sulfate thiab sodium aluminate tuaj yeem hnov mob hauv qab qee yam kev mob los tsim cov polymeric aluminium sulfate, uas nce cov ntsiab lus txhuas hauv kev daws. Txawm li cas los xij, kev ruaj ntseg ntawm polymeric aluminium sulfate yog tsis zoo, thiab tam sim no, stabilizes thiab tam sim no siv los tswj cov ions aluminium ions, txuas lawv lub sijhawm cia. Tus neeg saib xyuas kev yoo mov muaj qhov tsawg tshaj plaws rau lub zog tom qab ntawm lub zog ntawm xis mas thiab yog zoo rau ntau hom ntawm cov xis. Txawm li cas los xij, cov lus qhia ntxiv, ntxiv rau sodium aluminate primitably qhia cov qauv ntawm cov neeg sawv cev ntawm kev ua kom alkali.
3. Cov neeg sawv cev nrawm-teeb tsa feem ntau tsim ntawm txhuas sulfate thiab txhuas hydroxide
Aluminium Sulfate thiab Aluminium hydroxide tuaj yeem hloov pauv ncaj qha los tsim cov txheej txheem aluminium, uas ua ntej cov tshuaj tiv thaiv cov tshuaj tiv thaiv, thaum qhia txog kev coj ua Aluminium ions. Qhov zoo dua yog tias nws tsis qhia alkali hlau ions, tab sis qhov kev sib tw ntawm txhuas hydroxide thiab cov ua kom muaj zog, thiab tsis muaj txiaj ntsig zoo rau lub sijhawm ntev thiab siv.
4. Cov tshuaj tiv thaiv ceev-teeb tsa los ntawm kev sib txuas ua ke txhuas sulfate nrog lwm cov khoom
Aluminium sulfate kuj tseem tuaj yeem ua ke nrog sodium fluoride, magnesium sulfate, thiab lwm yam, los ua tus neeg sawv cev ceev-chaw. Txawm li cas los xij, ob qho tib si sodium fluoride thiab magnesium sulfate muaj qee cov drawbacks. Piv txwv li, sodium fluoride tuaj yeem txhawb kev tsim cov khoom siv ntawm cov ceg xis, thiab txhim kho kev ruaj khov, ua rau muaj kev ruaj ntseg ntawm aluminium ions kua txiv. Txawm li cas los xij, lub drawback yog tias nws qhia alkali hlau ions. Magnesium sulfate tuaj yeem txhim kho lub zog thaum ntxov thiab txhim kho qhov kev hloov pauv ntawm cov khoom noj kom haum rau cov txiv ntseej ntawm cov pob zeb ntau dhau, txo qhov tsis muaj zog.
