Aluminium Sulfate
Kev Taw Qhia Txog Aluminium sulfate
Aluminium sulfate yog ib hom ntsev uas muaj cov mis Al2(SO4)3. Nws yaj tau hauv dej thiab feem ntau yog siv los ua cov tshuaj coagulating hauv kev ntxuav cov dej haus thiab cov chaw kho dej khib nyiab, thiab tseem siv rau hauv kev tsim ntawv. Peb cov Aluminium Sulfate muaj cov hmoov granules, flakes, thiab ntsiav tshuaj, peb kuj tuaj yeem muab cov khoom tsis muaj ferric, low-ferric, thiab qib kev lag luam.
Aluminium sulfate muaj nyob rau hauv cov xim dawb, ci ntsa iab, granules, lossis hmoov. Nyob rau hauv xwm, nws muaj nyob rau hauv cov mineral alunogenite. Aluminium sulfate qee zaum hu ua alum lossis papermaker's alum.

Kev Siv Hauv Tsev Neeg
Qee qhov kev siv ntau tshaj plaws ntawm txhuas sulfate pom muaj nyob hauv tsev. Cov tshuaj no feem ntau pom muaj nyob rau hauv baking soda, txawm hais tias muaj qee qhov kev tsis sib haum xeeb txog seb nws puas tsim nyog ntxiv txhuas rau hauv cov zaub mov noj. Qee cov tshuaj tiv thaiv hws muaj txhuas sulfate vim nws cov khoom tua kab mob, txawm hais tias txij li xyoo 2005 FDA tsis lees paub nws ua cov tshuaj txo qhov ntub. Thaum kawg, cov tshuaj no yog cov khoom xyaw astringent hauv cov cwj mem styptic, uas tau tsim los tiv thaiv cov qhov me me los ntawm kev los ntshav.
Kev ua teb
Lwm yam kev siv aluminium sulfate nyob ib puag ncig lub tsev yog kev ua teb. Vim tias aluminium sulfate muaj kua qaub heev, qee zaum nws raug ntxiv rau hauv cov av alkaline heev kom sib npaug pH ntawm cov nroj tsuag. Thaum aluminium sulfate kov dej, nws tsim cov txhuas hydroxide thiab cov kua sulfuric acid diluted, uas hloov cov kua qaub ntawm cov av. Cov neeg ua teb uas cog hydrangeas siv cov khoom no los hloov xim paj (xiav lossis liab) ntawm hydrangeas vim tias cov nroj tsuag no rhiab heev rau pH av.
Kev Kho Dej Aluminium Sulfate
Ib qho tseem ceeb tshaj plaws ntawm kev siv txhuas sulfate yog hauv kev kho dej thiab kev ntxuav. Thaum ntxiv rau hauv dej, nws ua rau cov khoom tsis huv me me sib sau ua ke ua cov khoom loj dua thiab loj dua. Cov khoom tsis huv no yuav poob rau hauv qab ntawm lub thawv lossis tsawg kawg loj txaus los lim lawv tawm ntawm cov dej. Qhov no ua rau cov dej haus muaj kev nyab xeeb dua. Raws li tib lub hauv paus ntsiab lus, txhuas sulfate kuj qee zaum siv hauv cov pas dej ua luam dej kom txo qhov tsis huv ntawm cov dej.
Cov Ntaub Xim
Lwm yam uas siv tau ntawm txhuas sulfate yog siv rau kev zas xim thiab luam ntawv rau ntawm daim ntaub. Thaum yaj rau hauv dej ntau uas muaj pH nruab nrab lossis me ntsis alkaline, cov tshuaj no tsim cov khoom nplaum, txhuas hydroxide. Cov khoom nplaum no pab cov xim lo rau cov ntaub los ntawm kev ua rau cov dej xim tsis yaj. Yog li ntawd, lub luag haujlwm ntawm txhuas sulfate yog ua tus "kho xim," uas txhais tau tias nws sib xyaw nrog cov qauv molecular ntawm cov xim thiab daim ntaub kom cov xim tsis khiav tawm thaum daim ntaub ntub.
Kev Ua Ntawv
Yav dhau los, cov txhuas sulfate tau siv los ua ntawv, txawm hais tias cov tshuaj synthetic feem ntau tau hloov nws. Cov txhuas sulfate tau pab rau qhov loj ntawm daim ntawv. Hauv cov txheej txheem no, txhuas sulfate tau muab sib xyaw nrog xab npum rosin los hloov qhov nqus ntawm daim ntawv. Qhov no hloov cov yam ntxwv ntawm daim ntawv nqus kua mem. Siv cov txhuas sulfate txhais tau tias daim ntawv tau ua nyob rau hauv cov xwm txheej acidic. Kev siv cov tshuaj synthetic sizing txhais tau tias daim ntawv tsis muaj kua qaub tuaj yeem tsim tau. Daim ntawv tsis muaj kua qaub tsis tawg sai li daim ntawv nrog kua qaub.
