Aluminium sulfate
Kuyambitsa aluminium sulfate
Aluminium sulfate ndi mchere wokhala ndi formula al2 (so4) 3. Imasungunuka m'madzi ndipo imagwiritsidwa ntchito ngati wothandizira wothandizira kumwa madzi ndikuthirira madzi ndipo imathirira madzi ndikuchizira zinyalala, komanso kupanga mapepala. Mafuta athu a allaminiyamu athu ali ndi ma granules a ufa, flakes, ndi mapiritsi, ifenso titha kupezanso achangu, opanda mphamvu, ndi mafakitale.
Aluminium sulfate ulipo ngati makhiristu, mabwalo, kapena ufa. Mwachilengedwe, imakhalapo ngati mchere alunigenite. Aluminium sulfate nthawi zina amatchedwa alum kapena pepakeka.

Ntchito zapakhomo
Zina mwazomwe zimagwiritsidwa ntchito kwambiri za aluminium sulfate zimapezeka mnyumba. Pawiri imapezeka kawirikawiri mu soda, ngakhale pali mikangano yambiri ngati ili yoyenera kuwonjezera aluminium ndikudya. Ena antinorpirants sulfate chifukwa cha antibacterial katundu, ngakhale ngati 2005 FDA sazindikira kuti ngati kunyowa. Pomaliza, pawiri ndi yofunika kwambiri mu mapensulo a masitaloti a masitaloti, omwe amapangidwa kuti athe kuyimitsa maulendo ang'onoang'ono kuti asatuluke magazi.
Ulimi
Zogwiritsanso ntchito zina za aluminiyam sulfate mozungulira nyumbayo muli dimba. Chifukwa aluminium sulfate ndi acidic kwambiri, nthawi zina amawonjezeredwa kwambiri ndi dothi la nsomba kuti muchepetse pH ya mbewu. Pamene aluminium sulfate imalumikizana ndi madzi, imapanga aluminium hydroxide ndi sulfuric acid yankho, lomwe limasintha nthaka. Wolima wamaluwa omwe amabzala hydradeon amagwiritsa ntchito malowa kuti asinthe mtundu wa maluwa (buluu kapena pinki) wa hydrazeas kuyambira pomwe mbewuyi imakhudzidwa kwambiri ndi dothi PH.
Aluminium sulfateter chithandizo
Chimodzi mwazinthu zofunika kwambiri za aluminium sulfate uli mu chithandizo chamadzi ndi kuyeretsa. Mukawonjezera madzi, zimayambitsa microscopic to clump pamodzi ndi ma tinthu tating'onoting'ono. Izi zimakhazikika pansi pa chidebe kapena kukhala okulirapo kuti ziwasemeza m'madzi. Izi zimapangitsa kuti madzi akhale otetezeka kumwa. Pamlingo womwewo, aluminium sulpate nthawi zina amagwiritsidwanso ntchito posambira m'madziwe osambira kuti achepetse mitambo yamadzi.
Zovala Zovala
Imodzi mwazomwe zimagwiritsidwa ntchito mwamphamvu za aluminiyamu sulfate ili mu utoto ndi kusindikiza nsalu. Mukasungunuka m'madzi ambiri omwe ali ndi vuto la PH kapena pang'ono alkalinel. Zinthu za gooey zimathandiza kuti utoto umagwirizanitsa nsalu popanga utoto. Udindo wa aluminiyamu sulfate, ndiye, ili ngati utoto "wokonza," zomwe zikutanthauza kuti imaphatikizira ndi mawonekedwe a utoto wa utoto ndi nsalu kuti utoto sungunuka pomwe nsaluyo imanyowa.
Kupanga pepala
M'mbuyomu, aluminium sulfate adagwiritsidwa ntchito popanga pepala, ngakhale kuti othandizira adasintha kwambiri. Aluminium sulfate adathandizira kukula kwa pepalalo. Munjira imeneyi, aluminium sulfate adaphatikizidwa ndi sosin sopo kuti asinthe kuyamwa kwa pepalalo. Izi zimasintha katundu wa mapepala. Kugwiritsa ntchito aluminium sulfate kumatanthauza kuti pepalali lidapangidwa pansi pa acidic mikhalidwe. Kugwiritsa ntchito mankhwala opatsirana kumatanthauza kuti mapepala opanda asidi akhoza kupangidwa. Pepala lopanda ma acid silimathwa mwachangu ngati pepala lokhala ndi asidi.
