Aluminium Sulfate
Kuyamba kwa Aluminium sulphate
Aluminium sulphate ndi mchere wokhala ndi chilinganizo cha Al2(SO4)3. Imasungunuka m'madzi ndipo imagwiritsidwa ntchito makamaka ngati coagulating wothandizira pakuyeretsa madzi akumwa ndi malo opangira madzi oyipa, komanso kupanga mapepala. Aluminium Sulphate yathu ili ndi ma granules a ufa, ma flakes, ndi mapiritsi, tithanso kupereka zopanda ferric, low-ferric, ndi mafakitale.
Aluminium sulphate imakhala yoyera, yonyezimira, magalasi, kapena ufa. M'chilengedwe, ilipo ngati mineral alunogenite. Aluminium sulphate nthawi zina amatchedwa alum kapena papermaker's alum.

Zogwiritsa Ntchito Pakhomo
Zomwe zimagwiritsidwa ntchito kwambiri ndi aluminium sulphate zimapezeka m'nyumba. Pawiriyi nthawi zambiri imapezeka mu soda, ngakhale pali mikangano ngati kuli koyenera kuwonjezera aluminium pazakudya. Ma antiperspirants ena ali ndi aluminium sulfate chifukwa cha antibacterial properties, ngakhale kuti kuyambira 2005 a FDA samazindikira kuti ndi chochepetsera mvula. Potsirizira pake, chigawocho ndi chinthu chomwe chimakhala ndi astringent mu pensulo za styptic, zomwe zimapangidwira kuletsa mabala ang'onoang'ono kuti asakhetse magazi.
Kulima dimba
Ntchito zina zosangalatsa za aluminiyamu sulphate kuzungulira nyumba ndikulima. Chifukwa aluminium sulphate ndi acidic kwambiri, nthawi zina imawonjezedwa ku dothi lamchere kwambiri kuti muchepetse pH ya zomera. Aluminiyamu sulphate ikakumana ndi madzi, imapanga aluminiyamu hydroxide ndi madzi osungunuka a sulfuric acid, omwe amasintha acidity ya nthaka. Olima omwe amabzala ma hydrangea amagwiritsa ntchito malowa kuti asinthe mtundu wamaluwa (buluu kapena pinki) wa ma hydrangeas popeza mbewuyi imakhudzidwa kwambiri ndi nthaka pH.
Chithandizo cha Aluminium SulfateWater
Chimodzi mwazofunikira kwambiri za aluminium sulphate ndikuyeretsa madzi ndi kuyeretsa. Akaphatikizidwa m'madzi, amachititsa kuti zonyansa zazing'ono kwambiri ziunjike pamodzi kukhala tinthu tating'onoting'ono tokulirapo. Zidutswa za zonyansazi zimakhazikika pansi pa chidebecho kapena kukhala zazikulu mokwanira kuti zisefe m'madzi. Izi zimapangitsa kuti madzi azikhala otetezeka kumwa. Momwemonso, aluminiyamu sulphate nthawi zina amagwiritsidwa ntchito m'mayiwe osambira kuti achepetse mtambo wamadzi.
Nsalu Zodaya
Chimodzi mwazogwiritsidwa ntchito zambiri za aluminium sulphate ndikudaya ndi kusindikiza pansalu. Ikasungunuka m'madzi ambiri omwe ali ndi pH yopanda ndale kapena yamchere pang'ono, gululi limapanga chinthu cha gooey, aluminium hydroxide. Mankhwala a gooey amathandiza utoto kumamatira kunsaluko popangitsa kuti madzi a utotowo asasungunuke. Choncho, ntchito ya aluminiyamu sulfate imakhala ngati “chokonzera utoto,” kutanthauza kuti imaphatikizana ndi kamangidwe ka maselo a utoto ndi nsalu kuti utoto usathe nsalu ikanyowa.
Kupanga Mapepala
M'mbuyomu, aluminiyamu sulphate ankagwiritsidwa ntchito popanga mapepala, ngakhale kuti zinthu zopangira zida zasintha kwambiri. Aluminiyamu sulphate anathandiza kukula kwa pepala. Pochita izi, aluminium sulphate inaphatikizidwa ndi sopo wa rosin kuti asinthe kuyamwa kwa pepala. Izi zimasintha zomwe pepala limayamwa ndi inki. Kugwiritsa ntchito aluminium sulphate kumatanthauza kuti pepalalo linapangidwa pansi pa acidic. Kugwiritsa ntchito ma synthetic sizing agents kumatanthauza kuti mapepala opanda asidi amatha kupangidwa. Pepala lopanda asidi siliphwanyika mwachangu ngati pepala lokhala ndi asidi.
