I-Aluminium Sulfate
Ukwethulwa kwe-aluminium sulfate
I-Aluminium sulfate isawoti ngefomula al2 (SO4) 3. Kuyancibilika emanzini futhi ikakhulukazi kusetshenziswa njenge-ejenti evuthayo ekuhlanzweni kwamanzi okuphuza namanzi asolwandle, futhi nasekukhiqizweni kwamaphepha. I-aluminium sulphate yethu ine-granule ye-powder, ama-flales, kanye namathebulethi, nathi singakwazi ukuhlinzeka nge-no-ferric, i-for-ferric, nebanga lezezimboni.
I-Aluminium sulfate ikhona njengezinhlanzi ezimhlophe, ezihlambalazayo, ama-granules, noma i-powder. Ngokwemvelo, ikhona njenge-alunogenite yamaminerali. I-Aluminium sulfate kwesinye isikhathi ibizwa nge-alum noma i-papermaker's alum.

Ukusetshenziswa kwasendlini
Okunye ukusetshenziswa okuvame kakhulu kwe-aluminium sulfate kutholakala ngaphakathi kwekhaya. I-Compound ivame ukutholakala ku-baking soda, yize kunempikiswano ethile yokuthi kufanelekile ukwengeza i-aluminium ekudleni. Amanye ama-antiperspirants aqukethe i-aluminium sulfate ngenxa yezakhiwo zayo ze-antibacterial, yize kusukela ngo-2005 i-FDA ayikuboni njenge-WETENSER Ekugcineni, i-Compound isithako se-astringent kumapensela esitayela, aklanyelwe ukumisa ukusikeka okuncane ekujuleni kokopha.
Ukusebenza engadini
Okunye ukusetshenziswa okuthokozisayo kwe-aluminium sulfate ezungeze indlu kusegadi. Ngoba i-aluminium sulfate i-acidic kakhulu, kwesinye isikhathi ingezwe emhlabathini we-alkaline kakhulu ukulinganisa i-pH yezitshalo. Lapho i-aluminium sulfate ihlangana namanzi, yakha i-aluminium hydroxide kanye nesixazululo se-sulfuric acid esihlanjululwe, esiguqula i-acidity yenhlabathi. Abalimi abatshala ama-hydrangeas basebenzisa le mpahla ukushintsha umbala wezimbali (oluhlaza okwesibhakabhaka noma opinki) we-hydrangeas selokhu lesi sitshalo sizwela kakhulu inhlabathi pH.
I-Aluminium Sulfatewater Ukwelashwa
Okunye ukusetshenziswa okubaluleke kakhulu kwe-aluminium sulfate kukwelashwa kwamanzi nasekuhlanzeni. Uma kungezwe emanzini, kubangela ukungcola okuyi-microscopic ukuba kuqubuke ndawonye kube izinhlayiya ezinkulu nezinkulu. Lezi zinhlaka zokungcola ziyobe sezizwakala ezansi kwesitsha noma okungenani zikhulu ngokwanele ukuba zihlunge ngaphandle kwamanzi. Lokhu kwenza amanzi aphephe ukuphuza. Ngokomthetho ofanayo, i-aluminium sulfate nayo kwesinye isikhathi isetshenziswa emachibini okubhukuda ukunciphisa amafu amanzi.
Izindwangu zokudaya
Okunye kokusetshenziswa okuningi kwe-aluminium sulfate kukudaya nokuphrinta ngendwangu. Lapho incibilika ngenani elikhulu lamanzi ane-neutral noma i-alkaline ph ph, i-compound ikhiqiza into ye-gooey, i-aluminium hydroxide. I-Gooey Into isiza amadayi anamathela kumicu yendwangu ngokwenza i-Dye WAMINE DEWLUBLE. Iqhaza le-aluminium sulfate,-ke, linjengedayi "elikulungile," okusho ukuthi lihlanganisa nokwakheka kwedayi kanye nendwangu ngakho-ke udayi uphela lapho indwangu iba manzi.
Ukwenza amaphepha
Esikhathini esedlule, i-aluminium sulfate yasetshenziswa ephepheni, yize ama-zonthetic agents athathe indawo yawo. I-aluminium sulfate yasiza ngosayizi wephepha. Kule nqubo, i-aluminium sulfate yahlanganiswa ne-rosin insipho yokushintsha ukukhishwa kwephepha. Lokhu kushintsha izakhiwo ezithinta inki ephepheni. Sebenzisa i-aluminium sulfate kusho ukuthi iphepha lenziwe ngaphansi kwezimo ze-acid. Ukusetshenziswa kwama-ejenti wezandla zokwenziwa kusho ukuthi iphepha elingena-acid liyakhiqizwa. Iphepha elinama-acid-free alishidi ngokushesha njengephepha elilinganiswe ne-acid.
