I-aluminium sulfate
Ukwethulwa kwe-Aluminium sulfate
I-Aluminium sulfate ingusawoti onefomula ethi Al2(SO4)3.Iyancibilika emanzini futhi isetshenziswa ikakhulukazi njenge-ejenti ehlanganisayo ekuhlanzweni kwamanzi okuphuza nezitshalo zokuhlanza amanzi angcolile, kanye nasekukhiqizeni amaphepha.I-Aluminium Sulphate yethu inama-powder granules, ama-flakes, namaphilisi, futhi singahlinzeka nge-no-ferric, i-low-ferric, kanye nebanga lezimboni.
I-aluminium sulfate ikhona njengamakristalu amhlophe, acwebezelayo, ama-granules, noma impushana.Emvelweni, ikhona njenge-alunogenite yamaminerali.I-aluminium sulfate ngezinye izikhathi ibizwa ngokuthi i-alum noma i-papermaker's alum.

Ukusetshenziswa Kwasekhaya
Ezinye zezinto ezivame ukusetshenziswa kakhulu ze-aluminium sulfate zitholakala ngaphakathi kwekhaya.I-compound ivame ukutholakala ku-baking soda, nakuba kukhona impikiswano mayelana nokuthi kufanelekile yini ukwengeza i-aluminium ekudleni.Amanye ama-antiperspirants aqukethe i-aluminium sulfate ngenxa yezakhiwo zayo zokulwa namagciwane, nakuba kusukela ngo-2005 i-FDA ingayiboni njengento enciphisa ukumanzi.Ekugcineni, inhlanganisela iyisithako esine-astringent kumapensela okubhala, aklanyelwe ukunqanda ukusikeka okuncane ekopheni.
Ukulima
Okunye ukusetshenziswa okuthokozisayo kwe-aluminium sulfate ezungeze indlu kusengadini.Ngenxa yokuthi i-aluminium sulfate ine-acidic ngokwedlulele, ngezinye izikhathi yengezwa enhlabathini ene-alkaline ukulinganisa i-pH yezitshalo.Lapho i-aluminium sulfate ihlangana namanzi, yenza i-aluminium hydroxide kanye nesisombululo se-sulfuric acid ehlanjululwe, esishintsha ubumuncu bomhlaba.Abalimi abatshala ama-hydrangea basebenzisa lesi sakhiwo ukushintsha umbala wembali (oluhlaza okwesibhakabhaka noma obomvana) we-hydrangeas njengoba lesi sitshalo sizwela kakhulu enhlabathini pH.
I-Aluminium SulfateWater Treatment
Okunye okubaluleke kakhulu ukusetshenziswa kwe-aluminium sulfate ekwelashweni nasekuhlanzweni kwamanzi.Uma yengezwe emanzini, yenza ukungcola okungabonakali kuhlangane ndawonye kube izinhlayiya ezinkulu nezikhudlwana.Lezi zigaxa zokungcola zizobe sezihlala phansi kwesiqukathi noma okungenani zibe zinkulu ngokwanele ukuba ziwacwenge aphume emanzini.Lokhu kwenza amanzi aphephe nakakhulu ukuwaphuza.Ngaso lesi simiso, i-aluminium sulfate ngezinye izikhathi isetshenziswa emachibini okubhukuda ukuze kwehliswe ukuguqubala kwamanzi.
Izindwangu Zokudaya
Okunye ukusetshenziswa okuningi kwe-aluminium sulfate ukudaya nokuphrinta endwangwini.Uma incibilika emanzini amaningi ane-pH engathathi hlangothi noma ene-alkaline kancane, isakhi samakhemikhali sikhiqiza i-gooey substance, i-aluminium hydroxide.I-gooey substance isiza odayi ukuthi banamathele emicu yendwangu ngokwenza ukuthi amanzi odayi angancibiliki.Ngakho-ke, indima ye-aluminium sulfate ifana “nesilungisi” sikadayi, okusho ukuthi ihlanganisa ukwakheka kwamangqamuzana odayi nendwangu ukuze udayi ungaqedi lapho indwangu isimanzi.
Ukwenza Amaphepha
Esikhathini esidlule, i-aluminium sulfate yayisetshenziswa ekwenzeni iphepha, nakuba ama-synthetic agents aye athatha indawo yawo.I-aluminium sulfate yasiza ubukhulu bephepha.Kule nqubo, i-aluminium sulfate yahlanganiswa nensipho ye-rosin ukushintsha ukumuncwa kwephepha.Lokhu kushintsha izici zokumunca uyinki zephepha.Ukusebenzisa i-aluminium sulfate kusho ukuthi iphepha lenziwe ngaphansi kwezimo ezine-acidic.Ukusetshenziswa kwama-synthetic sizing agents kusho ukuthi iphepha elingenayo i-asidi lingakhiqizwa.Iphepha elingenayo i-asidi aliqhekeki ngokushesha njengephepha elilingana ne-asidi.
