ISICELO SOKUCOCA AMANZI
Ngaba ukhe wazibuza ukuba siyakwazi njani ukuba namanzi okusela akhuselekileyo aphuma kwiimpompo zethu? Ungabulela i-aluminium sulfate. Ababoneleli bamanzi bakamasipala, njengenkampani yakho yamanzi yasekuhlaleni, basebenzisa i-alum ukunyanga amanzi asetyenziswa ngabantu. Ukongeza, amanzi acutshungulwayo (amanzi angaselwayo) anokunyangwa ngale khemikhali ukuze acocwe xa iintsholongwane/inkunkuma inokubangela isiphumo esibi.
Xa ifakwa emanzini, i-aluminium sulfate ibangela ukuba ukungcola okuncinci kuhlangane kube ngamasuntswana amakhulu namakhulu. La masuntswana ahlala ezantsi kwesikhongozeli aze ahluzwe. Oku kwenza amanzi akhuseleke ngakumbi ukuselwa. Ngomgaqo ofanayo, i-alum ngamanye amaxesha isetyenziswa emachibini okubhukuda ukunciphisa ukufiphala kwamanzi (6).
AMALAPHU OKUDAYA
Jonga phantsi ihempe yakho. Kusenokwenzeka ukuba ayiyo-t-shirt emhlophe nje. Enye yeendlela ezininzi zokusebenzisa i-Aluminium sulfate kukudaya nokuprinta elaphini. Xa inyibilikisiwe emanzini amaninzi ane-pH engathathi cala okanye ene-alkaline kancinci, le compound ivelisa into egooey, i-Aluminium hydroxide. Le goo inceda iidayi ukuba zinamathele kwimicu yelaphu ngokwenza amanzi edayi anganyibiliki. Indima ye-Aluminium sulfate, ke ngoko, kukuba “i-fixer” yedayi, oko kuthetha ukuba idibana nesakhiwo se-molecular yedayi kunye nelaphu ukuze idayi ingaphelelwa xa ilaphu limanzi (6).
UKWENZA IPHEPHA
Ngaphambili, i-aluminium sulfate yayisetyenziswa ekwenzeni iphepha, nangona ii-synthetic agents zazilithatha indawo yalo kakhulu. I-aluminium sulfate inceda ekulinganiseni iphepha. Kule nkqubo, idityaniswa ne-rosin seap ukutshintsha ukufunxwa kwephepha, nto leyo etshintsha iipropati zokufunxa i-inki yephepha. I-aluminium sulfate ivelisa iimeko ze-asidi, ngelixa ii-synthetic sizeing agents zivelisa iphepha elingena-asidi elingaqhekekiyo lula (6).
ISICELO SEZONYANGO
Ukuya eofisini kagqirha akuyonto imnandi, kodwa ngenxa ye-aluminium sulfate, icandelo lezonyango liye lakwazi ukuhambela phambili ngeendlela ezahlukeneyo ukuze sihlale siphilile. I-aluminium sulfate ineendlela ezininzi ezisebenzayo kwicandelo lezonyango. Isetyenziswa kakhulu njenge-arhente yokujiya ekunyangeni amanxeba amancinci kunye nokukrweleka kunye ne-deodorant (ngenxa yeempawu zayo zokulwa ne-antibacterial). Le khompawundi ikwafunxa kwaye ikhuphe ii-antigens zeproteni kwisisombululo; ukuncipha okubangelwayo kuphucula ukuqina kwe-vaccine ngokuncedisa ukukhululwa kancinci kwe-antigen kwindawo yokugonya eyenziwe kwindawo yokugonya (1). Izisombululo ezine-5 ukuya kwi-10% zisetyenzisiwe njengezicelo zasekuhlaleni kwizilonda kunye nokuthintela ukuphuma okungcolileyo kumphezulu we-mucous (2). I-aluminium sulfate ifumaneka kwizinto ezisetyenziswa kwishishini lezonyango. Umzekelo, isetyenziswa ekulungiseleleni amaconsi endlebeni ye-aluminium acetate (2).
ISICELO SOMSHINI WOKUTYA
I-Alum isetyenziselwa iinjongo ezininzi ekutyeni esikutyayo kwaye ngokubanzi ibonwa njengekhuselekileyo xa isetyenziswa ngokwemigaqo yokwenziwa kakuhle (2). Iyanyibilika emanzini kwaye isetyenziswa kakhulu njenge-thickener kunye ne-emulsifier (3).
I-Alum ingasetyenziselwa:
- Hlaziya kwaye ucacise amanzi ukuze ufumane iziselo ezibandayo kunye nebhiya
- Lawula amanqanaba e-pH kwi-beet, iitumato, kunye neminye imifuno
- Ukucocwa kweejusi zebeet zeswekile
- Lawula i-pH kunye nombala wewayini kunye notywala
- Sebenzisa njengesixhobo sokugaya igwele kumxube wekhekhe (i-baking soda)
- Itshizi eyojiweyo netshizi eyojiweyo (4).
