IZINTO ZOKWENZA NGOKUPHATHA AMANZI
Wake wazibuza ukuthi sikwazi kanjani ukuthola amanzi okuphuza aphephile ephuma empompini zethu? Ungabonga i-aluminium sulfate. Abaphakeli bamanzi bakamasipala, njengenkampani yakho yasendaweni yokusetshenziswa kwamanzi, basebenzisa i-alum ukwelapha amanzi asetshenziswa ngabantu. Ngaphezu kwalokho, amanzi okucubungula (amanzi angaphuzwayo) nawo angase aphathwe ngaleli khemikhali ukuze ahlanzwe lapho amabhaktheriya/indle ingabangela umphumela omubi.
Uma ifakwa emanzini, i-aluminium sulfate ibangela ukungcola okuncane kakhulu ukuthi kuhlangane kube yizinhlayiya ezinkulu nezinkulu. Lawa maqoqo abe esehlala phansi kwesitsha futhi angahlungwa. Lokhu kwenza amanzi aphephe ukuwaphuza. Ngendlela efanayo, i-alum ngezinye izikhathi isetshenziswa emachibini okubhukuda ukunciphisa ukufiphala kwamanzi (6).
IZINDLA ZOKUDAYA
Bheka phansi ihembe lakho. Cishe akuyona ihembe elimhlophe elivamile. Okunye kokusetshenziswa okuningi kwe-Aluminium sulfate ukudaya nokuphrinta endwangu. Uma incibilikiswa emanzini amaningi ane-pH engathathi hlangothi noma ene-alkaline kancane, inhlanganisela ikhiqiza into egobile, i-Aluminium hydroxide. Le goo isiza amadayi ukuthi anamathele emicu yendwangu ngokwenza amanzi edayi angancibiliki. Indima ye-Aluminium sulfate,-ke, iwukuba “isilungisi” sedayi, okusho ukuthi ihlangana nesakhiwo sama-molecule sedayi kanye nendwangu ukuze idayi ingapheli lapho indwangu imanzi (6).
UKWENZA IPHEPHA
Esikhathini esidlule, i-aluminium sulfate yayisetshenziswa ekwenzeni iphepha, yize izinto zokwenziwa zazilishintsha kakhulu. I-aluminium sulfate iyasiza ekulinganiseni iphepha. Kule nqubo, ihlanganiswa nensipho ye-rosin ukushintsha ukumuncwa kwephepha, okushintsha izakhiwo zokumunca uyinki wephepha. I-aluminium sulfate ikhiqiza izimo ze-acidic, kanti izinto zokwenziwa zokulinganisa zikhiqiza iphepha elingena-acid elingaqhekeki kalula (6).
IZICELO ZEZEMPILO
Ukuya ehhovisi likadokotela akukaze kube mnandi, kodwa ngenxa ye-aluminium sulfate, insimu yezokwelapha ikwazile ukuthuthuka ngezindlela eziningana ukuze isigcine siphilile. I-aluminium sulfate inezindlela eziningana ezisebenzayo emkhakheni wezokwelapha. Isetshenziswa ngokuyinhloko njenge-ejenti yokubopha ekwelapheni ukusikeka okuncane kanye nokuhuzuka kanye ne-deodorant (ngenxa yezakhiwo zayo zokulwa namagciwane). Le nhlanganisela imunca futhi ibangele ama-antigen amaprotheni esixazululweni; ukushesha okubangelwayo kuthuthukisa ukuzivikela komzimba ngokugoma ngokwenza kube lula ukukhishwa kwe-antigen kancane endaweni yokugoma eyakhiwe endaweni yokugoma (1). Izixazululo eziqukethe u-5 kuya ku-10% zisetshenziswe njengezicelo zasendaweni ezilonda nasekuvimbeleni ukuphuma okungcolile okuvela ebusweni be-mucous (2). I-aluminium sulfate itholakala ezintweni ezisetshenziswa embonini yezemithi. Isibonelo, isetshenziswa ekulungiseleleni amaconsi ezindlebeni ze-aluminium acetate (2).
IZICELO ZOMKHANDLU WOKUDLA
I-Alum isetshenziswa ngezinjongo eziningi ekudleni esikudlayo futhi ngokuvamile ibhekwa njengephephile uma isetshenziswa ngokuvumelana nomkhuba omuhle wokukhiqiza (2). Iyancibilika emanzini futhi isetshenziswa kakhulu njenge-thickener kanye ne-emulsifier (3).
I-Alum ingasetshenziswa futhi ku:
- Hlaziya futhi ucacise amanzi eziphuzo ezibandayo kanye nobhiya
- Lawula amazinga e-pH ku-beet, utamatisi, kanye neminye imifino
- Ukuhlanzwa kwamajusi kashukela
- Lawula i-pH nombala wewayini notshwala
- Sebenzisa njenge-ejenti yokubilisa engxubeni yamakhekhe (i-baking soda)
- Qedela ushizi bese uwujiyisa (4).
