IzithuthiIyona into ebalulekile yemithi yezulu, eyaziwa nge-potassium aluminum sulfate. Inamandla okubulala amabakteriya futhi ukubulala izinto ezimbi, kanye nokwenza ukusebenza okuphambene ekubulaleni izimanga zomzimba. Inkohlakalo yomzimba, okwaziwa nangokuthi inkohlakalo yezinqa, iyakhiwa ngokwenza kweswekela okhulelwe ngamakhanda okhulelwe emathunjini emathunjini kanye nabakhilomitha ekuphathweni kwesikhumba. Kukhona izithuthi eziningi zebhakteriya ezikhona esikhumba somuntu, kusukela kubhakteriya ethiwa propionic acid bacteria. Leli bhakteriya liyakhulula ifati kanye nesiprotein eswekelayo ukuze lihlanganise indlela ethiwa propionic acid, okuyisipho sokukhuleka kwesweswekela.
I-Alum inamandla amabili okwenza ukulungiswa kweswekile: ukwenza kube ngcono ukusebenza kweswekile nokubulala.
Kusuka, i-alum inamandla yokubamba kanye nokushitsha izithutha zeswele. Ukushitsha okuningi kweswele kuyisikhathi esikhulu sokuthi kube yisigqoko esikhathini somzimba. I-aluminum ions ekupheleni kwe-alum ikwakha ukushitsha. Futhi, i-potassium ions ekupheleni kwe-alum ikwakha ukubamba izintambo zesikhumba kanye nokushitsha. Ngakho, ukushitsha okuphela kuyokushitsha isigqoko esikhathini somzimba.
Kwesinye isikhathi, i-alum inamandla okubulala amabakteriya futhi ingasebenzisi ukuthuthukisa kwamabakteriya esikhumba. Ukwenza kwamabakteriya futhi ukubonakalisa kweswidi kanye ne-proteini esweleka kwezwekazi zingaba izinkomba ezikhulu ezinhlobo zokwenza ukufudumala kwesikhumba. Amasulfethi ayi-ions e-alum angasebenzisi ukubamba kwezwekazi ezindaweni zezinto ezibulalayo zasebakteriya futhi ziziveza istructure yebakteriya. Ngaphezu kwalokho, amayoni e-alum angasebenzisi ukubamba kwezilipidi ezindaweni zezinto ezibulalayo zasebakteriya futhi ziziveza istructure yomembrane yebakteriya. Lolu hlobo lwemisebenzi lusebenzisa ukuthi amabakteriya asingasebenzisi ukwenza nokufudumala, ngakho kungenzeka ukufudumala kwesikhumba.
Kwakudingeka ukuthi i-alum ikwazi ukulawula i-pH value yomzimba. I-pH value yomzimba yomuntu ekhanda kwenza ukuthi i-bacteria zizale. Ngokwesibonelo, i-data, i-alum ikwazi ukulawula i-acidity yomzimba ekhanda futhi ikwenze i-H value yakhe ibe ngokwanele. Ngakho-ke kungenzeka ukuthi i-bacteria zizale ekhanda eline okwanele, ngakho-ke i-ubuhle bokukhala kuyoba okuncane.
Kwesokudla, isilawuli somkhuhlane wemithi yemvelo kusuka kubonisa ukuzibophezela kweswekile, ukubulala nokubulala, futhi ukulawula i-pH yomzimba. I-aluminum ions ne-potassium ions kwi-alum zingase zibophezele ukuzibophezela kweswekile, zingase zibulale izimpawu zomzimba, zingase zilawule i-odor yomzimba. I-sulfate ions ne-aluminum ions kwi-alum zingase zibulale amabakteriya ezindaweni zomzimba futhi zingase zibize i-odor yomzimba. I-alum nayo ingase iyilawule i-pH yomzimba, ikwenza kube kungenzeka amabakteriya ukuthuthukisa, ekwazisa ukwenza kube kungenzeka ukuthuthukisa kweswekile.
