Izicelo zevolumu encane ye-caustic soda zihlanganisa imikhiqizo yokuhlanza yasendlini, ukwelashwa kwamanzi, izinto zokuhlanza amabhodlela eziphuzo, ukwenza insipho yasekhaya, phakathi kokunye.
Embonini yensipho neyokuhlanza, i-caustic soda isetshenziswa ku-saponification, inqubo yamakhemikhali eguqula amafutha emifino abe insipho.Isoda ye-Caustic isetshenziselwa ukwenza izinto ezikhipha i-anionic, ingxenye ebalulekile emikhiqizweni eminingi yokuhlanza neyokuhlanza.
Imboni kawoyela negesi isebenzisa i-caustic soda ekuhloleni, ekukhiqizeni nasekucubunguleni i-petroleum negesi yemvelo, lapho isusa khona iphunga elibi elivela ku-hydrogen sulfide (H2S) kanye ne-mercaptans.
Ekukhiqizeni i-aluminium, i-caustic soda isetshenziselwa ukuncibilikisa i-bauxite ore, impahla eluhlaza yokukhiqiza i-aluminium.
Ku-Chemical Processing Industries (CPI), i-caustic soda isetshenziswa njengezinto ezingavuthiwe noma amakhemikhali okucubungula ezinhlobonhlobo zemikhiqizo engaphansi komfula, njengamapulasitiki, amakhemisi, ama-solvents, izindwangu zokwenziwa, izinto zokunamathisela, odayi, okokunamathela, oyinki, phakathi kokunye.Ibuye isetshenziselwe ukwenza i-neutralization yemifudlana yemfucuza ene-asidi kanye nokukhuhla izingxenye ezine-asidi emagesini angekho.
Izicelo zevolumu encane ye-caustic soda zihlanganisa imikhiqizo yokuhlanza yasendlini, ukwelashwa kwamanzi, izinto zokuhlanza amabhodlela eziphuzo, ukwenza insipho yasekhaya, phakathi kokunye.
