Ezimbonini zokunyathelisa nezokudaya, ngenxa yemithombo yamanzi ehlukene, izinga lamanzi nalo lihlukile. Ngokuvamile, izimboni eziningi zokunyathelisa nezokudaya zisebenzisa amanzi angaphezulu emvelo, amanzi angaphansi komhlaba noma amanzi ampompi.
Amanzi emvelo angalashwa aqukethe izinto ezihlukahlukene zamakhemikhali, njenge-calcium, i-magnesium, insimbi, i-sodium, i-carbonate, i-sulfate ne-chloride, ezoba nomthelela omkhuluizindwanguukudaya.
Izinga lokuphrinta kwendwangu kanye nokudaya linezidingo ezithile ngekhwalithi yamanzi. Amanzi aqinile azothinta umphumela wokugcoba futhi aholele ekudayeni okungalingani, ukuzwa kwesandla esibi kanye nokuphuzi kwezindwangu. Kodwa ukwengeza isithambisa samanzi kuzokwandisa umthamo we-caustic soda nezinye izithasiselo.
I-calcium ne-magnesium, engancibiliki emanzini, izofaka endwangu futhi yakhe ingxube ye-alkali ukuze inamathisele kumishini evimbela ukukhiqizwa. Uma usawoti we-iron ne-manganese emanzini udlula izinga, kulula ukukhiqiza izindawo zokugqwala futhi kubangele ukubola kwe-cotton fiber ngesikhathi sokubilisa nokukhuhlwa. Uma usebenzisa i-oxidizing ejentini yokwenza i-blekning, i-iron ne-manganese usawoti kuzophinde kubangele ukubola kwe-ejenti yokumhlophe.
Niniukudayangamadayi asebenzayo, ithonya lobulukhuni bamanzi alibalulekile. Kodwa lapho udaywa inayiloni ngodayi be-asidi, ithonya lobulukhuni bamanzi alibalulekile. Amanzi aqinile kakhulu ngeke nje enze umbala nokucwebezela kwendwangu kumpofu, kodwa i-CI emanzini nayo inethonya elikhulu ekudayeni.
Izinto eziqinile ezimisiwe emanzini aqinile zizoba nomthelela ekubeni mhlophe kokumhlophe. Uma udaya ushizi, kulula ukunciphisa ukugqama kwezingqimba zangaphakathi nezingaphandle zentambo kashizi. Inani eliphakeme le-pH yamanzi lizothinta impahla yokulinganisa yezindwangu ezinombala okhanyayo. Lokhu kungenxa yokuthi ngaphansi kwesimo se-alkali, odayi abengeziwe bazolungiswa, okuholela ekulinganisweni okubi kanye namabala okudaya.
Uma inani le-pH lamanzi liphezulu kakhulu, lizokwenza odayi babe yi-hydrolyze enqubweni yensipho, okuzodala ukukhiqizwa kabusha okubi. Futhi ngisho nasenqubweni yokuthambisa, kuzobangela ukuthi indwangu pH idlule izinga.
Ama-iron engeziwe azodala amabala ombala, izindawo zokudaya kanye nomthunzi wombala ofiphele. I-manganese ion eyeqile iyisizathu esiyinhloko sokuphuzi kwezindwangu ezimhlophe.
Amanzi aqinile azothonya ukukhanya kombala futhi azoholela ekungcolisweni kwezishintshi zokushisa. Isebenzisa amandla aphezulu. Ngaphezu kwalokho, i-calcium ne-magnesium ions kanye ne-sodium carbonate kuzokhiqiza inzika engancibiliki, okuzodala amabala e-alkali.
