Impendulo emfushane inguyebo. I-Cyanuric acid izokwehlisa i-pH yamanzi echibini.
I-cyanuric acidiyi-asidi yangempela kanti i-pH yesisombululo se-cyanuric acid esingu-0.1% ingu-4.5. Akubonakali sengathi ine-asidi kakhulu kuyilapho i-pH yesisombululo se-sodium bisulfate esingu-0.1% ingu-2.2 kanti i-pH ye-hydrochloric acid engu-0.1% ingu-1.6. Kodwa sicela uqaphele ukuthi i-pH yamachibi okubhukuda iphakathi kuka-7.2 no-7.8 kanti i-pKa yokuqala ye-cyanuric acid ingu-6.88. Lokhu kusho ukuthi ama-molecule amaningi e-cyanuric acid echibini lokubhukuda angakhipha i-hydrogen ion futhi ikhono le-cyanuric acid lokwehlisa i-pH lisondele kakhulu kwele-sodium bisulfate evame ukusetshenziswa njengesinciphisi se-pH.
Ngokwesibonelo:
Kukhona ichibi lokubhukuda elingaphandle. I-pH yokuqala yamanzi echibini ingu-7.50, i-alkalinity iyonke ingu-120 ppm kanti izinga le-cyanuric acid lingu-10 ppm. Konke kusesimweni esisebenzayo ngaphandle kwezinga le-cyanuric acid elingu-zero. Ake sengeze u-20 ppm we-cyanuric acid eyomile. I-Cyanuric acid iyancibilika kancane kancane, ngokuvamile ithatha izinsuku ezi-2 kuya kwezi-3. Uma i-cyanuric acid incibilika ngokuphelele, i-pH yamanzi echibini izoba ngu-7.12 okungaphansi komkhawulo ophansi onconywayo we-pH (7.20). Kudingeka i-12 ppm ye-sodium carbonate noma i-5 ppm ye-sodium hydroxide ukuze kulungiswe inkinga ye-pH.
Uketshezi lwe-monosodium cyanurate noma i-slurry luyatholakala kwezinye izitolo zamachibi. I-monosodium cyanurate engu-1 ppm izokwandisa izinga le-cyanuric acid ngo-0.85 ppm. I-Monosodium cyanurate incibilika ngokushesha emanzini, ngakho-ke kulula ukuyisebenzisa futhi ingakhuphula ngokushesha amazinga e-cyanuric acid echibini lokubhukuda. Ngokuphambene ne-cyanuric acid, uketshezi lwe-monosodium cyanurate luyi-alkaline (i-pH engu-35% slurry iphakathi kuka-8.0 kuya ku-8.5) futhi ikhuphula kancane i-pH yamanzi echibini. Echibini okukhulunywe ngalo ngenhla, i-pH yamanzi echibini izokhuphuka ibe ngu-7.68 ngemuva kokwengeza u-23.5 ppm we-monosodium cyanurate emsulwa.
Ungakhohlwa ukuthi i-cyanuric acid kanye ne-monosodium cyanurate emanzini echibi nakho kusebenza njengezinto zokuvimba. Okusho ukuthi, uma izinga le-cyanuric acid liphezulu, mancane amathuba okuthi i-pH izokhukhuleka. Ngakho-ke sicela ukhumbule ukuhlola kabusha i-alkalinity iyonke uma kudingeka i-pH yamanzi echibi ukuze kulungiswe.
Qaphela futhi ukuthi i-cyanuric acid iyi-buffer enamandla kune-sodium carbonate, ngakho-ke ukulungiswa kwe-pH kudinga ukwengeza i-asidi noma i-alkali eningi kunaleyo engenayo i-cyanuric acid.
Echibini lokubhukuda lapho i-pH yokuqala ingu-7.2 kanye ne-pH efiselekayo ingu-7.5, i-alkalinity iyonke ingu-120 ppm kanti izinga le-cyanuric acid lingu-0, 7 ppm le-sodium carbonate liyadingeka ukuze kuhlangatshezwane ne-pH efiselekayo. Gcina i-pH yokuqala, i-pH efiselekayo kanye ne-alkalinity iyonke ingu-120 ppm ingashintshi kodwa shintsha izinga le-cyanuric acid libe ngu-50 ppm, i-10 ppm ye-sodium carbonate iyadingeka manje.
Uma i-pH idinga ukwehla, i-cyanuric acid ayiba nomthelela omkhulu. Echibini lokubhukuda lapho i-pH yokuqala ingu-7.8 kanti i-pH efiselekayo ingu-7.5, i-alkalinity iyonke ingu-120 ppm kanti izinga le-cyanuric acid lingu-0, 6.8 ppm le-sodium bisulfate liyadingeka ukuze kuhlangatshezwane ne-pH efiselekayo. Gcina i-pH yokuqala, i-pH efiselekayo kanye ne-alkalinity iyonke ingu-120 ppm ingashintshi kodwa shintsha izinga le-cyanuric acid libe ngu-50 ppm, i-7.2 ppm ye-sodium bisulfate iyadingeka - ukwanda okungu-6% kuphela komthamo we-sodium bisulfate.
I-cyanuric acid inenzuzo yokuthi ngeke yakheke njengesilinganiso nge-calcium noma ezinye izinsimbi.
