Ngaba i-cyanuric acid iyanyusa okanye yehlisa i-pH?

Impendulo emfutshane nguewe. Iasidi yeCyanuric iya kuthoba i-pH yamanzi echibini.

Iasidi yeCyanuricyi-asidi yokwenyani kunye ne-pH ye-0.1% yesisombululo se-cyanuric acid yi-4.5. Ayibonakali i-acidic kakhulu ngelixa i-pH ye-0.1% yesisombululo se-sodium bisulfate yi-2.2 kunye ne-pH ye-0.1% ye-hydrochloric acid yi-1.6. Kodwa nceda uqaphele ukuba i-pH yamachibi okudada iphakathi kwe-7.2 kunye ne-7.8 kunye ne-pKa yokuqala ye-cyanuric acid yi-6.88. Oku kuthetha ukuba iialekyuli ezininzi ze-cyanuric acid kwidama lokuqubha zinokukhupha i-ion ye-hydrogen kwaye isakhono se-cyanuric acid ukuthoba i-pH sisondele kakhulu kuleyo ye-sodium bisulfate edla ngokusetyenziswa njenge-pH reducer.

Umzekelo:

Kukho idama lokuqubha langaphandle. I-pH yokuqala yamanzi e-pool yi-7.50, i-alkalinity iyonke yi-120 ppm ngelixa inqanaba le-cyanuric acid li-10 ppm. Yonke into ikwimeko esebenza ngokusesikweni ngaphandle kwenqanaba le-zero cyanuric acid. Makhe songeze i-20 ppm ye-cyanuric acid eyomileyo. I-Cyanuric acid iyanyibilika kancinane, idla ngokuthatha iintsuku ezi-2 ukuya kwezi-3. Xa i-cyanuric acid inyibilika ngokupheleleyo i-pH yamanzi echibini iya kuba yi-7.12 engaphantsi kunomlinganiselo osezantsi ocetyiswayo we-pH (7.20). I-12 ppm ye-sodium carbonate okanye i-5 ppm ye-sodium hydroxide iyadingeka ukongeza ukulungisa ingxaki ye-pH.

Ulwelo lweMonosodium cyanrate okanye uludaka luyafumaneka kwezinye iivenkile zamadama. I-1 ppm i-monosodium cyanrate iya kwandisa inqanaba le-cyanuric acid nge-0.85 ppm. I-Monosodium cyanrate iyanyibilika ngokukhawuleza emanzini, ngoko kulula ukuyisebenzisa kwaye inokunyusa ngokukhawuleza amanqanaba e-cyanuric acid kwidama lokuqubha. Ngokuchaseneyo ne-cyanuric acid, ulwelo lwe-monosodium cyanurate lunealkaline (i-pH ye-35% yodaka iphakathi kwe-8.0 ukuya kwi-8.5) kwaye yonyusa kancinane i-pH yamanzi echibini. Kweli dama likhankanywe ngasentla, i-pH yamanzi echibini inganyuka iye kwi-7.68 emva kokongeza i-23.5 ppm ye-monosodium cynurate ecocekileyo.

Ungalibali ukuba i-cyanuric acid kunye ne-monosodium cyanrate emanzini echibi zisebenza njengezithinteli. Oko kukuthi, inqanaba le-cyanuric acid liphezulu, kuya kuba lula ukuba i-pH ikhukuliseke. Ke nceda ukhumbule ukuvavanya kwakhona i-alkalinity iyonke xa i-pH yamanzi echibini ifuneka ukulungelelanisa.

Kwakhona qaphela ukuba i-cyanuric acid sisisithinteli esinamandla kunesodium carbonate, ngoko ke ukulungiswa kwe-pH kufuna ukongeza i-asidi engaphezulu okanye i-alkali kunokuba ingenayo i-cyanuric acid.

Kwidama lokuqubha apho ipH yokuqala iyi-7.2 kunye ne-pH efunwayo yi-7.5, i-alkalinity iyonke yi-120 ppm ngelixa inqanaba le-cyanuric acid ngu-0, 7 ppm we-sodium carbonate efunekayo ukuhlangabezana ne-pH efunekayo. Gcina i-pH yokuqala, i-pH efunwayo kunye ne-alkalinity iyonke yi-120 ppm ingatshintshi kodwa utshintshe inqanaba le-cyanuric acid ukuya kwi-50 ppm, i-10 ppm ye-sodium carbonate iyadingeka ngoku.

Xa i-pH idinga ukuthotywa, i-cyanuric acid inempembelelo encinci. Kwiqula lokuqubha apho ipH yokuqala iyi-7.8 kunye ne-pH efunekayo yi-7.5, i-alkalinity iyonke yi-120 ppm kunye nenqanaba le-cyanuric acid ngu-0, 6.8 ppm we-sodium bisulfate efunekayo ukuhlangabezana ne-pH efunekayo. Gcina i-pH yokuqala, i-pH efunwayo kunye ne-alkalinity iyonke yi-120 ppm engatshintshiyo kodwa utshintshe izinga le-cyanuric acid ukuya kwi-50 ppm, i-7.2 ppm ye-sodium bisulfate iyadingeka - kuphela i-6% yokwanda kwe-dosage ye-sodium bisulfate.

I-asidi ye-Cyanuric nayo inenzuzo yokuba ayiyi kwenza isikali kunye ne-calcium okanye ezinye isinyithi.
