Jawaabta oo kooban waa haa. Cyanuric acid ayaa hoos u dhigi doonta pH ee biyaha barkada.
Cyanuric acid waa asiidh dhab ah iyo pH ee 0.1% xalalka cyanuric acid waa 4.5. Uma eka inay acidic badan tahay halka pH ee 0.1% sodium bisulfate xalku yahay 2.2 iyo pH ee 0.1% hydrochloric acid waa 1.6. Laakiin fadlan ogow in pH ee barkadaha dabaasha ay u dhexeeyaan 7.2 iyo 7.8 pKa ugu horeysa ee cyanuric acid waa 6.88. Tani waxay ka dhigan tahay in molecules cyanuric acid intooda badan ee barkada dabaasha ay sii deyn karaan hydrogen ion iyo awoodda cyanuric acid inay hoos u dhigto pH waxay aad ugu dhowdahay tan sodium bisulfate taas oo inta badan loo isticmaalo sida pH yareeyaha.
Tusaale ahaan:
Waxaa jira barkad dabaasha oo dibadda ah. pH bilowga ah ee biyaha barkada waa 7.50, wadarta alkalinity waa 120 ppm halka heerka cyanuric acid uu yahay 10 ppm. Wax walba si habsami ah ayey u shaqeeyaan marka laga reebo heerka aashitada cyanuric eber. Aynu ku darno 20 ppm oo cyanuric acid qalalan. Cyanuric acid si tartiib ah ayey u milmaan, badanaa waxay qaadataa 2 ilaa 3 maalmood. Marka aashitada cyanuric ay si buuxda u milanto pH ee biyaha barkada waxay noqon doontaa 7.12 taas oo ka hooseysa qiyaasta hoose ee pH (7.20). 12 ppm sodium carbonate ama 5 ppm ee sodium hydroxide ayaa loo baahan yahay si loogu daro si loo hagaajiyo dhibaatada pH.
Monosodium cyanurate dareere ama slurry ayaa laga heli karaa dukaamada barkadaha qaarkood. 1 ppm monosodium cyanurate waxay ku kordhin doontaa heerka aashitada cyanuric 0.85 ppm. Monosodium cyanurate si dhakhso ah ayey ugu milmi kartaa biyaha, markaa way ku habboon tahay in la isticmaalo oo waxay si dhakhso ah u kordhin kartaa heerarka aashitada cyanuric ee barkadda dabaasha. Si ka duwan aashitada cyanuric, dareeraha monosodium cyanurate waa alkaline (pH ee 35% slurry waa inta u dhaxaysa 8.0 ilaa 8.5) wax yarna wuxuu kordhiyaa pH ee biyaha barkada. Barkadda sare ku xusan, pH ee biyaha barkada waxay kordhin doontaa 7.68 ka dib marka lagu daro 23.5 ppm ee monosodium cyanate saafi ah.
Ha iloobin in cyanuric acid iyo monosodium cyanurate ee ku jira barkada biyaha ay sidoo kale u dhaqmaan sida kaydiyayaal. Taasi waa, mar kasta oo uu sareeyo heerka aashitada cyanuric, waa yaraanta ay u badan tahay in pH-gu uu dhaqaaqi doono. Markaa fadlan xasuuso inaad dib u tijaabiso wadarta alkalinity marka pH ee biyaha barkada loo baahan yahay si loo hagaajiyo.
Sidoo kale ogow in cyanuric acid uu ka awood badan yahay sodium carbonate, markaa hagaajinta pH waxay u baahan tahay in lagu daro asiidh ama alkali ka badan iyada oo aan lahayn cyanuric acid.
Barkadda dabaasha oo pH-ga bilowga ah ay tahay 7.2 pH-ga la doonayona waa 7.5, wadarta guud ee alkalinity waa 120 ppm halka heerka cyanuric acid uu yahay 0, 7 ppm ee sodium carbonate ayaa loo baahan yahay si loo buuxiyo pH la doonayo. Hayso pH-ga bilowga ah, pH-ga la rabo iyo wadarta alkalinity waa 120 ppm aan isbeddelin laakiin u beddel heerka cyanuric acid ilaa 50 ppm, 10 ppm ee sodium carbonate ayaa hadda loo baahan yahay.
Marka pH u baahan tahay in hoos loo dhigo, cyanuric acid saamayn yar bay leedahay. Barkadda dabaasha oo pH-ga bilowga ah ay tahay 7.8 pH-da la doonayona ay tahay 7.5, wadarta guud ee alkalinity waa 120 ppm iyo heerka cyanuric acid waa 0, 6.8 ppm sodium bisulfate ayaa loo baahan yahay si loo buuxiyo pH la doonayo. Hayso pH bilawga ah, pH-ga la rabo iyo wadarta alkalinity waa 120 ppm aan isbeddelin laakiin u beddel heerka cyanuric acid ilaa 50 ppm, 7.2 ppm ee sodium bisulfate ayaa loo baahan yahay - kaliya 6% kordhinta qiyaasta sodium bisulfate.
Cyanuric acid sidoo kale waxay leedahay faa'iido in aysan samayn doonin miisaan leh calcium ama biraha kale.
