Sodium dichloroisocyanurate(DCCNa) yog ib qho organic compound nrog cov mis molecular ntawm c3cl2n3nao3. Nws yog dawb hmoov siv lead ua los yog particle nyob rau hauv chav tsev kub thiab muaj chlorine tsw. Soluble nyob rau hauv dej, insoluble nyob rau hauv organic solvents.
Sodium dichloroisocyanurate muaj ntau yam ntxwv thiab siv dav hauv lub neej. Thawj cov khoom yog tus cwj pwm los ntawm kev ua kom tsis muaj zog thiab muaj peev xwm tua kab mob. Raws li peb txhua tus paub, chlorine muaj cov tshuaj tua kab mob zoo thiab tiv thaiv - tus kab mob muaj peev xwm. Cov cuab yeej ntawm cov tshuaj chlorine no yog siv rau hauv cov khoom no kom loj thiab siv hauv lub neej. Cov txiaj ntsig ntawm kev soj ntsuam tau pom tias cov ntsiab lus chlorine zoo ntawm DCCna ntawm cov khoom ntshiab yog 64.5 feem pua, thiab cov ntsiab lus chlorine zoo ntawm dichloroisocyanuric acid ntawm siab - cov khoom zoo yog ntau dua 60 feem pua. Raws li kev soj ntsuam cov ntaub ntawv, nws tau pom tias qhov siab dua cov ntsiab lus chlorine hauv cov khoom, lub zog muaj peev xwm tua kab mob ntau dua (peb tuaj yeem muab kev hloov kho ntawm cov ntsiab lus sib txawv thaum tsim cov khoom). Yog li ntawd, piv nrog cov khoom ntshiab, High- cov khoom zoo muaj cov tshuaj tua kab mob thiab ua kom tsis muaj menyuam. Ntawm 20ppm, tus nqi kom tsis muaj menyuam nce mus txog 99 feem pua. Tau kawg, lub peev xwm tshuaj tua kab mob no tsis yog rau qee yam kab mob xwb, tab sis kuj muaj kev tua neeg muaj zog rau txhua yam kab mob, algae, fungi, thiab kab mob.
Qhov thib ob feature yog nws cov toxicity tsawg. Ntau tus neeg paub tias cov tshuaj toxicity thiab teeb meem coj los ntawm cov khoom siv tshuaj lom neeg muaj zog kuj tseem loj heev, yog li peb lub chaw kuaj mob tshwj xeeb ntsuas nws cov ntsiab lus toxicity ntawm nws. Qhov tshwm sim yog tias cov tshuaj toxicity tsawg heev, thiab LD50 siab li 1.67g / kg (LD50 ntawm trichloroisocyanuric acid tsuas yog 0.72 0.78g / kg). Cov ntsiab lus no ua pov thawj tias toxicity yog heev los yog txawm negligible. Tuam Tshoj muaj cov pej xeem coob thiab muaj kev xav tau ntau dua rau cov khoom siv tshuaj tua kab mob. Yog li ntawd, kev tshawb fawb ntawm cov khoom no tau pib ntxov. Tom qab ntau qhov kev sim thiab cov ntaub ntawv pov thawj muaj kev lom, DCCna tau pom zoo nyob hauv tsev thiab txawv teb chaws los siv rau hauv kev tua kab mob thiab tshuaj tua kab mob ntawm cov zaub mov thiab dej haus.
Cov txheej txheem hluavtaws ntawm DCCna yog: txoj kev no tuaj yeem muab faib ua cov txheej txheem qis sodium hypochlorite thiab siab concentration sodium hypochlorite txoj kev raws li qhov concentration ntawm sodium hypochlorite tov siv. Tsawg concentration sodium hypochlorite txoj kev: ua ntej, chlorine yog nkag mus rau hauv sodium hydroxide tov los tsim sodium hypochlorite tov nrog zoo chlorine pawg ntawm 10 feem pua 11 feem pua, ces cyanuric acid muab tso rau hauv sodium hypochlorite tov rau chlorination cov tshuaj tiv thaiv los tsim DCNa, thiab thaum kawg ntub. Cov khoom tau txais los ntawm kev ua kom txias, crystallization thiab pom, Nyob rau hauv cov tshuaj tiv thaiv ntawm cyanuric acid nrog sodium hypochlorite tov, chlorine tuaj yeem ntxiv los txhim kho cov ntsiab lus chlorine zoo ntawm cov khoom thiab inhibit qhov tsim ntawm nitrogen trichloride. Sulfuric acid thiab hydrochloric acid kuj tseem siv tau rau kev ua haujlwm nruab nrab kom txo qis pH ntawm niam cawv. Qhov kom zoo dua ntawm txoj kev qis sodium hypochlorite yog kev ua haujlwm yooj yim, tab sis kev siv tus nqi ntawm cov khoom siv raw sodium hypochlorite tsawg. Ib tug loj tus naj npawb ntawm cov ntsev inorganic yuav raug tsim nyob rau hauv chlorination seem ntawm txoj kev no, uas yuav tsum tau ntxuav nrog sodium dichloroisocyanurate saturated aqueous tov ntau zaus, yog li cov txheej txheem ntau lawm nyuaj, thiab cov ntsiab lus chlorine zoo ntawm cov khoom dichloroisocyanurate yog tsawg. Txoj kev no tsuas yog tsim rau Chlor alkali nroj tsuag uas muaj ntau ntawm los ntawm - khoom sodium hypochlorite. Thawj kauj ruam ntawm cov txheej txheem siab sodium hypochlorite yog los tsim cov sodium hypochlorite nrog cov ntsiab lus chlorine zoo ntau dua 20 feem pua (feem ntau 23 feem pua 25 feem pua), thiab tom qab ntawd chlorinate nrog cyanuric acid los tsim DCNa. Qhov zoo chlorine pawg feem ntawm cov khoom ntawm txoj kev no feem ntau nyob ntawm qhov concentration ntawm sodium hypochlorite tov. Cov khoom sib xyaw ua ke nrog siab concentration sodium hypochlorite muaj cov ntsiab lus chlorine zoo. Trichloroisocyanuric acid tuaj yeem sib koom ua ke- tsim nrog niam cawv uas tsim tawm los txhim kho kev siv cov khoom siv raw.
