Sodium dichloroisocyanurate(DCCNA), yog ib qho organic compound, cov mis yog C3Cl2N3NaO3, nyob rau hauv chav tsev kub li dawb hmoov crystals los yog hais, chlorine tsw.
Sodium dichloroisocyanurate yog ib hom tshuaj tua kab mob uas muaj zog oxidizability.Nws muaj zog tua cov kab mob ntau yam kab mob xws li kab mob, kab mob spores, fungi thiab lwm yam.Nws yog ib hom kab mob bactericidal nrog ntau daim ntawv thov thiab kev ua haujlwm siab.
Lub cev thiab tshuaj muaj zog:
Dawb crystalline hmoov, muaj zog chlorine tsw, muaj 60% ~ 64.5% chlorine zoo.Nws ruaj khov thiab khaws cia hauv qhov chaw kub thiab av noo.Cov ntsiab lus chlorine zoo txo qis los ntawm 1%.Yooj yim soluble hauv dej, solubility ntawm 25% (25 ℃).Cov tshuaj tsis muaj zog acidic, thiab pH ntawm 1% aqueous tov yog 5.8 ~ 6.0.Cov pH hloov me ntsis thaum lub concentration nce.Hypochlorous acid yog tsim nyob rau hauv dej, thiab nws cov hydrolysis tas li yog 1 × 10-4, uas yog siab tshaj chloramine T. Lub stability ntawm aqueous kua yog tsis zoo, thiab qhov poob ntawm zoo chlorine accelerates nyob rau hauv UV Chemicalbook.Tsawg concentration tuaj yeem tua ntau yam kab mob sai sai, cov kab mob fungi, kab mob, kab mob siab muaj peev xwm tshwj xeeb.Nws muaj cov yam ntxwv ntawm cov ntsiab lus chlorine siab, muaj zog bactericidal nkaus, txheej txheem yooj yim thiab pheej yig tus nqi.Cov tshuaj toxicity ntawm sodium dichloroisocyanurate qis dua, thiab cov kab mob bactericidal zoo dua li cov tshuaj dawb thiab chloramine-T.Chlorine fuming agent lossis acid fuming agent tuaj yeem tsim los ntawm kev sib xyaw hlau txo tus neeg saib xyuas lossis acid synergist nrog poov tshuaj permanganate thiabsodium dichloroisocyanuratehmoov qhuav.Hom fumigant no yuav tsim cov roj bactericidal muaj zog tom qab ignition.
Khoom nta:
(1) Muaj zog ua kom tsis muaj menyuam thiab muaj peev xwm tua kab mob.Cov ntsiab lus chlorine zoo ntawm cov ntshiab DCCna yog 64.5%, thiab cov ntsiab lus chlorine zoo ntawm cov khoom zoo yog ntau tshaj 60%, uas muaj zog tua kab mob thiab ua kom tsis muaj menyuam.Ntawm 20ppm, sterilization tus nqi nce mus txog 99%.Nws muaj zog tua cov nyhuv ntawm txhua yam kab mob, algae, fungi thiab kab mob.
(2) Nws cov tshuaj toxicity tsawg heev, qhov nruab nrab tus neeg tuag koob tshuaj (LD50) yog siab li 1.67g / kg (qhov nruab nrab noj tshuaj trichloroisocyanuric acid tsuas yog 0.72-0.78 g / kg).Kev siv DCCna hauv kev tua kab mob thiab tua kab mob ntawm cov zaub mov thiab dej haus tau ntev tau pom zoo nyob hauv tsev thiab txawv teb chaws.
(3) Kev siv ntau yam, cov khoom siv tsis yog tsuas yog siv rau hauv kev lag luam khoom noj thiab dej haus thiab dej haus tshuaj tua kab mob, ntxuav thiab tua kab mob ntawm pej xeem chaw, hauv kev lag luam circulating dej kho, pej xeem tshuaj tua kab mob hauv tsev, tshuaj tua kab mob hauv kev lag luam aquaculture yog kuj tau siv dav.
(4) Cov tshuaj chlorine siv tau zoo yog siab, thiab solubility ntawm DCCna hauv dej yog siab heev.Ntawm 25 ℃, txhua 100mL dej tuaj yeem yaj 30g DCNa.Txawm tias nyob rau hauv cov kua dej nrog dej kub tsawg li 4 ° C, DCCna tuaj yeem tso tawm tag nrho cov tshuaj chlorine uas nws muaj, ua kom tag nrho nws cov tshuaj tua kab mob thiab cov kab mob bactericidal.Lwm cov khoom uas muaj cov tshuaj chlorine (tshwj tsis yog chloro-isocyanuric acid) muaj cov tshuaj chlorine qis dua li DCCna vim yog solubility tsawg lossis qeeb ntawm cov tshuaj chlorine uas muaj nyob hauv lawv.
(5) Zoo stability.Vim lub siab ruaj khov ntawm triazine rings nyob rau hauv chloro-isocyanuric acid cov khoom, DCCna cov khoom yog ruaj khov.Qhuav DCNa khaws cia hauv lub tsev khaws khoom tau txiav txim siab kom muaj qhov poob qis dua 1% ntawm cov tshuaj chlorine tom qab 1 xyoos.
(6) Cov khoom yog khoom, tuaj yeem ua cov hmoov dawb los yog cov khoom, yooj yim ntim thiab thauj, tab sis kuj yooj yim rau cov neeg siv xaiv thiab siv.
KhoomAdaim ntawv thov:
DCCna yog ib hom tshuaj tua kab mob zoo thiab cov kab mob fungicide, nrog rau cov dej solubility siab, muaj peev xwm tua kab mob ntev thiab tsis muaj toxicity, yog li nws yog dav siv los ua tshuaj tua kab mob hauv tsev thiab tshuaj tua kab mob hauv tsev.DCCna hydrolyzes hypochlorous acid hauv dej thiab tuaj yeem hloov cov kua qaub hypochlorous hauv qee kis, yog li nws tuaj yeem siv los ua tshuaj dawb.Ntxiv mus, vim DCCNa tuaj yeem ua rau ntawm qhov loj thiab tus nqi qis, nws tau siv dav hauv ntau qhov kev lag luam:
1) wool anti-shrinkage kho tus neeg saib xyuas;
2) Bleaching rau kev lag luam textile;
3) Sterilization thiab tshuaj tua kab mob ntawm kev lag luam aquaculture;
4) Kev tua kab mob hauv pej xeem;
5) Industrial circulating dej kho;
6) Kev ntxuav thiab tshuaj tua kab mob ntawm kev lag luam zaub mov thiab cov chaw pej xeem.
Txoj kev npaj:
(1) Dichlorylisocyanuric acid neutralization (chloride method) cyanuric acid thiab caustic soda raws li 1: 2 molar ratio rau hauv cov kua dej, chlorinated rau dichloroisocyanuric acid, slurry pom kom tau dichloroisocyanuric acid lim ncuav mog qab zib tuaj yeem ntxuav tag nrho nrog dej, tshem tawm cov ncuav mog qab zib sodium chloride, dichloroisocyanuric acid.Cov ntub dej dichloroisocyanurate tau tov nrog dej hauv slurry, lossis muab tso rau hauv niam cawv ntawm sodium dichloroisocyanurate, thiab cov tshuaj tiv thaiv neutralization yog nqa tawm los ntawm kev xau caustic soda ntawm molar ratio ntawm 1: 1.Cov tshuaj tiv thaiv yog txias, crystallized thiab lim kom tau ntub sodium dichloroisocyanurate, uas yog ces qhuav kom tau hmoov.sodium dichloroisocyanuratelos yog nws hydrate.
(2) Sodium hypochlorite txoj kev yog thawj zaug ua los ntawm caustic soda thiab chlorine gas cov tshuaj tiv thaiv los tsim sodium hypochlorite tov nrog qhov tsim nyog concentration.Chemicalbook tuaj yeem muab faib ua ob hom txheej txheem nrog siab thiab qis concentration raws li qhov sib txawv ntawm sodium hypochlorite tov.Sodium hypochlorite reacts nrog cyanuric acid los tsim dichloroisocyanuric acid thiab sodium hydroxide.Txhawm rau tswj hwm tus nqi pH ntawm cov tshuaj tiv thaiv, cov tshuaj chlorine tuaj yeem ntxiv los ua sodium hydroxide thiab chlorine gas los tsim sodium hypochlorite txuas ntxiv mus koom nrog cov tshuaj tiv thaiv, thiaj li ua kom tag nrho cov khoom siv tshuaj tiv thaiv.Tab sis vim tias cov roj chlorine koom nrog cov tshuaj tiv thaiv chlorination, kev tswj cov kev cai ntawm cov khoom siv raw cyanuric acid thiab cov kev ua haujlwm ntawm cov tshuaj tiv thaiv yog nruj, txwv tsis pub nws yog ib qho yooj yim uas yuav tshwm sim nitrogen trichloride tawg sib tsoo;Tsis tas li ntawd, inorganic acid (xws li hydrochloric acid) kuj tuaj yeem siv los ua kom tsis zoo ntawm txoj kev, uas tsis cuam tshuam cov roj chlorine ncaj qha rau hauv cov tshuaj tiv thaiv, yog li kev ua haujlwm yooj yim los tswj, tab sis kev siv cov khoom siv raw sodium hypochlorite tsis tiav. .
Cia thiab kev thauj mus los & Ntim:
Sodium dichloroisocyanurate yog ntim rau hauv hnab woven, thoob yas los yog thawv thawv: 25KG / hnab, 25KG / thoob, 50KG / thoob.
Khaws rau hauv qhov chaw txias, qhuav thiab zoo-ventilated warehouse.Khaws kom deb ntawm hluav taws thiab cua sov.Khaws tawm ntawm tshav ntuj ncaj qha.Lub pob yuav tsum raug kaw thiab tiv thaiv los ntawm ya raws.Nws yuav tsum tau muab cais los ntawm cov khoom siv hluav taws xob, ammonium ntsev, nitrides, oxidants thiab alkalis, thiab yuav tsum tsis txhob sib xyaw.Qhov chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog kom muaj cov xau.
