I-sodium dichloroisocyanurate(DCCNA), i-organic compound, ifomula yi-C3Cl2N3NaO3, ekamelweni lokushisa njengamakristalu empushana emhlophe noma izinhlayiya, iphunga le-chlorine.
I-sodium dichloroisocyanurate iyisibulala-magciwane esivame ukusetshenziswa esinamandla oxidizability.Inomphumela oqinile wokubulala kuma-microorganisms ahlukahlukene we-pathogenic njengamagciwane, izinhlamvu zebhaktheriya, isikhunta nokunye.Iwuhlobo lwesibulala-magciwane olunobubanzi bokusetshenziswa okubanzi nokusebenza kahle okuphezulu.
Izakhiwo zomzimba namakhemikhali:
I-crystalline powder emhlophe, enephunga eliqinile le-chlorine, equkethe 60% ~ 64.5% i-chlorine esebenzayo.Iqinile futhi igcinwe endaweni eshisayo neswakeme.Okuqukethwe kwe-chlorine okusebenzayo kwehla ngo-1% kuphela.Incibilika kalula emanzini, ukunyibilika okungu-25%(25℃).Isixazululo sine-asidi ebuthakathaka, futhi i-pH ye-aqueous solution engu-1% ingu-5.8 ~ 6.0.I-pH ishintsha kancane njengoba ukugxila kukhula.I-Hypochlorous acid ikhiqizwa emanzini, futhi i-hydrolysis yayo engaguquki i-1 × 10-4, ephakeme kune-chloramine T. Ukuzinza kwesisombululo se-aqueous akubi, futhi ukulahlekelwa kwe-chlorine esebenzayo kuyashesha ngaphansi kwe-UV Chemicalbook.Ukuhlushwa okuphansi kungabulala ngokushesha izinhlobo ezihlukahlukene ze-bacterial propagules, isikhunta, amagciwane, igciwane le-hepatitis linemiphumela ekhethekile.Inezici zokuqukethwe okuphezulu kwe-chlorine, isenzo esinamandla se-bactericidal, inqubo elula kanye nentengo eshibhile.Ubuthi be-sodium dichloroisocyanurate buphansi, futhi umphumela we-bactericidal ungcono kunalowo we-bleaching powder ne-chloramine-T.I-Chlorine fuming agent noma i-acid fuming agent ingenziwa ngokuxuba i-metal rencicing agent noma i-acid synergist ne-potassium permanganate kanyesodium dichloroisocyanurateimpushana eyomile.Lolu hlobo lwemfucuza luzokhiqiza igesi enamandla ebulala amagciwane ngemva kokuthungela.
Izici zomkhiqizo:
(1) Ukuvala inzalo okuqinile namandla okubulala amagciwane.Okuqukethwe kwe-chlorine okusebenzayo kwe-DCCNa okumsulwa kungu-64.5%, futhi okuqukethwe kwe-chlorine okusebenzayo kwemikhiqizo yekhwalithi ephezulu kungaphezu kuka-60%, okunomphumela oqinile wokubulala amagciwane kanye nokuvalwa inzalo.Ku-20ppm, izinga lokuvala inzalo lifinyelela ku-99%.Inomphumela onamandla wokubulala kuzo zonke izinhlobo zamabhaktheriya, ulwelwe, isikhunta namagciwane.
(2) Ubuthi bayo buphansi kakhulu, umthamo obulalayo omaphakathi (LD50) uphezulu njengo-1.67g/kg (umthamo obulalayo omaphakathi we-trichloroisocyanuric acid ngu-0.72-0.78 g/kg kuphela).Ukusetshenziswa kwe-DCCNa ekubulaleni amagciwane nasekubulaleni amagciwane kokudla namanzi okuphuza kudala kuvunyiwe ekhaya naphesheya.
(3) Izinhlobonhlobo zokusetshenziswa, umkhiqizo awukwazi ukusetshenziswa kuphela embonini yokucubungula ukudla nesiphuzo kanye nokubulala amagciwane emanzini okuphuza, ukuhlanza kanye nokubulala amagciwane ezindaweni zomphakathi, ekuhlanzeni amanzi okujikeleza ezimbonini, ukukhishwa kwezindlu zangasese ezihlanzekile, ukubulala amagciwane embonini ye-aquaculture futhi esetshenziswa kabanzi.
(4) Izinga elisebenzayo lokusebenzisa i-chlorine liphezulu, futhi ukuncibilika kwe-DCCNa emanzini kuphezulu kakhulu.Ku-25℃, wonke amanzi angu-100mL angancibilikisa i-30g DCCNa.Ngisho nasesisombululo esinamanzi esinezinga lokushisa lamanzi eliphansi njengo-4°C, i-DCCNa ingakhulula ngokushesha yonke i-chlorine esebenzayo equkethe, isebenzise ngokugcwele umphumela wayo wokubulala amagciwane kanye nomphumela wokubulala amagciwane.Eminye imikhiqizo eqinile ene-chlorine (ngaphandle kwe-chloro-isocyanuric acid) inamanani aphansi kakhulu e-chlorine kune-DCCNa ngenxa yokuncibilika okuphansi noma ukukhishwa kancane kwe-chlorine equkethwe kuyo.
(5) Ukuzinza okuhle.Ngenxa yokuqina okuphezulu kwamasongo e-triazine emikhiqizweni ye-chloro-isocyanuric acid, izakhiwo ze-DCCNa zizinzile.I-DCCNa eyomile egcinwe endaweni yokugcina impahla inqunywe ukuthi ibe nokulahlekelwa okungaphansi kuka-1% we-chlorine etholakalayo ngemva konyaka ongu-1.
(6) Umkhiqizo uqinile, ungenziwa ube yimpushana emhlophe noma izinhlayiya, ukupakishwa okulula nokuhamba, kodwa futhi kulula kubasebenzisi ukukhetha nokusebenzisa.
UmkhiqizoAisicelo:
I-DCCNa iwuhlobo lwe-disinfection esebenzayo kanye nesibulala-sikhunta, enokuncibilika okuphezulu emanzini, ikhono lokubulala amagciwane okuhlala isikhathi eside kanye nobuthi obuphansi, ngakho-ke isetshenziswa kabanzi njengesibulala-magciwane samanzi okuphuza kanye nesibulala-magciwane sasendlini.I-DCCNa i-hydrolyze i-hypochlorous acid emanzini futhi ingathatha indawo ye-hypochlorous acid kwezinye izimo, ngakho ingasetshenziswa njenge-bleach.Ngaphezu kwalokho, ngenxa yokuthi i-DCCNa ingakhiqizwa ngezinga elikhulu futhi intengo iphansi, isetshenziswa kabanzi ezimbonini eziningi:
1) i-ejenti yokwelapha ye-wool anti-shrinkage;
2) Ukuhlanza imboni yezindwangu;
3) Ukuvala inzalo kanye nokubulala amagciwane embonini yezasemanzini;
4) Ukubulala amagciwane ngokukhucululwa kwendle;
5) Ukwelashwa kwamanzi okujikeleza kwezimboni;
6) Ukuhlanza nokubulala amagciwane embonini yokudla nezindawo zomphakathi.
Indlela yokulungiselela:
(1) I-Dichlorylisocyanuric acid neutralization (indlela ye-chloride) i-cyanuric acid ne-caustic soda ngokusho kwesilinganiso esingu-1: 2 se-molar ibe isixazululo esinamanzi, i-chlorinated ibe yi-dichloroisocyanuric acid, ukuhlunga kwe-slurry ukuthola ikhekhe le-dichloroisocyanuric acid filter ingahlanzwa ngokugcwele ngamanzi, isuse ikhekhe le-sodium i-chloride, i-dichloroisocyanuric acid.I-dichloroisocyanurate emanzi yaxutshwa namanzi ku-slurry, noma yafakwa kutshwala kamama be-sodium dichloroisocyanurate, futhi ukusabela kwe-neutralization kwenziwa ngokuwisa i-caustic soda ngesilinganiso se-molar esingu-1:1.Isixazululo sokusabela sipholile, sicwebezeliswe futhi sihlungwe ukuze kutholakale i-sodium dichloroisocyanurate emanzi, eyomiswa ukuze ibe yimpuphu.sodium dichloroisocyanuratenoma i-hydrate yayo.
(2) Indlela ye-sodium hypochlorite okokuqala yenziwa nge-caustic soda negesi ye-chlorine ukusabela ukukhiqiza isisombululo se-sodium hypochlorite ngokugxila okufanele.I-Chemicalbook ingahlukaniswa ngezinhlobo ezimbili zenqubo ene-concentration ephezulu nephansi ngokusho kokuhlushwa okuhlukene kwesisombululo se-sodium hypochlorite.I-sodium hypochlorite ihlangana ne-cyanuric acid ukukhiqiza i-dichloroisocyanuric acid ne-sodium hydroxide.Ukuze kulawulwe inani le-pH lokusabela, igesi ye-chlorine ingangezwa ukwenza i-sodium hydroxide negesi ye-chlorine ukukhiqiza i-sodium hypochlorite iqhubeke nokubamba iqhaza ekuphenduleni, ukuze kusetshenziswe ngokugcwele izinto zokusetshenziswa zokusabela.Kodwa ngenxa yokuthi igesi ye-chlorine ihileleke ekuphenduleni kwe-chlorination, izidingo zokulawula ku-cyanuric acid eluhlaza kanye nezimo zokusebenza zokusabela ziqinile uma kuqhathaniswa, ngaphandle kwalokho kulula ukwenzeka ingozi yokuqhuma kwe-nitrogen trichloride;Ngaphezu kwalokho, i-asidi ye-inorganic (efana ne-hydrochloric acid) ingasetshenziswa futhi ukuze inciphise indlela, engafaki igesi ye-chlorine ngokuqondile ekuphenduleni, ngakho-ke ukusebenza kulula ukulawula, kodwa ukusetshenziswa kwe-sodium hypochlorite eluhlaza akuphelele. .
Izimo zesitoreji nezokuthutha nokupakisha:
I-sodium dichloroisocyanurate ipakishwa ezikhwameni ezilukiweyo, amabhakede epulasitiki noma amabhakede ekhadibhodi: 25KG/ isikhwama, 25KG/ ibhakede, 50KG/ ibhakede.
Gcina endaweni epholile, eyomile futhi enomoya omuhle.Gcina kude nomlilo nokushisa.Ungangeni elangeni eliqondile.Iphakheji kufanele ivalwe futhi ivikelwe kumswakama.Kufanele igcinwe ngokuhlukana nezinto ezivuthayo, usawoti we-ammonium, ama-nitrides, ama-oxidants nama-alkali, futhi akufanele ihlanganiswe.Indawo yokugcina kufanele ifakwe izinto ezifanele ukuqukatha ukuvuza.
