I-SODIUM DICHLOROISOCYANURATE

Izakhiwo zomzimba nezamakhemikhali:

Impuphu emhlophe ekristalu, enephunga elinamandla le-chlorine, equkethe i-chlorine esebenza kahle engu-60% ~ 64.5%. Izinzile futhi igcinwe endaweni eshisayo nenomswakama. Okuqukethwe kwe-chlorine esebenzayo kwehla ngo-1% kuphela. Incibilika kalula emanzini, ukuncibilika okungu-25% (25℃). Isixazululo sinobuthi obuncane, kanti i-pH yesisombululo samanzi esingu-1% ingu-5.8 ~ 6.0. I-pH ayishintshi kangako njengoba ukugcwala kukhuphuka. I-Hypochlorous acid ikhiqizwa emanzini, futhi i-hydrolysis yayo i-constant ingu-1×10-4, okuphakeme kune-chloramine T. Ukuqina kwesisombululo samanzi kubi, futhi ukulahleka kwe-chlorine esebenzayo kuyashesha ngaphansi kwe-UV Chemicalbook. Ukugcwala okuphansi kungabulala ngokushesha izinhlobo ezahlukene 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 kunowe-bleaching powder kanye ne-chloramine-T. I-chlorine fuming agent noma i-acid fuming agent ingenziwa ngokuxuba i-metal reducing agent noma i-acid synergist ne-potassium permanganate kanyei-sodium dichloroisocyanurateimpuphu eyomile. Lolu hlobo lwesifutho luzokhiqiza igesi enamandla ebulala amagciwane ngemva kokusha.

Izici zomkhiqizo:

(1) Amandla okubulala amagciwane aqinile kanye nokubulala amagciwane. Okuqukethwe kwe-chlorine okusebenzayo kwe-DCCNa emsulwa kungu-64.5%, kanti okuqukethwe kwe-chlorine okusebenzayo kwemikhiqizo esezingeni eliphezulu kungaphezu kuka-60%, okunomphumela wokubulala amagciwane oqinile kanye nokubulala amagciwane. Ku-20ppm, izinga lokubulala amagciwane lifinyelela ku-99%. Kunomphumela wokubulala oqinile kuzo zonke izinhlobo zamagciwane, ulwelwe, isikhunta kanye namagciwane.

(2) Ubuthi bayo buphansi kakhulu, umthamo obulalayo ophakathi nendawo (LD50) ufinyelela ku-1.67g/kg (umthamo obulalayo ophakathi nendawo we-trichloroisocyanuric acid u-0.72-0.78 g/kg kuphela). Ukusetshenziswa kwe-DCCNa ekubulaleni nasekubulaleni ukudla namanzi okuphuza sekuyisikhathi eside kuvunyiwe ekhaya nakwamanye amazwe.

(3) Njengoba inezinhlobo eziningi zezicelo, umkhiqizo awukwazi ukusetshenziswa kuphela embonini yokucubungula ukudla neziphuzo kanye nokuhlanza amanzi okuphuza, ukuhlanza nokuhlanza izindawo zomphakathi, ekuhlanzweni kwamanzi ajikelezayo ezimbonini, ekuhlanzweni kwezindlu zangasese zomphakathi, ukuhlanza amagciwane embonini yezolimo zasemanzini nakho kusetshenziswa kabanzi.

(4) Izinga lokusetshenziswa kwe-chlorine eliphumelelayo liphezulu, futhi ukuncibilika kwe-DCCNa emanzini kuphezulu kakhulu. Ku-25℃, wonke amanzi angu-100mL angancibilikisa i-DCCNa engama-30g. Ngisho nasesisombululo samanzi esinokushisa kwamanzi okuphansi njengo-4°C, i-DCCNa ingakhipha ngokushesha yonke i-chlorine ephumelelayo equkethe, isebenzise ngokugcwele ukubulala amagciwane kwayo kanye nomphumela wokubulala amagciwane. Eminye imikhiqizo eqinile equkethe i-chlorine (ngaphandle kwe-chloro-isocyanuric acid) inenani eliphansi kakhulu le-chlorine kune-DCCNa ngenxa yokuncibilika okuphansi noma ukukhishwa kancane kwe-chlorine equkethwe kuyo.

(5) Ukuqina okuhle. Ngenxa yokuqina okuphezulu kwamasongo e-triazine emikhiqizweni ye-chloro-isocyanuric acid, izakhiwo ze-DCCNa zizinzile. I-DCCNa eyomile egcinwe endaweni yokugcina impahla itholakale ukuthi inokulahlekelwa okungaphansi kwe-1% kwe-chlorine etholakalayo ngemva konyaka owodwa.

(6) Umkhiqizo uqinile, ungenziwa ube yimpuphu emhlophe noma izinhlayiya, ukupakisha nokuthuthwa okulula, kodwa futhi kulula kubasebenzisi ukukhetha nokusebenzisa.

UmkhiqizoAisicelo:

I-DCCNa uhlobo lokubulala amagciwane olusebenzayo kanye ne-fungicide, olunokuncibilika okuphezulu emanzini, ikhono lokubulala amagciwane elihlala isikhathi eside kanye nobuthi obuphansi, ngakho-ke isetshenziswa kabanzi njengesibulala-magciwane samanzi okuphuza kanye nesibulala-magciwane sasekhaya. I-DCCNa ifaka i-hydrolyzes i-acid e-hypochlorous emanzini futhi ingathatha indawo ye-acid e-hypochlorous kwezinye izimo, ngakho-ke ingasetshenziswa njenge-bleach. Ngaphezu kwalokho, ngoba i-DCCNa ingakhiqizwa ngezinga elikhulu futhi intengo iphansi, isetshenziswa kabanzi ezimbonini eziningi:

1) i-ejenti yokwelapha uboya elwa nokushwabana;

2) Ukuhlanza izimboni zezindwangu;

3) Ukubulala amagciwane kanye nokubulala amagciwane embonini yezolimo zasemanzini;

4) Ukuhlanza indle yomphakathi;

5) Ukwelashwa kwamanzi ajikelezayo ezimbonini;

6) Ukuhlanza nokubulala amagciwane embonini yokudla nasezindaweni zomphakathi.

Indlela yokulungiselela:

(1) Ukungahlanganisi i-dichlorylisocyanuric acid (indlela ye-chloride) i-cyanuric acid kanye ne-caustic soda ngokwesilinganiso se-1:2 molar kusisombululo samanzi, esifakwe i-chlorine ku-dichloroisocyanuric acid, ukuhlunga kwe-slurry ukuthola ikhekhe lokuhlunga le-dichloroisocyanuric acid kungagezwa ngokuphelele ngamanzi, kususwe ikhekhe i-sodium chloride, i-dichloroisocyanuric acid. I-dichloroisocyanurate emanzi ixutshwe namanzi ku-slurry, noma ifakwe ku-liquor ye-sodium dichloroisocyanurate, futhi ukusabela kwe-neutralization kwenziwa ngokuphonsa i-caustic soda ku-molar ratio engu-1:1. Isixazululo sokusabela siyapholiswa, sicwebezelwe bese sihlungwa ukuze sithole i-sodium dichloroisocyanurate emanzi, bese yomiswa ukuze ithole i-powdered.i-sodium dichloroisocyanuratenoma i-hydrate yayo.

(2) Indlela ye-sodium hypochlorite yenziwa okokuqala nge-caustic soda kanye ne-chlorine gas reaction ukuze kukhiqizwe isixazululo se-sodium hypochlorite ngokuhlushwa okufanele. I-Chemicalbook ingahlukaniswa ngezinhlobo ezimbili zenqubo enohlu oluphezulu noluphansi ngokuya ngokuhlushwa okuhlukile kwesisombululo se-sodium hypochlorite. I-sodium hypochlorite isabela ne-cyanuric acid ukuze ikhiqize i-dichloroisocyanuric acid kanye ne-sodium hydroxide. Ukuze kulawulwe inani le-pH lokusabela, igesi ye-chlorine ingangezwa ukuze kwenziwe i-sodium hydroxide kanye negesi ye-chlorine ukuze kukhiqizwe i-sodium hypochlorite ukuthi iqhubeke nokubamba iqhaza ekusabeleni, ukuze kusetshenziswe ngokugcwele izinto zokusetshenziswa zokusabela. Kodwa ngenxa yokuthi igesi ye-chlorine ihilelekile ekusabeleni kwe-chlorination, izidingo zokulawula ku-cyanuric acid yezinto zokusetshenziswa kanye nezimo zokusebenza zokusabela ziqinile, ngaphandle kwalokho kulula ukwenzeka ingozi yokuqhuma kwe-nitrogen trichloride; Ngaphezu kwalokho, i-inorganic acid (njenge-hydrochloric acid) ingasetshenziswa futhi ukuqeda indlela, engabandakanyi igesi ye-chlorine ngqo ekusabeleni, ngakho-ke ukusebenza kulula ukuyilawula, kodwa ukusetshenziswa kwe-sodium hypochlorite yezinto zokusetshenziswa akukapheleli.

Izimo zokugcina kanye nezokuthutha kanye nokupakishwa:

I-sodium dichloroisocyanurate ipakishwa ezikhwameni ezilukiwe, emabhakedeni epulasitiki noma emabhakedeni ekhadibhodi: 25KG/ isikhwama, 25KG/ ibhakedeni, 50KG/ ibhakedeni.
