SODIUM DICHLOROISOCYANURATE

Cov khoom siv lub cev thiab tshuaj lom neeg:

Cov hmoov crystalline dawb, muaj ntxhiab tsw chlorine muaj zog, muaj 60% ~ 64.5% chlorine zoo. Nws ruaj khov thiab khaws cia rau hauv qhov chaw kub thiab noo. Cov tshuaj chlorine zoo txo ​​qis tsuas yog 1%. Yooj yim yaj hauv dej, solubility ntawm 25% (25 ℃). Cov tshuaj yog weakly acidic, thiab pH ntawm 1% aqueous kua yog 5.8 ~ 6.0. pH hloov me ntsis thaum qhov concentration nce. Hypochlorous acid yog tsim nyob rau hauv dej, thiab nws hydrolysis tas mus li yog 1 × 10-4, uas yog siab dua chloramine T. Qhov ruaj khov ntawm cov tshuaj aqueous tsis zoo, thiab qhov poob ntawm cov tshuaj chlorine zoo nrawm dua nyob rau hauv UV Chemicalbook. Qhov concentration qis tuaj yeem tua ntau yam kab mob propagules, fungi, viruses, hepatitis virus muaj cov teebmeem tshwj xeeb. Nws muaj cov yam ntxwv ntawm cov tshuaj chlorine siab, muaj zog bactericidal kev ua, yooj yim txheej txheem thiab pheej yig. Qhov tshuaj lom ntawm sodium dichloroisocyanurate qis dua, thiab cov nyhuv bactericidal zoo dua li ntawm cov hmoov bleaching thiab chloramine-T. Cov tshuaj chlorine fuming agent lossis acid fuming agent tuaj yeem ua los ntawm kev sib xyaw cov tshuaj txo cov hlau lossis cov tshuaj ua ke nrog cov kua qaub nrog potassium permanganate thiabsodium dichloroisocyanuratehmoov qhuav. Hom tshuaj fumigant no yuav tsim cov pa roj bactericidal muaj zog tom qab hlawv.

Cov yam ntxwv ntawm cov khoom:

(1) Muaj peev xwm tua kab mob thiab tua kab mob tau zoo. Cov tshuaj chlorine uas muaj txiaj ntsig zoo ntawm DCCNa ntshiab yog 64.5%, thiab cov tshuaj chlorine uas muaj txiaj ntsig zoo ntawm cov khoom zoo yog ntau dua 60%, uas muaj cov nyhuv tua kab mob thiab tua kab mob zoo. Ntawm 20ppm, tus nqi tua kab mob ncav cuag 99%. Nws muaj cov nyhuv tua kab mob zoo rau txhua hom kab mob, algae, fungi thiab kab mob.

(2) Nws cov tshuaj lom yog qis heev, qhov nruab nrab ntawm cov tshuaj lom neeg tuag taus (LD50) yog siab txog 1.67g / kg (qhov nruab nrab ntawm cov tshuaj lom neeg tuag taus ntawm trichloroisocyanuric acid tsuas yog 0.72-0.78 g / kg). Kev siv DCCNa hauv kev tua kab mob thiab kev tua kab mob ntawm cov zaub mov thiab dej haus tau ntev tau pom zoo hauv tsev thiab txawv teb chaws.

(3) Ntau yam kev siv, cov khoom tsis yog tsuas yog siv tau rau hauv kev lag luam ua zaub mov thiab dej haus thiab kev tua kab mob hauv dej haus, kev ntxuav thiab tua kab mob rau pej xeem, hauv kev kho dej hauv kev lag luam, kev tua kab mob hauv tsev neeg, kev tua kab mob hauv kev lag luam aquaculture kuj siv dav.

(4) Tus nqi siv chlorine zoo yog siab, thiab DCCNa solubility hauv dej yog siab heev. Ntawm 25 ℃, txhua 100mL dej tuaj yeem yaj 30g DCCNa. Txawm tias nyob rau hauv cov kua dej nrog dej kub qis li 4 ° C, DCCNa tuaj yeem tso tawm tag nrho cov chlorine zoo uas nws muaj, ua kom siv tag nrho nws cov tshuaj tua kab mob thiab cov kab mob. Lwm cov khoom muaj chlorine khov (tshwj tsis yog chloro-isocyanuric acid) muaj cov nqi chlorine qis dua DCCNa vim tias solubility qis lossis qeeb tso tawm cov chlorine uas muaj nyob hauv lawv.

(5) Kev ruaj khov zoo. Vim yog qhov ruaj khov siab ntawm cov nplhaib triazine hauv cov khoom chloro-isocyanuric acid, cov khoom DCCNa ruaj khov. DCCNa qhuav khaws cia rau hauv lub tsev rau khoom tau txiav txim siab tias muaj kev poob tsawg dua 1% ntawm cov chlorine muaj tom qab 1 xyoos.

(6) Cov khoom yog khov kho, tuaj yeem ua rau cov hmoov dawb lossis cov khoom me me, yooj yim ntim thiab thauj mus los, tab sis kuj yooj yim rau cov neeg siv xaiv thiab siv.

KhoomAdaim ntawv thov:

DCCNa yog ib hom tshuaj tua kab mob thiab tshuaj tua kab mob zoo, nws yaj tau zoo hauv dej, tua tau kab mob ntev thiab tsis muaj tshuaj lom, yog li nws siv dav ua tshuaj tua kab mob hauv dej haus thiab tshuaj tua kab mob hauv tsev. DCCNa hydrolyzes hypochlorous acid hauv dej thiab qee zaum hloov hypochlorous acid, yog li nws siv tau ua tshuaj dawb. Ntxiv mus, vim DCCNa tuaj yeem tsim tau ntau yam thiab tus nqi qis, nws siv dav hauv ntau yam lag luam:

1) tus neeg sawv cev kho mob tiv thaiv kev ntsws ntawm cov plaub mos mos;

2) Tshuaj dawb rau kev lag luam textile;

3) Kev ua kom tsis muaj menyuam thiab kev tua kab mob ntawm kev lag luam aquaculture;

4) Kev ntxuav tu cev pej xeem;

5) Kev kho dej ncig hauv kev lag luam;

6) Kev ntxuav thiab 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 piv rau hauv cov kua dej, chlorinated rau dichloroisocyanuric acid, slurry lim 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 dichloroisocyanurate ntub tau sib xyaw nrog dej hauv cov slurry, lossis muab tso rau hauv cov kua dej ntawm sodium dichloroisocyanurate, thiab qhov kev cuam tshuam neutralization tau ua tiav los ntawm kev poob caustic soda ntawm molar piv ntawm 1: 1. Cov tshuaj tiv thaiv tau txias, crystallized thiab lim kom tau txais sodium dichloroisocyanurate ntub, uas tom qab ntawd qhuav kom tau hmoov.sodium dichloroisocyanuratelos yog nws cov hydrates.

(2) Txoj kev Sodium hypochlorite yog ua ntej los ntawm caustic soda thiab chlorine roj reaction los tsim cov sodium hypochlorite kua nrog cov concentration tsim nyog. Chemicalbook tuaj yeem muab faib ua ob hom txheej txheem nrog siab thiab qis concentration raws li qhov sib txawv concentration ntawm sodium hypochlorite kua. Sodium hypochlorite reacts nrog cyanuric acid los tsim dichloroisocyanuric acid thiab sodium hydroxide. Yuav kom tswj tau tus nqi pH ntawm cov tshuaj tiv thaiv, chlorine roj tuaj yeem ntxiv los ua sodium hydroxide thiab chlorine roj los tsim sodium hypochlorite txuas ntxiv koom nrog hauv cov tshuaj tiv thaiv, yog li ua kom siv tag nrho cov khoom siv tshuaj tiv thaiv. Tab sis vim tias chlorine roj koom nrog hauv cov tshuaj tiv thaiv chlorination, cov kev cai tswj hwm ntawm cov khoom siv raw cyanuric acid thiab cov xwm txheej ua haujlwm ntawm cov tshuaj tiv thaiv yog qhov nruj heev, txwv tsis pub nws yooj yim tshwm sim nitrogen trichloride tawg; Tsis tas li ntawd, inorganic acid (xws li hydrochloric acid) kuj tseem siv tau los neutralize txoj kev, uas tsis koom nrog chlorine roj ncaj qha 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.

Cov xwm txheej ntawm kev khaws cia thiab kev thauj mus los & Ntim:

Sodium dichloroisocyanurate tau ntim rau hauv cov hnab woven, cov thoob yas lossis cov thoob cardboard: 25KG / hnab, 25KG / thoob, 50KG / thoob.
