Sodium Dichloroisocyanurate

Hunhu hwemuviri uye hwemakemikari:

Upfu hwema hwema hwema hwe chlorine, hune 60% ~ 64.5% chlorine inoshanda. Hunogara kwenguva refu uye hunochengetwa munzvimbo inopisa uye ine hunyoro. Hunhu hwe chlorine inoshanda hunoderera ne1% chete. Hunonyungudika nyore nyore mumvura, kunyungudika kwe25% (25℃). Mushonga wacho une acidity shoma, uye pH ye1% yemvura inonyungudika i5.8 ~ 6.0. pH haishanduki zvakanyanya sezvo huwandu huchikwira. Hypochlorous acid inogadzirwa mumvura, uye hydrolysis yayo inoramba iripo i1 × 10-4, iyo yakakwira kupfuura chloramine T. Kugadzikana kwemvura inonyungudika kwakashata, uye kurasikirwa kwechlorine inoshanda kunokurumidza pasi peUV Chemicalbook. Hunhu hwakaderera hunogona kuuraya nekukurumidza mhando dzakasiyana dzemabhakitiriya, fungi, mavhairasi, hepatitis virus ine mhedzisiro yakakosha. Ine hunhu hwehuwandu hwakawanda hwe chlorine, simba rekuuraya mabhakitiriya, maitiro ari nyore uye mutengo wakachipa. Chepfu ye sodium dichloroisocyanurate yakaderera, uye mhedzisiro yebhakitiriya iri nani pane ye bleaching powder ne chloramine-T. Chlorine fuming agent kana acid fuming agent inogona kugadzirwa nekusanganisa simbi reduction agent kana acid synergist ne potassium permanganate uyesodium dichloroisocyanurateupfu hwakaoma. Rudzi urwu rwemushonga wekufukisa huchaburitsa gasi rakasimba rinouraya mabhakitiriya mushure mekubatidzwa.

Zvimiro zvechigadzirwa:

(1) Kugona kwakasimba kwekubvisa utachiona uye kuuraya utachiona. Kuwanda kwechlorine muDCCNa yakachena i64.5%, uye huwandu hwechlorine hunoshanda muzvigadzirwa zvepamusoro-soro hunopfuura 60%, izvo zvine simba rekubvisa utachiona uye kuuraya utachiona. Pa20ppm, mwero wekubvisa utachiona unosvika 99%. Ine simba guru rekuuraya marudzi ese emabhakitiriya, algae, fungi nehutachiona.

(2) Chepfu yayo yakaderera zvikuru, chiyero chepakati chekuuraya (LD50) chakakwira kusvika 1.67g/kg (chiyero chepakati chekuuraya che trichloroisocyanuric acid i0.72-0.78 g/kg chete). Kushandiswa kweDCCNa mukuuraya uye kuuraya chikafu nemvura yekunwa kwagara kuchibvumidzwa munyika nekune dzimwe nyika.

(3) Chigadzirwa ichi chinoshandiswa zvakasiyana-siyana, kwete chete muindasitiri yekugadzira chikafu nezvinwiwa uye mukuchenesa mvura yekunwa, kuchenesa nekuchenesa nzvimbo dzeveruzhinji, mukurapa mvura inoyerera mumaindasitiri, kuchenesa dzimba, uye kuchenesa indasitiri yekurima hove.

(4) Kushandiswa kwechlorine kunobudirira kwakanyanya, uye kunyungudika kweDCCNa mumvura kwakanyanya. Pa25℃, mvura yega yega ye100mL inogona kunyungudutsa 30g DCCNa. Kunyangwe mumvura ine tembiricha yakaderera se4°C, DCCNa inogona kuburitsa chlorine yese inoshanda iri mairi nekukurumidza, ichishandisa zvizere mushonga wayo wekuuraya utachiona uye kuuraya mabhakitiriya. Zvimwe zvigadzirwa zvine chlorine yakasimba (kunze kwechloro-isocyanuric acid) zvine chlorine yakaderera kupfuura DCCNa nekuda kwekunyungudika kushoma kana kuburitswa zvishoma nezvishoma kwechlorine iri mairi.

(5) Kugadzikana kwakanaka. Nekuda kwekugadzikana kwakanyanya kwetriazine rings muzvigadzirwa zve chloro-isocyanuric acid, hunhu hweDCCNa hwakagadzikana. Dry DCCNa yakachengetwa mudura yakaonekwa kuti ine kurasikirwa ne1% yechlorine iripo mushure megore rimwe chete.

(6) Chigadzirwa chacho chakasimba, chinogona kugadzirwa kuita upfu huchena kana zvidimbu, kurongedza nekutakura zviri nyore, asiwo zviri nyore kuti vashandisi vasarudze uye vashandise.

ChigadzirwaAkushanda:

DCCNa imhando yemishonga inouraya utachiona uye inouraya fungi inoshanda, ine kunyunguduka kwakanyanya mumvura, kugona kwayo kubvisa hutachiona kwenguva refu uye ine chepfu shoma, saka inoshandiswa zvakanyanya semushonga wekuuraya utachiona mumvura yekunwa uye mushonga wekuuraya utachiona wepamba. DCCNa inonyungudutsa acid isina chlorous mumvura uye inogona kutsiva acid isina chlorous mune dzimwe nguva, saka inogona kushandiswa sebleach. Uyezve, nekuti DCCNa inogona kugadzirwa zvakanyanya uye mutengo wayo wakaderera, inoshandiswa zvakanyanya mumaindasitiri mazhinji:

1) mushonga wekurapa mvere unodzivirira kuderera;

2) Kuchenesa machira eindasitiri yemachira;

3) Kuchenesa uye kubvisa utachiona muindasitiri yekurima hove;

4) Kuchenesa tsvina kubva muhutsanana hwevanhu;

5) Kurapa mvura inotenderera mumaindasitiri;

6) Kuchenesa nekubvisa utachiona muindasitiri yechikafu nenzvimbo dzeveruzhinji.

Nzira yekugadzirira:

(1) Kubvisa Dichlorylisocyanuric acid (nzira yechloride) cyanuric acid ne caustic soda zvichienderana ne 1:2 molar ratio mu aqueous solution, chlorinated ku dichloroisocyanuric acid, slurry filtration kuti uwane dichloroisocyanuric acid filter keke inogona kusukwa zvizere nemvura, kubvisa keke sodium chloride, dichloroisocyanuric acid. Dichloroisocyanurate yakanyorova yakasanganiswa nemvura mu slurry, kana kuiswa mu mother liquor ye sodium dichloroisocyanurate, uye neutralization reaction yakaitwa nekudonhedza caustic soda pa molar ratio ye 1:1. Mhinduro yacho inotonhorerwa, inonatswa uye inoseferwa kuti iwane sodium dichloroisocyanurate yakanyorova, iyo inobva yaoma kuti iite upfu.sodium dichloroisocyanuratekana kuti hydrate yayo.

(2) Nzira yeSodium hypochlorite inotanga kugadzirwa ne caustic soda ne chlorine gas reaction kuti igadzire sodium hypochlorite solution ine concentration yakakodzera. Chemicalbook inogona kukamurwa kuita mhando mbiri dzemaitiro ane concentration yakakwira neyakaderera zvichienderana nehuwandu hwakasiyana hwe sodium hypochlorite solution. Sodium hypochlorite inosangana ne cyanuric acid kuti igadzire dichloroisocyanuric acid ne sodium hydroxide. Kuti idzore pH value ye reaction, chlorine gas inogona kuwedzerwa kuti sodium hydroxide ne chlorine gas igadzire sodium hypochlorite irambe ichibatanidzwa mu reaction, kuitira kuti ishandise zvizere reaction raw materials. Asi nekuda kwekuti chlorine gas inobatanidzwa mu chlorination reaction, zvinodiwa zvekutonga pa raw material cyanuric acid nemamiriro ekushanda kwe reaction acho akaomarara, zvikasadaro zviri nyore kuitika nitrogen trichloride explosion accident; Pamusoro pezvo, inorganic acid (senge hydrochloric acid) inogonawo kushandiswa kudzima nzira iyi, iyo isingasanganisire chlorine gas zvakananga mu reaction, saka operation yacho iri nyore kudzora, asi kushandiswa kwe raw material sodium hypochlorite hakuna kukwana.

Mamiriro ekuchengetedza nekufambisa & Kurongedza:

Sodium dichloroisocyanurate inoiswa mumabhegi akarukwa, mabhaketi epurasitiki kana mabhaketi emakadhibhodhi: 25KG/bhegi, 25KG/bhaketi, 50KG/bhaketi.
