SODIUM DICHLOROISOCYANURATE

Kapangidwe ka thupi ndi mankhwala:

Ufa woyera wa kristalo, wokhala ndi fungo lamphamvu la chlorine, wokhala ndi 60% ~ 64.5% ya chlorine yogwira ntchito. Ndi wokhazikika ndipo umasungidwa pamalo otentha komanso onyowa. Kuchuluka kwa chlorine kogwira ntchito kumachepa ndi 1% yokha. Kusungunuka mosavuta m'madzi, kusungunuka kwa 25% (25℃). Yankho lake ndi lofooka pang'ono, ndipo pH ya yankho la 1% lamadzi ndi 5.8 ~ 6.0. pH imasintha pang'ono pamene kuchuluka kwake kukukwera. Hypochlorous acid imapangidwa m'madzi, ndipo hydrolysis yake yokhazikika ndi 1 × 10-4, yomwe ndi yokwera kuposa chloramine T. Kukhazikika kwa yankho lamadzi ndi kofooka, ndipo kutayika kwa chlorine yogwira ntchito kumafulumira motsatira UV Chemicalbook. Kuchuluka kochepa kumatha kupha mwachangu mitundu yosiyanasiyana ya mabakiteriya, bowa, mavairasi, kachilombo ka hepatitis kali ndi zotsatira zapadera. Ili ndi mawonekedwe a kuchuluka kwa chlorine, mphamvu yamphamvu ya bactericidal, njira yosavuta komanso mtengo wotsika. Kuopsa kwa sodium dichloroisocyanurate ndikotsika, ndipo mphamvu ya bactericidal ndi yabwino kuposa ya ufa wothira ndi chloramine-T. Chothandizira kusuta cha chlorine kapena chothandizira kusuta cha acid chingapangidwe posakaniza chothandizira kuchepetsa zitsulo kapena chogwirizanitsa asidi ndi potassium permanganate ndisodium dichloroisocyanurateUfa wouma. Fumigant wamtunduwu umatulutsa mpweya wamphamvu wopha mabakiteriya ukayaka.

Zinthu zomwe zili mu malonda:

(1) Mphamvu yoyeretsa bwino komanso yophera tizilombo toyambitsa matenda. Kuchuluka kwa chlorine kogwira ntchito mu DCCNa yoyera ndi 64.5%, ndipo kuchuluka kwa chlorine kogwira ntchito muzinthu zapamwamba kwambiri ndi kopitilira 60%, komwe kumakhala ndi mphamvu yoyeretsa bwino komanso yophera tizilombo toyambitsa matenda. Pa 20ppm, kuchuluka kwa sterilization kumafika 99%. Kumapha mitundu yonse ya mabakiteriya, algae, bowa ndi majeremusi.

(2) Poizoni wake ndi wochepa kwambiri, mlingo wapakati wakupha (LD50) ndi wokwera kufika pa 1.67g/kg (mlingo wapakati wakupha wa trichloroisocyanuric acid ndi 0.72-0.78 g/kg yokha). Kugwiritsa ntchito DCCNa pochiza matenda ndi kuchiza matenda a chakudya ndi madzi akumwa kwakhala kovomerezeka kwa nthawi yayitali kunyumba ndi kunja.

(3) Pogwiritsa ntchito njira zosiyanasiyana, mankhwalawa sangagwiritsidwe ntchito kokha m'makampani opanga zakudya ndi zakumwa komanso m'madzi akumwa, kuyeretsa ndi kupha tizilombo toyambitsa matenda m'malo opezeka anthu ambiri, m'mafakitale oyendera madzi, kupha tizilombo toyambitsa matenda m'nyumba za anthu wamba, komanso m'makampani opanga zaulimi wa m'madzi.

(4) Kuchuluka kwa kugwiritsa ntchito chlorine moyenera ndi kwakukulu, ndipo kusungunuka kwa DCCNa m'madzi kumakhala kwakukulu kwambiri. Pa 25℃, madzi aliwonse a 100mL amatha kusungunula 30g DCCNa. Ngakhale mumadzi okhala ndi kutentha kwa madzi kotsika ngati 4°C, DCCNa imatha kutulutsa mwachangu chlorine yonse yogwira ntchito yomwe ili nayo, ndikugwiritsa ntchito bwino mankhwala ake ophera tizilombo toyambitsa matenda komanso mphamvu yopha mabakiteriya. Zinthu zina zolimba zokhala ndi chlorine (kupatula chloro-isocyanuric acid) zimakhala ndi chlorine yotsika kwambiri kuposa DCCNa chifukwa cha kusungunuka kochepa kapena kutulutsidwa pang'onopang'ono kwa chlorine yomwe ili mkati mwake.

(5) Kukhazikika kwabwino. Chifukwa cha kukhazikika kwakukulu kwa mphete za triazine muzinthu za chloro-isocyanuric acid, mawonekedwe a DCCNa ndi okhazikika. DCCNa youma yosungidwa m'nyumba yosungiramo katundu yapezeka kuti ili ndi kutayika kwa chlorine yosakwana 1% patatha chaka chimodzi.

(6) Chogulitsacho ndi cholimba, chingapangidwe kukhala ufa woyera kapena tinthu tating'onoting'ono, chosavuta kulongedza ndi kunyamula, komanso chosavuta kugwiritsa ntchito kwa ogwiritsa ntchito.

ChogulitsaAkubwerezabwereza:

DCCNa ndi mtundu wa mankhwala ophera tizilombo toyambitsa matenda komanso fungicide ogwira ntchito bwino, omwe amasungunuka kwambiri m'madzi, amatha kupha tizilombo toyambitsa matenda kwa nthawi yayitali komanso poizoni wochepa, kotero amagwiritsidwa ntchito kwambiri ngati mankhwala ophera tizilombo toyambitsa matenda m'madzi akumwa komanso mankhwala ophera tizilombo toyambitsa matenda m'nyumba. DCCNa imathira asidi wochepa m'madzi ndipo nthawi zina imatha kulowa m'malo mwa asidi wochepa m'madzi, kotero ingagwiritsidwe ntchito ngati bleach. Komanso, chifukwa DCCNa imatha kupangidwa pamlingo waukulu ndipo mtengo wake ndi wotsika, imagwiritsidwa ntchito kwambiri m'mafakitale ambiri:

1) mankhwala oletsa kufupika kwa ubweya;

2) Kuyeretsa nsalu m'makampani opanga nsalu;

3) Kuyeretsa ndi kupha tizilombo toyambitsa matenda m'makampani a ulimi wa nsomba;

4) Kuyeretsa ukhondo wa anthu wamba;

5) Kukonza madzi ozungulira mafakitale;

6) Kuyeretsa ndi kupha tizilombo toyambitsa matenda m'makampani ogulitsa chakudya ndi malo opezeka anthu ambiri.

Njira yokonzekera:

(1) Kuletsa asidi ya Dichlorylisocyanuric (njira ya chloride) cyanuric acid ndi caustic soda molingana ndi chiŵerengero cha 1:2 molar mu yankho lamadzi, lothiridwa ndi dichloroisocyanuric acid, kusefa kwa slurry kuti mupeze dichloroisocyanuric acid fyuluta keke ikhoza kutsukidwa mokwanira ndi madzi, kuchotsa keke sodium chloride, dichloroisocyanuric acid. Dichloroisocyanurate yonyowa idasakanizidwa ndi madzi mu slurry, kapena kuyikidwa mu mowa wotsekemera wa sodium dichloroisocyanurate, ndipo neutralization reaction idachitika pogwetsa caustic soda pa chiŵerengero cha molar cha 1:1. Yankho la reaction limaziziritsidwa, limapangidwa ndi crystallized ndikusefedwa kuti likhale lonyowa la sodium dichloroisocyanurate, lomwe kenako limauma kuti likhale ufa.sodium dichloroisocyanuratekapena madzi ake.

(2) Njira ya sodium hypochlorite imapangidwa koyamba ndi caustic soda ndi chlorine gas reaction kuti ipange sodium hypochlorite solution yokhala ndi kuchuluka koyenera. Chemicalbook ingagawidwe m'mitundu iwiri ya njira yokhala ndi kuchuluka kwakukulu ndi kochepa malinga ndi kuchuluka kosiyana kwa sodium hypochlorite solution. Sodium hypochlorite imagwira ntchito ndi cyanuric acid kuti ipange dichloroisocyanuric acid ndi sodium hydroxide. Pofuna kuwongolera pH ya reaction, chlorine gas ikhoza kuwonjezeredwa kuti sodium hydroxide ndi chlorine gas kuti ipange sodium hypochlorite zipitirire kutenga nawo mbali mu reaction, kuti zigwiritse ntchito mokwanira reaction raw fruit tools. Koma chifukwa chlorine gas imagwira ntchito mu chlorination reaction, zofunikira zowongolera pa raw material cyanuric acid ndi momwe zimagwirira ntchito ndizovuta, apo ayi zimakhala zosavuta kuchitika nitrogen trichloride explosion explosion ngozi; Kuphatikiza apo, inorganic acid (monga hydrochloric acid) ingagwiritsidwenso ntchito kusokoneza njira, yomwe siimaphatikizapo chlorine gas mwachindunji mu reaction, kotero opaleshoniyo ndi yosavuta kuyilamulira, koma kugwiritsa ntchito sodium hypochlorite ya raw material sikukwanira.

Zinthu zosungiramo ndi zoyendera & Kulongedza:

Sodium dichloroisocyanurate imapakidwa m'matumba opangidwa ndi nsalu, zidebe zapulasitiki kapena zidebe za makatoni: 25KG/thumba, 25KG/chidebe, 50KG/chidebe.
