Thepa ea 'mele le ea lik'hemik'hale:

Phofo e tšoeu e kristale, e nang le monko o matla oa chlorine, e nang le chlorine e sebetsang hantle ea 60% ~ 64.5%. E tsitsitse ebile e bolokiloe sebakeng se chesang le se mongobo. Sekhahla sa chlorine se sebetsang se fokotseha ka 1% feela. E qhibiliha habonolo metsing, ho qhibiliha ha 25% (25℃). Tharollo e na le asiti e fokolang, 'me pH ea tharollo ea metsi ea 1% ke 5.8 ~ 6.0. pH ha e fetohe haholo ha mahloriso a ntse a eketseha. Asiti ea Hypochlorous e hlahisoa ka metsing, 'me hydrolysis ea eona e sa fetoheng ke 1 × 10-4, e leng e phahameng ho feta chloramine T. Botsitso ba tharollo ea metsi bo fokola, 'me tahlehelo ea chlorine e sebetsang e potlaka tlas'a UV Chemicalbook. Mahloriso a tlase a ka bolaea mefuta e fapaneng ea li-propagule tsa baktheria, li-fungus, livaerase, kokoana-hloko ea hepatitis e na le litlamorao tse ikhethang kapele. E na le litšobotsi tsa chlorine e ngata, ketso e matla ea bactericidal, ts'ebetso e bonolo le theko e tlase. Chefo ea sodium dichloroisocyanurate e tlase, 'me phello ea bactericidal e betere ho feta ea phofo ea bleaching le chloramine-T. Moemeli oa ho fufutsa ka chlorine kapa moemeli oa ho fufutsa ka asiti o ka etsoa ka ho kopanya moemeli oa ho fokotsa tšepe kapa motsoako oa asiti le potassium permanganate lesodium dichloroisocyanuratephofo e omileng. Mofuta ona wa sebolaya-dikokwana-hloko o tla hlahisa kgase e matla e bolayang dikokwana-hloko kamora ho hotetswa.

Likarolo tsa sehlahisoa:

(1) Bokgoni bo matla ba ho ntsha dikokwana-hloko le ho dibolaya dikokwana-hloko. Dikahare tse sebetsang tsa chlorine tsa DCCNa e hlwekileng ke 64.5%, mme dikahare tse sebetsang tsa chlorine tsa dihlahiswa tsa boleng bo hodimo di feta 60%, e leng se nang le phello e matla ya ho ntsha dikokwana-hloko le ho dibolaya dikokwana-hloko. Ka 20ppm, sekgahla sa ho ntsha dikokwana-hloko se fihla ho 99%. Se na le phello e matla ya ho bolaya mefuta yohle ya dibaktheria, bolele, di-fungus le dikokwana-hloko.

(2) Chefo ea eona e tlase haholo, tekanyo e bolaeang ea bohareng (LD50) e holimo ho 1.67g/kg (tekanyo e bolaeang ea trichloroisocyanuric acid ke 0.72-0.78 g/kg feela). Tšebeliso ea DCCNa ho bolaeeng le ho bolaeeng lijo le metsi a nooang e se e amohetsoe ka nako e telele lapeng le kantle ho naha.

(3) Ka mefuta e mengata ea ts'ebeliso, sehlahisoa sena se ke ke sa sebelisoa feela indastering ea ho lokisa lijo le lino le ho hloekisa metsi a nooang, ho hloekisa le ho bolaea likokoana-hloko libakeng tsa sechaba, kalafong ea metsi a potolohang indastering, ho hloekisa likhoerekhoere malapeng a sechaba, ho hloekisa likhoerekhoere indastering ea temo ea litlhapi le hona ho sebelisoa haholo.

(4) Sekhahla se sebetsang sa tšebeliso ea chlorine se phahame, 'me ho qhibiliha ha DCCNa ka metsing ho phahame haholo. Ka 25℃, metsi a mang le a mang a 100mL a ka qhala 30g DCCNa. Esita le ka tharollong ea metsi e nang le mocheso oa metsi o tlase ho 4°C, DCCNa e ka lokolla chlorine eohle e sebetsang eo e nang le eona kapele, e sebelisa ka botlalo ho bolaea likokoana-hloko le phello ea ho bolaea likokoana-hloko. Lihlahisoa tse ling tse tiileng tse nang le chlorine (ntle le chloro-isocyanuric acid) li na le boleng bo tlase haholo ba chlorine ho feta DCCNa ka lebaka la ho qhibiliha ho tlase kapa ho lokolloa butle ha chlorine e ho tsona.

(5) Botsitso bo botle. Ka lebaka la botsitso bo phahameng ba masale a triazine lihlahisoa tsa chloro-isocyanuric acid, thepa ea DCCNa e tsitsitse. DCCNa e omileng e bolokiloeng ka tlung ea polokelo e fumanoe e lahleheloa ke chlorine e ka tlase ho 1% kamora selemo se le seng.

(6) Sehlahisoa se tiile, se ka etsoa phofo e tšoeu kapa likaroloana, se ka pakoa le ho tsamaisoa habonolo, empa hape se loketse basebelisi ho se khetha le ho se sebelisa.

DCCNa ke mofuta oa ho bolaea likokoana-hloko le ho bolaea fungus ka katleho, o nang le ho qhibiliha ho hoholo metsing, bokhoni ba ho bolaea likokoana-hloko bo nkang nako e telele le chefo e tlase, kahoo o sebelisoa haholo e le sebolaya-likokoana-hloko sa metsi a nooang le sebolaya-likokoana-hloko sa lapeng. DCCNa e hydrolyzes hypochlorous acid ka metsing 'me e ka nkela acid e hypochlorous sebaka maemong a mang, kahoo e ka sebelisoa e le bleach. Ho feta moo, hobane DCCNa e ka hlahisoa ka bongata 'me theko e tlase, e sebelisoa haholo liindastering tse ngata:

1) sesebelisoa sa kalafo se thibelang ho fokotseha ha boea;

2) Ho soeufatsa bakeng sa indasteri ea masela;

3) Ho hlwekisa le ho bolaea likokoana-hloko indastering ea temo ea litlhapi;

4) Ho bolaea likokoana-hloko tsa bohloeki ba sechaba;

5) Phekolo ea metsi a potolohang indastering;

6) Ho hlwekisa le ho bolaea likokoana-hloko indastering ea lijo le libakeng tsa sechaba.

Mokhoa oa ho lokisa:

(1) Ho se neutralization ea dichlorylisocyanuric acid (mokhoa oa chloride) cyanuric acid le caustic soda ho latela karolelano ea 1:2 molar ka har'a tharollo ea metsi, e nang le chlorine ho dichloroisocyanuric acid, ho sefa ha slurry ho fumana dichloroisocyanuric acid filthara kuku e ka hlatsuoa ka botlalo ka metsi, ho tlosoa ka kuku sodium chloride, dichloroisocyanuric acid. Dichloroisocyanurate e metsi e ne e kopantsoe le metsi ka har'a slurry, kapa e kenngoa ka har'a joala ba 'mè ba sodium dichloroisocyanurate,' me karabelo ea ho se neutralization e entsoe ka ho lahla caustic soda ka karolelano ea molar ea 1:1.
