Yog tias koj yuav mus rau cov lag luam wholesale bulk dicyandiamide ua nyob rau hauv Suav teb, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

Cov tsos mob: Dawb rhombic crystalline hmoov
Melting point: 207-211℃(decomposes thaum melting; sublimes ntawm 220 degree)
Ceev: 1.40 g / cm³ (25 degree)
Solubility: Sparingly soluble hauv dej txias (2.26 g / 100 g ntawm 13 degree); yooj yim soluble hauv dej kub, ethanol, thiab DMF; xyaum insoluble hauv benzene, diethyl ether, thiab chloroform
Acidity / Alkalinity: Aqueous tov yog weakly alkaline

Thermal stability: ruaj khov ntawm chav tsev kub hauv daim ntawv qhuav; aqueous daws decompose maj mam siab tshaj 80 degree, tso ammonia; decomposes rau hauv melamine thiab ammonia thaum rhuab saum 250 degree.
Cov tshuaj tiv thaiv condensation: tuaj yeem ua rau cov aldehydes (xws li formaldehyde) los tsim dicyandiamide-formaldehyde resins.
Kev tsim ntsev: nthuav tawm tsis muaj zog alkalinity thiab tuaj yeem nruab nrab los ntawm inorganic acids los tsim ntau yam guanidine ntsev (xws li, guanidine nitrate, guanidine hydrochloride).
Cov tshuaj tiv thaiv phom sij: Ua phem heev- lossis tuaj yeem tawg tau - thaum ntsib cov oxidizing muaj zog (xws li ammonium nitrate lossis potassium chlorate); reacts nrog cov kua qaub kom tso cov pa phem heev hydrogen cyanide gas.

Latent curing agent rau epoxy resins: Qhov no yog nws thawj daim ntawv thov. Nws tseem ruaj khov thaum sib xyaw nrog epoxy resin nyob rau hauv chav tsev kub (nrog lub txee lub neej ntev tshaj li rau lub hlis) tab sis dhau mus sai heev - txuas thiab kho thaum rhuab mus rau 145-180℃; nws yog dav siv nyob rau hauv zus tau tej cov ib tug - cov khoom epoxy adhesives, hmoov txheej, thiab FR-4 tooj liab-clad laminates.
Pharmaceutical thiab tshuaj tua kab nruab nrab: Siv rau hauv kev sib txuas ntawm sulfonamide antibacterials, tshuaj tiv thaiv kab mob (xws li metformin), thiab Vitamin B12; nws kuj yog ib qho tseem ceeb raw khoom rau tshiab neonicotinoid insecticides.
Muaj cov additives: Siv los ua tus neeg sawv cev thaum ntxov rau cov cement, tus neeg sawv cev denitrification hauv steelmaking, roj hmab vulcanization accelerator, ib tug dye fixing agent, thiab nitrogen fertilizer synergist (nitrification inhibitor).
Kev kho dej flocculant: Dicyandiamide-formaldehyde resin ua tau zoo heev decolorizing flocculant rau kev kho cov dej khib nyiab los ntawm textile printing, dyeing, thiab papermaking industries.

Toxicity: Tsawg toxicity. Qhov ncauj LD₅₀ (rat) > 500 mg/kg. Ua phem yog tias nqus tau plua plav los yog nqos; irritating qhov muag thiab tawv nqaij; tej zaum yuav ua rau daim tawv nqaij ua pob khaus.
Hluav taws kub thiab tawg phom sij: Tsis yog -flammable nws tus kheej, tab sis decomposes nyob rau hauv high tshav kub kom tso tawm cov pa phem heev xws li cyanide thiab nitrogen oxides.
Kev khaws cia thiab kev thauj mus los: Khaws rau hauv qhov chaw txias, qhuav, zoo -ventilated warehouse; khaws nruj me ntsis tiv thaiv los ntawm noo noo. Yuav tsum tau muab cais los ntawm cov muaj zog oxidizers, acids, thiab alkalis; tsis txhob khaws cia ua ke. Ua tib zoo saib xyuas thaum thauj khoom thiab tshem tawm kom tsis txhob muaj pob puas.
