Dicyandiamide CAS 461-58-5
Dicyandiamide, yomwe chidule chake ndi DICY kapena DACD, ndi dimer ya cyanamide ndi guanidine yomwe imachokera ku cyano. Ndi ufa woyera wa kristalo. Umasungunuka m'madzi, mowa, ethylene glycol ndi dimethylformamide, ndipo susungunuka kwambiri mu ether ndi benzene. Siwoyaka. Umakhala wokhazikika ukauma. Dicyandiamide ndi imodzi mwa mankhwala oyamba ochiritsa kutentha omwe amagwiritsidwa ntchito. Ndi olimba kutentha kwa chipinda ndipo sasungunuka mu epoxy resin. Umafalikira mu epoxy resin mu mawonekedwe a tinthu tating'onoting'ono kenako umatenthedwa kuti uchitepo kanthu. Ukatenthedwa kufika pafupi ndi malo osungunuka, umayamba kusungunuka ndikuchitapo kanthu mwachangu kuti uchiritsidwe.

(1) Dicyandiamide imagwiritsidwa ntchito ngati zinthu zopangira mchere wa guanidine ndi cyanamide. Mchere wosiyanasiyana wa guanidine ukhoza kupangidwa pochita dicyandiamide ndi asidi. Benzene cyanamide yomwe imapezeka pochita dicyandiamide ndi benzonitrile ndi yothandiza kwambiri popanga zokutira, ma laminate, ndi ufa woumba.
(2) Dicyandiamide imagwiritsidwa ntchito ngati chopangira utoto. Utomoni wa dicyandiamide womwe umapezeka chifukwa cha dicyandiamide ndi formaldehyde ungagwiritsidwe ntchito ngati chopangira utoto.
(3) Manyowa a Dicyandiamide ndi manyowa a dicyandiamide amatha kulamulira momwe mabakiteriya amagwirira ntchito, kuwongolera kuchuluka kwa feteleza wa nayitrogeni m'nthaka, kuchepetsa kutayika kwa nayitrogeni, komanso kukonza momwe feteleza amagwiritsidwira ntchito bwino.
(4) Dicyandiamide imagwiritsidwa ntchito ngati mankhwala abwino. Mu mankhwala, imagwiritsidwa ntchito popanga guanidine nitrate, mankhwala a sulfonamide, ndi zina zotero; imagwiritsidwanso ntchito popanga thiourea, nitrocellulose stabilizer, rabara vulcanization accelerator, chitsulo cholimba pamwamba, chodzaza chikopa chopangidwa, zomatira, ndi zina zotero. 5-azacytosine yapakati ya mankhwala ingapezeke mwa kuphatikiza dicyandiamide ndi formic acid.
(5) Dicyandiamide yodziwira cobalt, nickel, copper ndi palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, resin synthesis.
