Gịnị bụ Dicyandiamide CAS 461-58-5?

Dicyandiamide, nke a na-akpọ DICY ma ọ bụ DACD, bụ dimer nke cyanamide na ihe e si na guanidine nweta. Ọ bụ ntụ ọcha kristal. Ọ na-agbaze na mmiri, mmanya, ethylene glycol na dimethylformamide, ọ fọrọ nke nta ka ọ ghara ịgbaze na ether na benzene. Ọ naghị agba ọkụ. Ọ na-adịgide mgbe ọ kpọrọ nkụ. Ihe na-agbaze na Dicyandiamide so n'ụdị ihe na-agbaze na-ekpo ọkụ nke e ji mee ihe. Ọ siri ike na okpomọkụ ụlọ ma ọ naghị agbaze na epoxy resin. A na-agbasa ya na epoxy resin n'ụdị microparticles wee kpoo ya ọkụ ka ọ meghachi omume. Ozugbo e kpoo ya ọkụ ruo ebe ọ na-agbaze, ọ na-amalite ịgbaze ma meghachi omume ngwa ngwa iji gwọọ.
