Dicyandiamide CAS 461-58-5 ke eng?

Dicyandiamide, e khutsufalitsoeng e le DICY kapa DACD, ke dimer ea cyanamide le e tsoang ho cyano e tsoang ho guanidine. Ke phofo e tšoeu ea kristale. E qhibiliha metsing, joala, ethylene glycol le dimethylformamide, 'me e batla e sa qhibilihe ka har'a ether le benzene. Ha e chese. E tsitsitse ha e omme. Setsi se phekolang sa Dicyandiamide ke sa mofuta oa khale ka ho fetisisa oa ho phekola mocheso o patehileng o sebelisitsoeng. E tiile mochesong oa kamore 'me ha e qhibilihe ka har'a epoxy resin. E qhalakantsoeng ka epoxy resin ka sebopeho sa microparticles ebe e futhumatsoa ho arabela. Hang ha e cheseha ho fihla haufi le moo ho qhibilihang, e qala ho qhibiliha ebe e sebetsa ka potlako ho fola.
