Dicyandiamide CAS 461-58-5
ʻO Dicyandiamide, i hoʻopau ʻia ʻo DICY a i ʻole DACD, he dimer o ka cyanamide a me kahi cyano derivative o guanidine. He pauda kristal keʻokeʻo. Hiki ke hoʻoheheʻe ʻia i ka wai, ka waiʻona, ka ethylene glycol a me ka dimethylformamide, a aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ether a me benzene. ʻAʻole hiki ke puhi ʻia. Paʻa ke maloʻo. ʻO ka lāʻau lapaʻau ʻo Dicyandiamide no ke ʻano mua loa o ka lāʻau lapaʻau latent hoʻōla wela i hoʻohana ʻia. Paʻa ia ma ka lumi wela a hiki ʻole ke hoʻoheheʻe ʻia i ka resin epoxy. Hoʻopuehu ʻia i loko o ka resin epoxy ma ke ʻano o nā microparticles a laila hoʻomehana ʻia e hana. I ka manawa e wela ai a kokoke i ka helu heheʻe, hoʻomaka ia e hoʻoheheʻe a hana wikiwiki e ho'ōla.

(1) Hoʻohana ʻia ʻo Dicyandiamide ma ke ʻano he mea maka no nā paʻakai guanidine a me ka cyanamide. Hiki ke hana ʻia nā paʻakai guanidine like ʻole ma ka hana ʻana i ka dicyandiamide me ka waikawa. ʻO Benzene cyanamide i loaʻa ma ka hopena o ka dicyandiamide a me benzonitrile he mea waena no ka uhi ʻana, nā laminates, a me nā pauka.
(2) Hoʻohana ʻia ʻo Dicyandiamide ma ke ʻano he fixative dye. Hiki ke hoʻohana ʻia ka resin dicyandiamide e ka hopena o ka dicyandiamide a me formaldehyde e like me ka fixative dye.
(3) Hiki i nā fertilizers dicyandiamide a me nā mea hoʻohuihui dicyandiamide ke hoʻomalu i ka hana o ka nitrifying bacteria, hoʻoponopono i ka hoʻololi ʻana o ka fertilizer nitrogen i loko o ka lepo, hoʻemi i ka nalowale o ka nitrogen, a hoʻomaikaʻi i ka pono o ka hoʻohana ʻana i ka fertilizer.
(4) Hoʻohana ʻia ʻo Dicyandiamide ma ke ʻano he waena kemika maikaʻi. I ka lāʻau lapaʻau, hoʻohana ʻia e hoʻomākaukau i ka guanidine nitrate, nā lāʻau sulfonamide, etc.; hoʻohana ʻia ia e hoʻomākaukau i ka thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive, etc. Hiki ke loaʻa ka pharmaceutical intermediate 5-azacytosine ma ka reacting dicyandiamide me formic acid.
(5) Dicyandiamide no ka hoʻoholoʻana i ka cobalt, nickel, copper and palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, resin synthesis.
