Dicyandiamide CAS 461-58-5
Dicyandiamide, mu magambo make DICY cyangwa DACD, ni dimer ya cyanamide n'icyavuye kuri guanidine. Ni ifu y'umweru ikoze mu cyuma. Irashonga mu mazi, alcool, ethylene glycol na dimethylformamide, kandi hafi ya yose ntishonga muri ether na benzene. Ntishobora gushya. Irakomera iyo yumye. Dicyandiamide ikoreshwa mu buryo bwa mbere bwo gushonga bushyuha. Irakomera ku bushyuhe bw'icyumba kandi ntishonga muri epoxy resin. Ikwirakwizwa muri epoxy resin mu buryo bwa microparticles hanyuma igashyuha kugira ngo ikore. Iyo imaze gushyuha hafi y'aho ishongesherezwa, itangira gushonga no gukora vuba kugira ngo ikore.

(1) Dicyandiamide ikoreshwa nk'ibikoresho fatizo byo gukora umunyu wa guanidine na cyanamide. Umunyu utandukanye wa guanidine ushobora gukorwa hakoreshejwe dicyandiamide hamwe na aside. Benzene cyanamide iboneka binyuze mu gukora kwa dicyandiamide na benzonitrile ni igikoresho cyo hagati cyo gusiga, laminates, n'ifu yo gushushanya.
(2) Dicyandiamide ikoreshwa nk'umuti ufata irangi. Resin ya dicyandiamide iboneka binyuze mu gukora kwa dicyandiamide na formaldehyde ishobora gukoreshwa nk'umuti ufata irangi.
(3) Ifumbire mvaruganda ya Dicyandiamide n'ifumbire mvaruganda ya Dicyandiamide ishobora kugenzura imikorere ya bagiteri zitanga nitrifying, ikagenzura umuvuduko w'ihindagurika ry'ifumbire ya azote mu butaka, ikagabanya igihombo cya azote, kandi ikanoza imikorere myiza y'ifumbire.
(4) Dicyandiamide ikoreshwa nk'ikintu cyiza cyo mu rwego rwo hejuru. Mu buvuzi, ikoreshwa mu gutegura nitrate ya guanidine, imiti ya sulfonamide, nibindi; ikoreshwa kandi mu gutegura thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive, nibindi. 5-azacytosine yo mu rwego rwo hejuru mu buvuzi ishobora kuboneka hakoreshejwe dicyandiamide hamwe na aside formic.
(5) Dicyandiamide yo kumenya kobalt, nikeli, umuringa na palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, resin synthesis.
