Dicyandiamide CAS 461-58-5
Dicyandiamide, mu magambo ahinnye yitwa DICY cyangwa DACD, ni dimer ya cyanamide hamwe na cyano ikomoka kuri guanidine. Nifu ya kirisiti yera. Irashobora gushonga mumazi, inzoga, Ethylene glycol na dimethylformamide, kandi hafi yo kudashonga muri ether na benzene. Ntabwo ari umuriro. Irahagarara iyo yumutse. Umuti wo gukiza Dicyandiamide ni mubwoko bwambere bwubushyuhe bukiza bwihishwa bukoreshwa. Irakomeye mubushyuhe bwicyumba kandi ntigishobora gukomera muri epoxy resin. Ikwirakwizwa muri epoxy resin muburyo bwa microparticles hanyuma igashyuha kugirango ikore. Iyo bimaze gushyuha hafi yo gushonga, bitangira gushonga no kubyakira vuba kugirango bikire.

(1) Dicyandiamide ikoreshwa nkibikoresho fatizo byumunyu wa guanidine na cyanamide. Umunyu utandukanye wa guanidine urashobora kubyara mugukora dicyandiamide hamwe na aside. Benzene cyanamide yabonetse kubisubizo bya dicyandiamide na benzonitrile ni intera yo gutwikira, laminates, hamwe nifu ya poro.
(2) Dicyandiamide ikoreshwa nkigikorwa cyo gusiga irangi. Dicyandiamide resin yabonetse kubisubizo bya dicyandiamide na formaldehyde irashobora gukoreshwa mugukosora irangi.

(4) Dicyandiamide ikoreshwa nkimiti myiza yimiti. Mubuvuzi, ikoreshwa mugutegura nitrat ya guanidine, imiti ya sulfonamide, nibindi.; ikoreshwa kandi mugutegura thiourea, stabilisateur ya nitrocellulose, yihuta ya reberi, reba ibyuma byangiza, ibyuma byuzuza uruhu, ibifata, nibindi.
