Dicyandiamide CAS 461-58-5
Dicyandiamide, oo loo soo gaabiyo sida DICY ama DACD, waa dimer of cyanamide iyo cyano derivative of guanidine. Waa budo crystalline cad. Waxay ku milmi kartaa biyaha, khamriga, ethylene glycol iyo dimethylformamide, waxayna ku dhowdahay inaan lagu milmi karin ether iyo benzene. Waa mid aan guban karin. Way xasilloon tahay marka qallalan. Wakiilka daawaynta ee Dicyandiamide waxa iska leh nooca ugu horreeya ee daawaynta kulaylka ee daawaynta qarsoon ee la isticmaalo. Waxay ku adag tahay heerkulka qolka oo aan lagu milmi karin resin epoxy. Waxa lagu kala firdhiyaa xabagta epoxy-ka oo ah qaab unugyo yaryar ah ka dibna la kululeeyo si ay uga falceliso. Marka la kululeeyo meel u dhow barta dhalaalka, waxay bilaabataa inay milaan oo ay si degdeg ah uga falceliso si ay u daweyso.

(1) Dicyandiamide waxa loo isticmaalaa sida walxo ceeriin ah oo loogu talagalay cusbada guanidine iyo cyanamide. Cusbada guanidine ee kala duwan ayaa lagu soo saari karaa iyadoo lagu falcelinayo dicyandiamide oo leh asiidh. Benzene cyanamide oo ay heshay falcelinta dicyandiamide iyo benzonitrile waa dhex dhexaad u ah dahaarka, laminates, iyo budada wax lagu dhejiyo.
(2) Dicyandiamide waxa loo isticmaalaa sida hagaajinta dheeha. Resin-ka dicyandiamide ee laga helo falcelinta dicyandiamide iyo formaldehyde waxa loo isticmaali karaa sidii hagaajinta dheeha.
(3) Bacriminta Dicyandiamide iyo Bacriminta isku dhafka dicyandiamide waxay xakameyn karaan dhaqdhaqaaqa bakteeriyada nitrifying, waxay nidaamiyaan heerka beddelka bacriminta nitrogen ee ciidda, waxay yareeyaan khasaaraha nitrogen, waxayna wanaajiyaan waxtarka isticmaalka bacriminta.
(4) Dicyandiamide waxa loo isticmaalaa dhexdhexaad kiimiko oo wanaagsan. Daawada, waxaa loo isticmaalaa in lagu diyaariyo guanidine nitrate, daawooyinka sulfonamide, iwm.; waxa kale oo loo isticmaalaa in lagu diyaariyo thiourea, nitrocellulose stabilizer, dardar vulcanization caag ah, birta adag ee dusha birta, buuxinta maqaar macmal ah, xabagta, iwm. Dhexda dhexe ee dawooyinka 5-azacytosine waxaa lagu heli karaa by falcelin dicyandiamide leh formic acid.
(5) Dicyandiamide ee go'aaminta cobalt, nikkel, copper iyo palladium, synthesis organic, nitrocellulose stabilizer, hardener, saabuunta, dardargelinta vulcanization, synthesis resin.
