Dicyandiamide CAS 461-58-5
Dicyandiamide, oo loo soo gaabiyo DICY ama DACD, waa dimer cyanamide ah iyo cyano derivative oo ka soo jeeda guanidine. Waa budo cad oo crystalline ah. Waxay ku milmi kartaa biyaha, khamriga, ethylene glycol iyo dimethylformamide, waxayna ku dhowdahay in lagu milmi karo ether iyo benzene. Ma guban karo. Waa mid deggan marka uu qalalan yahay. Wakiilka daaweynta Dicyandiamide wuxuu ka tirsan yahay nooca ugu horreeya ee wakiilka daaweynta kulaylka ee qarsoon ee la isticmaalo. Waa mid adag heerkulka qolka mana milmi karo resin epoxy. Waxaa lagu kala firdhiyaa resin epoxy qaab microparticles ka dibna waa la kululeeyaa si uu uga falceliyo. Marka la kululeeyo meel u dhow barta dhalaalaysa, waxay bilaabataa inay milmiso oo si degdeg ah uga falceliso si ay u bogsato.

(1) Dicyandiamide waxaa loo isticmaalaa sidii walxo ceeriin ah oo loogu talagalay cusbada guanidine iyo cyanamide. Cusbo kala duwan oo guanidine ah ayaa lagu soo saari karaa iyadoo la falgalo dicyandiamide oo leh aashito. Cyanamide Benzene oo laga helo falgalka dicyandiamide iyo benzonitrile waa dhexdhexaad u ah dahaarka, laminates-ka, iyo budada qaabaynta.
(2) Dicyandiamide waxaa loo isticmaalaa sidii rinjiyeyn. Dicyandiamide resin-ka laga helo falgalka dicyandiamide iyo formaldehyde waxaa loo isticmaali karaa sidii rinjiyeyn.
(3) Bacriminta Dicyandiamide iyo Bacriminta isku-dhafka ah ee dicyandiamide waxay xakameyn karaan dhaqdhaqaaqa bakteeriyada nitrifying, waxay nidaamin karaan heerka beddelka bacriminta nitrogen ee ciidda, waxay yareyn karaan luminta nitrogen, waxayna hagaajin karaan hufnaanta isticmaalka bacriminta.
(4) Dicyandiamide waxaa loo isticmaalaa dhexdhexaad kiimiko oo fiican. Daawada, waxaa loo isticmaalaa in lagu diyaariyo nitrate guanidine, daawooyinka sulfonamide, iwm.; waxaa sidoo kale loo isticmaalaa in lagu diyaariyo thiourea, xasiliyaha nitrocellulose, dardar-geliyaha vulcanization ee caagga ah, adkeyaha dusha sare ee birta, buuxinta maqaarka macmalka ah, dhejiska, iwm. Daawada dhexdhexaadka ah ee 5-azacytosine waxaa lagu heli karaa iyadoo la falgalo dicyandiamide oo leh aashitada formic.
(5) Dicyandiamide si loo go'aamiyo kobalt, nikkel, naxaas iyo palladium, isku-darka dabiiciga ah, xasiliyaha nitrocellulose, adkeeyaha, saabuunta, dardar-gelinta vulcanization, isku-darka resin.
