Iyini i-Dicyandiamide CAS 461-58-5?

I-Dicyandiamide, efushanisiwe ngokuthi i-DICY noma i-DACD, iyi-dimer ye-cyanamide kanye nokuphuma kwe-cyano ku-guanidine. Impushana emhlophe ecwebezelayo. Iyancibilika emanzini, utshwala, i-ethylene glycol ne-dimethylformamide, futhi icishe ingancibiliki ku-ether ne-benzene. Ayishi. Iqinile uma yomile. I-ejenti yokwelapha i-Dicyandiamide ingeyohlobo lwakuqala lwe-ejenti yokwelapha efihlekile elapha ukushisa eyasetshenziswa. Iqinile ekamelweni lokushisa futhi ayincibiliki ku-epoxy resin. Ihlakazeka ku-epoxy resin ngendlela yama-microparticles bese iyashiswa ukuze isabele. Uma isishiselwe eduze nendawo encibilikayo, iqala ukuncibilika futhi isabela ngokushesha ukuze yelapheke.

Isicelo

(1) I-Dicyandiamide isetshenziswa njengento eluhlaza kasawoti we-guanidine ne-cyanamide. Usawoti ohlukahlukene we-guanidine ungakhiqizwa ngokuphendula i-dicyandiamide nge-asidi. I-Benzene cyanamide etholwe ukusabela kwe-dicyandiamide ne-benzonitrile iyindawo ephakathi nendawo yokumboza, ama-laminates, nezimpushana zokubumba.
(2) I-Dicyandiamide isetshenziswa njengendlela yokulungisa udayi. I-dicyandiamide resin etholwe ukusabela kwe-dicyandiamide ne-formaldehyde ingasetshenziswa njengendlela yokulungisa udayi.
(3) Umanyolo we-Dicyandiamide nomanyolo ohlanganisa i-dicyandiamide ungalawula ukusebenza kwamagciwane afaka i-nitrifying, ulawule izinga lokuguqulwa kukamanyolo we-nitrogen enhlabathini, unciphise ukulahleka kwe-nitrogen, futhi uthuthukise ukusebenza kahle kokusetshenziswa kukamanyolo.
(4) I-Dicyandiamide isetshenziswa njengamakhemikhali aphakathi nendawo. Emithi, isetshenziselwa ukulungisa i-guanidine nitrate, izidakamizwa ze-sulfonamide, njll.; iphinde isetshenziselwe ukulungisa i-thiourea, i-nitrocellulose stabilizer, i-rubber vulcanization accelerator, i-steel surface hardener, i-artificial leather filler, i-adhesive, njll. I-pharmaceutical intermediate 5-azacytosine ingatholakala ngokuphendula i-dicyandiamide nge-formic acid.
(5) I-Dicyandiamide yokunquma i-cobalt, i-nickel, ithusi ne-palladium, i-organic synthesis, i-nitrocellulose stabilizer, i-hardener, i-detergent, i-vulcanization accelerator, i-resin synthesis.
