I-Dicyandiamide CAS 461-58-5
I-Dicyandiamide, efushaniswe ngokuthi i-DICY noma i-DACD, iyi-dimer ye-cyanamide kanye ne-cyano derivative ye-guanidine. Iyimpuphu emhlophe ekristalu. Iyancibilika emanzini, utshwala, i-ethylene glycol kanye ne-dimethylformamide, futhi cishe ayincibiliki ku-ether kanye ne-benzene. Ayishisi. Ihlala isikhathi eside uma yomile. I-Dicyandiamide curing agent ingeyohlobo lokuqala lwe-heat-curing agent esetshenziswayo. Iqinile ekushiseni kwegumbi futhi ayincibiliki ku-epoxy resin. Ihlakazeka ku-epoxy resin ngesimo sezinhlayiya ezincane bese ishiswa ukuze isabele. Uma isishisiwe eduze nendawo yokuncibilika, iqala ukuncibilika futhi isabele ngokushesha ukuze iphole.

(1) I-Dicyandiamide isetshenziswa njengezinto zokusetshenziswa kosawoti we-guanidine kanye ne-cyanamide. Usawoti we-guanidine ohlukahlukene ungakhiqizwa ngokuxuba i-dicyandiamide ne-asidi. I-Benzene cyanamide etholakala ngokusabela kwe-dicyandiamide kanye ne-benzonitrile iyindlela ephakathi yokumboza, ama-laminate, kanye ne-molding powders.
(2) I-Dicyandiamide isetshenziswa njengesithako sodayi. I-dicyandiamide resin etholakala ngokusabela kwe-dicyandiamide kanye ne-formaldehyde ingasetshenziswa njengesithako sodayi.
(3) Umanyolo we-dicyandiamide kanye nomanyolo we-dicyandiamide ohlanganisiwe ungalawula umsebenzi wamagciwane anika i-nitrogen, ulawule izinga lokuguqulwa komanyolo we-nitrogen enhlabathini, unciphise ukulahlekelwa yi-nitrogen, futhi uthuthukise ukusebenza kahle kokusetshenziswa komanyolo.
(4) I-Dicyandiamide isetshenziswa njenge-intermediate enhle yamakhemikhali. Kwezokwelapha, isetshenziselwa ukulungisa i-guanidine nitrate, izidakamizwa ze-sulfonamide, njll.; isetshenziselwa futhi ukulungisa i-thiourea, i-nitrocellulose stabilizer, i-raber 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 kanye ne-palladium, ukwakheka kwezinto eziphilayo, i-nitrocellulose stabilizer, i-hardener, insipho yokuhlanzisisa, i-vulcanization accelerator, ukwakheka kwe-resin.
