Yintoni iDicyandiamide CAS 461-58-5?

I-Dicyandiamide, efinyezwa ngokuthi yi-DICY okanye i-DACD, yi-dimer ye-cyanamide kunye ne-cyano derivative ye-guanidine. Yi-powder emhlophe yekristale. Iyanyibilika emanzini, kwi-alcohol, kwi-ethylene glycol nakwi-dimethylformamide, kwaye ayinyibiliki kwi-ether nakwi-benzene. Ayitshi. Ihlala iqinile xa yomile. I-arhente yokulungisa i-Dicyandiamide yeyeyona arhente yokulungisa ubushushu esetyenziswayo kuqala. Iqinile kubushushu begumbi kwaye ayinyibiliki kwi-epoxy resin. Isasazwa kwi-epoxy resin ngendlela yee-microparticles ize ifudunyezwe ukuze iphendule. Yakuba ifudunyezwe kufutshane nendawo yokunyibilika, iqala ukunyibilika kwaye iphendule ngokukhawuleza ukuze ivuselelwe.

Isicelo

(1) I-Dicyandiamide isetyenziswa njengezinto eziluhlaza kwiityuwa ze-guanidine kunye ne-cyanamide. Iityuwa ezahlukeneyo ze-guanidine zinokuveliswa ngokuphendula i-dicyandiamide kunye ne-asidi. I-Benzene cyanamide efunyenwe ngokuphendula kwe-dicyandiamide kunye ne-benzonitrile yindawo ephakathi yokugquma, ii-laminates, kunye neepowders zokubumba.
(2) I-Dicyandiamide isetyenziswa njengesithako sedayi. I-dicyandiamide resin efunyenwe yi-dicyandiamide kunye ne-formaldehyde ingasetyenziswa njengesithako sedayi.
(3) Izichumisi zeDicyandiamide kunye nezichumisi ezidityanisiweyo zeDicyandiamide zinokulawula umsebenzi weebhaktheriya ezinika i-nitrogen, zilawule izinga lokuguqulwa kwesichumisi se-nitrogen emhlabeni, zinciphise ukulahleka kwe-nitrogen, kwaye ziphucule ukusebenza kakuhle kwesichumisi.
(4) I-Dicyandiamide isetyenziswa njengesixhobo esiphakathi sekhemikhali. Kwizonyango, isetyenziselwa ukulungisa i-guanidine nitrate, amayeza e-sulfonamide, njl.njl.; ikwasetyenziselwa ukulungisa i-thiourea, i-nitrocellulose stabilizer, i-rubber vulcanization accelerator, i-steel surface hardener, i-artificial leather filler, i-adhesive, njl. I-pharmaceutical intermediate 5-azacytosine ingafumaneka ngokuphendula i-dicyandiamide nge-formic acid.
(5) I-Dicyandiamide yokumisela i-cobalt, i-nickel, i-copper kunye ne-palladium, i-organic synthesis, i-nitrocellulose stabilizer, i-hardenener, i-detergent, i-vulcanization accelerator, i-resin synthesis.
