Yintoni i-Dicyandiamide CAS 461-58-5?

I-Dicyandiamide, efinyeziweyo njenge-DICY okanye i-DACD, yi-dimer ye-cyanamide kunye ne-cyano ephuma kwi-guanidine. Ingumgubo omhlophe wekristale. Iyanyibilika emanzini, utywala, i-ethylene glycol kunye ne-dimethylformamide, kwaye iphantse inganyibiliki kwi-ether kunye ne-benzene. Ayinakutsha. Iyazinza xa yomile. I-arhente yokunyanga i-Dicyandiamide yolona hlobo lwakuqala lwe-ejenti yokunyanga ubushushu esele isetyenzisiwe. Iqinile kwiqondo lokushisa kwaye ayinyibiliki kwi-epoxy resin. Isasazwa kwi-epoxy resin ngendlela ye-microparticles kwaye emva koko ishushu ukuze iphendule. Yakuba ishushu ukuya kufutshane nendawo yokunyibilika, iqala ukunyibilika kwaye isabele ngokukhawuleza ukuze inyangwe.

Isicelo

(1) IDicyandiamide isetyenziswa njengento ekrwada yetyuwa yeguanidine necyanamide. Iityuwa ezahlukeneyo ze-guanidine zinokuveliswa ngokusabela i-dicyandiamide ngeasidi. I-Benzene cyanamide efunyenwe ngokusabela kwe-dicyandiamide kunye ne-benzonitrile yindawo ephakathi yokwaleka, i-laminates, kunye nomgubo wokubumba.
(2) IDicyandiamide isetyenziswa njengento yokulungisa idayi. I-dicandiamide resin efunyenwe ngokusabela kwe-dicyandiamide kunye ne-formaldehyde ingasetyenziswa njengento yokulungisa idayi.
(3) Izichumisi zeDicyandiamide nezichumiso ezixutywe ne<em>dicyandiamide ziyakwazi ukulawula ukusebenza kweebhaktheriya ezivelisa i<em>nitrifying, zilawule umlinganiselo wokuguqulwa kwesichumiso senitrogen emhlabeni, zinciphise ilahleko yenitrogen, yaye ziphucule ukusebenza kakuhle kokusetyenziswa kwesichumiso.
(4) IDicyandiamide isetyenziswa njengekhemikhali ephakathi. Kwiyeza, isetyenziselwa ukulungiselela i-nitrate ye-guanidine, iziyobisi ze-sulfonamide, njl.; iphinda isetyenziswe ekulungiseleleni i-thiourea, i-nitrocellulose stabilizer, i-rubber vulcanization accelerator, i-hardener surface yensimbi, i-filler yesikhumba eyenziweyo, i-adhesive, njl njl.
(5) I-Dicyandiamide yokumisela i-cobalt, i-nickel, ithusi kunye ne-palladium, i-organic synthesis, i-nitrocellulose stabilizer, i-hardener, i-detergent, i-vulcanization accelerator, i-resin synthesis.
