Dicyandiamide CAS 461-58-5
Dicyandiamide, e khutsufalitsoeng e le DICY kapa DACD, ke dimer ea cyanamide le motsoako oa cyano oa guanidine. Ke phofo e tšoeu ea kristale. E qhibiliha ka metsing, joala, ethylene glycol le dimethylformamide, 'me e batla e sa qhibilihe ka har'a ether le benzene. Ha e chese. E tsitsitse ha e omme. Moemeli oa Dicyandiamide o phekolang ke oa mofuta oa pele oa moemeli oa ho phekola o patiloeng o sebelisoang. O tiile mochesong oa kamore 'me ha o qhibilihe ka har'a epoxy resin. O hasana ka har'a epoxy resin ka mokhoa oa li-microparticles ebe o futhumatsoa ho arabela. Hang ha e futhumatsoa ho fihlela haufi le ntlha ea ho qhibiliha, e qala ho qhibiliha le ho arabela ka potlako ho fola.

(1) Dicyandiamide e sebediswa e le thepa e tala bakeng sa matswai a guanidine le cyanamide. Matswai a fapaneng a guanidine a ka hlahiswa ka ho kopanya dicyandiamide le asiti. Benzene cyanamide e fumanwang ka karabelo ya dicyandiamide le benzonitrile ke sebaka se mahareng bakeng sa dikobo, dilaminate le phofo ya ho bopa.
(2) Dicyandiamide e sebediswa e le ntho e kopanyang dae. Resin ya dicyandiamide e fumanwang ka lebaka la karabelo ya dicyandiamide le formaldehyde e ka sebediswa e le ntho e kopanyang dae.
(3) Manyolo a Dicyandiamide le manyolo a dicyandiamide a ka laola mosebetsi wa dibaktheria tse nang le nitrifying, a laola sekgahla sa phetoho ya manyolo a naetrojene mobung, a fokotsa tahlehelo ya naetrojene, mme a ntlafatsa bokgoni ba tshebediso ya manyolo.
(4) Dicyandiamide e sebediswa e le sesebediswa se setle sa dikhemikhale. Bongakeng, e sebediswa ho lokisa guanidine nitrate, dithethefatsi tsa sulfonamide, jj.; e boetse e sebediswa ho lokisa thiourea, nitrocellulose stabilizer, rabara vulcanization accelerator, steel surface hardener, maiketsetso a letlalo, sekgomaretsi, jj. 5-azacytosine ya meriana e ka fumanwa ka ho kopanya dicyandiamide le formic acid.
(5) Dicyandiamide bakeng sa ho fumana cobalt, nickel, koporo le palladium, tlhahiso ea lintho tse phelang, stabilizer ea nitrocellulose, hardener, sesepa sa ho hlatsoa, accelerator ea vulcanization, tlhahiso ea resin.
