Chii chinonzi Dicyandiamide CAS 461-58-5?

Dicyandiamide, rakadimburirwa seDICY kana DACD, idimer yecyanamide uye cyano inotorwa kubva kuguanidine. Icho chichena checrystalline powder. Inonyungudika mumvura, doro, ethylene glycol uye dimethylformamide, uye inenge isinganyunguriki muether nebenzene. Haibatiki. Inogadzikana kana yakaoma. Dicyandiamide kurapa mumiririri ndeyekutanga mhando yekupisa-inorapa latent kurapa agent yakashandiswa. Iyo yakasimba pakupisa kwekamuri uye isinganyunguriki mu epoxy resin. Inoparadzirwa mu epoxy resin muchimiro che microparticles uye yobva yapiswa kuti iite. Kana yapisa kusvika pedyo nekunyungudika, inotanga kunyungudika uye kuita nekukurumidza kuti irapwe.

Application

(1) Dicyandiamide inoshandiswa seyakabikwa mumunyu we guanidine uye cyanamide. Yakasiyana-siyana guanidine munyu inogona kugadzirwa nekuita dicyandiamide neasidhi. Benzene cyanamide inowanikwa nekuita kwedicyandiamide uye benzonitrile ndeyepakati pemachira, laminates, uye upfu hwekuumbwa.
(2) Dicyandiamide inoshandiswa sekugadzirisa dhayi. Iyo dicyandiamide resin inowanikwa nekuita kwedicyandiamide uye formaldehyde inogona kushandiswa sekugadzirisa dhayi.
(3) Mafetereza eDicyandiamide nemafetireza e<em>dicyandiamide anogona kudzora kushanda kweutachiona hwe<em>nitrifying, kudzora kushanduka kwefetireza ye<em>nitrogen muvhu, kuderedza kurasikirwa ne<em>nitrogen, uye kunatsiridza kushanda zvakanaka kwokushandisa fetereza.
(4) Dicyandiamide inoshandiswa sekemikari yakanaka yepakati. Mukurapa, inoshandiswa kugadzirira guanidine nitrate, sulfonamide zvinodhaka, nezvimwewo; inoshandiswawo kugadzirira thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, iron surface hardener, artificial leather filler, adhesive, etc. Mushonga wepakati pemishonga 5-azacytosine inogona kuwanikwa kuburikidza nekuita dicyandiamide nefomic acid.
(5) Dicyandiamide yekutsunga kwecobalt, nickel, mhangura uye palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, resin synthesis.
