Chii chinonzi Dicyandiamide CAS 461-58-5?

Dicyandiamide, kana kuti DICY kana DACD, idimer yecyanamide uye guanidine inobva kucyano. Iupfu hwe crystalline chena. Inonyungudika mumvura, doro, ethylene glycol uye dimethylformamide, uye hainyungudike mu ether ne benzene. Haibatike. Inogara kwenguva refu kana yaoma. Dicyandiamide curing agent ndeyemhando yekutanga ye heat-curing latent curing agent inoshandiswa. Yakasimba patembiricha yemumba uye hainyungudike mu epoxy resin. Inoparadzirwa mu epoxy resin muchimiro chema microparticles uye yozopiswa kuti iite reactive. Kana yapiswa kusvika padyo nenzvimbo yekunyungudika, inotanga kunyungudika uye inopindura nekukurumidza kuti iite reactive.

Kushandiswa

(1) Dicyandiamide inoshandiswa sezvinhu zvisina kugadzirwa zvemunyu weguanidine necyanamide. Munyu wakasiyana-siyana weguanidine unogona kugadzirwa nekuita dicyandiamide neacid. Benzene cyanamide inowanikwa nekuita kwe dicyandiamide ne benzonitrile inhengo yepakati ye coatings, laminates, uye molding powders.
(2) Dicyandiamide inoshandiswa semushonga wedhayi. Dicyandiamide resin inowanikwa nekuita kwe dicyandiamide ne formaldehyde inogona kushandiswa semushonga wedhayi.
(3) Mafetereza eDicyandiamide nemafetereza eDicyandiamide anogona kudzora mashandiro emabhakitiriya anoisa nitrifying, kudzora mwero wekuchinja kwefetereza yenitrogen muvhu, kuderedza kurasikirwa nenitrogen, uye kuvandudza kushanda zvakanaka kwefetereza.
(4) Dicyandiamide inoshandiswa semushonga wemakemikari wakanaka. Mukurapa, inoshandiswa kugadzira guanidine nitrate, sulfonamide drugs, nezvimwewo; inoshandiswawo kugadzira thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive, nezvimwewo. 5-azacytosine inoshandiswa mumishonga inogona kuwanikwa nekushandisa dicyandiamide ne formic acid.
(5) Dicyandiamide yekuona cobalt, nickel, copper uye palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, resin synthesis.
