Dicyandiamide CAS 461-58-5
Dicyandiamide, luv ua DICY lossis DACD, yog ib qho dimer ntawm cyanamide thiab ib qho cyano derivative ntawm guanidine. Nws yog ib qho hmoov dawb crystalline. Nws yaj tau hauv dej, cawv, ethylene glycol thiab dimethylformamide, thiab yuav luag tsis yaj hauv ether thiab benzene. Nws tsis yog-flammable. Nws ruaj khov thaum qhuav. Dicyandiamide curing agent yog ib qho ntawm cov khoom siv kho cua sov latent curing agent siv thaum ntxov tshaj plaws. Nws yog khov kho ntawm chav tsev kub thiab tsis yaj hauv epoxy resin. Nws yog dispersed hauv epoxy resin hauv daim ntawv ntawm microparticles thiab tom qab ntawd cua sov kom ua rau muaj kev cuam tshuam. Thaum cua sov mus txog ze rau qhov melting point, nws pib yaj thiab teb sai sai kom kho.

(1) Dicyandiamide yog siv ua cov khoom siv raw rau cov ntsev guanidine thiab cyanamide. Ntau yam ntsev guanidine tuaj yeem tsim los ntawm kev sib xyaw dicyandiamide nrog acid. Benzene cyanamide tau los ntawm kev sib xyaw ntawm dicyandiamide thiab benzonitrile yog ib qho nruab nrab rau cov txheej, laminates, thiab molding hmoov.
(2) Dicyandiamide yog siv los ua cov xim pleev xim. Cov dicyandiamide resin tau los ntawm cov tshuaj tiv thaiv ntawm dicyandiamide thiab formaldehyde tuaj yeem siv los ua cov xim pleev xim.
(3) Cov chiv Dicyandiamide thiab cov chiv dicyandiamide tuaj yeem tswj cov haujlwm ntawm cov kab mob nitrifying, tswj cov nqi hloov pauv ntawm cov chiv nitrogen hauv av, txo cov nitrogen poob, thiab txhim kho kev ua haujlwm ntawm kev siv chiv.
(4) Dicyandiamide yog siv ua cov tshuaj nruab nrab zoo. Hauv kev kho mob, nws yog siv los npaj guanidine nitrate, sulfonamide tshuaj, thiab lwm yam; nws kuj yog siv los npaj thiourea, nitrocellulose stabilizer, roj hmab vulcanization accelerator, steel surface hardener, tawv tawv cuav filler, nplaum, thiab lwm yam. Cov tshuaj nruab nrab 5-azacytosine tuaj yeem tau txais los ntawm kev cuam tshuam dicyandiamide nrog formic acid.
(5) Dicyandiamide rau kev txiav txim siab ntawm cobalt, nickel, tooj liab thiab palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, resin synthesis.
