Taupānga:
Ka whakatau i te cobalt, nickel, copper me te palladium.Organic Synthesis.Nitrocellulose stabilizer.Hardener.Detergent.Vulcanization accelerator.Resin synthesis.
Ka whakamahia hei kaikawe rongoa huna mo nga adhesives kapia epoxy.Ko te hanga i tetahi waahanga epoxy adhesives.Ko te rahi o te matūriki o te dicyandiamide he iti iho i te rite ranei ki te 5μm (2500 mesh), ka taea e ia te hanga i te whakatārewatanga i roto i te kapia epoxy kaore he rerenga. Ko te inenga tohutoro ko te 4-12 nga waahanga, a ko te oranga o te 100g epoxy resin hanganga he 6-12 marama. I te wa ko te waahanga o te dicyandiamide he 17 nga waahanga, ko te wa rokiroki he iti iho i te 2 marama. Ina ko te waahanga he 8 nga waahanga, ko te rokiroki. Ka taea te roa ki te haurua o te tau.Curing conditions170℃/lh or 180℃/20min.Heat distortion temperature 125℃.Also used as curing agent for one-compone waterborne epoxy adhesives.The reference dosage is 7 servings.The pūnaha pūhui o te dicyandiamide (5-6 nga waahanga) me te hydrazide (3-4 nga waahanga), Ka taea e ia te rongoa i te kapia epoxy i te 120 ℃ / 45min.
Hei rauemi mata o te tote guanidine me te melamine
Ka taea te whakaputa i nga momo tote guanidine ma te whakahoki i te dicyandiamide me te waikawa.Ko te benzo-substituted melamine diamine i riro mai i te tauhohenga o te dicyandiamide me te benzonitrile he takawaenga mo nga paninga, laminates me nga paura whakarewa.
Ka whakamahia hei kaihoko whakatika tae.
Ka taea te whakamahi i te kapia dicyandiamide i puta mai i te tauhohenga o te dicyandiamide me te formaldehyde hei kaihoko whakatika waikano.
Te tongi Dicyandiamide
Ka taea e te tongi puhui Dicyandiamide te whakahaere i te mahi o te huakita nitrifying.Whakaritea te tere o te huringa tongi hauota i roto i te oneone,Whakaitihia te mate hauota me te whakapai ake i te pai o te whakamahi tongi.
Hei takawaenga matū pai
I roto i te rongoa, ka whakamahia ki te whakaputa i te guanidine nitrate, sulfonamides, me etahi atu..Ka whakamahia ano hoki ki te whakaputa i te tiourea, te nitrocellulose stabilizer, te whakatere vulcanization rapa, te whakamaroke mata rino, te whakakii hiako horihori, te whakapiri, me etahi atu.Ka taea e te takawaenga rongoa 5-azacytosine kia whiwhi i te tauhohenga o te dicyandiamide me te waikawa formic.Nitrogen doping o nga rauemi waro hei puna hauota.
Mōkī:20 kg/50 kg/100 kg ia pp peeke raranga;
25 kg/pepa-kirihou putea hiato mo te tohu hiko.
Tikanga rokiroki
Te rokiroki hiri i te 2 ℃ ~ 8 ℃, te rokiroki i roto i te waahi hau me te maroke, te karo i te pa ki etahi atu waikura.I te wa e kawe ana me te utaina, me tiaki mai i te makuku me te whakahaere ma te tupato.
