Whakaahuatanga Poto:

Dicyandiamide

Te paura tioata ma.Ko te whakarewatanga i roto i te wai ko te 2.26% i te 13°C,Ko te whakarewatanga teitei i roto i te wai wera.I te wa ka whakapohehehia te wairewa wai i te 80 °C, ka puta te hau haukini. Ina te whakarewatanga i roto i te waiwaro tino (C2H5OH) me te etera he 13 °C,he 1.26% me te 0.01%.Ka whakarewahia i roto i te haukini wai, te wai wera, te waiwaro, te acetone hydrate, te dimethylformamide, te kore e rewa i roto i te etera, e kore e rewa i roto i te benzene me te chloroform.Te kiato whanaunga (d254) 1.40.Ira whakarewa 209.5 ℃.Pumau ina maroke.Kaore e wera.He iti te paitini, te horopeta whakamate (kiore, waha)>4000mg/kg.Ko te 5mg/m³ te kukū mōrahi e whakaaetia ana ki te hau.

Taupānga:

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.

Dicyandiamideka taea te whakamahi i te kapia i puta mai i te tauhohenga o te dicyandiamide me te formaldehyde hei kaihoko whakatika waikano.

Te tongi Dicyandiamide

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.
Kiia i roto i te peeke raranga me te peeke kirihou o roto, e 5 nga paparanga peeke pepa kraft kikii.Me hiri te waha o te peeke kia kaua e turuturu.Ko te taumaha kupenga 25±0.2kg mo ia peeke.
