POLYETHYLENEIMINE CAS 9002-98-6 me NW 600-20000000
Ko tenei hua he wai karekau he tae, he kowhai ranei he wai keokeo teitei.Wairewa i roto i te wai, waiwaro, hygroscopic, insoluble in benzene and acetone.Ka puta te rerenga ina tutaki ki te waikawa pungatara me te uara pH iti iho i te 2.4.He pai te utu o te wairewa wai, a ko te taapiri o te formaldehyde ka puta te toha.Ka whakamahia hei kaihoko kaha maku o te pepa manawa kore rahi, a ko te kaihoko pupuri me te kaihoko patu i roto i te mahi pepa ka taea te whakaiti i te tohu whiu o te penupenu.Whakapai ake i te kaha whakamaoritanga o te pepa.Ko te maroke o te pepa ka piki ake i te 1% - 4%.Ka piki ake te kaha o te whakaputa i te 5% - 20%.
