Tikanga Whakaputa

Ko te cellulose miro parakore ka tukuna ki te reitia i te 35-40°C mo te hawhe haora, ka kohia, ka pakaruhia te cellulose, ka tika te pakeke ki te 35°C, kia whiwhi ai te muka alkali tohu toharite o te polymerization i roto i te awhe e hiahiatia ana.Kuhua te muka kawakore ki roto i te ketere whakamaarama, taapirihia te propylene oxide me te methyl chloride, ka whakamaarama i te 50-80 ℃ mo te 5h, ko te pehanga teitei kei te 1.8MPa.Kātahi ka tāpirihia te nui o te waikawa pūmāota me te waikawa oxalic hei horoi i ngā rawa ki te wai wera i te 90°C hei whakanui ake i te rōrahi.Whakakore wai ki te centrifuge.Horoi kia noho kore.Ina he iti iho i te 60% te nui o te wai i roto i te rauemi, whakamaroke ki te rere o te hau wera i te 130 ℃ ki te iti iho i te 5%.Ka mutu, ka tukitukia e te tatari 20 mata kia whiwhi ai i te hua kua oti.
