Microcrystalline Cellulose (MCC) | 9004-34-6
Whakaahuatanga Hua
Ko te microcrystalline cellulose he kupu mo te penupenu rakau parakore, ka whakamahia hei kakano, hei kakano, hei whakakapi mo te ngako, hei whakakorikori, hei whakaroa, me te kaikawe i roto i te hanga kai.Ko te ahua tino noa ka whakamahia i roto i nga taapiri huaora ranei. papa. Ka whakamahia ano i roto i nga whakamatautau tohu mo te tatau i nga huaketo, hei rereke ki te carboxymethylcellulose.He maha nga huarahi, ko te cellulose te mea tino pai. He waerau hanga maori, he waeine hukahuka i honoa e te herenga 1-4 beta glycosidic. Ko enei mekameka cellulose raina he paihere kia rite ki te microfibril e hurihuri ana i roto i nga pakitara o te tipu tipu. Ko ia microfibril e whakaatu ana i te tohu teitei o te hononga-a-roto e toru-ahua ka puta mai he hanganga tioata e kore e rewa i roto i te wai me te aukati ki nga reagents. Heoi ano, he waahi ngoikore o te microfibril me te ngoikore o te hononga o roto. Ka kiia enei ko nga rohe amorphous engari he pai ake te kiia ko nga wehenga mai i te microfibril kei roto te hanganga-waahanga kotahi. Ka wehea te rohe tioata hei whakaputa i te cellulose microcrystalline.
