Cellulose ea Microcrystalline (MCC) | 9004-34-6
Tlhaloso ea Lihlahisoa
Microcrystalline cellulose ke lentsoe bakeng sa pulp ea lehong e hloekisitsoeng 'me e sebelisoa e le texturizer, anti-caking agent, sebaka sa mafura, emulsifier, extender, le agent e ngata tlhahisong ea lijo. matlapa. E boetse e sebelisoa litlhahlobong tsa plaque bakeng sa ho bala likokoana-hloko, e le mokhoa o mong oa carboxymethylcellulose.Ka litsela tse ngata, cellulose e etsa excipient e loketseng. Polima ea tlhaho, e entsoe ka likarolo tsa tsoekere tse hokahantsoeng ke 1-4 beta glycosidic bond. Liketane tsena tsa linear cellulose li kopantsoe hammoho joalo ka microfibril e kopantsoeng hammoho maboteng a sele ea semela. E 'ngoe le e' ngoe ea microfibril e bonts'a tekanyo e phahameng ea tlamahano e ka hare ea mahlakore a mararo e hlahisang sebopeho sa kristale se ke keng sa qhibiliha ka metsing 'me se hanyetsana le li-reagents. Leha ho le joalo, ho na le likarolo tse fokolang tsa microfibril tse nang le maqhama a fokolang a ka hare. Tsena li bitsoa libaka tsa amorphous empa ka nepo li bitsoa dislocation ho tloha ha microfibril e na le sebopeho sa karolo e le 'ngoe. Sebaka sa crystalline se arotsoe ho hlahisa cellulose ea microcrystalline.
