Melemo ea cellulose ke efe?

Cellulose ke mofuta oa selulose eo tlhahiso le tšebeliso ea eona e tla eketseha ka potlako. Ke cellulose e sa tsoakoang e entsoeng ka k'hothone e hloekisitsoeng ka mor'a ho bola, e sebelisa propylene oxide le methyl chloride e le li-etherification agents, le ka letoto la liketso. Tekanyo ea ho nka sebaka ka kakaretso ke 1.2 ~ 2.0. Litšobotsi tsa eona li fapane ka lebaka la likarolo tse fapaneng tsa likarolo tsa tert-butyl le likarolo tsa hydroxypropyl.

(1) Cellulose e qhibiliha ka metsing a batang, 'me ho tla ba thata ho qhibiliha ka metsing a belang. Empa mocheso oa eona oa gelatinization metsing a belang o phahame haholo ho feta oa carboxycellulose. Boemo ba ho qhibiliha metsing a batang le bona bo ntlafetse haholo ha bo bapisoa le carboxycellulose.

(2) The viscosity ea cellulose e amana le boholo ba boima ba molek'hule, 'me ha boima ba limolek'hule bo le boholo, ho ba le viscosity e phahameng. Mocheso o tla boela o ama viscosity ea oona, mocheso oa phahama, viscosity e fokotseha. Empa viscosity ea eona e phahameng le mocheso o phahameng ha li kotsi ho feta carboxycellulose. Tharollo ea eona ea metsi e tsitsitse ha e bolokiloe mocheso oa kamore.

(3) Ho boloka metsi le ho qhibiliha ha selulose ho itšetlehile ka palo ea eona ea tlatsetso, viscosity, joalo-joalo, 'me tekanyo ea eona ea ho boloka metsi tlas'a tekanyo e lekanang ea ho eketsa e phahame ho feta ea carboxycellulose.

(4) Cellulose e hanyetsana le asiti le alkali, 'me tharollo ea eona e tsitsitse haholo ka mefuta ea pH = 2 ~ 12. Anhydrous aluminium chloride le lime slurry ha li na tšusumetso e kholo ho thepa ea eona, empa alkali e ka potlakisa sekhahla sa ho qhibiliha le ho ntlafatsa viscosity ea eona. Cellulose e ka tšeptjoa ho matsoai a tloaelehileng a acid, empa ha motsoako oa motsoako oa letsoai o phahame, ponahalo ea motsoako oa selulose e atisa ho eketseha.

(5) Cellulose e ka sebelisoa ka li-polymers tse qhibilihang ka metsing ho etsa mokelikeli o lekaneng le o phahameng oa viscosity aqueous. Joalo ka emulsion ea acrylic, tapioca starch ether, sekhomaretsi sa meroho, jj.

(6) Cellulose e na le khanyetso e matla ea enzyme ho feta carboxycellulose, 'me tharollo ea eona ea metsi ha e na monyetla oa ho qhibiliha ke li-enzyme ho feta carboxycellulose.

(7) Ho khomarela ha cellulose mohahong oa seretse sa samente ho phahame ho feta carboxycellulose.
