Cellulose, e leng motsoako o mongata ka ho fetisisa oa lintho tse phelang Lefatšeng, e na le thepa e tsotehang, e 'ngoe ea eona ke bokhoni ba eona ba ho monya metsi.Mofuta ona oa hygroscopic oa cellulose o sebelisoa haholo liindastering tse fapaneng, ho tloha ho masela ho isa ho tsa meriana.Ho utloisisa mekhoa ea ho monya metsi a cellulose ho bohlokoa bakeng sa ho ntlafatsa ts'ebeliso ea eona lits'ebetsong tse fapaneng.
Selelekela:
Cellulose, polysaccharide e entsoeng ka liyuniti tsa tsoekere tse hokahantsoeng ke β(1→4) glycosidic bond, ke karolo ea mantlha ea sebopeho sa mabota a lisele tsa semela.Nala ea tlhaho ea eona, e nchafalitsoeng, le ho senyeha ha eona ho etsa hore e be ntho e lakatsehang haholo lits'ebetsong tse ngata tsa indasteri.E 'ngoe ea litšobotsi tse khahlang tsa cellulose ke bokhoni ba eona ba ho monya metsi hantle.Tšobotsi ena e na le litlamorao tse kholo mafapheng a fapaneng joalo ka masela, ho etsa pampiri, lijo, meriana le biomaterials.Ho utloisisa mekhoa e ipapisitseng le boits'oaro ba cellulose ea ho monya metsi ho bohlokoa bakeng sa ho sebelisa bokhoni ba eona ka botlalo lits'ebetsong tsena.
Lintlha tse susumetsang ho monya ha Metsi ka Cellulose:
Lintlha tse 'maloa li susumetsa matla a ho monya ha cellulose metsing:
Crystallinity: Sebopeho sa kristale sa cellulose se ama haholo thepa ea eona ea ho monya metsi.Libaka tsa Crystalline li bonts'a ho monya ha metsi ho tlase ha ho bapisoa le libaka tsa amorphous ka lebaka la phihlello e thibetsoeng ea limolek'hule tsa metsi.
Sebaka sa Bokaholimo: Karolo e kaholimo ea likhoele tsa cellulose e bapala karolo ea bohlokoa ho monyeng ha metsi.Selulose e arohaneng hantle e nang le sebaka se phahameng se na le tšekamelo ea ho monya metsi a mangata ha ho bapisoa le meaho ea selulose ea bulkier.
Hydrophilicity: Lihlopha tsa Hydroxyl (-OH) tse teng ka har'a limolek'hule tsa cellulose li etsa hore e be hydrophilic, e nolofalletsang ho monya ha metsi ka ho kopanya haedrojene.
Degree of Polymerization: Cellulose e nang le polymerization e phahameng e atisa ho ba le matla a phahameng a ho monya metsi ka lebaka la boteng ba lihlopha tse ngata tsa hydroxyl ka boima ba yuniti.
Thempereichara le Mongobo o Batlang: Maemo a tikoloho joalo ka mocheso le mongobo o lekanyelitsoeng a susumetsa haholo boitšoaro ba cellulose ba ho monya metsi.Lithempereichara tse phahameng le maemo a mongobo ka kakaretso li ntlafatsa ho monya ha metsi ka lebaka la ho eketseha ha limolek'hule tsa metsi.
Mekhoa ea ho khetholla:
Mekhoa e fapaneng e sebelisoa ho khetholla thepa ea ho monya metsi ea cellulose:
Gravimetric Analysis: Mekhoa ea Gravimetric e kenyelletsa ho lekanya phaello ea boima ba lisampole tsa cellulose ha u pepesehela metsi ka nako.Sena se fana ka lintlha tse ngata mabapi le kinetics ea ho monyela ha metsi le mongobo o lekanang.
Fourier Transform Infrared Spectroscopy (FTIR): FTIR spectroscopy e sebelisoa ho sekaseka liphetoho lihlopheng tse sebetsang tsa cellulose ha li monya metsi.Liphetoho tsa maemo a holimo le matla a tsona li bonts'a likamano lipakeng tsa selulose le limolek'hule tsa metsi.
X-ray Diffraction (XRD): XRD e sebelisoa ho lekola liphetoho tsa kristale ea cellulose ka mor'a ho monngoa ha metsi.Ho fokotseha ha index ea crystallinity ho fana ka maikutlo a ho ruruha ha likhoele tsa cellulose ka lebaka la ho monya metsi.
Scanning Electron Microscopy (SEM): SEM e lumella pono ea liphetoho tsa morphological ka har'a likhoele tsa cellulose pele le ka mor'a ho monya ha metsi.E fana ka leseli mabapi le botšepehi ba sebopeho le porosity ea lisebelisoa tsa cellulose.
Lisebelisoa tsa Cellulose joalo ka Hygroscopic Material:
Sebopeho sa hygroscopic sa cellulose se fumana lits'ebetso tse fapaneng liindastering tse fapaneng:
Masela: Likhoele tse entsoeng ka selulose tse kang k'hothone le rayon li sebelisoa haholo ha ho etsoa masela ka lebaka la bokhoni ba tsona ba ho monya mongobo, ho fana ka matšeliso le phefumoloho ea liaparo.
Ho etsa lipampiri: Lithaele tsa cellulose li sebetsa e le thepa e ka sehloohong e tala tlhahisong ea pampiri.Lintho tsa bona tsa ho monya metsi li susumetsa boleng ba pampiri, ho hatisoa le matla.
Indasteri ea Lijo: Lintho tse tsoang ho cellulose tse kang methylcellulose le carboxymethylcellulose li sebelisoa e le li-thiening agents, stabilizers le emulsifiers lihlahisoa tsa lijo.Bokhoni ba bona ba ho monya metsi bo matlafatsa sebopeho le botsitso ba bophelo ba sethala.
Meriana ea Meriana: Li-excipient tse thehiloeng ho cellulose li atisa ho sebelisoa mefuteng ea meriana bakeng sa bokhoni ba tsona ba ho laola ho lokolloa ha lithethefatsi, ho ntlafatsa botsitso, le ho matlafatsa bioavailability.Li boetse li thusa ho arola le ho qhala matlapa le li-capsules.
Lintho tsa Bohlokoa: Li-cellulose hydrogel le lifilimi li ntse li hlaha e le lisebelisoa tse tšepisang tsa biomedical bakeng sa lits'ebetso tse fapaneng tsa biomedical, ho kenyeletsoa phepelo ea lithethefatsi, boenjiniere ba lisele le pholiso ea maqeba.Matla a bona a phahameng a ho monya metsi a etsa hore ho be le hydration e nepahetseng le ho ata ha lisele.
Bokhoni bo tsotehang ba cellulose ba ho monya metsi bo bakoa ke sebopeho sa eona se ikhethang le lik'hemik'hale.Ho utloisisa lintlha tse susumetsang ho monya ha metsi, mekhoa ea sebopeho, le ts'ebeliso ea selulose joalo ka thepa ea hygroscopic ho bohlokoa bakeng sa ho ntlafatsa ts'ebeliso ea eona liindastering tse fapaneng.Patlisiso e tsoelang pele lefapheng lena e tla tsoela pele ho holisa mefuta e mengata ea lits'ebetso le ho kenya letsoho ntlafatsong ea lisebelisoa tse tšoarellang tse nang le thepa e ntlafalitsoeng ea ts'ebetso.
