Ho na le mefuta e 'maloa ea cellulose,' me liphapang tsa tšebeliso ea tsona ke life?

Cellulose ke polymer ea tlhaho e feto-fetohang le e ngata e fumanehang maboteng a lisele tsa limela, e fanang ka tšehetso ea sebopeho le ho tiea. E entsoe ka li-unit tsa tsoekere tse hokahantsoeng hammoho ka li-bond tsa β-1,4-glycosidic. Le ha cellulose ka boeona e le ntho e ts'oanang, tsela eo e hlophisitsoeng le ho sebetsoa ka eona e hlahisa mefuta e fapaneng e nang le thepa le lits'ebetso tse fapaneng.

1.Microcrystalline Cellulose (MCC):

MCCe hlahisoa ka ho phekola likhoele tsa cellulose ka li-mineral acid, tse hlahisang likaroloana tse nyane tsa kristale.
Ts'ebeliso: E sebelisoa haholo joalo ka sehlahisoa sa bulking, binder, le disintegrant mefuteng ea meriana joalo ka matlapa le li-capsules. Ka lebaka la tlhaho ea eona e sa sebetseng le ho hatelloa ha eona ka mokhoa o babatsehang, MCC e tiisa kabo e tšoanang ea lithethefatsi le ho thusa ho lokolloa ha lithethefatsi.

2. Cellulose Acetate:

Cellulose acetate e fumanoa ka selulose ea acetylating e nang le acetic anhydride kapa acetic acid.
Lisebelisoa: Mofuta ona oa selulose o atisa ho sebelisoa ha ho etsoa likhoele bakeng sa masela, ho kenyelletsa le liaparo le upholstery. E boetse e sebelisoa ho etsa lifensetere tsa lisakerete, filimi ea lifoto, le mefuta e fapaneng ea li-membrane ka lebaka la sebopeho sa eona se sa khoneheng.

3. Ethylcellulose:

Ethylcellulose e tsoa ho selulose ka ho e arabela ka ethyl chloride kapa ethylene oxide.
Lisebelisoa: Lintho tsa eona tse babatsehang tsa ho etsa lifilimi le ho hanyetsa lihlapolli tsa lintho tse phelang li etsa hore ethylcellulose e loketse ho roala matlapa a meriana, e fana ka tokollo e laoloang ea lithethefatsi. Ho phaella moo, e sebelisoa ho etsa li-inks, li-adhesives le liphahlo tse khethehileng.

4.Hydroxypropyl Methylcellulose (HPMC):

HPMCe entsoe ka ho kenya lihlopha tsa hydroxyl tsa selulose ka lihlopha tsa methyl le hydroxypropyl.
Tšebeliso: HPMC e sebetsa e le setei, se tsitsitseng, le emulsifier liindastering tse fapaneng, ho kenyeletsoa lijo, litlolo, le meriana. Hangata e fumanoa lihlahisoa tsa tlhokomelo ea motho joalo ka litlolo, litlolo le litlolo, hammoho le lijong tse kang li-sauces, li-dressings le ice cream.

5.Sodium Carboxymethyl Cellulose (CMC):

CMC e hlahisoa ka ho phekola selulose ka chloroacetic acid le alkali.
Lisebelisoa: Ka lebaka la ho qhibiliha ha metsi a mangata le thepa ea eona e teteaneng,CMCe sebelisoa haholo joalo ka mokhoa oa ho tsitsisa le oa viscosity lihlahisoa tsa lijo, meriana le lits'ebetso tsa indasteri. Hangata e fumanoa linthong tse halikiloeng, lihlahisoa tsa lebese, sesepa sa meno le lihlapa.

6.Nitrocellulose:

Nitrocellulose e hlahisoa ke nitrating cellulose ka motsoako oa nitric acid le sulfuric acid.
Lisebelisoa: E sebelisoa haholo ho etsa liqhomane, lilakane le lipolasetiki tsa celluloid. Li-lacquers tse thehiloeng ho nitrocellulose li tumme ka ho qeta lehong le liaparo tsa likoloi ka lebaka la ho omisa ka potlako le thepa e phahameng ea gloss.

7.Bacterial Cellulose:

Bacterial cellulose e entsoe ke mefuta e itseng ea libaktheria ka ho belisoa.
Tšebeliso: Lintho tsa eona tse ikhethang, tse kenyelletsang bohloeki bo phahameng, matla a tsitsitseng, le biocompatibility, li etsa hore selulose ea baktheria e be ea bohlokoa lits'ebetsong tsa biomedical tse kang ho roala maqeba, li-scaffolds tsa boenjiniere ba lisele le mekhoa ea ho tsamaisa lithethefatsi.

Mefuta e fapaneng ea selulose e fana ka lits'ebetso tse fapaneng ho pholletsa le liindasteri tse fapaneng, ho kenyeletsoa meriana, masela, lijo, litlolo le tlhahiso. Mofuta o mong le o mong o na le thepa e ikhethang e etsang hore e tšoanelehe bakeng sa ts'ebeliso e itseng, ho tloha ho fana ka ts'ehetso ea sebopeho matlapeng a meriana ho ntlafatsa sebopeho sa lihlahisoa tsa lijo kapa ho sebetsa e le mokhoa o mong o tsitsitseng oa biotechnology. Ho utloisisa liphapang tsena ho nolofalletsa khetho e hlophisitsoeng ea mefuta ea cellulose ho fihlela litlhoko tse ikhethang tsa ts'ebetso lits'ebetsong tse fapaneng.
