Ho na le mefuta e 'maloa ea cellulose, 'me phapang ea tšebeliso ea eona ke efe?

Cellulose ke polymer ea tlhaho e feto-fetohang le e ngata e fumanoang maboteng a sele a limela, e fanang ka tšehetso ea sebopeho le ho tiea. E entsoe ka li-unit tsa glucose tse hokahaneng hammoho ka litlamo tsa β-1,4-glycosidic. Le hoja cellulose ka boeona e le ntho e ts'oanang, tsela eo e hlophisitsoeng le ho sebetsoa ka eona e fella ka mefuta e fapaneng e nang le thepa le lits'ebetso tse fapaneng.

1. Selulose e nyenyane e kang microcrystalline (MCC):

MCCe hlahisoa ka ho phekola likhoele tsa cellulose ka li-acid tsa diminerale, e leng se fellang ka likaroloana tse nyane tsa kristale.
Tšebeliso: E sebelisoa haholo e le sesebelisoa sa ho bokella, ho kopanya, le ho qhala metsoako ea meriana e kang matlapa le li-capsule. Ka lebaka la tlhaho ea eona e sa etseng letho le ho hatelloa ho babatsehang, MCC e netefatsa kabo e tšoanang ea meriana 'me e nolofalletsa ho lokolloa ha meriana.

2. Acetate ea selelulose:

Cellulose acetate e fumanoa ka ho kopanya cellulose le acetylating ka acetic anhydride kapa acetic acid.
Tšebeliso: Mofuta ona oa cellulose o atisa ho sebelisoa tlhahisong ea likhoele bakeng sa masela, ho kenyeletsoa liaparo le upholstery. O boetse o sebelisoa tlhahisong ea li-filter tsa sakerete, filimi ea lifoto, le mefuta e fapaneng ea lera ka lebaka la tlhaho ea oona e kenellang hanyane.

3. Ethylcellulose:

Ethylcellulose e nkiloe ho tsoa ho cellulose ka ho e kopanya le ethyl chloride kapa ethylene oxide.
Tšebeliso: Matla a eona a matle a ho etsa filimi le ho hanyetsa li-solvents tsa tlhaho ho etsa hore ethylcellulose e lokele ho maneha matlapa a meriana, e leng se fanang ka tokollo e laoloang ea meriana. Ho feta moo, e sebelisoa tlhahisong ea enke, likhomaretsi le liphahlo tse khethehileng.

4. Hydroxypropyl Methylcellulose (HPMC):

HPMCe hlahisoa ka ho kenya lihlopha tsa hydroxyl tsa cellulose sebakeng sa lihlopha tsa methyl le hydroxypropyl.
Tšebeliso: HPMC e sebetsa e le setefatsi, se tsitsisang, le se kopanyang liindasteri tse fapaneng, ho kenyeletsoa lijo, litlolo le meriana. E fumanoa hangata lihlahisoa tsa tlhokomelo ea botho tse kang lotions, litlolo le mafura, hammoho le lits'ebetsong tsa lijo tse kang lisoso, liaparo tse tlotsang le ice cream.

5. Selulose ea Sodium Carboxymethyl (CMC):

CMC e hlahisoa ka ho phekola cellulose ka chloroacetic acid le alkali.
Tšebeliso: Ka lebaka la ho qhibiliha ha eona ka metsi a mangata le thepa ea ho teteana,CMCe sebelisoa haholo e le sesebelisoa sa ho tsitsisa le ho fetola viscosity lihlahisoa tsa lijo, meriana le lits'ebetsong tsa indasteri. E fumanoa hangata linthong tse besitsoeng, lihlahisoa tsa lebese, sesepa sa meno le sesepa sa sesepa.

6.Nitrocellulose:

Nitrocellulose e hlahisoa ke nitrating cellulose ka motsoako oa nitric acid le sulfuric acid.
Tšebeliso: E sebelisoa haholo-holo tlhahisong ea liqhomane, li-lacquers le polasetiki ea celluloid. Li-lacquers tse thehiloeng ho nitrocellulose li tumme ho khabisong ea lehong le ho penteng likoloi ka lebaka la ho omella ha tsona kapele le thepa ea tsona e benyang haholo.

7. Selulose ea Baktheria:

Selulose ea baktheria e hlahisoa ke mefuta e itseng ea libaktheria ka ho belisoa.
Tšebeliso: Thepa ea eona e ikhethang, ho kenyeletsoa bohloeki bo phahameng, matla a ho thapolla le ho lumellana ha lintho tse phelang, e etsa hore cellulose ea baktheria e be ea bohlokoa lits'ebetsong tsa bongaka tse kang masela a maqeba, li-scaffolds tsa boenjiniere ba lisele, le litsamaiso tsa ho fana ka meriana.

Mefuta e fapaneng ea cellulose e fana ka mefuta e mengata ea lits'ebetso 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 lokele lits'ebeliso tse itseng, ho tloha ho faneng ka tšehetso ea sebopeho matlapeng a meriana ho ea ho ntlafatsa sebopeho sa lihlahisoa tsa lijo kapa ho sebeletsa e le mokhoa o mong o tsitsitseng oa theknoloji ea baeloji. Ho utloisisa liphapang tsena ho nolofalletsa khetho e ikhethileng ea mefuta ea cellulose ho fihlela litlhoko tse itseng tsa ts'ebetso lits'ebetsong tse fapaneng.
