Ethyl cellulose

Ethyl cellulose e tsoa ho cellulose, polima ea tlhaho e fumanoang limela. E hlahisoa ka karabelo ea selulose e nang le ethyl chloride ka boteng ba catalyst. Ethyl cellulose e sebelisoa haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang le ho feto-fetoha ha maemo. Mona ke tse ling tsa litšobotsi tsa bohlokoa le ts'ebeliso ea ethyl cellulose:

1. Insolubility ka Metsing: Ethyl cellulose ha e qhibilihe ka metsing, e leng se etsang hore e tšoanelehe bakeng sa lits'ebetso moo ho hlokahalang ho thibela metsi. Thepa ena e boetse e lumella hore e sebelisoe e le tšireletso e sireletsang meriana le e le ntho e thibelang ho paka lijo.
2. Solubility in Organic Solvents: Ethyl cellulose e qhibiliha ka har'a mefuta e mengata e fapaneng ea metsoako ea tlhaho, ho kenyelletsa ethanol, acetone, le chloroform. Motsoako ona o etsa hore ho be bonolo ho sebetsa le ho etsa lihlahisoa tse fapaneng, joalo ka lirafshoa, lifilimi le li-inks.
3. Bokhoni ba ho Etsa Lifilimi: Ethyl cellulose e na le bokhoni ba ho etsa lifilimi tse tenyetsehang le tse tšoarellang ha li omisoa. Thepa ena e sebelisoa lits'ebetsong tse kang liphahlo tsa letlapa litlhare, moo e fanang ka lera le sireletsang bakeng sa metsoako e sebetsang.
4. Thermoplasticity: Ethyl cellulose e bonts'a boits'oaro ba thermoplastic, ho bolelang hore e ka nolofatsoa le ho bōptjoa ha e futhumatsoa ebe e tiea ha e pholile. Thepa ena e etsa hore e tšoanelehe ho sebelisoa ka har'a likhomaretsi tse qhibilihang tse chesang le lipolasetiki tse bopehang.
5. Ho se Fellehe ha Lik'hemik'hale: Ethyl cellulose ha e sebetse ka lik'hemik'hale 'me e hanyetsana le li-acids, alkalis, le boholo ba metsoako ea tlhaho. Thepa ena e etsa hore e loketse ho sebelisoa ha ho etsoa libopeho moo botsitso le ho lumellana le lisebelisoa tse ling li leng bohlokoa.
6. Biocompatibility: Ethyl cellulose ka kakaretso e nkuoa e bolokehile (GRAS) bakeng sa tšebeliso ea meriana, lijo le lihlahisoa tsa litlolo. Ha e na chefo ebile ha e behe kotsi ea litlamorao tse mpe ha e sebelisoa joalo ka ha e reriloe.
7. Phatlalatso e Laolang: Ethyl cellulose e atisa ho sebelisoa mefuteng ea meriana ho laola ho lokolloa ha metsoako e sebetsang. Ka ho fetola botenya ba ethyl cellulose coat holim'a matlapa kapa li-pellets, tekanyo ea ho lokolloa ha lithethefatsi e ka fetoloa ho finyella litlaleho tse atolositsoeng kapa tse tsitsitseng tsa tokollo.
8. Binder and Thickener: Ethyl cellulose e sebelisoa e le setlamo le setenya lits'ebetsong tse fapaneng, ho kenyeletsoa lienke, lirafshoa le likhomaretsi. E ntlafatsa thepa ea rheological ea formulations mme e thusa ho fihlela tumellano e lakatsehang le viscosity.

ethyl cellulose ke polymer e feto-fetohang e nang le lits'ebetso tse fapaneng liindastering tse joalo ka meriana, lijo, litlolo, litlolo le likhomaretsi. Motsoako oa eona o ikhethang oa thepa o etsa hore e be motsoako oa bohlokoa mekhoeng e mengata, moo e tlatsetsang botsitso, ts'ebetso le ts'ebetso.
