Selulose ea Ethyl

Ethyl cellulose ke motsoako oa cellulose, e leng polymer ea tlhaho e fumanoang limela. E hlahisoa ka karabelo ea cellulose le ethyl chloride ha ho e-na le catalyst. Ethyl cellulose e sebelisoa haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ikhethang le ho tenyetseha ha eona. Mona ke litšobotsi tsa bohlokoa le ts'ebeliso ea ethyl cellulose:

1. Ho se qhibilihe ha metsi: Ethyl cellulose ha e qhibilihe ka metsing, e leng se etsang hore e lokele ho sebelisoa moo ho hlokahalang ho hanyetsa metsi. Thepa ena e boetse e lumella tšebeliso ea eona e le sekoahelo se sireletsang meriana le e le thepa e thibelang liphutheloana tsa lijo.
2. Ho qhibiliha ha metsoako ea lintho tse phelang: Ethyl cellulose e qhibiliha ka har'a metsoako e mengata ea lintho tse phelang, ho kenyeletsoa ethanol, acetone le chloroform. Ho qhibiliha hona ho etsa hore ho be bonolo ho sebetsana le ho kopanya lihlahisoa tse fapaneng, tse kang ho penta, lifilimi le enke.
3. Bokhoni ba ho Etsa Filimi: Ethyl cellulose e na le bokhoni ba ho etsa lifilimi tse tenyetsehang le tse tšoarellang ha e oma. Thepa ena e sebelisoa lits'ebetsong tse kang lipente tsa matlapa meriana, moo e fanang ka lera le sireletsang metsoako e sebetsang.
4. Thermoplasticity: Ethyl cellulose e bontša mokhoa oa 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 lokele ho sebelisoa likhomaretsing tse chesang le polasetiking e ka boptjoang.
5. Ho se Sebete ha Lik'hemik'hale: Ethyl cellulose ha e sebetse ka lik'hemik'hale 'me e hanela li-acid, li-alkali le boholo ba li-solvents tsa tlhaho. Thepa ena e etsa hore e lokele ho sebelisoa mefuteng moo botsitso le ho lumellana le metsoako e meng li leng bohlokoa.
6. Ho Ikamahanya le Lintho Tse Phelang: Ethyl cellulose ka kakaretso e nkoa e bolokehile (GRAS) bakeng sa tšebeliso ea meriana, lijo le lihlahisoa tsa litlolo. Ha e na chefo 'me ha e behe kotsi ea litlamorao tse mpe ha e sebelisoa kamoo ho reriloeng kateng.
7. Tokoloho e Laoloang: Ethyl cellulose hangata e sebelisoa mefuteng ea meriana ho laola ho lokolloa ha metsoako e sebetsang. Ka ho lokisa botenya ba sekoahelo sa ethyl cellulose matlapeng kapa li-pellets, sekhahla sa ho lokolloa ha meriana se ka fetoloa ho fihlela liprofaele tsa tokollo tse telele kapa tse tšoarellang.
8. Sekoahelo le Sekoahelo: Ethyl cellulose e sebelisoa e le sekoahelo le sekoahelo lits'ebetsong tse fapaneng, ho kenyeletsoa enke, lipente le likhomaretsi. E ntlafatsa thepa ea rheological ea liforomo 'me e thusa ho fihlela botsitso le ho teteana ho lakatsehang.

ethyl cellulose ke polymer e feto-fetohang e nang le mefuta e mengata ea lits'ebetso liindastering tse kang meriana, lijo, litlolo, liphahlo le likhomaretsi. Motsoako oa eona o ikhethang oa thepa o etsa hore e be motsoako oa bohlokoa mefuteng e mengata, moo e tlatsetsang botsitsong, ts'ebetsong le ts'ebetsong.
