Ethyl cellulose ke polymer e feto-fetohang e nang le mefuta e mengata ea ts'ebeliso, ho tloha ho meriana ho ea ho litlolo ho isa ho lisebelisoa tsa lijo.Thepa ea eona e ka fapana haholo ho latela kereiti ea eona, e khethoang ke lintlha tse kang boima ba molek'hule, tekanyo ea ho fetola, le kabo ea boholo ba likaroloana.
1.Selelekela ho Ethyl Cellulose
Ethyl cellulose e tsoa ho cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa semela.E entsoe ka ethylation ea cellulose, moo lihlopha tsa hydroxyl mokokotlong oa cellulose li nkeloang sebaka ke lihlopha tsa ethyl.Phetoho ena e fana ka thepa e ikhethang ho cellulose ea ethyl, ho kenyelletsa le bokhoni bo botle ba ho etsa filimi, ho hanyetsa lik'hemik'hale, le botsitso ba mocheso.
2.Mephato e Tlase ho isa ho e Mahareng ea Boima ba Limolek'hule:
Limaraka tsena hangata li na le boima ba limolek'hule ho tloha ho 30,000 ho isa ho 100,000 g / mol.
Li khetholloa ka viscosity ea tsona e tlaase le litekanyetso tsa ho qhibiliha ka potlako ha li bapisoa le litekanyetso tse phahameng tsa boima ba limolek'hule.
Lisebelisoa:
Li-coatings: Li sebelisoa e le li tlamahanngoa lirapeng tsa matlapa, lipilisi le li-granules litlhare.
Phatlalatso e Laolang: Ho hiroa lits'ebetsong tsa phano ea lithethefatsi tse laoloang moo ho batloang ho qhaloa ka potlako.
Li-inks: Li sebelisoa e le li-thickeners le li-agent tsa ho etsa lifilimi ho li-inks tsa khatiso.
3.Mephato e Phahameng ea Boima ba Limolek'hule:
Limaraka tsena li na le boima ba limolek'hule hangata bo fetang 100,000 g/mol.
Li bonts'a viscosity e phahameng le litekanyetso tse liehang tsa ho qhibiliha, e leng se etsang hore li tšoanelehe bakeng sa lihlahisoa tse sa khaotseng.
Lisebelisoa:
Tokollo e Ts'oarellang: E loketse ho theha liforomo tsa litekanyetso tsa tokollo e tsitsitseng ka har'a meriana, ho fana ka tokollo ea nako e telele ea lithethefatsi.
Encapsulation: E sebelisoa ho mahlale a encapsulation bakeng sa tokollo e laoloang ea litatso, monko o monate le metsoako e sebetsang.
Lifilimi tsa Barriers: E sebelisoa e le litšitiso ka har'a liphutheloana tsa lijo ho ntlafatsa bophelo ba sethala le ho thibela ho kenella ha mongobo.
4.Degree of Substitution (DS) Mefuta e fapaneng:
Ethyl cellulose e ka ba le likhato tse fapaneng tsa phetoho, e bonts'ang palo e tloaelehileng ea lihlopha tsa ethyl ka unit ea anhydroglucose ka ketane ea cellulose.
Mephato e nang le boleng bo phahameng ba DS e na le lihlopha tse ngata tsa ethyl ka yuniti e le 'ngoe ea selulose, e leng se bakang ho eketseha ha hydrophobicity le ho fokotseha ha ho qhibiliha ha metsi.
Lisebelisoa:
Khanyetso ea Metsi: Limaraka tse holimo tsa DS li sebelisoa liphaepheng le lifiliming moo ho hanyetsanang le metsi ho leng bohlokoa, joalo ka liphahlo tse thibelang mongobo bakeng sa matlapa le li-capsules.
Solvent Resistance: E loketse lits'ebetso tse hlokang khanyetso ho lihlapolli tsa tlhaho, joalo ka li-inks le liphahlo bakeng sa ho hatisa le ho paka.
5. Mefuta e fapaneng ea Boholo ba Karolo:
Ethyl cellulose e fumaneha ka mefuta e fapaneng ea boholo ba likaroloana, ho tloha ho likaroloana tsa boholo ba micrometer ho ea ho phofo e boholo ba nanometer.
Mefuta e metle ea likaroloana e fana ka melemo e kang ho ntlafatsoa ha dispersibility, ho roala boreleli, le ho lumellana ho ntlafatsang le lisebelisoa tse ling.
6. Likopo:
Nanoencapsulation: Likaroloana tsa Nanoscale ethyl cellulose li sebelisoa ho nanomedicine bakeng sa phepelo ea lithethefatsi, e nolofalletsang phepelo e lebisitsoeng le ho ntlafatsa katleho ea kalafo.
Nano Coatings: Li-powders tse ntle tsa ethyl cellulose li sebelisoa ka liphahlo tse khethehileng, tse kang li-barriers tsa li-barriers bakeng sa lisebelisoa tsa elektronike tse feto-fetohang le lisebelisoa tsa biomedical.
Ethyl cellulose ke polymer e feto-fetohang e nang le lits'ebetso tse fapaneng ho pholletsa le liindasteri, 'me limaraka tsa eona tse fapaneng li fana ka thepa e ikhethileng ho fihlela litlhoko tse ikhethang tsa tlhahiso.Ho tloha ho limaraka tse tlase ho isa ho tse phahameng tsa boima ba limolek'hule ho ea ho mefuta e fapaneng e ipapisitseng le tekanyo ea ho kenya sebaka le kabo ea boholo ba likaroloana, ethyl cellulose e fana ka mefuta e mengata ea likhetho bakeng sa baetsi ba lihlahisoa ba batlang tharollo mabapi le phano ea lithethefatsi, litlolo, li-encapsulation le ho feta.Ho utloisisa litšobotsi tsa sehlopha ka seng ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso le ho fihlela sephetho se lakatsehang lits'ebetsong tse fapaneng.
