Ho Utloisisa Litšobotsi tsa Lik'hemik'hale tsa Ethyl Cellulose

Selulose ea ethyl ke polymer e feto-fetohang e nang le mefuta e mengata ea lits'ebetso ho pholletsa le liindasteri tse kang meriana, lijo, liphahlo le tlhokomelo ea botho. Ho utloisisa litšobotsi tsa eona tsa lik'hemik'hale ho bohlokoa bakeng sa ho sebelisa bokhoni ba eona mefuteng le lits'ebetsong tse fapaneng.

Sebopeho sa Lik'hemik'hale:

Ethyl cellulose e nkiloe ho cellulose, e leng polymer ea tlhaho e fumanoang limela. Ka phetoho ea lik'hemik'hale, lihlopha tsa ethyl li kenngoa mokokotlong oa cellulose, e leng se fellang ka ho thehoa ha ethyl cellulose. Sebopeho sa lik'hemik'hale sa ethyl cellulose se ka emeloa ka tsela e latelang:

Lihlopha tsa Cellulose+Ethyl→EthylCellulose Lihlopha tsa Cellulose+Ethyl→EthylCellulose

Ho se rate metsi:

E 'ngoe ea litšobotsi tsa bohlokoa tsa lik'hemik'hale tsa ethyl cellulose ke tlhaho ea eona ea ho se tšabe metsi. Ho kenngoa ha lihlopha tsa ethyl mokokotlong oa cellulose ho fokotsa polarity ea polymer, e leng se fellang ka ho fokotseha ha kamano ea metsi. Ho se tšabe metsi hona ho etsa hore ethyl cellulose e se qhibilihe metsing empa e qhibilihe ka har'a metsoako ea lintho tse phelang e kang ethanol, toluene le chloroform.

Thermoplasticity:

Ethyl cellulose e bonts'a boits'oaro ba thermoplastic, ho bolelang hore e nolofala ha e futhumatsoa mme ea tiea ha e pholile ntle le ho senyeha ka lik'hemik'hale. Thepa ena e etsa hore ethyl cellulose e lokele mekhoa e fapaneng ea ts'ebetso e kang ho ntša, ho bopa le ho lahla filimi. Sebopeho sa thermoplastic sa ethyl cellulose se lumella tlhahiso ea lifilimi, lipente le lintho tse bōpiloeng tse nang le thepa e lakatsehang ea mechini.

Matlotlo a ho Etsa Filimi:

Ha e qhibiliha ka har'a metsoako e loketseng ea lintho tse phelang, ethyl cellulose e ka etsa lifilimi tse hlakileng, tse tenyetsehang le tse bonaletsang ha motsoako o fetoha mouoane. Lifilimi tsena li na le thepa e ntle ea thibelo khahlanong le mongobo, likhase le oli, e leng se etsang hore li lokele ho sebelisoa ho koahela, ho kenya lintho ka har'a capsule le ho paka.

Ho lumellana:

Ethyl cellulose e tsamaisana le mefuta e mengata ea li-polymer tse ling, li-plasticizer le li-additives, e leng se lumellang ho etsoa ha metsoako e etselitsoeng motho ka mong e nang le thepa e itseng. E ka kopanngoa le li-polymer tse ling tse kang polyvinyl acetate (PVA), li-resin tsa acrylic, kapa li-derivatives tsa cellulose ho fihlela litšobotsi tse lakatsehang tsa ts'ebetso ho li-coatings, li-glue le matrices bakeng sa ho fana ka meriana e laoloang.

Ho Tsitsisa ha Lik'hemik'hale:

Ethyl cellulose e bonts'a botsitso bo botle ba lik'hemik'hale, e hanela ho senyeha ha khanya, mocheso le oksijene. Botsitso bona bo netefatsa ts'ebetso ea nako e telele ea lihlahisoa tse nang le ethyl cellulose, haholo-holo lits'ebetsong moo ho tšoarella le bophelo ba shelefo li leng bohlokoa, joalo ka matlapa a meriana le lipente.

Qetello:

Qetellong, ethyl cellulose e na le litšobotsi tse 'maloa tsa bohlokoa tsa lik'hemik'hale tse e etsang hore e be polymer ea bohlokoa liindastering tse fapaneng. Ho se tšabe metsi ha eona, ho ba thermoplasticity, litšobotsi tsa ho etsa filimi, ho lumellana ha eona le botsitso ba lik'hemik'hale ho nolofalletsa tšebeliso ea eona lits'ebetsong tse fapaneng, ho kenyeletsoa meriana, lijo, liphahlo le tlhokomelo ea botho. Ho utloisisa litšobotsi tsena tsa lik'hemik'hale ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso le katleho ea liforomo tse nang le ethyl cellulose, e leng se lebisang nts'etsopele ea lihlahisoa tse ncha tse nang le litšobotsi le ts'ebetso e lakatsehang.
