Mefuta e fapaneng ea ethyl cellulose ke efe?

Ethylcellulose ke polymer e sebetsang ka mokhoa o fapaneng e nang le ts'ebeliso liindastering tse fapaneng, ho kenyeletsoa litlhare, liaparo, likhomaretsi le lijo. Likarolo tse fapaneng tsa ethylcellulose li etselitsoe ho fihlela litlhoko tse ikhethileng mabapi le viscosity, boima ba limolek'hule le thepa e 'ngoe.

Sebopeho sa Ethyl cellulose:

Ethylcellulose e tsoa ho cellulose, polymer ea tlhaho e fumanehang maboteng a lisele tsa semela. Ethylation ea selulose e kenyelletsa ho kenngoa ha lihlopha tsa ethyl tšebetsong ea hydroxyl (-OH) ea cellulose. Phetoho ena e fana ka thepa e ikhethang ea ethylcellulose, e etsa hore e qhibilihe ka har'a metsoako ea lintho tse phelang le ho fana ka bokhoni bo botle ba ho etsa lifilimi.

Litšobotsi tsa ethylcellulose:

Solubility: Ethylcellulose e qhibiliha ka har'a mefuta e fapaneng ea li-solvents tse kang joala, ketone, esters, joalo-joalo.
Thepa ea ho etsa lifilimi: Lintho tse ntle haholo tsa ho etsa lifilimi, tse loketseng ho roala le lifilimi.
Thermoplasticity: Ethylcellulose e bonts'a boitšoaro ba thermoplastic, e lumellang hore e bōptjoe kapa e thehoe ha e futhumala.
Inert: Ke inert ea lik'hemik'hale, e fana ka botsitso lits'ebetsong tse fapaneng.

E boetse e sebelisoa ha ho etsoa li-adhesives tse khethehileng le li-sealants.

3. Kereiti e phahameng ea viscosity:

Limaraka tsena li na le boima bo phahameng ba limolek'hule ka hona li-viscosity tse phahameng.
E loketse lits'ebetso tse hlokang likhoele tse teteaneng kapa lifilimi.
E sebelisoa ha ho etsoa liaparo tse sireletsang tse kang li-inks, lipente le li-varnish.

4. Boemo bo leka-lekaneng:

Limaraka tsena li na le boholo ba likaroloana tse nyane, tse thusang ho etsa hore litlolo li be bonolo le ho ntlafatsa ho hasana ka tharollo.
Fumana lits'ebetso tsa li-inks tsa khatiso tsa boleng bo holimo le likhoele bakeng sa ho lokisa libaka tse ntle.

5. Limaraka tse phahameng tsa ethoxy content:

Ethylcellulose e nang le tekanyo e phahameng ea ethoxylation.
E fana ka matla a ho qhibiliha ka har'a mefuta e mengata e fapaneng ea li-solvents.
E sebelisoa lits'ebetsong tse hlokang li-polymers tse phahameng tse qhibilihang, joalo ka mefuta e itseng ea meriana.

6. Boemo ba mongobo o tlase:

Ethyl cellulose e nang le mongobo o fokotsehileng.
E loketse lits'ebetso moo ho khathatseha ha mongobo, joalo ka tlhahiso ea meriana e sa ameneng le metsi.

7. Limaraka tsa Thermoplastic:

Limaraka tsena li bonts'a boits'oaro bo ntlafalitsoeng ba thermoplastic.
E sebelisoa ha ho bōptjoa moo thepa e hlokang ho nolofatsoa le ho etsoa ka mocheso o phahameng.

8. Boemo ba tokollo bo laoloang:

E etselitsoe metsoako ea meriana e hlokang ho lokolloa ha lithethefatsi ka nako e telele.
E etselitsoe ho fihlela li-kinetics tse lakatsehang ha li ntse li boloka botsitso.

Lisebelisoa tsa ethylcellulose:

1. Lithethefatsi:

Litokisetso tsa meriana tse laoloang.
Liaparo tsa letlapa bakeng sa masking a tatso le ho qhibiliha ho laoloang.
Binder bakeng sa granules tlhahiso ea matlapa.

2. Liaparo le li-ink:

Ho roala ho sireletsa bakeng sa libaka tse sa tšoaneng.
Li-inks tsa khatiso bakeng sa khatiso ea flexographic le gravure.
Liaparo tsa likoloi le tsa indasteri.

3. Likhomaretsi le li-sealants:

Likhomaretsi tse khethehileng bakeng sa lisebelisoa tse fapaneng.
Li-sealants tse sebelisetsoang ho kopanya le ho tiisa kahong le ho etsa thepa.

4. Indasteri ea lijo:

Liaparo tse jeoang holim'a litholoana le meroho li eketsa nako ea bophelo.
Ho kenyelletsa litatso le monko o monate.

5. Lipolasetiki le Mould:

Boitšoaro ba Thermoplastic lits'ebetsong tsa ho bopa.
E hlahisa lihlahisoa tse khethehileng tsa polasetiki.

6. Lihlahisoa tsa elektronike:

E sebelisoa ha ho etsoa liphahlo tse sireletsang bakeng sa likarolo tsa elektronike.

ha re phethela:
Limaraka tse fapaneng tsa ethylcellulose lia fumaneha ho kopana le mefuta e mengata ea lits'ebetso liindastering tse fapaneng. Ho tloha ho tsa meriana ho ea ho li-coatings le li-adhesives, ho feto-fetoha ha ethylcellulose ho itšetlehile ka litekanyetso tsa eona tse fapaneng, e 'ngoe le e' ngoe e etselitsoe ho finyella litlhoko tse itseng. Ha litlhoko tsa theknoloji le indasteri li ntse li tsoela pele ho fetoha, nts'etsopele ea limaraka tse ncha tsa ethylcellulose tse nang le thepa e ntlafetseng li ka bapala karolo ea bohlokoa ho finyella litlhoko tsa likopo tse hlahang. Ho utloisisa phapang pakeng tsa limaraka tsena ho thusa bahlahisi ho khetha ethylcellulose e nepahetseng ka ho fetisisa bakeng sa ts'ebeliso ea bona e khethehileng, ho netefatsa ts'ebetso e nepahetseng le katleho.
