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 ka tšireletso 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.
