U ka etsa ethyl cellulose joang?

Ethyl cellulose ke polymer ea maiketsetso e entsoeng ka selulose, motsoako oa tlhaho o fumanoang limela. Ke phofo e tšoeu, e sa nkheng, e sa latsoeheng e sa qhibiliheng ka metsing le boholo ba metsoako ea lintho tse phelang. Ethyl cellulose EC e sebelisoa mefuteng e fapaneng ea ts'ebeliso, ho kenyeletsoa liphahlo, likhomaretsi le litlhare.

Mokhoa oa ho etsa ethyl cellulose o kenyelletsa mehato e mengata. Mohato oa pele ke ho fumana cellulose, e ka fumanoang mehloling ea limela e kang k'hothone, lehong kapa lehlaka. Joale cellulose e tšeloa ka asiti e matla, e kang sulfuric acid, ho arola selulose hore e be likaroloana tsa eona tsa limolek’hule tsa tsoekere. Joale limolek'hule tsa tsoekere li sebetsa ka joala ba ethyl ho etsa ethyl cellulose.

Joale ethyl cellulose e hloekisoa ka mokhoa o bitsoang "fractional precipitation". Sena se kenyelletsa ho eketsa motsoako oa motsoako oa ethyl cellulose, o etsang hore ethyl cellulose e tsoe mothapong. Joale ethyl cellulose e omisitsoeng ea bokelloa ebe e omisoa.

Mohato oa ho qetela ke ho fetola cellulose e omisitsoeng ea ethyl hore e be phofo. Sena se etsoa ka ho sila cellulose ea ethyl hore e be phofo e ntle. Joale phofo e loketse ho sebelisoa mefuteng e sa tšoaneng.

Ethyl cellulose ke sesebelisoa se feto-fetohang se ka sebelisoang lits'ebetsong tse fapaneng. E sebelisoa ho etsa litlolo, likhomaretsi le litlhare, 'me e ka sebelisoa ho etsa lifilimi, likhoele le li-gel. E boetse e sebelisoa ha ho etsoa lipente, lienke le lihlahisoa tse ling. Ethyl cellulose e boetse e sebelisoa e le ntho e matlafatsang lihlahisoa tsa lijo, hape e le stabilizer ho litlolo.
