Ho qhibiliha ha ethyl cellulose ka har'a acetone

Ethyl cellulose ke polymer e sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa meriana, lijo le tlhokomelo ea motho. E tsebahala ka thepa ea eona e babatsehang ea ho etsa lifilimi, ho lumellana ho phahameng le lisebelisoa tse ling, le ho hanyetsa lik'hemik'hale hantle le maemo a tikoloho. E 'ngoe ea lintho tse ka sehloohong tsa ethyl cellulose ke ho qhibiliha ha eona, ho ka fapana ho latela mokelikeli o sebelisitsoeng.

Acetone ke mokelikeli o tloaelehileng o sebelisoang hangata ha ho etsoa lifilimi le liphahlo tsa ethyl cellulose. Ethyl cellulose e qhibiliha hanyane ka har'a acetone, ho bolelang hore e ka qhibiliha ho isa bohōleng bo itseng empa e kanna ea se ke ea qhibiliha ka botlalo. Tekanyo ea ho qhibiliha ha ethyl cellulose ka acetone e ipapisitse le lintlha tse fapaneng joalo ka boima ba limolek'hule, tekanyo ea ethoxylation, le khatello ea polymer.

Ka kakaretso, boima ba limolek'hule tse phahameng tsa ethyl cellulose hangata ha li qhibilihe ka har'a acetone ha li bapisoa le boima ba molek'hule ethyl cellulose. Lebaka ke hobane li-polymers tse phahameng tsa boima ba limolek'hule li na le tekanyo e phahameng ea polymerization, e bakang sebopeho se rarahaneng le se pakiloeng ka thata se hanyetsanang le ho rarolloa. Ka mokhoa o ts'oanang, ethyl cellulose e nang le tekanyo e phahameng ea ethoxylation e atisa ho qhibiliha hanyane ka har'a acetone ka lebaka la ho eketseha ha hydrophobicity ea polymer.

Ho qhibiliha ha ethyl cellulose ka har'a acetone ho ka boela ha angoa ke bongata ba polymer ka har'a solvent. Maemong a tlase, ethyl cellulose e na le monyetla oa ho qhibiliha ka har'a acetone, athe ha e le maemong a holimo, ho qhibiliha ho ka fokotseha. Sena se bakoa ke taba ea hore maemong a phahameng, limolek'hule tsa ethyl cellulose li na le monyetla oa hore li sebelisane, li etsa marang-rang a liketane tsa polymer tse sa qhibiliheng ka har'a mokelikeli.

Ho qhibiliha ha ethyl cellulose ka acetone ho ka ntlafatsoa ka ho eketsoa ha li-solvents tse ling kapa li-plasticizers. Ka mohlala, ho eketsoa ha ethanol kapa isopropanol ho acetone ho ka eketsa ho qhibiliha ha ethyl cellulose ka ho senya likamano tsa intermolecular pakeng tsa liketane tsa polymer. Ka mokhoa o ts'oanang, ho eketsoa ha li-plasticizers tse kang triethyl citrate kapa dibutyl phthalate ho ka eketsa ho qhibiliha ha ethyl cellulose ka ho fokotsa matla a intermolecular pakeng tsa liketane tsa polymer.

Ka bokhutšoanyane, ethyl cellulose e qhibiliha ka mokhoa o itseng ka har'a acetone, 'me ho qhibiliha ha eona ho ka fapana ho latela lintlha tse fapaneng tse kang boima ba molek'hule, tekanyo ea ethoxylation le mahloriso a polymer. Ho qhibiliha ha ethyl cellulose ka har'a acetone ho ka matlafatsoa ke ho eketsoa ha li-solvents tse ling kapa li-plasticizers, e leng ho etsang hore e be polymer e ka sebelisoang mesebetsing e fapaneng.
