1. Mokhoa oa ho qhalana oa Throll cellulose
Sesebelisoa sa Ethyl (EC) ke k'hemik'hale e entsoeng ka lisebelisoa tsa tlhaho tsa moea, tse nang le biocotatication e ntle, e seng litšila le ho se tsotelle. Kaha sebopeho sa eona se na le palo e kholo ea li-hydroxyl le lihlopha tsa meralo, e na le liphephetso tse ling tsa ho qhala. Bakeng sa ho qhibiliha ka katleho celnyl cellengse ea Ethyl, mekhoa e khethehileng ea Distoration le li-solvel li hlokahala.
Khetho ea Solvent
Khoele ea selenyl ea Ethyl e itšetlehile ka boima ba eona ba limolek'hule, boitšoaro ba matla a boemo bo itseng le solvent e khethiloeng. Ka lebaka la litšobotsi tsa sebopeho tsa senoelo sa Ethyl, hangata ha li qobelle ka metsing, empa hangata li ka qhibiliha ka li-solvents tse fapaneng tsa khale. Hangata litekanyetso tse sebelisetsoang li kenyelletsa:
Li-solvents tsa ho sebelisana: joalo ka Ethanol, Isitolropanol, jj.
Ether Lolsvent: Tse kang Dibethyl sulfoxide (DMSso), Chloroform, EtC.
Kenel solvent: e kang Acetone, jj.
Li-solvents tse koetsoeng: joalo ka chloroform, carbon tetrarator, jj.
Mehato ea dissuretion
Mehato ea khefu ea Throlulo ea Ethyl Cellulose ka kakaretso e tjena:
Khetho ea pele: Ka hloko etha selefo sa motlakase ho solvent e khethiloeng, netefatsa hore palo ea qhobosheane e lekane ho koahela seqhobosheane ea Ethyl
Ho felisoa ha Deoption: Haeba ho le thata ho hlakola mocheso oa kamore, mocheso o ka eketsoa ka makhetlo a 70 ° Cerselo ho etsa qhobosheane.
Desication: Kamora hore ho felisoa ha pherekano ho phethetsoe, haeba ho lumelloa ho hohola kapa ho ema nako ea tharollo ea ho qetela.
Ea hlokolosi nakong ea ho qhalana
TLHALOSO EA TLHOKOMELISO: Ho phahameng haholo kameho ea Ethyl cem celnyl ho ka baka thata ho khesoa. Ho khothalletsoa ho fetola linyebeleng ha ho hlokahala.
Khetho ea Solvent: Mefuta e fapaneng ea Ethyl cellengse (joalo ka boima ba limolek'hule tsa bomonamo, ho ba le mekhoa e fapaneng ea motlakase) ba nang le li-solven. Ho khetha Solvent e loketseng ho thusa ho ntlafatsa ts'ebetso ea qhoriso ea qhoriso.
2. Melaoana ea sehlooho ea Ethyl cellulose
Sehloho sa Ethyl se sebelisoa haholo masimong a mangata ka lebaka la thepa ea eona e ntle ea 'mele le ea lik'hemik'hale (joalo ka thepa e etsang lifilimi, botsitso, jj.). Mona ke tse ling tsa ts'ebeliso e ka sehloohong:
Seteishene se laoloang ke lithethefatsi
Sesebelisoa sa Ethyl se na le semelo se hantle sa biocompitatitatice E ka ntlafatsa ts'ebetso ea lithethefatsi le ho fokotsa litlamorao ka ho laola lebelo le ho fumana nako ea tokollo ea lithethefatsi. Lisebelisoa tse tloaelehileng li kenyelletsa lithethefatsi tsa molomo, li-transches tsa lithethefatsi, jj.
Boea le lisebelisoa tsa membrane
Noel ea Ethyl e na le matla a matle a lifilimi, kahoo e sebelisoa haholo lijong le makhapetla a lithethefatsi. E ka theha letšoele le letšo ebile le le junifomo ho sireletsa lintho tse ka hare ho tikolohong ea kantle ebe e eketsa botsitso le bophelo ba sehatsetsing. Likopo tse tloaelehileng tsa koae li kenyelletsa ho koata tsoekere ea tsoekere, koae ea lithethefatsi, jj.
Indasteri ea lijo
Indastering ea lijo, Celnyl Cellulose e sebelisoa haholo e le ea eketsang lijo. E ka sebelisoa e le bolo ea thippner, Stabilizer, Emulfifier, jj. Ho ntlafatsa sebopeho le tatso ea lijo. Ka mohlala, Celnyl Cellingulose e ka sebelisoa e le sebaka sa lijo tsa lijo tse tlase ho thusa ho laola litaba tsa mafura le tsoekere.
Indasteri ea Li-cosmetics
Lichelete, Celtiki ea Ethyl hangata e sebelisoa e le bolo ea thippner, emmolifier le ea pele, e ka ntlafatsang emulsion, e khutsitseng ha e sebelisoa. Mohlala, Celnyl Cll Nelleng le ka fumanoa lihlahisoa tse kang litlolo tsa sefahleho, batho ba bangata le li-listostes.
Pampiri le ts'ebetso ea masela
Joaloka sekhobeli sa celluulose ea tlhaho, Belnyl CelnyLulose e phetha karolo ea bohlokoa ts'ebetsong ea pampiri le masela. E ka eketsa matla a pampiri, e ntlafatse boleng ba bokapele, le ho ntlafatsa maemo a lesifa le ho chesoa ha masela.
Likotsi le lipente
Joaloka filimi ea nakong e fetileng bakeng sa makhapetla a Ethyl le hangata a sebelisoa ho hlahisa lipere le bokooa. E ka ntlafatsa ho hloka boitlamo, botsitso le ho khomarela bokahare ba bodima tsa koae.
Lisebelisoa tse Bonolo
Ka lebaka la bokhabane ba eona le chefo e tlase, seleroml cellulose e ithutoang bakeng sa nts'etsopele ea thepa ea tikoloho. Mohlala, masimong a kalafo ea metsi le ntlafatso ea mobu, litšobotsi tsa tšireletso tsa tikoloho ea selenyl cepy e etsa hore e be boitsebiso bo botala ka bokhoni bo boholo.
Joaloka thepa ea bohlokoa ea lik'hemik'hale, selefou e phetha karolo ea bohlokoa indastering e mengata. Mokhoa oa eona oa ho felisoa haholo ho latela khetho ea li-solvelt, 'me li-solvents tse tloaelehileng li kenyelletsa li-solvelts tsa manyolo,' me li-solvents tse tloaelehileng li kenyelletsa linoha, e-ithuta le li-Ketone. Ho latela ts'ebeliso e fapaneng, Cllyl Cllouddlese e ka sebelisoa haholo tokollo e sebelisitsoeng e laoloang, ea lijo, lihlahisoa tse ling, ebile li na le botsoalle bo botle le botsoalle bo botle. Ka tlhoko e ntseng e eketseha ea lisebelisoa tse nang le botsoalle le tikoloho, mothutso oa ts'ebetso oa Cemel Cellulose o pharaletse haholo.
