Ethylcellulose (EC) ke polymer e feto-fetohang e nkiloeng ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela. Ethyl cellulose e fumanoa ka ho fetola selulose ka ho hlahisa lihlopha tsa ethyl. Phetoho ena e fana ka thepa e ikhethang ea polymer e e etsang hore e be ea bohlokoa bakeng sa lits'ebetso tse fapaneng tsa indasteri.
Litšobotsi tsa ethylcellulose:
1. Sebopeho sa lik'hemik'hale:
Ethylcellulose ke motsoako oa selulose o fumanoang ka ho phekola selulose ka ethyl chloride boteng ba alkali. Lihlopha tsa Ethyl li nka sebaka sa lihlopha tse ling tsa hydroxyl mohahong oa cellulose. Sebopeho sa lik'hemik'hale tsa ethylcellulose se khetholloa ke ho ba teng ha lihlopha tsa ethyl tse khomaretsoeng ho lihlopha tsa anhydroglucose tsa cellulose.
2. Sollubility:
Ethyl cellulose ha e qhibilihe ka metsing, e leng tšobotsi ea bohlokoa e e khethollang ho cellulose ea tlhaho. Leha ho le joalo, e bonts'a ho qhibiliha mefuteng e fapaneng ea lihlapolli tsa lintho tse phelang, ho akarelletsa le joala, li-ketone le li-hydrocarbon tse chlorinated. Solubility ena e etsa hore ethylcellulose e loketse mefuta e fapaneng ea ho roala le ho etsa lifilimi.
3. Thermal botsitso:
Ethyl cellulose e na le botsitso bo botle ba mocheso 'me e hanyetsa mocheso o phahameng. Thepa ena e bohlokoa bakeng sa lits'ebetso moo thepa e futhumatsang, joalo ka tlhahiso ea lifilimi le likoahelo.
4. Bokhoni ba ho etsa lifilimi:
E 'ngoe ea litšobotsi tse ikhethang tsa ethylcellulose ke bokhoni ba eona bo botle ba ho etsa lifilimi. Thepa ena e sebelisoa liindastering tsa meriana le lijo, moo ethylcellulose e sebelisetsoang ho etsa lifilimi bakeng sa ho fana ka lithethefatsi le liaparo tse jeoang, ka ho latellana.
5. Ho feto-fetoha ha maemo le polasetiki:
Lifilimi tsa Ethylcellulose li tsejoa ka ho feto-fetoha ha tsona le ho bōptjoa ha tsona, ho etsa hore li tšoanelehe bakeng sa lisebelisoa tse hlokang thepa e bonolo empa e phutholohile. Thepa ena e molemo haholo indastering ea meriana le ea ho paka.
6. Inert ea lik'hemik'hale:
Ethylcellulose ha e na lik'hemik'hale 'me ka hona e hanyetsa lik'hemik'hale tse ngata. Thepa ena e ntlafatsa botsitso ba eona libakeng tse fapaneng mme e holisa lits'ebetso tsa eona liindastering tse nang le ts'ebeliso ea lik'hemik'hale khafetsa.
7. Boima bo tlase:
Ethylcellulose e na le sekhahla se batlang se le tlase, se tlatsetsang ho bobebe ba eona. Thepa ena e na le molemo lits'ebetsong moo boima bo leng bohlokoa haholo, joalo ka tlhahiso ea lifilimi tse bobebe le liphahlo.
8. Ho lumellana le li-polymers tse ling:
Ethylcellulose e lumellana le mefuta e fapaneng ea li-polymers, e lumellang motsoako ho etsoa ka thepa e hlophisitsoeng. Khokahano ena e holisa ts'ebeliso ea eona ka ho etsa hore ho thehoe lisebelisoa tse nyalisitsoeng tse nang le thepa e ntlafalitsoeng.
9. Ha e latsoehe ebile ha e nkha:
Ethylcellulose ha e na tatso ebile ha e na monko 'me e loketse ho sebelisoa indastering ea meriana le ea lijo moo thepa ea kutlo e leng bohlokoa haholo.
Lisebelisoa tsa ethylcellulose:
1. Indasteri ea meriana:
Ho roala Letlapa: Ethylcellulose e atisa ho sebelisoa e le lisebelisoa tsa ho roala matlapa. Ho roala filimi ho fana ka tokollo e laoloang, tšireletso ho mabaka a tikoloho, le ho ntlafatsa ho latela melao ea mokuli.
Matrix ea ho lokolloa e laoloang: Ethylcellulose e sebelisoa ha ho etsoa lipilisi tsa matrix tse laoloang ke lithethefatsi. Litlaleho tsa tokollo tse laoloang li ile tsa finyelloa ka ho lokisa botenya ba seaparo sa ethylcellulose.
2. Indasteri ea lijo:
Liaparo tse jeoang: Ethylcellulose e sebelisoa e le seaparo se jeoang holim'a litholoana le meroho ho lelefatsa bophelo ba bona ba lishelefo le ho boloka bohloeki. Sebopeho se se nang tatso le se se nang monko sa ethylcellulose se tiisa hore ha se ame thepa ea kutlo ea lijo tse koahetsoeng.
3. Indasteri ea ho paka:
Lifilimi tsa ho paka tse feto-fetohang: Ethyl cellulose e sebelisoa ha ho etsoa lifilimi tse bonolo tsa ho paka. Ho feto-fetoha ha maemo, ho fokotseha ho fokolang le ho se sebetse ha lik'hemik'hale ho etsa hore e tšoanelehe bakeng sa lisebelisoa tse hlokang lisebelisoa tse bobebe le tse tsitsitseng lik'hemik'hale.
4. Li-inki le lirafshoa:
Li-inks tsa khatiso: Ethylcellulose ke motsoako oa bohlokoa mefuteng ea enke ea khatiso. Ho qhibiliha ha eona le thepa ea ho etsa lifilimi ka mefuta e sa tšoaneng ea li-solvents e etsa hore e be e loketseng bakeng sa li-inks tse sebelisoang khatisong ea flexographic le gravure.
Liaparo tsa Lehong: Ethylcellulose e sebelisoa ka mapolanka ho matlafatsa ho khomarela, ho tenyetseha le ho hanyetsa maemo a tikoloho. E thusa ho theha seaparo se tšoarellang le se setle holim'a mapolanka.
5. Sekhomaretsi:
Li-Adhesives tsa Hot Melt: Ethylcellulose e kenngoa ka har'a likhomaretsi tse chesang tse qhibilihisang ho ntlafatsa ho feto-fetoha ha tsona le thepa ea tlamahano. Litefiso tse tlase tsa boima ba limolek'hule tsa ethylcellulose li loketse ka ho khetheha bakeng sa ho etsa likhomaretsi tse chesang tse qhibilihang.
6. Lihlahisoa tsa tlhokomelo ea motho ka mong:
Lihlahisoa tsa Tlhokomelo ea Moriri: Ethylcellulose e fumanoa lihlahisoa tsa tlhokomelo ea moriri tse kang li-gel tsa setaele le li-hairspray. Lintho tsa eona tsa ho etsa lifilimi le tse thibelang metsi li thusa sehlahisoa sa sehlahisoa ho fana ka nako e telele le ho ts'oara.
7. Indasteri ea masela:
Textile Sizing Agent: Ethyl cellulose e sebelisoa e le sesebelisoa sa boholo indastering ea masela ho ntlafatsa matla le botsitso ba masela le masela nakong ea ts'ebetso.
8. Indasteri ea elektroniki:
Li-Electrode Material Binders: Ka indasteri ea lisebelisoa tsa elektroniki, ethylcellulose e sebelisoa e le setlamo sa lisebelisoa tsa elektrode nakong ea tlhahiso ea betri. E thusa ho theha mohaho o tsitsitseng oa electrode.
9. Indasteri ea Oli le Khase:
Li-additives tsa Mekelikeli ea ho Sebetsa: Ethylcellulose e sebelisoa e le tlatsetso ho maro a ho cheka indastering ea oli le khase. E ntlafatsa thepa ea rheological ea maro mme e thusa ho laola sekhahla sa ho kenella nakong ea ts'ebetso ea ho cheka.
Ethylcellulose e sebelisoa haholo liindastering tse fapaneng ho kenyeletsoa meriana, lijo, liphutheloana, masela le lisebelisoa tsa elektroniki ka lebaka la motsoako oa eona o ikhethang oa thepa. Ho feto-fetoha ha ethylcellulose, hammoho le bokhoni ba ho fetola thepa ea eona ka ho kopanya le li-polymers tse ling, ho etsa hore ethylcellulose e be thepa ea bohlokoa bakeng sa litlhoko tse fapaneng tsa indasteri. Ha thekenoloji le lipatlisiso li ntse li tsoela pele, ho sebelisoa ha ethylcellulose ho ka 'na ha eketseha, ho hatisa bohlokoa ba eona mekhoeng ea morao-rao ea indasteri.
