carboxymethyl ethoxy ethyl cellulose

Carboxymethyl ethoxy ethyl cellulose (CMEEC) ke motsoako o fetotsoeng oa ether oa cellulose o sebelisoang liindastering tse fapaneng bakeng sa ho tenya ha eona, ho tsitsisa, ho etsa filimi le ho boloka metsi. E hlahisoa ka ho fetola cellulose ka lik'hemik'hale ka liketso tse latellanang tse kenyelletsang ethoxylation, carboxymethylation le esterification ea ethyl. Mona ke kakaretso e khutšoanyane ea CMEEC:

Litšobotsi tsa Bohlokoa:

1. Sebopeho sa Lik'hemik'hale: CMEEC e nkiloe ho cellulose, polymer ea tlhaho e entsoeng ka li-unit tsa glucose. Phetoho ena e kenyelletsa ho hlahisa lihlopha tsa ethoxy (-C2H5O) le carboxymethyl (-CH2COOH) mokokotlong oa cellulose.
2. Lihlopha tse Sebetsang: Boteng ba lihlopha tsa ethoxy, carboxymethyl, le ethyl ester bo fana ka thepa e ikhethang ho CMEEC, ho kenyeletsoa ho qhibiliha metsing le li-solvents tsa tlhaho, bokhoni ba ho etsa filimi, le boitšoaro ba ho teteana bo itšetlehileng ka pH.
3. Ho qhibiliha ha metsi: CMEEC hangata e qhibiliha ka metsing, e etsa ditharollo tse hlabang kapa tse hasaneng ho latela mahloriso a yona le pH ya sekgahla. Dihlopha tsa carboxymethyl di kenya letsoho ho qhibiliheng ha metsi ha CMEEC.
4. Bokhoni ba ho Etsa Filimi: CMEEC e ka etsa lifilimi tse hlakileng, tse tenyetsehang ha e omisitsoe, e leng se etsang hore e be molemo lits'ebetsong tse kang lipente, likhomaretsi le lihlahisoa tsa tlhokomelo ea motho ka mong.
5. Matlotlo a ho Tetefatsa le a Rheological: CMEEC e sebetsa e le moemeli oa ho tebisa litharollong tsa metsi, e eketsa viscosity le ho ntlafatsa botsitso le sebopeho sa metsoako. Boitšoaro ba eona ba ho tebisa bo ka susumetsoa ke lintlha tse kang mahloriso, pH, mocheso le sekhahla sa ho shear.

Likopo:

1. Lipente le Lipente: CMEEC e sebelisoa e le sesebelisoa sa ho tenya, ho kopanya le ho etsa filimi lipenteng le lipenteng tse thehiloeng metsing. E ntlafatsa thepa ea rheological, ho leka-lekanya le ho khomarela ha lipente ha e ntse e fana ka botšepehi le ho tšoarella ha filimi.
2. Likhomaretsi le Litiiso: CMEEC e kenyelelitsoe mefuteng ea likhomaretsi le litiiso ho ntlafatsa ho tiea, ho khomarela le ho momahana. E tlatsetsa ho viscous, ho sebetsa hantle le matla a ho kopanya likhomaretsi le litiiso.
3. Lihlahisoa tsa Tlhokomelo ea Motho ka Mong: CMEEC e sebelisoa litlolong, linthong tsa ho hlapa le lihlahisoa tsa tlhokomelo ea motho ka mong tse kang litlolo, litlolo, li-gel le mekhoa ea tlhokomelo ea moriri. E sebetsa e le sesebelisoa se matlafatsang, se tsitsisang, se kopanyang le se etsang filimi, se ntlafatsang sebopeho sa sehlahisoa, ho hasana ha sona le thepa ea ho nolofatsa mongobo.
4. Meriana: CMEEC e fumana lits'ebeliso mefuteng ea meriana e kang li-suspension tse nooang, litlolo tse tlotsoang letlalong, le mefuta ea litekanyetso tse laoloang. E sebetsa e le sesebelisoa sa ho kopanya, ho fetola viscosity, le ho etsa filimi, e nolofalletsang ho fana ka meriana le botsitso ba foromo ea litekanyetso.
5. Ditshebediso tsa Diindasteri le tse Ikgethang: CMEEC e ka sebediswa ditshebedisong tse fapaneng tsa diindasteri, ho kenyeletswa masela, dikobo tsa pampiri, thepa ya kaho le dihlahiswa tsa temo, moo thepa ya yona ya ho teteana, ho tlama le ho etsa filimi e leng molemo.

carboxymethyl ethoxy ethyl cellulose (CMEEC) ke setlolo se nang le diphetoho tse ngata se nang le ditshebediso tse fapaneng ho dikoahelo, dikhomaretsi, dihlahiswa tsa tlhokomelo ya motho ka mong, meriana le mafapha a mang a indasteri, ka lebaka la ho qhibiliha ha yona ka metsi, bokgoni ba ho etsa filimi, le thepa ya rheological.
