carboxymethyl ethoxy ethyl cellulose

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

Litšobotsi tsa Bohlokoa:

1. Sebopeho sa Lik'hemik'hale: CMEEC e nkiloe ho cellulose, polima ea tlhaho e entsoeng ka likarolo tsa tsoekere. Phetoho e kenyelletsa ho hlahisa lihlopha tsa ethoxy (-C2H5O) le carboxymethyl (-CH2COOH) mokokotlong oa cellulose.
2. Lihlopha tse sebetsang: Ho ba teng ha lihlopha tsa ethoxy, carboxymethyl, le ethyl ester li fana ka thepa e ikhethang ho CMEEC, ho kenyelletsa le ho qhibiliha ka metsing le lihlahisoa tsa lintho tse phelang, bokhoni ba ho etsa lifilimi, le boitšoaro bo botenya bo itšetlehileng ka pH.
3. Motsoako oa Metsi: CMEEC hangata e qhibiliha ka metsing, e etsa litharollo tsa viscous kapa li-dispersions ho latela mahloriso a eona le pH ea mahareng. Lihlopha tsa carboxymethyl li kenya letsoho ho qhibiliheng ha metsi ho CMEEC.
4. Bokhoni ba ho Etsa Lifilimi: CMEEC e ka etsa lifilimi tse hlakileng, tse tenyetsehang ha li omisitsoe, tsa etsa hore e be molemo lits'ebetsong tse kang liphahlo, likhomaretsi le lihlahisoa tsa tlhokomelo ea motho.
5. Thepa ea Thickening le Rheological: CMEEC e sebetsa e le ntho e teteaneng ka har'a litharollo tse nang le metsi, ho eketsa viscosity le ho ntlafatsa botsitso le sebopeho sa metsoako. Boitšoaro ba eona bo botenya bo ka susumetsoa ke lintlha tse kang ho tsepamisa maikutlo, pH, mocheso le sekhahla sa ho kuta.

Lisebelisoa:

1. Liaparo le Lipente: CMEEC e sebelisoa e le sekontiri se teteaneng, se tlamang, le sa ho etsa lifilimi ka har'a litlolo le lipente tse thehiloeng metsing. E ntlafatsa thepa ea rheological, boemo, le ho khomarela lijalo, ha e ntse e fana ka botšepehi le ho tšoarella ha filimi.
2. Likhomaretsi le Li-Sealants: CMEEC e kenyelelitsoe mekhoeng ea sekhomaretsi le ea sealant ho ntlafatsa tackiness, adhesion, le cohesiveness. E tlatselletsa ho viscosity, ho sebetsa, le matla a tlamahano a likhomaretsi le li-sealants.
3. Lihlahisoa tsa Tlhokomelo ea Motho: CMEEC e sebelisoa ho litlolo, matloana, le lihlahisoa tsa tlhokomelo ea motho joalo ka litlolo, litlolo, li-gel le litlolo tsa tlhokomelo ea moriri. E sebetsa e le motenya, stabilizer, emulsifier, le moemeli oa ho etsa lifilimi, e ntlafatsa sebopeho sa sehlahisoa, ho ata, le thepa ea mongobo.
4. Meriana: CMEEC e fumana lits'ebetso mekhoeng ea meriana e kang ho emisoa ka molomo, litlolo tsa topical, le liforomo tsa litekanyetso tse laoloang. E sebetsa e le setlamo, se fetolang viscosity, le filimi ea pele, e nolofatsang phano ea lithethefatsi le botsitso ba foromo ea litekanyetso.
5. Likopo tsa indasteri le tse khethehileng: CMEEC e ka sebelisoa lits'ebetsong tse fapaneng tsa indasteri, ho kenyeletsoa masela, likoahelo tsa pampiri, thepa ea kaho, le lihlahisoa tsa temo, moo ho tenya, ho tlama, le ho etsa lifilimi ho leng molemo.

carboxymethyl ethoxy ethyl cellulose (CMEEC) ke motsoako oa selulose o feto-fetohang o nang le lits'ebetso tse fapaneng tsa ho roala, likhomaretsi, lihlahisoa tsa tlhokomelo ea motho ka mong, meriana le likarolo tse ling tsa indasteri, ka lebaka la ho qhibiliha ha metsi, bokhoni ba ho etsa lifilimi le thepa ea rheological.
