carboxymethyl ethoxy ethyl cellulose

I-Carboxymethyl ethoxy ethyl cellulose (CMEEC) iyisisulu esiguquliwe esiguqulwa esisetshenziswa ezimbonini ezahlukahlukene ngokuqina kwayo, ukuzinza, amafilimu okugcina amanzi. Ihlelwe ngokuguqula ngamakhemikhali ukuguqula iselula ngokuphendula okulandelanayo okubandakanya i-ethoxylation, i-carboxymethylity, kanye ne-ethyl asserication. Nasi umbono omfushane we-CMEEC:

Izici ezibalulekile:

1. Isakhiwo samakhemikhali: I-CMEEC isuselwa ku-cellulose, i-polymer yemvelo eyakhiwe ngamayunithi we-glucose. Ukuguqulwa kuhlanganisa ukwethula i-Ephoxy (-c2h5o) kanye ne-carboxymethyl (-ch2cooh) amaqembu e-cellulose backbone.
2. Amaqembu asebenzayo: Ukuba khona kwe-ethoxy, i-carboxymethyl, kanye namaqembu e-ETHEL Ester aqukethe i-solubity emanzini kanye ne-organic solvents, amandla ancike emfihlakalweni.
3. I-Solubinity yamanzi: I-CMEEC imvamisa incibilika emanzini, yakha izixazululo ze-viscous noma ukuhlukaniswa ngokuya ngokuhlushwa kwayo kanye ne-PH ye-Medium. Amaqembu e-carboxymethyl anikela nge-solubility yamanzi ye-CMEEC.
4. Ikhono elenziwe ngefilimu: I-CMEEC ingakha amafilimu acacile, aguqukayo lapho omisiwe, okwenza kube lusizo kuzinhlelo zokusebenza ezinjengezembatho, ukunamathela, nemikhiqizo yokunakekelwa komuntu siqu.
5. Ukuqina kanye nezakhiwo ze-Rheological: I-CMEEC isebenza njenge-ejenti yokuqina ezixazululweni zamanzi, ezandayo zokuvuleka kanye nokwenza ngcono ukuqina kanye nokuthungwa kokwakheka. Ukuziphatha kwalo okukhuphuka kungathonywa yizinto ezifana nokuhlushwa, i-pH, lokushisa, nezinga le-vear.

Izicelo:

1. I-Coatings nopende: I-CMEEC isetshenziswa njengesikhudlwana, i-Binder, ne-ejenti eyakha amafilimu ezindaweni zokugqoka ezisuselwa emanzini. Kuthuthukisa izakhiwo ze-mboyamoological, ukulinganisa, kanye nokunamathela kwezimbozo ngenkathi kuhlinzeka ubuqotho befilimu nokuqina.
2. Adhesives kanye nama-sealants: I-CMEEC ifakwa kwimivimbo yokunamathela futhi ye-sealant ukuthuthukisa ukubekezelela, ukunamathela kanye nokubumbana. Kunomthelela ekuboneni, ukusebenziseka kanye namandla abopha ama-adhesives kanye nama-sealants.
3. Imikhiqizo yokunakekelwa komuntu siqu: I-CMEEC isetshenziswa kwizimonyo, izindlu zangasese, nemikhiqizo yokunakekelwa komuntu siqu efana nokhilimu, ama-lotion, ama-gels, kanye nokwakheka kwezinwele. Isebenza njengomkhulu, i-Stabilizer, emulsifier, kanye ne-ejenti eyakha amafilimu, ukuthuthukisa ukuthungwa komkhiqizo, ukusakazeka kanye nezakhiwo ezinomswakama.
4. I-Pharmaceuticals: I-CMEEC ithola izinhlelo zokusebenza ezakhiweni semithi ezinjengokumiswa komlomo, okhilimu abaphezulu, nezindlela zokukhishwa kwezithonjana ezilawulwayo. Isebenza njengesi-binder, i-viscosity modififier, kanye nefilimu yangaphambili, lula ukulethwa kwezidakamizwa kanye nemithamo yokuqina kwefomu.
5. Izicelo zezimboni nezezikhakha ezikhethekile: I-CMEEC ingahle isetshenziswe ezinhlelweni ezahlukahlukene zezimboni, kufaka phakathi izindwangu, izimbotshana zamaphepha, izinto zokwakha, kanye nemikhiqizo yezolimo, lapho kuzuzisa khona.

I-Carboxymethyl ethyly ethyl cellulose (CMEEC) iyisisulu esiguquguqukayo esisezingeni elihlukile ekuhlolweni, ezinamathelayo, imikhiqizo yokunakekelwa komuntu, neminye imikhakha yayo yezimboni, ikhono le-mboleko, kanye nezakhiwo ze-Rheological.
