I-carboxymethyl ethoxy ethyl cellulose
I-Carboxymethyl ethoxy ethyl cellulose (CMEEC) iwukuphuma kwe-cellulose ether eguquliwe esetshenziswa ezimbonini ezihlukene ngokujiya kwayo, ukusimamisa, ukwenza ifilimu, kanye nezindawo zokugcina amanzi. Ihlanganiswa ngokushintsha i-cellulose amakhemikhali ngokusabela okulandelanayo okubandakanya i-ethoxylation, i-carboxymethylation, ne-ethyl esterification. Nakhu okufingqiwe kwe-CMEEC:
Izimpawu Ezisemqoka:
- Isakhiwo Samakhemikhali: I-CMEEC isuselwa ku-cellulose, i-polymer yemvelo eyakhiwe amayunithi e-glucose. Ukuguqulwa kuhilela ukwethula amaqembu e-ethoxy (-C2H5O) kanye ne-carboxymethyl (-CH2COOH) kumgogodla we-cellulose.
- Amaqembu Asebenzayo: Ukuba khona kwamaqembu e-ethoxy, i-carboxymethyl, kanye ne-ethyl ester kunikeza izakhiwo eziyingqayizivele ku-CMEEC, okuhlanganisa ukuncibilika emanzini nezincibilikisi zemvelo, ikhono lokwenza ifilimu, kanye nokuziphatha kokuqina okuncike ku-pH.
- Ukunyibilika Kwamanzi: I-CMEEC ivamise ukuncibilika emanzini, yakha izixazululo ze-viscous noma ukusabalalisa kuye ngokugxila kwayo kanye ne-pH yendawo. Amaqembu e-carboxymethyl afaka isandla ekuncibilikeni kwamanzi kwe-CMEEC.
- Ikhono Lokwenza Ifilimu: I-CMEEC ingakha amafilimu acacile, aguquguqukayo lapho omisiwe, okwenza abe usizo ezinhlelweni ezifana nezingubo, izinto zokunamathisela, nemikhiqizo yokunakekelwa komuntu siqu.
- Ukuqina kanye Nezakhiwo Zomzimba: I-CMEEC isebenza njenge-ejenti ejiyayo ezixazululweni ezinamanzi, ikhulisa i-viscosity futhi ithuthukise ukuzinza nokuthungwa kwezinto ezakhiwe. Ukuqina kwayo kungase kuthonywe izici ezifana nokugxilisa ingqondo, i-pH, izinga lokushisa, nezinga lokugunda.
Izicelo:
- I-Coatings and Paints: I-CMEEC isetshenziswa njenge-thickener, binder, kanye ne-ejenti yokwakha ifilimu kuma-coatings namapende asekelwe emanzini. Ithuthukisa izakhiwo ze-rheological, izinga, kanye nokunamathela kwezingubo ngenkathi inikeza ubuqotho befilimu nokuqina.
- Ama-Adhesives nama-Sealants: I-CMEEC ifakwe ekwakhiweni okunamathelayo kanye ne-sealant ukuze kuthuthukiswe i-tackiness, ukunamathela, nokubumbana. Inikela ku-viscosity, ukusebenza, namandla okubopha ama-adhesives nama-sealants.
- Imikhiqizo Yokunakekelwa Komuntu Siqu: I-CMEEC isetshenziselwa izimonyo, izinto zangasese, kanye nemikhiqizo yokunakekelwa komuntu siqu efana nokhilimu, izinto zokuthambisa, amajeli, kanye nokwakheka kwezinwele. Isebenza njenge-thickener, stabilizer, emulsifier, kanye ne-ejenti yokwakha ifilimu, ithuthukisa ukuthungwa komkhiqizo, ukusabalala, kanye nezakhiwo zokuswakama.
- Ezemithi: I-CMEEC ithola izinhlelo zokusebenza ekwakhiweni kwemithi njengokumiswa ngomlomo, okhilimu bama-topical, namafomu omthamo wokukhishwa olawulwayo. Isebenza njenge-binder, i-viscosity modifier, kanye nefilimu yangaphambili, esiza ukulethwa kwezidakamizwa nokuzinza kwefomu lomthamo.
- Izicelo Zezimboni Nezikhethekile: I-CMEEC ingasetshenziswa ezinhlelweni ezihlukene zezimboni, okuhlanganisa izindwangu, izimbotshana zephepha, izinto zokwakha, kanye nemikhiqizo yezolimo, lapho izakhiwo zayo zokujiya, ukubopha, nokwenza amafilimu zinenzuzo.
I-carboxymethyl ethoxy ethyl cellulose (CMEEC) iwumphumela we-cellulose oguquguqukayo osetshenziswa ngezindlela ezahlukahlukene embotsheni, ezintweni ezinamathelayo, emikhiqizweni yokunakekela umuntu, ezemithi, neminye imikhakha yezimboni, ngenxa yokuncibilika kwayo emanzini, ikhono lokwenza ifilimu, kanye nezakhiwo ze-rheological.
