I-Cellulose Ether (HPMC,MC,HEC,EC,HPC,CMC,PAC)

I-cellulose ethers iyiqembu lama-polymers ancibilika emanzini atholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Asetshenziswa kakhulu ezimbonini ezahlukahlukene ukuze ajiye, azinzise, ​​enze amafilimu kanye nezindawo zokugcina amanzi. Nakhu ukubuka okufushane kwezinye izinhlobo ezijwayelekile zama-cellulose ethers:

1. IHydroxypropyl Methylcellulose (HPMC): I-HPMC iyi-ether ye-cellulose esebenza ngezindlela eziningi esetshenziswa kakhulu ekwakhiweni, kwezemithi, ekunakekelweni komuntu siqu, nasezimbonini zokudla. Kwaziwa ngokugcina amanzi kahle kakhulu, ukujiya, kanye nezakhiwo zefilimu. I-HPMC ivamise ukusetshenziswa njenge-thickener, binder, kanye ne-rheology modifier kudaka, izinto zokunamathisela zamathayela, amaphilisi emithi, izimonyo, nemikhiqizo yokudla.
2. I-Methylcellulose (MC): I-MC ifana ne-HPMC kodwa inezinga eliphansi lokufaka esikhundleni samaqembu e-methyl. Isetshenziselwa izinhlelo zokusebenza lapho ukugcinwa kwamanzi okuphansi kanye ne-viscosity kuyadingeka, njengasekwenziweni kwemithi, izixazululo ze-ophthalmic, nanjenge-thickener emikhiqizweni yokudla.
3. IHydroxyethyl Cellulose (HEC): I-HEC enye i-cellulose ether esetshenziswa kabanzi eyaziwa ngokugcina amanzi kahle kakhulu kanye nezakhiwo ezijiyayo. Ivame ukusetshenziswa ezintweni zokwakha ezinjengamapende, okokunamathela, nezinamatheliso, kanye nasemikhiqizweni yokunakekela yomuntu siqu njengama-shampoos, izinto zokuthambisa, nokhilimu.
4. I-Ethyl Cellulose (EC): I-EC i-ether ye-cellulose eshintshwe ngamaqembu e-ethyl. Isetshenziswa kakhulu kwezemithi, okokuhlanganisa, nasezinhlelweni ezikhethekile lapho ukwakhiwa kwefilimu, isithiyo, kanye nezakhiwo zokukhishwa okuqhubekayo kunenzuzo. I-EC ivamise ukusetshenziswa njengento yokwemboza amaphilisi nama-pellets ekwakhiweni kwemithi.
5. I-Hydroxypropyl Cellulose (HPC): I-HPC i-cellulose ether eshintshwe ngamaqembu e-hydroxypropyl. Ivamise ukusetshenziswa njenge-thickener, binder, kanye ne-ejenti yokwakha ifilimu kwezemithi, emikhiqizweni yokunakekelwa komuntu siqu, kanye nasekufakweni kokudla. I-HPC ihlinzeka ngokuncibilika okuhle kakhulu, ukulawulwa kwe-viscosity, nokuzinza ezixazululweni ezinamanzi.
6. I-Carboxymethyl Cellulose (CMC): I-CMC iyi-ether ye-cellulose encibilika emanzini etholakala ku-cellulose nge-carboxymethylation. Isetshenziswa kabanzi njenge-thickener, stabilizer, kanye ne-binder emikhiqizweni yokudla, emithini yemithi, emikhiqizweni yokunakekelwa komuntu siqu, nasezinhlelweni zezimboni. I-CMC yakha izixazululo ezicacile, ezine-viscous futhi ivame ukusetshenziswa njenge-ejenti yokuqina kumasoso, okokugqoka, kanye nokumiswa ngomlomo.
7. I-Polyanionic Cellulose (PAC): I-PAC i-ether ye-cellulose eshintshwe ngamaqembu e-anionic, ngokuvamile i-carboxymethyl noma amaqembu e-phosphonate. Isetshenziswa ngokuyinhloko njengesithasiselo sokulawula ukulahlekelwa uketshezi ekuzimbeni uketshezi lokuhlola uwoyela negesi. I-PAC isiza ekunciphiseni ukulahlekelwa uketshezi, ithuthukise i-viscosity, futhi izinze udaka lokumba ngaphansi kwezimo ezishisa kakhulu nezinomfutho ophezulu.

Lawa ma-cellulose ethers anikezela ngemisebenzi nezinhlelo eziningi ezahlukene kuzo zonke izimboni ezihlukene, okunikela ekusebenzeni, ekuzinzeni, kanye nekhwalithi yemikhiqizo eminingi kanye nokwakheka.
