Focus on Cellulose ethers

Izakhiwo ze-Hydroxyethyl methyl cellulose

Isici 11 (1-6)

01
Ukunyibilika:
Iyancibilika emanzini nakwezinye izincibilikisi eziphilayo. Ingancibilika emanzini abandayo. Ukugxila kwayo okuphezulu kunqunywa kuphela yi-viscosity. I-solubility iyashintsha nge-viscosity. I-viscosity ephansi, i-solubility enkulu.

02
Ukumelana nosawoti:
Umkhiqizo uyi-ether ye-cellulose engeyona i-ionic futhi ayiyona i-polyelectrolyte, ngakho-ke uzinzile kusisombululo samanzi lapho kukhona usawoti wensimbi noma ama-electrolyte aphilayo, kodwa ukwengezwa ngokweqile kwama-electrolyte kungabangela i-gelation kanye nemvula.

03
Umsebenzi ongaphezulu:
Ngenxa yomsebenzi osebenzayo wesisombululo se-aqueous, ingasetshenziswa njenge-ejenti yokuzivikela ye-colloid, i-emulsifier kanye ne-dispersant.

04
Ijeli Eshisayo:
Lapho isixazululo esinamanzi somkhiqizo sishiselwa ezingeni lokushisa elithile, siyashintshashintsha sibe yi-opaque, ama-gel, futhi sakhe imvula, kodwa lapho sipholiswa ngokuqhubekayo, sibuyela esimweni sokuqala sesixazululo, futhi izinga lokushisa lapho i-gelation enjalo kanye nemvula kwenzeka kakhulu kuncike kakhulu. kumafutha abo. , usizo lokumisa okwesikhashana, i-colloid evikelayo, i-emulsifier, njll.

05
I-metabolism:
I-metabolically inert nephunga elimnandi nephunga elimnandi, asetshenziswa kakhulu ekudleni nasemthini ngoba awagayelwanga futhi anephunga eliphansi nephunga.

06
Ukumelana nesikhutha:
Inekhono elihle le-antifungal kanye nokuzinza okuhle kwe-viscosity ngesikhathi sokugcina isikhathi eside.
