I-Hypromellose 2208 kanye ne-2910

I-Hypromellose, eyaziwa nangokuthi i-hydroxypropyl methylcellulose (HPMC), iyi-ether ye-cellulose engenabuthi futhi engeyona i-ionic esetshenziswa kwizinhlelo zokusebenza ezahlukahlukene, okuhlanganisa imithi, izimonyo, nemikhiqizo yokudla. I-HPMC itholakala ebangeni lamabanga, okuhlanganisa i-Hypromellose 2208 kanye ne-2910, enezakhiwo nezindlela ezihlukene zokusebenza.

I-Hypromellose 2208 iyibanga eliphansi le-viscosity le-HPMC elivame ukusetshenziswa njenge-binder, thickener, kanye nefilimu yangaphambili kwezemithi. Ivamise ukusetshenziswa ezimbotsheni zamathebulethi, lapho ihlinzeka ngobushelelezi, indawo ecwebezelayo futhi ithuthukisa ukuqina kwethebhulethi. I-Hypromellose 2208 iphinde isetshenziswe ekwakhiweni kwe-ophthalmic, lapho isebenza njenge-lubricant futhi ithuthukisa i-viscosity yokwakheka.

I-Hypromellose 2910 iyibanga eliphakeme le-viscosity le-HPMC elisetshenziswa njenge-thickener, binder, kanye ne-emulsifier kuzinhlelo zokusebenza eziningi. Kwezemithi, ivamise ukusetshenziswa njenge-ejenti ekhishwa njalo, njengoba ikhulula kancane isithako esisebenzayo ngokuhamba kwesikhathi. I-Hypromellose 2910 nayo isetshenziselwa izimonyo, lapho inikeza umphumela wokuqina, ithuthukisa ukuzinza kwe-emulsion, futhi ithuthukise ukuthungwa komkhiqizo.

Kafushane, i-Hypromellose 2208 kanye ne-2910 amamaki amabili e-HPMC anezakhiwo nezinhlelo zokusebenza ezahlukene. I-Hypromellose 2208 iyibanga eliphansi le-viscosity elisetshenziswa kwezokwelapha, kuyilapho i-Hypromellose 2910 iyibanga eliphakeme le-viscosity elisetshenziswa kwezokwelapha, izimonyo, nezinye izinhlelo zokusebenza.
