I-HPMC polymer

I-HPMC (Hydroxypropyl Methylcellulose) iyi-polymer engeyona i-ionic, encibilika emanzini etholakala ku-cellulose. Isetshenziswa kabanzi emikhakheni ehlukahlukene, kufaka phakathi ezemithi, ukudla, izimonyo, nezinye izimboni. I-HPMC iyi-polymer eguquguqukayo engasetshenziswa ukuguqula izici ezibonakalayo zezinhlelo ezinamanzi, njenge-viscosity, ukungezwani kwendawo, kanye nokunamathela.

I-HPMC iyi-polysaccharide eyakhiwe amayunithi aphindayo ama-molecule e-glucose, axhunywe ndawonye ngamaqembu e-ether kanye ne-methyl. Amaqembu e-ether anikeza i-HPMC ukuncibilika kwayo emanzini, kuyilapho amaqembu e-methyl ehlinzeka i-polymer ngohlamvu olungezona i-ionic. Lokhu kwenza i-HPMC ibe inketho ekahle yezinhlelo zokusebenza ezihlukahlukene, njengoba ingahlakazwa kalula emanzini nakwezinye izincibilikisi ze-polar.

I-HPMC isetshenziswa ezimbonini ezahlukahlukene, okuhlanganisa ezemithi, ukudla, izimonyo, nezinye izimboni. Embonini yezemithi, i-HPMC isetshenziswa njenge-binder, disintegrant, kanye ne-ejenti yokwenza amafilimu. Ibuye isetshenziswe njenge-excipient kumaphilisi nama-capsules, njengoba isiza ukuthuthukisa ukugeleza nokucindezelwa kwezimpushana. Embonini yokudla, i-HPMC isetshenziswa njenge-thickener, stabilizer, kanye ne-emulsifier. Ibuye isetshenziswe embonini yezimonyo njenge-ejenti eyenza amafilimu kanye ne-emulsifier.

I-HPMC iyi-polymer ephephile nesebenzayo engenabo ubuthi futhi engacasuli. Iyakwazi ukubola futhi ihambisana nemvelo. I-HPMC itholakala ngamabanga namafomu ahlukahlukene, njengempushana, ama-granules, nama-flakes. Iyatholakala futhi ngezisindo zamangqamuzana ahlukene, ezingalungiselelwa ukuhlangabezana nezidingo ezithile.

I-HPMC iyisinqumo esihle sezinhlelo zokusebenza eziningi ezahlukene ngenxa yokuguquguquka kwayo, ukuphepha, nokusebenza kahle kwayo. I-polymer engabizi kakhulu futhi ethembekile engasetshenziswa ukuguqula izakhiwo ezibonakalayo zezinhlelo ezinamanzi. I-HPMC iyisithako esibalulekile emikhiqizweni eminingi, futhi ukusetshenziswa kwayo kungenzeka kuqhubeke nokukhula esikhathini esizayo.
