IHydroxypropyl methylcellulose, 28-30% methoxyl, 7-12% hydroxypropyl

Imininingwane ethi “28-30% methoxyl” kanye “7-12% hydroxypropyl” isho izinga lokushintshwaIHydroxypropyl Methylcellulose(HPMC). Lawa manani akhombisa izinga lapho i-polymer yokuqala ye-cellulose ishintshwe ngayo amakhemikhali ngamaqembu e-methoxyl kanye ne-hydroxypropyl.

1. 28-30% Methoxyl:
   • Lokhu kubonisa ukuthi, ngokwesilinganiso, ama-28-30% wamaqembu okuqala e-hydroxyl ku-molecule ye-cellulose athathelwe indawo ngamaqembu e-methoxyl. Amaqembu e-Methoxyl (-OCH3) ethulwa ukwandisa i-hydrophobicity ye-polymer.
2. 7-12% Hydroxypropyl:
   • Lokhu kusho ukuthi, ngokwesilinganiso, ama-7-12% wamaqembu okuqala e-hydroxyl ku-molecule ye-cellulose athathelwe indawo ngamaqembu e-hydroxypropyl. Amaqembu e-Hydroxypropyl (-OCH2CHOHCH3) ethulwa ukuze athuthukise ukuncibilika kwamanzi futhi aguqule ezinye izici ezibonakalayo namakhemikhali ze-polymer.

Izinga lokushintsha lithonya izakhiwo ze-HPMC kanye nokusebenza kwayo ezinhlelweni ezihlukahlukene. Ngokwesibonelo:

• Okuqukethwe okuphezulu kwe-methoxyl ngokuvamile kwandisa i-hydrophobicity ye-polymer, kuthinte ukuncibilika kwayo emanzini nezinye izici.
• Okuqukethwe okuphezulu kwe-hydroxypropyl kungathuthukisa ukuncibilika kwamanzi kanye nezakhiwo zefilimu ze-HPMC.

Lezi zicaciso zibalulekile ekuhlanganiseni i-HPMC ukuze ihlangabezane nezidingo ezithile ezimbonini ezahlukene. Isibonelo, embonini yezemithi, ukukhetha kwebanga le-HPMC elinamadigri athile okushintsha kungase kuthinte amaphrofayela okukhishwa kwezidakamizwa ekwakhiweni kwethebhulethi. Embonini yezokwakha, kungaba nomthelela ekugcineni amanzi kanye nezakhiwo zokunamathela zemikhiqizo esekwe usimende.

Abakhiqizi bakhiqiza amamaki ahlukahlukene e-HPMC enamazinga ahlukene okushintsha ukuze kuhlangatshezwane nezidingo ezahlukahlukene zezinhlelo zokusebenza ezahlukahlukene. Uma usebenzisa i-HPMC ekwakhiweni, kubalulekile kubadidiyeli ukuthi bacabangele ibanga elithile le-HPMC eliqondana nezici ezifiselekayo nezici zokusebenza zohlelo oluhlosiwe.
