I-Hydroxypropyl Methylcellulose, 28-30% Methoxyl, 7-12% Hydroxypropyll

Imininingwane "28-30% Methoxyl" kanye ne- "7-12% Hydroxypropyl" ibhekisa ezingeni lokufakwa esikhundleniHydroxypropyl methylcellulose(HPMC). Lawa manani akhombisa ukuthi ama-pollulose e-cellulose polymer aguqulwe ngayo ngamakhemikhali namaqembu we-methoxyl ne-hydroxypropyl.

1. 28-30% Methoxyl:
   • Lokhu kukhombisa ukuthi, ngokwesilinganiso, ama-28-30% amaqembu okuqala ama-hydroxyl kuma-molecule we-cellulose afakwe esikhundleni namaqembu we-methoxyl. Amaqembu we-Methoxyl (-Och3) angeniswa ukukhulisa i-hydrophobicity ye-polymer.
2. 7-12% hydroxypropyl:
   • Lokhu kusho lokho, ngokwesilinganiso, ama-7-12% amaqembu okuqala ama-hydroxyl kuma-molecule we-cellulose afakwe esikhundleni samaqembu e-hydroxypropyl. Kwethulwa amaqembu we-Hydroxypropyl (-Och2choHCH3) ukuthuthukisa i-solubity yamanzi futhi kuguqule ezinye izakhiwo zomzimba nezamakhemikhali ze-polymer.

Izinga lokufakwa esikhundleni lithonya izakhiwo ze-HPMC kanye nokusebenza kwayo ezinhlelweni ezahlukahlukene. Ngokwesibonelo:

• Okuqukethwe okuphezulu kwe-methoxyl ngokuvamile kwandisa i-hydrophobicicity ye-polymer, okuthinta i-solubity yayo yamanzi nezinye izakhiwo.
• Okuqukethwe okuphezulu kwe-hydroxypropyl kungathuthukisa i-solubility yamanzi kanye nezakhiwo ezenziwe ngefilimu ze-HPMC.

Lokhu kucaciswa kubalulekile ekutholeni i-HPMC ehambisana nezidingo ezithile ezimbonini ezahlukene. Isibonelo, embonini yezemithi, ukukhethwa kwebanga le-HPMC elinamazinga athile okufaka esikhundleni kungathinta amaphrofayili okukhishwa kwezidakamizwa ekunikezelweni kwethebhulethi. Embonini yezokwakha, kungathinta ukugcinwa kwamanzi kanye nezindawo zokunamathela kwemikhiqizo esekwe kuthusi.

Abakhiqizi bakhiqiza amamaki ahlukahlukene we-HPMC anamazinga ahlukene wokufaka esikhundleni ukuze ahlangabezane nezidingo ezahlukahlukene zezicelo ezahlukahlukene. Lapho usebenzisa i-HPMC ekwakhiweni, kubalulekile ukuthi ama-mulatators abheke ibanga elithile le-HPMC elivumelanisa nezakhiwo ezifunwayo kanye nezimpawu zokusebenza kohlelo lokusebenza okuhlosiwe.
