I-HYDROXYPOPLL Methylcelceltulose

Inkcazo "28-30% ye-Accapyyl" kunye "ne-7-12% hydroxypropyl" Jonga inqanaba lokufaka endaweniHydroxypropyl methylcelceluplose(I-HPMC). La maxabiso abonisa ubungakanani besipoloy se-selselose ye-selselose ye-scoymes sele iguqulwe nge-scocxyl kunye namaqela e-hydroxypropyl.

1. I-28-30% ye-PAXXYL:
   • Oku kubonisa ukuba, ngokomyinge, i-28-30% yamaqela e-hydroxyl ye-hydroxyl kwimolekyuli ye-selselose iye yafakwa ngamaqela e-APUCISSYL. I-Accopxyl amaqela (-och3) aziswa ukwandisa i-hydrophobicity ye-polymer.
2. I-7-12% hydroxypropy:
   • Oku kubonisa ukuba, ngokomyinge, i-7-12% ye-hydroxyl yamaqela e-hydroxyl kwi-molecule ye-selselose iye yabekwa endaweni yamaqela e-hydroxypropy. Amaqela e-hydroxypropyl

Iqondo lokufakela ifuthe kwipropathi ye-HPMC kunye nentsebenzo yayo kwizicelo ezahlukeneyo. Umzekelo:

• Umxholo ophezulu we-playxyl ngokubanzi ukonyusa i-pollyrophobicity ye-polymer, echaphazela ukonakala kwamanzi kunye nezinye iipropathi.
• Umxholo we-hydroxypropyl ephezulu unokuphucula ukubenzela amanzi kunye neempawu zokwenza ifilimu ze-HPMC.

Ezi ngcaciso zibaluleke kakhulu ekulungelelaniseni i-HPMC yokufezekisa iimfuno ezithile kumashishini ahlukeneyo. Umzekelo, kumzi-mveliso wamayeza, ukhetho lweBanga le-HPMC enamanqanaba athile okufaka i-fake inokuthi ichaphazele iiprofayili zeziyobisi kwifom yetafile. Kumzi-mveliso wokwakha, kunokuba nefuthe ekugcinweni kwamanzi kunye nokubulala kwemfuyo yeemveliso ezisekwe kwisamente.

Abavelisi bavelisa amabanga ahlukeneyo i-HPMC enamanqanaba ahlukeneyo okufaka endaweni yokuhlangabezana nezidingo ezahlukeneyo zezicelo ezahlukeneyo. Xa usebenzisa i-HPMC ekuqulunqweni, kubalulekile ukuba iifomula ukuqwalasela inqanaba elithile le-HPMC ehambelana neepropathi ezinqwenelekayo kunye neempawu zentsebenzo kwisicelo esicetywayo.
