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

Litlhaloso tsa "28-30% methoxyl" le "7-12% hydroxypropyl" li bua ka tekanyo ea ho nkeloa sebaka hoHydroxypropyl Methylcellulose(HPMC). Litekanyetso tsena li bontša hore na polymer ea pele ea cellulose e fetotsoe hakae ka lik'hemik'hale ka lihlopha tsa methoxyl le hydroxypropyl.

1. 28-30% Methoxyl:
   • Sena se bontša hore, ka karolelano, 28-30% ea lihlopha tsa pele tsa hydroxyl molek'huleng ea cellulose li nketsoe sebaka ke lihlopha tsa methoxyl. Lihlopha tsa methoxyl (-OCH3) li hlahisoa ho eketsa ho se qhibilihe ha polymer.
2. 7-12% Hydroxypropyl:
   • Sena se bolela hore, ka karolelano, 7-12% ea lihlopha tsa hydroxyl tsa pele molek'huleng ea cellulose li nketsoe sebaka ke lihlopha tsa hydroxypropyl. Lihlopha tsa Hydroxypropyl (-OCH2CHOHCH3) li hlahisoa ho ntlafatsa ho qhibiliha ha metsi le ho fetola litšobotsi tse ling tsa 'mele le tsa lik'hemik'hale tsa polymer.

Tekanyo ea ho nkeloa sebaka e susumetsa litšobotsi tsa HPMC le ts'ebetso ea eona lits'ebetsong tse fapaneng. Mohlala:

• Karolelano e phahameng ea methoxyl hangata e eketsa ho se tšabe metsi ha polymer, e leng se amang ho qhibiliha ha eona metsing le thepa e meng.
• Dikahare tse phahameng tsa hydroxypropyl di ka ntlafatsa ho qhibiliha ha metsi le thepa ya ho etsa filimi ya HPMC.

Litlhaloso tsena li bohlokoa haholo ho fetoleng HPMC ho fihlela litlhoko tse itseng indastering e fapaneng. Mohlala, indastering ea meriana, khetho ea sehlopha sa HPMC se nang le maemo a itseng a ho nkeloa sebaka e ka ama liprofaele tsa ho lokolloa ha meriana mefuteng ea matlapa. Indastering ea kaho, e ka ama ho boloka metsi le thepa ea ho khomarela ea lihlahisoa tse thehiloeng samente.

Bahlahisi ba hlahisa mefuta e fapaneng ea HPMC ka maemo a fapaneng a ho nkela sebaka ho fihlela litlhoko tse fapaneng tsa lits'ebetso tse fapaneng. Ha ba sebelisa HPMC mefuteng, ho bohlokoa hore baetsi ba mefuteng ba nahane ka mofuta o itseng oa HPMC o lumellanang le thepa e lakatsehang le litšobotsi tsa ts'ebetso bakeng sa ts'ebeliso e reriloeng.
