HPMC gel osakaniza kutentha

Ogwiritsa ntchito ambiri salabadira vuto la kutentha kwa gel osakaniza a hydroxypropyl methyl cellulose HPMC. Masiku ano, hydroxypropyl methyl cellulose HPMC nthawi zambiri imasiyanitsidwa ndi mamasukidwe akayendedwe, koma m'malo ena apadera ndi mafakitale apadera, kukhuthala kokha kwa mankhwalawa kumawonetsedwa. Zosakwanira, zotsatirazi zikuwonetsa mwachidule kutentha kwa gel osakaniza a hydroxypropyl methylcellulose HPMC.

Zomwe zili mu gulu la methoxy zimagwirizana mwachindunji ndi mlingo wa etherification wa cellulose ether. Zomwe zili m'gulu la methoxy zitha kusinthidwa ndikuwongolera chilinganizo, kutentha kwamachitidwe ndi nthawi yochitira. Pa nthawi yomweyo, mlingo wa etherification zimakhudza mlingo wa m'malo hydroxyethyl kapena hydroxypropyl. Chifukwa chake, kusungidwa kwamadzi kwa cellulose ether yokhala ndi kutentha kwa gel osakaniza kumakhala koyipa pang'ono. Njira yopangirayi iyenera kufufuzidwa, kotero sichifukwa chakuti zinthu za methoxy ndizochepa, mtengo wa cellulose ether ndi wotsika, m'malo mwake, mtengo udzakhala wapamwamba.

QUALICELL's hydroxypropyl methyl cellulose HPMC hydroxypropyl ndi 25%. Kutentha kwa gel osakaniza ndi mfundo yofunika kwambiri pakugwiritsa ntchito cellulose ether. Kutentha kozungulira kukakhala kopitilira kutentha kwa gel, cellulose ether imatuluka m'madzi ndikusiya kusunga madzi.
