He maha ngā kaiwhakamahi kāore i te aro nui ki te raruraru o te pāmahana o te hydroxypropyl methyl cellulose HPMC gel. I ēnei rā, ko te matotoru o te hydroxypropyl methyl cellulose HPMC te mea e kitea whānuitia ana, engari mō ētahi taiao motuhake me ngā ahumahi motuhake, ko te matotoru anake o te hua e whakaatahia ana. Kāore i te nui, kei raro nei ka whakaurua pototia te pāmahana o te hydroxypropyl methylcellulose HPMC gel.
He hononga tika te ihirangi o te rōpū methoxy ki te nui o te etherification o te cellulose ether. Ka taea te whakarite i te ihirangi o te rōpū methoxy mā te whakahaere i te tātai, te pāmahana tauhohenga me te wā tauhohenga. I taua wā anō, ka pā te nui o te etherification ki te nui o te whakakapinga o te hydroxyethyl, te hydroxypropyl rānei. Nō reira, he kino ake te pupuri wai o te cellulose ether me te pāmahana gel teitei. Me tūhura tēnei tukanga whakaputa, nō reira ehara i te mea nā te iti o te ihirangi methoxy ka iti te utu o te cellulose ether, engari, ka teitei ake te utu.
Ko te nui o te hydroxypropyl methyl cellulose HPMC a QUALICELL he 25%. He mea nui te pāmahana o te gel mō te whakamahinga o te cellulose ether. Ina nui ake te pāmahana o te taiao i te pāmahana gel, ka puta te cellulose ether i roto i te wai, ā, ka ngaro te pupuri wai. Ko te pāmahana o te cellulose ether gel a Qualicell he 65 nekehanga, ā, ka taea te whakatutuki i ngā hiahia o te taiao whakamahi moata me te putty (haunga ngā taiao motuhake). Mena ka hoko koe i te QualiCell HPMC, tena koa whakamōhio mai i mua mena he whakaritenga motuhake āu.
