I muri i te tāpiri i te hydroxypropyl methylcellulose ki ngā rauemi sima, ka taea te whakamātotoru. Ko te nui o te hydroxypropyl methylcellulose e whakatau ana i te hiahia wai o ngā rauemi sima, nō reira ka pā ki te putanga o te moata.
He maha ngā āhuatanga e pā ana ki te matotoru o te hydroxypropyl methylcellulose:
1. Ko te teitei ake o te tohu o te polymerization o te cellulose ether, ko te nui ake o tōna taumaha ngota, ā, ko te teitei ake o te viscosity o te wairewa;
2. Ko te nui ake o te whakaurunga (te kukū rānei) o te cellulose ether, ko te nui ake o te matotoru o tōna wairewa. Heoi, me aro ki te whiriwhiri i te whakaurunga tika i te wā e pania ana kia kore ai e nui rawa te whakaurunga, ka pā ki te mahi a te moata me te raima. āhuatanga;
3. Pērā i te nuinga o ngā wai, ka heke te matotoru o te otinga cellulose ether i te pikinga o te pāmahana, ā, ka nui ake te awe o te pāmahana ki te teitei ake o te kukū o te cellulose ether;
4. He mea hanga noa te wairewa hydroxypropyl methylcellulose hei kirihou rūpahu, ā, he āhuatanga tōna ki te whakangawari i te kutikuti. Ka nui ake te tere kutikuti i te wā whakamātautau, ka iti iho te matotoru.
Nō reira, ka heke te piripono o te moata nā te kaha o waho, he mea pai tēnei mō te hanganga waru o te moata, ka hua ake he pai te mahi me te piripono o te moata i te wā kotahi.
Ka whakaatuhia e te otinga hydroxypropyl methylcellulose ngā āhuatanga wai Newtonian ina tino iti te kukū, ā, ina iti te matotoru. Ina piki te kukū, ka āta whakaatu te otinga i ngā āhuatanga wai rūpahu, ā, ki te teitei ake te kukū, ka kitea te rūpahu.
