Hei tētahi o ngā ranunga cellulose ether nui i roto i te moata paura maroke, he maha ngā mahi a te hydroxypropyl methylcellulose i roto i te moata. Ko te mahi nui a te hydroxypropyl methylcellulose i roto i te moata sima ko te pupuri wai me te whakamātotoru. Hei tāpiri, nā tana taunekeneke ki te pūnaha sima, ka taea hoki e ia te whai wāhi atu ki te kukume hau, te whakaroa i te whakatakoto, me te whakapai ake i te kaha o te here kume.
Ko te mahi tino nui o te hydroxypropyl methylcellulose i roto i te moata ko te pupuri wai. Hei ranunga cellulose ether i roto i te moata, ka taea te whakamahi i te hydroxypropyl methylcellulose i roto i te nuinga o ngā hua moata, nā te mea he pupuri wai te nuinga. I te nuinga o te wā, ko te pupuri wai o te hydroxypropyl methylcellulose e pā ana ki tōna matotoru, te nui o te whakakapinga me te rahi o te matūriki.
E whakamahia ana te Hydroxypropyl methylcellulose hei whakamātotoru, ā, e pā ana tōna pānga whakamātotoru ki te nui o te whakakapinga, te rahi o te matūriki, te matotoru me te nui o te whakarerekētanga o te hydroxypropyl methylcellulose. I te nuinga o te wā, ko te teitei ake o te nekehanga whakakapinga me te matotoru o te cellulose ether, ā, ko te iti ake o ngā matūriki, ko te kitea ake o te pānga whakamātotoru.
I roto i te hydroxypropyl methylcellulose, mā te whakaurunga o ngā rōpū methoxy ka whakaiti i te kaha o te mata o te wairewa kei roto ko te hydroxypropyl methylcellulose, kia whai pānga ai te hydroxypropyl methylcellulose ki te hau i runga i te moata sima. Whakauruhia ngā mirumiru hau tika ki roto i te moata, nā te "pānga pōro" o ngā mirumiru hau,
Ka pai ake te mahi hanga o te moata, ā, i te wā anō, ka piki ake te tere o te putanga mai o te moata nā te whakaurunga mai o ngā mirumiru hau. Me whakahaere te nui o te hau e uru ana. Ki te nui rawa te hau e uru ana, ka pā kino ki te kaha o te moata.
Ka whakaroa te Hydroxypropyl methylcellulose i te tukanga whakatō o te sima, ka whakaroa i te tukanga whakatō me te whakapakeke o te sima, ā, ka roa ake te wā whakatuwheratanga o te moata, engari kāore tēnei pānga i te pai mō te moata i ngā rohe makariri.
Hei matū pūmua mekameka roa, ka taea e te hydroxypropyl methylcellulose te whakapai ake i te mahi here ki te papa i muri i te tāpiri atu ki te pūnaha sima i raro i te kaupapa o te pupuri i te makuku i roto i te paru.
Hei whakarāpopototanga, ko te mahi aHPMCKo ngā mahi matua o te moata ko te pupuri wai, te whakamātotoru, te whakaroa i te wā whakatakoto, te kukume hau me te whakapai ake i te kaha o te here kume, me ētahi atu.
