Hei karo i te urunga o te makuku ki te pakitara, ka waiho te nui tika o te makuku kia noho ki roto i te moata kia pai ai te mahi a te sima i roto i te wai, ā, ko te tūranga o te hydroxypropyl methyl cellulose i roto i te moata ka rite ki te matotoru, ka pai ake te matotoru o te pupuri wai o te hydroxypropyl methyl cellulose.
Kia nui rawa te makuku o te hydroxypropyl methyl cellulose, ka heke te pupuri wai o te hydroxypropyl methyl cellulose, ā, ka arahi tika atu ki te whai huatanga o te hanganga o te hydroxypropyl methyl cellulose. E mōhio ana hoki tātou ka ngāwari ake te hē o ngā mea, me pupuri tonu tātou kia hou, ka puta he hua ohorere.
Ko te matotoru kitea he tohu nui o te hydroxypropyl methyl cellulose. Ko ngā tikanga ine noa ko te ine matotoru hurihuri, te ine matotoru capillary me te ine matotoru hinga.
I mua, i whakatauhia te hydroxypropyl methyl cellulose mā te ine i te matotoru o te capillary, mā te whakamahi i te Uhnscher viscometer. Ko te otinga ine he otinga wai o te 2, ā, ko te tātai ko: V=Kdt. Ko V te matotoru i roto i ngā hēkona, ko K te pūmau o te viscometer, ko D te mātotoru i te pāmahana pūmau, ā, ko T te wā e pau ana ki te neke mai i runga ki raro o te viscometer i roto i ngā hēkona. He uaua ake tēnei tikanga mahi, ki te mea he rauemi kore e rewa, he ngāwari ki te puta he hapa, he uaua ki te tautuhi i te kounga o te hydroxypropyl methylcellulose.
He raruraru nui te whakarōpūtanga o te kāpia hanga whare. Tuatahi, me whai whakaaro ki te raruraru o ngā rauemi mata mō te whakarōpūtanga o te kāpia hanga whare. Ko te take matua mō te whakarōpūtanga o te kāpia hanga whare ko te kore e hototahi i waenga i te waipiro polyvinyl (PVA) me te hydroxypropyl methylcellulose (HPMC). Ko te take tuarua ko te kore e ranea te wā whakaranu; kei reira anō hoki te kore pai o te mahi whakamātotoru o te kāpia hanga whare.
I roto i ngā kāpia hanga, me whakamahi te hydroxypropyl methylcellulose inamata (HPMC) nā te mea ka marara noa te HPMC i roto i te wai, ā, kāore e tino memeha. Tata ki te 2 meneti, ka piki haere te matotoru o te wai, ka hanga he kōroiti matotoru mārama.
Ka taea te whakamarara tere i ngā hua wairewa wera ki te wai wera i roto i te wai matao, ka memeha haere i roto i te wai wera, ka ngaro atu i roto i te wai wera, ina heke te pāmahana ki tētahi pāmahana, ka puta mārire te matotoru, tae noa ki te hanganga o te kōroiti matotoru mārama. E taunakihia ana te tāpiri i te nui o te Hydroxypropyl methylcellulose (HPMC) ki roto i te kāpia hangahanga mō te 2-4kg.
He pai te pumau matū o te Hydroxypropyl methyl cellulose (HPMC) i roto i te whare piri, he pai te pānga pupuri wai, ā, kāore e pāngia e te huringa PH, ka taea te whakamahi i te matotoru mai i te 100,000 S ki te 200,000 S. Engari i roto i te whakaputanga, kāore e pai ake te matotoru teitei, engari he rerekē te matotoru me te kaha here. He iti ake te matotoru teitei, ā, ko te tikanga he tika te matotoru 100,000S.
