Ko te HPMC（CAS:9004-65-3）, hei tāpiri e whakamahia whānuitia ana i roto i te ao o ngā rauemi hanga, e whakamahia nuitia ana mō te pupuri wai, te whakamātotoru me te whakapai ake i te mahi o te hua kua oti. Ko te tere pupuri wai tētahi o ngā tohu matua ina whiriwhiri koe i te HPMC kounga teitei, nō reira me titiro tata atu tātou ki ngā āhuatanga e pā ana ki te tere pupuri wai o te HPMC.
1. Ko te horopeta o te HPMC, me tōna mahi pupuri wai, he rite tonu ki te nui i tāpirihia. Ko te nui o te HPMC e whakamahia ana i roto i ngā rauemi hanga i te mākete he rerekē i runga i te kounga. Ko te tikanga ka tāpirihia ki roto i ngā mea pēnei i te here, te parai, te moata ārai-pakaru, me ētahi atu. Ko te nui tāpiri whānui ko te 2~2.5 KG /MT, ko te nui tāpiri o te putty me ētahi atu kei waenga i te 2~4.5 KG/MT, ko te kāpia taera kei waenga i te 3.5~4 KG/MT, ā, ko te nui o te grout taera ko te 0.3 ~1 KG/MT e ai ki ngā tikanga hanga rerekē, te whānui o te āputa me te matotoru o te paru, ko te moata whakataurite-ake kei waenga i te 0.2~0.6 KG/MT, ā, ko te ETICS kei waenga i te 4~7 KG/MT. I roto i tēnei awhe, ki te nui ake te HPMC e tāpirihia ana, ka pai ake te mahi pupuri wai.
2. Te pānga o te taiao hanga. Ka pā te haumākū o te hau, te pāmahana, te pēhanga hau, te tere o te hau me ētahi atu āhuatanga ki te tere memeha o te wai i roto i te moata sima me ngā hua e hangai ana ki te gypsum. I ngā wā rerekē me ngā rohe rerekē, ka rerekē te tere pupuri wai o te hua kotahi, engari i te nuinga o te wā, he nui te pānga o te pāmahana ki te tere pupuri wai, nō reira he tirohanga kei te mākete: Ko te HPMC me te pāmahana tiēre teitei ake he hua kounga teitei me te tere pupuri wai teitei.
3. Te tukanga whakaputa me te matotoru o te cellulose ether -HPMC. He ōrite te tohatoha o ngā rōpū methoxy me te hydroxypropoxy i te mekameka ngota cellulose, ka taea ai te whakanui ake i te hononga o ngā ngota hāora ki ngā hononga hydroxyl me te ether ki te wai. Mā te kaha o te here hauwai ka noho te wai kore utu hei wai here, ā, ka whakahaere pai i te mimiti o te wai, ka tutuki ai te pupuri wai nui.
Ina piki te matotoru o te HPMC, ka piki anō hoki te tere pupuri wai, ka tae te matotoru ki tētahi taumata, ka piki te tere pupuri wai. He papatahi te āhua. He tirohanga whānui ngāwari. Ka pāngia te mahi pupuri wai o te HPMC e ngā āhuatanga katoa. Kāore e taea te whiriwhiri i runga i tētahi tohu kotahi.
