Ko te tūranga nui o te HPMC i roto i te moata mākū-whakaranu ko ngā āhuatanga e toru e whai ake nei:
1. He tino pai te kaha pupuri wai o te HPMC.
2. Te awe o te HPMC ki te ōritetanga me te thixotropy o te moata mākū-ranu.
3. Te taunekeneke i waenga i te HPMC me te sima.
He mahi nui te pupuri wai o te HPMC, ā, he mahi anō hoki e aro nui ana te nuinga o ngā kaihanga moata ranunga mākū ki tēnei.
Ko te pānga pupuri wai o te HPMC e whakawhirinaki ana ki te tere mimiti wai o te paparanga turanga, te hanganga o te moata, te matotoru o te paparanga o te moata, te hiahia wai o te moata, me te wā whakatakoto o te rauemi whakatakoto.
HPMC – te pupuri wai
Ka teitei ake te pāmahana o te HPMC, ka pai ake te pupuri wai.
Ko ngā mea e pā ana ki te pupuri wai o te moata mākū-ranu ko te matotoru o te HPMC, te nui o te tāpiri, te matotoru o te matūriki me te pāmahana whakamahinga.
He mea nui te matotoru mō te mahi a te HPMC. Mō te hua kotahi, he rerekē rawa ngā hua matotoru i inehia mā ngā tikanga rerekē, ā, ko ētahi ka rua te rerekētanga. Nō reira, ina whakatauritehia ngā matotoru, me mahi i waenga i ngā tikanga whakamātautau kotahi, tae atu ki te pāmahana, te porowhita, me ētahi atu. I te nuinga o te wā, ko te teitei ake o te matotoru, ko te pai ake o te pānga pupuri wai.
Heoi, ko te teitei ake o te matotoru me te nui ake o te taumaha ngota o te HPMC, ko te whakahekenga o tōna wairewa ka pā kino ki te kaha me te mahi hanga o te moata. Ko te teitei ake o te matotoru, ko te kitea ake o te pānga matotoru o te moata, engari kāore i te ōrite. Ko te teitei ake o te matotoru, ko te matotoru ake o te moata mākū, e whakaatu ana i te piri ki te waru i te wā hanga me te piri nui ki te papa. Heoi, he iti noa te pānga o te HPMC ki te whakapai ake i te kaha hanganga o te moata mākū tonu, e tohu ana kāore i te kitea te mahi ārai-totoka. I tetahi atu taha, ko ētahi HPMC whakarerekētia me te matotoru reo me te iti he tino pai ki te whakapai ake i te kaha hanganga o te moata mākū.
He pānga anō hoki te pai o te HPMC ki tōna pupuri wai. I te nuinga o te wā, mō te HPMC he rite te matotoru engari he rerekē te pai, ka pai ake te pānga pupuri wai o te HPMC i raro i te nui tāpiri ōrite.
