1. Whakahaere Matatini
Te matotoru teiteihydroxypropyl methylcelluloseKāore e taea te whakaputa i te cellulose tino nui mā te whakakorekore me te whakakapi ki te hauota anake. Heoi, ki te taea te tāuta i tētahi taputapu ine hāora iti ki roto i te ipu, ka taea te whakahaere i te whakaputanga matotoru mā te hangai.
2. Te whakamahinga o ngā āpiha hono
Hei tāpiritanga, i te whakaaro ki te tere whakakapinga o te hauota, ā, i te wā kotahi, he tino pai te ātete hau o te pūnaha, ā, he tino ngāwari ki te whakaputa hua matotoru. He mea nui anō hoki te nui o te whakapūhui o te miro kua parakorehia. Mena kāore tonu e mahi, ka whakamahia te tikanga hononga hydrophobic, ā, ko te momo kaihoko hononga ka whiriwhiria he nui te awe ki te mahi o te hua whakamutunga.
3. Te nui o te hauwaiporoporo
Ka pakaru te cellulose i te toenga o te hāora i roto i te ipu tauhohenga, ā, ka heke te taumaha ngota, engari he iti noa te toenga o te hāora. Mēnā ka honoa anō ngā ngota pakaru, ehara i te mea uaua ki te hanga i te matotoru teitei. Heoi, he hononga tata anō hoki te tere o te mākū o te wai ki te nui o te hydroxypropyl. Ko ētahi wheketere e hiahia ana ki te whakaiti i te utu me te utu, ā, kāore e pai ki te whakanui ake i te nui o te hydroxypropyl, nō reira kāore e taea e te kounga te eke ki te taumata o ngā hua rite.
4. Ētahi atu āhuatanga
He hononga nui tō te tere pupuri wai o te hua ki te hydroxypropyl, engari mō te tukanga tauhohenga katoa, ka whakatau anō hoki i tōna tere pupuri wai, te pānga o te alkaliization, te ōwehenga o te methyl chloride me te propylene oxide, te kukū o te alkali me te wai. Ko te ōwehenga ki te miro kua parakore ka whakatau i te mahi a te hua.
