Ko te parakore o te hydroxypropyl methylcellulose i roto i te moata whakamahana whare me te paura putty e pā tika ana ki te kounga o te hanganga hangarau, nō reira he aha ngā āhuatanga e pā ana ki te parakore o te hydroxypropyl methylcellulose? Tukua ahau kia whakautu i tēnei pātai māu.
I roto i te tukanga whakaputa o te hydroxypropyl methylcellulose, ka pakaru te hydroxypropyl methylcellulose i roto i te tauhohenga, ā, ka whakaitihia te taumaha ngota, engari he iti noa te toenga o te hāora, mena kāore i te tino uaua ki te hono anō i ngā ngota pakaru. He aituā. Ko te nui o te wai mākū e pā ana ki te nui o te hydroxypropyl. Ko ētahi wheketere e hiahia ana ki te whakaiti i te utu me te utu, engari kāore e hiahia 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 o tāwāhi.
He hononga nui anō hoki te tere pupuri wai o te hydroxypropyl methylcellulose ki te hydroxypropyl, ā, mō te tukanga tauhohenga katoa, ka whakatau anō hoki te hydroxypropyl i te tere pupuri wai o te hydroxypropyl methylcellulose. Ko te pānga o te alkaliization, te ōwehenga o te methyl chloride me te propylene oxide, te kukū o te alkali me te ōwehenga o te wai ki te miro kua parakore, koinei katoa ngā mea e whakatau ana i te mahi a te hua.
Ko te kounga o ngā rauemi mata, te pānga o te whakapūkara, te whakahaere ōwehenga o te tukanga, te ōwehenga o ngā whakarewa me te pānga o te whakakorekoretanga e whakatau ana i te kounga o te hydroxypropyl methylcellulose, ā, ko ētahi hydroxypropyl methylcellulose ka hangaia kia rewa. I muri mai, he kapua, he rite ki te tāpiri miraka, ko ētahi he mā miraka, ko ētahi he kōwhai, ā, ko ētahi he mārama, he mārama. Ki te hiahia koe ki te whakaoti, whakatikatikahia mai i ngā tohu o runga ake nei. I ētahi wā ka pā kino te waikawa acetic ki te whakawhiti mārama. He pai ake te whakamahi i te waikawa acetic i muri i te waimehatanga. Ko te awe nui ko te rite o te whakaoho o te tauhohenga me te pumau o te ōwehenga pūnaha (he makuku ētahi rauemi, ā, he koretake te ihirangi, pērā i te hangarua i ngā whakarewa). Inaa, he maha ngā āhuatanga e whai wāhi ana. Me te pumau o ngā taputapu me te mahi a ngā kaiwhakahaere kua whakangungua pai, me tino pumau ngā hua ka puta. Kaua te whakawhiti mārama e neke ake i te awhe o te ±2%, ā, me whakahaere pai te ōritetanga whakakapinga o ngā rōpū whakakapinga. Engari i te ōritetanga, he pai te whakawhiti mārama.
