Ko te poke o te hydroxypropyl methylcellulose i roto i te whakakakara whakairo me te paura nui e pa ana ki te kounga o te hangahanga miihini, na he aha nga mea e pa ana ki te poke o te hydroxypropyl? Me whakahoki e au tenei patai mo koe.
I roto i te mahinga whakaputa o te hydroxypropyl methylcellulose, ko te hāora toenga i roto i te kaiwhakamaori ka whakahekehia te taumaha o te hydroxypropyl, engari ko te toenga o te hāora, engari kaore i tino uaua ki te hono i te parekura. Ko te reanga nui o te pueru wai nui rawa atu he nui ki te mahi i te kiko o te hydroxypropyl. Ko etahi o nga wheketere e hiahia ana ki te whakaheke i te utu me te utu, engari kaore e hiahia ki te whakapiki i te kiko o te hydroxypropyl, na reira kaore e taea te kounga te tae ki te taumata o nga hua rereke.
Ko te reanga pupuri wai o te hydroxypropyl methylcellolose hoki he hononga nui ki te hydroxypropyl, a mo te katoa o te tauhohenga, ka whakatau ano hoki te hydroxypropyl te reanga pupuri wai o te hydroxypropyl. Ko te hua o te rewa, te ōwehenga o te methyl chloride me te propolene oxide, te kukume o te alkali me te paanga o te wai ki te whakarite i te miro o te hua.
Ko te kounga o nga rauemi mata, te hua o te whakarewatanga, te paanga o te whakarewa, te paanga o te whakaraeraetanga me te whakakotahitanga o te hydroxyproplolose, ka tiaho te ahua Ko te waiu, ko etahi he ma milky, ko etahi he kowhai, ko etahi he marama me te marama. Mena kei te hiahia koe ki te whakaoti, whakatika mai i nga waahanga o runga ake nei. I etahi wa ka tino pa te waikawa acetic ki te whakawhiti maama. He pai ake te whakamahi i te waikawa acetic i muri i te waikawa. Ko te mana nui ko te whakaohooho i te ohorere o te punaha me te mea he makuku o te punaha (ko etahi o nga makuku me nga mea whakarewa, penei i te whakarewatanga tuhi). Ina hoki, he maha nga ahuatanga kei te takaro. Ma te pumau o nga taputapu me te whakahaere o nga kaiwhakahaere kua oti te whakangungu, me tino pumau nga hua. Ko te Whakawhitiwhiti Maama e kore e neke atu i te waahanga o te ± 2%, me te whakakotahitanga o te whakakapinga o nga roopu whakahihiri me tino whakahaere. Engari ki te whakakotahi, ka tino pai te whakawhiti marama.
