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 mea he maakahu ma te waiu, he kowhatu, he kowhai, ko etahi he 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.
