Ko te ma o te hydroxypropyl methylcellulose i roto i te hanga moata whakamatao me te paura putty ka pa ki te kounga o te hanga miihini, na he aha nga mea e pa ana ki te ma o te hydroxypropyl methylcellulose? Tukua ahau ki te whakautu i tenei patai mo koe.
I roto i te tukanga whakaputa o te hydroxypropyl methylcellulose, ko te toenga o te hāora i roto i te reactor ka meinga te kino o te hydroxypropyl methylcellulose me te whakaiti i te taumaha ngota, engari he iti te toenga o te hāora, i te mea kaore he tino uaua ki te hono ano i nga ngota ngota kua pakaru. Ko te nui o te reiti waipuna he nui te mahi ki te ihirangi o te hydroxypropyl. Ko etahi o nga wheketere e hiahia ana ki te whakaiti i te utu me te utu, engari kaore e hiahia ki te whakanui ake i nga ihirangi o te hydroxypropyl, na reira kaore e taea e te kounga te eke ki te taumata o nga hua o waho.
Ko te tere o te pupuri wai o te hydroxypropyl methylcellulose he hononga nui ki te hydroxypropyl, a mo te katoa o te tukanga tauhohenga, ka whakatauhia e te hydroxypropyl te tere o te pupuri wai o te hydroxypropyl methylcellulose. Ko te painga o te waikura, te ōwehenga o te methyl chloride me te propylene oxide, te kukū o te kawakore me te ōwehenga o te wai ki te miro para hei whakatau i te mahi o te hua.
Ko te kounga o nga rauemi mata, ko te paanga o te whakamaaramatanga, ko te mana owehenga o te tukanga, ko te tauwehenga o nga whakarewa me te paanga o te whakakorenga ka whakatau katoa i te kounga o te hydroxypropyl methylcellulose, ka mahia etahi hydroxypropyl methylcellulose ki te memeha I muri iho, he kapua ka rite ki te taapiri miraka, he miraka ma etahi, he kowhai etahi, he maamaa, he marama etahi. 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 ahetiki ki te whakawhiti marama. He pai ake te whakamahi i te waikawa acetic i muri i te waimehatanga. Ko te awe nui ko te whakakorikoritanga o te tauhohenga me te pumau o te owehenga o te punaha (he makuku etahi o nga rawa, he koretake te ihirangi, penei i nga whakarewa tukurua). Ko te mea pono, He maha nga ahuatanga kei te takaro. Ma te pumau o nga taputapu me nga mahi a nga kaiwhakahaere kua whakangungua, me tino pumau nga hua ka puta. Ko te whakawhiti marama e kore e neke ake i te awhe o ± 2%, me te pai te whakahaere i te riterite whakakapinga o nga roopu whakakapi. Engari i te riterite, ka tino pai te whakawhiti marama.
