Ko te ma o te hydroxypropyl methylcellulose i roto i te hanga moata whakamatao me te paura putty e pa ana 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 whakaheke 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 reiti pupuri wai o te hydroxypropyl methylcellulose he hononga nui ano 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 paanga 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 rawa mata, ko te paanga o te waikura, 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 mai, he kapua ano he taapiri. he 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 taurite o te owehenga o te punaha (he makuku etahi o nga rawa, karekau te ihirangi, penei i nga whakarewa tukurua).Ko te mea pono, He maha nga mea 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 atu i te awhe o ± 2%, me pai te whakahaere i te riterite whakakapinga o nga roopu whakakapi.Engari i te riterite, ka tino pai te whakawhiti marama.
