I roto i te moata whakamaarama o te whare me te paura putty, ko te rahi o te hydroxypropyl methylcellulose purea 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?Hei awhina i a koe ki te whakautu i tenei patai i tenei ra.
I roto i te tukanga whakaputa o te hydroxypropyl methylcellulose, ko te hāora e toe ana i roto i te kettle tauhohenga ka arahi ki te paheketanga o te hydroxypropyl methylcellulose me te whakaiti i te taumaha ngota.Heoi, he iti te toenga o te hāora, no reira karekau he uaua ki te whakapiri ano i nga ngota ngota kua pakaru.Ko te reiti waiwai matua me te ihirangi hydroxypropyl he hononga nui, ko etahi wheketere e hiahia ana ki te whakaiti i te utu me te utu, kaore e hiahia ki te whakapai 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 i te wai o te hydroxypropyl methylcellulose me te hydroxypropyl he hononga nui hoki, a mo te tukanga urupare katoa, ka whakatauhia e te hydroxypropyl methylcellulose te tere o te pupuri wai o te hydroxypropyl methylcellulose.Ko te painga o te waikura, te ōwehenga o te chloromethane ki 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, te paanga o te waikura, te whakahaere i te tauwehenga o te tukanga, te tauwehenga whakarewa me te painga o te whakakore, ka whakatau katoa i te kounga o te hydroxypropyl methyl cellulose, etahi hydroxypropyl methyl cellulose i hangaia ki te memeha i muri i te ahua o te miraka he tino kapua, etahi miraka ma, etahi kowhai, etahi 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, ka pai te whakamahi i te waikawa acetic i muri i te waimehatanga, ko te paanga nui, ko te whakakorikori hohenga ranei he rite, he pumau te ōwehenga o te punaha (ko etahi makuku rauemi, kaore i te pumau te ihirangi, penei i te whakaoranga o te whakarewa), i roto i te meka, he maha nga mea e pa ana.Ma te pumau o nga taputapu me nga mahi a nga kaiwhakangungu whakangungu, me tino pumau nga hua ka puta.Kaua e neke ake i te ±2% te whakawhiti, me te pai te whakahaere i te riterite whakakapinga o te roopu whakakapi.Whakakapi rite, me pai te whakawhiti.
Na reira, ko te kounga pai o te hua ka whakatauhia e nga rauemi mata, hangarau whakaputa, me etahi atu mea.Ko te mana kaha anake mai i tetahi pito ki te mutunga ka taea te whakaputa hua me te kounga pumau.
