Ko te methylcelcrosel, e mohiotia ana hoki ko te hypromelellose me te cellulose hydroxypropyl methyl eter
Te rereke:
Nga ahuatanga rereke
Ko te methylcellolose: te hinu ma te muka-ma ranei, he momo kore-Ionic ranei, ko tenei hua he kaikohuru hakihaki.
Ko te CellDroxyethyl he ma, he kowhai ranei, he kakara kore-paitini, ko te papanga totika te konutai ko te cellulose kore-koiora.
He rereke te whakamahi
I roto i te ahumahi peita, te hydroxypropyl methylcellulose he pai te whakaheke i te wai, i te whakarewa o te organic ranei hei thickener, marara me te whakatuu. Ko te polyvinyl chloride e whakamahia ana hei peita peita mo te polymerization aukati hei whakarite i te hiako polyvinyl, e whakamahia nuitia ana i roto i te hiako, nga hua pepa, nga kakano me etahi atu ahumahi.
Te hydroxypropyl methylcellulose: tata ki te kore e taea te whakakorekore, eter, acetone; Ko te otinga o te otinga maamaa, te kowhatu ranei i roto i te wai makariri, i roto i nga koti, i roto i nga hiu, nga miiharo, nga pepeke hua, te rongoa o te hinu me nga hinu rongoā.
rereke te rereketanga
Te hydroxypropyl methylcellulose: tata ki te kore e taea te whakakorekore, eter, acetone; Ko te otinga o te otinga maamaa marama, paku ranei i te wai makariri.
Hydroxyethyl cellulose (hec): Ka taea e ia te whakarite i nga otinga i roto i nga momo ahua rereke, a he pai te horoi tote-horoi mo nga hikohiko.
