Ko te Hydroxypropyl methylcellulose, e mohiotia ana ko te hypromellose me te cellulose hydroxypropyl methyl ether, he mea hanga mai i te miro cellulose tino parakore, he mea whakahiato i raro i nga tikanga kawakore.
te rereke:
āhuatanga rerekē
Hydroxypropyl methylcellulose: he ma, he ma, he muka-rite te paura, he kirikiri ranei, no nga momo momo kore-katote i roto i te ranunga cellulose, ko tenei hua he mea hangarua, he polymer viscoelastic hohekore.
Ko te Hydroxyethyl cellulose he ma, he kowhai ranei, he kakara, he muka kore-paitini, he paura totoka ranei, ko te mea matua ko te cellulose alkali me te ethylene oxide etherification, he ether cellulose wairewa-kore.
He rereke te whakamahi
I roto i te ahumahi peita, he pai te whakarewatanga o te hydroxypropyl methylcellulose i roto i te wai, i nga whakarewa pararopi ranei hei whakapakeke, whakamararatanga me te whakapumau.Ka whakamahia te polyvinyl chloride hei tango peita mo te polymerization whakatārewatanga ki te whakarite i te polyvinyl chloride, e whakamahia nuitia ana i roto i te hiako, hua pepa, hua me te tiaki huawhenua, kakano me etahi atu ahumahi.
Hydroxypropyl methylcellulose: tata kore e rewa i roto i te ewaro tino, ether, acetone;he wairewa i roto i te wairewa colloidal maramara, turbid ranei i roto i te wai matao, e whakamahia nuitia ana i roto i te paninga, te waituhi, te muka, te tae, te hanga pepa, te whakapaipai, te pesticides, te kohuke Tukatuka hua, whakaora hinu me nga ahumahi rongoa.
rereke rereke
Hydroxypropyl methylcellulose: tata kore e rewa i roto i te ewaro tino, ether, acetone;wairewa i roto i te wairewa colloidal marama, paku kapua ranei i roto i te wai matao.
Hydroxyethyl cellulose (HEC): Ka taea e ia te whakarite rongoā i roto i nga awhe pokey rereke, me te pai o te tote-whakarewa mo nga electrolytes.
