Ko te Hydroxypropyl methylcellulose, e mōhiotia ana ko te hypromellose me te cellulose hydroxypropyl methyl ether, he mea hanga mai i te cellulose miro tino parakore, ā, ka whakaeterihia i raro i ngā āhuatanga kawakore.
te rerekētanga:
ngā āhuatanga rerekē
Hydroxypropyl methylcellulose: paura, kirikiri rānei, he rite ki te muka mā, nō ngā momo kore-ionic i roto i te ranunga cellulose, he pūhui viscoelastic kore-mahi, haurua-hanga tēnei hua.
Ko te Hydroxyethyl cellulose he muka mā, he kowhai rānei, he kakara kore, he paura totoka rānei, ko te rauemi mata matua he cellulose alkali me te ethylene oxide etherification, he cellulose ether wairewa kore-ionic.
He rerekē te whakamahinga
I roto i te umanga peita, he pai te wairewatanga o te hydroxypropyl methylcellulose ki te wai, ki ngā whakarewa rauropi rānei hei whakamātotoru, hei whakamarara, hei whakaū hoki. Ka whakamahia te polyvinyl chloride hei tango peita mō te whakapūhuitanga whakatārewatanga hei whakarite i te polyvinyl chloride, e whakamahia whānuitia ana i roto i te hiako, ngā hua pepa, te tiaki hua me te huawhenua, ngā kakahu me ētahi atu ahumahi.
Hydroxypropyl methylcellulose: tata kore e wairewa i roto i te etanoru tino, te etera, te acetone; wairewa i roto i te wairewa koloidal mārama, pōuri rānei i roto i te wai matao, e whakamahia whānuitia ana i roto i ngā paninga, waituhi, muka, tae, hanga pepa, whakapaipai, patupatu, kohuke. Tukatuka hua, whakaora hinu me ngā ahumahi rongoā.
rerekē te wairewatanga
Hydroxypropyl methylcellulose: tata kore e wairewa i roto i te etanoru tino, te etera, te acetone; ka wairewa i roto i te wai koloidal mārama, paku kapua rānei i roto i te wai matao.
Hydroxyethyl cellulose (HEC): Ka taea e ia te whakarite i ngā otinga i roto i ngā awhe matotoru rerekē, ā, he pai hoki ōna āhuatanga whakarewa tote mō ngā electrolytes.
