Ngalegles: C2H6O2 Xch4o X Pheur 2002 e tautuhi ana i te hydroxyethylmethylcelcelfetlcelose hei waahanga o-methylated, he waahanga o-hydroxymerylated. Ko nga whakaritenga rereke e whakaatuhia ana i runga i nga ahuatanga o te tirohanga kitea i roto i te MPA S o te otinga 2% w / v i te 20 ° C.
Taumaha Momotu: Ko te Pheur 2002 e tautuhi ana i te hydroxyethylmethylcelfetlcelose ko tetahi o-methylated, he waahanga o-hydroxymerylated cellulose. Ko nga whakaritenga rereke e whakaatuhia ana i runga i nga ahuatanga o te tirohanga kitea i roto i te MPA S o te otinga 2% w / v i te 20 ° C.
Ko nga ahuatanga matua o te hydroxyethyl methyl cellulose (Hemc):
1
2
3. Nga Mahi Mata: I te mea ko te otinga o te mahi he mahi ngohe, ka taea te whakamahi hei kaihoko tiaki Colloid, emulsifier me te marara.
4 . Ko te pāmahana e whakawhirinaki ana ki o raatau hinu whakaranu, te aukati i nga awhina awhina, nga kohinga paruru, emulsifiers, me etahi atu.
5
6. Antifengal: He pai te kaha a Hemc me te pumau i te waa i roto i te rokiroki mo te wa roa.
7HemcKo te otinga waiariki e tino pa ana ki te waikawa, i te alkali ranei, a ko te uara pH he pumau tonu i te whānuitanga o te 3.0-11.0.
Tono: Ka taea te whakamahi i te hydroxyethyl methyl cellulise hei kaihoko tiaki Colloid, emulsifier me te marara na te taumata kaha o te otinga o te otinga. Ko te tauira o tana tono e whai ake nei: te hua o te hydroxyethyl cellulose i runga i nga waahanga o te raima. Ko te Mydroxyethyl methylcellulose he kakara, he koretake, he koretake ma e rewa ana i te wai makariri hei hanga i te otinga maamaa. Kei a ia nga paanga o te matotoru, te herea, te marara, te whakakii, te aukati, te taapiri, te makuku, te pupuri i te makuku me te tiaki i te makuku. Na te mea ka kaha te mahi a te papa o te otinga wai, ka taea te whakamahi hei kaihoko tiaki Colloid, he emulsifier me te marara. Ko te otinga o te kohinga cellulose methyl he pai te hydrophilility me te kaihoko-pumau tonu-e mau tonu ana i te mana-pumau.
