Hydroxyethyl cellulose
He polymer kore-katote wai-wairewa, he ma, he paku kowhai ranei, he ngawari te rere o te paura, he hongi me te kore reka, he wairewa i roto i te wai matao me te wai wera, a ka piki ake te reiti rewa i te pikinga o te pāmahana.Karekau i roto i nga whakarewa pararopi.
Nga ahuatanga o te hydroxyethyl cellulose:
1. He wairewa te HEO i roto i te wai wera, i te wai matao ranei, karekau e heke i te wera nui, te koropuputanga ranei, na reira he maha nga ahuatanga o te whakarewatanga me te pokey, tae atu ki te waiariki kore.
2. Ka taea e te katote-kore ake te noho tahi me te tini o etahi atu polymers wairewa-wairewa, surfactants me te tai, a he pai rawa atu te whakamaarata colloidal mo nga otinga electrolyte teitei.
3. Ko te kaha o te pupuri i te wai e rua ake te teitei o te methyl cellulose, a he pai ake te whakahaere o te rere.
4. Ka whakatauritea ki te methyl cellulose me te hydroxypropyl methyl cellulose, ko te kaha marara o HEC te mea kino rawa atu, engari ko te kaha o te colloid tiaki te kaha.
