Hydroxypropyl Methylcellulose
HydroxypropylMethylcellulose (HPMC) hypromellose raneihe pärönakis o Methyl cellulose etere. Ko tehe ma, he ma, he kikorangi, he kirikiri raneiether cellulosepaura. I tenei wa ko te cellulose etere me te mahi pai rawa atu i te ao, te whakakotahi i te whakamatotoru, te whakatarewa, te whakamarara, te whakaehunga me te whakapumau. Hydroxypropyl methyl cellulose (HPMC) he kore paitini, he ngawari ki te whakamahi, he ngawari te wairewa ki te wai. He polyanion i roto i te wairewa wai, a, he ahurei to tinana. Ko te mahi motuhake penei i raro nei:

Āhuatanga:
1. Wairewa: He tata kore e rewa i roto i te ewaro tino, te etera me te acetone, ka memeha ki te wairewa colloidal marama, paku puhoi ranei i roto i te wai matao. Ka taea te rewa i roto i etahi whakarewa pararopi, ka taea hoki te rewa i roto i te whakarewa whakauru o nga whakarewa wai-organic.
2. Te tote tote: He ahua pumau i roto i nga wairewa wai i te wa e noho ana nga tote whakarewa, nga electrolytes waro ranei.
3. Te mahi mata: ka taea te whakamahi hei whakamarumaru colloid, emulsifier me te dispersant.
4. PH-pumautanga: Ko te uara PH he tino pumau i roto i te awhe o 3.0 ~ 11.0. Ko te pokey o te wairewa wai karekau e pa ki te waikawa me te kawakore.
