Ko te Hydroxypropyl methylcellulose he ether cellulose kore-ionic i hangaia mai i te cellulose rauemi polymer taiao ma te raupapa o nga tukanga matū. He momo paura ma karekau, karekau, karekau he paitini, ka pupuhi i roto i te wai matao, ka kiia ko te wairewa colloidal maamaa, paku kapua ranei. Kei a ia nga ahuatanga o te whakapakeke, te here, te whakamarara, te whakaemulsifying, te hanga kiriata, te whakatārewa, te adsorbing, te gelling, te kaha o te mata, te pupuri i te makuku me te tiaki i te colloid.
Ka taea e te hydroxypropyl methylcellulose pai te whakaoti i te raru o te pupuri wai i raro i te wera nui. I nga wa wera nui, ina koa i nga waahi wera me nga waahi maroke me te hanga angiangi-papa ki te taha paki, ka hiahiatia te HPMC hydroxypropyl methylcellulose kounga teitei hei whakapai ake i te pupuri wai o te slurry.
Ko te hydroxypropyl methylcellulose kounga teitei he tino pai te riterite. Ko ona roopu methoxy me te hydroxypropoxy kua tohatohahia ki te taha o te mekameka ngota cellulose, ka taea te whakarei ake i nga ngota hāora i runga i nga here hydroxyl me te ether me te hononga wai. Ko te kaha ki te whakakotahi me te hanga i nga here hauwai ka huri te wai kore utu ki te wai herea, na reira ka pai te whakahaere i te whakaetonga o te wai na te nui o te wera o te rangi me te pupuri i te wai teitei.
