Te Kaihanga Hainamana Tino Maamaa Te Whakapai Ringa Paura Whakatotoa Hydroxypropyl Methyl Cellulose HPMC
HPMChe katote-kore, he wairewa cellulose ether e hanga kiriata, pupuri wai, pumau, piri, inaa ka whakamahia mo nga rawa hanga na te mea kua whiriwhiria hei whakarei ake i te piri, te pupuri wai, me te whakahinuhinu, te whakaheke me te kapiti te aukati.Ko nga etero cellulose kua whakarereketia ka pai ake i runga i te pahekeheke, te parenga pakaru ki te pehanga me te ira tangata.Na reira, mo nga motika raima me te raima, ko to whiringa pai rawa atu.He paura ma, he ma-ma ranei, he kore-paitini kaore he reka, he ngawari ki te wairewa i te wai wera, matao ranei.
HPMCwhakamahia hoki mo uku, tupeka me horoi, etc.
Mo nga tikanga rereke o te here,YoungcelKa taea e ia te whakarato i nga momo hua ether cellulose ki te whakatutuki i nga whakaritenga rereke.
