HPMC icotton cellulose yakanyanya kuchena seyakagadzirwa, pasi pemamiriro e-alkaline ne-etherification yakakosha uye kugadzirira.Ichena kana chena poda.HPMC inoderera nekuderera kwemethoxide content, kuwedzera kwegel point, kuderera kwekunyungudika kwemvura uye kuderera kwebasa repamusoro.
HPMC ine kugona kukora, kurwisa munyu, yakaderera dota hupfu, pH kugadzikana, kuchengetedza mvura, kugadzikana kwedimensional, yakanakisa kuumbwa kwemafirimu, uye kuwanda kwe enzyme kuramba, kupararira uye kunamatira.
HPMC, Hydroxypropyl Methylcellulose marudzi e-non-ionic cellulose ether, ayo ari poda yechena kusvika kunze kwemavara machena, anoshanda semukobvu, binder, firimu-yaimbova, surfactant, inodzivirira colloid, lubricant, emulsifier uye kuturika uye rubatsiro rwekuchengetedza mvura. Pamusoro pezvo, kune marudzi ema cellulose ethers anoratidza zvimiro zve thermal gelation, metabolic inertness, enzyme resistance, kunhuwa kwakaderera uye kuravira, uye PH kugadzikana.
Nekuda kwemakumi ezviuru ezvivakwa, HPMC inowanzo shandiswa kutsiva zvimwe zvakawanda zvekuwedzera nekushomeka kwakadzika, zvichiita kuti HPMC ive inoshamisa inoshanda uye inoshanda yekuwedzera munzvimbo yekunamatira, kuvaka, chikafu, zvigadzirwa zvemumba, mishonga uye nezvimwe.
