HPMC icotton cellulose yakachena kwazvo seyakagadzirwa, pasi pemamiriro e-alkaline kuburikidza 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, kusaramba kwemunyu, kuderera kwedota poda, pH kugadzikana, kuchengetedza mvura, kugadzikana kwedimensional, yakanakisa kuumbwa kwefirimu, uye kuwanda kwe enzyme kuramba, kupararira uye kunamatira.
HPMC, Hydroxypropyl Methylcellulose marudzi e-non-ionic cellulose ether, ayo ari poda kubva kuchena kusvika kune chena ruvara, inoshanda seyakakora, 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 zvinowedzera zvine yakaderera, zvichiita kuti HPMC ive inoshamisa inoshanda uye inoshanda yekuwedzera munzvimbo yekunamatira, kuvaka, chikafu, zvigadzirwa zvemumba, mishonga uye nezvimwe.
