Soluble hydroxypropyl methyl selulose (HPMC) ni ubwoko bwa ether ionic selulose ether, ikozwe muri selile naturel ya selile isanzwe ikoresheje uburyo bwo gutunganya imiti. Hypromellose (HPMC) ni ifu yera ishonga mumazi akonje kugirango ibe igisubizo kiboneye, kibonerana. Ifite imiterere yo kubyimba, gufatira, gutatanya, emulisile, gukora firime, guhagarika, adsorption, gelation, ibikorwa byubutaka, kubika amazi no kurinda colloid. Kubika amazi ni umutungo wingenzi wa hypromellose HPMC, nayo ihangayikishijwe n’inganda nyinshi zivanze na minisiteri mu Bushinwa. Ibintu bigira ingaruka ku kugumana amazi ya minisiteri ivanze n’amazi harimo ingano ya HPMC, ubwiza bwa HPMC, ingano y’ibice hamwe nubushyuhe bwibidukikije. Hypromellose HPMC igira uruhare runini muri minisiteri mu bintu bitatu: gufata neza amazi, ingaruka zayo kuri minisiteri ya minisiteri na thixotropy, n'imikoranire yayo na sima. Igikorwa cyo kugumana amazi ya selulose ether biterwa no kwinjiza amazi yibanze, ibigize minisiteri, ubunini bwa minisiteri, amazi akenerwa na minisiteri nigihe cyo kugenera ibikoresho. Kurenza hypromellose, niko gufata amazi neza.
Mu bintu bigira ingaruka ku kugumana amazi ya minisiteri harimo ubwiza bwa selulose ether, umubare wongeyeho, ubwiza bwibice hamwe nubushyuhe bwa serivisi. Ninshi ubwiza bwa selulose ether, niko gufata amazi neza. Viscosity nikintu cyingenzi cyimikorere ya HPMC. Kubicuruzwa bimwe, bipimwe nuburyo butandukanye bwibisubizo byibisubizo biratandukanye cyane, ndetse bamwe bakubye kabiri itandukaniro. Kubwibyo, mugihe ugereranije viscosity, bigomba kuba muburyo bumwe bwo kugerageza hagati, harimo ubushyuhe, rotor nibindi. Muri rusange, uko ubukonje buri hejuru, ningaruka nziza yo gufata amazi. Nyamara, uko ubukonje buri hejuru, niko uburemere bwa molekuline ya HPMC ari ninshi, imbaraga za HPMC zizagabanuka uko bikwiye, bigira ingaruka mbi ku mbaraga n’imikorere ya minisiteri. Iyo hejuru yubukonje, ningaruka zo kubyimba za minisiteri, ariko ntabwo bihuye nubusabane. Iyo hejuru yubusembwa, niko amabuye atose azaba menshi, haba mubwubatsi, imikorere yo gufatisha scraper hamwe no gufatira hejuru kuri substrate. Ariko ntabwo ari byiza kongera imbaraga zimiterere ya minisiteri yonyine. Byombi kubaka, imikorere yo kurwanya-kugabanuka. Ibinyuranye, hypromellose yahinduwe hamwe nubucucike buke kandi buciriritse bwerekanye imikorere myiza mugutezimbere imbaraga zimiterere ya minisiteri itose. Iyo ibintu byinshi biri muri selulose ether muri minisiteri, nibyiza umutungo ufata amazi, niko ubukonje bwiyongera hamwe nibintu byiza bifata amazi. Ubwiza nabwo ni ikimenyetso cyingenzi cyerekana hypromellose. Ubwiza bwa hypromellose nabwo bugira ingaruka runaka kubushobozi bwayo bwo gufata amazi. Muri rusange, kuri hypromellose ifite ububobere bumwe ariko ubwiza butandukanye, munsi yumubare wongeyeho, nibyiza, nibyiza byo gufata amazi.
Muri minisiteri ivanze neza, hiyongereyeho selile ether HPMC iri hasi cyane, ariko irashobora kunoza imikorere yubwubatsi bwa minisiteri ivanze. Guhitamo neza hypromellose bifite ingaruka zikomeye kumikorere ya minisiteri ivanze.
