Hydroxypropyl methylcellulose HPMC irashobora kunoza cyane gufata amazi ya minisiteri.Iyo amafaranga yiyongereye ari 0,02%, igipimo cyo gufata amazi kiziyongera kuva kuri 83% kigere kuri 88%;amafaranga yiyongereye ni 0.2%, igipimo cyo gufata amazi ni 97%.Muri icyo gihe, umubare muto wa HPMC nawo ugabanya cyane igipimo cyo gutondeka no kuva amaraso ya minisiteri, ibyo bikaba byerekana ko HPMC idashobora gusa kunoza imikoreshereze y’amazi ya minisiteri, ahubwo inatezimbere cyane ubufatanye bwa minisiteri, kandi cyane bifite akamaro kuburinganire bwubwubatsi bwa minisiteri.
Nyamara, hydroxypropyl methylcellulose HPMC igira ingaruka mbi kumbaraga zoroshye nimbaraga zo kwikuramo za minisiteri.Hamwe no kwiyongera kwinyongera ya HPMC, imbaraga zihindagurika nimbaraga zo kwikuramo za minisiteri zigabanuka buhoro buhoro.Mugihe kimwe, HPMC irashobora kongera imbaraga za minisiteri.Iyo ingano ya HPMC iri munsi ya 0.1%, imbaraga zingana za minisiteri ziyongera hamwe no kwiyongera kwa dosiye ya HPMC.Iyo amafaranga arenze 0.1%, imbaraga za tensile ntiziyongera cyane.Hydroxypropyl Methyl
Cellulose HPMC nayo yongerera imbaraga za minisiteri.0.2% HPMC yongereye imbaraga zububiko bwa minisiteri kuva kuri 0,72 MPa igera kuri 1.16 MPa.
Ubushakashatsi bwerekanye ko HPMC ishobora kongera igihe cyo gufungura minisiteri, kuburyo umubare wa minisiteri ugabanuka wagabanutse cyane, bikaba byiza cyane mukubaka amabati.Iyo HPMC itavanze, imbaraga zububiko bwa minisiteri zagabanutse ziva kuri 0,72 MPa zigera kuri 0.54 MPa nyuma yiminota 20, naho imbaraga za minisiteri hamwe na 0.05% na 0.1% HPMC zizaba zitandukanye 0.8 MPa na 0.84 MPa nyuma ya 20min.Iyo HPMC itavanze, kunyerera ya minisiteri ni 5.5mm.Hamwe no kwiyongera kwa HPMC, kunyerera bizakomeza kugabanuka.Iyo dosiye ari 0.2%, kunyerera kwa minisiteri bigabanuka kugera kuri 2,1mm.
