Sezvo huwandu hwehydroxypropyl methylcellulose hwakawedzera kusvika 0.5%, kudonha kwakadzikira zvishoma.Iyo data inoratidza kuti kana iyo hydroxypropyl methylcellulose yemukati isingapfuure 0.05%, kuwedzerwa kwehydroxypropyl methylcellulose kunogona kuvandudza zvakanyanya fluidity uye viscosity yefoamed kongiri slurry.Mushure mokunge hydroxypropyl methylcellulose yanyungudutswa, firimu rakanyorova rinonyorova rinoumbwa pakati pezvikamu zvakasimba zvechikamu uye gasi chikamu chebubbles, iyo ine unhu hwakanaka hwekuita panguva yekusanganiswa.Slurry yakasununguka uye yunifomu "bhora", iyo inobudirira inovandudza fluidity yezvitsva zvakasanganiswa slurry: asi kana chiyero che hydroxypropyl methylcellulose chinopfuura 0.5%, slurry ichava yakanyanyisa uye mvura inoyerera ichaderedzwa zvikuru.Zvisinei, 0.05% hydroxypropyl methylcellulose haingoiti chete kudonha, asiwo inodzikamisa mabhuru emhepo, ayo akakodzera kuwedzera vanhu.
