Iyo yakaderedzwa kureba kweye test block mu mold mushure mekuumbwa inoratidza mhedzisiro yehydroxypropyl methylcellulose pane kugadzikana kwevhoriyamu yekongiri ine furo. Zvinogona kuonekwa kuti dosage ye0.05% hydroxypropyl methylcellulose ndiyo yakanakira dosage, uye kana dosi yehydroxypropylmethylcellulose iri 0.05%, kureba kwekudzikisa kunowedzera zvishoma nezvishoma. Kuongorora kunoratidza kuti kana iyo hydroxypropyl methylcellulose yakakodzera, inogona kuderedza vhoriyamu shrinkage yemuviri wakaomeswa uchivandudza fluidity ye slurry. Munguva yekuomeswa kwe slurry, mvura inoramba ichirasika. Iyo furo yemukati zvakare inogara ichiodzwa mwoyo, uye kupfupika kwemuviri wakaoma hakudzivisiki. Izvi zvinoita kuti huwandu hwemuviri wakaoma huve husina kugadzikana, uye kusanganiswa kwehydroxypropyl methylcellulose haisi kungopa muviri wakaoma Haisi kungoita zvakanaka kuchengetedza mvura, asiwo inogadzirisa uye inoomesa furo rekutanga kuburikidza nemaitiro e slurry kuoma uye hydroxypropyl. methylcellulose firimu kuomesa panguva imwe chete, kuitira kuti itambe yakanaka furo inodzikamisa mhedzisiro uye kuderedza shrinkage yekuomeswa kwehuwandu hwemuviri.
Webetsero furo kugadzikana
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 mekunge hydroxypropyl methylcellulose yanyungudutswa, bhaisikopo rakanyorova rakanyorova rinoumbwa pakati peakasimba chikamu zvidimbu uye gasi chikamu mabhubhu, ane yakanakisa yakatsetseka mhedzisiro 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.
