Imwe chiyero che hydroxypropyl methylcellulose ether inochengeta mvura mudhaka kwenguva yakakwana kuti ikurudzire kuenderera kwe hydration ye simenti uye kuvandudza kunamatira pakati pedhaka ne substrate.
Mhedzisiro Yechikamu Chekukura uye Kusanganiswa Nguva yeHydroxypropyl Methyl Cellulose Ether paKuchengeta Mvura
Iyo yekuchengetera mvura yedhaka inodzorwa zvakanyanya nenguva yekunyungudika, uye iyo yakatsetseka cellulose inonyungudika nekukurumidza, uye nekukurumidza kuchengetedza kwemvura ndiko. Nokuda kwekugadzirwa kwemichina, nekuda kwezvipingamupinyi zvenguva, sarudzo ye cellulose inofanira kuva poda yakatsetseka. Nekupurasita nemaoko, hupfu hwakatsetseka huchaita.
Mhedzisiro yeEtherification Degree uye Tembiricha yeHydroxypropyl Methyl Cellulose Ether paKuchengeta Mvura
Kunyungudika uye tembiricha yehydroxypropyl methylcellulose mumvura zvinoenderana nedhigirii reetherification. Sezvo kunze kwekushisa kunokwira, kuchengetwa kwemvura kunoderera; iyo yakakwirira yedhigirii etherification, zviri nani kuchengetwa kwemvura ye cellulose ether.
Mhedzisiro yehydroxypropyl methylcellulose ether pakuenderana uye kutsvedza kuramba kwedhaka.
Kusagadzikana uye anti-kutsvedza midziyo yedhaka zviratidzo zvakakosha, zvese zvekuvaka gobvu dhizaini uye yekunamira mataira inoda kuenderana kwakakodzera uye anti-kutsvedza pfuma.
Consistency test nzira, yakatemwa zvinoenderana neJG/J70-2009 chiyero
Consistency uye kutsvedza kuramba kunonyanya kuzivikanwa neiyo viscosity uye particle size yehydroxypropyl methylcellulose. Nekuwedzera kwe viscosity uye zvinyorwa, kuwirirana kwedhaka kunowedzera; kukwenenzvera ukuru hwechidimbu, kunowedzera kuenderana kwekutanga kwedhaka richangobva kusanganiswa. quick.
Mhedzisiro yeHydroxypropyl Methyl Cellulose paMhepo Entrainment yeMortar
Nekuda kwekuwedzera kwehydroxypropyl methylcellulose mudhaka, imwe huwandu hwediki, yunifomu uye yakagadzikana mabhuru emhepo anounzwa mudhaka richangobva kusanganiswa. Nekuda kwekuita kwebhora, iyo dhaka ine yakanaka yekuvaka uye inoderedza shrinkage uye torsion yedhaka. Kutsemuka, uye kuwedzera chiyero chekubuda kwedhaka. Cellulose ine mhepo-inopinza basa. Paunenge uchiwedzera cellulose, funga nezve dosage, viscosity (yakanyanyisa viscosity inokanganisa kushanda), uye mhepo-inopinza zvinhu. Sarudza cellulose kune dzakasiyana dhaka.
