Mumatope akagadzirira-akasanganiswa, kuwedzerwa kwe cellulose ether kwakaderera zvikuru, asi kunogona kuvandudza zvakanyanya kushanda kwedhaka rakanyorova, iro rinowedzera kuwedzera kunokanganisa kushanda kwekuvaka kwedhaka.basa rakakosha reHPMC mudhaka rinonyanya kuita zvinhu zvitatu, imwe ndiyo yakanakisa yekuchengeta mvura, yechipiri mhedzisiro yekusagadzikana kwedhaka, uye chechitatu ndiko kusangana nesamende.
1. Iyo yakakura viscosity ye cellulose ether, zviri nani kuchengetedza mvura kuita.
2. Iyo yakakura kuwedzera huwandu hweselulosi ether mudhaka, zviri nani kuchengetedza mvura kuita.
3. Pakukura kwechidimbu, iyo yakatsetseka chidimbu, zviri nani kuchengetedza mvura.
4. Kuchengetwa kwemvura kwemethyl cellulose ether kunoderera nekuwedzera kwekushisa.
Iko kukora mhedzisiro yehydroxypropyl methyl cellulose seyakakora inoenderana nekukura kwechikamu, viscosity uye kugadziridzwa kwehydroxypropyl methyl cellulose.Kazhinji kutaura, kukwirisa viscosity ye cellulose ether, iyo diki saizi yechikamu, kunowedzera kuoneka kwehupfu.
Basa rechitatu re cellulose ether ndere kudzoreredza hydration process ye simenti.Cellulose ethers inopa dhaka zvakasiyana-siyana zvinobatsira zvivakwa uye zvakare kuderedza yekutanga hydration kupisa kuburitsa simende uye kudzoreredza hydration simba rekuita simende.Kukwirisa kusanganiswa kwe cellulose ether mumineral gel zvinhu, ndiko kunowedzera kujeka mhedzisiro yekunonoka hydration.Cellulose ethers haingodzoredzi kugadzika, asi zvakare inonoke kuomarara kwesamende dhaka masisitimu.Nekuwedzera kweHPMC dosing, nguva yekumisikidza yedhaka yakawedzera zvakanyanya.
Muchidimbu, mune yakagadzirira-yakasanganiswa dhaka, HPMC inoita basa rekuchengetedza mvura, kukora, kunonoka hydration simba resimende uye kuvandudza mashandiro ekuvaka.Iyo yakanaka yekuchengeta mvura kugona kunoita kuti simende hydration iwedzere kuzara, izvo zvinogona kuvandudza kunyorova kunamatira kwedhaka rakanyorova uye kuwedzera kusimba kwechisungo chedhaka.Naizvozvo, HPMC iri kushandiswa zvakanyanya sechinhu chakakosha chekuwedzera mune yakagadzirira-yakasanganiswa dhaka.
