Mune yakaoma yakasanganiswa yakagadzirira yakasanganiswa dhaka, zvirimo zveHPMCE zvakaderera zvakanyanya, asi zvinogona kuvandudza mashandiro edhaka rakanyorova. Kusarudzwa kunonzwisisika kweselulosi ether nemhando dzakasiyana, viscosity yakasiyana, saizi yakasiyana-siyana, dhigirii re viscosity uye huwandu hwekuwedzera kune pesvedzero pakuita kwedhaka rakaoma. Parizvino, akawanda masonry uye plastering dhaka rekuchengetedza mvura kuita hakuna kunaka, maminetsi mashoma achaonekwa zvishoma static mvura slurry kupatsanurwa. Kuchengetedzwa kwemvura chinhu chakakosha cheMethyl cellulose ether, iyo inobatawo nevazhinji vanogadzira dhaka rakaoma muChina, kunyanya kumaodzanyemba uko tembiricha yakakwira. Zvinhu zvinokanganisa kuchengetwa kwemvura yedhaka rakaoma zvinosanganisira huwandu hweselulosi ether HPMC, viscosity ye cellulose ether HPMC, kunaka kwezvimedu uye tembiricha yezvakatipoteredza. Cellulose ether imhando yekugadzira polymer yakagadzirwa kubva kune yakasikwa cellulose nekugadziriswa kwemakemikari. Mvura-soluble cellulose ether inoita basa rakakosha mudhaka muzvikamu zvitatu, imwe ndiyo yakanakisa yekubata mvura, imwe ndeye pesvedzero pane dhaka kusawirirana uye thixotropy, uye yechitatu ndiko kudyidzana nesamende. Basa rekuchengetedza mvura re cellulose ether rinoenderana nekutorwa kwemvura pachigadziko, kuumbwa kwedhaka, kukora kwedhaka, kudiwa kwemvura kwedhaka uye nguva yekumisikidzwa kwezvinhu zvekugadzika. Kuchengetwa kwemvura kwe cellulose ether pachayo kunobva mukunyungudika uye kupera simba kweselulosi ether pachayo.
Kupfupisa, mune yakaoma-yakasanganiswa yakagadzirira-yakasanganiswa dhaka, hypromellose inotamba basa rekuchengetedza mvura, kukora, kudzoreredza hydration simba resimende, kuvandudza kushanda kwekuvaka, nezvimwewo. Yakanaka-inobata mvura inoita kuti simende hydration iwedzere kuzara, inogona kuvandudza yakanyorova viscosity yedhaka rakanyorova, kuvandudza kusimba kwechisungo chedhaka, inogona kugadzirisa nguva. Kuwedzerwa kwe hypromellose kunogona kuvandudza mashandiro ekuvaka uye kusimba kwesimba redhaka. Naizvozvo, cellulose ether iri kushandiswa zvakanyanya sechinhu chakakosha chekuwedzera mune yakaoma-yakasanganiswa yakagadzirira-yakasanganiswa dhaka.
