Kuiswa kweEipponCell® HEMC LH 620M Cellulose ether mudhaka kunoguma nekushanda kuviri kwekuchengetedza mvura nekukora.Kunyangwe pachiyero chidiki che 0.2%, inodzikisira zvakanyanya nyaya dzekudonha mukupurasita dhaka rakagadzirirwa kongiri yakadzidziswa nemhepo, panguva imwe chete ichiwedzera kugona kwekuchengetedza mvura kwedhaka, zvichiratidza kushanda kunoshamisa muchikamu ichi.
Uyezve, HEMC inoratidzira inherent air-entraining effect, zvichiita kuti iwedzere kushanda kwedhaka.Zvinonyanya kukosha, inobatsirawo pakudzikisira kwakanyanya mukuoma kwedhaka, uye izvi zvinova zvinonyanya kutaurwa nepamusoro HEMC concentrations.
Pamusoro pekuwedzera kweHEMC kune musanganiswa wedhaka, kuderedzwa kwemarginal mu flexural simba kunoonekwa, nepo kune kuderera kwakanyanya kwesimba rekumanikidza.Iyo yekukotama reshiyo curve inoratidza yakakwira trajectory, zvichiratidza kuti HEMC yekuwedzera inowedzera kuoma kwedhaka.
Chinonyanya kukosha hunhu hweHEMC isimba rinonakidza rekuchengetedza mvura.Ichi chivakwa chinoshanda sechipinganidzo pakukurumidza kunyudzwa kwemvura nemhepo-yakadzidziswa kongiri mukupurasa dhaka zviitiko.Nekuda kweizvozvo, inova nechokwadi chekuti hydration ye simende mukati medhaka, zvichikonzera kusanganiswa kwedhaka uye kongiri yakavharwa nemhepo, nekudaro ichisimudza kusimba kwechisungo kusvika kumazinga akakwirira.
