Cellulose ether inowanzo kuve chinhu chakakosha mumamortars akasanganiswa nevhu rakaoma. Nekuti chinhu chakakosha chekuchengetedza mvura chine hunhu hwakanaka hwekuchengetedza mvura. Hunhu uhwu hwekuchengetedza mvura hunogona kudzivirira mvura iri mumamortars akanyorova kuti isatsvedze nguva isati yakwana kana kuti inyudzwe nesubstrate, kuwedzera nguva yekushanda kwemamortars akanyorova, kuve nechokwadi chekuti simende yanyorova zvakakwana, uye nekudaro pakupedzisira kuve nechokwadi chehunhu hwemumortars, izvo zvinonyanya kubatsira pakuvaka mortars dzakatetepa (dzakadai semartars ekupurasita) uye mortars musubstrates dzinonyudza mvura zvakanyanya (dzakadai semabhuroko ekongiri ane mhepo), tembiricha yakakwira uye mamiriro ekunze akaoma.
Hunhu hwekuchengetedza mvura hwe cellulose hune chekuita zvakanyanya nekusimba kwayo. Kana viscosity ye cellulose ether yakakwira, zvinoita kuti kuchengetedza mvura kuve nani. Viscosity ndiyo parameter yakakosha yekushanda kweMC. Parizvino, vagadziri veMC vakasiyana vanoshandisa nzira dzakasiyana uye zvishandiso kuyedza viscosity yeMC, uye nzira huru ndiHaake Rotovisko, Hoppler, Ubbelohde naBrookfield. Pachigadzirwa chimwe chete, viscosity inoyerwa nenzira dzakasiyana inosiyana zvikuru, uye dzimwe dzakatosiyana zvakanyanya. Saka, pakuenzanisa viscosities, zvakakosha kuita izvozvo pakati penzira dzakafanana dzekuedza, kusanganisira tembiricha, rotor, nezvimwewo.
Kazhinji, kana viscosity yakakwira, zvinoita kuti mvura irambe ichichengetwa zvakanaka. Zvisinei, kana viscosity yakakwira, ndipo panowedzera huremu hweMC uye kuderera kwekunyungudika kwayo, izvo zvine mhedzisiro yakaipa pakusimba uye mashandiro ekuvaka kwemota. Kana viscosity yakakwira, ndipo panonyanya kuoneka kuti mhedzisiro yekukora kwemota yacho iri pachena. Kana viscosity yakakwira, ndipo panonyanya kunamira mota yacho, mukuvaka, sezvinoratidzwa ne sticky scraper uye kunamatira kwakanyanya kune substrate. Zvisinei, hazvibatsire zvakanyanya kuwedzera simba rekuvaka kwemota yacho. Kana zvese zviri zviviri zvakavakwa, zvinoratidza kuti anti-sagging performance haisi pachena. Kusiyana neizvi, mamwe ma viscosity akaderera kusvika pakati asi akagadziriswa methyl cellulose ethers ane mashandiro akanaka mukuvandudza simba rekuvaka remota yacho.
