Cellulose etherinogona kuvandudza mashandiro emota yakanyorova, uye chinhu chikuru chinokanganisa mashandiro emota. Kusarudzwa kwakanaka kwe cellulose ethers dzemhando dzakasiyana, viscosities dzakasiyana, saizi dzakasiyana dzezvimedu, madhigirii akasiyana ekusimba uye huwandu hwakawedzerwa zvichave nemhedzisiro yakanaka pakuvandudzwa kwebasa remota yakanyorova.
Kune hukama hwakanaka pakati pekuenderana kwe simende paste uye chiyero che cellulose ether. Cellulose ether inogona kuwedzera zvakanyanya viscosity yemortar. Kana chiyero chikuru, mhedzisiro yacho inoonekwa zvikuru. High-viscosity cellulose ether aqueous solution ine thixotropy yakawanda, inovawo hunhu hukuru hwe cellulose ether.
Kukora kwechinhu kunoenderana nehukuru hwepolymerization ye cellulose ether, huwandu hwemhinduro, shear rate, tembiricha nezvimwe. Hunhu hwe gelling hwemushonga uyu hwakasiyana nealkyl cellulose nezvimwe zvinogadzirwa nawo. Hunhu hwe gelation hunoenderana nehuwandu hwekutsiva, huwandu hwemhinduro nezvimwe zvinowedzerwa. Kune zvinogadzirwa ne hydroxyalkyl zvakagadziriswa, hunhu hwe gel hunoenderanawo nehuwandu hwekuchinja hwe hydroxyalkyl. 10%-15% solution inogona kugadzirirwa low-viscosity MC ne HPMC, 5%-10% solution inogona kugadzirirwa medium-viscosity MC ne HPMC, uye 2%-3% solution inogona kugadzirirwa chete high-viscosity MC ne HPMC. Kazhinji kupatsanurwa kwe viscosity ye cellulose ether kunoongororwawo ne 1%-2% solution.
Huremu hwakakura hwemamorekuruether ye celluloseine simba guru rekukora. Mapolymer ane huremu hwakasiyana hwemamorekuru ane viscosities dzakasiyana mumhinduro imwe chete yekukosha. Dhigirii repamusoro. Kukora kwacho kunogona kuwanikwa chete nekuwedzera huwandu hwakawanda hwe cellulose ether ine huremu hwakaderera hwemamorekuru. Kukora kwayo hakutsamiri zvakanyanya padanho rekuchekwa, uye kukora kwakakwirira kunosvika kukora kwakatarwa, uye huwandu hunodiwa hwekuwedzera hushoma, uye kukora kunoenderana nekushanda kwekukora. Naizvozvo, kuti uwane kugadzikana kwakati, huwandu hwakati hwe cellulose ether (kukora kwemhinduro) uye kukora kwemhinduro zvinofanira kuvimbiswa. Kupisa kwegel yemhinduro kunodererawo zvakanangana nekuwedzera kwekukora kwemhinduro, uye magel patembiricha yemumba mushure mekusvika pakukora kwakati. Kukora kwe HPMC kwe gelling kwakakwira zvakanyanya patembiricha yemumba.
