Mushure mekuwedzera hydroxypropyl methylcellulose kune simende-yakavakirwa zvinhu, inogona kukora.Huwandu hwehydroxypropyl methylcellulose inotaridza kudiwa kwemvura yesimende-yakavakirwa zvinhu, saka zvinokanganisa kubuda kwedhaka.
Zvinhu zvinoverengeka zvinokanganisa viscosity yehydroxypropyl methylcellulose:
1. Iyo yakakwirira dhigirii yepolymerization ye cellulose ether, iyo yakakura huremu hwema molecular, uye yakakwirira viscosity yemushonga wemvura;
2. Iyo yakakwirira yekutora (kana kusungirirwa) kwe cellulose ether, iyo yakakwirira viscosity yeaqueous solution yayo.Nekudaro, zvinodikanwa kuti utarise pakusarudza iyo yakakodzera kutora panguva yekunyorera kuti usapinda zvakanyanya, izvo zvinokanganisa basa redhaka uye kongiri.characteristic;
3. Sezvinoita zvinwiwa zvakawanda, viscosity ye cellulose ether solution inodzikira nekuwedzera kwetembiricha, uye iyo yakanyanya kuwanda kwe cellulose ether, kunowedzera simba rekushisa;
4. Hydroxypropyl methylcellulose solution inowanzova pseudoplastic, iyo ine pfuma yeshear thinning.Iyo yakakura iyo shear rate panguva yekuedzwa, iyo yakaderera iyo viscosity.
Nokudaro, kubatanidzwa kwedhaka kuchaderera nekuda kwesimba rekunze, iro rinobatsira pakutsvaira kuvakwa kwedhaka, zvichiita kuti zvive zvakanaka kushanda uye kubatana kwedhaka panguva imwe chete.
Iyo hydroxypropyl methylcellulose mhinduro icharatidza Newtonian fluid maitiro apo iyo yekumisikidza yakadzikira uye viscosity yakaderera.Kana iyo yekuisa pfungwa ichiwedzera, mhinduro inozoratidza zvishoma nezvishoma pseudoplastic fluid maitiro, uye iyo yakakwira iyo yekumisikidza, iyo inonyanya kuoneka iyo pseudoplasticity.
