Ngwa nke hydroxypropyl methylcellulose dị nnọọ ukwuu, na ọ nwere ọtụtụ ihe jikọrọ ya na viscosity ya, na viscosity chọrọ maka ojiji dị iche iche nke hydroxypropyl methylcellulose dịkwa iche, ya mere, mgbe anyị na-eji ngwaahịa ya Nke mbụ, anyị kwesịrị ịma ihe viscosity ya. bụ, ma viscosity nke hydroxypropyl methylcellulose na-emetụta ọtụtụ ihe.Ọ bụrụ na nchekwa ahụ kpacharaghị anya, ọ nwere ike ime ka viscosity ya daa.Ya mere, maka hydroxypropyl methylcellulose, Kedu ihe bụ viscosity ya metụtara?Ka m ewebata gị nkenke.
N'ozuzu, ihe ndị a ga-emetụta viscosity nke hydroxypropyl methylcellulose:
1. N'ịdị elu nke polymerization nke cellulose ether na ibu ibu molekụla, nke dị elu nke viscosity nke ngwọta mmiri ya;
2. Nke dị elu nke usoro onunu ogwu (ma ọ bụ ịta) nke cellulose ether, nke dị elu viscosity nke ngwọta mmiri ya, ma ekwesịrị iji nlezianya họrọ usoro ọgwụgwọ kwesịrị ekwesị mgbe ị na-eji ya, ka ọ ghara imetụta arụmọrụ nke ngwa agha na ihe ma ọ bụrụ na . usoro onunu ogwu di oke elu;
3. Dị ka ọtụtụ mmiri mmiri, viscosity nke cellulose ether ngwọta ga-ebelata na mmụba nke okpomọkụ, na elu nke ịta nke cellulose ether, ukwuu mmetụta nke okpomọkụ;
N'ozuzu, mgbe anyị na-achịkwa viscosity nke hydroxypropyl methylcellulose, anyị na-ahụ site na isi ihe ndị dị n'elu, n'ihi ya, anyị kwesịrị ịlele ma jiri ya ọtụtụ oge mgbe ị na-echekwa hydroxypropyl methylcellulose.
