Cov teebmeem kub ntawm Hydroxy Ethyl Cellulose Solution

Hydroxy Ethyl Cellulose (HEC) yog cov dej-soluble polymer uas tau siv dav hauv ntau yam lag luam xws li tshuaj pleev ib ce, tshuaj, thiab zaub mov ua cov thickener, binder, thiab stabilizer. Lub viscosity ntawm HEC cov kev daws teeb meem yog nyob ntawm qhov kub thiab txias, thiab kev hloov ntawm qhov kub tuaj yeem cuam tshuam rau lub cev ntawm cov tshuaj.

Thaum qhov kub ntawm cov tshuaj HEC nce, qhov viscosity ntawm cov tshuaj txo qis vim qhov txo qis hauv hydrogen bonding ntawm cov saw hlau polymer. Qhov kev txo qis hauv viscosity no tau tshaj tawm ntawm qhov kub siab dua thiab ua rau cov kua dej ntau dua.

Hloov pauv, thaum qhov kub ntawm cov tshuaj HEC txo qis, qhov viscosity ntawm cov tshuaj nce ntxiv vim muaj cov hydrogen sib txuas ntxiv ntawm cov saw hlau polymer. Qhov kev nce hauv viscosity no tau tshaj tawm ntawm qhov kub qis dua thiab ua rau muaj cov kua qaub ntau dua, zoo li gel.

Tsis tas li ntawd, kev hloov pauv ntawm qhov kub thiab txias tuaj yeem cuam tshuam qhov solubility ntawm HEC hauv dej. Thaum qhov kub thiab txias, HEC ua ntau dua nyob rau hauv dej, thaum nyob rau hauv qis kub, HEC yuav tsawg soluble nyob rau hauv dej.

Zuag qhia tag nrho, qhov cuam tshuam ntawm qhov kub thiab txias ntawm HEC cov tshuaj yog nyob ntawm qhov concentration ntawm cov polymer, qhov xwm txheej ntawm cov kuab tshuaj, thiab cov ntawv thov tshwj xeeb ntawm HEC cov tshuaj.
