Hydroxyethyl cellulose
Nws yog non-ionic dej-soluble polymer, dawb los yog daj me ntsis, yooj yim-ntws hmoov, tsis muaj ntxhiab thiab tasteless, soluble nyob rau hauv ob qho tib si dej txias thiab dej kub, thiab cov dissolution tus nqi nce nrog rau qhov kub thiab txias.Insoluble hauv cov kuab tshuaj organic.
Cov khoom ntawm hydroxyethyl cellulose:
1. HEO soluble nyob rau hauv dej kub los yog txias, thiab tsis precipitate ntawm kub los yog boiling, yog li nws muaj ib tug ntau yam ntawm solubility thiab viscosity yam ntxwv, raws li zoo raws li tsis-thermal gelation.
2. Lub non-ionic nws tus kheej tuaj yeem ua ke nrog ntau yam ntawm lwm cov dej-soluble polymers, surfactants thiab ntsev, thiab yog ib qho zoo heev colloidal thickener rau high-concentration electrolyte daws.
3. Lub peev xwm tuav dej yog ob zaug siab dua li ntawm methyl cellulose, thiab nws muaj kev tswj xyuas zoo dua.
4. Piv nrog rau kev lees paub methyl cellulose thiab hydroxypropyl methyl cellulose, lub peev xwm dispersing ntawm HEC yog qhov phem tshaj, tab sis lub peev xwm tiv thaiv colloid yog qhov muaj zog tshaj.
