Cov Khoom ntawm Hydroxyethyl Cellulose

Hydroxyethyl cellulose

Nws yog ib qho polymer uas tsis yog ionic yaj hauv dej, dawb los yog daj me ntsis, hmoov yooj yim ntws, tsis muaj ntxhiab thiab tsis qab, yaj tau hauv dej txias thiab dej kub, thiab tus nqi yaj nce ntxiv raws li qhov kub nce. Tsis yaj hauv cov kuab tshuaj organic.

Cov khoom ntawmhydroxyethyl cellulose:

1. HEO yaj tau hauv dej kub lossis dej txias, thiab tsis ua rau kub lossis npau, yog li nws muaj ntau yam solubility thiab viscosity, nrog rau cov gelation tsis yog thermal.

2. Cov non-ionic nws tus kheej tuaj yeem nyob ua ke nrog ntau yam polymers, surfactants thiab ntsev uas yaj hauv dej, thiab yog ib qho khoom siv colloidal thickener zoo heev rau cov kua electrolyte uas muaj concentration siab.

3. Lub peev xwm khaws dej tau ob npaug ntawm methyl cellulose, thiab nws muaj kev tswj hwm dej zoo dua.

4. Piv nrog rau cov methyl cellulose thiab hydroxypropyl methyl cellulose uas tau lees paub, lub peev xwm ntawm HEC yog qhov phem tshaj plaws, tab sis lub peev xwm tiv thaiv colloid yog qhov muaj zog tshaj plaws.
