Hydroxyethyl cellulose
Nws yog cov dej tsis-ionic-soluble polymer, dawb lossis me ntsis hmoov av, solub, solub, solub, thiab dej sov, thiab dej kub nce ntxiv nrog qhov kub thiab txias. Insoluble hauv cov kuab tshuaj organic.
Cov khoom ntawm hydroxyethyl cellulose:
1. Heo yog dej solub hauv dej kub lossis dej txias, thiab tsis yog nag lossis rhaub, yog li nws muaj ntau yam ntawm solubility thiab viscosity dab tsi uas tsis-thermal gelation.
2. Lub ionic nws tus kheej muaj peev xwm ua rau muaj lwm yam dej polymle, solfactants thiab ntsev zoo heev rau cov kev daws teeb meem electrolyte elects.
3
4. Piv nrog lees paub methyl cellulose thiab hydroxypropal methylropy, lub dispersing muaj peev xwm ntawm hac yog qhov phem tshaj, tab sis kev tiv thaiv kev tiv thaiv kev muaj peev xwm yog qhov muaj zog tshaj.
