Dab tsi yog qhov sib txawv ntawm hydroxyethyl cellulose thiab cellulose cellulose

Coob tus neeg tsis tuaj yeem qhia qhov sib txawv ntawm hydroxyethyl cellulose thiab tshuaj cellulose. Hydroxyethyl cellulose thiab cov cellulose yog ob yam tshuaj sib txawv. Lawv muaj cov yam ntxwv hauv qab no.

1
Hydroxyethyl cellulose:
Raws li cov tsis-ionic surfactant, ntxiv rau thickening, khi, ua yeeb yaj kiab, ua yeeb yaj kiab, nws kuj muaj cov khoom hauv qab no:
1. HEC yog Soluble hauv dej kub lossis dej txias, ua rau nws muaj dej sov lossis npau npau, thiab cov yam ntxwv uas tsis yog-thermal gelation;
2. Nws yog tsis-ionic thiab tuaj yeem ua ke nrog ntau yam dej-solfactaners polymers, thiab yog ib tug zoo colloidal thickener muaj siab electrolyte kev daws teeb meem;
3
4. Piv nrog lees paub methyl cellulose thiab hydroxypropyl cellulose, lub zog impersing ntawm HEC yog qhov phem tshaj, tab sis kev tiv thaiv kev tiv thaiv muaj zog tshaj.

2
Ethyl Cellulose
Nws yog cov tsis-ionic cellulose ionetle uas yog insoluble hauv dej tab sis soluble hauv cov kuab tshuaj organic. Nws muaj cov yam ntxwv hauv qab no:

1. Tsis yooj yim hlawv.
2. Zoo thermal stability thiab zoo heev thermoplastic.
3. Tsis muaj kev tshem tawm lub hnub ci.
4. Kev hloov pauv tau zoo.
5. Cov khoom Dielectric zoo.
6. Nws muaj zoo alkali tsis kam thiab qaug zog acid tiv taus.
7. Kev ua tau zoo los tiv thaiv kev ua haujlwm.
8. Zoo tsis kam rau ntsev, txias thiab noo noo nqus.
9. Ruaj khov rau cov tshuaj lom neeg, lub sij hawm ntev cia tsis muaj qhov tsis zoo.
10. Tau tshaj ntau lub resins thiab zoo sib xws nrog txhua tus tshuab yas.
11. Nws yog qhov yooj yim kom hloov xim hauv qhov chaw muaj zog alkaline thiab cua sov.
