Focus on Cellulose ethers

Hydroxyethyl methyl cellulose muaj zog

Feature 11 (1-6)

01
Solubility:
Nws yog soluble hauv dej thiab qee cov organic solvents. Nws tuaj yeem yaj hauv dej txias. Nws qhov siab tshaj plaws concentration tsuas yog txiav txim siab los ntawm viscosity. Solubility hloov nrog viscosity. Qhov qis dua qhov viscosity, qhov ntau dua qhov solubility.

02
ntsev kuj:
Cov khoom no yog non-ionic cellulose ether thiab tsis yog polyelectrolyte, yog li nws yog ib qho ruaj khov nyob rau hauv aqueous tov nyob rau hauv lub xub ntiag ntawm hlau ntsev los yog organic electrolytes, tab sis ntau ntxiv ntawm electrolytes yuav ua rau gelation thiab nag lossis daus.

03
Kev ua haujlwm saum npoo:
Vim yog lub ntsej muag ua haujlwm ntawm cov tshuaj aqueous, nws tuaj yeem siv los ua cov tshuaj tiv thaiv colloid, emulsifier thiab dispersant.

04
Thermal Gel:
Thaum cov khoom aqueous tov yog rhuab mus rau ib tug tej yam kub, nws ua opaque, gels, thiab ua ib tug precipitate, tab sis thaum nws yog tsis tu ncua txias, nws rov qab mus rau lub qub tshuaj lub xeev, thiab qhov kub ntawm xws li gelation thiab nag lossis daus tshwm sim feem ntau nyob ntawm seb. ntawm lawv cov lubricants. , ncua kev pab, tiv thaiv colloid, emulsifier, thiab lwm yam.

05
metabolism:
Metabolically inert thiab tsis muaj ntxhiab tsw thiab aroma, lawv tau dav siv nyob rau hauv cov zaub mov thiab tshuaj vim hais tias lawv tsis metabolized thiab muaj tsawg tsw thiab aroma.

06
Mildew kuj:
Nws muaj peev xwm ua tau zoo antifungal thiab zoo viscosity stability thaum lub sij hawm ntev cia.
