Makhalidwe a Hydroxyethyl Cellulose

Hydroxyethyl cellulose

Ndi polima yosungunuka m'madzi yopanda ionic, yoyera kapena yachikasu pang'ono, ufa wosavuta kuyenda, wopanda fungo komanso wopanda kukoma, wosungunuka m'madzi onse ozizira ndi madzi otentha, ndipo kuchuluka kwa kusungunuka kumawonjezeka ndi kuwonjezeka kwa kutentha.Insoluble mu organic solvents.

Makhalidwe a hydroxyethyl cellulose:

1. HEO imasungunuka m'madzi otentha kapena ozizira, ndipo sichimawotcha kutentha kwambiri kapena kuwira, choncho imakhala ndi mitundu yambiri ya solubility ndi viscosity, komanso gelation yopanda kutentha.

2. Zopanda ionic zokha zimatha kukhala pamodzi ndi ma polima ena osungunuka m'madzi, ma surfactants ndi mchere, ndipo ndi yabwino kwambiri ya colloidal thickener ya high-concentration electrolyte solutions.

3. Mphamvu yosungira madzi imakhala yowirikiza kawiri kuposa ya methyl cellulose, ndipo imakhala ndi malamulo oyendetsera bwino.

4. Poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, mphamvu yobalalika ya HEC ndiyoipa kwambiri, koma mphamvu yoteteza colloid ndiyo yamphamvu kwambiri.
