Katundu wa Hydroxyethyl Cellulose

Hydroxyethyl cellulose

Ndi polima yosasungunuka m'madzi, yoyera kapena yachikasu pang'ono, ufa woyenda mosavuta, yopanda fungo komanso yopanda kukoma, yosungunuka m'madzi ozizira komanso m'madzi otentha, ndipo kuchuluka kwa kusungunuka kumawonjezeka kutentha kukakwera. Yosasungunuka mu zosungunulira zachilengedwe.

Katundu wahydroxyethyl cellulose:

1. HEO imasungunuka m'madzi otentha kapena ozizira, ndipo siuma pa kutentha kwambiri kapena kuwira, kotero imakhala ndi mitundu yosiyanasiyana ya kusungunuka ndi kukhuthala, komanso gelation yosatentha.

2. Chosagwiritsa ntchito ma ionic chokha chingathe kukhala pamodzi ndi ma polima ena ambiri osungunuka m'madzi, ma surfactants ndi mchere, ndipo ndi chokhuthala chabwino kwambiri cha colloidal cha mayankho a electrolyte okhala ndi kuchuluka kwakukulu.

3. Mphamvu yosungira madzi ndi yowirikiza kawiri kuposa ya methyl cellulose, ndipo ili ndi kayendedwe kabwino ka madzi.

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