Izakhiwo ze-Hydroxyethyl Cellulose

I-Hydroxyethyl cellulose

Iyi-polymer engeyona i-ionic encibilikayo emanzini, emhlophe noma ephuzi kancane, egeleza kalula, ayinaphunga futhi ayinambitheki, incibilika emanzini abandayo nasemanzini ashisayo, futhi izinga lokuncibilika liyanda ngokuphakama kwezinga lokushisa. Ayincibiliki ezinyibilikisini eziphilayo.

Izakhiwo zei-hydroxyethyl cellulose:

1. I-HEO iyancibilika emanzini ashisayo noma abandayo, futhi ayivuthi uma izinga lokushisa eliphezulu noma libila, ngakho-ke inezici eziningi zokuncibilika kanye nokuthamba, kanye ne-gelation engashisi.

2. I-non-ionic ngokwayo ingahlala ndawonye nezinye izinhlobo eziningi zama-polymer ancibilika emanzini, ama-surfactants kanye nosawoti, futhi iyisithako esihle kakhulu se-colloidal sezixazululo ze-electrolyte ezigxile kakhulu.

3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunowe-methyl cellulose, futhi unokulawulwa okungcono kokugeleza kwamanzi.

4. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa ikhono lokuvikela i-colloid yilona elinamandla kakhulu.
