Izici ze-Hydroxyethyl Cellulose

I-Hydroxyethyl cellulose

I-polymer engeyona i-ionic emanzini encibilika, emhlophe noma ephuzi kancane, impushana egeleza kalula, ayinaphunga futhi ayinambitheki, inyibilika kuwo womabili amanzi abandayo namanzi ashisayo, futhi izinga lokuncibilika liyakhula ngokwenyuka kwezinga lokushisa.Ayincibiliki kuma-organic solvents.

Izici ze-hydroxyethyl cellulose:

1. I-HEO iyancibilika emanzini ashisayo noma abandayo, futhi ayidli ngokushisa okuphezulu noma ukubilisa, ngakho-ke inohlu olubanzi lwezimpawu ze-solubility kanye ne-viscosity, kanye ne-gelation engashisi.

2. I-non-ionic ngokwayo ingahlala kanye nohlu olubanzi lwama-polymers ancibilikayo emanzini, ama-surfactants nama-salts, futhi iyi-colloidal thickener enhle kakhulu yezixazululo ze-electrolyte eziphezulu zokugxila.

3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunalowo we-methyl cellulose, futhi unokulawula ukugeleza okungcono.

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