Izakhiwo ze-hydroxyethyl cellulose

IHydroxYethyl Cellulose

I-polymer engenazona nje yokuncibilikisa amanzi, emhlophe noma ephuzi kancane, i-powder egeleza kancane, engenamzimba futhi ayinambitha, incibilika emanzini abandayo namanzi ashisayo, futhi izinga lokuchithwa likhuphuka ngokwanda kokushisa. Insoluble ku-organic solvents.

Izakhiwo ze-hydroxyethyl cellulose:

1. UHeo uyanyibilika emanzini ashisayo noma abandayo, futhi awenzi okushisa okuphezulu noma ukubilisa, ngakho-ke kunobuningi be-soubity kanye ne-viscosity, kanye ne-gelation engeyona eye-thermal.

I-3. Umthamo wokugcina amanzi uphakeme kabili njenge-methyl cellulose, futhi inomthethonqubo ongcono wokugeleza.

4. Uma uqhathanisa ne-methyl cellulose ye-methyl kanye ne-hydroxypropylm methyl celtule, amandla asabalalisayo ka-HEC yimbi kakhulu, kepha ikhono le-colloid elivikelayo linamandla.
