Iselulosi yeHydroxyethyl
Yipolymer engeyiyo i-ionic yamanzi enyibilikayo, emhlophe okanye etyheli kancinane, umgubo oqukuqelayo ngokulula, ongenavumba kwaye awunancasa, unyibilika kuwo omabini amanzi abandayo nakumanzi ashushu, kwaye izinga lokunyibilika liyanda ngokunyuka kwamaqondo obushushu.Ukunganyibiliki kwizinyibilikisi eziphilayo.
Iipropati ze-hydroxyethyl cellulose:
1. I-HEO iyancibilika kumanzi ashushu okanye abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, ngoko inoluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gelation engekho-thermal.
2. I-non-ionic ngokwayo inokuhlalisana kunye nolunye uluhlu olubanzi lwezinye iipolymers ezinyibilikayo zamanzi, i-surfactants kunye neetyuwa, kwaye i-colloidal thickener egqwesileyo ye-high-concentration electrolyte solutions.
3. Umthamo wokugcinwa kwamanzi uphindwe kabini kunalowo we-methyl cellulose, kwaye unolawulo olungcono lokuhamba.
4. Xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose, ikhono lokusabalalisa i-HEC libi kakhulu, kodwa ikhono lokukhusela i-colloid linamandla.
