Hydroxyethyl cellulose bụ polima na-agbaze mmiri nke na-abụghị ionic nke e ji cellulose, ihe e ji emepụta polymer eke, mee site na usoro kemịkalụ dị iche iche. Ọ bụ ihe siri ike nke na-acha ọcha ma ọ bụ odo odo, nke na-enweghị isi na ụtọ, nke a pụrụ ịgbaze na mmiri oyi na mmiri ọkụ, ọnụego mgbaze na-abawanye ka okpomọkụ na-arị elu. N'ozuzu, ọ naghị agbaze na ọtụtụ ihe mgbaze organic. A na-eji ya dị ka ihe na-eme ka ihe sie ike na ihe na-eme ka ọ sie ike na agba latex. Ọ dị mfe ịgbasa na mmiri oyi na uru pH na-erughị 7 ma ọ bụ hà nhata, mana ọ dị mfe ịkpọkọta na mmiri alkaline, yabụ a na-akwadebe ya tupu oge eruo maka ojiji ma emechaa, ma ọ bụ mee mmiri acid na-adịghị ike ma ọ bụ ihe ngwọta organic ka ọ bụrụ slurry, enwere ike ịgwakọta ya na granular ndị ọzọ. A na-agwakọta ihe ndị e ji mee ya ọnụ.
Njirimara nke hydroxyethyl cellulose:
A na-agbaze HEC n'ime mmiri ọkụ ma ọ bụ mmiri oyi, ọ naghịkwa agbapụta n'oge okpomọkụ dị elu ma ọ bụ mgbe ọ na-esi mmiri, nke na-eme ka o nwee ọtụtụ njirimara ịgbaze na viscosity, yana njikọta na-abụghị okpomọkụ.
Ọ nwere ike ibikọ na ọtụtụ polymers ndị ọzọ na-agbaze mmiri, surfactants, na nnu, ọ bụkwa ezigbo ihe na-eme ka colloidal sie ike maka ngwọta nwere electrolytes dị elu.
Ike nchekwa mmiri dị okpukpu abụọ karịa nke methyl cellulose, ọ na-achịkwakwa mmiri nke ọma.
Ma e jiri ya tụnyere methyl cellulose na hydroxypropyl methyl cellulose a ma ama, ikike ịgbasa nke HEC bụ nke kacha njọ, mana ikike nchekwa colloid bụ nke kachasị ike.
Ọdịdị ya dị mma nke ukwuu; o nwere uru dị na ịchekwa ọrụ, ọ dịghị mfe ịfụ mmiri, mgbochi sag, ezigbo mgbochi ịgbasa mmiri, wdg.
Ndakọrịta dị mma na ọtụtụ surfactants na ihe nchekwa eji eme ihe na agba latex.
Ọdịiche nchekwa ahụ siri ike, nke nwere ike igbochi hydroxyethyl cellulose izugbe ibelata viscosity nke agba latex n'oge nchekwa n'ihi mmebi nke enzymes.
