Hydroxyethyl cellulose (HEC) bụ ọcha ma ọ bụ na-acha odo odo, enweghị isi, ntụ ntụ na-adịghị egbu egbu. A na-akwado ya site na cellulose bụ isi na ethylene oxide (ma ọ bụ chloroethane) site na etherification. Ọ bụ cellulose ether soluble na-abụghị ionic. N'ihi na HEC cellulose nwere ezigbo àgwà nke ndim, nkwusioru, mgbasa, emulsification, adhesion, film e guzobere, nchebe nke mmiri, na nchebe nke colloids, ọ na-ọtụtụ ebe na-eji mmanụ ala mmịpụta, coatings, ewu, ọgwụ na nri, textiles, papermaking, na ubi ndị ọzọ.
Ngwa:
1. Hydroxyethyl cellulose ntụ ntụ nwere ike gbazee na mmiri ọkụ na mmiri oyi, ọ gaghịkwa agbaze mgbe ọkụ ma ọ bụ sie ya. N'ihi nke ahụ, ọ nwere ọtụtụ ihe solubility na njirimara viscosity na enweghị thermogelability.
2. HEC nwere ike ibikọ ọnụ na polymers ndị ọzọ na-edozi mmiri, surfactants, na salts. HEC bụ ọmarịcha colloidal thickener nwere ihe ngwọta dielectric dị elu.
3. Ike njigide mmiri ya dị okpukpu abụọ dị elu karịa nke methylcellulose, ọ nwekwara usoro nhazi nke ọma.
4. Tụnyere methylcellulose na hydroxypropylmethylcellulose, HEC nwere ike colloid nchebe kachasị ike.
Ụlọ ọrụ ihe owuwu: Enwere ike iji HEC mee ihe dị ka ihe na-ejide mmiri na ihe mgbochi ntọala ciment.
Ụlọ ọrụ na-egwupụta mmanụ: Enwere ike iji ya dị ka ihe na-esi ísì na cementing maka mmiri na-arụ ọrụ nke ọma mmanụ. Mmiri mmiri na-egwupụta ihe na HEC nwere ike imeziwanye nkwụsi ike nke mkpọ ala dabere na ọrụ ọdịnaya siri ike dị ala.
Ụlọ ọrụ mkpuchi mkpuchi: HEC nwere ike ịrụ ọrụ n'ịgba, emulsifying, gbasaa, ịkwado na idowe mmiri maka ihe latex. A na-eji mmetụta dị ịrịba ama na-akpụ akpụ, ezigbo agba agba agba, mmepụta ihe nkiri, na nkwụsi ike nchekwa.
