CHaracteristics nke HEC

1.Na-ejupụta

HEC bụ ezigbo thickener maka mkpuchi na ịchọ mma. N'ime ngwa ndị bara uru, nchikota nke nkwusioru na nkwusioru, nchekwa, dispersibility, na njigide mmiri ga-emepụta mmetụta dị mma karị.

2.Pseudoplasticity

Pseudoplasticity na-ezo aka na ihe onwunwe nke viscosity nke ngwọta na-ebelata na mmụba nke ọsọ. Agba Latex nwere HEC dị mfe itinye ya na brushes ma ọ bụ rollers ma nwee ike ịbawanye ịdị nro nke elu, nke nwekwara ike ịbawanye arụmọrụ ọrụ; shampoos nwere HEC nwere ezigbo mmiri ma dị nnọọ viscous, dị mfe itughari ma dị mfe ịgbasa.
