Sodium polyacrylate CAS 9003-04-7

Sodium polyacrylate bụ ntụ ntụ ọcha. Enweghị isi na enweghị ụtọ. Nnukwu hygroscopic. Ngwakọta polymer nwere hydrophilic na hydrophobic otu. Jiri nwayọọ soluble na mmiri na-etolite a nnọọ viscous transperent mmiri mmiri, na viscosity nke 0.5% ngwọta bụ banyere Pa•s, viscous na n'ihi na mmiri absorption ọzịza (dị ka CMC, sodium alginate) emepụtara, ma n'ihi na ionic onu nke ọtụtụ anionic iche iche n'ime molecule na-amụba molekụla yinye, na-arụ ọrụ nke ukwuu viscous ngwọta. Viscosity ya dị ihe dịka 15-20 ugboro nke CMC na sodium alginate. Ngwọta ikpo ọkụ, nnu na-anọpụ iche na acid organic nwere obere mmetụta na viscosity ya, ebe viscosity alkaline na-abawanye. A na-esighi ike na ihe mgbaze organic dị ka ethanol. Okpomọkụ siri ike ruo ogo 300 anaghị ere ere. Viscosity na-adịte aka na-agbanwe ntakịrị, ọ dịghị mfe imebi. N'ihi electrolyte, ọ na-enwe ike ịnweta acid na metal ion, na viscosity na-ebelata.
