Kedu ihe bụ Carbomer 980 nwere CAS 54182-57-9

Carbomer bụ ntụ ntụ ọcha rụrụ arụ, nwere acidity, hygroscopicity na obere ísì pụrụ iche.Enwere ike igbari ya na mmiri, ethanol na glycerol.Ngwakọta ahụ nwere 56% - 58% carboxyl otu, ya mere ọ na-esighi ike acidic.Mgbe carbomer na-agbasasị na mmiri, n'ihi nchụso n'etiti ebubo na-adịghị mma nke ionization carboxyl kpatara, polymer crimped na-agbatị ma gbasaa na olu.The pH nke 0.5% aqueous mgbasa bụ 2.7 ~ 3.5.1% aqueous dispersion nwere ike neutralized na alkaline bekee na-etolite jel.Nleta nke mgbasa mmiri nke a na-ejikarị eme ihe bụ 0.1% - 3.0%.
