Sodium polyacrylate CAS 9003-04-7

Sodium polyacrylate ndi ufa woyera. Zopanda fungo komanso zosakoma. Kwambiri hygroscopic. Gulu la polima lomwe lili ndi magulu a hydrophilic ndi hydrophobic. Pang'onopang'ono sungunuka m'madzi kupanga viscous kwambiri mandala zamadzimadzi, mamasukidwe akayendedwe a 0,5% yankho ndi za Pa • s, viscous ndi chifukwa cha madzi mayamwidwe kutupa (monga CMC, sodium alginate) opangidwa, koma chifukwa cha chodabwitsa ionic ambiri anionic magulu mkati molekyulu kuonjezera maselo mawonekedwe a viscous unyolo ndi viscous ntchito kwambiri. Kukhuthala kwake kuli pafupifupi nthawi 15-20 kuposa CMC ndi sodium alginate. Kuwotcha mankhwala, mchere wosalowerera ndale ndi organic zidulo ali ndi mphamvu pang'ono mamasukidwe ake mamasukidwe akayendedwe, pamene kukhuthala kwa zamchere kumawonjezeka. Insoluble mu organic solvents monga Mowa. Kutentha kwamphamvu mpaka madigiri 300 sikuwola. Kukhuthala kwa nthawi yayitali kumasintha pang'ono, osati kosavuta kuipitsa. Chifukwa cha electrolyte, amatha kutenga ayoni acid ndi zitsulo, ndipo mamasukidwe ake amachepetsedwa.
