Attapulgite Clay

A novel poly(2-acrylamido-2-methylpropa-nesulfonicacid-co-acrylamide) / attapulgite (P(AMPS-co-AM)/APT) high-salt superabsorbent composite was synthesized through graft polymerization in aqueous solution by microwave irradiation. The structure of the composite was characterized by infrared spectra (FTIR).The influence of the content of monomer, microwave power and the ratio of attapulgite clay on water absorbency was investigated. The swelling behaviors and the water retention of Superabsorbent resin with different APT content were also examined. The results show that the graft copolymerization took place between APT and organic monomers. Adding an appropriate amount of APT in resin can effectively improve the absorption capacity and salt-water performance. Microwave power is 390W, APT amount is 7.5% (mass fraction),The water absorbency of resin in distilled water and 0.9wt% NaCl were 1460g / g and 114 g / g. The resin has a faster absorption rate and strong water retention, the appropriate increase the amount of APT can significantly speed up the rate of the resin absorbent and improve its water retention.

Sol Stability

AbstractThe effects of simultaneous additions of electrolyte and peptiser to dispersions of the synthetic hectorite-like clay, Laponite, have been studied. It has been unexpectedly discovered that whereas many cations cause gelling and flocculation of the dispersions as expected by colloid chemical theory, some cations actually stabilize the sols obtained with peptiser. A relationship has been found between the effectiveness of the cations in increasing sol stability and their size and charge.The effects of time, temperature and peptiser concentration have also been examined, and explanations are offered for the phenomena observed.
