Research of Water-absorbing Mechanisms of the Proof Salt Super Water-absorbent Composite for the Silica Gel-carboxymethyl Cellulose Inarch Poly (Acrylic Acid) Salt WANG Yong 1,LI Ming 1,WAN Tao 2 (1. School of Materials Science and Engineering,Wuhan University of Technology,Wuhan 430070,China;2. Biomedical Materials and Engineering Research Center, Wuhan University of Technology,Wuhan 430070,China)Taking advantage of proof salt and high hydrophilic property of the silica gel and the carboxymethyl cellulose inarch poly (acrylic acid )salt of the super water-absorbent resin recombination,this paper made use of the water-absorbent composite form the inorganic polymer, sequentially advanced water-absorbent velocity and capacity of polymer water-absorbent resin in the brine.The water-absorbent property of composite was studied, the composite superficial mechanism was observed by the scanning electron microscope, fringe analyse and it was discussed that water-absorbent mechanism of the proof salt super water-absorbent composite for the silica gel-carboxymethyl cellulose inarch poly(acrylic acid) salt.silica gel; polymer water-absorbent resin; composite; proof salt
