凝胶剂

Transmission Electron Microscope and other properties testing results show that the complex emulsifier system is the crucial influence factor of the polymerization process and the properties of products. It may influence the coagulum content and reaction rate of the polymerization process, the performance, particle diameter,viscosity, electrolyte stability and storage stability of the emulsion products and the contact angle of the film.The initiator mainly influences the coagulum content and reaction rate.The acrylic monomers mainly influence the solid content, Minimum Film Formation Temperature of the emulsion and the Glass Transition Temperature of the film.The organic silicone monomer mainly influences the water absorption of the film.The reaction temperature mainly influences the reaction rate and conversion.The stirring intensity mainly influences the coagulum content of the polymerization process.

Chitosan had been modified by polyacrylate sodium, glularaldehyde, and NaBH4, respectively, which afforded three kinds modified chitosan: polyacrylate sodium modified chitosan (CIS- PA4) chitosan bead and pentamethylene diamido crosslinked chitosan bead (CTSB- G- Hy). The adsorption properties of CTS-CTSB and CTSB-G-Hy were studied by L25(56) orthogonal experimental design. They show high adsorption activities for Pb2+ in solution. The highest removal efficiency of Pb2+ for CTS-PA4, CTSB and CTSB-G-Hy is 94%, 96% and 93%, respectively. The results showed the adsorption property of CTSB is the highest. The CTSB- G- Hy has good mechanical property, acid-resistance and alkali-resistance.
