Abstract: Solution polymerization method was used to prepare hydrophilic antifogging acrylate resin. By means of comparison, the optimum synthesis technology conditions was obtained that ethyl acrylate was used as soft monomer , methylcrylate was used as hard monomer. The best functional monomers was acrylic acid and methyl acrylic acid. The accessory functional monoer was β-hydroxyl ethyl acrylate. Cross-linking agent methylol acrylamide belongs to self-cross-linking system. Crosslinker was N-hydroxymethyl acrylamide.The quality rate of cross-linking agent and carboxylic acid is 4 to 1 .The resin can be cured perfectly at the temperature of 100°C in 40 min. The prepared acrylate resin had excellent water-solubility and antifogging.

Abstract: Effects of electromagnetic filling parameters on Density of Al-Si alloy in low pressure casting were investigated. The key influential factors on Density of Al-Si Alloy were determined by orthogonal testing. The results show that the influential orders of electric current, magnetic inductivity and cyclic time on the density of the ZL114 alloy are as follows: electric current, then magnetic inductivity, and then cyclic time. Electric current and electromagnetic field can effectively improve the density of the ZL114 alloy in low pressure casting.
