摘要
基于古代焚失法,以石膏型面层与加固层替代传统泥范来制备天然植物金属艺术品。结果表明,以50%的α型半水石膏和50%铝矾土作为基体材料,加80%的硫酸亚铁和20%的焦磷酸钠混合溶液作为添加剂配制成的浆料,制得的石膏型显微结构较松散,能降低型壳强度,提升破壳效果;加50%的硅溶胶作为粘结剂配制成的浆料,制得的石膏型显微结构出现三维网状结构,能提高石膏加固层抗弯和抗拉强度,阻止铸型的变形和开裂。所制备铸件造型逼真。
Based on the ancient lost-in-fire method,the natural plant metal artworks were prepared by using gypsum surface layer and reinforcement layer instead of traditional clay.The results show that the slurry prepared with 50%α-hemihydrate gypsum and 50%bauxite as matrix materials and 80%ferrous sulfate and 20%sodium pyrophosphate as additives presents loose microstructure,which can reduce the strength of the shell and improve the broken shell effect.The slurry prepared with 50%silica sol as binder has three-dimensional network structure,which can improve the bending and tensile strength of the gypsum reinforcement layer and prevent the cracking and deformation of the mold.Finally,the casting has the characteristics of realistic modeling and unique.
