摘要
研究了硅溶胶中不同SiO_(2)含量对涂料、型壳性能和铸件污染层的影响。结果表明:相同粉液比情况下,涂料的粘度和涂层厚度随着SiO_(2)含量的增加而增大;当SiO_(2)含量增加至14%时,涂料粘度急剧增大,随着SiO_(2)含量的增加,面层型壳抗弯强度逐步增大,铸件的表面污染层厚度随着SiO_(2)含量的增大和铸件厚度的增大均呈现上升趋势。
The effect of SiO_(2)content in silica sol on the properties of coating,shell and surface contaminated layer of castings was studied.The results showed that the viscosity and thickness of the coating increases with the increase of SiO_(2)content at the same powder-liquid ratio,and the viscosity of the coating increases sharply when the SiO_(2)content increased to 14%.With the increase of SiO_(2)content,the flexural strength of surface shell increased gradually.The thickness of contaminated layer on the surface of castings increased with the increase of SiO_(2)content and thickness of castings.
