硅溶胶与硅酸乙酯复合型壳探讨——缩短硅溶胶制壳周期方法之一

Investigation on Composite Ceramic Shell Bonded with Silica Sol and Ethyl Silicate ——One of the Methods Shortening the Period of Shell Making with Silica Sol

探讨用硅溶胶与硅酸乙酯制造复合型壳的工艺，选择出层间干燥时间等参数，为生产使用提供了科学依据。复合型壳代替硅溶胶型壳可大大缩短制壳生产周期。

The technology for making composite ceramic shell bonded with silica sol and ethyl silicate was studied. The drying time between dips and other factors of shell making were selected, which provides the scientific basis for the application of composite shell. The production period will be shorten with composite shell to replace silica sol shell.
