摘　　要：介绍了新型快干硅溶胶,可使型壳层间干燥时间缩短到 1h^2h,并且具有很高湿强度时,高温强度和残留强度与硅酸乙酯相当。而且在型壳性能、制壳速度上已全面接近国际优质快干硅溶胶水平。A new kind of quick-draying ludox is introduced to shorten the interlayer drying time of shells to 1-2 hours. It has high-temperature strength and residual strength equivalent to silester. What's more, the performance of the shells and the shell making speed has completely approached to the international level of high-quality quick-drying ludox.
