摘要
介绍了 2种增强型快干硅溶胶FS Ⅱ ,FS Ⅲ ,其制壳层间干燥时间可缩短到 1~ 2h。其中FS Ⅲ增强快干硅溶胶在型壳干燥速度和型壳性能上相当先进。讨论了增强快干机理 。
Two kinds of enhanced fast drying colloidal silica, FS Ⅲ and FS Ⅱ, were introduced and the drying period between dip coat can be reduced to 1~2 h, of which the shell drying rate and shell performance of FS Ⅲ were relatively excellent. The mechanism of fast enhancement of shell processing was discussed and the parameters of shell making and their application were presented.
