SUPERCRITICAL DRYING METHOD FOR SILICA WET GEL BLANKET

摘要

The present invention relates to a supercritical drying method of a silica wet gel blanket and a method for producing a silica aerogel blanket including the same, the supercritical drying method preventing a salt from being accumulated inside a facility during supercritical drying.;According to the supercritical drying method of the present invention, by preventing a salt from being accumulated inside a facility during supercritical drying, it is possible to improve the operation stability of a supercritical drying process.;In addition, according to the supercritical drying method of the present invention, since only a line filter may be separated and easily washed, the amount of time required for washing and the amount of ammonia wastewater generated therefrom may be reduced, thereby improving efficiency and reducing costs.
