AEROGEL BLANKET FOR ULTRA-HIGH TEMPERATURES, METHOD FOR MANUFACTURING SAME AND CONSTRUCTION METHOD THEREOF

摘要

The present invention relates to a hydrophilic silica aerogel blanket for ultra-high temperature insulation, a production method thereof, and a construction method thereof. More specifically, the present invention provides a production method a hydrophilic silica aerogel blanket, the method capable of strengthening the structure of a silica gel by adding a basic catalyst in an aging step, reducing processing time and cost by omitting a surface modification step, thereby reducing manufacturing cost, and suppressing the generation of a bad odor during construction by fundamentally blocking a volatile organic compound (VOC), a hydrophilic silica aerogel blanket produced thereby, and a construction method of a hydrophilic silica aerogel blanket, the method capable of suppressing the generation of a bad odor when constructing the hydrophilic aerogel blanket on an ultra-high temperature piping equipment, and at the same time, preventing the loss of heat insulation performance due to moisture in the air.
