AI Technical Summary
Existing silica aerogel powder is unevenly dispersed in gypsum board and tends to float, which leads to a decrease in bonding performance, affects the strength and heat insulation effect of the board, and the dispersion process is complex and costly, making it difficult to achieve continuous production.
Silica aerogel with a particle size of 0.425 mm to 0.6 mm and a specific surface area of 400 m2/g to 600 m2/g was used, and a specific multi-stage variable speed stirring and feeding program was combined to ensure the efficient and uniform dispersion of aerogel powder in water, so as to prepare silica aerogel slurry.
It enables rapid dispersion of silica aerogel in water, improves the strength and thermal insulation effect of gypsum board, simplifies the dispersion process, reduces production costs, and supports continuous production.
