Study of Pre-Dispersive Technology of Brucite Fiber and the Composite Insulation Board

Abstract:

This paper has compared different kinds of dispersive technologies for brucite fiber mineral, and researched the industrial application of composite insulation board. Compared with the ball-milling treatment and the ultrasonic disperser craft techniques, the high speed mechanical stirring is preferential. The dispersive degree of three dispersants shows a trend as OT > FDN > PCA ®(IV), and the system of suspension with OT penetrant is stable under the designed ratios. The optimal fabrication progress is as the ratio of water and fiber is 18:1, the dosage of OT is 15 wt.% of brucite fiber, the stirring time is 60 min, and the stirring speed is 1200 r/min. Whit the appropriate dosage of brucite fiber (down to 15 wt.% of total fibers mass ) can improve the pore structure of the insulation board, which is benefit to the thermal insulation properties. The results revealed that the brucite fiber could partially replace chrysotile fibers in the composition of insulation board.
