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.

In the paper the results of an experimental program intended to determine factors influencing the impact resistance of the External Thermal Insulation Composite Systems (ETICS) were presented. For the research the systems based on polystyrene have been chosen. The insulation material was faced with a rendering consisting of base coat reinforced with standard or armored glass fibre mesh and silicone or silicone-silicate binders as finishing coats. The influence of various renderings components was evaluated with respect to resistance to hard body impact and resistance to hail. The test results were discussed in the context of the possible impact level on ETICS in use.
