Influence of the mineral wool production technological parameters and humidity attack on its fibre fragility

Abstract

The water vapour attack causes the mineral wool fibre fragility increase. The intensity of the mineral wool fibre fragility increase during water vapour attack is higher in the case of mineral wool having a lower modulus of acidity (Mi,). Increasing of the mineral wool fibre inhomogeneity highly influences fragility increase under the water vapour attack. From the analysis of the investigation results of mineral wool fibre fragility emerged the idea that the value of the fragility of the newly produced mineral wool fibre and the intensity increase of this value under water vapour attack are the most important mineral wool quality characteristics.
