Abstract
Publisher Summary Homogeneity of the primary layer in the mineral wool production process is required for high-quality products. Mineral wool distribution along the primary layer in the outlet section of the collection chamber is asymmetrical and non-homogeneous. Secondary effects, such as the local tearing and rolling of mineral wool layer, are stochastic in character and result in temporal and spatial perturbations of the velocity field in the collection chamber. Manufacturers of mineral wool are trying to improve the insulating properties of the product. Primary layer quality criteria are assessed on the basis of the homogeneity and isotropy of fiber distribution in the final product. The final product is a plate of mineral wool with different possible nominal thicknesses and fixed nominal density. Discrepancies between the local density of mineral wool and its nominal value present a major problem. The multi-regression model presents the dependence between the statistical estimator RMS of mineral wool fluctuation in the final product and statistical estimator of the visualized signal.
