Parameters and conditions which define the qualitative characteristics of mineral wool products

The paper highlights the influence of charge mixture, stock temperature, its acidity index, viscosity, surface tension, physical state of the melt, the diameter of the melt jet, the distance from the overflow launder to the centrifuge rolls, the minimum gap between the working face of centrifuge rolls, their mutual position, velocity of roll periphery, the temperature of their working faces, the use of special physical methods of the exposure to the melt, the diameter and the length of fibers, the quality, composition and extent of the binder, the degree of its curing, the methods of exposure to fibers at the mat formation and the bulk density of mineral wool products on their qualitative characteristics.
