New method for determination of mineral wool products macrostructure

This paper presents the research on the estimation of mineral wool macrostructure parameters. The orientation of fibres in the mineral wool structure can be described by the macrostructure parameter SL-C. It was determined that product with a homogeneous structure may be classified based on the numerical values of macrostructure parameters: the product with a quasi - horizontal orientation the value SL-C is ≤ 0.75 and if the va lue SL-C is ≥ 1.10 products are quasi - vertical orientation. Products with intermediate SL-C value (0.76 – 1.09) have a quasi - chaotic orientation. The developed method may be used to optimize pr o duction processes and/or improve the physical - mechanical prope rties of the mineral wool products
