METHOD FOR RECYCLING MINERAL WOOL, A METHOD FOR PRODUCTION OF ACOUSTICAL PANEL ELEMENTS AND SUCH AN ACOUSTICAL PANEL ELEMENT
An acoustical geopolymer panel element comprising a layer comprising a fibre component and a geopolymer binder made from a mixture comprising ground mineral wool, wherein the layer has a density in the range of 20 - 400 kg/m3, a porosity in the range of 0,75 - 0,99 and a thickness in the range of 5 - 75 mm. The ground mineral wool may be ground glass or stone wool and the fibre component may be a wood fibre component, a polymer fibre component and/or a mineral wool component. The panel may further comprise an additional layer comprising mineral wool. Further described is the provision of a geopolymer mixture upon recycling mineral wool which is ground to powder and mixed with an alkali activator component. The invention also relates to a method for producing acoustical geopolymer panel elements which comprises the step of grinding elements comprising mineral wool for provision of a powder component.
