MINERAL WOOL PRODUCT
The invention relates to a mineral wool product comprising mineral fibers that is marked with an UV or IR active substance and can therefore be identified under exposure to suitable radiation.
1 . Mineral wool insulation product comprising at least one UV or IR active component.
2 . Mineral wool product according to claim 1 , whereby the UV or IR active component is distributed through the mineral wool product, particularly homogeneously through the mineral fibers.
3 . Mineral wool product according to claim 1 , whereby the UV or IR active component is arranged in at least one locally limited section.
4 . Mineral wool product according to claim 1 , whereby the UV or IR active component is arranged at least one section of a surface of the product.
5 . Mineral wool product according to claim 1 , whereby the UV or IR active component is arranged on at least one section of a surface of the product in the form of an identifier.
6 . Mineral wool product according to claim 1 , whereby the UV or IR active component is present with a carrier medium in a mixture.
7 . Mineral wool product according to claim 1 , whereby the UV or IR active component is present with a binding agent or a lubricant in a mixture.
8 . Mineral wool product in accordance with claim 1 , whereby the mineral wool product comprises at least one UV active component selected from the group consisting of: flavonic acid, 4,4′ Distyryl-biphenyls, stilbenes, pyrazolines, coumarin, dihydroquinolines, naphthalene acid imides, benzoaxazole, benzioxazole compounds, riboflavin, quinine, chlorogenic acid, quinoline yellow, and derivatives thereof.
9 . Mineral wool product in accordance with claim 1 , whereby the mineral wool product comprises at least one IR active component selected from the group consisting of doped strontium sulphide, doped zinc sulphide, yttrium compounds, ytterbium compounds and erbium compounds.
10 . Mineral wool product in accordance with claim 1 , whereby the amount of UV or IR active component in the mineral wool product is less than 1% by weight based on the total weight of the mineral wool product.
11 . Mineral wool product according to claim 1 , whereby the UV or IR active component is water soluble.
12 . Mineral wool product according to claim 1 , whereby the UV or IR active component is monochromatically fluorescent.
13 . Use of at least one UV or IR active component as a marker or identifier in a mineral wool insulation product.
14 . Use of at least one UV or IR active component in accordance with claim 13 , in which the component is distributed throughout the mineral wool product.
15 . Use of at least one UV or IR active component in accordance with claim 13 , in which the component is provided at an external surface of the mineral wool product.
