Abstract:
The invention relates to a raw material charge for a melt for producing continuous material fibres, containing 30 % - 70 % basalt and/or diabase, 8 % - 40 % quartz components, in particular quartz sand, and 5 % - 30 % slag, in particular blast furnace slag. The invention also relates to the use thereof, to a method for the production of continuous mineral fibres from a melt, said melt being formed from raw material comprising 30 % - 70 % basalt and/or diabase, 8 % - 40 % quartz components, in particular quartz sand, and 5 % - 30 % slag, in particular blast furnace slag.
Abstract:
The invention relates to basalt fibres containing the elements Si, AI, Fe, Mn, Ti, Ca, Mg, K, Na and O. The Si-central atom is surrounded by four oxygen atoms, and the additional elements are also surrounded by oxygen atoms in different coordinations or are at least coupled to oxygen atoms and form other structural units. The pre-oriented and/or the oriented molecule structures, in particular domains, are present in an otherwise x-ray amorphous structure.

Abstract:
The invention relates to a method and device (10) for testing treatments (14) which introduce energy into objects (1), wherein the method comprises the following steps: bonding at least one chemical, optically luminescent compound (3) onto at least one indicator element (6) for testing the treatments (14), wherein at least one luminescence property of the chemical compound (3) can be changed; assigning at least one indicator element (6) to the object (1), wherein the indicator element (6) and the object (1) are simultaneously subjected to the same conditions of the energy-introducing treatment (14); changing the luminescence property of the chemical compound (3), wherein the level of the change to the luminescence property depends upon the energy-introducing treatment (14; irradiating (13) the chemical compound (3) with electromagnetic radiation directed onto the indicator (6) for excitation of the luminescence during the energy-introducing treatment or following the energy-introducing treatment (14) in order to demonstrate the instantaneous energy-introducing treatment (14) or the energy-introducing treatment (14) carried out; time-resolved and/or spectrally-resolved detection of electromagnetic radiation (12) emitted as a result of luminescence of the chemical compound of the indicator element (6) during the luminescence-emitting irradiation (13) or after the luminescence-emitting irradiation (13) is switched off; providing time-resolved and/or spectrally-resolved detection signals from a detector (5) to at least one evaluation unit (9) in which: - the detection signals (17) and reference signals (18) which are stored in a memory (16) and which consist of at least one previously determined reference value and/or at least one reference wavelength or of at least one reference wavelength spectrum are compared and - the energy-introducing treatment (14) carried out on the object (1) is demonstrably established; and displaying same in a display unit (15) after testing for the presence of at least one energy input (14) in the object (1) on the basis of the achieved changed luminescence property of the chemical compound (3).
