Definitions
- the invention relates to a method for producing a mineral melt for the production of mineral fiber products for thermal and / or sound insulation and for fire protection, in particular made of rock wool, in which at least residues originating from production, correction substances for setting the required composition and viscosity of the melt crushed and pressed with a binder to form stones and the stones are fed to a melting unit.
- Stone wool insulation materials are used for heat, sound and / or fire protection. Stone wool products are also used for growing plants or for strengthening e.g. Coating materials and other products or also used as mineral fibers for filtration purposes. In the following, the rock wool products listed as examples are collectively referred to as mineral fiber products.
- glass wool is commonly distinguished from rock wool.
- Stone wool is mainly produced from mixtures of broken effusion stones such as basalt or diabase and small amounts of limestone, dolomite and magnesite as supplements and coarse slag. These supplements can be added to the batch on their own or in different mixtures.
- These mixtures of natural raw materials broken down to the required size are increasingly being replaced by artificially produced bodies of the appropriate size, shape and strength, which are composed of various raw and residual materials as well as suitable binders. These bodies are referred to below as shaped stones.
- the shaped stones can contain fine-grained, broken natural stones.
- Production-related residues are added as additional components, for example from the coarser constituents that inevitably arise during the manufacturing process, such as melting beads, the solidified melt that arises when the melting furnaces are regularly emptied, together with the partially melted rock remnants and parts of the furnace lining made of refractory building materials, as well as the insulation materials or substrates that occur when trimming an endlessly produced fiber web.
- Other production-related residues are leftovers, defective products or used insulation materials or substrates to be melted.
- the production-related residues are processed for the production of shaped blocks, i.e. crushed, ground and then mixed with correction substances.
- the required composition of the batch is achieved, which ensures an even and rapid melting in the Effect melting unit.
- the temperature and viscosity of the resulting melt are influenced to such an extent that the most efficient, evenly running defibration process is achieved.
- Correction materials are, for example, slags from the steel industry such as converter or ladle slags or melting chamber granules from coal-fired power plants.
- Substances containing aluminum in oxidic and / or metallic form are also considered to be essential correction substances here.
- Suitable carriers are raw bauxite or calcined bauxite, as well as alumina cement, which of course can also function as a binder. From DE-OS 101 02 615 A1 and WO 02/057194 A1 based thereon, the use in this regard of catalysts which are no longer usable from the petroleum industry is known.
- correction substances are ores, such as hematite (Fe 2 0 3 ) or magnetite (Fe 3 0 4 ).
- the granular and fibrous components, the internal residues and the correction substances are predominantly mixed with inorganic binders, usually with the addition of water, and then pressed into shaped bodies.
- Inorganic binders are generally understood to mean hydraulically setting cements such as CEM I Portland cements, but also all types of special cements, such as alumina cement.
- the proportions of the binders in the shaped blocks are approximately 9 to 15% by mass.
- the conveyance and loading - in general the shaped blocks should reach a minimum compressive strength of 3-5 MPa after e.g. 3 days - they are together with the other raw materials or alone, however always together with the necessary lumpy fuels, the melting unit, in which the melt required for fiber formation is produced, which is then fed to the defibration unit.
- the defibration unit generally consists of several rollers rotating at high rotational speeds and staggered one above the other.
- the processability of the mineral melt is strongly dependent on the viscosity and the temperature of the melt. Both parameters can be specifically influenced by the choice of raw materials.
- the chemical composition of the melt and thus the mineral fiber products made from it affect its biosolubility, i.e. the possible dwell time of the mineral fibers in the human organism.
- This biosolubility results to a decisive degree from the proportions of the oxides and compounds of silicon, aluminum, titanium, sodium, magnesium, potassium, calcium, iron and their relationships to one another.
- the contents of the oxides and compounds of boron and phosphorus are also important for the biological solubility.
- a typical composition of a mineral melt for the production of commercially available, bio-soluble rock wool essentially consists of the following:
- the invention is based on the task of developing a generic method for producing a mineral melt for the production of mineral fiber products in such a way that, on the one hand, the costs for the raw materials are reduced, but at the same time the properties of the mineral fiber products to be produced are not deteriorated and improved in particular with regard to their insulation properties and bio-solubility.
- the solution to this problem provides that constituents of the shaped stones, in particular the correction substances and / or batch constituents, are at least partially replaced by used granular residues from a surface treatment of components, in particular used abrasives.
- composition of these residues from the surface treatment of components varies depending on the source of the abrasive or type of component and the purpose of the application.
- blasting media Natural blasting media occur in nature. They are washed, dried and partially broken (sea sand or garnet sand).
- Agricultural abrasives are by-products of agricultural products. They include walnut shells, ground fruit kernels, ground chaff, ground rice bowls, etc. Factory-made by-products from ore refineries are blasting agents made from slag. They count as mineral abrasives, since they are made from brass abrasives, copper or lead slag etc.
- Non-metallic abrasives are factory-made from silicon carbide, aluminum oxide and glass. Glassy combustion residues (eg from power plants) also fall under this group c.
- Metallic abrasives are made from chilled cast iron, malleable cast iron, aluminum, brass or bronze. Wire grit also belongs to this category. e types of abrasive are acc. DIN 8201 ff. Structured as follows:
- the edges of the blasting media are rounded off or the grain size is reduced so much by breaking that the effectiveness of the blasting media decreases significantly, so that it has to be removed from the process and generally disposed of.
- the solution to this task essentially provides for the use of the abrasive III-a.
- the other abrasives from group III and partly from group I are also suitable, but are hardly available in terms of quantity due to existing recycling and recovery routes.
- Group II abrasives represent only a subordinate amount in terms of quantity.
- the high organic content has so far not yielded any discernible advantage according to the state-of-the-art production process for mineral fiber products.
- the blasting media from different origins have different compositions (all figures in% by mass). In part, this composition changes slightly due to admixtures of the blasted component, usually metals or inorganic substances such as Staining and varnish residues:
- the abrasive residues described above have chemical compositions that are particularly suitable for the correction of the mineral melt for the production of mineral fibers.
- the used abrasives can be used, for example, to control the viscosity of the mineral melt. This viscosity has a decisive influence on the product properties of the mineral wool.
- the high proportion of Al 2 0 3 contained in some cases enables the substitution of other aluminum oxide supports.
- the aluminum oxide itself favors the biosolubility of the mineral fibers.
- the method according to the invention also has the advantage that the abrasive residues which are otherwise to be disposed of in the landfill can now be recycled.
- this form of recycling also significantly reduces the burden on the environment.
- shaped blocks are pressed which consist of 38 to 64% by mass of production-related residues, 5 to 25% by mass of used abrasive (silicate), 0 to 11% by mass of converter slag and 0 to 14% by mass of ladle slag , 10-25 mass% Al 2 0 3 carriers, for example bauxite and 9-15 mass% cement.
- abrasive silicate
- 0 to 11% by mass of converter slag 0 to 14% by mass of ladle slag
- ladle slag 10-25 mass% Al 2 0 3 carriers, for example bauxite and 9-15 mass% cement.
- the correction substances Al 2 O 3 carrier and melting chamber granulate are replaced by used blasting media (aluminate / silicate):
