Definitions
- the invention relates to processes for the production of a mineral wool product, in which a raw nonwoven provided with an uncured binder mineral wool on a conveyor for molding the product and for curing of the
- Binder is passed into a curing oven, which is designed in the manner of a tunnel oven and has an upper belt and a lower belt.
- the invention further relates to a device according to the preamble of claim 9 and the use of this device according to claims 17 and 18 and a mineral wool product according to claim 19.
- a raw fleece is first produced. This contains mineral wool fibers, which are produced in a defibration station, then wetted with an uncured binder and then deposited on a conveyor.
- the raw nonwoven fabric thus formed is typically carried away by the conveyor continuously from the area of the fiberizing station and is generally subjected to finishing steps such as, for example, thickness compression, longitudinal upsetting or the like.
- this raw nonwoven is passed into a curing oven, in which the binder usually cures by heat and / or radiation and thus results in a product with a predetermined geometry, which is still available as a continuous web.
- hardening furnace with an upper belt and a lower belt are often used for the hardening step, between which the raw fleece is present and by means of which the raw fleece is moved through the hardening furnace.
- Such hardening furnaces are also referred to as tunnel ovens.
- a heated hardening gas such as e.g. Provided air with overpressure, wherein on the lower belt, a negative pressure is applied in such a way that the hardening gas, starting from the upper belt flows through the raw fleece and finally the lower belt and is sucked out there.
- This process can also be carried out in the opposite direction.
- a tunnel kiln can also be subdivided in sections into several curing areas, as a result of which different temperature zones can be set. The flow ensures that not only the binder in the near-surface areas of the raw nonwoven cures, but a complete through hardening of the web succeeds.
- the hardening gas to be effective, it must not only penetrate the mineral wool but also be able to pass through corresponding openings in the upper belt and in the lower belt.
- the upper and the lower band must have a sufficient perforation, so that the desired fürströmungshack and thus achieves a practical curing speed become. This procedure for curing a binder in a mineral wool fleece has proven very successful in practice.
- the invention is therefore based on the object to further develop a method and apparatus for producing a mineral wool product of the generic type such that the Nachbearbeitungsaufwand can be reduced to the resulting from the curing oven mineral wool products.
- Claim 1 solved. This is characterized in particular by the fact that between the raw fleece and the upper belt and / or the lower belt, a diffusion-open release belt is arranged.
- the invention is thus based on the finding that it is possible despite the non sticky by the uncured binder surface of the nonwoven fabric and the required maintenance of skillsströmungsdite of Rohvlieses by the hardening medium, a separating element between the surface of the nonwoven fabric and the upper belt and / or To arrange sub-band and so prevent the penetration of mineral wool sections in the flow openings therein.
- the mineral wool products produced by the method according to the invention can thus be used on the visible surface without a post-processing step, so that in particular the costly grinding step on the product surface can be dispensed with.
- the production cost of such mineral wool products reduced significantly, which speeds up production, reduces the equipment as well as human resources and thus significantly reduces costs.
- the grinding step still required, but the advantages listed can be at least partially realized.
- the method according to the invention makes it possible to reduce the hitherto often multi-stage to a single-stage grinding step.
- the separating tape according to the invention is designed to be open to diffusion, so that it allows a reliable flow through the hardening medium and thus does not significantly hinder the hardening step.
- the inventive method thus continues to achieve a reliable through hardening of the mineral wool product to be produced.
- Another advantage is that the method according to the invention can easily be adapted to these variants by a slight modification of conventional production lines. is feasible. The cost of retrofitting conventional production equipment is therefore low.
- the separating belt can be fed to a large surface of the raw non-woven in the conveying direction before the curing oven and led away in the conveying direction after the curing oven from the cured web.
- This can be achieved with simple means a provision as well as a removal of the separating tape directly in the desired work area. In particular, this can be retrofitted with little effort a conventional production line.
- the separating belt it is possible for the separating belt to be pulled off a ready position roller in front of the hardening furnace and rolled up onto a collecting roller after the hardening furnace.
- the separating tape can be applied in the manner of a conventional lamination with simple means on the upper or lower surface of the raw nonwoven and then lift off again with little effort.
- This procedure has the advantage that it can be carried out with very little effort on conventional lending lines and does not adversely affect further production steps.
- the separating belt can be easily disposed of after a single use or as far as possible after a desired number of applications, without the continuous manufacturing process would be affected thereby.
- the separating belt can be provided as an endless belt, which is cleaned off, for example, continuously by binder residues etc. adhering thereto. Even such an endless belt can be excellently integrated into the continuous production process in the production of mineral wool products. An adaptation of conventional processes is possible with little effort.
- a separating band it is also possible for a separating band to cover the upper band and / or the lower band and to circulate with it. This has the advantage that changes to the production plants arise only within the curing oven and here in the range of the upper band and the lower band.
- the separating belt can be arranged, for example, in the manner of the stocking over the upper belt or the lower belt and can be continuously cleaned by suitable means. The space required for this procedure is particularly low.
- the separating tape can be formed as a glass filament fabric, for which the terms glass fiber fabric or glass fabric are used, which has proven in practical experiments to be particularly suitable for this purpose.
- Glass filament fabric has good structural integrity, although it has only a very small thickness, so that a very vapor-permeable release tape can be achieved.
- the flow resistance in the curing oven is therefore only slightly influenced by such a glass filament fabric.
- such a glass filament fabric has an open-pore shape with irregular, relatively small pores, so that there are no flow openings of the size that mineral wool material from the raw fleece would enter into this relevant extent.
- such glass filament fabrics have a sufficient intrinsic stability that they can reliably bridge the flow openings in the upper band or in the lower band against the compression pressure within the curing oven and thus reliably counteract the formation of elevations on the product surface of the mineral wool fleece. Furthermore, this inherent stability allows a reliable lifting of the release tape from the cured web without damaging the nonwoven structure of both the glass filament and the cured web.
- the separating tape made of polytetrafluoroethylene
- PTFE polytyrene resin
- This plastic is characterized by excellent material properties, in particular with regard to its heat resistance and its adhesion protection.
- hardened binder does not adhere to a relevant extent on a release tape made of PTFE, so that it comes when lifting from the product surface to no destruction of these in the process flow.
- PTFE can be provided in very thin layers and with suitable perforations, so that the flow resistance with respect to the flow through the raw nonwoven by the hardening medium hardly develops relevance.
- a film-like separating belt further has a very good mechanical strength.
- the separating belt in particular as a stainless steel mesh, which is particularly advantageous in terms of robustness and longevity of the separating strip.
- an apparatus for producing a mineral wool product comprising a conveyor for directing a raw web of uncured binder mineral wool to form the product and cure the binder into a hardening furnace, which is of the type known in the art Tunnel furnace is formed and has a top band and a lower band.
- the device according to the invention is distinguished by the fact that a diffusion-open separating belt is arranged between the raw fleece and the upper belt and / or the lower belt.
- the device according to the invention can be used particularly advantageously in the production of sound insulation panels, since these typically have a relatively large density in order to support the soundproofing effect. Accordingly, the degree of compression of the raw nonwoven fabric in the curing oven is comparatively high and thus in conventional devices the degree of mineral wool entry into the throughflow openings in the upper band or in the lower band is particularly pronounced.
- the invention further provides a mineral wool product, in particular a sound insulation panel or facade insulation panel, from bonded mineral wool, which is preferably produced by a method according to the invention or a device according to the invention.
- This mineral wool product is characterized in that at least one large area thereof is flat and has no elevations, which are formed by openings in the upper band and / or in the lower band of a curing oven.

- a separating belt 5 is provided, which is drawn off from a supply roller 6 arranged in the conveying direction in front of the hardening furnace 2 and introduced into the region between the raw fleece 3 and the upper belt 21.
- the separating belt 5 is lifted off from the now formed mineral wool nonwoven 4, wherein the separating belt 5 is rolled up onto a collecting roller 7.
- the collecting roller 7 As soon as the separating belt 5 has been completely removed from the supply roller 6, it is either replaced by the collecting roller 7 or another supply roller with a separating belt 5 which has not yet been used or which has already been used.
- a separating belt 5 ' is formed as an endless belt and is guided around by deflecting rollers 8 around the upper portion of the curing oven 2, that within the curing oven 2 between the surface of the green fabric. 3 and the upper belt 21 of the curing oven 2 comes to rest.
- a separating belt 5 "completely covers the upper belt 21 of the hardening furnace 2 and circulates therewith, while the separating belt 5" is stretched over the upper belt 21 like a stocking.
- FIG. 4 shows a cross section through the conventional mineral wool product 9, on which significant elevations 91 are visible on the sides of both large areas, which are also referred to as flight prints.
- FIGS. 1 to 3 shows the mineral wool product 9 'produced by a device 1 according to one of the FIGS. 1 to 3, in which there are no elevations 91 on the upper side, since the separating strip 5 or 5' or 5 "was arranged there On the underside, to which no separating belt was used in the illustrated embodiments, there are also elevations 91.
