Definitions
- the invention relates to a method for producing a particular one Insulation panels made of mineral fibers with essentially divisible fiber insulation web mineral fibers oriented at right angles to their large surfaces, in which the mineral fibers are withdrawn from a collecting chamber and placed on a Conveyor belt as a primary fleece with essentially parallel to the large surfaces aligned mineral fibers are stored.
- the invention further relates to a device for performing the method with a conveyor belt for conveying a primary fleece made of mineral fibers from a collection chamber to one Shuttle station.
- Mineral wool insulation materials consist of glassy solidified fibers, which are used to preserve the elastic, resilient properties, but also to be classified as non-combustible insulation materials, with only less than 8% by mass, with mineral wool insulation materials made of stone wool with approx. 2 to 4% by mass of binders, especially phenol-formaldehyde-urea resins. Inorganic binders such as organic silicic acid compounds that react via sol-gel processes are also used. Flexible, compressible mineral wool insulation materials made from glass wool have bulk densities of less than 30 kg / m 3 . Comparable mineral wool insulation materials made of rock wool, which contain not inconsiderable proportions of non-fibrous components, are manufactured with bulk densities between approx. 23 to 45 kg / m 3 .
- mineral wool insulation materials which can be subjected to mechanical loads are known, for example for insulating flat roof constructions, which have bulk densities of greater than 130 kg / m 3 . Insulation materials of this type can also be used as plaster base boards in composite thermal insulation systems.
- the mechanical and thermal protection properties of the mineral wool insulation materials include depending on the orientation of the individual fibers. Are the fibers across the large surfaces of the mineral wool insulation aligned, the insulation is compressible. At the same time the insulation material also has low transverse tensile strength and thermal conductivity across the fiber orientation. Mineral wool insulation materials with great strength values to manufacture, it is necessary to predominantly the individual fibers to be aligned at right angles to the large surfaces. This is usually a fiber mass flow with its fibers lying horizontally and inclined flat through a continuous horizontal compression in one area unfolded between 1 to 2.5 and 1 to 3 with vertical compression at the same time.
- the primary fleece points along the slideways reduced adhesion between the fibers or fiber layers. This Areas of reduced adhesion are preferred along the original surfaces the primary fleece arranged. These are fiber layers that subtracted from a collecting chamber in thin material and to larger ones Stacks are continuously placed on top of each other. During transport and that Laying the primary fleece layers on top of each other will result in the fibers near the surface Zones of the primary fleece reoriented.
- the primary fleece layers accumulate on these surfaces Low-fiber flakes and recycled fibers form a composite weaken the fibers in this area from the outset. These weak areas are particularly effective if the insulation materials are repeated or continuously exposed to hydromechanical loads during use are.
- the unfolding or folding of the fibers using the described method is in the Height limited, because with increasing thickness and increasing forces Forming mutual effects, such as parallel bearings to the large surfaces. Decreases with increasing material thickness also the uniformity of the structure.
- the method described above is improved by that the fiber mass flow is guided through a system of deflection rollers is, whereby the individual fibers are stored horizontally in the deflection areas become.
- This additional process step affects the transverse tensile strength of the primary fleece.
- the suspended primary fleece is called a secondary fleece referred to which to increase its transverse tensile strength is processed that in the area of the two large surfaces of the Secondary fleece of horizontally stored fibers after the binder has hardened be separated into an area in which almost exclusively there are fibers arranged at right angles to the large surfaces.
- Insulation materials with a low material thickness of, for example, 100 mm must be up to 20% of the original volume can be removed in this way to create a mineral wool insulation product to achieve that mostly perpendicular to the big ones Has surface-oriented single fibers.
- the endless fiber mass flow is before Hardening furnace cut into individual sections, which sections then around Rotated 90 °, compressed horizontally and compressed vertically by 20%. With this method too, the fibers are below the large surfaces predominantly stored horizontally, so that these areas can be reached optimal transverse tensile strength must be removed.
- Mineral wool insulation materials manufactured according to this process have a maximum Material thickness of approx. 220 mm. Since in all process variants Unfolding in the direction of production is the bending, tensile and shear strength across the direction of production many times higher than in production and Direction of folding. In order to achieve high transverse tensile strengths with possibly even reduced ones To be able to achieve raw densities, insulation boards are made from such produced mineral wool insulation materials parallel to the production and unfolding direction cut into slices according to the desired insulation thickness. This process is relatively complex since it is not based on the actual one Production line can take place, but mostly using large format Sheets as primary material on separate cutting and deflection systems must be carried out.
- Lamellar panels produced in this way which are often used as plaster base panels in thermal insulation composite systems or as a load-bearing insulation layer in sandwich constructions with sheet metal or lightweight wood wool panels as top layers, are used to achieve high shear and connection stiffness as well as high transverse tensile strength of particularly intensive folding Subjected to fiber layers.
- the bulk densities of such lamella plates are in a range between approximately 70 to 105 kg / m 3 .
- the invention has for its object to provide a generic method or a generic device for performing the method in such a way that fiber insulation webs with an intensive folding of the mineral fibers can be produced in a simple and inexpensive manner, the mechanical properties in the two main axes of the horizontal plane are the same or almost the same.
- the solution to this problem in a method according to the invention provides that the primary nonwoven is divided into at least two, preferably several, in particular the same partial webs by cuts made at right angles to the large surfaces, that the partial webs are then rotated by 90 ° about their longitudinal axis and that the partial webs are leveled and joined to form a secondary fleece.
- a conventional Primary fleece produced in this way in several on a conveyor belt side by side lying partial webs is divided, which partial webs subsequently by 90 ° their longitudinal axis are rotated, whereupon the partial webs become a secondary fleece be leveled up. It can be provided here that all the partial webs together to be leveled to a secondary fleece or that individual partial webs leveled and the leveled partial webs to a secondary fleece be put together.
- the partial webs of Primary fleece one above the other before rotating about its longitudinal axis relative to the conveying plane to be ordered.
- the partial webs are their rotation around their longitudinal axis and together a pendulum device fed, which pendulates the stack of partial webs to the primary fleece.
- the oscillation takes place in the horizontal direction in the conveying direction of the secondary fleece receiving conveyor belt.
- the partial webs and / or the secondary fleece are preferably during and / or compressed after swinging up.
- the compression takes place in two directions substantially perpendicular to each other.
- the secondary fleece or the partial webs are made by laterally arranged pressure bands compressed to the desired width.
- the compression is preferably carried out continuously to produce a uniformly compressed product.
- the secondary fleece is then fed to a hardening furnace to harden the binder.
- the cover layer can be from the secondary fleece either before or after the hardening furnace be separated.
- the mineral fibers are parallel to the large surfaces. If the top layer is separated after the hardening furnace, so this results in a marketable product with an extremely laminar structure, with a corresponding bulk density, for example for impact sound insulation can be used under floating screed.
- the cover layer is separated before the secondary fleece is fed to a hardening furnace.
- the cover layer has uncured binder, so that the top layer after separation still with regard to its material properties can be changed.
- the application-specific required density of the top layer by compression of the top layer should be set if the binder has not hardened.
- the cover layer only after the passage the secondary fleece is separated by the hardening furnace.
- the inventive method has the advantage that over several pendulums several layers of fleece are guided to each other, for example a fiber insulation web to produce, which is constructed like a sandwich.
- a fiber insulation web to produce which is constructed like a sandwich.
- the primary nonwoven with one or more nonwoven layers, in particular different properties is put together. It can therefore, for example Fleece layers with higher and / or lower bulk density or with a higher or lower degree of compression, the joining of the different layers of fleece in front of the hardening furnace takes place so that the connection between the fleece layers in particular through the not yet hardened binder.
- the primary fleece before or during the swinging up.
- the surfaces of the Partial webs are impregnated with binders before the partial webs are brought together become.
- a further development of the method according to the invention provides that between adjacent sub-webs reinforcing fabrics and / or nonwovens made of, for example Glass, carbon, metal, temperature-resistant plastic and / or Natural fibers are arranged.
- Such fabrics can be used as reinforcement Fiber insulation sheets serve and increase the resilience of this fiber insulation sheet manufactured insulation boards.
- the secondary fleece is preferably at right angles before and / or in the hardening furnace compresses its large surfaces. In this way, a fiber insulation web produced with defined dimensions, without the risk of bulging the fiber mass in the hardening furnace.
- Hot air is preferably both perpendicular to the large ones in the hardening furnace Surfaces, as well as passed through the long sides of the secondary fleece a higher efficiency of the hardening furnace and thus an improved hardening to achieve the binder.
- the secondary fleece is also up to After the binder has cured, it is clamped on all sides.
- the secondary fleece becomes parallel to it large surfaces cut into individual sections.
- This approach has the advantage that a downstream dryer for the fiber insulation web in compact design can be designed.
- the individual sections are stacked next to and / or one above the other and fed to the dryer.
- Of course can also pass through the fiber insulation web at this time cuts into individual panels perpendicular to their large surfaces cuboidal configuration can be divided.
- the above-mentioned object of the invention is used in a generic device for performing the above Process solved in that the conveyor belt has a cutting device with which the primary fleece in side by side on the conveyor belt lying partial webs is divisible and that the cutting device has a rotating device is connected with which the individual partial webs relative to their longitudinal axis can be rotated by 90 ° before entering the shuttle station to form a secondary fleece break in.
- the cutting device has one corresponding to the number n of the required partial webs Number of n-1 saws, especially as band or circular saws are trained.
- a shuttle station are preferably arranged in pairs or Roller tracks are provided for all partial tracks.
- the shuttle station as a pair of pressure tapes or roller conveyors for each form a partial web, so that the device according to the invention a the number of partial webs corresponding to the number of partial webs Has printing tapes or roller conveyors.
- the shuttle station has a hardening furnace with at least two Print tapes is connected on the large surfaces of the secondary fleece rest and through which a heated gas, in particular hot air becomes.
- the pressure bands on the long sides are adjustable relative to each other arranged in the hardening furnace so that they are attached to secondary webs of different widths can be adjusted or, if set appropriately, an intended one Transfer compression to the secondary fleece.
- the pressure tapes on the long sides of the secondary fleece are permeable to air formed and in particular have openings through which heated Gas, especially hot air, is conducible to additional thermal energy insert the secondary fleece to harden the binder.
- the impregnated with a binder in a collection chamber collected primary fleece depending on the width and the thickness in divided two or more partial webs.
- the partial webs are then overlapped and individually deflected by 90 ° around their longitudinal axis and thus guided on one side onto a collective conveyor belt.
- the one above the other arranged partial webs are then fed to a pendulum, which consists of two parallel conveyor belts, around a common oscillate vertical axis, so that the partial webs meandering together be placed on the collective conveyor belt.
- the compression can also be achieved by stroke-like movement of these construction elements be carried out.
- the direction of movement of the printing tapes or Pressure rolls are preferably carried out at right angles to the conveying direction of the secondary fleece. But there is also the possibility of compression under one execute any angle in the direction of the conveying direction.
- the opposite conveyor belts or transport rollers are adjustable relative to each other, a compression of the partial webs combined with an intensive unfolding or folding of the fibers.
- the compression and folding of the partial webs can be individual for the individual partial webs be made so that when merging the individual partial webs a sandwich element with sections of different characteristics can be manufactured. For example, it is used in the manufacture of wide fiber insulation webs sensible to densify the inner partial webs and to fold as the outer so as not to be undesirable due to excessive side forces different densification of the entire fiber mass or the fiber insulation web across the width.
- the conveyor belts or transport rollers can increase the large surfaces with trapezoidal surfaces, for example in the shape of sheep's feet, be trained.
- the large surfaces of the partial webs can also be used be impregnated with binders to the partial webs after merging adhere better to each other, taking the additional binder is finally cured in the downstream hardening furnace and becomes a contributes to further improved adhesion of the partial webs to one another.
- reinforcing elements have a particular effect on the transverse tensile strength of the insulation boards and are capable of the inevitable time-dependent, through hygrothermal and / or hydromechanical Strength-related losses in the strength of such insulation materials not only increase compensate, but also lead to more security in the use of such Insulation materials.
- the collective conveyor belt can be used to optimally control the compression and folding from several individual conveyor belts or from roller sets or combinations of both construction elements exist, with decreasing Operate speed and thus a compression of the secondary fleece effect in the direction of transport. Furthermore, in the direction of transport, i.e. across the width of the production line several narrow strips or Roll sets can be arranged distributed across the width of the production line different speeds are driven. This ensures that the compression and folding also in the central areas of the secondary fleece can be influenced.
- a lower conveyor belt supplemented by a mirror-image arranged upper pressure band, which on the fiber mass to be folded or compacted acts.
- This print tape has primarily the task of favoring the folding, being too large Compression in the horizontal direction should be excluded as far as possible.
- the folding effect in the direction of transport can be the lower and upper sub-bands with projections protruding from their surface be formed, which engage in the fiber mass, in particular the secondary fleece and move the fibers relative to each other.
- the secondary fleece can have a material thickness between 200 and 2000 mm with a bulk density of approx. 40 to 300 kg / m 3 .
- the secondary nonwoven has fibers in the area below its large surfaces at a certain depth which are not essentially perpendicular to the large surfaces. Since a fiber insulation web is to be produced which has mineral fibers oriented almost exclusively at right angles to the large surfaces, these areas are subsequently separated from the secondary fleece by horizontally guided cutting tools.
- the separated fibers can be fed to an internal recycling process in a known manner and melted again. However, there is also the possibility that the separated fiber layers are fed back to the primary nonwoven directly or to the fiber mass flow in the collecting chamber after appropriate loosening.
- the secondary fleece is held together mainly by the lateral pressure tapes is the possible reorientation of the mineral fibers due to its own weight low in the support area of the fiber web.
- An upper print band is created here only so much pressure that a bulging of the secondary fleece by the Pressure of the side profile strips is prevented.
- Such a hardening furnace usually consists of two stable ones arranged one above the other Pressure tapes through which hot air is drawn.
- the secondary fleece remains approx. 2 to 15 minutes, preferably less than 10 minutes in the curing oven so that relatively hot air with temperatures of approx. 250 to 320 ° C can be used in order to achieve sufficient hardening of the binder.
- relatively hot air with temperatures of approx. 250 to 320 ° C can be used in order to achieve sufficient hardening of the binder.

- the fiber mass After leaving the drying tunnel, the fiber mass is exposed to room air cooled down.
- the energy content of the exhaust air can heat the dryer air be used.
- the endless secondary fleece is now cut open horizontally or divided into individual sections, which then form insulation boards.
- the secondary fleece can be cured of the binder can be divided into sections in the hardening furnace. These block-like Sections are stacked next to and / or on top of each other. The through this procedure Any energy losses that have occurred must be replaced by a corresponding Increasing the temperature, but especially due to a longer residence time in the dryer can be compensated.
- the secondary fleece conventionally cooled down by room air after the binder has hardened and horizontally in insulation boards with the desired dimensions and split vertically.
