Definitions
- the present invention relates to a plate made of a cellulosic material, with a content of cellulose-containing chips and with a proportion of binders, wherein at least within a plate layer micro-chip material is provided.
- Such a plate is for example from the DE 199 56 765 A1 known.
- Table 1 shows the diameters of the chips, the values of the table being understood to mean that, for example, for covering layer material, 95.8 mass% of the material to be screened passes through a sieve with a mesh size of 2.0 mm or 8.4 mass% through the screen mesh area from 1.4 to 2.0 mm.
- diameter is to be understood in the indication of a sieve fraction that the diameter in each case indicates the smallest diameter in a cross section in any direction of the particle or chip. Because in a screening, the particles to be sieved are moved so that too elongated particles are erected and come along the longitudinal extent through the sieve.
- the shavings are mixed separately into cover layers and middle layer in mixers with binder, hardener, wax emulsion and optionally additives and fed to the spreading machine, which forms a multi-layered chip cake mirroring the center of the board.
- the chip cake consisting of lower cover layer, a middle layer and an upper cover layer (three-layer or multilayer boards). But a multi-layered structure can also be completely missing, then one speaks of single-layer plates.
- a stable chipboard is pressed under the action of pressure and temperature, by curing the binder, which can meet the requirements of the European standard EN 312-3, shown in Table 2.
- the production of fiberboards by the dry process is known.
- the wood particles so-called wood chips, are softened by the action of pressure and temperature in a saturated steam atmosphere and then separated in a refiner into fine particles, the fibers. This process is also called defibration.
- MDF fibers are prone to clumping or felting, screening with screening machines such as chips is not possible to determine the size of the fibers. Therefore, the diameters of MDF fibers were determined by means of a laser particle counter.
- the sample material was homogeneously mixed with water to form an approximately 2% dispersion and fed to the PQM 1000 measuring device.
- the measured quantities were the number of fibers, with a certain length and a certain diameter, from which the mass fractions could then be calculated as a function of the fiber diameter. The results are shown in Table 3.
- the fibers leave the refiner together with water and steam via a pressure pipeline, the so-called blowpipe - also called blow-line.
- blowpipe - also called blow-line.
- this tube there are several leads for supplying binder, hardener, emulsion and other additives.
- the fiber-binder mixture thus obtained is transferred to the dryer - usually a tubular electric dryer in which the fibers are dried by the action of convective heat to a final moisture content of 8 to 15%.
- the result is binder-provided wood fibers from which a fiber cake is subsequently formed.
- a stable plate medium-density fiberboard MDF or high-density fiberboard HDF
- the panels comply with the requirements of European standard EN 622, Part 5, which defines the properties of MDF and whose values are shown in Table 4.
- a fiberboard in contrast to a chipboard, is distinguished by a very homogeneous density distribution over the plate thickness and over a very homogeneous surface. If the direct coating of chipboard makes high demands on the preparation of particle board surface quality, such as. can be achieved by trowelling, so an MDF board can be painted with conventional painting techniques without pretreatment as a chipboard. The reason for this is on the one hand the high isotropy of the MDF surface, which is ensured by the fineness and / or fiberiness of the wood, and on the other hand by the homogeneous suction behavior of the surface.
- fiberboard Another disadvantage in the production of fiberboard is that the fibers are not pourable Good and thus are expensive to handle.
- the conventional mixers used for particle board production can not be used for gluing the fibers.
- the fibers are very flexible due to their elongated rod-like shape with small thickness and have the so-called Curl bin. As a result, juxtaposed fibers entangle and matt easily, which makes pouring or sieving impossible for fractionation.
- a disadvantage of the fiberboard is that because of the high process temperatures, the color of the fibers and thus of the finished fiberboard is dark.
- the dark color makes a color coating difficult, for example by painting, when a light color, for example white, is to be achieved as the surface color.
- a molded wood material element comprising wood particles and a binder is known.
- the WO 92/06832 discloses a wood flour mixture suitable for the production of wood products.
- the US 2003/0001305 A1 shows a wood-like material plate, which is made of a mixture comprising binder 1 and lignocellulose particles.
- the US 5,277,024 discloses a low density material having a vegetable filling material.
- the EP 1 190 825 A2 a three-dimensionally shaped semi-finished or finished part, wherein the semi-finished or finished part of a mixture of wood and / or Wood fiber material and / or plant fiber particles and a liquid, heat-reactive binder.
- a plate made of a cellulosic material with a content of cellulose-containing chips and a proportion of binders known, at least within a plate layer microspan material is provided.
- the present invention is therefore based on the technical problem of specifying a chipboard, wherein the chipboard has properties of an MDF board without using the expensive MDF manufacturing process.
- the plate according to the invention consists of a cellulosic material with a proportion of cellulosic chips and a proportion of binders.
- Microplated material is provided within at least one plate layer, the chips having a proportion of micro-chips with a diameter of less than 1.0 mm, which is at least 75%, in particular at least 80% and preferably at least 90% of the chips.
- a further preferred embodiment of the invention even includes a proportion of greater than 95% chips with a diameter of less than 1.0 mm. It is also possible to produce a plate containing over 98% of micro-chips smaller than 1 mm in diameter.
- the plate according to the invention thus differs from the prior art, which is larger in the at least one layer, the proportion of micro-chips than conventional chipboard. It generally applies that the properties of the chipboard are better, the greater the proportion of chips under a diameter of less than 1 mm.
- the chips have a proportion of micro-chips with a diameter of less than 0.6 mm, which is at least 50%, in particular at least 65% and preferably at least 80% or even at least 85% of the chips.
- the proportion of small chips, so the micro-chips compared to the prior art is so high that the properties of such micro-chipboard are similar to the properties of MDF boards.
- the properties of the micro-chipboard are the better, the greater the proportion of smaller micro-chips.
- the plate may preferably be made entirely of the microspot mat material so as to give a homogeneous distribution of the micropipes within the plate.
- the plate has a middle layer, which consists of a conventional chip material, while the two outer layers consist of the micro-chip material. This ensures that the cheaper material of the chipboard is used in the middle, while the more expensive material of the micro-chips is used at the bottom and the top, in particular to be able to exploit the improved surface properties can.
- the inventive method is then designed accordingly, wherein only a part of the plate is made from the micro-chip cake.
- micro-chip material wood parts are machined analogously to chipboard production and dried to a residual moisture content of 2-5%, in particular 4-4.5%. Subsequently, the dry fiber is carried out in a fiber mill, which is for example by means of special V-groove strips and baskets in a position to produce fibers from the chips.
- the particles produced in the dry fiber are called micro-chips, which can also be derived from the properties of the micro-chips described below.
- a first distinguishing feature compared to fibers is that the micro-chips represent a pourable and pourable good. In contrast to the fibers for a production of a fiberboard so the micro-chips can be fractionated by a sieving.
- microspheric mixture obtained in this way has the following exemplary microspan size distribution which has been obtained by sieve analysis with sieves of corresponding mesh size.
- Table 5 shows the measurement results for the diameter of the micro-chips over several samples. The result is a diameter distribution which is close to the diameter distribution for fibers shown in Table 3. Further measurement results are explained in more detail in the examples discussed below.
- micro-chips are subsequently glued, and due to the nature of the micro-chips, conventional mixers used in the chipboard industry can be used.
- conventional mixers used in the chipboard industry can be used.
- fiber plate technology low-line gluing
- no damage to the binder occurs, which is reflected in a lower binder requirement.
- a proportion of binder based on the dry weight of the microprecipitants, of at least 12%, preferably 15-25%, is emphasized.
- the value of the binder content varies depending on the dust content of the chips, which occurs increasingly in the production of micro chips.
- micro chip cake is done in analogy to chipboard production. Again, no special devices are needed and it can be used on spreaders of the prior art.
- one-floor presses, multi-daylight presses, continuous presses such as conti-roll systems or calendering machines can be used.
- Another advantage of the method according to the invention compared to the MDF technology is that a grinding of the micro-chipboard is possible immediately after pressing. After hot pressing, MDF boards are stored for 2 to 5 days in the maturing warehouse before they can be sanded and subsequently processed. This circumstance is detrimental to the production logistics as well as to the manufacturing costs due to the necessity corresponding storage capacities and through the longer capital tie-up in the maturing warehouse.
- the mechanical technological properties of the micro-chipboard according to the invention correspond to the requirements for MDF boards by the dry process, as shown in Table 4 of EN 622, Part 5 above.
- sheets from 1.0 mm (for example calender presses) to more than 40 mm thick (platen press or conti-roll press) can be produced.
- the homogenous density distribution over the slab thickness, comparable with an MDF slab offers advantages in edge processing.
- Particle boards with a marked density minimum in the center of the board and the coarse chip structure of the middle layer chips on the other hand do not provide adequate conditions, for example, for direct paintability of the board edges.
- Chips from the production of thin chipboard by the calender process are mikrozerspant after drying the same by means of a fiber mill.
- the mill is characterized by special V-slot bar fittings that leave a narrow gap between stator and rotor of the mill. This can affect the Mikrospangeometrie.
- the microsphering mixture thus obtained shows the sieve fractionation shown in Table 6.
- the microsphering mix is mixed with 12% (solids to dry weight micro-chips) of a conventional urea-formaldehyde binder. Furthermore, 0.8 percent by weight of hardener based on solid binder based on ammonium sulfate and about 1.2% paraffin emulsion (solid wax based on dry weight micro-chips) are added in the form of a 60% emulsion.
- the mixture of the individual components with the micro-chips is carried out in a conventional continuous mixer, as it is used for the production of chipboard.
- micro-chip mat is formed using a spreader with wind and throw separation.
- the microspheric cake thus obtained is then pressed in a calender press under the action of pressure and temperature to form a stable plate having the mechanical technological properties shown in Table 7.
- the diameters are shown in cumulative distributions.
- the shavings of the conventional chipboard that are shifted to larger diameters, the values for the middle layer and the outer layer are shown.
- the curves for the micro-chips and the MDF fibers are very close to each other.
- a chipboard of the invention can be easily distinguished from a conventional chipboard by analyzing the size distribution of the chips.
- the micro-chips and the fiber can nevertheless be very well distinguished from each other. Because the fibers have, in contrast to the micro-chips on a much longer form, while the micro-chips have a more cubic or almost cubic shape. Cubic shape means that the dimensions of the micro-chips in length, width and thickness are substantially similar. Incidentally, in contrast to the fiber, the cubic shape makes it possible for the micro-chips to be a free-flowing and pourable material.
- the following test can be performed become.
- Material of the plate to be examined is treated in an acid bath in order to dissolve the aminoplast resin acting as a binder. Thereafter, the detached material is dried and mechanically sieved. If the material can be sieved, ie if it is sieve-capable, it results from the fact that the plate consists at least partially of micro-chips. If, on the other hand, a coherent, possibly tangling, mass is formed, then it can be assumed that it was a fiberboard.
- An essential criterion for the good paintability of the chipboard according to the invention is the limited absorbency of the surface. This is essentially determined by the small size of the chips, by the binder content and the calendar process additionally by the location of the heating drum. The lower the absorbency, the better the paintability.
- the absorbency can be quantified by means of the toluene test specified in EN 382-1: 1990 10 01 (Fibreboard, Determination of surface absorption, toluene test). It is applied a defined amount of toluene on the arranged at a certain angle to the horizontal specimens and the distance which the resulting droplets travels until it is completely absorbed by the substrate, then determined as a measure of the absorbency.
- the chipboard according to the invention therefore has a significantly lower absorbency than a conventional chipboard.
- the chipboard according to the invention can therefore be painted better than a conventional chipboard.
