Abstract
Description
Holzspanplatten werden üblicherweise aus Sägespänen hergestellt, die unter Druck und Hitze mit Kunstharzbindemitteln verdichtet und zusammengepresst werden.Chipboard is usually made from sawdust, the under pressure and heat with synthetic resin binders be compressed and pressed together.
Bei sogenannten Flachpressplatten, erzeugt mit beheizten, hydraulischen Plattenpressen, liegen die Späne vorzugsweise parallel zur Plattenebene, bei Strangpressplatten, hergestellt beispielsweise nach den sogenannten Stopfverfahren als endloses Band in einem Presskanal, sind die Späne vorzugsweise senkrecht zur Plattenebene orientiert.With so-called flat pressed plates, produced with heated, hydraulic plate presses, the chips are preferably produced parallel to the plate level, in the case of extruded plates for example according to the so-called tamping process endless belt in a press channel, the chips are preferred oriented perpendicular to the plate plane.
Holzspanplatten werden zum Teil mit Folien beschichtet, furniert oder lackiert und im Möbelbau, für Wand und Deckenverkleidungen im Innenausbau, als Unterlage für Fussböden und als Konstruktionselemente im Holzbau verwendet.Particle boards are partially coated with foils, veneered or lacquered and in furniture making, for wall and ceiling cladding in the interior, as a base for floors and used as construction elements in timber construction.
Insbesondere im Möbelbau zeigen die bekannten Holzspanplatten aufgrund ihrer mangelnden Stabilität wesentliche Nachteile. So ist bekannt, dass sich Holzspanplatten bei Verwendung als Tablare für Regale und dergleichen sowie auch bei der Verwendung als Türelemente bei konstanter Druckbelastung bald einmal verziehen und durchbiegen. Dies hat zur Folge, dass die Möbel entsprechend mit Unterstützungs- und Verstrebungselementen und/oder die Platten selbst mit Verstärkungen ausgebildet werden müssen, will man langfristig ein Verziehen der Holzspanplatten verhindern, oder aber dass anstelle von Spanplatten verhältnismässig teure Massivholzplatten eingesetzt werden. The well-known particle boards are particularly popular in furniture making essential due to their lack of stability Disadvantage. So it is known that chipboard when in use as shelves for shelves and the like as well as at use as door elements with constant pressure load warp and bend soon. As a consequence, that the furniture accordingly with support and bracing elements and / or the panels themselves with reinforcements must be trained if you want to move into the long term prevent the chipboard, or that instead of Particle boards used relatively expensive solid wood panels become.
Der Erfindung liegt nun die Aufgabe zugrunde, eine Holzspanplatte vorzuschlagen, die insbesondere im Möbelbau einsetzbar ist und in dieser Verwendung die vorgenannten Nachteile nicht aufweist.The invention is based on the object, a chipboard propose that can be used in particular in furniture construction is and in this use the aforementioned disadvantages does not have.
Diese Aufgabe wird durch eine Holzspanplatte mit den Merkmalen des Anspruchs 1 gelöst, nämlich durch die Verwendung einer Spanplatte, deren Holzanteil mindestens zum Teil aus Hobelspänen besteht, im Möbelbau.This task is accomplished with a chipboard with the Features of claim 1 solved, namely by the use a chipboard, the wood content of which is at least partially consists of shavings in furniture.
Vorteilhafte Ausbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Advantageous developments of the invention are the subject of the dependent claims.
Die erfindungsgemässe für den Möbelbau vorgesehene Holzspanplatte hat eine Dicke von 0,5 cm bis 5 cm, beispielsweise 1 cm bis 3 cm. Sie besteht mindestens zum Teil aus Hobelspänen mit einer Spanlänge von beispielsweise 1 cm bis 20 cm, die unter Druck und Hitze mit Kunstharzbindemitteln verdichtet und zusammengepresst sind. Die Hobelspäne, welche in verschieden Formen und Längen in der erfindungsgemässen Holzspanplatte vorhanden sind, zeigen gesamthaft eine mittlere Spanlänge zwischen 3 cm und 12 cm, vorzugsweise zwischen 4 cm und 10 cm, auf.The chipboard provided according to the invention for furniture construction has a thickness of 0.5 cm to 5 cm, for example 1 cm to 3 cm. It consists at least in part of shavings with a chip length of, for example, 1 cm to 20 cm, which compresses under pressure and heat with synthetic resin binders and pressed together. The shavings, which come in different Shapes and lengths in the chipboard according to the invention are present, show a medium overall Chip length between 3 cm and 12 cm, preferably between 4 cm and 10 cm.
Zur Herstellung der Holzspanplatte wird entweder ein vollständig aus den vorstehend genannten Hobelspänen bestehendes Ausgangsmaterial oder aber ein Gemisch aus Säge- und Hobelspänen gemäss einem der bekannten Verfestigungs- und Pressverfahren zusammengepresst. Insbesondere im letzteren Fall beträgt der Anteil der Hobelspäne vorzugsweise mindestens 50 Gew.%, beispielsweise 60 Gew.% bis 80 Gew.%.To make the chipboard, either consisting entirely of the above-mentioned shavings Starting material or a mixture of saw and Wood chips according to one of the known consolidation and Pressing process pressed together. Especially in the latter In this case, the proportion of the shavings is preferably at least 50% by weight, for example 60% by weight to 80% by weight.
Die Holzspanplatten können entweder zur Plattenverstärkung oder aus ästhetischen Gründen an ihren Ober- und/oder Unterseite noch zusätzlich mit einer Kunststoffschicht oder Kunststoff-Folie beschichtet, furniert oder lackiert sein. Hierzu kann der Beschichtungswerkstoff wie folgt auf die allenfalls zu verstärkende Spanplatte aufgetragen werden. Zum einen kann der Werkstoff in Form von ebenen Platten und vorgeformten Rohlingen auf die Aussenseite der Holzspanplatte aufgeklebt werden. Andererseits kann der zur Verstärkung dienende Werkstoff auch als planarer Rohling zusammen mit dem zum Beispiel vollständig aus Hobelspänen bestimmten Ausgangsmaterial in der Pressmaschine verpresst werden.The chipboard can either be used to reinforce panels or for aesthetic reasons on their top and / or Bottom additionally with a plastic layer or Plastic film coated, veneered or lacquered. For this purpose, the coating material can be applied as follows chipboard to be reinforced if necessary. To the one can the material in the form of flat plates and preformed Blanks on the outside of the chipboard be stuck on. On the other hand, the one serving as reinforcement Material also as a planar blank together with the for example, starting material made entirely from wood shavings be pressed in the press machine.
Die Vorteile der Verwendung von mindestens zum Teil aus Hobelspänen gebildeten Holzspanplatten liegen auf der Hand. So lassen sich mit solchen Platten die eingangs genannten Nachteile von Spanplatten im Möbelbau vermeiden, was nicht zuletzt auch eine bedeutende Kosteneinsparung für den Kunden zur Folge hat. Die erfindungsgemässen Holzspanplatten haben die Festigkeit und Stabilität von vergleichbaren Massivholzplatten und genügen in ihrer Ausbildung und Komposition den Stabilitäts-Erfordernissen, welche für Möbelplatten der eingangs genannten Art nötig sind.The benefits of using at least part of it Wood chips made of wood shavings are obvious. The plates mentioned at the beginning can be used with such plates Avoid disadvantages of chipboard in furniture construction, which is not last but not least, significant cost savings for the customer has the consequence. The chipboard according to the invention have the strength and stability of comparable solid wood panels and are sufficient in their training and composition Stability requirements, which for furniture panels of the beginning mentioned type are necessary.
