Die Erfindung bezieht sich auf ein Zwischenblech zur Verwendung als Zwischenlagen zwischen mehreren zu Holzspan- oder dergleichen -platten in jeweils einer Pressenetage zu verpressenden Holzspanoder dergleichen -kuchen.The invention relates to an intermediate sheet for use as intermediate layers between several to chipboard or the like -boards in each one press floor to be pressed woodchip or like cake.
Es ist bekannt, Holzspan- oder dergleichen -platten zur Erhöhung des Herstellungsausstoßes beim Pressen in Schichten anzuordnen, wobei zwischen den einzelnen Holzspanschichten Zwischenlagen in Form von Zwischenblechen vorgesehen sind.It is known to use wood chipboard or the like to increase the production output Arrange presses in layers, with intermediate layers in between the individual wood chip layers Form of intermediate sheets are provided.
Da man unter einem Druck bis zu 100 kg/cm2 und einer Temperatur zwischen 150 und 200° C zu arbeiten hat, ergibt sich die Verwendung von Blechen aus Metall oder Legierungen mit einem guten Kriechwiderstand bei Hitze.Since one has to work under a pressure of up to 100 kg / cm 2 and a temperature between 150 and 200 ° C., sheets made of metal or alloys with good creep resistance when exposed to heat are used.
Es hat sich jedoch herausgestellt, daß mehrere dieser für diese Eigenschaften bekannten Metalle oder Legierungen nicht befriedigten. Bei Verwendung von Stahlblechen korrodieren diese allmählich, es bildet sich Rost mit den Bindemitteln und der Feuchtigkeit, und schließlich verformen sich nach einer gewissen Zeit die Bleche. Aus reinem Aluminium oder aus einer Al-Mg-Legierung mit 3 bis 5% Magnesium oder einer Al-Si-Mg-Legierung hergestellte Bleche sind hinsichtlich Korrosion sehr widerstandsfähig, aber sie verformen sich allmählich unter der Wirkung von zunächst verschiedenen Ausdehnungen und dann des Kriechens.However, it has been found that several of these metals or known for these properties Alloys were unsatisfactory. When using steel sheets, they gradually corrode and form rust with the binders and the moisture, and eventually deform after a certain amount Time the sheets. Made of pure aluminum or an Al-Mg alloy with 3 to 5% magnesium sheets made of an Al-Si-Mg alloy are very resistant to corrosion, but they are gradually deformed under the action of initially different expansions and then of crawling.
Die Erfindung hat sich die Aufgabe gestellt, ein Zwischenblech der eingangs genannten Gattung zu schaffen, das nicht mit den erwähnten Nachteilen behaftet ist, sondern eine lange Nutzungsdauer bei guter Formfestigkeit und hohem Kriechwiderstand gewährleistet.The object of the invention is to provide an intermediate sheet of the type mentioned at the beginning create that does not have the disadvantages mentioned, but a long service life good dimensional stability and high creep resistance guaranteed.
Nach der Erfindung wird dies bei einem Zwischenblech zur Verwendung als Zwischenlagen zwischen mehreren zu Holzspan- oder dergleichen -platten in jeweils einer Pressenetage zu verpressenden Holzspan- oder dergleichen -kuchen dadurch erreicht, daß es aus einer Aluminiumlegierung mit Kupfer und einem oder mehreren der folgenden Bestandteile besteht: Silizium, Lithium, Magnesium, Kadmium, Mangan, Nickel und Titan.According to the invention, this is in an intermediate sheet for use as intermediate layers between several wood chips to be pressed into chipboard or the like in one press floor each or the like -cake achieved in that it is made of an aluminum alloy with copper and consists of one or more of the following components: silicon, lithium, magnesium, cadmium, Manganese, nickel and titanium.
Vorzugsweise beträgt der Kupferanteil in den Aluminiumlegierungen im allgemeinen zwischen 1 und 20°/o, und der Anteil der anderen Bestandteile außer dem Kupfer liegt im allgemeinen unter 3 %.The copper content in the aluminum alloys is preferably generally between 1 and 20%, and the proportion of the components other than copper is generally less than 3%.
Zur Veranschaulichung der Erfindung werden nachfolgend einige Legierungsbeispiele genannt.To illustrate the invention, some alloy examples are given below.

d) Legierung:d) Alloy:

Einige dieser Legierungen haben einen Kriechwiderstand für Temperaturen von deutlich über 200° C. Es wird also möglich, den Herstellungsrhythmus der Pressen durch Verminderung der Zeit für das Formen zu verbessern, da dieses bei einer Temperatur von über 200° C erfolgen kann.Some of these alloys have a creep resistance for temperatures well above 200 ° C. It is therefore possible to change the production rhythm of the presses by reducing the time for molding, as this can be done at a temperature of over 200 ° C.
