Description
Kunstharzschnitzelpreßmasse Kunstharzpreßmassen, die als. Füllstoff Schnitzel aus Textilgewebe oder Zellstoff, z. B. Papier enthalten, .sind allgemein bekannt. Sie kommen als typisierte T2- und Z 2-Preamassen in den Handel. Die daraus hergestellten. Preßkörper zeichnen. sich durch hohe Schlagbiegefestigkeit und Kerbzähigkeit aus.Synthetic resin chip molding compound Synthetic resin molding compound, which as. filler Schnitzel made of textile fabric or cellulose, e.g. B. contain paper, are general known. They come on the market as typed T2 and Z 2 pre-masses. The one from it manufactured. Draw the pressed body. high impact resistance and notch toughness the end.
Es wurde nun gefunden, daß man in solchen Schnitzelpreßmassen die Textil- oder Zellstoffschnitzel durch entsprechende Holzschnitzel ersetzen kann, die höchstens i mm stank und parallel zur Faser geschnitten sind. Solche Holzschnitzel stehen in den Furnierabfällen, deren, nutzbringende Verwertung sehr erwünscht ist, in genügender Menge zur Verfügung und verleihen den. Preßmassen preßtechnisch gleiche Eigenschaften, wie sie die T2-Preßmasse besitzt. Auch. die Festigkeit der Preßkörper steht der aus T2-Preßmasse hergestelltem nicht nach. Ferner ergibt sich als bedeutender Vorteil, daß die Furnierschnitzelpreßmasse mit einem wesentlich geringeren Harzgehalt hergestellt wird. Der Harzanteil beträgt etwa 25 bis 3o0/0, während der bei den Celluloseschnitzel-(Z 2-) Preßmassen 40 bis 450/0 und der bei den Textilschnitzel-(T2-)Preßm.assen 45 bis 5a°10 beträgt. Die hierbei erzielte Harzersparnis ist also sehr bedeutend.It has now been found that in such pulp molding compounds the Can replace textile or cellulose chips with corresponding wood chips, which stank at most i mm and are cut parallel to the fiber. Such wood chips are in the veneer waste, the beneficial recycling of which is very desirable, available in sufficient quantities and lend the. Molding compounds are the same in terms of molding technology Properties like those of the T2 molding compound. Even. the strength of the compacts is not inferior to that made from T2 molding compound. It also turns out to be more significant Advantage that the veneer chip molding compound with a significantly lower resin content will be produced. The resin content is about 25 to 3o0 / 0, while the Cellulose chips (Z 2-) molding compounds 40 to 450/0 and the Textile chip (T2) molding compounds 45 to 5a ° 10. The resin savings achieved in this way are therefore very significant.
Di.eHerstellung derMasse erfolgt in- für Schnitzelpreßm.assen bekannter Weise durch Tränkung der Holzschnitzel mit Lösungen von, Kunstharz und Trocknen der Schnitzel. Den Preßmas.sen können noch lose Faserstoffe zugesetzt werden. Je nach Form und Abmessung der zu pressenden Teile und der sich hieraus ergebenden preßtecbnischen Bedingungen der zu pressenden Teile wird die entsprechende Schnitzelgröße gewählt. Die Breite kann hierbei 2 mm und mehr betragen, während die Länge der Schnitzel meistens ein Mehrfaches. der _ Breite beträgt.The production of the mass is better known for Schnitzelpreßm.assen Way by soaking the wood chips with solutions of synthetic resin and drying the schnitzel. Loose fibers can still be added to the press mats. Ever according to the shape and dimensions of the parts to be pressed and the resulting parts Pressing technical conditions of the parts to be pressed is the corresponding chip size chosen. The width can be 2 mm and more, while the length of the schnitzel mostly a multiple. which is _ width.
Die beanspruchte Preßmasse unterscheidet s4ch deutlich von bekannten. Preßmassen, die als Füllstoff Späne oder Schnitzel aus Holz (shavings of wood) enthalten, 'worunter man ohne Zweifel schmale, langgestreckte, in; Faserrichtung geschnitten-, Holzteilchen zu verstehen hat. Derartige Preßmassen lassen sich jedoch schwierig verpressen, und ihre Preß.körper besitzen nicht die Festigkeit der erftndungs.gemäß hergestellten.The molding compound claimed differs clearly from known ones. Molding compounds which contain wood chips or chips as filler (shavings of wood), 'which undoubtedly mean narrow, elongated, in; Grain direction cut, Has to understand wood particles. Such molding compounds can, however, be difficult press, and their Preß.körper do not have the strength of the inventions manufactured.
