Abstract

In an effort to establish a reference value for optimal surface roughness for high quality finish on Rubberwood (Hevea brasiliensis), a series of experiments were carried out using samples sanded with different grit sizes and applied with a clear lacquer. The results show that the surface roughness produced by the grit size 240 provided the highest surface finish quality, both in terms of coating film adhesion and sheen. This finding will have far reaching implications on Rubberwood furniture manufacturing practices as it enables the manufacturers to adopt a standard for surface roughness to ensure the highest quality finish.

Optimale Oberflächenrauhigkeit zur Erzeugung hochwertiger Oberflächen bei Gummibaumholz (Hevea Brasiliensis)

Zusammenfassung

Um eine Bezugsgrösse für die optimale Oberflächenrauhigkeit von Gummibaumholz (Hevea brasiliensis) zur Erzeugung hochwertiger Oberflächen festlegen zu können, wurden Versuche durchgeführt. Dabei wurden die Proben unter Verwendung verschiedener Körnungen geschliffen und mit Klarlack lackiert. Die Ergebnisse zeigten, dass die mit einer Körnung von 240 erlangte Oberflächenrauhigkeit bezüglich Farbschichthaftung und Glanz die beste Oberfläche lieferte. Diese Ergebnisse sind für die Gummibaumholz verarbeitende Möbelindustrie von grosser praktischer Bedeutung, weil sie die Standardisierung von Oberflächenrauhigkeit zur Erzeugung hochwertiger Oberflächen liefern können.
