| 摘 要： | INTRODUCTIONGlulam (namely glued laminated lumber) is a kind ofproducts that are assembled by sawn lumbers or smallsquares laminated in grain directions and glued in thedirection of thickness, width and length with adhesives.Not only does glulam possess the same property asnatural wood does, but also can avoid some defects,such as warping, distortion, split, etc. As one kind ofthree main engineered wood products as laminatedveneer lumber (LVL) and I-beam, glulam is widely usedin construc…

| Abstract: | This paper selected lumbers of Manchurian ash (Fraxinus rnandshurica), Manchurian walnut(Juglans mandshurica) and Spruce (Picea jezoensis var.kornarovii) for manufacturing glulam with water-borne polymeric-isocyanate adhesive to determine process variables. The process variables that includespecific pressure, pressing time and adhesive application amount influencing the shear strength of the glulam,were investigated through the orthogonal test. The results indicated that optimum process variables forglulam manufacturing were as follows: Specific pressure of 1.5 MPa for Spruce and 2.0 MPa both forManchurian ash and Manchurian walnut, pressing time of 60 min and adhesive application amount of 250 g/m2. |
