Effect of Production Factors on Formaldehyde Emission of MDFPs

Simulation of the common application environment of furniture were carried out, effects of different processing methods, storage time and airtight time were investigated. The results showed that the longer storage time or shorter airtight time was, the lower formaldehyde emission was. While the shedding of edge banding and metal connecting parts would increase the formaldehyde emission.

Study on the Solid Edge Banding Cracking of Panel Furniture

With the development of wood processing technology, panel furniture is getting more and more popular, where solid wood is often used for the edge banding to keep the natural wood grain, feel and colour. However, part of the panel furniture, especially that made in the south but sold to the north, has banding cracking issues due to various reasons. In this paper, on the base of comprehensive reference analysis and in-field exploration, the potential factors leading to banding cracking is studied; the influence of wood moisture content and adhesive on the cracking is specially analyzed; and the suggestions on the drying of the solid wood, glueing, manufacturing environment and process are presented. Thus, a new systematic concept to solve edge banding cracking is established, the study on which will be helpful to the development of panel furniture.

Edge Reinforcement of Honeycomb Sandwich Panels

Protection of the fragile honeycomb core material in hollow-core panels has long been a subject of interest for the manufacturers because it is necessary to seal the panel edges to prevent damage. Traditionally this has been accomplished by using edge banding, which has the added benefit of improving panel bending strength and stiffness. This study focuses on evaluating the effects of edge banding on the bending strength and stiffness properties of honeycomb core panels. The honeycomb panels were made with a combination of different face sheet materials (3-mm hardboard or 6-mm medium-density fiberboard [MDF]), rail types (particleboard or yellow poplar [Liriodendron tulipifera]), and rail widths (10 or 38 mm), and had edge-band materials fixed to their long edges using either direct coating, stabilizer edge, or surface folding techniques. Panels made with the 6-mm MDF face sheet and 38-mm poplar rails had the highest strength properties. To safely apply edge banding to honeycomb core panels, a solid edge reinforcement material is required to prevent the core material from being crushed during the process. The surface folding technique was the best method of edge banding and significantly enhanced the maximum bending moment of honeycomb core panels—more than twice that of panels without edge banding.

Evaluation the effects of edge banding type and thickness on the strength of corner joints in case-type furniture

Edge banding is used to cover the exposed sides of wood materials such as plywood, particleboard or medium-density fiberboard, giving the appearance of a solid (or more valuable) material. This study was carried out to determine the effects of the edge banding material, namely polyvinyl chloride (PVC), melamine and wood veneer, thickness of edge banding material (0.4, 1, and 2 mm), and wood composite panel type on the diagonal compression and tension strength properties of particleboard surfaced with synthetic resin sheet (LamPb) and MDF surfaced with synthetic resin sheet (LamMDF). The diagonal tension strength was greater than the diagonal compression strength of all L-type corner joints. Samples with edge banding gave higher diagonal tension and compression strength than control samples. LamMDF corner joints were stronger than LamPb corner joints. As for the type of edge banding, melamin type edge banding material gave more diagonal tension and compression strength than others. The lowest tension and compression strength was obtained in PVC edge banding material. There were significant differences in strength in terms of type of edge banding and wood composite panel material. A clear relationship between edge banding thickness and strength could not be determined. As case furniture constructions are under diagonal tension and compression forces, spline joint using 0.4 mm melamine edge banding can be recommended as the most robust corner joint type for case furniture produced from LamMDF panels.

Using lasers in edge banding

Lasers are increasingly used in industrial applications. In the furniture industry, lasers have not yet become an established tool, which is in contrast to the general trend in other industrial branches. The article will demonstrate the true potential of this technology for the edge banding process in furniture manufacturing.

The effects of edge banding thickness of uludag fir bonded with some adhesives on withdrawal strengths of beech dowel pins in composite materials

Composite materials and wooden dowels are being used increasingly in the construction of furniture frames and inner decoration. Yet there is little information available concerning the withdrawal strength of various fasteners, and, in particular, dowels in composite materials edged solid wood edge bandings. The aim of this study was to determine the withdrawal strengths of 6, 8, 10 mm diameter dowels produced from beech with respect to edge of a medium-density fiberboard (MDF) or particleboard (PB) edged with 5, 10 and 15 mm thickness of solid wood edge banding of uludag fir, bonded with different adhesives. According to TS 4539 standard, the effects of edge banding thickness, dimension of dowels, type of composite materials and type of adhesives used for edge banding on the withdrawal strength were determined. The highest (6.37 N/mm²) withdrawal strength was obtained in beech dowels with 8 mm diameter for MDF with 5 mm thickness of solid wood edge banding of uludag fir bonded with D-VTKA adhesive. According to results, if the hole wall and the surface of dowel are smooth then the adhesives give better mechanical adhesion with dowels and composite materials.

The effect of edge banding thickness of white oak bonded with different adhesives on withdrawal strengths of beech dowels in composite materials

Dowel joints are widely used in furniture frame construction as a load-bearing connection structure, as well as a simple locator for parts. Joints constructed with dowels were subjected to withdrawal, bending, shear, and tensile forces. The aim of this study was to determine the withdrawal strengths of 6, 8, 10 mm diameter beech dowels embedded into matching holes drilled into the edges of medium-density fiberboard (MDF) and particleboard (PB) with solid wood edge banding of white oak with 5, 10 and 15 mm thickness, bonded with hot-melt, poly(vinyl acetate) (PVAc) and Desmodur-VTKA (D-VTKA), a polyurethane-based one-component adhesive. The effects of edge banding thickness, dowel dimension, type of composite material and type of adhesive used for edge banding on the withdrawal strength were determined. According to the interaction results from the Duncan test the highest withdrawal strength (7.019 N/mm2) was obtained in beech dowels with 6 mm diameter for MDF with solid wood edge banding of white oak with 10 mm thickness bonded with the hot-melt adhesive. Should the dowels be subjected to withdrawal, it is advised that a beech dowel should be used for MDF with solid oak edge banding with 10 mm thickness bonded with a hot-melt adhesive in furniture production and decoration applications.

Kenaf nonwovens as substrates for laminations

Laminated products are used universally in the manufacture of furniture, kitchen cabinets, fixtures, wall-coverings, displays, and various other products. Laminates are usually made of two layers, the underlayer or substrate and a decorative upper layer, made of vinyl, polyester, melamine, etc., that is bonded to the substrate. These substrates can be made of many different types of natural or synthetic fibers. Kenaf's mechanical properties makes it an excellent fiber-source for nonwoven textile materials. Kenaf nonwoven substrates can be used in wall-coverings, upholstery covers, edge banding materials and other laminates. The purpose of this study is to show the feasibility of making nonwoven textiles with kenaf fibers that can be used in laminated products. Therefore, kenaf fibers were blended with polypropylene at a ratio of 80:20, and batts were prepared using a modified cotton card in regular widths. The batts were either calendered or needlepunched and cured in an oven to make the substrates. These substrates were then laminated with various kinds of overlays such as polyester wood grain, phenolic resin impregnated kraft paper, and decorative vinyl.
