Abstract
Effects of nano-wollastonite (NW) on physical and mechanical properties of medium density fiberboard (MDF) were studied. NW was applied at 5, 10, 15, and 20 g/kg dry weight basis of wood fibers; the results were then compared with control specimens. Two application methods of NW were used: surface and internal applications. Density was kept constant at 0,67 g/cm3 for all treatments and tests were carried out in accordance with ASTM D-1037. Addition of NW contributed in improving the physical and mechanical properties of the panels, both when applied internally or as surface treatment. It was concluded that NW contents of 10% and 15% were the optimal levels for industrial purposes for internal and surface applications, respectively.
Highlights
Composite-boards have the advantages of a homogeneous structure and the use of residual raw materials
Visual observation showed there was no difference between the control panels and panels with NW contents of 5, 10, and 15%
Surface application of NW resulted in the same roughness on the surface of panels as a result of the water-based paint that was sprayed on the panels; the fibers were not loose as the paint helped the fibers being stuck in their position
Summary
Composite-boards have the advantages of a homogeneous structure and the use of residual raw materials. Many studies have been carried out to decrease WA and TS, and find methods for limitation of formaldehyde emission as well as promotion of the quality of the resins (Valenzuela et al 2012). In this connection, nano-materials can be used in composite panels as an in-process treatment (IPT). High thermal conductivity of nano-metals (Saber et al 2013, Yu et al 2012) was used to accelerate production rate at industrial scale and to decrease liquid permeability
