The use of nanocellulose in the production of medium density particleboard panels and the modification of its physical properties

Abstract

Wood-based panel applications recently have expanded and become increasingly competitive, especially within the furniture and civil construction industries. To remain competitive, such products must present physical properties that meet consumer needs. In this context, the incorporation of nanomaterials is gaining momentum, mainly as a means to improve the physical characteristics of panels, thereby expanding their applications. The aim of this study was to evaluate the physical properties of medium density particleboard (MDP) panels after adding various proportions of nanocellulose in place of water to the urea-formaldehyde (UF) adhesive in MDP panel production. The results showed that the addition of nanocellulose resulted in no significant statistical difference in the density and moisture content of the panels. When tested for thickness swelling, only the panel with 100% nanocellulose solution exhibited a significantly higher value. The panels were subjected to scanning electron microscopy (SEM) analysis, which showed that the addition of nanocellulose led to a more polished, less irregular surface. Such physical effects of nanocellulose can potentially make panels more suitable for coating applications. The feasibility of coatings on nanocellulose MDP panels can be verified through future tests to determine the surface roughness of the panels.

Performance properties of particleboard panels modified with nanocellulose/boric acid

“…The authors declared that particleboard panels met the industry requirements in terms of mechanical properties. Hansted et al (2019) studied the physical properties of mediumdensity particleboard (MDP) panels after adding various proportions of nanocellulose to the UF-adhesive in MDP panel production. The authors declared that the addition of NC presented promising results from physical tests.…”

A new model based on principal component regression-random forest for analyzing and predicting the physical and mechanical properties of particleboard

“…Particleboard is considered a renewable product, and it is generally used in many industries, e.g., for interior fitments (including furniture), construction, transportation, etc. (Hansted et al 2019). Further studies and analyses regarding the physical properties and production process of particleboards would be beneficial for the improvement of their production processes and quality control.…”

Interfacial interactions between urea formaldehyde and cellulose nanofibrils (CNFs) of varying chemical composition and their impact on particle boards manufacture (PBs)

“…Their production and utilization has been increasing over the past few decades due to the good and useful properties and the environmental bene ts they present (Hansted et al 2019). Among the woodpanel alternatives, particle board, ber board, and oriented strand board (OSB) are some of the most frequently used (Ayrilmis et al 2016;Hansted et al 2019). Speci cally, for particle boards manufacturing, three layers are normally formed where larger particles are used for the core layer, improving the mechanical properties.…”

“…Speci cally, for particle boards manufacturing, three layers are normally formed where larger particles are used for the core layer, improving the mechanical properties. Thinner particles are used for the two outer layers in order to obtain a smooth surface (Hansted et al 2019).…”

“…In recent years, nanocellulose has been increasingly studied for its many intriguing properties and immense potential. On the side of wood composites research, micro and nano brillated cellulose have been recently investigated as a ller for wood adhesives in particle boards (Mahrdt et al 2016;Hansted et al 2019; Morais Júnior et al 2020), OSB (Veigel et al 2011(Veigel et al , 2012, and plywood (Kawalerczyk et al 2020). Veigel et al (2011) studied the effect of the addition of CNF bers into UF for wood beams.…”
