Recent development in binderless fiber-board fabrication from agricultural residues: A review

Abstract

The manufacturing of fiberboard from wood fiber with the help of adhesive is highly developed and widely commercialized technique. However, with an increasing concern over health issues and biomass conservation, the fiberboards from agriculture residues with or without using adhesives are under intensive investigation. In last three decades, several researches have been done various methods and technique dealing the development of binderless fiber boards such as wet process and dry process. This review article also covered pretreatments of fiber which helps to find out optimum criteria for fabrication of fibreboards. Fibre sizes in fibreboard were studied and found that the dimensions of fibres effect the physical, mechanical and thermal properties. The pressing time and temperature influence the internal bonding of binderless fibreboards. The mechanical and thermal properties of binderless fibresboard were discussed on various pressing time and temperature and compared with different type fibreboards. Effect of hygrothermal properties on the physical, mechanical and thermal behavior of binderless were also discussed. This review summarized various aspects of self-bonding mechanism in binderless fibresboard with a focus on agriculture residues based raw materials. Various aspects of binderless fiberboard manufacturing such as raw material suitability, effects of pretreatments and manufacturing process on physical, mechanical and thermal properties are discussed. The chemical changes in fiber during pretreatments and hot pressing is also discussed in detail. These binderless fiberboard showed the suitability in use for indoor applications due to its non-toxic characteristics.

Eco-Friendly, High-Density Fiberboards Bonded with Urea-Formaldehyde and Ammonium Lignosulfonate

“…The fabricated HDF panels had very satisfactory MOR values, ranging from 30.99 N·mm −2 to 40.47 N·mm −2 , meeting the EN 622-2 standard requirements for HDF panels in humid conditions (MOR ≥ 30 N·mm −2 ) [ 91 ]. MOR and MOR of HDF may be affected by a number of factors that are discussed in [ 93 ]. According to that study, the fiber dimensions have a significant effect on the physical, mechanical, and thermal properties of HDF panels.…”

The role of lignin in wood working processes using elevated temperatures: an abbreviated literature survey

“…Wood-based binderless fibreboards without synthetic resin binders have been produced for at least 80 years: several types of bio-raw material were used for binderless boards, for example wood bark (Chow 1975;Wellons and Krahmer 1973;Geng et al 2006;Gao et al 2011), rice and wheat straw (Zhao et al 2013;Kurokochi and Sato 2015a, b), kenaf (Xu et al 2004), banana stems (Nongman et al 2016), coconut husks (van Dam et al 2004;2006), bagasse (Mobarak et al 1982), oil palm (Hashim et al 2012;Baskaran et al 2015), soybean straw (Song et al 2020) and bamboo (Shao et al 2009) etc. Recently, a review work on binderless fibreboards from agricultural residues was published summarizing the related studies (Nasir et al 2019).…”
