“…For wood drying, researches have been focused on drying methods of timbers, including vacuum drying (He et al 2013), microwave drying (Li et al 2005), superheated steam drying (Cheng et al 2004), radio-frequency vacuum drying , combined drying, and energy-saving drying (Gu 2007). The problems encountered during drying process were also focused on, such as fluid-flow characteristics (Miao and Gu 2003), coupled transfer of heat and mass (Lu et al 2005(Lu et al , 2012, drying kinetics, moisture monitoring , dynamic moisture distribution (Cai 2008), stress release (Cheng et al 2004), shrinkage , creep (Zhan and Avramidis 2011), and optimal control strategies (Li et al 2008b;Ge and Chen 2014). For wood adhesives and gluing technology, research themes included synthesis, polycondensation, and curing mechanisms of adhesives such as urea-formaldehyde resin Gao et al 2015b), phenolic resin (Mo et al 2014), amino resin, and emulsions.…”
