浸渍改性提高速生材尺寸稳定性的研究进展
Research Progress on Impregnation to Improve the Dimensional Stability of Fast-Growing Wood
摘要
Abstract
The improvement of wood quality through modification techniques is one of the key strategies to alleviate the challenge of wood resource shortage.Among various wood modification methods,impregnation is particularly effective.This technique alters the structure of the wood cell wall and/or fills the cell lumen,thereby significantly enhancing the dimensional stability,durability,and mechanical properties of the wood.Additionally,it enhances functional characteristics such as fire retardancy and resistance to decay and insect infestation.Common modifiers include thermosetting resins,organic monomers,biomass-based modifiers,and organic-inorganic compound modifiers.The mechanisms by which these modifiers enhance dimensional stability primarily involve the swelling of the wood cell wall,the reduction of water absorption,and the prevention of water molecules from entering the wood,thereby improving resistance to shrinkage and swelling.Biomass-based modifiers such as furfuryl alcohol resins,small-molecule sugars,and lignin have attracted significant attention due to their environment-friendly and biodegradable properties.These modifiers not only enhance wood performance but also reduce the dependence on fossil resources.To further improve modification effectiveness,future research needs to focus on the synthesis of novel modifiers and the optimization of modification processes.Furthermore,leveraging artificial intelligence,it can be achieved to optimize the modification process,predict performance,and calibrate parameters.关键词
