Purpose of Review

The development of eco-friendly panels is one of the major issues for the wood industry, particularly in terms of developing new adhesive systems for reducing harmful emissions and dependence from fossil fuel resources. Among the plethora of various possible solutions, liquefied wood products have demonstrated promising features to decrease the use of petroleum-based amino resins. A meta-analysis was carried out to develop a quantitative synthesis of the state of the art of the application of liquefied wood products for particleboard manufacturing, investigating their effects on the board’s properties.

Recent Findings

The results from meta-analysis revealed that the application of liquefied wood products does not significantly deteriorate the mechanical properties of particleboards. It has also been observed that there is no negative influence on the formaldehyde content of the panel, mostly when liquefied wood products are applied in mixture with commercial resin. The most interesting observation is that the performance of the boards was not affected by the type of feedstock used for liquefaction.

Summary

The option to apply liquefied wood products has the potential to significantly decrease the application of commercial formaldehyde-based resins without leading to a deterioration of the properties of the panels. It is however important to note that there is currently a limited number of studies on this topic. The meta-analysis showed a notable variability of the effect sizes in the trials. Further study is needed to determine the outcomes and the benefits for the use of liquefied wood products on an industrial level.

液化木制品在刨花板制造中的应用：荟萃分析综述

审查目的

环保板材的开发是木材工业的主要问题之一，特别是在开发新的粘合剂系统以减少有害排放和对化石燃料资源的依赖方面。在众多可能的解决方案中，液化木制品已显示出减少石油基氨基树脂使用的有前景的特性。我们进行了一项荟萃分析，对液化木产品在刨花板制造中的应用现状进行定量综合，研究它们对板材性能的影响。

最近的发现

荟萃分析结果表明，液化木制品的应用并没有显着降低刨花板的机械性能。还观察到，主要是当液化木制品与商用树脂混合使用时，对板材的甲醛含量没有负面影响。最有趣的观察是，板的性能不受用于液化的原料类型的影响。

概括

选择使用液化木制品有可能显着减少商用甲醛基树脂的使用，而不会导致板材性能恶化。但值得注意的是，目前关于这一主题的研究数量有限。荟萃分析显示试验中效应大小存在显着差异。需要进一步研究以确定在工业层面使用液化木产品的结果和效益。
