EIn order to reduce formaldehyde emissions, an experimental investigation of lightweight flax shives based particleboards, prepared using two different binders: bio-based lignin (lignosulfonate) and partially bio-based epoxy resin (greenpoxy 56), was undertaken. The flax based particleboards (with a target density of 500 kg/m³), were elaborated by a thermo-compression process using 20 wt% of binder content. The flax shives were directly valorised as they had no pre-treatment, in order to qualify their potential as a raw material. Bending, compression and fire resistance tests showed that the mechanical and flame performances of lignosulfonate-based particleboards were high compared to those of greenpoxy56 based panels. Nevertheless, the latter were found to have an interesting dimensional stability after water immersion and good insulating properties. Moreover, both lignosulfonate and greenpoxy 56 based particleboards met the minimum EN 15197 requirements for non-load bearing flaxboards for use in dry conditions (Type FB2). Such results illustrated the competitiveness of the studied particleboards, as bio-sourced structures, compared to urea-formaldehyde based panels.

E为了减少甲醛排放，对使用两种不同粘合剂制备的轻质亚麻碎屑刨花板进行了实验研究：生物基木质素（木质素磺酸盐）和部分生物基环氧树脂（greenpoxy 56）。亚麻基刨花板（目标密度为 500 kg/m³）通过热压工艺使用 20 wt% 的粘合剂制成。亚麻碎块直接升值，因为它们没有经过预处理，以证明其作为原材料的潜力。弯曲、压缩和耐火测试表明，与 greenpoxy56 基面板相比，木质素磺酸盐基刨花板的机械和阻燃性能更高。尽管如此，后者被发现在浸水后具有令人感兴趣的尺寸稳定性和良好的绝缘性能。此外，基于木质素磺酸盐和 greenpoxy 56 的刨花板均符合 EN 15197 对在干燥条件下使用的非承重亚麻板（FB2 型）的最低要求。这样的结果说明了所研究的刨花板作为生物来源结构与脲醛基面板相比的竞争力。
