Development of wood and wood ash-based hydroxyapatite composites

为了有效利用废弃木灰，采用木灰基羟基磷灰石（HAp）悬浮液浸渍木材制备木材/HAp复合材料。作为功能性评估的结果，HAp处理可以增强处理木材的阻燃性。木材-HAp复合材料的室外耐候性试验结果表明，HAp处理对经处理的木材因阳光照射而褪色具有一定的延缓作用，尽管没有证实对木材腐烂进程的延缓作用。在HAp处理的木材上也没有证实耐铝热剂性，因为HAp复合材料遭受显著的铝热剂损害，特别是在户外喂养测试中。

For making efficient use of waste wood ash, the wood and Hydroxyapatite (HAp) composite was produced by impregnating woods with the wood ash-based HAp suspension. As a result of functionality assessment, the HAp treatment can enhance the flame retardancy of the treated woods. The result of outdoor weathering tests with the wood-HAp composite imply that the HAp treatment have some retarding effect on a color fading of the treated woods by the sunlight irradiation, although no retarding effects against a wood rotting progress were confirmed. The thermite resistance was also not confirmed on the HAp treated woods, because the HAp composites suffered striking thermite damage particularly in the outdoor feeding tests.
