Development of wood and wood ash-based hydroxyapatite composites

为了有效利用废木灰，用木灰基羟基磷灰石悬浮液浸渍木材制备了木材/羟基磷灰石复合材料。功能性评价的结果是，HAP处理可以提高处理木材的阻燃性能。木材-羟基磷灰石复合材料的室外老化试验结果表明，羟基磷灰石处理对木材在阳光照射下的褪色有一定的延缓作用，但对木材腐烂过程没有明显的延缓作用。在HAP处理的木材上也没有证实耐热性，因为HAP复合材料在室外喂养试验中受到了显著的热害。

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.
