METHOD FOR PRODUCING POROUS COMPOSITE MATERIAL
The invention relates to a method for manufacturing an HAP/beta-TCP porous composite material. The method at least comprises the steps of providing a dry powder mixture, providing a granulation mixture and executing an annealing step. The dry powder mixture comprises 40 wt% to 55 wt% of hydroxyapatite, 25 wt% to 40 wt% of beta-tricalcium phosphate, and 10 wt% to 20 wt% of polyethylene (PE) particles having a particle size of 250 [mu] m to 600 [mu] m. The dry powder mixture and the sugar aqueous solution are mixed to form a particle mixture, and the annealing step is performed. The temperature control procedure of the annealing step comprises raising the temperature from 80 DEG C to 100 DEG C to 400 DEG C to 600 DEG C at a temperature rise rate of 20 DEG C to 30 DEG C per hour, and then keeping the temperature.
一种HAP/β‑TCP多孔复合材料的制造方法，该方法至少包含提供一干粉混合物、提供一造粒混合物以及执行一退火步骤。干粉混合物包含40wt％至55wt％的氢氧基磷灰石、25wt％至40wt％的β‑三钙磷酸盐以及10wt％至20wt％的粒径为250μm至600μm的聚乙烯(PE)颗粒。干粉混合物与糖水溶液混合后形成一颗粒混合物，并进行该退火步骤。该退火步骤的温度控制程序包含以每小时20℃至30℃的升温速率从80℃至100℃提高到400℃至600℃，接着持温。
