Preparation method of ultra-pure magnesium phosphate bone binder
The invention provides a preparation method of an ultra-pure magnesium phosphate bone binder. The preparation method comprises the following steps: purifying magnesium chloride in a recrystallizationmanner, adding ammonium carbonate for a synthetic reaction to obtain super-pure basic magnesium carbonate, carrying out calcining to prepare light magnesium oxide, adding starch for gelatinization andpelletization, and carrying out calcining at 1500 DEG C or above to produce the super-pure dead-burnt magnesia, wherein the goal of preparing high-purity magnesium oxide is achieved by using the characteristics that magnesium chloride and ammonium chloride decompose and escape at high temperature; and subjecting reagent-grade potassium hydroxide and phosphoric acid to mixing and reacting, carrying out filtering, crystallizing, dissolving, recrystallizing, drying and the like to obtain solid salts of potassium hydrogen phosphate and potassium dihydrogen phosphate, metering and mixing the potassium hydrogen phosphate and the prepared ultra-pure magnesia, and carrying out jet milling to obtain potassium magnesium phosphate solid powder, namely the solid component of the magnesium phosphate bone binder. When in use, the bone binder is mixed with prepared solutions such as a sodium citrate solution and a potassium citrate solution, is used for on-site gelatinization and solidification, andhas the advantages of high purity, quick coagulation, high strength, simple operation and the like.
本发明提供一种超纯磷酸镁骨粘结剂制备方法，采用重结晶的方式将氯化镁进行提纯，加入碳酸铵进行合成反应，获得超纯碱式碳酸镁，煅烧制备轻质氧化镁，加入淀粉胶凝制球后在1500℃以上煅烧生产超纯重烧镁砂，利用了氯化镁与氯化铵在高温下分解与逸出的特点，实现高纯氧化镁制备的目标；试剂级的氢氧化钾、磷酸混合反应，经过滤，结晶、溶解、再结晶和干燥等步骤获得磷酸氢钾、磷酸二氢钾的固体盐，后将磷酸氢钾盐与所制备的超纯镁砂计量混合后进行气流粉碎，获得磷酸钾镁固体粉末，即磷酸镁骨粘结剂的固体成分。该骨粘结剂在使用时与配制好的柠檬酸钠、柠檬酸钾等溶液进行混合，现场胶凝固化使用，具有纯度高、凝结快、强度高、操作简单等优点。
