For post cementation , bis - core liquid catalyst must be used instead of the paste catalyst in order to lower the viscosity of the cement 关于桩的粘结， bis - core液体催化剂可以代替催化糊剂以降低水门汀的粘度。
Results : the mechanical properties of bone cement were improved by adding a certain proportion of chitin , aluminum borate and / or demineralized rabbit bone 几种水门汀中，羟基磷灰石人工骨的晶须加强型和脱矿骨甲基丙烯酸正丁酯水门汀的机械强度较好。
Different proportion of chitin , aluminum borate , and / or demineralized rabbit bone were added into different types of bone cement to strengthen the mechanical properties 结果：硼酸铝晶须和玻璃纤维对各种骨水门汀的强度均有增强作用，脱矿骨能显著提高甲基丙烯酸正丁酯水门汀的机械强度。
