金刚石钻头参数与钢筋混凝土的适应性研究

Research on Adaptability of Parameters of Diamond Bit to Steel Reinforced Concrete

根据钢筋砼的特性，从理论分析结合实践经验合理选择了金刚石钻头的主要性能参数。ＧＷ２号配方对钢筋砼的适用性较好，胎体性能稳定，并选用了粒度为４０～５０目、浓度为４５％的较高品级金刚石与该胎体相匹配，在生产使用中取得了较好的钻进效果。

Based on the property of steel reinforced concrete, main parameters are determined by combining theoretical analysis with practice experience. Formula GW 2 of matrix has good adaptabilily to steel reinforced concrete and its matrix property is stable, especially matched with better grade diamond of grain size 40～50 mesh and concentration 45%, so the penetration result is ideal in practice.
