摘　　要：为了解决大理石切割表面质量差的问题,通过添加高分子聚合物(聚丙烯酰胺)辅助磨料射流切割大理石,达到降低能耗、改善切割表面质量等目的。采用正交试验法,分析切割速度、高分子聚合物质量浓度、靶距对大理石切割表面粗糙度和切缝宽度的影响。结果表明,影响程度由大到小为切割速度、高分子聚合物质量浓度、靶距,最优方案为切割速度200 mm/min、高分子聚合物质量浓度0.3 g/L、靶距6 mm。添加高分子聚合物可以降低射流液体之间的摩擦阻力,起到流体减阻的作用。For the problem of poor surface quality in marble cutting,when the marble is cut,we add a polymer(polyacrylamide)auxiliary abrasive jet to reduce energy consumption and improve the surface cutting quality.The orthogonal test method is used to analyze the effects of knife speed,polymer concentration,and target distance on the roughness of the marble cutting surface and the width of the cutting seam.The results show that the primary and secondary effects are knife speed,polymer concentration,and target distance,and the optimal program is a cutting speed of 200 mm/min,polymer concentration of 0.3 g/L,and target distance of 6 mm.Adding polymer can reduce the friction resistance between the jet liquid to achieve the effect of fluid drag reduction.
