东丽柱塞泵型号A10VS018DFR1/31R-一般地，加大水口底圆弧半径有利于分散应力。一旦发现有裂纹存在，可在裂纹根部打一圆孔，这样能阻止裂纹进一步蔓延；为减少切割强研磨性材料时锯片基体水口环形带的磨损，可采用带护齿结构的锯片。采用消音基体可降低锯片切割时产生的尖锐高音频噪声。消音基体多为复合型材料构成，如：基体中间加一层吸音系数大的材料（铜箔、橡胶、弹性高分子材料）；采用厚薄钢板复合；将基体匙形水口用吸音较好的铜片填紧；用激光顺着基体水口底部和中心孔沿径向有规则地切出“S”型、“C”型细缝，在激光切缝的基础上再向缝中灌注一些特殊的树脂材料效果会更好。

一般所讲的老化主要是讲石材的风化。是指石材受自然环境中各种因素作用的侵蚀而使石材分崩离析，这种现象叫石材的风化。根据其作用力的不同，我们可将石材的风化分为物理性和化学性二种。化学作用造成石材风化的因素有如下方面：1.氧化反应作用：石材的矿物质元素成分被发生氧化反应，造成石材，体积增大，失去原有的光泽和弹性。如：锈斑。溶解作用：通常是以水为溶剂，当其中含有碳酸根离子、硫酸根离子或根离子等及有机物时，溶解力更大。
