喷砂清理手册

[中文适用范围]： 喷砂清理可以定义为一种机械预处理过程，其中适当的固体颗粒流以足够的速度推进到工作表面上，以在与工件接触时产生清洁或研磨作用。喷砂清理可用于多种目的。它是一种行之有效的方法，用于去除铸件中的砂子以及锻件、轧机产品或热处理零件中的毛刺或氧化皮；提高可加工性；并尽量减少实际操作中干扰的可能性。除此用途外，喷砂清理还可以为下游工业涂料提供合适的表面。所有这些目标通常可以在一次操作中实现。作为一般理解，本文件仅涉及喷砂清理。任何对喷丸或其他工艺的提及仅是为了解释与喷砂清理相关的背景或概念。 [外文原描述]： Blast cleaning may be defined as a mechanical pre-treatment process in which a suitable stream of solid particles is propelled with sufficient velocity against a work surface to cause a cleaning or abrading action when it comes in contact with the workpiece.Blast cleaning may be employed for a variety of purposes. It is a well-established method for removing sand from castings and burrs or scale from forgings, mill products, or heat treated parts; to promote machinability; and to minimize the possibility of interference in actual operation. In addition to this use, blast cleaning also produces a suitable surface for downstream industrial coatings. All these objectives are often accomplished in the one operation.As a general understanding, this document pertains to blast cleaning only. Any reference to shot peening or other processes is only to explain a context or concept related to blast cleaning. Processes prior to and/or after blast cleaning are entirely possible, but they do not take primary context in this document.Cross Reference: J441_201310,J444_201209,J827_201310
