喷丸清理(喷砂)在金属和非金属涂覆前表面处理中的地位和作用已逐渐为人们所认识和重视。喷丸清理(本文指压送式喷丸清理)以作业场所的不同有室外喷丸清理和室内喷丸清理之分。基于磨料来源和经济性考虑,室外喷丸清理常以砂和炉渣制成品等作磨料,此类磨料通常无回收价值,故统称消耗性磨料。采用消耗性磨料进行室外喷丸清理,粉尘污染是最为令人头痛的问题,因此,这类喷丸清理常受到有关法令或法规的限制以及人们的抵制。室外喷丸清理过程中出现的粉尘主要有三个来源: (1) 磨料中存在的尘土或灰尘; (2) 磨料颗粒高速撞击工件表面而破碎,所产
Shot peening (sand blasting) in the metal and non-metallic surface treatment before coating the role and role has gradually become known and valued. Shot peening (this refers to the pressure peening shot peening) to work in different outdoor peening and indoor shot blasting points. Based on the abrasive source and economic considerations, outdoor shot peening often sand and slag products such as abrasive, such abrasive usually without recovery value, it is said that the consumable abrasive. The use of abrasive abrasives for outdoor shot blasting is the most troubling problem of dust pollution. Therefore, such shot peening is often limited by laws and regulations and people’s resistance. There are three main sources of dust present during outdoor shot peening: (1) dust or dust present in the abrasive; (2) abrasive particles crashing at the surface of the workpiece at high speed and are broken
