抛丸是指通过机械的方法把丸料(钢丸)以很高的速度和一定的角度抛射到工作表面上,让丸料冲击工作表面,然后在机器内部通过配套的吸尘器的气流清洗作用,将丸料和清理下来的杂质分别回收,并且使丸料可以再次利用的技术。世界上第一台抛丸设备诞生于100年前,开始是在各种金属或非金属表面的去除杂质、氧化皮,增加粗糙度等方面上得到应用。经过百年的发展,抛丸工艺以及设备已经相当成熟,其应用也已经不仅仅是在各个重工业的工厂。随着世界上第一台水平移动式抛丸设备在美国佰锐泰克(BLASTRAC)诞生,其应用领域迅速扩展到混凝土表面处理和船舶甲板金属表面的处理上,并且直接引导了该行业的标准制订和行业施工工艺的规范。随着抛丸设备的不断改进和技术的成熟,抛丸工艺和设备已经进入欧美发达国家公路养护、桥梁施工和机场维护等领域。目前,抛丸技术和设备在国内的应用刚刚起步,本文介绍抛丸工艺及其设备在公路、桥梁、机场等领域的应用 Blasting refers to the mechanical method to the shot material (steel shot) at a high speed and angle projection to the work surface, so that the shot material impact the work surface, and then in the machine through the supporting vacuum cleaner airflow cleaning, The pellets and cleaned up impurities were recovered, and the pill can be reused technology. The world’s first shot blasting equipment was born 100 years ago, the beginning is in a variety of metal or non-metallic surfaces to remove impurities, scale, increase roughness and so on to be applied. After a hundred years of development, shot blasting process and equipment have been quite mature, and its application has not only been in various heavy industry factories. With the birth of BLASTRAC, the first horizontal mobile shot blasting machine in the world, its application has rapidly expanded to the treatment of concrete surfaces and ship deck metal surfaces and has led directly to the industry’s standard-setting And industry construction process specifications. With the continuous improvement of shot blasting equipment and technology maturity, shot blasting technology and equipment have entered the developed countries in Europe and America road maintenance, bridge construction and airport maintenance and other fields. At present, the application of shot blasting technology and equipment in China has just started, this article describes the application of shot blasting technology and its equipment in the fields of roads, bridges, airports and other fields
