钢铁表面喷砂除锈技术,是指运用一定规格尺寸的磨料(石英砂、河砂、铁砂、铁丸等),在一定的空气压力下,喷射到钢铁表面,利用磨料本身的硬度、冲击韧性和棱角,将钢铁表面的铁锈除去的一种腐蚀防护施工方法。这种方法比起其它的除锈方式,诸如化学除锈、手工除锈、动力工具除锈等方法来看,有比较明显的优点,它的除锈质量高,表面粗糙度好,对于大件设备具有较高的除锈工作效率。但它也有缺点,即大量粉尘污染环境,严重危害操作人员的健康。然而,在实际工作中,特别是在许多重要的腐蚀防护施工中,对钢铁表面除锈质量要求较高、有的规定要达到化工部颁布一级或二级标准,显然只有使用喷砂除锈才能达到要求。所以,即使喷砂除锈存
Sand blasting steel surface technology, refers to the use of a certain size of the abrasive (quartz sand, river sand, iron sand, iron balls, etc.), under certain air pressure, spray to the steel surface, the use of abrasive hardness, impact toughness And edges and corners, the steel surface rust removed a corrosion protection construction methods. This method compared to other methods of rust removal, such as chemical rust, hand rust, power tools rust and other methods, there are obvious advantages, its high quality rust, the surface roughness is good, for large Equipment has a high rust efficiency. But it also has the disadvantage that a large amount of dust pollutes the environment and seriously endangers the health of operators. However, in practical work, especially in many important corrosion protection construction, the quality requirements of steel surface rust removal higher, and some regulations to achieve the Ministry of Chemical Industry issued a or two standards, apparently only use sandblasting rust To meet the requirements. So, even sandblast rust save
