This part of ISO 8504 describes abrasive blast-cleaning methods for the preparation of steel surfaces before coating with paints and related products. It also contains information on the effectiveness of the individual methods and their fields of application. ISO 8504 is applicable to new and corroded steel surfaces and to steel surfaces that are uncoated or have been previously coated with paints and related products. For limitations, see note 2. NOTE 1 These methods are essentially intended for hot-rolled steel to remove mill scale, rust, etc., but could also be used for cold-rolled steel of sufficient thickness to withstand the deformation caused by the impact of abrasive. NOTE 2 There are several items that should be included in the purchaser's procurement documents to supplement this part of ISO 8504. Items that should be considered as a part of surface preparation before coating are edge grinding, removal of grease and oil, porosity of welds, removal of weld spatter, removal of burrs and other sharp edges, grinding of welds, filling of pits and other surface imperfections that may cause premature failure of the coating system (see ISO 8501-3 for more information) and the removal of water-soluble contaminants.
工业内窥镜的主要作用是对人眼无法识别的管道内部,仪器设备而内部等进行检测,主要检查管道及焊缝表面有无裂纹、白点、砂眼、气孔和夹渣等。在检盘前应消除工件焊缝表面飞溅物、氧化皮、凹坑、油漆及锈蚀等。由于工业管道内窥镜的使用环境复杂,通常要根据具体的检测对象位置及要求来确定使用内窥镜的种类,至少要考虑检测的位置、方向、通路等要素,复杂产品往往要求多种型号内窥镜配合使用。 ...
请注意,在擦拭仪器时可不能发生仪器表面或其他组件的腐蚀或二次污染。 2、气相色谱仪电路板的维护和清洁 在气相色谱仪准备好进行维护之前,请关闭仪器的电源。首先,用仪器空气或氮气吹扫电路板和电路板插槽,使用软刷清洁电路板和插槽的多尘部分,仔细清理它。在操作过程中尽可能戴手套,以防止手上的静电或汗水影响电路板上的某些部件。...
