  • 不锈钢岗亭划痕和脏污处理的12个技巧

划痕:为了防止工艺润滑剂或生成物、污物积留,必须对不锈钢岗亭划痕和其它粗糙表面进行机械清理。

Scratch: In order to prevent the accumulation of process lubricants or products and dirt, scratches and other rough surfaces of stainless steel pavilions must be mechanically cleaned.

锈斑: 不锈钢岗亭在制作前或制作过程中有时会看到不锈钢产品或设备上生锈,这说明表面受到严重污染。设备投入使用前必须把锈清除掉,彻底清理过的表面应通过铁试验或水试验进行检验。

Rust spot: Stainless steel kiosks are sometimes rusted on stainless steel products or equipment before or during production, which indicates that the surface is seriously polluted. The rust must be removed before the equipment is put into use. The thoroughly cleaned surface should be inspected by iron test or water test.

浮铁粉或嵌入的铁: 在不锈钢岗亭的表面上,游离铁会生锈并使不锈钢岗亭产生腐蚀。因此,必须清除。浮粉一般可随粉尘一起清除掉。有些粘着力很强,必须按嵌入的铁处理。不锈钢岗亭在制作的过程中,不锈钢表面除粉尘外,铁的来源很多,其中包括用普通碳钢钢丝刷清理和用以前在普通碳钢,低合金钢或铸铁件上使用过的砂子、玻璃珠或其它磨料进行喷丸处理,或在不锈钢岗亭部件及设备附近对前面提到的非不锈钢制品进行修磨。在下料或吊过过程中如果不对不锈钢采取保护措施,钢丝绳、吊具和工作台面上的铁很容易嵌入或玷污表面。订货要求和制作后检查可以防止并发现游离铁的存在,ASTM标准A380[3]规定了检查不锈钢表面铁或钢微粒的铁锈试验法。

Floating iron powder or embedded iron: On the surface of stainless steel pavilions, free iron rusts and corrodes stainless steel pavilions. Therefore, it must be cleared. Floating powder can generally be removed with dust. Some have strong adhesion and must be treated with embedded iron. In the process of making stainless steel pavilion, there are many sources of iron besides dust on the surface of stainless steel, including cleaning with ordinary carbon steel wire brush and peening with sand, glass beads or other abrasives previously used in ordinary carbon steel, low alloy steel or cast iron castings, or grinding the aforementioned non-stainless steel products near the parts and equipment of stainless steel pavilion. If protective measures are not taken for stainless steel in the process of cutting or lifting, the steel wire rope, hanger and iron on the working table surface can easily be embedded or stained. Ordering requirements and post-production inspection can prevent and detect the existence of free iron. ASTM standard A380 [3] prescribes a rust test method for inspecting iron or steel particles on stainless steel surfaces.

当要求绝对不能有铁存在的时候,应该使用这种检验方法。如果结果令人满意,应用干净的纯水或硝酸对表面进行洗涤,直到深蓝色完全消失。正如标准A380[3]指出的如果铁锈试验溶液不能全部清除干净,不推荐在设备的工艺表面,即用来生产人类消费品的直接接触表面采用这种试验方法。比较简单的试验方法是在水中暴露12~24小时,检查是否有锈斑。这种试验灵敏性差,而且耗时。这些都是检测试验,不是清理方法。如果发现有铁存在,必须用后面介绍的化学和电化学的方法进行清理。

This method should be used when it is absolutely impossible for iron to exist. If the results are satisfactory, wash the surface with clean water or nitric acid until the dark blue disappears completely. As standard A380 [3] points out, if the rust test solution can not be completely cleaned, it is not recommended to use this test method on the process surface of the equipment, that is, the direct contact surface used to produce human consumer goods. The simpler test method is to expose to water for 12 to 24 hours to check for rust spots. This test is not sensitive and time-consuming. These are tests, not cleaning methods. If iron is found, it must be cleaned up by chemical and electrochemical methods described later.

粉尘: 不锈钢岗亭所放置的位置通常都会有粉尘,空气中常带有许多粉尘,它们不断地落在岗亭的表面。我们可以用水或碱性溶液去除掉落在岗亭表面的粉尘。不过,有附着力的尘垢需要使用高压水或蒸气进行清理。

Dust: Stainless steel pavilions are usually placed in the position of dust, often with a lot of dust in the air, they continue to fall on the surface of the pavilion. We can use water or alkaline solution to remove dust falling on the surface of the pavilion. However, adherent dust needs to be cleaned up with high-pressure water or steam.

残余粘合剂:撕掉胶带和保护纸时,粘合剂总有一部分残留在不锈钢表面。如果粘全剂还没硬,可以用有机熔剂去除。但是,当曝露在光和/或空气中时,粘全剂变硬,形成缝隙腐蚀的腐蚀源。然后需要用细磨料进行机械清理。

Residual adhesives: When tearing off tape and protective paper, some of the adhesives remain on the surface of stainless steel. If the adhesive is not hard enough, it can be removed with organic flux. However, when exposed to light and/or air, the adhesive hardens and forms the corrosion source of crevice corrosion. Then fine abrasives are needed for mechanical cleaning.

焊接飞溅:不锈钢岗亭在焊接时,焊接飞溅与焊接工艺有很大关系。例如:GTAM(气体保护钨极电弧焊)或TIG(惰性气体保护钨极焊)没有飞溅。但是,采用GMAW(气体保护金属电弧焊)和FCAW(带焊剂芯的电弧焊)两种焊接工艺时如果焊接参数使用不当会造成大量飞溅。出现这种情况时,必须调整参数。如果要解决焊接飞溅的问题,焊接前应在接头的每一边涂上防溅剂,这样可以消除飞溅物的附着力。焊完后可以很容易地将这种防溅剂及各种飞溅物清理掉,可不损伤表面或带来轻微损伤。

Welding spatter: The welding spatter of stainless steel Pavilion is closely related to the welding process. For example, there is no spatter in GTAM (gas shielded tungsten arc welding) or TIG (inert gas shielded tungsten arc welding). However, the improper use of GMAW (gas shielded metal arc welding) and FCAW (flux cored arc welding) will cause a lot of spatter. When this happens, the parameters must be adjusted. If the problem of welding spatter is to be solved, the splash inhibitor should be applied on each side of the joint before welding, so as to eliminate the adhesion of the splash. After welding, it is easy to clean up the splashproof agent and all kinds of splashes without damaging the surface or causing minor damage.
