现在济南不锈钢雕塑在城市建设中起着至关重要的作用,而由于经常放置在室外,所以难免会有一些损伤。Now Ji'nan stainless steel sculpture in urban construction plays a vital role, and because often placed in the outdoor, so there will inevitably be some damage.
1.焊接引弧斑痕:焊工在山东不锈钢雕塑金属表面引弧时,会造成表面粗糙缺陷。保护膜受损,留下潜在的腐蚀源。焊工应在已经焊好的焊道上或在焊缝接头的侧边引弧。然后将引弧痕迹熔入焊缝中。Welding arc spot welder in Shandong: stainless steel sculpture metal arc surface, will cause surface defects. Protection film damage, leaving potential corrosion sources. The welder shall have good welding in welding or welding joint in the side of the arc. Then the arc trace is melted into the weld.
2.锈斑:济南不锈钢雕塑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和/或水试验进行检验。Rust: Ji'nan stainless steel sculpture making before or in the process of making sometimes see rust stainless steel products or equipment, the surface is seriously polluted. Rust must be removed before equipment is put into use. Thoroughly cleaned surfaces shall be inspected by iron test and / or water test.
3.焊接缺陷:焊接缺陷如:咬边、未焊透、密集气孔和裂纹不仅降低接头的牢固性,而且还会成为缝隙腐蚀的腐蚀源。改善这种结果进行清理操作时,它们还会夹带固体颗粒。山东不锈钢雕塑公司提醒,这些缺陷可通过重新焊接或修磨后重焊进行修补。Welding defects: welding defects such as: undercut, non penetration, dense pores and cracks not only reduce the firmness of the joint, but also become a corrosive source of crevice corrosion. To improve this result when cleaning operations, they will also entrained solid particles. Shandong stainless steel sculpture company reminded that these defects can be repaired by re welding or regrinding after repair.
4.划痕:为了防止工艺润滑剂或生成物和/或污物积留,必须对划痕和其它粗糙表面进行机械清理(如干喷砂,防火包磨料用玻璃珠)。Scratch: mechanical cleaning of scratches and other rough surfaces (e.g. dry blasting, fire resistant coated glass beads) must be done in order to prevent process lubricants and / or dirt retention.
5.油和油脂:有机物质如:油,油脂甚至指印都会成为局部腐蚀的腐蚀源。由于这些物质能起屏障作用,它们会影响化学和电化学清理效果,因而必须彻底清理掉。Oil and grease: organic substances such as oil, grease and even fingerprints will become the source of local corrosion corrosion. Since these substances can act as barriers, they can affect chemical and electrochemical cleaning effects and must be completely cleaned up.
6.油漆、粉笔和标记笔印:这些污染物的影响与油和油脂的影响相似。建议用干净的刷子和干净的水或碱性清洗剂进行洗涤,也可以使用高压水或蒸汽冲洗。Paint, chalk and marker printing: the effects of these contaminants are similar to those of oils and fats. It is recommended to use a clean brush and clean water or alkaline cleaning agent for washing, can also use high-pressure water or steam wash.
7.热回火色和其它氧化层:热回火色是由于在高温或长时间在较高度下停留所致。当出现任何一种这类氧化层时,金属表面的铬含量都会降低,造成这些区域的耐腐蚀性降低。济南不锈钢雕塑在这种情况下,不仅要消除热回火色和其它氧化层,还应对它们下面的贫铬金属层进行清理。Back fire heat and other oxidation layer: back fire heat is due to the high temperature or long time at a height of stay by. When any such oxide occurs, the chromium content of the metal surface will be reduced, resulting in reduced corrosion resistance in these areas. Ji'nan stainless steel sculpture in this case, not only to eliminate the back fire heat and other metal oxide layer, the chromium depleted layer also deal with them the following cleaning.
8.粉尘:山东不锈钢雕塑公司制作经常是在有粉尘的场地进行,空气中常带有许多粉尘,它们不断地落在设备表面。它们可以用水或碱性溶液去除掉。不过,有附着力的尘垢有机膨润土需要高压水或蒸气进行清理。Dust: Shandong stainless steel sculpture company is often produced in the dust site, often with a lot of dust in the air, they continue to fall on the surface of the equipment. They can be removed with water or alkaline solution. However, there is dirt organic bentonite adhesion requires high pressure water or steam cleaning.
9.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,济南不锈钢雕塑当曝露在光或空气中时,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 adhesive: tear tape and protective paper, adhesive is always a part of residues on the surface of stainless steel. If the agent is not sticky hard, can be used to remove organic solvent. However, Ji'nan stainless steel sculpture when exposed to light or air, the viscosity agent harden, corrosion source forming crevice corrosion. And then need to fine abrasive mechanical cleaning.
