球墨井盖表面常用的保养清洗方法!

来源:http://www.kpp647.com添加时间:2019-09-24 16:12:33

井盖在户外经受风吹日晒,很容易变得又脏又旧,影响市容!今天山东球墨铸铁井盖厂家就给大家总结一下球墨井盖表面常用的保养清洗方法,希望对大家有所帮助!

Well covers are exposed to wind and sunshine outdoors, which can easily become dirty and old, affecting the city's appearance! Today, Shandong Ductile Iron Well Cover Factory will summarize the common maintenance and cleaning methods for the surface of Ductile Iron Well Cover, hoping to help you!

1、球墨铸件锈斑

1. Rust spots of nodular graphite castings

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 on stainless steel products or equipment is sometimes seen before or during manufacture, 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 and/or water test。

2、球墨铸件表面粉尘

2。 Dust on the Surface of Nodular Graphite Castings

铸钢件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,有附着力的尘垢需要高压水或蒸气进行清理。

The production of steel castings is often carried out in dusty sites. There are many dusts in the air, which constantly fall on the surface of equipment. They can be removed by water or alkaline solution. However, adherent dust requires high-pressure water or steam to clean up.

3、球墨铸铁件表面浮铁粉或嵌入的铁

3. Floating iron powder or embedded iron on the surface of ductile iron castings

在任何表面上,游离铁都会生锈并使不锈钢产生腐蚀。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。除粉尘外,表面铁的来源很多,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。

On any surface, free iron rusts and corrodes stainless steel. 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 addition to dust, there are many sources of surface iron, including cleaning with ordinary carbon steel wire brushes and peening with sand, glass beads or other abrasives previously used in plain carbon steel, low alloy steel or cast iron castings, or grinding of previously mentioned non-stainless steel products near stainless steel parts and equipment. If the stainless steel is not protected during the lifting process, the steel wire rope, hanger and iron on the working table surface can easily be embedded or stained.

4、球墨铸件划痕

4。 Scratch of Ductile Iron Castings

为了防止工艺润滑剂或生成物或污物积留,必须对划痕和其它粗糙表面进行机械清理。

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

5、粗糙的研磨和机加工

5。 Rough Grinding and Machining

研磨和机加工都会造成表面粗糙,留有凹槽,重叠和毛刺等缺陷。每种缺陷也可能使金属表面损伤到一定深度,以至于受损伤的金属表面无法通过酸洗,电抛光或喷丸等方法清理掉。粗糙表面能够成为发生腐蚀和沉积生成物的发源地,重焊前清理焊缝缺陷或清除多余的焊缝加强高都不能用粗磨进行研磨。对后一种情况,应再用细磨料研磨。

Grinding and machining can cause surface roughness, grooves, overlaps and burrs. Each defect may also cause metal surface damage to a certain depth, so that the damaged metal surface can not be cleaned up by pickling, electropolishing or shot peening. Rough surface can be the source of corrosion and deposition products. No rough grinding can be used to clean weld defects or remove excess weld reinforcement height before re-welding. In the latter case, fine abrasives should be used again.
