There are many kinds of door frames. Stainless steel door pocket has gorgeous and bright visual and decorative performance, creating a luxurious atmosphere, which is not only beautiful, but also rich in color; It is also easy to scrub, so the damage to the door can also be reduced. Now this is the choice of many families. How should we clean and maintain the stainless steel door pocket? Next, Xiaobian will share some deep cleaning methods with you, hoping to help you.

1、锈斑

1. Rust spot

不锈钢门产品或设备在生产前或生产过程中有时会生锈，表明表面污染严重。设备投入使用前，一定除锈，完全清理干净的表面应进行铁试验和水试验。

Stainless steel door products or equipment sometimes rust before or during production, indicating serious surface pollution. Before the equipment is put into use, the rust must be removed, and the completely cleaned surface should be subjected to iron test and water test.

2、粉尘

2. Dust

生产通常在多尘的场所进行。空气中经常有大量灰尘，这些灰尘不断落在设备表面。它们可以用水或碱性溶液去除。然而，粘性灰尘需要用高压水或蒸汽清洗。

Production is usually carried out in dusty places. There is often a lot of dust in the air, which constantly falls on the surface of the equipment. They can be removed with water or alkaline solution. However, sticky dust needs to be cleaned with high-pressure water or steam.

3、浮铁粉或嵌铁

3. Floating iron powder or embedded iron

在许多表面，游离铁会生锈和腐蚀不锈钢门。因此，需要将其移除。漂浮的粉末通常可以与灰尘一起。有些具有很强的附着力，需要作为预埋铁处理。除灰尘外，还有许多表面铁的来源，包括用普通碳钢钢丝刷清洁的非不锈钢门产品，用砂、玻璃珠或其他以前用于普通碳钢、低合金钢或铸铁件的磨料进行喷丸处理，或在不锈钢门组件和设备上研磨。如果不锈钢门在下料或吊装过程中未加以保护，则工作台上的钢丝绳、吊具和铁容易嵌入或污染表面。

On many surfaces, free iron will rust and corrode stainless steel doors. Therefore, it needs to be removed. Floating powder can usually be removed together with dust. Some have strong adhesion and need to be treated as embedded iron. In addition to dust, there are many sources of surface iron, including non stainless steel door products cleaned with ordinary carbon steel wire brush, shot blasting with sand, glass beads or other abrasives previously used for ordinary carbon steel, low alloy steel or iron castings, or grinding on stainless steel door components and equipment. If the stainless steel door is not protected during blanking or hoisting, the steel wire rope, lifting appliance and iron on the workbench are easy to be embedded or pollute the surface.

4、划痕

4. Scratch

为防止工艺油或产品和/或污垢的积聚，需要对划痕和其他粗糙表面进行机械清洁。

To prevent the accumulation of process oil or products and / or dirt, mechanical cleaning of scratches and other rough surfaces is required.

5、热回收色等氧化层

5. Oxide layer such as heat recovery color

如果不锈钢门在焊接或打磨过程中在空气中加热到一定的高温，则焊缝两侧、焊缝下表面和焊缝底部都会出现氧化铬热回收色。与氧化保护膜相比，热回收颜色更薄，更明显。颜色取决于厚度，可以在彩虹、蓝色、紫色到浅黄色和棕色中看到。较厚的氧化物通常为黑色。这是由于长时间停留在高温或更高海拔造成的。当该氧化层出现时，金属表面的铬含量将降低，导致这些区域的耐蚀性降低。在这种情况下，不仅应去除热回收颜色和其他氧化层，还应清洁其下方的贫铬金属层。

If the stainless steel door is heated to a certain high temperature in the air during welding or grinding, chrome oxide heat recovery color will appear on both sides of the weld, the lower surface of the weld and the bottom of the weld. Compared with oxidation protective film, the color of heat recovery is thinner and more obvious. The color depends on the thickness and can be seen in rainbow, blue, purple to light yellow and brown. Thicker oxides are usually black. This is caused by staying at high temperature or higher altitude for a long time. When the oxide layer appears, the chromium content on the metal surface will be reduced, resulting in the reduction of corrosion resistance in these areas. In this case, not only should the heat recovery color and other oxide layers be removed, but also the chromium poor metal layer below them should be cleaned.

6、粗磨加工

6. Rough grinding

磨削和机加工会导致表面粗糙，留下凹槽、重叠和毛刺等缺陷。每个缺陷也可能会将金属表面损坏到一定深度，因此不可能通过酸洗、电解抛光或喷丸清理受损的金属表面。粗糙表面可能是腐蚀和沉积产物的来源。在重新焊接之前，不允许使用粗磨清理焊接缺陷或去除多余的焊接钢筋。在后一种情况下，应使用细磨料研磨。

Grinding and machining can lead to rough surfaces, leaving defects such as grooves, overlaps, and burrs. Each defect may also damage the metal surface to a certain depth, so it is impossible to clean the damaged metal surface by pickling, electropolishing or shot peening. Rough surfaces may be the source of corrosion and deposition products. Before re welding, it is not allowed to use rough grinding to clean up welding defects or remove excess welding reinforcement. In the latter case, fine abrasive grinding should be used.
