First of all, we should know the reason for the paint falling off of the copper door: the paint selected by the formal new Chinese copper door manufacturers is a professional baking paint specially used for the copper door. Copper door paint can make the surface of copper plate smooth and bright, uniform color, beautiful and transparent color. This kind of copper door paint is difficult to fall off during use. To achieve this effect, you need to pay attention to some details in the oxidation process:

1.烘烤温度和时间，根据客户选择的颜色深浅定制烘烤时间和温度。

1. Baking temperature and time. The baking time and temperature are customized according to the color depth selected by the customer.

2.使用铜门专用漆。

2. Use special paint for copper door.

3.氧化

3. Oxidation

此外，新中式铜门在使用过程中，有铜门掉漆现象，或不慎被利器划伤。不得私自填充其他油漆或其他油漆修补方法。建议您找的铜门厂家帮您解决。铜门的日常破损修复性相对较好，可以通过打磨、打磨、塑形、油漆等方式进行修复。但是一旦出现凹陷现象，修复铜门是很困难的工作，

In addition, during the use of the new Chinese style copper door, the paint of the copper door fell off or was scratched by sharp tools. Do not fill other paints or other paint repair methods without permission. I suggest you find a professional copper door manufacturer to help you solve it. The daily damage repair of copper doors is relatively good, which can be repaired by grinding, grinding, shaping, painting and other methods. However, once there is a depression, it is difficult to repair the copper door, so how to repair the sunken copper door

用真空机的负压将凹陷吸上来,真空机的负压吸起凹陷。这种方法只适用于薄钣金的铜门，如果钣金较厚则不适用,较厚的铜板可用高强磁铁吸

Suck up the depression with the negative pressure of the vacuum machine, and the negative pressure of the vacuum machine sucks up the depression. This method is only applicable to the copper door with thin sheet metal. If the sheet metal is thick, it is not applicable. The thicker copper plate can be absorbed by high-strength magnet

用高强度磁铁吸上来，因为同一扇门中间是空的，可以在门中空部分放置钕铁硼强磁铁，用弱磁性的导线引导外部，使强磁铁到达凹陷部分，再用高强度电磁铁吸引外部，可将厚度约1毫米的铜板凹陷抬起。如果厚度较高，则应使用第三种方法。

Use a high-strength magnet to suck it up. Because the middle of the same door is empty, you can place a Nd-Fe-B strong magnet in the hollow part of the door, guide the outside with a weak magnetic wire to make the strong magnet reach the concave part, and then use a high-strength electromagnet to attract the outside to lift the copper plate concave with a thickness of about 1mm. If the thickness is high, the third method should be used.

用液压进行强力牵引在铜门凹陷处焊接多根铜支作为着力点，利用液压或换轮组强力牵引，可将铜板凹陷处提起。

Use hydraulic pressure for strong traction, weld multiple copper branches at the copper door depression as the force point, and use hydraulic pressure or wheel change group for strong traction to lift the copper plate depression.

将修复的凹陷打磨平整,用砂轮将修复后的凹陷打磨平整，有弧线或棱角的位置要与门体整体形象统一。如有焊接铜枝，应先将铜枝打磨掉，再进一步打磨平整。

The repaired depression shall be polished and leveled, and the repaired depression shall be polished and leveled with a grinding wheel. The positions with arcs or edges and corners shall be consistent with the overall image of the door body. If there are welded copper branches, the copper branches shall be polished off first, and then further polished and leveled.

作色确保整个铜门颜色统一,新中式铜门制作时的着色，采用蚀刻液制色，保证整扇铜门颜色均匀。之后一步是喷漆保护,使用同名或同色铜门保护漆进行油漆保护，到此，整个铜门凹陷修复完毕

The color shall be made to ensure the uniform color of the whole copper door. The color of the new Chinese copper door shall be made with etching solution to ensure the uniform color of the whole copper door. The next step is painting protection. The copper door protective paint with the same name or color is used for paint protection. At this point, the whole copper door depression is repaired
