Shandong copper door manufacturers and you to talk about, if we want to make iron door imitation brass door, we step is to remove the rust on the top, after coating a layer of rust paint, the brass gold powder is painted. When it's dry, brush the door with a black matte paint brush, but don't paint suoy black. It's too regular. This is a common copper imitation method, manufacturers have the ability to operate. The current copper door manufacturers generally use acid pickling and phosphating process before coating the stolen door. Because the structure of the stolen copper door is often complex, it is usually welded with hot rolled pipe, hot rolled plate, forging and cold plate, etc., so it is difficult to spray it. Therefore, oil removal and rust removal before painting are all copper time If this step is not done well, the paint on the top will fall off after a period of time, and the beauty of the copper door will be affected.

1、醋泡法。将生锈的铜洗净，置于一小碟中，倒入少许食用醋，直浸没。过24小时后取出，用小刷子刷去残锈，再用清水洗醋液，擦净阴干j可。

1. Vinegar bubble method. Wash the rusty copper and place in a small dish. Pour in a little vinegar until immersed. After 24 hours, remove the rust with a small brush, and then wash the vinegar with water, wipe clean and dry in the shade.

2、开水浸泡法。生锈的铜有时覆盖一层洗不掉的土锈，这时可先将生锈的铜放入碗中，然后倒入温度为80℃90℃的开水，直被浸没。5分钟后将其取出，用小刷子刷清，阴干j可。遇到土锈严 的，还可将水加温沸腾，使土锈脱落。

2. Boiling water immersion method. Sometimes the rusty copper is covered with a layer of soil rust that cannot be washed off. At this time, the rusty copper can be put into the bowl, and then the boiling water with the temperature of 80 ℃ to 90 ℃ can be poured in until it is immersed. Take it out after 5 minutes, brush it with a small brush, and dry it in the shade. In case of severe soil rust, the water can be heated to boiling to make the soil rust fall off.

3、干刷法。遇铜锈或铁锈附着比较浅时，应尽量bm用醋泡等化学手段，而可改用干刷的方法。具体方法是选大油画笔一枝，将笔头上的棕毛剪离根部0.5-0.7厘米j可使用。先将待刷生锈的铜置于玻璃板上，固定住，油画笔根部均匀地刷，要注意用力，否则不佳，然后再用清水洗净。

3. Dry brush method. In case of copper rust or rust adhesion is relatively shallow, BM should try to use vinegar bubble and other chemical means, but can change to dry brush method. The specific method is to select a large oil painting brush and cut the brown hair on the head to 0.5-0.7 cm J away from the root, which can be used. First place the rusty copper on the glass plate and fix it. Brush the root of the oil brush evenly. Pay attention to the force, otherwise it is not good. Then clean it with water.

4、加热法。这种方法主要是针对锈蚀较浅的铁钱。铁锈的主要成分是氧化亚铁，其结构比较疏松，因此利用热胀冷缩的原理j可使部分铁钱的锈蚀脱落。但运用这一方法时，0须注意加一个承接器皿(如锅等金属容器)，此外好加一些清水。其次是加热时间不宜过长，一般旺火加热三四分钟后，取出用冷湿毛巾捂住，锈便会自然脱落。选择加热法除锈，对象应是铁质尚好且锈蚀比较浅的铁钱，把锈蚀严 且铜体已f常脆弱的铜钱用加热法除锈，否则本已脆弱铜体会耐不住高温而支离破碎，粉身碎骨。

4. Heating method. This method is mainly aimed at iron coin with shallow corrosion. The main component of rust is ferrous oxide, and its structure is relatively loose. Therefore, using the principle of thermal expansion and cold contraction, some iron coins can be rusted off. However, when using this method, 0 should pay attention to add a container (such as metal containers such as pots), in addition to adding some water. Secondly, the heating time should not be too long. After heating for three or four minutes on a high fire, the rust will fall off naturally. Choose heating method to remove rust, the object should be iron coin with good iron quality and relatively shallow corrosion, and use heating method to remove rust for copper coin which is severely rusted and the copper body is often fragile. Otherwise, the already fragile copper will not be able to withstand high temperature and be fragmented.

5、刀刮法。使用此法要注意轻 适度，如果不慎，轻则会把铜刮得遍体鳞， 则整个铜体损坏。因此，如无把握，就别刮。

5. Knife scraping. If not careful, the copper will be scraped all over the body and the whole copper body will be damaged. So if you're not sure, don't scratch.
