In real life, many consumers believe that villa copper door products will not rust. I think it's incredible that the copper door is rusty. I suspect it's a fake copper door. In fact, iron door rust is rust, while copper door rust is copper rust. So why are the copper doors of Chinese villas rusty?

一、当消费者家中的铜门不小心被刮伤表面的金属保护漆后，时间一长，里面的铜接触到空气后，会产生铜绿，俗称“铜锈”。倘若铜门生了锈，势必会影响铜门的美观。

1、 When the copper door in the consumer's home is accidentally scratched by the metal protective paint on the surface, after a long time, the copper inside will produce copper green after contacting the air, commonly known as "copper rust". If the copper door rusts, it is bound to affect the beauty of the copper door.

二、铜门表面会有斑的原因可能是应为漆在表面的油漆质量有问题，或者是在喷漆时，操作步骤不恰当导致颜色不均匀。这是原因之一，所以在制作铜门的时候，不能为了节省成本有的部分喷漆的量不够，很容易使铜门掉漆。

2、 The reason is that the paint on the door surface is not uniform, or there may be paint spots on the door surface. This is one of the reasons, so when making copper doors, we can't save costs. Some parts of the paint is not enough, which is easy to make the paint fall off.

三、在制作铜门的过程中，门框经常是没有干透就喷漆，时间长了门框一定会上绣的。这其实在很多的别墅铜门生产厂都能够看的到，很多时候是为了节约时间，没有经过烤制。其实如果是经过烤箱，温度把握不准的话，铜门表面会发黄的。少一点客户的投诉，能增加一些业绩，在市场上的竞争会占优势的。

3、 In the process of making a copper door, the door frame is often painted without drying. The door frame will be embroidered after a long time. In fact, this can be seen in many villa copper door production plants. Most of the time, it is to save time without baking. In fact, if it is through the oven and the temperature is not sure, the surface of the copper door will turn yellow. Less customer complaints can increase some performance and gain an advantage in the market competition.

四、铜门还会经过化学药水的处理，处理之后一定要将化学药剂清洗干净，不然时间以长会生出黑色的锈斑。

4、 The copper door will also be treated with chemical liquid. After treatment, the chemical must be cleaned, otherwise black rust will appear over time.

五、很多的厂家在制造铜门的过程中为了省下那几百块钱偷工减料，去、其后引来的是顾客的投诉，这又是何苦呢。铜门生锈之后还要派人过去修理，这将会花掉一部分钱，算是按照一平方米几百块钱来算的话，制作铜门的成本实际上是多花了几千块钱。可能因为生锈的事将会失去很多的潜在客户，这才是大的损失。

5、 In the process of manufacturing copper doors, in order to save hundreds of dollars, many manufacturers cut corners on work and materials, and then attracted complaints from customers. Why bother. After the copper door rusts, someone has to be sent to repair it, which will cost a penny. If it is calculated according to hundreds of yuan per square meter, the cost of making the copper door is actually thousands of yuan more. Maybe you will lose a lot of potential customers because of rust, which is a big loss.

除锈的方法？

How to remove rust?

一、浸泡除锈

1、 Immersion derusting

铜生锈的时间较长时，里面会包含一层土锈，这种土锈用常规的方法是很难洗掉的。所以需要用烤漆门毛巾敷在生锈的铜门上，再用细软的小刷子刷洗即可。注意，此过程带隔热手套，防止手被开水烫着，如果一次洗不掉铜锈，那反复浸泡几次即可。

When copper rusts for a long time, it will contain a layer of soil rust, which is difficult to wash off by conventional methods. Therefore, you need to apply a paint door towel on the rusty copper door and then brush it with a small soft brush. Note: wear insulating gloves during this process to prevent your hands from being scalded by boiling water. If you can't wash off the copper rust at one time, soak it repeatedly for several times.

二、干刷除锈

2、 Dry brush derusting

铜门虽然抗腐蚀性较好，但长期不进行铜门保养的话，几年下来，还是会有一层浅浅的铜锈的。遇到此种较浅的铜锈时，防盗门可以用一支大号的毛笔或者细软的油漆刷来干刷除锈。刷洗的过程用力要均匀，刷完后用清水洗净，再用毛巾擦干即可。

Although the copper door has good corrosion resistance, if the copper door is not maintained for a long time, there will still be a layer of shallow copper rust in a few years. In case of such shallow copper rust, the anti-theft door can be dry brushed with a large brush or a soft paint brush. The brushing process should be forced evenly. After brushing, wash it with clean water and then dry it with a towel.

三、刀刮除锈

3、 Rust removal by knife scraping

如果铜锈较顽固，用毛刷是刷不掉的，可以用小刀来刮掉铜锈。难度较大，稍有不慎，很容易刮伤铜门表皮。所以，请不要试用。方法也很简单，把毛刷换成小刀对准铜锈轻轻的刮即可，速度一定要慢，用力轻柔并循序渐进。

If the copper rust is stubborn and cannot be brushed off with a brush, you can scrape it off with a knife. It's very difficult. If you are careless, it's easy to scratch the surface of the copper door. So please don't try. The method is also very simple. Replace the brush with a knife and gently scrape the copper rust. The speed must be slow, gentle and step by step.

四、醋泡除锈

4、 Rust removal with vinegar

如果铜门上的铜锈痕迹较深，那可用醋泡法来除锈。铜绿是碱性的，通过酸性的醋进行中和反应之后，能很好的去除铜绿。取一个小碗，倒入半碗食醋，再用清水将铜门的生锈部位洗净，然后用毛巾蘸取食醋后敷在铜锈上。待到20小时后，用毛刷刷去掉下的残锈，不锈钢门再用清水洗净铜门生锈部位后擦干即可。如果以上方法都不能除掉您铜门上的顽固铜锈，那只能请铜门厂帮忙了。叫铜门厂拆下铜门后回厂重新喷漆，方能让铜门恢复光彩，此法也无需太多钱。所以，平常对铜门稍加保养还是很有必要的，至少可以大大延长铜门的寿命和美观性。

If the copper rust trace on the copper door is deep, the vinegar bubble method can be used to remove the rust. Aeruginosa is alkaline. It can be well removed after neutralization reaction with acidic vinegar. Take a small bowl, pour in half a bowl of vinegar, then wash the rusty part of the copper door with clean water, and then dip the vinegar with a towel and apply it on the copper rust. After 20 hours, remove the remaining rust with a brush, clean the stainless steel door with clean water, and wipe dry the rusty part of the copper door. If none of the above methods can remove the stubborn copper rust on your copper door, you can only ask the copper door factory for help. Ask the copper door factory to dismantle the copper door and return to the factory for repainting, so as to restore the luster of the copper door. This method does not need too much money. Therefore, it is necessary to maintain the copper door slightly, which can at least greatly prolong the service life and beauty of the copper door.
