Door is an important barrier to protect the interior and human body in our life, and copper door is a kind of door popular with consumers in our life. Therefore, there are many imitation copper doors on the market, but when we use them, we find that imitation copper doors are very easy to fade and fall off paint. What is the reason?

铜门厂家说说为什么仿铜门容易褪色掉漆的原因

Copper door manufacturers talk about why imitation copper doors are easy to fade and lose paint

主要是因为耐侯性的问题没去解决。根据目前仿铜门的表面处理工艺主要是以“转印”“金属漆”“塑粉直接着色”等及少数特殊工艺组成。我们分别予以一一分析及解决。转印工艺的“易褪色、掉漆”  目前，转印工艺的普遍流程都是：聚醚型环氧塑粉底→烤干→转印→撕纸、打磨→除尘→罩光→烤干，其易褪色、掉漆在室外出现较多，为什么在室外容易出现这些问题呢?因为在室外是自然条件下曝晒或被风霜雨雪浸蚀，所以要求我们在用材上要有针对性：

The main reason is that the problem of weather resistance has not been solved. At present, the surface treatment process of imitation copper door is mainly composed of "transfer printing", "metallic paint", "direct coloring of plastic powder" and a few special processes. We analyze and solve them one by one. Transfer printing process is "faded and lacquer". The general process of transfer printing is: polyether epoxy plastic foundation make-up, drying, transfer printing, tear, paper, grinding, dust removing, covering, light drying, and it is easy to fade and paint out. There are many problems in outdoor. What are the problems that are likely to arise in outdoor? Because it is exposed to the sun or eroded by wind, frost, rain and snow under natural conditions outdoors, we are required to be targeted in the use of materials:

1.聚醚型环氧塑粉的特性是成本低，好转印好撕纸，但在见光的情况下会很快粉化;

1. Polyether epoxy plastic powder has the characteristics of low cost, good transfer printing and paper tearing, but it will be powdered quickly in the presence of light;

2.转印纸是在以纸作为载体，用油墨印刷上去，再通过其易迁移的特点在一定温度下转印到塑粉底上面，其油墨的好坏直接关系到花纹的褪色快慢速度;

2. transfer paper is printed on ink as paper carrier, and then transferred to plastic foundation make-up at a certain temperature through its ink transfer characteristics. Its ink quality is directly related to the fading speed and speed of pattern.

3.罩光油起到美观、增加手感及附加价值和保护的作用，但现今钢木门面上使用的普通光油没有耐紫外线功能。

3. The cover varnish plays the role of beauty, increasing hand feel, added value and protection, but the ordinary varnish used on steel and wood doors nowadays has no UV resistance function.
