When selecting colored aluminum coils, one should consider the natural environment, application environment, design period, and structural characteristics of the building to choose the steel type, specifications, coating, and coating that match it.
Among them, wind resistance, impact resistance, snow resistance, earthquake resistance, etc. are all related to the mechanical properties of the data, and of course, they are also related to the waveform, thickness, span, and spacing of the colored profiled steel plate. If a suitable colored aluminum coil is selected and matched with a suitable profiled steel plate design, it can not only meet the safety factor of the building but also reduce the engineering cost. The durability, processing performance, and appearance persistence of the data are largely determined by the durability of the coating and coating.
彩鋁卷表面有一層涂層,涂層就是起到一個重要的作用“防腐蝕”。咱們來講講這個防腐蝕是怎么整理上去的。
The surface of the colored aluminum coil has a layer of coating, which plays an important role in preventing corrosion. Let's talk about how this corrosion protection is organized.
Brushing can use various coatings, as long as it is not a coating with poor leveling ability. This step mainly aims to allow the coating to penetrate into the fine holes on the metal surface, which can enhance the metal adhesion.
In this step, it is necessary to have a higher requirement to use coatings with high liquid purity and viscosity, and to address common defects such as cracking, peeling, and flipping in the coatings.

浸涂是一種傳統(tǒng)的涂裝方法,容易造成空氣污染,千萬要記不要用揮發(fā)性涂料。
Dip coating is a traditional coating method that can easily cause air pollution. Remember not to use volatile coatings.
Spray coating is the process of applying paint onto the surface of a coating. Although it is easy to operate and has high production efficiency, spray coating consumes more than immersion coating, which can cause safety and immersion issues. It is important to pay attention to this.
Spray painting has the advantages of uniform thickness, smooth appearance, and high production efficiency, as well as significant air pollution. The surface of the colored aluminum coil has a layer of coating, which plays an important role in preventing corrosion.
