确选择彩铝卷应思索建筑物所处的自然环境、运用环境、设计年限、构造特性，来选择与之相匹配的钢种、规格、镀层及涂层等。

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.

建筑师、工程业主及加工方思索的是建筑物的平安性能(耐冲击、抗震、防火、抗风压、抗雪)、寓居性能(防水、隔音、隔热)、耐久性能(耐污染、耐久、外观坚持性)、经济性(本钱低、易加工、易维护、易改换)等。对彩铝卷厂家来说，这些性能作为彩铝卷厂应转化为彩铝卷性能 ，并予以保证。彩铝卷的性能请求主要有力学性能(抗拉强度、屈从强度、延伸率)、镀层性能(镀层品种、镀层厚度和镀层附着力)和涂层性能(涂料种类、颜色、光泽、耐久性能、加工性等)。

Architects, project owners, and processors consider the safety performance (impact resistance, earthquake resistance, fire resistance, wind pressure resistance, snow resistance), residential performance (waterproof, sound insulation, insulation), durability (pollution resistance, durability, appearance persistence), and economy (low cost, easy processing, easy maintenance, and easy replacement) of buildings. For color aluminum coil manufacturers, these properties should be transformed into color aluminum coil performance and guaranteed. The performance requirements of colored aluminum coils mainly include mechanical properties (tensile strength, flexural strength, elongation), coating properties (coating type, coating thickness, and coating adhesion), and coating properties (coating type, color, gloss, durability, processability, etc.).

其中抗风、抗冲击、抗雪、抗震等都和资料的力学性能有关，当然也和彩色压型钢板的波形、钢板的厚度、跨度、檩距有关，假如选择适宜的彩铝卷再配适宜当的压型钢板设计，既能满足建筑物的平安系数又能降低工程造价。而资料的耐久性、加工性能及外观坚持性则大局部由涂层和镀层的耐久性决议。

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.

彩铝卷表面有一层涂层，涂层就是起到一个重要的作用“防腐蚀”。咱们来讲讲这个防腐蚀是怎么整理上去的。

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.

(1)刷涂

(1) Brush coating

刷涂可以使用各种涂料，只要不是流平性较差的涂料就行，这一步骤主要起到让涂料能渗到金属表面的细孔里，能加强的金属附着性。

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.

(2)刮涂

(2) Scraping coating

这一步，要求要高点，用液体纯度高、黏度要高的涂料，注要起到涂料的常见缺陷(开裂、脱落、翻卷等)问题。

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.

(3)浸涂

(3) Dipping coating

浸涂是一种传统的涂装方法，容易造成空气污染，千万要记不要用挥发性涂料。

Dip coating is a traditional coating method that can easily cause air pollution. Remember not to use volatile coatings.

(4)淋涂

(4) Drenched coating

淋涂是将涂料淋到涂物的表面，虽然操作简便、生产效率高，淋涂比浸涂的消耗量大，会产生安全和浸染的问题，一定要注意。

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.

(5)喷涂

(5) Spray coating

喷涂有优点是(涂的厚度均匀、外观也平整、生产效率高)，空气染污也不小。  彩铝卷表面有一层涂层，涂层就是起到一个重要的作用“防腐蚀”。

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.
