金属幕墙，是一种新型的建筑幕墙形式，用于外墙装修。金属幕墙作为以金属板材为墙面材料的建筑幕墙，是将玻璃更换为金属板材的一种幕墙形式。由于金属板材有着优良的加工性能，多样丰富的色彩以及良好的安全性，能十分完美的适应各种复杂造型的设计，可以任意增加凹进和凸出的线条，而且可以加工各种型式的曲线线条，让建筑师有很大的发展空间，所以倍受建筑师的青睐，因此被广泛的应用于建筑设计中。

Metal curtain wall, is a new type of building curtain wall form, used for exterior wall decoration.Metal curtain wall, as a building curtain wall with metal plate as the wall material, is a curtain wall form of replacing glass with metal plate.Because sheet metal has excellent processing performance, diverse rich color and good safety, can perfectly adapt to all kinds of complex modelling design, can increase concave and convex lines, and can process a variety of types of curve line, let the architect has a great development space, so favored by architects, so is widely used in architectural design.

金属幕墙使用的面材很多，例如铝复合板，单层铝板，防火板等，目前在金属幕墙大多都是铝板幕墙材质的，一般使用最多的还是铝复合板，单层铝板，和夹芯保温等三种材质。

Metal curtain wall uses a lot of surface materials, such as aluminum composite plate, single-layer aluminum plate, fire board, etc., currently in the metal curtain wall is mostly aluminum plate curtain wall material, generally use the most or aluminum composite plate, single-layer aluminum plate, and sandwich insulation and other three materials.

单层铝板是采用2.5mm或3mm厚铝合金板，外幕墙用单层铝板表面与铝复合板正面涂膜材料一致，膜层坚韧性、稳定性，附着力和耐久性完全一致。单层铝板是继铝复合板之后的又一种金属幕墙常用面板材料，而且应用得越来越多。

Single layer aluminum plate is made of 2.5mm or 3mm thick aluminum alloy plate. The surface of single layer aluminum plate is consistent with the front of aluminum composite plate. The film layer toughness, stability, adhesion and durability are exactly the same.Single-layer aluminum plate is another common panel material of metal curtain wall after aluminum composite plate, and it is more and more used.

铝材表面可作各种涂层的处理(其他金属材料也可)，涂层的目的一般为保护金属材料、提高耐久性、形成设计师所需要的色彩及图案等。各种涂漆都是由有机塑料、溶剂和色母料等根据一定的配方混合形成的，它在室外气候条件下都会逐渐老化，表现为褪色、粉化、开裂、起皮等现象。不同涂漆的性能差异主要表现在耐候性上，即在自然的太阳紫外线、风雨、污染等侵蚀下的表现。常用的涂漆方法有电泳涂漆、静电粉末喷涂、氟碳喷涂等。

Aluminum surface can be treated as various coatings (other metal materials can also be), the purpose of the coating is generally to protect the metal materials, improve the durability, and form the colors and patterns needed by the designer.All kinds of paint are formed by organic plastic, solvent and color mother material according to a certain formula, it will gradually aging under outdoor climate conditions, manifested as fading, powder, cracking, peeling and other phenomena.The performance difference of different paint is mainly manifested in the weather resistance, that is, in the natural solar ultraviolet light, wind and rain, pollution and other erosion performance.Commonly used painting methods are electrophoretic painting, electrostatic powder spraying, fluorocarbon spraying, etc.
