1、不允许严重的漏涂、涂层脱落、混色、粘连。不允许涂层因烘烤过量发脆变黄、失光等。

1. Serious holidays, coating peeling, color mixing, and adhesion are not allowed. It is not allowed for the coating to become brittle, yellow, or lose luster due to excessive baking.

2、不允许存在明显的色差或光泽不均匀等。

2. No obvious color difference or uneven gloss is allowed.

3、不允许有明显的气孔、气泡、堆流和起皱现象。

3. No obvious pores, bubbles, flow accumulation, or wrinkling are allowed.

4、不允许表面存在麻点、杂质、刮痕、污浊及涂膜不匀。

4. No surface spots, impurities, scratches, stains, or uneven coating are allowed.

彩涂铝板是铝基板经过彩色涂层机组后，在表面涂敷上多层有机涂料并经烘烤固化而成的复合材料。

Color coated aluminum plate is a composite material formed by applying multiple layers of organic coatings on the surface of an aluminum substrate after undergoing a color coating unit and baking curing.

铝合金铝板的表面进行着色处理，因铝合金铝板性能十分稳定，不易被腐蚀，一般表层经特殊处理后可以保证至少8年不褪色，更因其密度小、硬度高，单位体积的重量是金属材料中Z轻的。

The surface of aluminum alloy aluminum plate undergoes coloring treatment. Due to the stable performance of aluminum alloy aluminum plate, it is not easily corroded. Generally, the surface can be guaranteed to not fade for at least 8 years after special treatment. Moreover, due to its low density and high hardness, the weight per unit volume is lighter than that of metallic materials.

彩涂铝板兼有铝板与有机材料两者的优点，既具有铝板的机械强度高、韧性好、易加工成型等性能优点，又具有有机聚合物涂层材料良好的着色、装饰性、耐腐性，能很容易地进行冲裁、弯曲、深冲、焊接等加工，制成的产品实用、易加工、耐久。

Colored aluminum sheet combines the advantages of both aluminum sheet and organic materials. It has the advantages of high mechanical strength, good toughness, and easy processing and forming of aluminum sheet, as well as the good coloring, decoration, and corrosion resistance of organic polymer coating materials. It can be easily processed by punching, bending, deep drawing, welding, and other processes, resulting in practical, easy to process, and durable products.

彩涂铝板在国外早已广泛应用，而随着我国经济建设的持续高速增长，近十年来，国内彩涂铝板应用领域和需求不断扩大。因其使用广泛、加工简便、使用年限长、质轻(比重是铁板的1/3)、单位造价低、涂层保洁防污、色彩丰富艳丽、绿色环保等特点而逐渐成为彩涂板行业的未来发展方向，市场需求量较大。

Color coated aluminum panels have long been widely used abroad, and with the sustained high-speed growth of China's economic construction, the application field and demand for color coated aluminum panels in China have been continuously expanding in the past decade. Due to its wide use, simple processing, long service life, light weight (accounting for one-third of iron plate), low unit cost, coating cleaning and anti fouling, rich and vibrant colors, and green environmental protection, it has gradually become the future development direction of the color coated board industry, with a large market demand.
