Serious peeling, color mixing, and adhesion of the missed coating are not allowed. It is not allowed for the coating to become brittle, yellow, or dull due to excessive baking.

不允许存在明显的色差或光泽不均匀等。

No obvious color difference or uneven gloss is allowed.

不允许有明显的气孔气泡堆流和起皱现象。

It is not allowed to have obvious air holes, bubble accumulation, and wrinkling.

不允许表面存在麻点杂质刮痕污浊及涂膜不匀。

It is not allowed to have pits, impurities, scratches, stains, or uneven coating on the surface.

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 made by applying multiple layers of organic coatings on the surface of an aluminum substrate after undergoing a color coating unit and curing through baking.

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 is subjected to coloring treatment. Due to its very stable performance and resistance to corrosion, the surface can generally 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 has the advantages of both aluminum sheet and organic material. It not only has the mechanical strength, high toughness, and easy processing and forming properties of aluminum sheet, but also has the good coloring and decoration properties of organic polymer coating materials, corrosion resistance, and can be easily processed for punching, bending, deep drawing, welding, and other processing. The product made is practical, easy to process, and durable.

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 been widely used abroad, and with the sustained and rapid 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 widespread use, easy processing, long lifespan, and light weight (accounting for 1/3 of iron plate), low unit cost, coating, cleaning, anti fouling, rich and colorful green environmental protection, it has gradually become the future development direction of the color coated board industry, with a large market demand.
