1、不允許嚴重的漏涂、涂層脫落、混色、粘連。不允許涂層因烘烤過量發脆變黃、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、不允許存在明顯的色差或光澤不均勻等。

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

3、不允許有明顯的氣孔、氣泡、堆流和起皺現象。

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

4、不允許表面存在麻點、雜質、刮痕、污濁及涂膜不勻。

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

彩涂鋁板是鋁基板經過彩色涂層機組后，在表面涂敷上多層有機涂料并經烘烤固化而成的復合材料。

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.

鋁合金鋁板的表面進行著色處理，因鋁合金鋁板性能十分穩定，不易被腐蝕，一般表層經特殊處理后可以保證至少8年不褪色，更因其密度小、硬度高，單位體積的重量是金屬材料中Z輕的。

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.

彩涂鋁板兼有鋁板與有機材料兩者的優點，既具有鋁板的機械強度高、韌性好、易加工成型等性能優點，又具有有機聚合物涂層材料良好的著色、裝飾性、耐腐性，能很容易地進行沖裁、彎曲、深沖、焊接等加工，制成的產品實用、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.

彩涂鋁板在國外早已廣泛應用，而隨著我國經濟建設的持續高速增長，近十年來，國內彩涂鋁板應用領域和需求不斷擴大。因其使用廣泛、加工簡便、使用年限長、質輕(比重是鐵板的1/3)、單位造價低、涂層保潔防污、色彩豐富艷麗、綠色環保等特點而逐漸成為彩涂板行業的未來發展方向，市場需求量較大。

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.
