Color-coated aluminum sheets are one of the important products of aluminum processing enterprises. Because of their light weight, bending resistance, and corrosion resistance, they are widely used in various fields, such as electronic equipment, architectural decoration, interior decoration, etc. Color-coated aluminum sheets are long-lasting and durable. After special The processed color-coated aluminum plates can even have a long-term warranty of 20 or 30 years. The many advantages of color-coated aluminum are inseparable from its special production process.

The paint layer of color-coated aluminum plates is divided into two categories: roller coating and spray coating. This process is a key procedure for quality assurance of color aluminum products. Roller coating refers to the continuous and uninterrupted degreasing, chemical pretreatment and color coating of the aluminum substrate.

The roller primer is the coating between the top coat and the aluminum plate, which enhances the bonding strength between the top coat and the aluminum plate; the back coating is the anti-corrosion coating on the back of the aluminum plate, which enhances the anti-corrosion ability of the color-coated plate.

Roller coating is a two-time baking process, and spray coating is a one-time baking process.

Color-coated aluminum strips are aluminum and aluminum alloy strips whose surface has been coated and colored. They are deep-processed products of aluminum and aluminum alloy strips. Because it has good flatness, corrosion resistance, decoration and mechanical properties, it is favored by the market and is widely used in architectural decoration, food packaging, electronic appliances, printing, transportation and other fields. Color-coated aluminum is divided into high-end fluorocarbon color coating and mid-to-low-end polyester color coating. my country's Guangdong, Jiangsu, Shanghai, and Shandong are key markets for the color-coated aluminum industry. The current situation of color-coated aluminum in my country is that there is excess production capacity for ordinary products and insufficient production capacity for high-tech, high-precision, and high-quality products, which has also resulted in the emergence of large-scale imports.
