The preparation process of the embossed aluminum plate includes the following steps:
(1) Unwind the smooth aluminum sheet through the unwinder, and the speed of the unwinder is controlled at 4 m/min. The convex and concave patterns of the rollers mesh with each other;
(2) The embossed aluminum material is transported into the oxidizing liquid pool through the transmission positioning roller for anodic oxidation. There are multiple transmission positioning rollers in the oxidation liquid tank, which are used for the transmission of the aluminum material. The length of the oxidation liquid tank is 40 meters. The time is 10 minutes, and the temperature of the oxidizing liquid is 30 °C;
(3) The oxidized aluminum plate is sprayed by the upper and lower spray heads with cleaning solution to clean the front and back of the aluminum plate, and the temperature of the cleaning solution is 22 °C;
(4) The cleaned aluminum sheet is baked in an oven, the temperature of the upper oven is controlled at 98°C, the temperature of the lower oven is controlled at 102°C, and the baking time is 36 seconds;
(5) Enter the longitudinal slitting machine through the conveying roller for longitudinal slitting;
(6) The aluminum sheet after longitudinal slitting enters the flattening machine through the conveying roller for leveling. After leveling, it is conveyed into the cross-cutting machine through the conveying roller. The cross-cutting machine performs cross-cutting according to the length of the aluminum sheet to obtain an embossed aluminum sheet .
The preparation process is firstly embossing the whole roll, and then slitting to make the embossed aluminum plate of the required size. The process is simple, the efficiency is high, and the manufacturing cost is saved. Good corrosion resistance. --HWALU Factory
