Color coated embossed aluminum sheet production steps

Color coated embossed aluminum sheet, made by the method comprising the steps of:
1) The aluminum unwinding, through the shaft into the degreasing tank degreasing degreasing, degreasing agent for the aluminum off, degreasing at room temperature for 1 minute.
2) into the cleaning tank for cleaning, cleaning temperature is 20 ℃, cleaning time is 10 seconds, cleaning tank PH value controlled at 7.
3) passivation passivation passivation passivation, passivation at room temperature for 10 seconds, the primer coated on the passivation layer, and then into the oven drying, drying temperature of 100 ℃;
4) into the coating roller coating polyester coating, and then into the oven drying oven temperature of 260 ° C, drying time of 60 seconds;
5) Through the inspection, winding, unwinding embossed into the embossed, and finally winding the finished product.

Color coated embossed aluminum sheet testing technology standards are as follows:
Coating thickness: ≥ 18um;
Pencil hardness: ≥ 2H (ordinary embossed aluminum is 1H);
Adhesion: not inferior to level 1
Flexibility: ≤ 2T (ordinary embossed aluminum 3T)
Gloss: gloss <70, the limit error ≤ 10%, gloss ≥ 70, the limit error ≤ 5%;
Resistance to boiling water: 2 hours no change (ordinary embossed aluminum 1 hour change)
