First of all, from the flatness, folding and joints of the aluminum veneer surface. The selection of high-quality aluminum veneer is strict in the selection of aluminum raw materials, and there are few impurities. The aluminum veneer will not be deformed after being sprayed at high temperature, and the processing equipment and management of sheet metal processing will affect the flatness of the aluminum veneer;
Aluminum sheet plate is generally 20mm high and the angle is 90 degrees, which can intuitively show the quality of the product. The surface spraying of aluminum veneer, high-quality aluminum veneer uses the top-level aluminum veneer spraying line, no metal and non-metallic debris will infiltrate during the spraying process, the process accuracy is high, and the surface and inner layer feel smooth and comfortable , smooth and without clutter;
The surface of the aluminum veneer is sprayed evenly without color difference, and the coating reaches the international standard. The high-quality aluminum veneer has uniform wall thickness, the aluminum veneer is closely combined, and the quality and thickness of the aluminum veneer can reach the national standard; while the wall thickness deviation of the fake and inferior products is large, the aluminum plate is thin, and the gap between the aluminum veneer materials is large. .
Use a small pressure pump to test the pressure resistance of aluminum veneer materials. The blasting internal pressure of high-quality aluminum veneer is high, which can generally meet or exceed the requirements of relevant national specifications; while the blasting internal pressure of inferior aluminum veneer is generally low, and it is difficult to meet the requirements of use. After judging by the above four methods, the quality of the aluminum veneer can basically be judged.
