How to distinguish the quality of aluminum veneer

How to distinguish the quality of aluminum veneer? As a manufacturer of aluminum veneer in Weifang, let me take you to understand how to distinguish the quality of aluminum veneer together!

Aluminum veneer, thickness: According to national standards, the thickness of exterior wall panels should be millimeters, and the thickness of aluminum panels should be millimeters Millimeters; The thickness of the interior wall panel should be millimeters, and the thickness of the aluminum plate should be Millimeters; The aluminum plate of the exterior wall panel is significantly harder than that of the interior wall panel. Peel test: The aluminum plate and core layer should not be easily peeled off, and after peeling, there should be a layer of brushed film on both the aluminum plate and plastic core material. Check the hardness of the paint: Generally, fluorocarbon paint is slightly softer than other paints, and consumers can use hard objects to scratch the surface of the paint, which requires careful consideration.

After boiling, observe: Boil the sample for hours, cool it down, and observe that there should be no glue separation between the aluminum plate and the plastic. According to the method described above, the paint adhesion can be observed by using a sharp knife to draw some millimeter by millimeter squares on the paint surface (the paint film should be drawn through until the aluminum plate), then use adhesive tape paper to stick firmly on the squares and quickly tear them off. The paint film should not fall off. Observing its shape: The size of aluminum veneer should be standardized and neat, with uniform thickness, smooth surface, and straight board shape.

When standing the board on the ground, the product cannot stand. Lift one end of the board and weigh it, and it should not feel too soft. Tear off the protective film on the surface of the product and observe that the paint surface should be clean, without surface defects such as color difference, spots, scars, uneven gloss, and paint leakage. The film should be free from detachment and brittleness. Wipe with solvent: Soak cotton yarn or soft cloth in butanone and gently rub back and forth on the surface of the paint film. The paint film should not be wiped off.

Smell it: Peel off the aluminum plate and there should be no pungent odor of organic solvents. Observe whether there is brittle fracture: When bending the aluminum veneer with force, there should be no obvious brittle fracture of the aluminum veneer. Of course, it is necessary to strictly judge the quality of aluminum veneer, and simple identification alone is not enough. Legitimate manufacturers are also a major guarantee for the quality of aluminum veneer.
