How to inspect the quality of aluminum veneer

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

The grade, condition, specifications, and thickness grade of aluminum veneer can be determined through elemental analysis of the material. Hardness can be tested for elasticity. The thickness can be measured with a caliper. The hardness and stretchability of aluminum veneer are checked. Currently, there are products on the market that use aluminum slag as a substitute for aluminum material.

The hardness and stretchability of aluminum slag are far inferior to good aluminum materials. Oil contamination inspection can be conducted on aluminum veneer after cleaning and before spraying. Check if there are any oil stains on the aluminum veneer and if it affects the spraying quality, especially for aluminum veneers that require grooving. There is a lot of lubricating oil during the grooving process.

The specific method is as follows: contact the surface of the aluminum veneer with an alkaline chemical formula, observe its continuity, continuity indicates cleanliness, and vice versa indicates insufficient cleanliness. Check the adhesion between paint and aluminum veneer to see if the paint is adhered to the aluminum veneer or if it is a false adhesive. Using boiling water method, boil the aluminum veneer coated with paint in boiling water to see if the paint bubbles or peels off. If there is foaming or peeling, it indicates that the adhesion has not yet reached the required level.
