Qualified aluminum veneers need to undergo multiple tests. This article discusses the specific testing items for aluminum veneers. What are the testing items for aluminum veneers?
The testing items for aluminum veneer generally include appearance quality, film thickness, gloss deviation, adhesion, pencil hardness, hydrochloric acid resistance, nitric acid resistance, mortar resistance, solvent resistance, wear resistance, impact resistance, etc.
What are the specific requirements for the standards of aluminum veneer testing projects? The inspection standard for appearance quality requires that the edges of the board should be cut flush, without burrs or cracks. No welding is allowed on the board. The appearance should be neat, the color should be basically consistent, and there should be no obvious scratches. The decorative surface must not have obvious indentations, imprints, bumps or other residues. No obvious color difference. The coating should be free of flow marks, cracks, bubbles, inclusions, or other surface defects.
Inspection standards for film thickness: average film thickness ≥ 40 μ m, minimum local film thickness ≥ 34 microns
There are three testing items for adhesion: dry, wet, and boiling water boiling.
Pencil hardness should reach at least 1H,
No changes are required during the tests of hydrochloric acid resistance, nitric acid resistance, mortar resistance, and solvent resistance.
The wear resistance should reach 5L ≥/μ m,
The requirement for impact resistance is that the front and back aluminum materials should have no cracks, and the coating should have no peeling or cracking
