    Quality of Complex Film
    Rank Anode oxide film Paint film Complex film Paint the membrane Appearance quality
    Average film thickness Local film thickness Local film thickness Local film thickness Adhesive force Hardness Before applying paint, the appearance quality of the sectional material should accord with the relevant regulations of GB. The finished paint film should be even and neat, and it is not allowed to have such defects as wrinkle , crackles, bubbles, flowing marks, inclusions , sticking and coming off of paint film, etc, which influences the use, but in the 8m range of an end of the electrophoresis sectional material , it is allowed to have no paint film locally.

    Coating Performance
    Thickness of the coating(μm) Color and color difference Indentation hardness (Print resistance) Adhesive force Impact resistance cup-drawing test Appearance quality
    Average thickness Maximum local thickness Minimum local thickness
    ≥60 ≥120 ≥40 The color of the coating should be the same as the standard color that the contract stipulates ≥80 0 grade The front of the coating, after an impact test, has no phenomenon of fracture and coming off, but it is allowed to have small wrinkles in the perimeter of a concave surface. After a cup-drawing test with of the indentation depth of 6mm, there should not be the phenomena of splitting and coming off on the coating The coating of a decorative surface of the powder-sprayed sectional material should be smooth and even, and it is not allowed to have such defects as flowing marks, swelling bubbles, crackles, sticking, etc, which influence the use. It is allowed to have a slight tangerine peel phenomenon, and the degree that is allowed should be indicated by a guide sample of a material object which both the supplying and demanding sides have agreed on.
