When we buy a product from an aluminium composite panel manufacturer,
we must check its quality, mainly by using which methods?
You can visually observe the flatness of the board surface, whether warping and deformation,
and whether the board is square and square, the logo such as certificate of conformity, protective film, etc. is fine.
Then it is a matter of feeling the board with your hands, pulling up the corners to feel the strength, toughness and elasticity of the board.
For the aluminium thickness and core material, you can use a blade to lightly scrape the edge of the board, if the board is too soft,
its aluminium thickness must be thin, there is also the use of nails in the edge of the board to scrape whether there are marks, etc.,
can have an understanding of the aluminium thickness they need.
Usually in the cleaning of aluminium composite panels,
the use of corrosive cleaning agents, but also to cause the colour of aluminium composite panels dis-colouration,
fading, this also need to pay attention to.
