The size of the aluminum composite panel is generally. The thickness and length of the aluminum composite panel can be adjusted according to the actual use area. The standard width is 1220. The entire panel can be ordered with a certain amount of other widths is 1220X2440. The size can be cut at will.
Aluminum composite panels can be roughly divided into interior panels and exterior panels.
Generally, the specifications of aluminum composite panels for interior decoration are about 1.22m*2.44m*3mm, and the thickness of the exterior is about 4mm, and the size is variable.
Standard specification of aluminum composite panel: 1220*2440*4mm/3mm. The thicker the aluminum skin, the better the quality and the more expensive. Other sizes can be negotiated with the manufacturer according to requirements.
Aluminum composite panels specification measurement
Thickness: Use a thickness measuring instrument with a minimum graduation of 0.01mm to measure the thickness at least 20mm from the edge of the board. These measuring points should include at least the thickness of the four corners and the midpoint of the four sides.
Take the limit value error between all the measured values and the nominal value as the test result.
Length (width): The length is on both sides of the board width, and the width is measured on both sides of the board length with a steel tape with a minimum graduation of 1mm.
Take the limit value error between all the measured values of length (width) and the nominal value as the test result.
Diagonal difference: use a steel tape with a minimum graduation of 1mm to measure and calculate the difference between the lengths of two diagonals on the same board.
Edge straightness: Lay the board flat on a water platform, use a 1000mm-long steel ruler against the edge of the board, and then use a feeler gauge to measure the maximum gap between the edge of the board and the side of the steel ruler.
Warpage: Lay the concave surface of the board flat on the water platform, use a 1000mm long steel ruler to stand on the top of the board, and then use a ruler with a minimum graduation of 0.5mm to measure the distance between the steel ruler and the board. Maximum gap height.
Take the maximum value among all the measured values as the test result.
Aluminum thickness: The aluminum removed from the sample is used as the test piece. Use a thickness measuring instrument with a minimum graduation of 0.001mm to measure the thickness of the aluminum material (the thickness of the coating should not be included). The measurement should be carried out in enough places, but at least the four corners and the center should be measured on each test piece.
Take the minimum value and arithmetic mean of all measured values as the test result.
Coating thickness: The coating thickness refers to the total thickness of the coating. The test shall be carried out in enough places on the test piece in accordance with the provisions of GB/T4957.
