Specifications and dimensions of aluminum-plastic plate
The size of the aluminum-plastic board is generally, the size and length of the aluminum-plastic board can be adjusted according to the actual use area, the standard width is 1220, the other width to order the whole sheet is 1220X2440, the size can be cut at will. Aluminum-plastic panels can be divided into interior panels and exterior panels. General interior with aluminum plastic panel specifications
About 1.22m*2.44m*3mm, the thickness of the external installation is about 4mm, the size is variable. Aluminum-plastic plate standard specifications :1220*2440*4mm/3mm, the thicker the aluminum skin, the better the relative quality, the more expensive, other sizes can be negotiated with the manufacturer according to requirements.
Aluminum-plastic panel specification measurement
These measuring points should include at least four corners
Thickness: With a thickness measuring instrument with a minimum index value of 0.01mm, measure the thickness at least 20mm from the edge of the plate, and the thickness at many places including the midpoint of the four sides. The limit error between all the measured values and the nominal values is taken as the test result.
Length (width): The length is on both sides of the width of the board, and the width is measured on both sides of the length of the board with a steel tape measure with a minimum division value of 1mm. Full measurement in length (width)
The limit error between the value and the nominal value is taken as the test result.
Diagonal difference: Use a steel tape with a minimum division value of 1mm to measure and calculate the difference between the two diagonal lengths on the same plate, and take the maximum of all the measured differences as the test result.
Edge straightness: Place the board flat on the level platform, use the side of the 1000mm long steel ruler to lean against the edge of the board, and then use the feeler ruler to measure the maximum gap between the edge of the board and the side of the steel ruler. The maximum value of all measured values on each side is taken as the test result.
Warping degree: Place the concave surface of the plate on the horizontal platform, and use a steel ruler with a length of 1000mm to stand on the plate, and then use a ruler with a minimum division value of 0.5mm to measure
Maximum gap height between ruler and board. The maximum value of all the measured values is taken as the test result.
Aluminum thickness: The aluminum removed from the sample is used as the test piece. Measure the thickness of the aluminum with a thickness measuring instrument with a minimum division value of 0.001mm (should not include coating)
Such as the thickness). The measurement should be carried out in enough places, but at least 5 parts of the corners and center should be measured on each specimen. The minimum and arithmetic mean values of all the measured values were taken as the test results.
Coating thickness: Coating thickness refers to the total thickness of the coating, in accordance with the provisions of GBIT4957 on the specimen in sufficient places to test.
