The common specification of aluminum-plastic composite board is 1.22Mx2.44M, the thickness is 3-5MM, and it can be divided into single-sided and double-sided. According to the thickness of aluminum skin, there are 8 kinds of wires and 30 wires, etc. It can be used in combination with outdoor use, as well as polyester board and carbon board. If it is an outdoor board, it can be customized, and the longest can be 6M long.
Analysis of the purchase points of aluminum-plastic composite panels, the following seven points are worthy of attention:
1. Look - whether the aluminum-plastic panel has a smooth surface, no ripples, bubbling, shelter, and scratches.
2. Measurement - Measure whether the aluminum composite panel meets international requirements, the inner wall panel is 3mm, the outer wall panel is 4mm or more, and the thickness of the aluminum must be 0.5mm.
3, fold - a corner of the aluminum-plastic panel, easy to break is not PE material or doping makes false.
4, burning - aluminum composite board intermediate material, the real PE is completely burned, doping makes the fake after burning there are impurities.
5, planing - when the groove is bent, see if the front is broken.
6, drip - butanone identification of fluorocarbon coating on the outer wall panel, drip xylene to identify the inner wall panel coating, after 5 minutes, wipe off the reagent to see if it is exposed.
7, to - ask the manufacturer quality inspection report, warranty book, ISO-9002 international quality certification, the manufacturers with these are regular manufacturers, can guarantee product quality, the same price than quality, the same quality than the price.
