How to distinguish the quality of extruded sheet

Today, the quality of a extrusion board is how to see out, let dongguan extrusion board, dongguan XPS extrusion board and dongguan heat insulation board manufacturers tell you. Generally speaking, it can be seen from the raw materials, generally speaking, the quality of the extrusion sheet quality of the degree from the high can be divided into, the white crystal extrusion board is greater than the blue extrusion board, blue extrusion board is greater than the black extrusion board. As for the red and yellow extruded panels, the quality is about the same as the blue extruded panels.

Generally speaking, see the quality of the extruded board

The first is to see the micro structure of the extruded plate, which is determined by the role of the extruded plate, because one of the functions of the extruded plate is that it can be used as a heat preservation plate, so the micro structure of the extruded plate must be continuous and uniform closed-cell honeycomb structure, holes are generally distributed very evenly.

The second is to use finger pressure to confirm that the white crystal plate will not appear after pressure pressure, blue extrusion plate will have shallow traces, black extrusion plate will be seriously deformed.
