Identify The Old Material Of The Hollow Sheet

- Aug 18, 2018-

Hollow sheets are widely used in various industries. Due to the high demand of hollow plates, many hollow plates manufacturers produce with used materials during the production process. The quality of such hollow plates is seriously affected.


(1) the thick and straight vertical vertical bar is a good quality hollow plate product, and the thin vertical bar and the bending of the pressure will indicate the poor quality of the plate.


(2) black spots appear on the hollow plastic plate, and the crystal points are marked as containing impurities. The more impurity content, the more old material content. Good plastic hollow plate must be clean, transparent.


(3) it can also judge the quality of materials used by observing the fluidity of molten liquid of hollow plate. Due to the long molecular chain of carbonate resin, repeated high temperature melting will destroy its molecular structure, from large molecules into small molecules. When the old material is melted again at high temperatures, the chains of its molecules break off, increasing its mobility. Therefore, in theory, the better the data flow in the molten state, the worse the quality.
