Teach you to identify the quality of hollow board products

The market a lot of the same type of hollow plate manufacturers; in the hollow board raw materials by adding a non-plastic filler (calcium carbonate powder), greatly reduce the cost of production to win the price, some companies can reach 50% of the filler, filling 20 % Of the following is difficult to distinguish with the sensory, but significantly reduced the life of the hollow plate of the five physical and mechanical properties are seriously affected, so the quality of hollow plate material to identify a test when the standard: pull force N, tear N, elongation at break%, vertical compressive force N, plane compressive force N, melt flow index of incoming material detection. In addition, anti-static hollow board, conductive hollow board also has a variety of processing methods, quality and production cost gap is also quite large, it is difficult to distinguish the authenticity. When the hollow board did not meet the above testing standards, the use of this product is easy to break in the circulation process, resulting in users suffered huge losses.
At present, the domestic hollow board market is highly competitive, whether the hollow board products have a direct production base, whether the production of hollow plate materials, equipment and R & D production turnover box products capacity is also worth noting.
