PP polypropylene is the main raw material for the production of hollow board production lines, and its finished product is hollow board. After processing, hollow board can be made into turnover boxes, partitions, pads, industrial boards, etc. It involves a wide range of industries, mainly electronics, packaging, machinery, light industry, postal, and so on.
Hollow board is a very popular type of board nowadays, which has high strength, light weight, long service life, and also has good waterproof and anti-static capabilities. Waste hollow boards can also be recycled and reused, which is very helpful for environmental pollution and cost savings. As the raw material for hollow panels, the selection of polypropylene is very important, and the following two points need to be focused on:
1. PP polypropylene has poor moisture absorption, so it generally does not require separate drying treatment. However, if the moisture content in the raw material exceeds 0.1%, it must be dried. The treatment method is simple, and only needs to be dried for 2-3 hours using a hollow board production line in a hot air cycle at 70-80 ℃.
2. The coloring method of PP polypropylene is to use float dyeing or add color masterbatch in proportion to the granular material, mix and stir evenly. If using a plunger type injection machine, to avoid color difference, the evenly mixed color matching material should be extruded and granulated before injection production.
The hollow board production line has been receiving industry attention in recent years. Compared to injection molded products, hollow boards have advantages such as shock resistance and flexible structural design. The application field of hollow boards is constantly expanding, and many industry fields are still under development. It is believed that in the near future, it will receive more applications.
