Nowadays, plastic is a kind of polymer material widely used. It consists of two parts, namely polymer (resin) and additives. There are a wide variety of plastics, and different types have different chemical compositions. The structure is also different, and the plasticity is also different. Therefore, when recycling waste plastics, a plastic granulator should be selected for recycling and granulation. The same plastic has different chemical properties and molecules, so it is more strict and cautious when recycling and granulating. .
Just mentioned that plastics have a wide range of types. In fact, we can divide their unique effects into two types, namely thermoplastics and thermosetting plastics. The first type, within the whole process temperature range of the plastic granulator, can continuously heat, melt and cool the solidified waste plastics; the latter is that most of them cannot be melted after being solidified by heating or other physical and chemical methods . There are many kinds of thermoplastics that are often seen today, such as polyethylene, polyvinyl chloride, polypropylene, polystyrene, etc., and there are many types of thermosetting plastics, such as phenolic plastics, unsaturated polyester plastics, epoxy plastics, etc. . Because thermosetting plastics, etc., cannot be melted or dissolved after being processed by a plastic granulator, we generally go through various processes for waste thermosetting plastics, such as crushing and grinding, but after this treatment, it is only Used as a filler, waste thermoplastic products can be recycled by melting and plasticizing.
