It is understood that most of the polystyrene plastic particles are used at one time. After millions of tons of white garbage are discarded, they are placed in the natural world. They can neither be rotted and transformed, nor can they be explained by themselves, thus forming a serious environmental pollution on the one hand. On the other hand, it is also a waste of valuable non-renewable resources. How to effectively recycle used polystyrene foam has attracted the attention of researchers in various countries.
At present, the recycling and recycling of waste polystyrene foam is carried out by crushing, melting and re-granulating into another material particle, and then adding a corresponding non-adjuvant to be processed into another material. For the above-mentioned recycling and recycling method, the common practice is to crush, melt, pull, cut, etc. the plastic foam through the crusher, but in the method of producing the plastic pellet, there is an incomplete pulverization of the raw material, and the temperature control of the melting It is uneven, and impurities that are mixed in the raw materials cannot be avoided, which results in extremely low production efficiency and damage to the equipment due to the presence of impurities. The production method of polystyrene foam regeneration resource relates to the field of processing and preparation of recycled granules, by selecting raw materials, air drying, pulverizing, primary impurity removal, melting, extrusion molding, secondary impurity removal, cooling, cutting, quality inspection, packaging Library.
Polystyrene plastic particles are one of the most widely used plastics in the world. Due to their good water resistance, thermal insulation, insulation, low moisture absorption and strong seismic strength, they are light, strong and easy to form. Low price and other characteristics, widely used in packaging, moisturizing, waterproof, heat insulation, shock absorption, decoration, catering and other fields, into the various sectors of the national economy.
