It is understood that most of the disposable polystyrene plastic pellets used tens of millions of tons of waste placed in a white trash after nature, neither rot transformation, they can not explain the disappearance of their own, so the one hand, according to a serious environmental pollution on the other hand is also a valuable non-renewable resources, waste, and how people effectively recycling waste polystyrene foam has attracted widespread attention of national research workers. Current methods for waste recycling polystyrene foam is to be broken, melted renewable granulation become another material particles, then add the appropriate without adjuvant, processed into another material. For the recovery of the above-mentioned proposed method of recycling is common practice to pass the foam crusher crushing, melting, brace, cut type, etc., but in the production method for the production of such plastic particles are pulverized starting material was not completely, melt temperature control uneven, but can not avoid some impurities in the raw material mix, this has led to low productivity, and because the presence of impurities can result in equipment damage. The method of making polystyrene foam renewable resources in the areas of processing recycled pellets prepared by selecting raw materials, air-dried, crushed, initial cleaning, melting, extrusion molding, secondary cleaning, cooling, cutting, quality control, packaging into library. Polystyrene particles are the most widely used plastics use in the world today, because of its good water resistance, insulation resistance, insulation resistance, low moisture absorption and strong seismic intensity, and its light weight, rugged, easy to shape low prices, has been widely used in packaging, moisture, water, heat insulation, shock absorption, decorating, catering and other fields penetrate all sectors of the national economy. |
