With the development of modern industry, with polystyrene foam packaging products more and more, and accordingly this is more and more waste, all over the land, lakes, beaches. The salient features of this type of waste are: in the natural environment, neither rotten nor degrading degradation, as well as bulky, to the recovery of transport caused difficulties.
Styrofoam recycling, with economic and social benefits. Polystyrene foam waste as raw materials, can produce a variety of products. Such as full use, not only will not become public, but a valuable raw material.
Common polystyrene foam waste can be divided into two kinds: one is made after the use of waste products, including waste in the production process of the waste; the other is not made before the finished product has become a material, Ie raw material waste.
Regardless of the kind of waste, in the processing should be pre-treatment, remove the soil, gravel, rubble and weeds and other impurities. Such as the surface of the oil traces also use the alkali to the oil, then washed with water to neutral, since the dry, and then the following processing production.
After pretreatment of large foam foam, no matter what kind of processing, must be crushed into a diameter of about 1 cm small pieces. This waste piece can be used directly for the following production:
Third, the waste rods, cake system of the law
As polystyrene foam waste to diverge, bulky, difficult to transport, can be rough in situ processing, and then transported to the processing plant for production. General use of melting method made of sticks, biscuits, melt volume after melting 7 to 8 times. This solves the problem of long-standing transport of waste in the event of volume. Corresponding to this is a significant savings in transportation costs, reducing production costs.
