Description

Waste foamed plastic recovery process

Technical Field

The invention relates to the technical field of waste recovery, in particular to a waste foamed plastic recovery process.

Background

The foamed plastic is a high polymer material formed by dispersing a large number of gas micropores in solid plastic, has the characteristics of light weight, heat insulation, sound absorption, shock absorption and the like, has dielectric properties superior to matrix resin, and has wide application range. Almost all kinds of plastics can be made into foamed plastics, and foam molding has become an important field in plastic processing. The foam is a polymer material containing a large number of cells and having a plastic as a basic component, and therefore can be said to be a composite plastic having a gas as a filler. Compared with pure plastic, the composite material has many excellent properties, such as light weight, high specific strength, impact load absorption, good heat insulation and sound insulation properties, and the like. Therefore, the method is widely applied to the fields of industry, agriculture, building, transportation and the like.

Waste foamed plastic is because being difficult to natural decomposition, consequently directly can cause white pollution to it, consequently some enterprises can retrieve waste foamed plastic, reuse again after processing, and then reach the purpose of environmental protection, and current recovery operation, generally all need wash operations such as bleaching to the foam, but because the foam only has dirty needs to wash the bleaching in top layer, to some great foams, and then can occupy more space when wasing in batches, not only can reduce abluent efficiency, the great foam of surface area also can influence cleaning performance, consequently to some great foamed plastic, need cut it into the fritter, and the foamed plastic after the cutting, its bright and clean internal surface also can expose and then washed, then water purification and detergent can be wasted this moment, and the cost is improved.
