Waste polystyrene plastic recycling should be took

Waste polystyrene recycling technology generally hot air heating, friction heat and other methods to melt, reduce the volume, in bulk or granular recovery, can also be recycled EPS particles and new particles mixed with, but in the process of heating shrinkage, due to Oxidation will result in the reduction of plastic properties, coloring, recovery costs and other issues affecting the quality of the newly developed Reno system with natural solvent limonene dissolved in the regeneration treatment equipment to filter, separation of solvents, granulation, made of recycled polystyrene the polystyrene regenerated in this method can be used as a raw material for EPS, in addition to the raw materials for injection molding and extrusion molding.

The use of PS soluble in aromatic hydrocarbons, halogenated hydrocarbons and other organic solvents, the nature of the PS foam can be made of paint or adhesive. Some manufacturers have experimented with PS foam and benzene, kerosene by a certain percentage of mixed and then add the right amount of inorganic filler and inert materials made of modified waterproof material. The use of PS can be dissolved in the nature of asphalt and rosin, with waste PS foam to change the melting point of asphalt, can improve the strength of asphalt and improve the asphalt winter crack summer sticks and overcome the shortcomings of rosin brittle and so on.

Non-solvent heat medium defoaming recovery process of recycle polystyrene is a result of a wide range of comparison and exploration after the current and abroad at home and abroad all the different ideas of thinking another idea, that is, non-solvent heat medium defoaming capacity of the process, discard the discarded polystyrene foam into the defoaming tank while adding a heat medium heated to a temperature to contact the waste foam and fall into the heated tank together with the defoaming material that is defoaming, and then And then defoamed the material and the use of the media separation, can be defoaming recovery material, if the defoamer seal, to achieve pressure operation, the whole process of time for 30-50s.

Due to the absence of reaction and solvation, and the low temperature treatment of defoaming polystyrene foam macromolecular structure and performance is not damaged, the defoaming of the material can be powder into granular, which easy to transport and use.
