EPS is widely used in machinery and equipment which caused great pollution

EPS expanded polystyrene is widely used in machinery and equipment, instrumentation, household appliances, handicrafts and other shockproof packaging materials that can damage valuable products. Has the relative density of small (1.05g / cm3), low thermal conductivity, water absorption, shock-resistant, heat insulation, noise, moisture, vibration absorption, excellent dielectric properties and so on. EPS expanded polystyrene has become an important packaging material, EPS expanded polystyrene production with the advantages of EPS expanded polystyrene continues to increase, over time caused a huge problem of how to proceed EPS Recycling?

EPS Styrofoam Recycling 1. Recycling granulation: the use of heat, cold crushing or cold compression process to reduce the volume of EPS waste through EPS densifier, and then re-granulation. The EPS particles can then be directly used to make plastic products, such as hangers, flowerpots, video tapes, furniture, building materials, insulation materials, etc., by mixing the EPS particles with other polymer raw materials (such as linear SBS) into a plastic alloy.

EPS Styrofoam Recycling Method 2. The EPS waste is crushed and mixed directly with other materials (such as concrete, gypsum or natural fiber) as low density additives to make light new materials: (1) lightweight roofing insulation material; (2) concrete foam insulation board; (3) fiber reinforced insulation board; (4) plant fiber reinforced insulation materials;

EPS Styrofoam Recycling 3. The chemical method of polymer cracking monomer recovery or the formation of mineral spirits. Waste polystyrene pyrolysis and catalytic cracking of styrene and aromatic oil Waste polystyrene foam at 360 ℃, 150min after pyrolysis fractionated boiling range 144 ~ 146 ℃ fraction of styrene, the yield was 70% , Such as waste polystyrene foam in the amount of catalyst was 1/20 of waste polystyrene and 260 ℃ pyrolysis reaction 60min, styrene yield of 83%, a colorless oily liquid. The other fractions were benzene, toluene, alpha-methyl styrene, cumene, propyl benzene, polystyrene and di-and trimer.
