EPS Foam Recycling Technology Method 2

Another process is to first break the scrap, and then use the auger to the foam pellet forced into the extruder barrel by heating and melting extrusion, pull, cooling, pelletizing into renewable particles, EPS foam plastic machinery Is the most practical.
There is also a process is to first waste EPS foam immersed in a high boiling point mixed solvent to defoamate and become a gel material, and then with the modified resin, additives, multi-stage exhaust extrusion granulation, while condensation Recovery solvent. Granulation of the product is reinforced polystyrene, can produce stationery, toys and a variety of daily necessities and electrical and electronic components. Gels made by the method of gelling, air-dried to the solvent content of 6% ~ l0%, can also be re-used in the manufacture of polystyrene foam plastic products.
Second, the production of lightweight insulation materials Waste foam was crushed, after infrared radiation heating, the volume reduced to 1/20 below; and then mixed with special cement, made of rice candy-like building materials, was identified as non-flammable Building materials. The silhouette of this building material is an average of 60%, for some frequencies of noise suppression can reach more than 90%. This material has now been used as a wall and ceiling for various soundproofing facilities. In addition, EPS broken material can also be made of lightweight blocks, inside and outside the wall of the insulation mortar and light mortar. It is also possible to mix the clay and the EPS crushed material by a certain ratio, the foaming machine is burnt at high temperature, the EPS crushed material is burnt to produce a clay brick with a hollow structure, which has a high strength and excellent Adiabatic performance.
Third, chemical recycling Chemical recycling as a way to reconcile the feasibility of EPS and the environment by the attention of countries, the method is the decomposition of EPS into monomer, compounds, fuels and other reusable ingredients, EPS recovery truly closed-loop process. This method has the following advantages over mechanical recovery: the quality of the chemical raw material produced by the decomposition can be comparable to that of the new material. In addition, it has the potential to deal with the waste, that is, the resource can be realized and the real pollution of the EPS The Consulting 02826240222 Current chemical recovery in the industrial potential of the process is cracking, vaporization, hydrogenation, pyrolysis. Although the chemical recovery from the reaction mechanism is not new, but all into the practical, there are many engineering problems need to be resolved.
Fourth, other recycling technology 1. Manufacture of rust-proof anti-rust paint; 2. Manufacture of multi-functional resin; 3. Manufacture of anti-seepage and leakage agent; 4. Asphalt enhancer.
