After the waste foamed plastic is crushed, it is heated by infrared radiation, and its volume is reduced to less than 1/20; then it is mixed with special cement to make a popcorn-like building material, which is recognized as a non-combustible building material. PS wood substitute Recycled PS can be used as a wood substitute, as a substitute material for house construction and furniture production. One of the reasons this material is attractive is that it has the same properties as wood in terms of appearance, feel, density and structural properties. Dissolve EPS waste in a solvent and directly use it as a paint, adhesive or caulk .

The waste polystyrene foam is specially treated to produce a new type of water-based emulsion paint with water as the medium, which is an ideal moisture-proof coating agent for corrugated boxes. Products. The processes with industrialization potential in current chemical recovery are cracking, vaporization, hydrogenation, and pyrolysis. This material has now been used for the oem Parallel Twin Screw Barrel for Plastic Extruder Machine Manufacturers walls and ceilings of various soundproofing facilities. The method is to decompose waste EPS into reusable components such as monomers, compounds, and fuels, making EPS recycling a truly closed-loop process.

This brick has high strength and excellent thermal insulation performance. Or it can be used by mixing new materials in a certain proportion, or it can use existing technology and equipment, which is currently the main adopted and proven method. Dissolve to make paint, etc. Compared with mechanical recycling, this method has the following advantages: the quality of the chemical raw materials generated by decomposition can be comparable to that of new materials; in addition, it has the potential to treat a large amount of waste, which can realize re-resources and achieve the real pollution of EPS to the environment. Hot melt regeneration, using foam plastic pellet machine Hot melt regeneration is divided into the following processes. Pyrolysis and catalytic cracking of waste polystyrene to prodauce styrene and aromatic hydrocarbon oil. The composition is relatively simple and clean, and the recycled materials can be separated. The granular material made by gelation method can also be reused to make polystyrene foamed plastic products after air-drying to a solvent content of 6%-10%. Loose filler The loose packing can be made of 100% PS and used as packing packing around the consigned objects in the box to prevent the objects from being damaged. 1. At present, this recycling technology has become one of the main ways in China. The excellent shock absorption performance and low غير مجاز مي باشدt of EPS foam make it an ideal packaging material.. It is also possible to mix colloidal clay and EPS crushing material according to a certain ratio, and roasting at high temperature.

Recycling Foam manufacturers can crush leftovers and unqualified products into particles of a certain size by a crusher, mix them with fresh pre-expanded beads, and reshape them in a sheet forming machine or a packaging forming machine to produce EPS of various specifications and shapes. As a feasible method of reconciling EPS and the environment, chemical recycling has attracted the attention of various countries. The production practice has proved that under the premise that the product performance meets the national standard GB10801-2002, the mixing amount of the broken particles can be between 10% and 25%, that is to say, 10% to 25% of raw materials can be saved. Application of Recycling Styrofoam Packaging foam Recycled EPS is widely used to protect packaging foam inside. Chemical cracking Use chemical methods to crack the polymer to recover monomers or generate mineral spirits. Lightweight new material made by blending The EPS waste is crushed directly as a low-density additive and mixed with other materials (such as concrete, gypsum or natural fiber) to produce lightweight new materials: lightweight roof insulation materials, concrete foam insulation boards, fiber-reinforced sound insulation insulation boards, and plant fibers Enhanced insulation materials and sound insulation bricks. In addition, EPS crushed materials can also be made into lightweight blocks, thermal insulation mortar and lightweight mortar for internal and external walls. Dissolve styrene foam in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones or coolers, add additives after reaching a certain concentration, and stir evenly to produce waterproof coatings, and then add different pigments to become colorful The coating can be sprayed on the exterior wall or cement floor of the building, the outer layer of the packing box or packing box, to play a waterproof role. Although chemical recovery is not new in terms of reaction mechanism, there are still many engineering problems that need to be solved if it is to be put into practical use. Then use the prepared EPS particles directly or mix the EPS particles with other high polymer materials  into plastic alloys to make plastic products, such as hangers, flower pots, video tapes, furniture, building materials or insulation materials.The recovery rate is 70% . 3. Another process is to crush the scraps first, and then use a screw propeller to forcefully add the foam fragments to the extruder barrel, heat, melt, extrude, stretch, cool, and cut into recycled pellets. Materials, housing construction and other fields have been widely used. Recycling production XPS After EPS waste is pulverized and made into materials, PS is prepared, and then it is heated and melted to add foaming agent, flame retardant, nucleating agent and other additives, and processed to obtain XPS, which is widely used in building materials.
