EPS foam recycling technology recycling is the most important measures of environmental harm, recycling is also known as re-resource technology. At present, many scientific research units at home and abroad on the EPS recycling research, and some have reached the level of practical, large transport machine 02826240333 has reached the practical degree of several EPS recovery technology methods were described. First, the mechanical recycling This method can be divided into simple regeneration and composite regeneration of two, EPS foam mechanical simple regeneration is mainly used for the production of corners of the waste, but also easy to clean the recycling of disposable waste, its composition comparison Simple, clean, renewable materials can be used alone or in a certain proportion of the use of new materials can also be used in existing technology and equipment, is the main and effective use of the current method. 1. Recovery of production XPS EPS waste by pulverizing the material, the preparation of PS, and then heated by adding foaming agent, flame retardants, nucleating agents and other additives, processed by the system obtained XPS, widely used in building materials. At present, the recycling technology in the country has been a large area of promotion, and become one of the main ways EPS recycling (data query: Dachuan machine). 2. Recycling foam manufacturers can be scrap and unqualified products broken by crusher into a certain size of the particles, mixed with fresh pre-beads in the sheet metal forming machine or packaging machine in the molding, made of a variety of specifications and shape Of EPS products. After the production practice proved that the product performance to meet the national standard GBl0801-2002 under the premise of broken particles can be between 10% to 25%, that is, you can save raw materials 10% to 25%. 3. Hot melt regeneration, the use of foam pellet machine hot melt regeneration points the following process. One process is to waste EPS foam at 140 ℃ ~ 190 ℃ under constant temperature baking, so that shrinkage defoaming, foam plastic plant after cooling to crush. Baking will produce flammable gases, need to take effective measures to pay attention to production safety. Another process is to first break the scrap, and then the use of a screw propeller foam particles forced into the extruder barrel by heating and melting extrusion, pull, cooling, pelletizing into renewable particles, EPS foam plastic machinery Is the most practical.
