How to retain the fire retardant during XPS recycling-A breakthrough recycling way
The other day we launched a new XPS chips and flakes recycle machine successfully at customer’s site in Beijing. This is a complete new recycle concept for the margins from the XPS production range.
Due to the pressure from conservation, CO2 foam XPS production line is gaining floor. Nevertheless CO2 plastic pellet extruder foam needs co-blowing agent such as for example ethanol or DME etc. that are flammable. How to recycle the XPS margins without loss of fire retardant is really a big challenge besetting every XPS table manufacturers.
Our initiative solves this issue intelligently. The chips and flakes from the margin of the XPS production line or in the unqualified XPS planks will be conveyed to a nourishing silo by surroundings.
These chips and flakes is going to be pushed into kneading extrusion system which will crush and compact it into semi-molten condition. Then the semi-molten lumps is going to be extruded right into a heavy sheet which will come into a pelletizer to create it into little granules as with the picture.
