Method and system for providing an assembly of an amount of used plastic material and an information carrier carrying quality data of the amount

摘要

Method for providing an assembly of an amount of used plastic material and an information carrier carrying data of at least one quality property of the amount of used plastic material, wherein providing the data of the at least one quality property comprises at least once: providing a predetermined amount of used plastic material; labelling the predetermined amount of used plastic material; and determining at least one quality property of the predetermined amount of used plastic material. A system for providing an assembly of an amount of used plastic material and data of at least one quality property of the amount of used plastic material, wherein the system comprises: a feeder for providing used plastic material; at least one quantity measuring system; a rheology measuring system; and an information carrier.

1. A method for assembling an amount of used plastic material and an information carrier carrying data of at least one quality property of the amount of used plastic material, the method comprising:
providing a predetermined amount of used plastic material from the amount of used plastic material; labelling the predetermined amount of used plastic material; determining at least one quality property of the predetermined amount of used plastic material by at least one of measuring rheology properties of a sample of the predetermined amount of used plastic material to obtain rheology data, and measuring impurity properties of a sample to obtain impurity data; providing the rheology data and/or the impurity data on an information carrier; and labelling the information carrier in a way which corresponds to the labelling of the predetermined amount of used plastic material, wherein measuring rheology properties comprises measuring during extrusion of the sample into an extruded sample at least one of a mass pressure of the sample, a mass temperature of the sample, and at least one of a shear and flow property of the sample.
