Measurement system for the determination of mechanical material characteristic values of plastics

摘要

Measurement system for the determination of mechanical material characteristic values of plastics, comprising– a compounding of the device (3; 3c) for generating a plastic - rod (2)– with an outlet element (4), the one for the plastic material - strand (2) forming discharge opening (5) comprises,– the discharge opening (5) is designed in particular in a circular shape,– one of the compounding of the device (3; 3c) in a direction of transport (8) of the plastic - rod (2), which is arranged downstream of the cooling device (9; 9a to 9c) for cooling of the plastic - rod (2),– one of the cooling device (9; 9a to 9c) in the transport direction (8), which is arranged downstream of a delivery device (20, 27) for generating a on the plastic - strand (2) of the force acting in the direction of transport (8),– a measuring device (28), which is designed in such a way that– a mechanical load on the plastic - rod (2) takes place and– at least one of the mechanical loading resulting measurement signal (m) is detectable, and– a control device (7) for determining a mechanical material characteristic value (k) from the at least one measurement signal (m), wherein the cooling effect of the cooling device (9; 9a to 9c) by means of the control device (7) is adjustable.
