METHOD AND CONTROLLING SYSTEM FOR CONTROLLING POLYMER VISCOSITY QUALITY

A method for controlling polymer viscosity quality in a compounding process of polymers (110) using at least one extruder (111) is disclosed. The method comprises: a) at least one measurement step (112), wherein at least one influence variable affecting viscosity of the compound is determined by using at least one sensor (114); b) at least one prediction step (116), wherein an expected viscosity (117) of the compound is determined considering the influence variable by using at least one prediction unit (118), wherein the prediction unit (118) comprises at least one analysis tool comprising at least one trained model; c) at least one evaluation step (120), wherein the expected viscosity (117) of the compound is compared to at least one pre-defined and/or pre-determined threshold value, wherein at least one item of output information is generated depending on said comparison; and d) at least one control step (122), wherein the item of output information is displayed using at least one display device (124), wherein the output information comprises at least one handling recommendation (126) for at least one setting of the extruder (111). Further disclosed are a computer program, specifically an application, and a controlling system (138) for controlling polymer viscosity quality in a compounding process of polymers (110).
