Rubber mixing Mooney viscosity on-line soft-measuring method

Abstract

The invention relates to a rubber mixing Mooney viscosity on-line soft-measuring method, which uses first sample sampling to replace conventional air-cooled placing sampling, builds a Mooney viscosity predicting model by utilizing algorithm of a support vector machine function, and accordingly uses detection data of a first sample to predict the Mooney viscosity value detected by a conventional air-cooled placing process. The on-line soft-measuring method including: adopting a Mooney detection device to measure the Mooney viscosity value and recording the value as xi after the first sample of mixing sizing materials of an ith vehicle is sampled; introducing the support vector machine function K (xi, xj) = (phi (xi), phi (xj)) to build a Mooney viscosity predicting model; introducing xi into the Mooney viscosity predicting model to predict Mooney viscosity value yi of sizing materials of the ith vehicle through a mapping relationship f: x-y, wherein the yi is detected according to the conventional air-cooled placing process; and building a Mooney viscosity on-line soft measuring data base.
