AI Technical Summary

Technical Problem

In the existing magnetic adhesive preparation process, differences in particle size distribution, crystal phase ratio, and surface oxidation degree between batches of magnetic particle raw materials cause deviations in magnetic property parameters. It is impossible to adjust the ratio in real time during the preparation process, resulting in unqualified finished products and material waste.

Method used

Hysteresis loop data is acquired by an online magnetic measurement device, multidimensional magnetic property feature vectors are extracted, the ratio of magnetic particles and dispersant is adaptively adjusted using a ratio prediction model, and the magnetic properties of the uncured slurry are retested after mixing. Real-time compensation is performed using a compensation regression model to form a closed-loop correction process.

Benefits of technology

This technology enables real-time adjustment of the magnetic adhesive ratio during the preparation process, reducing the deviation in magnetic properties under different batches of raw materials, avoiding the generation of substandard products and raw material losses, and improving the stability and efficiency of production.

Abstract

The application relates to the technical field of magnetic functional material preparation, and discloses a high-precision magnetic glue preparation method, wherein the method comprises the following steps: obtaining hysteresis loop measurement data of current batch of magnetic particles, and extracting a magnetic performance characteristic vector; inputting the magnetic performance characteristic vector and a target magnetic performance index vector into a proportioning prediction model after splicing, and outputting a recommended magnetic particle mass fraction and a dispersing agent adding proportion; calculating accurate mass feeding values of each component and generating a feeding control instruction; performing magnetic performance re-inspection on un-solidified slurry and calculating a deviation vector; performing qualified judgment based on the deviation vector or generating a supplementary feeding instruction through a compensation amount regression model until the deviation converges to a permissible range and then starting solidification.
