AI Technical Summary

Technical Problem

In the existing technology, microcapsules in screw coatings have difficulty in actively responding to mechanical damage and electrochemical corrosion, and their dispersion is unstable in continuous electrophoresis production lines, resulting in uneven coating function and failing to meet the requirements of high-standard mass production.

Method used

The system employs dual-response intelligent microcapsules, combined with a dedicated dispersant and online concentration monitoring, and uses a PLC system to achieve closed-loop control, ensuring that the microcapsules are uniformly suspended in the electrophoresis tank solution and form a self-healing composite coating on the screw surface.

Benefits of technology

It achieves high performance and high reliability self-healing of screw coating, improves protection efficiency and lifespan, and ensures the consistency and reproducibility of coating in large-scale production.

Abstract

The application provides a screw self-repairing electrophoretic coating integrated preparation method, which comprises the following steps: (1) preparation of double-response intelligent microcapsules; (2) surface modification and pre-dispersion of the microcapsules: the surface of the microcapsule powder is modified by using a special dispersant, and then the microcapsule powder is pre-dispersed into a slurry with part of the electrophoretic paint tank liquid; (3) screw pretreatment; (4) intelligent maintenance and co-deposition of the integrated tank liquid: the slurry is injected into the electrophoretic main tank circulating system; the microcapsule concentration is fed back in real time by using an online concentration monitoring device, and the addition rate is dynamically adjusted through a control system; then the screw is subjected to electrophoretic co-deposition; (5) post-treatment: the electrophoretic part is washed with water and then solidified; (6) intelligent monitoring of the whole process. The microcapsules are uniformly and stably suspended in the electrophoretic tank liquid, and the closed-loop precise control of process parameters is realized, so that a high-performance and high-reliability self-repairing composite coating is formed on the surface of the screw.
