AI Technical Summary

Technical Problem

The existing phosphor bronze oxidation process has problems of uneven oxidation and blackening layer loss, resulting in poor oxidation effect.

Method used

The ultrasonic heating cell is used to perform the oxidation process of phosphor bronze filler. By heating and vibrating the reaction liquid in the ultrasonic heating cell, combining sodium chlorite and sodium hydroxide as chemical reagents, the filler is oxidized, and the filler is moved up and down through driving to ensure uniform reaction.

Benefits of technology

The uniformity and thoroughness of the oxidation and blackening of the phosphor bronze surface is achieved, which significantly improves the firmness of the blackening layer, avoids gray drop, and improves the wear resistance and corrosion resistance of the filler.

Abstract

The invention discloses a phosphor bronze filler oxidation process. The process comprises the following steps: S1, feeding materials into an ultrasonic heating tank; s2, operating the ultrasonic heating tank, and heating the ultrasonic heating tank to a specified temperature; s3, after the surface of the filler is cleaned, the filler is loaded into an ultrasonic heating pool to be oxidized; s4, in the oxidation process, observing the color purity of the oxidized filler; s5, after oxidation work is completed, the filler is lifted up; s6, the filler is rinsed; and S7, airing the filler. The filler is subjected to oxidation treatment, so that the wear resistance and corrosion resistance of the filler are improved; the filler is oxidized through sodium chlorite and sodium hydroxide, in the reaction process, the filler is moved up and down through the travelling crane, reaction liquid in the heating tank circularly moves through the ultrasonic unit and the circulating unit, the concentration distribution is uniform, the oxidation blackening effect of the surface of phosphor bronze is good, oxidation is more uniform and thorough, and the production efficiency is improved. And the ash falling phenomenon of the blackening layer is obviously improved.
