Acid in rust contamination aging process, we will continue to bring oil or other impurities, which suspended impurities can be removed by scraping fishing methods; aluminum four-way when the soluble iron content exceeds a certain bath rust the effect will not only greatly reduced, and an excess of iron mixed with the residue of the workpiece surface groove aluminum phosphide Stone Which is good, accelerated aging phosphate bath pollution, seriously affecting the quality of the workpiece phosphate, general acid solution iron content should be controlled at no more than 6% to 10% is appropriate. Bath must be replaced when more than control targets.
