Quantitative study on erosion degree of bone china glaze by common acid reagent at different temperature

In this experiment, we selected "Tangshan bone china" 10.5-inch white porcelain flat plate produced by five different enterprises as experimental samples to study the erosion of bone porcelain enamel by different kinds of acidic reagents at different temperatures. The specific experimental process was as follows: at different temperatures, 20% hydrochloric acid, 30% sulfuric acid, 100 g/L citric acid and 10% acetic acid were used to continuously erode the sample glaze for 10h, and the whiteness and 45 degrees mirror direction gloss were measured every 2h. The results show that different acidic reagents at different temperatures have significant differences in the erosion characteristics and strength of bone porcelain glaze, and the corrosion resistance of products from different enterprises also have significant differences.
