| Abstract: | The influence of bentonite as a suspending agent on the processing and performance of the final enamel product was studied with the aim of prolonging the service life of enamel. The suspension stability of the glaze slurry was also evaluated, and the influence of the layered structure of bentonite on the suspension was explored. In addition, the effect of bentonite on the flexural strength and fracture toughness of enamel coatings on metal substrates was investigated. Finally, acid corrosion resistance experiments were performed to evaluate the effect of bentonite on the corrosion performance of the enamel coating. The results showed that the stability of the glaze slurry and mechanical properties of the enamel products were significantly improved by adding 1 wt% bentonite to the glaze slurry. The addition of 0.5 wt% bentonite was optimal for enhancing the acid corrosion resistance of the enamel. This study provides a useful reference for improving the quality of enamel products and prolonging their service life. |
