| titleOfInvention | Treatment method for smooth surface of oyster shell |
| abstract | The present invention relates to a processing method for smoothing the surface of oyster shells, including the following steps: A. Wash the oyster shells with clean water; B. Configure an organic acid solution with a concentration of 7.5% to 17.5%; C. Heat the organic acid solution To 55℃~85℃; D. Immerse the oyster shell in the organic acid solution and soak for 3~5 minutes to dissolve the surface of the oyster shell and make it smooth; E. Take out the oyster shell and Clean water to wash away the residual acid on the surface of the oyster shell. In this way, the surface of the oyster shell is smoothed, and the waste organic acid solution after treatment will not have the disadvantage of polluting the ecological environment. |
