[0022]First select 200g of scallop shells, wash them twice with clean water to remove impurities on the surface of the shells, then soak them in hydrochloric acid with a mass fraction of 15%, take them out after soaking for 2 hours, remove the surface organic pollutants, and then put them in Take out after soaking and rinsing twice in ionized water, dry the cleaned shells in a vacuum drying oven at -0.09MPa for 5 hours, put the dried shells into a pulverizer, and sieve to get 120-mesh shell powder; 150g of egg shells, remove the membrane inside the egg shells, soak the egg shells in 1.5L of tap water, add 4g of sodium chloride and 3mL of acetic acid with a mass fraction of 15% to the water, soak for 6h, take out and put in Dry it completely in an oven at 60°C. After drying, put the egg shells into a pulverizer and crush them into 120-mesh powder. Put the powder into a mixing mixer, add the shell powder obtained above, and stir for 40 minutes to make it completely uniform. Mixi...
