Embodiment 1
[0030] 1. Wash the abalone shell with water to remove impurities such as silt, drain and dry in a constant temperature blast drying oven at 90°C for 30 minutes;
[0031] 2. Put the dried abalone shell into the muffle furnace for calcination, the calcination temperature is 800°C, and the calcination time is 100min to obtain the abalone shell ash;
[0032] 3. Put the calcined abalone shell ash into the crushing equipment for coarse crushing to obtain abalone shell ash powder with a particle size of 30 mesh;
[0033] 4. Mix abalone shell ash powder with water to make milk of lime, and the mass ratio of the abalone shell ash powder to water is 1:14;
[0034] 5. Add abalone shell lime milk to the ultrasonic equipment, slowly add lactic acid solution with a mass percentage concentration of 50% according to the mass ratio of lactic acid solution and lime milk at a mass ratio of 8:15, ultrasonic treatment accelerates the reaction, ultrasonic power is 200W, ultrasonic The frequency is...
