[0022]First, take 250g of discarded fluorogypsum from the storage yard, put it into a jet mill for crushing, and after crushing for 10 minutes, pass through a 130-mesh steel sieve to obtain fluorogypsum powder for later use; then take 150g of fresh spinach, and manually select to remove rotten leaves, Put the weeds in deionized water, wash once to remove the residual dirt on the surface, then evenly spread the washed spinach in the pineapple sieve, and put it in the sun to turn it in the sun, and turn it every 2 hours until the spinach is in the sun. When the water content is 2%, stop tumbling, move it to a pulverizer, pulverize for 5 minutes, and pass through a 120 mesh sieve to obtain spinach powder, which is placed in a 2L beaker; then add 1000mL mass concentration It is a 78% ethanol solution, mixed well, placed in an ultrasonic oscillator, set the ultrasonic frequency to 22KHz, and the ultrasonic power to 100W. After ultrasonic oscillation for 1 hour, filter to remove the ...

[0025] Firstly, take 300g of discarded fluorine gypsum from the storage yard, put it into a jet mill for crushing, and pass through a 140-mesh steel sieve after crushing for 13 minutes to obtain fluorine gypsum powder for later use; then take 200g of fresh spinach, and manually select to remove rotten leaves, After weeds, put them in deionized water, wash them twice, remove the residual dirt on the surface, then spread the washed spinach evenly in the pineapple sieve, put them in the sun and turn them in the sun, and turn them every 2 hours until the spinach is in the sun. When the water content is 3%, stop tumbling, move it to a pulverizer, pulverize for 7 minutes, and pass through a 125 mesh sieve to obtain spinach powder, which is placed in a 2L beaker; then add 1050mL mass concentration It is a 78% ethanol solution, mixed well, placed in an ultrasonic oscillator, set the ultrasonic frequency to 28KHz, and the ultrasonic power to 110W, and after ultrasonic oscillation for 1....

[0028] First, take 350g of discarded fluorogypsum from the storage yard, put it into a jet mill for crushing, and after crushing for 15 minutes, pass through a 150-mesh steel sieve to obtain fluorogypsum powder for future use; then take 220g of fresh spinach, and manually select to remove rotten leaves, Put the weeds in deionized water, wash 3 times, remove the residual dirt on the surface, then spread the washed spinach evenly in the pineapple sieve, put it in the sun and turn it in the sun, and turn it every 2 hours until the spinach is in the sun. When the water content is 4%, stop tumbling, move it to a pulverizer, pulverize it for 8 minutes, and pass through a 130 mesh sieve to get spinach powder, which is placed in a 2L beaker; then add 1100mL mass concentration to the above beaker containing spinach powder It is a 78% ethanol solution, fully mixed, placed in an ultrasonic oscillator, set the ultrasonic frequency to 30KHz, and the ultrasonic power to 120W. After ultrasoni...
