Embodiment 1
[0025] In the present embodiment, the method for surface modification of negative ion dry powder, its specific steps are as follows:
[0026] a. Add 5g of surfactant to 100g of water, stir under electric power, the stirring speed is 800 rpm, heat to reaction temperature 75°C, then add 15g of 1000 mesh negative ion powder to obtain a mixed solution;
[0027] b. The mixed solution is subjected to constant temperature ultrasonic treatment for 15 minutes in an ultrasonic cleaning machine, and the frequency used by the ultrasonic cleaning machine is 25KHz;
[0028] c. Continue the constant temperature electric stirring reaction for 0.5h, and the stirring speed is 1000 rpm;
[0029] d. After the reaction is completed, the mixed solution is filtered, and the solid is taken, dried at 100° C. to constant weight, pulverized, and passed through a 200-mesh sieve.
