Examples
Embodiment 1
[0047] The shells of the mussels were soaked in an aqueous NaOH solution with a concentration of 1% by mass for 0.5 hours, and then soaked in an aqueous solution of HCl with a concentration of 5% by mass for 0.5 hours. After soaking, rinse with distilled water, dry, and then grind to a particle size of 150 μm with a roller mill.
[0048] Calcining and activating the shell powder obtained above at 800°C for 1 hour, adding 0.5% by mass of sodium stearate and mixing, stirring evenly, drying, and then sieving to obtain an active shell skeleton material with a particle size of 150 μm.
[0049] The active shell skeleton material and dodecyl dimethyl benzyl ammonium chloride are fully and uniformly mixed in a mass ratio of 7:2 to obtain the powdered ballast water fungicide of the present invention.
Embodiment 2
[0051] Soak the shells of pearl oyster and meretrix meretrix with a mass percentage concentration of 2% for 1 hour with a mass ratio of 1:1, and then use a mass percentage concentration of 5% H 2 SO 4 Soak in water solution for 1 hour. After soaking, rinse with distilled water, dry, and then grind to a particle size of 160 μm with a roller mill.
[0052] Calcinate and activate the shell powder obtained above at 900°C for 1.5 hours, add 1% of its mass of sodium dodecylbenzenesulfonate and mix, stir evenly, dry, and then sieve to obtain active shells with a particle size of 160 μm Skeleton material.
[0053] The active shell skeleton material and octyldiethylbenzylammonium sulfite are fully and uniformly mixed in a mass ratio of 8:2 to obtain the powdered ballast water fungicide of the present invention.
Embodiment 3
[0055] The shells of the clams were soaked in 2% NaOH aqueous solution for 0.7 hours, and then soaked in 5% HCl aqueous solution for 0.8 hours. After soaking, rinse with distilled water, dry, and then grind to a particle size of 170 μm with a roller mill.
[0056] Calcinate and activate the above-mentioned shell powder at 1000°C for 2 hours, add 2.5% of its mass of sodium lauryl alcohol ether sulfate and mix, stir evenly, dry, and then sieve to obtain active shells with a particle size of 170 μm Skeleton material.
[0057] The active shell skeleton material and pentadecyldipropylphenylpropylammonium bromide are fully and uniformly mixed in a mass ratio of 7:3 to obtain the powdered ballast water fungicide of the present invention.
