Examples
Embodiment 1
[0023] Weigh 1.1g CaCl 2 , add distilled water to dissolve, and set the volume to 100ml to obtain CaCl 2 aqueous solution. Take another 5g of decoquinate and 1g of sodium alginate, mix, add 194ml of distilled water, stir, make it fully mixed, drop in (dropping speed is 100 drops / min) the above CaCl 2 In the aqueous solution, stirred and reacted for 10 minutes, the formed gel microspheres were taken out, rinsed with distilled water, and dried to obtain decoquinate gel microspheres with a particle size of 3.4 mm.
Embodiment 2
[0025] Weigh 8.3g CaCl 2 , add distilled water to dissolve, and set the volume to 500ml to obtain CaCl 2 aqueous solution. Take another 1g of decoquinate and 5g of sodium alginate, mix, add 494ml of distilled water, stir, make it fully mixed, drop (dropping speed is 60 drops / min) the above CaCl 2 In the aqueous solution, stirred, and reacted for 24 hours, the formed gel microspheres were taken out, rinsed with distilled water, and dried to obtain decoquinate gel microspheres with a particle size of 3.6 mm.
Embodiment 3
[0027] Weigh 4.4g CaCl 2 , add distilled water to dissolve, and set the volume to 200ml to obtain CaCl 2 aqueous solution. Take another 3g of sodium alginate and add 200ml of distilled water to obtain a 1.5% sodium alginate solution, weigh 6g of decoquinate and add it to the above-mentioned sodium alginate solution, stir, and make it fully mixed; Add CaCl at a rate of 10 drops / min 2 In the aqueous solution, after reacting for 72 hours, the formed gel microspheres were taken out, rinsed with distilled water, and dried to obtain decoquinate gel microspheres with a particle size of 4.1 mm.
