Examples
Embodiment 1
[0022] Mix quicklime and hydrochloric acid at a molar ratio of 2:1, and stir evenly. After the reaction is complete, mix with crushed and sieved potassium feldspar and activated carbon at a mass ratio of 0.8:1:0.2 to obtain a mixed material, add water to mix, and stir evenly , and then put the mixed material into the wheel kiln, calcined at 900 ° C for 30 minutes, let in air to cool to room temperature, cool, take out, crush, and pass through 80 mesh sieve to obtain the activated product of potassium feldspar.
[0023] The potassium feldspar activation product obtained in this example is tested according to the agricultural testing standards NY / T2272-2012, NY / T1973-2010 and NY / T2540-2014, and the results are as follows:
[0024] name
Embodiment 2
[0026] Mix slaked lime and hydrochloric acid at a molar ratio of 2:1, stir evenly, and mix with crushed and sieved potassium feldspar, gypsum powder, and activated carbon at a mass ratio of 0.9:1:0.15:0.1 to obtain the mixed material , add water to mix, stir evenly, and then put the mixed material into the vertical kiln, calcinate at 950 ℃ for 40 min, cool, take out, crush, and pass through a 100-mesh sieve to obtain the activated product of potassium feldspar.
[0027] The potassium feldspar activation product obtained in this example is tested according to the agricultural testing standards NY / T2272-2012, NY / T1973-2010 and NY / T2540-2014, and the results are as follows:
[0028] name
Embodiment 3
[0030] Mix limestone and hydrochloric acid at a molar ratio of 2:1, stir evenly, and mix with crushed and sieved potassium feldspar and calcium sulfate at a mass ratio of 1:1:0.2 after the reaction is sufficient to obtain a mixed material, add water and mix, Stir evenly, then put the mixed material into the rotary kiln, calcinate at 950°C for 30 minutes, cool, take out, crush, and pass through an 80-mesh sieve to obtain the activated product of potassium feldspar.
[0031] The potassium feldspar activation product obtained in this example is tested according to the agricultural testing standards NY / T2272-2012, NY / T1973-2010 and NY / T2540-2014, and the results are as follows:
