Embodiment 1
[0026] Combine 2.25Kg of unactivated powdery weathered coal A and 0.24975Kg of solid activator B, wherein in solid activator B: the mass of sodium oxide and potassium oxide accounts for 70% of the total solid activator B mass ratio, and contains oxidized The mass of basic oxides such as barium and manganese oxide accounts for 30% of the mass ratio of the total solid activator B. Mix A and B thoroughly. Then, add 0.00025Kg synergist C (composed of one or two kinds of nano-copper, nano-iron metal particles) to the mixture of A and B; finally, put the above-mentioned mixture into the ball mill, and adjust the rotating speed of the ball mill to be 80r , the time is 60min to generate activated humic acid. It can be stored for a long time after being bagged, measured, and stored, and the validity period can be 3-5 years. Compared with the traditional liquid activation method, this activation process can be carried out at room temperature, which can save half of the energy (the tem...
Embodiment 2
[0028] With the unactivated powdery weathered coal A of 2.76Kg and the activator B of 0.2391Kg, the sodium oxide and potassium oxide quality that wherein activator B contains account for 75% (mass ratio) of total solid activator B, the barium oxide contained Basic oxides such as manganese oxide and iron oxide account for 25% (mass ratio) of the total solid activator B. Mix A and B thoroughly. Then, add 0.0009Kg synergist (composed of one or two kinds of nano-copper and nano-iron metal particles) to the mixture of A and B. At last, the above-mentioned mixture is put into a ball mill, and the rotating speed of the ball mill is adjusted to be 80r, and the time Activated humic acid can be generated within 60 minutes. It can be stored for a long time after being bagged, measured, and stored, and the validity period can be 3-5 years. Compared with the traditional liquid activation method, this activation process can be carried out at room temperature, which can save half of the en...
Embodiment 3
[0030] With the unactivated powdery weathered coal A of 3.8Kg and the activator B of 0.19992Kg, wherein the sodium oxide and potassium oxide weight that activator B contains account for 80% (mass ratio) of total solid activator B, the barium oxide contained And the quality of basic oxides such as manganese oxide and calcium oxide accounts for 20% (mass ratio) of total solid-state activator B. Mix A and B thoroughly. Then, add 0.0008Kg synergist (composed of one or two kinds of nano-copper and nano-iron metal particles) to the mixture of A and B. At last, the above-mentioned mixture is put into a ball mill, and the rotating speed of the ball mill is adjusted to be 60r, and the time Activated humic acid can be generated within 90 minutes. It can be stored for a long time after being bagged, measured, and stored, and the validity period can be 3-5 years. Compared with the traditional liquid activation method, this activation process can be carried out at room temperature, which...
