TABLE 1
From the experimental conclusion in table 1, if too much potassium humate is added, the viscosity of the soil surface is smaller and the hardness is higher after the environment-friendly dust suppressant is used, so that the soil is hardened, if no potassium humate is added, the hardness and the crust thickness of the soil surface are both increased after the environment-friendly dust suppressant is used, so that the soil is hardened, and therefore, the addition amount of the potassium humate needs to be controlled between 0.4 and 1 part; if the vegetable gum is removed, the environment-friendly dust suppressant has the advantages of smaller viscosity, smaller hardness and thicker crust thickness on the soil surface, and the soil is hardened after the vegetable gum is removed; if cold water soluble starch (modified starch) is replaced by cationic starch, flocculation occurs in the solution, and after the environment-friendly dust suppressant is used, the viscosity of the soil surface is smaller, the hardness is smaller, so that the ideal dust suppression effect cannot be achieved.
Table 2 is an environmental protection dust suppressant: the water is prepared according to the concentration ratio of 1:150 and the experimental data table, and the specific results are as follows:
TABLE 2
From the experimental conclusion in table 2, if too much potassium fulvate is added, the viscosity of the soil surface is smaller and the hardness is improved after the environment-friendly dust suppressant is used, so that the soil is hardened, if the potassium fulvate is not added, the influence on the soil is small after the diluted environment-friendly dust suppressant solution is used, and the addition amount of the potassium fulvate needs to be controlled between 0.4 and 1 part by combining the results in table 1; if the vegetable gum is removed, the environment-friendly dust suppressant has the advantages of smaller viscosity, smaller hardness and slightly increased crust thickness on the soil surface, and the soil is hardened after the vegetable gum is removed; if cold water soluble starch (modified starch) is replaced by cationic starch, flocculation occurs in the solution, and after the environment-friendly dust suppressant is used, the viscosity of the soil surface is smaller, the hardness is smaller, so that the ideal dust suppression effect cannot be achieved.
The data from the above experiments were averaged over three experiments.
From the appearance color, the added potassium fulvate solution shows black, the color is related to the added potassium fulvate, the more the added potassium fulvate is, the darker the color is, and the viscosity is not greatly influenced by the small amount of the added potassium fulvate.
