example 1A

[0120] [Example 1A] Preparation of a soil stabilization composition comprising a salt of lysine and citric acid and a thickening agent: the molar ratio of lysine to citric acid is 1.5:1 and the amount of solid content of lysine and citric acid is 50% by weight

[0121] 53.33 grams of distilled water (DIW) were added to 100 grams of a 54% by weight aqueous solution of L-Lysine freeform and then stirred at room temperature (25°C) for 30 minutes while the lysine was diluted . To the diluted lysine was slowly added 47.31 grams of citric acid (CA) and xanthan gum over 1 hour at room temperature (25°C) while stirring. Then, the resultant was stirred at a temperature of 60°C for 1 hour. Subsequently, the reaction was terminated after the reaction mixture reached room temperature (25°C) to obtain 202.62 g of a soil stable composition. Based on 100 parts by weight of the soil stabilization composition, the solid content of lysine and citric acid in the soil stabilization composition...

[0122] [Example 1B] Preparation of soil stabilization composition comprising salts of lysine and citric acid, thickener and stabilizer: the molar ratio of lysine to citric acid is 3:1 and the solid content of lysine and citric acid The amount is 50% by weight

[0123] A soil stabilization composition was prepared in the same manner as used to prepare Example 1A, except that the molar ratio of lysine to citric acid was 3:1.

example 1C

[0124] [Example 1C] Preparation of a soil stabilization composition comprising a salt of lysine and citric acid, a thickener and a stabilizer: the molar ratio of lysine to citric acid is 1:3 and the solid content of lysine and citric acid The amount is 50% by weight

[0125] A soil stabilization composition was prepared in the same manner as used to prepare Example 1A, except that the molar ratio of lysine to citric acid was 1:3.

Abstract

The invention provides: a method for suppressing dust generation, a soil stabilization composition comprising salts of lysine and citric acid and a solvent, and a spraying device comprising the soil stabilization composition. The method for suppressing dust generation includes: preparing a soil stabilizing composition, the soil stabilizing composition comprising salts of lysine and citric acid and a solvent; and spraying the soil stabilizing composition on the soil.

Description

technical field [0001] The present application relates to a method of inhibiting dust generation, a soil stabilizing composition, and a spray device comprising the same. Background technique [0002] Soil stabilizers usually contain inorganic salts as a main component to suppress dust generation in the soil, or water-soluble polymers as a main component to improve the water absorption properties of the soil. Inorganic salts are easily removed from the surface horizon by rain or the like. Inorganic salt soil stabilizers such as magnesium chloride (MgCl 2 )) requires a constant supply of water to maintain dust suppression activity. When the surface of the soil is dehydrated, the inorganic soil stabilizers are deposited on the surface of the soil in the form of crystalline salts. In this case, the inorganic soil stabilizer itself is a source of dust. Inorganic salt soil stabilizers are dissolved by rainwater, and are easily removed from the superficial layer and flow into r...
