Embodiment 1

[0030] Dissolve polyether L35 in water and prepare solutions with different mass fractions for later use. The method is to prepare 10 parts of polyether L35 solution, 3 parts of anionic polyvinyl acetate copolymer emulsion, After mixing evenly, it is evenly sprayed on the surface of sandy soil with a salt content of 3%, and after the mixture is naturally air-dried, a consolidated layer with good pressure bearing and excellent wind erosion resistance is formed.

[0031] Preparation of sand mold: Dissolve polyether L35 in water to make solutions with mass fractions of 0.5%, 1.0%, 2.0%, 3.0%, and 4.0%, and then use the above polyether L35 solution to anionic polyvinyl acetate copolymer emulsion Diluted to a diluent with a solid content of 3%; take 10g of sand with a salt content of 3% and mix it with 1.0g of the above diluent to prepare a sand mold (2.0cm in diameter and 2.2cm in height), and dry under natural conditions. Get the sand mold.

Embodiment 2

[0038] The alkylphenol polyoxyethylene ether is dissolved in water and prepared into solutions with different mass fractions for later use. The method is to prepare 8 parts of the alkylphenol polyoxyethylene ether solution, non-ionic polyoxyethylene (Vinyl acetate-ethylene) copolymer emulsion 5 parts, after mixing evenly, spray it evenly on the sandy soil surface with a salt content of 3%, and after the mixture is naturally air-dried, a layer with good pressure resistance and excellent wind erosion resistance is formed The consolidation layer of the effect.

Embodiment 3

[0040] The fatty alcohol polyoxyethylene ether is dissolved in water and prepared into solutions with different mass fractions for later use. The method is prepared by 15 parts of fatty alcohol polyoxyethylene ether solution, nonionic poly(acetic acid 4 parts of vinyl ester-ethylene) copolymer emulsion, after mixing evenly, spray it evenly on the sandy soil surface with a salt content of about 3%, and form a layer after the mixture is naturally air-dried, which has good pressure bearing and excellent wind erosion resistance effect the consolidation layer.

Abstract

Disclosed is a sand stabilizing agent for a high-saline-alkaline-content desert. The sand stabilizing agent is a composition mixed by 5-25 parts of a solution of a nonionic surfactant with the concentration being 0.5-5.0% and 1-8 parts of a sand stabilizing emulsion with the concentration being 30-40%. The sand stabilizing agent is uniformly sprayed on a sandy oil surface having a salt content about 3% to form a mixture, and the mixture forms a high-strength saline-alkaline-resisting solidification layer after subjected to natural air-drying. The sand stabilizing agent has an excellent adhesive property of the high-saline-alkaline-content desert, and is good in wind erosion resistance, and don't cause environment pollution. Evaporation of water in the desert is reduced, and the growth of sandy oil microorganism is not affected. The sand stabilizing agent has advantages of low production cost, simple preparation, and application of mass sand stabilization, and is suitable for preventing and curing desertification of a high-saline-alkaline-content land.

Description

1. Technical field [0001] The invention relates to a sand-fixing agent for deserts, in particular to a sand-fixing agent for high-saline deserts. 2. Technical Background [0002] As an extremely important environmental and social problem, saline-alkali desertification is plaguing the world today and threatening the survival and development of human beings. All countries in the world regard the control of saline-alkali desertification as an important issue for ecological environment construction and sustainable development. [0003] The study on the improvement of saline-alkali land in foreign countries was earlier. Scholars in the United States, the former Soviet Union, Australia, Israel, Japan and other countries began to study soil salinization in the 1930s. Scholars in the former Soviet Union had a heated debate on whether to use artificial drainage to prevent secondary salinization of soil: scholars represented by B.A. Scholars represented by Fuda suggested that the con...
