Problems solved by technology

Due to the high temperature of the desert surface, it is reported that it can reach above 65°C, and the polymer sand-fixing and dust-suppressing agent has poor temperature resistance, will quickly decompose and lose its effect, and has a short service life; inorganic adhesives cannot provide vegetation. necessary nutrients, and the alkaline dust suppressant destroys the pH value of the surface and destroys the growth of vegetation

Abstract

The invention provides a sand-fixing and dust-suppressing agent, a sand-fixing and dust-suppressing method and a desert improvement method. The sand-fixing and dust-suppressing agent comprises the following two components: a component A which comprises water glass, starch, a surfactant and water; and a component B which is an acid solution curing neutralizer. According to the sand-fixing and dust-suppressing agent, the sand-fixing and dust-suppressing method and the desert improvement method provided by the invention, the sand-fixing and dust-suppressing agent has characteristics of rapid consolidation, neutrality, temperature resistance and long duration period, and a tough solidified layer can be formed; and the solidified layer can exerts effects of preventing wind erosion, fixing sandand suppressing dust, can maintain underground moisture, also can provide nutrients needed for growth of vegetation, and can improve a desert environment.

Description

technical field [0001] The invention relates to a sand-fixing and dust-suppressing agent, in particular to a sand-fixing and dust-suppressing method and a desert improving method. Background technique [0002] Some desertified areas lack vegetation protection, and the phenomenon of sand and dust is relatively serious. Research and practice in recent years have shown that chemical dust suppression methods are more effective in sand fixation and dust suppression. [0003] At present, the development and application of sand-fixing and dust-suppressing agents are developing rapidly, and there are many varieties, mainly including high molecular polymers and inorganic adhesives. Carboxymethyl starch, melamine urea-formaldehyde resin, carboxymethyl cellulose, polyacrylate, sodium polyacrylate, sodium carboxymethyl cellulose, polyether glycol, polyvinyl alcohol, oxidized starch, etc. Graft acrylic acid acrylamide, vinyl acetate, methyl methacrylate and butyl acrylate terpolymer, e...
