The synthesis of salt-resistant emulsion and its application in ecological sand-fixing of high salt-affected sandy land

Abstract

For the first time, the salt-resistant emulsion was applied as an ecological sand-fixing material to enhance the sand-fixing ability in salty desert. This study started from the synthesis of the novel salt-resistant poly(vinyl acetate-dibutyl maleate-acyclic acid-sodium p-styrene sulphonate) copolymer emulsion. Then, the structure, composition and thermal property of the emulsion were characterised. The sand-fixing properties and ecological effect of the emulsion were evaluated. The experimental results showed that the emulsion has been successful synthesised and could be used as an ecological sand-fixing material. The related reason is that, first, the emulsion could significantly visibly enhance the sand-fixing ability in high saltaffected sand land. Second, the prepared emulsion had good thermal aging resistance and freeze-thaw stabilities to withstand the changes in the temperature of salty desert, and the test of the influence of the emulsion on the growth of microbe of sand showed a favourable ecological effect.

Experimental investigation of the strong stability, antibacterial and anti-inflammatory effect and high bioabsorbability of a perilla oil or linseed oil nanoemulsion system

“…In general, if the particles have a high negative or positive zeta potential, they will be stabilized in the dispersed phase due to the interaction with each other, and therefore, for the emulsion, a high negative or positive zeta potential means good stability. 39 Zeta potential is a measure of the strength of mutual repulsion or attraction between particles. The stability of a nanoemulsion is related to particle size and zeta potential.…”

Fiber-Reinforced Sand-Fixing Board Based on the Concept of “Sand Control with Sand”: Experimental Design, Testing, and Application

“…Research on the development and use of new sand-fixing materials has achieved remarkable results in China and abroad. In recent years, domestic research has mainly focused on chemical sand fixing, such as polymer materials, organic-inorganic composite materials, and modified waste plastic materials [9][10][11][12][13]. International researchers have conducted numerous studies on microbial soil modification [14][15][16], using microbial metabolic activities to induce or control a series of chemical reactions in the soil to improve the soil, thereby achieving sand fixation [17][18][19].…”

Cultural heritage protection via hybrid nanocomposite coating

“…The best way to prevent destruction is to prevent water penetration into the inner stone portions because the accumulation of water causes erosion of the stone [7]. Also, the ultraviolet waves of the sun [8] and chemical substances [9] damaged the materials that need protection. The consolidation and protection nanocomposite treatment should penetrate the internal weakness layer of decayed historical stone until it reaches the appropriate depth of the not eroded stone.…”
