Liquid water-soluble fertilizer containing alginic acid and its preparation method
By constructing a composite suspension stabilization system, and using a combination of stabilizing components such as polysaccharide thickeners, cellulose derivatives, and inorganic thixotropic agents in synergy with alginic acid, the problems of low-temperature crystallization, high-temperature stratification, and short storage period of alginic acid liquid water-soluble fertilizer were solved, achieving stability and long-term storage under extreme temperatures.

AI Technical Summary
Liquid water-soluble fertilizers containing alginic acid are prone to crystallization at low temperatures and separation at high temperatures, resulting in a short shelf life, poor stability, and reduced effectiveness.
By constructing a synergistic composite suspension stabilization system, a combination of polysaccharide thickeners, cellulose derivatives, inorganic thixotropic agents, and polymeric dispersants is used as stabilizing components. These components work synergistically with alginate to form a three-dimensional network structure, ensuring stability within the range of -5℃ to 54℃.
The product exhibits no crystallization at -5℃ and no stratification at 54℃. When sealed and stored at room temperature, it remains uniformly suspended for more than 12 months, demonstrating stable active ingredients. This solves the problems of low-temperature crystallization and high-temperature stratification, thus extending the product's shelf life.
