Products Description
A moisture-proof silicon-magnesium composite granular fertilizer and a preparation method thereof. The composite granular fertilizer is prepared from the following raw materials in weight percentage: 2570% magnesium fertilizer, 1535% silicon fertilizer, 38% slow-release agent, 720% auxiliary agent 1, and 515% auxiliary agent 2. The magnesium fertilizer is selected from at least one of anhydrous magnesium sulfate, magnesium sulfate monohydrate, magnesium sulfate pentahydrate, and magnesium sulfate heptahydrate; the silicon fertilizer is selected from at least one of sodium silicate and sodium metasilicate; the slow-release agent is selected from at least one of sodium carboxymethyl cellulose and corn starch; the auxiliary agent 1 is a mixture of montmorillonite and white carbon black in a mass ratio of 18:1; the auxiliary agent 2 is a mixture of bentonite and magnesium stearate in a mass ratio of 14:1. The composite granular fertilizer can effectively prevent deliquescence, reduce the difficulty of fertilizer storage and the storage cost of fertilizer enterprises, and is suitable for mechanized application, thereby improving the application efficiency and fertilizer utilization rate of fertilizers.

Products cooperation picture
1.A new type of silicon-magnesium gel (MgO.1.19 SiO2) was synthesized by hydrothermal method with Na2SiO3·9H2O and MgCl2·6H2O as raw materials. Its structure before and after calcination was characterized by physical analysis methods such as BET, SEM, FT-IR, and XRD. At the same time, the effect of calcination temperature of silica-magnesium gel on the adsorption performance of basic magenta was studied. The results showed that silica-magnesium gel calcined at 700℃ (C-Mg-Si gel-700) had the best adsorption of basic magenta. The adsorption process conformed to the Langmuir isotherm adsorption model and pseudo-second-order kinetic equation, and the maximum equilibrium adsorption capacity was 598.95mg.g-1.
