Embodiment

[0015] The main raw material for preparing mandilite fertilizer additives is natural mandilite mineral; NH 4 Cl solution; NaCl solution.

[0016] The chemical composition and process conditions for preparing hematilite fertilizer additives: use the natural hematilite ore of Guangxi resources as raw material, wash the raw ore, crush and process it to 60-120 mesh; use 10 grams of hematite, 1 mole of NH 4 100 moles of Cl solution; 10 grams of hematilite and 1 mole of NaCl solution of 100 moles were used to prepare ammonium and sodium hematilite, placed at room temperature for 8 hours, and washed until there was no chloride ion. The modified stilbene is added in a proportion of 10% and processed into chemical fertilizer.

[0017] Manufacturing process: washing → crushing → modification → finished product packaging

Abstract

The invention discloses a preparation method for chemical fertilizers addition agent with red stilbite, which comprises steps: 1. elutriating and smashing raw material to 60-120 items; 2. preparing separately ammonium-type and natrium-type stilbite with 10g stilbite and 100 mol 1M NH4Cl solution, and 10g stilbite and 100mol 1M NaCl solution; placing for eight hours at room temperature; clearing to remove chloride ion. The adsorption ability of the modified product to kalium increases 3~4 times. As addition agent, it can realize the fixing and release slowly to nitrogen, phosphor and kalium, improves fertilizer performance and soil environment.

Description

technical field [0001] The invention relates to a method for preparing chemical fertilizer additives by using stilbite. Background technique [0002] Stellerite is a mineral species in the pyroxene group, its chemical composition (%): SiO 2 58.76、Al 2 o 3 14.13, CaO8.80, K 2 O0.11, Na 2 O0.18, Fe 2 o 3 0.44, H 2 o + 16.87, H 2 O-1.25, its calculated chemical formula is (K 0.017 Na 0.042 Ca 1.73 ) 1.189 [Al 1.997Si7. 5i 7.0.5018 ]6.75H 2 O. Natural stilbene is a hydrous alkali metal or alkaline earth metal aluminosilicate mineral, a framework silicate composed of silicon-oxygen tetrahedrons and aluminum-oxygen tetrahedrons. The oxygen atom in the aluminum oxygen tetrahedron has a valency and is not saturated, and the entire aluminum oxygen tetrahedron is negatively charged, and the nearby positively charged cations such as K + 、Na + , Ca 2+ , Mg 2+ Such as alkali metal or alkaline earth metal ions to compensate for the balance. The open structure is con...
