Problems solved by technology

However, most of the water storage materials made of water-absorbent resin are in the form of flocs and powders, and the specific gravity is also very light. If the water storage materials are directly applied in the field, it will consume a lot of human resources, which is very uneconomical and effective. poor method
[0004] Use the existing fertilizer granules and water-absorbent resin materials to manufacture water-storage fertilizers. Since the water-storage materials themselves are flocculent elastomers, they cannot be combined with fertilizer granules to form new products.
Therefore there is no report about the water storage fertilizer

Embodiment 1

[0032] Add 0.15kg of water storage material diapers and 0.15kg of potassium polyacrylate into the water storage material pretreatment machine and mix evenly for later use, add 99.6kg of urea granules into the disc coating machine, and coat the polyacrylate emulsion adhesive under the condition of rotation Spread on the surface of fertilizer granules. After the coating is completed, add spare water storage materials to the surface of fertilizer granules in the disc coating machine, and complete the coating on the surface of the granules under the condition of rotating and tumbling of the coating machine. The 100kg product granule made in this way has the function of chemical fertilizer and the function of water absorption and water retention simultaneously.

Embodiment 2

[0034] Add 0.2kg of water storage material diapers into the pretreatment machine and mix evenly for later use. Add 99.2kg of diammonium phosphate and 0.5kg of magnesium sulfate granules into the disc coating machine, and put polyethylene-vinyl acetate (EVA) under rotating conditions. ) The adhesive is coated on the surface of the fertilizer granules, and after the coating is completed, add a spare water storage material to the surface of the fertilizer granules in the disc coating machine, and complete the coating of the particle surface under the condition of the coating machine rotating and tumbling. The 100kg product granule made in this way has the function of chemical fertilizer and the function of water absorption and water retention simultaneously.

Embodiment 3

[0036] Add 0.3kg of potassium polyacrylate, a water storage material, into the pretreatment machine and mix evenly for later use. Add 99.4kg of compound fertilizer, 0.1kg of synergist and 0.1kg of borax granules into the drum coating machine, and put the polyacrylate under rotation. The emulsion adhesive is coated on the surface of the fertilizer granules. After the coating is completed, the spare water storage material is added to the surface of the fertilizer granules to the drum coating machine, and the coating on the surface of the granules is completed under the condition of the coating machine rotating and tumbling. The 100kg product granule made in this way has the function of chemical fertilizer and the function of water absorption and water retention simultaneously.

Abstract

The invention provides a water-holding fertilizer manufacturing method and a water-holding fertilizer product. In the method, a water-holding fertilizer is prepared by mixing water-holding materials for producing the water-holding fertilizer in a preprocessor and by mixing fertilizer particles in a coating machine and coating water-holding material films on the fertilizer particles. The invention belongs to a novel manufacturing process and novel product of water-holding fertilizer.

Description

technical field [0001] The invention relates to agricultural water storage materials and fertilizers, in particular to a manufacturing method and product of a novel water storage fertilizer. Background technique [0002] Various fertilizers are widely used in agricultural production, mainly elemental fertilizers such as urea, ammonium sulfate, potassium chloride, heavy calcium, etc., and multi-component compound fertilizers containing nitrogen, phosphorus, potassium and other nutrients. They are all granular fertilizers made through certain processes and equipment. They can provide various nutrients for plant growth. It has also contributed to the increase in production and income of farmers. But the growth of plants is inseparable from sunlight and water in addition to fertilizer nutrients. Especially in arid areas with little precipitation, it is not news to us that crops have been greatly reduced or lost due to lack of water. If we can provide fertilizer nutrients for ...
