Problems solved by technology

However, due to the influence of crystal shape, composition, structure, surface area, physical and chemical properties and surrounding storage environment, potassium nitrate is very easy to agglomerate, which brings difficulties to storage, transportation and use.
Potassium nitrate is a pseudo-agglomeration, and the agglomeration will break apart when pressure is applied, which brings trouble to the use process.

Embodiment 1

[0013] A method for preparing potassium nitrate fertilizer without false caking, comprising the following steps:

[0014] Step (1): Add 3% anti-caking agent to the finished potassium nitrate product just prepared, and mix the materials evenly;

[0015] Step (2): Pack the mixture prepared in step (1), put a desiccant bag into the bag, and then seal it with air suction.

[0016] The anti-caking agent is composed of 60 parts by weight of activated carbon powder, 10 parts by weight of superphosphate and 24 parts by weight of stearate.

[0017] Attapulgite is contained in the desiccant bag.

Embodiment 2

[0019] A method for preparing potassium nitrate fertilizer without false caking, comprising the following steps:

[0020] Step (1): Add 6% anti-caking agent to the finished potassium nitrate product just prepared, and mix the materials evenly;

[0021] Step (2): Pack the mixture prepared in step (1), put a desiccant bag into the bag, and then seal it with air suction.

[0022] The anti-caking agent is composed of 40 parts by weight of activated carbon powder, 15 parts by weight of superphosphate and 12 parts by weight of stearate.

[0023] Attapulgite is contained in the desiccant bag.

Embodiment 3

[0025] A method for preparing potassium nitrate fertilizer without false caking, comprising the following steps:

[0026] Step (1): Add 4.5% anti-caking agent to the finished potassium nitrate product just prepared, and mix the materials evenly;

[0027] Step (2): Pack the mixture prepared in step (1), put a desiccant bag into the bag, and then seal it with air suction.

[0028] The anti-caking agent is composed of 50 parts by weight of activated carbon powder, 12 parts by weight of superphosphate and 18 parts by weight of stearate.

[0029] Attapulgite is contained in the desiccant bag.

Abstract

The invention discloses a preparation method of a potassium nitrate fertilizer without pseudo agglomerate. The method comprises the following steps: (1) adding 3-6% of an anti-blocking agent into finished potassium nitrate that is just completely prepared, and uniformly mixing the materials; (2) bagging and packaging the mixture prepared in the step (1), putting a drying agent package into the packaging bag, exhausting air and sealing. According to the preparation method of the potassium nitrate fertilizer disclosed in the invention, the characters of the prepared potassium nitrate can be improved, agglomeration is avoided, and trouble brought by material agglomeration in the using process of potassium nitrate can be saved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing potassium nitrate fertilizer without pseudo-caking. Background technique [0002] Potassium nitrate is an important fertilizer, containing N13.5% and K2O46%, and there is no residue after application. It is not only a high-quality fertilizer for chlorine-avoiding crops such as tobacco, coffee, tomato, grape, citrus, tea, etc. Potassium nitrate is not only high in potassium content, but also a nitrogen-potassium compound fertilizer with good water solubility, low acidity, and easy absorption by plants. It is suitable for any crop and any season, and has broad-spectrum applicability. However, due to the influence of crystal shape, composition, structure, surface area, physical and chemical properties and surrounding storage environment, potassium nitrate is very easy to agglomerate, which brings difficulties to storage, transportation and use. Potassium ...
