Problems solved by technology

However, the existing solution can ensure that the potash fertilizer granules are not powdered by extruding and adding a binder in a short period of time, but after placing and transporting, the bonding effect will decrease, and deliquescence will occur, and the dust will increase (dust greater than 0.5%) Phenomenon, the strength decreases, and the binder will affect the dissolution of the product. After a period of time, it will not dissolve for a few days, affecting the quality and use effect of potassium particles.

Embodiment 1

[0022] Select 1 kg of extruded potash fertilizer granules, heat them to 70 degrees in the drum device, choose 1 part of water-soluble paint urea-formaldehyde, mix with 0.5 parts of water, and mix 0.1 part of talc powder, feed according to 1% of the material, and coat in the drum Heat for 10 minutes. The dust rate after coating is less than 0.05%.

Embodiment 2

[0024] Select 1 kg of extruded potassium fertilizer granules, heat them to 40 degrees in the drum device, choose 1 part of water-soluble paint urea-formaldehyde, mix 2 parts of water, and 0.5 part of talcum powder, feed according to 0.5% of the material, and coat in the drum Heat for 10 minutes. The dust rate after coating is less than 0.05%.

Embodiment 3

[0026] Select 1 kg of extruded potassium fertilizer granules, heat them to 80 degrees in the drum device, choose 1 part of water-soluble paint urea-formaldehyde, mix 2 parts of water, and 1.5 parts of talcum powder, and feed according to 1.5% of the material, and coat in the drum Heat for 8 minutes. The dust rate after coating is less than 0.05%.

Abstract

The present invention discloses an additive for preventing a potassium fertilizer from powder generation, and an application method thereof, and belongs to the technical field of fertilizers. The additive comprises, by weight, 0.5-10 parts of a urea-formaldehyde resin, 0.2-15 parts of water, and 0.05-1.5 parts of talc powder. According to the present invention, based on the particle extrusion, the urea-formaldehyde water-soluble material is coated on the extruded particle surface to form the film on the particle surface, such that the effects of damage resistance, moisture resistance, and powder generation prevention are provided; and the additive has characteristics of low cost, simple process, easy operation, strong expansion, safety, and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an anti-pollination additive for potassium fertilizers and an application method thereof. Background technique [0002] Potassium fertilizer is difficult to granulate due to its own characteristics, and extrusion or bonded granulation is mostly used. Extrusion granulation refers to increasing the extrusion force; cohesive granulation refers to adding a cementing agent to play a bonding role to prevent powder from extruding potassium granules. However, the existing solution can ensure that the potash fertilizer granules are not powdered by extruding and adding a binder in a short period of time, but after placing and transporting, the bonding effect will decrease, and deliquescence will occur, and the dust will increase (dust greater than 0.5%) Phenomenon, the strength decreases, and the binder will affect the dissolution of the product. After a period of time, it...
