Problems solved by technology

The "hair growth" phenomenon of compound fertilizer seriously affects the appearance of the fertilizer. When farmers use it, the sensory perception is even more affected.
This also caused a large number of dealers to return and exchange goods, causing a lot of economic losses to fertilizer production enterprises.
Therefore, the "long hair" of fertilizers has seriously restricted the economic development of chemical fertilizer enterprises, and finding a solution is also an urgent problem for chemical fertilizer production enterprises to solve

Embodiment 1-8

[0035] Embodiment 1-8 is prepared according to the following method:

[0036] 1. Weigh the water control agent and thickener according to the above ratio, mix and pulverize them with Raymond mill or ball mill to more than 300 mesh, and obtain mixture A;

[0037] 2. Pulverize the urease inhibitor, nitrification inhibitor, water-absorbent resin, and preservative to more than 800 meshes with a jet mill according to the above ratio, and prepare mixture B;

[0038] 3. Add the mixture A prepared in step 1 and the mixture B prepared in step 2 into the mixer, and stir evenly to obtain an additive for preventing compound fertilizer from whitening and powdering.

[0039] Examples 9-16 were prepared according to the following method: all the raw materials were weighed according to the above ratio, and crushed with a jet mill to more than 800 meshes to obtain an additive for preventing compound fertilizer from whitening and pulverization.

Embodiment 17

[0041] The application of the additives used to prevent compound fertilizer from whitening and pulverization in this embodiment is to use the products of Examples 1-4 in the feeding section of the compound fertilizer production process, mix and add together with the compound fertilizer raw materials, and granulate In-machine granulation, the amount of fertilizer added is 9kg / ton, the fertilizer formula is 18-18-18, black organic-inorganic fertilizer, the fertilizer has no whitening and pulverization phenomenon after 6 months after adding, and the same fertilizer that is not added, No. The phenomenon of whitening occurs in 2 days, and the phenomenon of chalking occurs in 3 months.

Embodiment 18

[0043] The application of the additives used to prevent compound fertilizer from whitening and pulverization in this embodiment is to use the products of Examples 5-8 in the return section of the compound fertilizer production process, and mix together with the return material of the compound fertilizer into granulation In-machine granulation, the amount of fertilizer added is 16kg / ton, the fertilizer formula is 17-23-5, green, there is no whitening and pulverization of the fertilizer after 6 months after adding, and compared with the fertilizer without adding, the fertilizer without adding After 7 days, the surface of the fertilizer turns white, and the appearance has a sense of fading, and powdering occurs after 2 months.

Abstract

The invention provides to an additive for preventing whitening and efflorescence of composite fertilizer, and a preparation method and an application thereof, relates to a chemical fertilizer additive, and especially relates to an additive for preventing whitening and efflorescence. The additive for preventing whitening and efflorescence of the composite fertilizer comprises, by mass, 1-10 parts of a urease inhibitor, 1-10 parts of a nitration inhibitor, 50-90 parts of a water controller, 10-50 parts of water absorbent resin, 1-5 parts of an antiseptic and 1-10 parts of a thickening agent. The preparation method comprises the steps of crushing above raw materials, and uniformly mixing the crushed raw materials. The additive for preventing whitening and efflorescence of the composite fertilizer is convenient and simple to use, and can be directly used without any devices; and the additive can be added to the composite fertilizer to realize a good whitening prevention effect, and can enhance the particle strength and improve the easy efflorescence condition of the fertilizer. The preparation method is used in the field of chemical fertilizer additives.

Description

technical field [0001] The invention relates to a chemical fertilizer additive, in particular to an additive for preventing compound fertilizer from whitening and powdering. Background technique [0002] The surface of compound fertilizer particles is easy to grow some radial shape, straight, thick and thin like hair or catkins, feather-like translucent crystals, touch and break into powder by hand, sometimes dissolve quickly on the hand, commonly known as "long hair" Phenomenon. However, "whitening", "long hair" and "powdering" can be regarded as different stages of "long hair". Especially the dark color fertilizer is obvious; "powdering" is in the later stage, due to internal and external influences, the "long hair" is continuously broken and pulverization is formed. [0003] In the fertilizer market, the phenomenon of "whitening", "long hair" and "powdering" (hereinafter referred to as "long hair") of compound fertilizers is often encountered. The "long hair" of compoun...
