Problems solved by technology

This also caused a large number of dealers to return and exchange goods, causing a lot of economic losses to the compound fertilizer production enterprises.
Therefore, the "long hair" and "powdering" of compound fertilizers have seriously restricted the economic development of chemical fertilizer enterprises, and thus become an urgent problem for chemical fertilizer production enterprises to solve

Embodiment 1

[0019] The addition amount of each component in the compound fertilizer anti-dusting agent of this embodiment is shown in Table 1.

[0020] Add the compound fertilizer anti-powdering agent of this embodiment directly to the compound fertilizer, and compare it with the compound fertilizer without treatment, respectively measure the particle strength and balling rate of the compound fertilizer, and observe the surface phenomenon of the particles. The results are shown in Table 1. The granule strength of the compound fertilizer is determined by SN / T0736.3-1997 Import and Export Fertilizer Inspection Method; the pelleting rate of the compound fertilizer is determined by sieving with a fineness sieve and weighing with an analytical balance.

Abstract

The invention discloses a compound fertilizer anti-pulverization agent and a use thereof, relates to a chemical fertilizer addition agent, and especially relates to a compound fertilizer anti-pulverization agent. The invention aims at providing the compound fertilizer anti-pulverization agent which has strong anti-pulverization ability and has the functions of increasing the balling rate of a compound fertilizer, reducing the cost of compound fertilizer materials, enhancing the strength of fertilizer particles, reducing the agglomeration rate of the fertilizer and improving the whiteness of the fertilizer. The compound fertilizer anti-pulverization agent comprises a water-soluble macromolecule resin and an inorganic salt with water absorption effect. The compound fertilizer anti-pulverization agent has the advantages of being strong in compound fertilizer pulverization ability, quickly increasing the balling rate of the compound fertilizer, reducing the cost of compound fertilizer materials, enhancing the strength of fertilizer particle, reducing the agglomeration rate of the fertilizer and improving the whiteness of the fertilizer. The compound fertilizer anti-pulverization agent is applied to field of chemical fertilizer additives.

Description

technical field [0001] The invention relates to a chemical fertilizer additive, in particular to an anti-dusting agent for compound fertilizer. Background technique [0002] The compound fertilizer grows some radial shape, straight, thick and thin like hair or catkin-like, feather-like translucent crystals on the particle surface, touch and break into powder by hand, and sometimes dissolve quickly on the hand, commonly known as "long hair". Phenomenon. And "whitening", "long hair" and "powdering" can be regarded as different stages of "long hair", "whitening" is the early stage, due to the influence of internal and external factors may not continue to change, for "whitening", Especially the dark-colored fertilizer looks very obvious; "chalking" is the later stage, and due to internal and external influences, the "long hair" is continuously broken and powdered. [0003] In the fertilizer market, the phenomenon of "whitening", "long hair" and "powdering" of compound fertiliz...
