Abstract

The invention belongs to a chemical additive, and relates to an anti-caking additive with slow release effect. The anti-caking additive with slow release effect is mainly characterized in that organicmodifiers with a certain weight percentages such as hydrocarbon compounds, grease and the like are evenly mixed with powdered materials such as calcium silicate and fly ash at a certain temperature by a wet method, and subject to dehydration, drying and crushed into a powder product, and the product is evenly added to various granulated chemical fertilizers for use, the product prevents chemicalfertilizers from caking after adding the product to the fertilizers in package and storage. The anti-caking additive has slow release effect after fertilization, and enhances fertilizer efficiency. The anti-caking additives has advantages of no toxic and side effect, no pollution, low cost, less usage and better anti-caking performance compared with other like products and has certain slow releaseeffect on the fertilizers. The anti-caking additive is also applicable to anti-caking for other grain products.

Description

technical field [0001] The invention belongs to chemical additives, in particular to an anti-caking agent with slow-release effect. Background technique [0002] my country is a large agricultural country, and the amount and output of various chemical fertilizers are very large. However, chemical fertilizers are prone to moisture and agglomeration during storage, resulting in inconvenient use and waste, and even safety accidents. In other granulation industries, there are also situations where granule products are easy to agglomerate. [0003] The existing anti-caking technologies mainly include: ①During the production process of fertilizer granulation, surfactants are directly added to the raw materials, so that the fertilizer granules can be adsorbed to form a water-proof layer to prevent the particles from sticking together; ②Spray after granulation Liquid organic compound (such as paraffin), so that it is wrapped on the surface of the particles to form a water-proof la...
