Abstract

The invention discloses a water-soluble chemical fertilizer anti-caking agent as well as a preparation method and a use method thereof. The water-soluble chemical fertilizer anti-caking agent is prepared from the following components in percentage by mass: 1.4-6% of polyvinyl alcohol, 7-12% of a dispersing agent, 10-20% of an anionic surfactant, 20-26% of glycerol or anhydrous glycerin, 0.01-0.1% of a defoaming agent and the balance of water. The anti-caking agent prepared by the invention is good in water solubility, can be sprayed on a chemical fertilizer, is convenient to use, simple to operate and small in dosage, and can adapt to southern and northern climates at the same time.

Description

technical field [0001] The invention belongs to the field of chemical fertilizer additives, and in particular relates to a water-soluble chemical fertilizer anticaking agent and a preparation method and application method thereof. Background technique [0002] Fertilizer caking is a problem that the fertilizer industry has been working on for a long time. The agglomeration of chemical fertilizers seriously affects the fertilizer efficiency and brings many difficulties to storage, transportation and use. For example, agglomerated ammonium bicarbonate is easily broken during transportation, and if it is stored at a temperature of 26°C to 28°C for 10 days, the loss of nitrogen can reach 75.4%. Serious agglomeration of chemical fertilizers is difficult to break, partial agglomeration of chemical fertilizers is not good for mechanical fertilization, and small pieces of chemical fertilizers are easy to block nozzles, which bring inconvenience to fertilization. Therefore, solving...
