Problems solved by technology

The inventor found that: the main component of the anti-caking agent is a crystallization agent of some inorganic salts, the addition amount is 5-10%, and it is added in the slurry before the crystallization of monoammonium phosphate; and the phosphoric acid proposed in this patent document The monoammonium anti-caking agent is only for the monoammonium phosphate of the slurry method, and its addition amount is relatively large, so it is not suitable for use on the industrial monoammonium phosphate with higher product quality and purity

Abstract

The invention belongs to the technical field of anticaking agents, and particularly relates to a crystalline industrial monoammonium phosphate anticaking agent and a preparation method and use methodthereof. The anticaking agent comprises the following raw materials: 15-40wt% of a crystal control agent, 10-25wt% of a lubricating agent, 10-25wt% of diluent, 20-35wt% of stabilizer and 20-35wt% of an anti-blushing agent. The use method comprises the following steps of spraying the water agent on the crystallized industrial monoammonium phosphate, stirring well, spraying powder and stirring wellagain. The liquid component in the anticaking agent is in liquid state at normal temperature, can be directly used, and greatly saves manpower, material resources and energy consumption. In addition,the anticaking agent is directly used in crystallized industrial monoammonium phosphate crystals instead of being added in industrial monoammonium phosphate slurry before crystallization, thereby effectively solving the problems of low production efficiency, low product purity and abnormal monoammonium crystals caused by the addition of the anticaking agent in the slurry.

Description

technical field [0001] The invention belongs to the technical field of anti-caking agents, in particular to a crystalline industrial monoammonium phosphate anti-caking agent and its preparation and use method. Background technique [0002] In the present invention, the information disclosed in the background art is only intended to increase the understanding of the general background of the present invention, and is not necessarily regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art known to those skilled in the art . [0003] Crystalline industrial monoammonium phosphate (that is, the industrial monoammonium phosphate described below) is widely used in industry and is a good flame retardant. It can also be used as a dispersant in the dye industry, a glaze for enamel, a compounding agent for fireproof coatings, and a dry powder fire extinguishing agent. It can also be used as a feed additive, and it is also used in the phar...
