Manufacturing method
of diammonium phosphate
diammonium phosphate is a widely used chemical product, mainly used as fertilizer and food additive. Its manufacturing process involves multiple steps, including reaction, crystallization, drying, and packaging. This article will introduce the manufacturing method of diammonium phosphate in detail.

1. Raw Material Preparation

The main raw materials for the manufacture of diammonium phosphate are phosphoric acid and ammonia. Phosphoric acid can be obtained by acid hydrolysis of phosphate rock, while ammonia is usually obtained from ammonia synthesis plants. Both raw materials need to reach a certain purity before they can be used in production.

2. reaction process

1. neutralization reaction: phosphoric acid and ammonia mixed in a certain proportion, the neutralization reaction to generate ammonium phosphate. This reaction is exothermic and the reaction temperature needs to be controlled to avoid material loss.
2. Reaction of monoammonium phosphate with ammonia: Monoammonium phosphate reacts with excess ammonia to produce diammonium phosphate. This step of the reaction also requires temperature and time control to ensure complete reaction. The diammonium phosphate solution generated
the
reaction of the

3. crystallization process needs to go through the crystallization process to obtain a higher purity product. During the crystallization process, temperature and stirring speed need to be controlled to promote crystal growth and precipitation. DAP

4. Drying and Packing

Crystallization The DAP wet material is dried to remove excess water. The dried product needs to be packaged for storage and transportation.

above is the basic manufacturing process of diammonium phosphate, and the specific operation will vary according to different production equipment and process conditions. In order to ensure the quality and output of the product, it is necessary to strictly control the parameters of each step in the production process, such as temperature, pressure, and material ratio.

In addition, the production of diammonium phosphate also needs to consider environmental protection and safety issues. Exhaust gas, waste water and solid waste generated in the production process need to be properly treated to avoid impact on the environment and human health. At the same time, production equipment and operating processes also need to comply with relevant safety regulations to ensure the personal safety of employees.

In short, the manufacturing process of diammonium phosphate involves the control of multiple links and parameters, and requires rigorous operation and management to ensure product quality and output. At the same time, environmental protection and safety issues also need to be fully valued and dealt with to ensure the sustainability of production and the physical and mental health of employees.
