Read： 447 Time：20months ago Source：Transform the World with Simplicity

Urea phosphate is an important raw material for chemical production, which is widely used in agriculture, medicine, daily chemical and other fields. This article will introduce the manufacturing method of urea phosphate, including raw material preparation, reaction process, post-treatment and other steps.

1. Raw Material Preparation

1. Urea: Urea is one of the main raw materials for urea phosphate production and is used to react with phosphoric acid to generate urea phosphate.
2. Phosphoric acid: Phosphoric acid is another important raw material that reacts with urea to form urea phosphate.

2. reaction process

1. add urea and phosphoric acid into the reactor according to a certain molar ratio and stir evenly.
2. At a certain temperature, urea and phosphoric acid react to form urea phosphate and water.
3. Control the reaction temperature and time to ensure that the reaction proceeds to completion.
4. The pH of the reaction solution is adjusted to the desired range.

3. post-treatment

1. the reaction solution is filtered to remove impurities and solid particles therein.
2. The filtrate was concentrated by evaporation to obtain a concentrated solution of urea phosphate.
3. The concentrated solution is subjected to cooling crystallization to obtain crystals of urea phosphate.
4. The urea phosphate crystals are subjected to centrifugal separation, drying and other treatments to obtain the final urea phosphate product.
Precautions for
4.

1. In the production process, it is necessary to strictly control the reaction temperature and time to ensure that the reaction is complete.
2. There are high requirements for the quality and purity of raw materials to ensure product quality.
3. In the post-processing process, it is necessary to pay attention to prevent the product from absorbing moisture and caking.

In short, the manufacturing method of urea phosphate requires strict control of the process parameters of each step to ensure product quality and production efficiency. At the same time, it is necessary to strengthen the safety management and environmental protection measures in the production process to ensure the smooth progress of the production process.
