Aluminum sulfate has a very good application in papermaking, water purification and other aspects. In the production, many used bauxite for production, but it is easy to cause the consumption of raw materials and the quality of the produced products. It will also be affected to a certain extent. Among various methods, only using kaolin as raw material for production is cost-effective, and the production process is relatively stable, and the quality of the produced products is relatively good.
The production process with kaolin as raw material is mainly divided into 4 steps:
1. The reaction equation of kaolin calcination process:
The purpose of the calcination process is to activate, use calcination to remove the OH in the alumina octahedron of kaolin, change the coordination number of aluminum from 6 to 5 or 4, and make the original ordered structure of kaolin into disorder. Structure of kaolin to obtain activity. From a thermodynamic point of view, temperature is the key factor that determines whether the reaction can proceed, so the main problem of activation is to control the calcination temperature. If the temperature is too high, the kaolin will become petrochemical, and its activity will be greatly reduced or even disappear; if the temperature is too low, it will not proceed. Dehydration or too little dehydration results in inactive kaolin or too low activity to achieve the purpose, and the effect of producing aluminum sulfate is not good.
2. The reaction equation of acid decomposition kaolin and acid decomposition process:
The decomposition reaction is the key point of production. In order to speed up the reaction and completely decompose, it is necessary to add excess sulfuric acid to carry out the reaction. The dissolution rate of aluminum is the main indicator of whether the reaction is complete, and it is also the key to ensure the quality of aluminum sulfate and reduce production costs. The essential.
3. Filtration uses a plate filter to separate the solution from other solid impurities.
4. Concentrated crystallization The excess water is evaporated by concentration, and the corresponding crystal water products are prepared by crystallization.
Introduced above is the technological process of using kaolin as raw material to produce aluminum sulfate. It is a method that has advantages in various production methods such as cost, quality and environmental protection, so it is now also used by major manufacturers. .
