Description

TECHNICAL FIELD

[0001] The present application relates to a production technology of antimony pentoxide colloid, in particular to a continuous production method and equipment for preparing antimony pentoxide. BACKGROUND

[0002] As an important inorganic compound, antimony pentoxide has a wide range of applications in various fields. For example, in the flame retardant industry, it can effectively improve the flame retardant performance of materials and ensure safety in use; in the catalyst field, it can be used as a catalyst or catalyst carrier for various chemical reactions to promote the reaction; in the glass manufacturing industry, it can improve the optical performance and chemical stability of glass. Therefore, efficient and stable preparation of antimony pentoxide has important economic value and practical significance.

[0003] Currently, the commonly used method is to mix antimony trioxide solution with a stabilizer, then add hydrogen peroxide solution and heat to make the antimony trioxide solution react with the hydrogen peroxide solution to produce antimony pentoxide colloid, and then stabilize the produced colloid with the stabilizer. This preparation method has some deficiencies in the preparation process, which seriously restricts the production efficiency and product quality of antimony pentoxide.

[0004] For example, in the aspect of raw material mixing, a simple mixing method is usually used, which leads to uneven mixing of raw materials, resulting in poor production reaction effect. At the same time, the heating process is also a big bottleneck of existing preparation technology. The traditional heating method often cannot heat the reaction raw materials sufficiently and uniformly, which easily causes local overheating. Local overheating can cause a series of adverse consequences. On the one hand, it may cause decomposition and other side reactions of raw materials, producing unnecessary by-products and reducing the yield of target product antimony pentoxide; on the other hand, uneven heating will lead to uneven temperature distribution in the reaction system, affecting the reaction rate and equilibrium, making the reaction difficult to proceed under ideal conditions, and finally leading to unstable product quality. For example, in some preparation methods that directly heat the reaction container, the temperature difference between the edge and center of the container is large, resulting in uneven size of the generated antimony pentoxide particles and obvious performance difference.

[0005] In addition, most of the existing preparation methods are batch production, which has obvious limitations. Batch production needs to stop the reaction after each production cycle, perform product collection, equipment cleaning and other operations, and then start the production of the next cycle. This not only leads to low production efficiency and increases production cost, but also makes it difficult to realize large-scale and continuous production.

[0006] In summary, the preparation method and equipment of antimony pentoxide in the prior art have many deficiencies in raw material mixing, heating, production mode and the like, and it is difficult to meet the market demand for efficient and stable production of antimony pentoxide. Therefore, it has important practical significance to develop a preparation method and equipment of antimony pentoxide which can accurately control the uniform mixing of raw materials, realize uniform heating, continuous production and have efficient automatic filtering function.
