Calcium aluminate powder has a remarkably wide range of applications and is used in many different settings. Although it boasts numerous advantages, it’s crucial to master the correct usage techniques when working with it. Only by doing so can you avoid any potential problems. Next, let’s take a closer look at how this product should be used. We hope this information will prove helpful to you.

There are quite a few key points you need to understand before using calcium aluminate powder. If you’re already familiar with its basics, then you’ll definitely want to read this article carefully. Calcium aluminate powder reacts with hydrochloric acid to produce polyaluminum chloride in a single step. When using this process, you’ll need to determine the appropriate weight of hydrochloric acid to add, as well as the corresponding weight of calcium aluminate powder. At this stage, it’s crucial that you know the expected degree of basicity for the polyaluminum chloride product. You’ll also need to consider the aluminum oxide content (%) in the calcium aluminate powder, the aluminum oxide content (%) in the calcium aluminate powder itself, the concentration of hydrochloric acid, and the leaching rate. These details might only be easily understood by professionals. During production, first add water to the reaction tank, start the agitator, and then add measured amounts of hydrochloric acid, diluting it to the required concentration. Throughout this process, you should gradually add the calcium aluminate powder while allowing the reaction to proceed. Additionally, during this reaction, you’ll notice that the temperature inside the tank will gradually rise. If you observe that the temperature exceeds 110°C, you can add a small amount of water to help control the temperature. This prevents the reaction from becoming too vigorous and causing overflow. Remember to add water in small increments several times rather than all at once. Only in this way can you maintain the optimal reaction temperature.

After adding the calcium aluminate powder, wait another two hours for the reaction to complete. Then, use a pH test strip to verify that the pH is greater than 3. At this point, you can dilute the mixture with water to achieve a density of 1.25–1.26. Once the material has been discharged and allowed to settle in the sedimentation tank, the clear supernatant liquid above the sediment is the liquid product. This liquid can then be dried in a dryer to obtain the solid polyaluminum chloride product. These are the key steps involved in the entire process. Therefore, when using calcium aluminate powder, you must exercise extra caution. We’d also like to remind you here about proper transportation and storage procedures: Our products are packaged in plastic woven bags, each weighing 50 ± 1 kg net. During transportation and storage, it’s crucial to keep the product dry, waterproof, and moisture-proof. If the powder clumps upon exposure to moisture, it must be properly treated before further use. That’s all for now on the topic of calcium aluminate powder.
