Tip: Adhere to the proper usage guidelines for calcium aluminate powder—a water treatment agent—and master these six key points to achieve twice the result with half the effort! To help everyone make better use of calcium aluminate powder as a water treatment agent and enjoy an even better user experience, please take note of the following six common questions:
1. Explosion-proof drying: Prolonged exposure to sunlight can also cause damage to express packages. To prevent damage during transportation and storage, strictly avoid mixed storage. Generally, do not mix this material with other types of concrete, lime powder, or other cementitious chemical substances that can release calcium hydroxide.
2. Waterproofing: Since there is relatively more rainfall in summer, calcium aluminate powder is very prone to absorbing moisture, which can negatively affect the user experience. If the calcium aluminate powder becomes clumped due to moisture absorption, it must be broken down and ground into a fine powder. Any clumps that are difficult to crush should definitely be discarded and not used.
3. During the use of calcium aluminate powder as a water treatment agent, it is essential to prepare the acid-soluble concentration appropriately to prevent the precipitation of silica rubber deposits.
4. During the use of calcium aluminate powder as a water treatment agent, the feed rate must be even and not too fast. Before starting the production process for polyaluminum chloride using calcium aluminate powder as a water treatment agent, first fill the reaction tank with water and turn on the agitator. Then, add sulfuric acid in a measured amount, dilute it to the specified concentration, and gradually add the calcium aluminate powder to initiate the reaction.
5. During the chemical reaction process of calcium aluminate powder used as a water treatment agent, the ambient temperature in the tank will gradually rise. When the temperature exceeds 110℃, water can be appropriately released to help moderate the reaction and prevent it from becoming too vigorous and overflowing the tank. Water should be replenished in small amounts at frequent intervals to maintain the normal required ambient temperature.
6. Add calcium aluminate powder until the mixture is fully saturated, then allow it to react for another 2 hours. Once the pH test indicates a value exceeding 3, dilute the mixture with water to achieve a specific gravity of 1.25–1.26. After feeding the resulting slurry into the sedimentation tank for settling, the clear supernatant liquid obtained is the liquid commercial product. Alternatively, the supernatant can be dried in a dryer to produce solid polyaluminum chloride.
Xintai Group Company: What is the raw material for calcium aluminate powder used as a water treatment agent?
At this stage, calcium aluminate powder—a water treatment agent—is the raw material most commonly used by polyaluminum chloride manufacturers in the market. As a result, some friends may have this concern: What exactly is the raw material for calcium aluminate powder used as a water treatment agent? And what are its key features and advantages? Here, our editor will answer these questions one by one for you!
Calcium aluminate powder is a specialized raw material used in the production of polyaluminum chloride—a water treatment agent—made from high-quality bauxite and dolomite that undergo crushing, drying, ball milling, billet formation, firing, and cement grinding. This industrial product appears grayish-white and is slightly soluble in water; its aqueous solution has an alkaline pH of approximately 11.
What are the advantages and characteristics of calcium aluminate powder, a water treatment agent, as a raw material for the production of polyaluminum chloride?
1. It generates low heat, has a high sodium bisulfate content and a low calcium hydroxide content, enabling the production of solid polyaluminum chloride with a sodium bisulfate content exceeding 30%.
2. Acid consumption is reduced, and costs have dropped significantly, overcoming a major challenge in the production of sodium bisulfate—namely, the inability of calcium aluminate to directly produce aggregated aluminum products with a concentration exceeding 30%.
3. Calcium aluminate powder exhibits extremely high reactivity when reacting with strong alkaline inorganic substances, and the reaction can proceed even at room temperature.
4. Calcium aluminate powder generates significant heat and heats up rapidly. The leaching rate of aluminum oxide can reach over 90%. When used as a raw material to produce liquid or solid polyaluminum chloride, it can optimize the manufacturing process, reduce costs, and improve product quality. It is currently the raw material most widely used by polyaluminum chloride manufacturers around the world.
