Xintai Group: Six Points to Note When Using Calcium Aluminate Powder as a Water Purifier
What precautions should be taken when using calcium aluminate powder as a water purifier? Master these six key points, and you’ll achieve twice the results with half the effort!
The editor from Xintai Group would like to remind you to pay attention to the following precautions when using calcium aluminate powder for water purifiers. Mastering these six points will help you achieve twice the result with half the effort! To help everyone make better use of this calcium aluminate powder and attain optimal performance, here are six important precautions:
1. Explosion-proof and sun-resistant: Prolonged exposure to sunlight can damage the packaging. During storage, ensure that the packaging remains undamaged and avoid mixing with other materials. Generally, do not mix this product with other types of cement, lime, or other cementitious materials that can release calcium hydroxide.
2. Moisture resistance: Due to the heavy rainfall in summer, calcium aluminate powder is prone to moisture absorption, which can affect its performance. If the calcium aluminate powder becomes damp and clumpy, crush and grind it. If the hardened lumps are difficult to break down, discard them.
3. The editor of Xintai Group would like to inform everyone that when using calcium aluminate powder as a water purifier, it’s important to appropriately adjust the acid-soluble concentration to prevent silica gel flocs from settling.
4. The editor from Xintai Group would like to remind you that during the use of calcium aluminate powder, the addition of materials should be even and the feeding rate should not be too fast. In the process of producing polyaluminum chloride using calcium aluminate powder as a water purification agent, first add water into the reaction tank, then start stirring the slurry, followed by adding hydrochloric acid in a measured amount and diluting it to the desired concentration. Then, slowly add the calcium aluminate powder to initiate the reaction.
5. During the reaction process in which calcium aluminate powder is used as a water purifier, the temperature inside the tank will gradually rise. When the temperature exceeds 110°C, an appropriate amount of water can be added to inhibit the reaction and prevent it from becoming too vigorous and causing overflow. Add water several times, maintaining the temperature at the level required for normal operation.
6. After adding calcium aluminate powder, continue the reaction for another 2 hours. When the pH test paper reading exceeds 3, dilute the mixture with water to achieve a density of 1.25–1.26. Then, discharge the mixture into a sedimentation tank for settling; the supernatant liquid obtained is the liquid product. Alternatively, the supernatant can be dried in a dryer to produce solid polyaluminum chloride.
Xintai Group: How long is the shelf life of calcium aluminate powder when used as a water purification agent?
How long is the shelf life of calcium aluminate powder when used as a water purifier? When purchasing calcium aluminate powder for water purifiers, some customers ask about its shelf life. Here, the editor from Xintai Group will answer your question!
Answer: The calcium aluminate powder used in water purifiers has a shelf life of one year when properly packaged. During transportation and storage, it should be kept dry, waterproof, and moisture-free. If the powder becomes clumped due to exposure to water, it should be treated before use. Proper usage and storage will ensure that the product delivers its intended performance.
Calcium aluminate powder is a series of inorganic compounds produced by sintering aluminum oxide and calcium oxide at high temperatures. It exhibits strong activated carbon properties. Using an acid-soluble method to produce water purification agents can significantly save labor, electricity, and costs, and boasts the advantages of simple process equipment and ease of operation. Currently, calcium aluminate powder is an ideal raw material for the production of basic aluminum chloride and polyaluminum chloride products.
Next, Xintai Group will discuss the key performance characteristics of calcium aluminate powder used as a water treatment agent:
1. With low heat release, high aluminum chloride content, and low calcium oxide content, it is possible to produce solid polyaluminum chloride with an aluminum chloride content exceeding 30%.
2. This approach has significantly reduced acid consumption and lowered costs, effectively addressing the issue that calcium aluminate cannot directly produce polyaluminum chloride products with a polymerization degree exceeding 30%.
That’s all for today’s explanation from the Xintai Group editor. We hope it has been helpful to everyone. Thank you for watching!
