Product type
Hydrated lime, also known as calcium hydroxide, is a white powder produced by adding water to quicklime (calcium oxide). This process, called slaking, results in a fine, dry powder that is highly alkaline. Hydrated lime is commonly used in various industrial applications due to its chemical properties, such as its ability to neutralize acidity and its effectiveness as a flocculant in water treatment processes.
| Chemical formula | Ca(OH)2 |
| Purity | Typically 90% to 95% calcium hydroxide |
| Particle size | Usually 90% passing through a 200 mesh screen |
| pH level | Typically 12.4 to 12.6 in solution |
| Moisture content | Generally less than 5% |
When selecting hydrated lime, consider the required purity level and particle size for your application. It's essential to specify the intended use, as different industries may have specific standards or certifications. Additionally, request information on moisture content and pH levels. Quantities can vary widely based on your project needs, so be clear about your order volume when requesting a quote.
