How to Identify High-Quality Slaked Lime Powder
Slaked lime, also known as calcium hydroxide, is widely used in construction, agriculture, and various industrial applications. However, not all slaked lime powder is of the same quality. Here’s a step-by-step guide to help you identify high-quality slaked lime powder for your needs. 1. Check the Purity The first indicator of high-quality slaked lime powder is its purity. The best slaked lime has a high percentage of calcium hydroxide, typically above 90%. Impurities such as magnesium, silica, and iron should be minimal. Checking the chemical composition on the packaging or requesting a laboratory test can help determine purity. 2. Examine the Color and Texture High-quality slaked lime should be white and finely powdered. A dull or greyish color may indicate impurities. The texture should be smooth and soft, without visible lumps, which ensures proper reactivity and performance in applications. 3. Perform the Water Reactivity Test To test reactivity, mix a small amou...
