mészoldásnak

Mészoldásnak, also known as milk of lime or calcium hydroxide slurry, is a suspension of calcium hydroxide in water. It is typically prepared by adding slaked lime (calcium hydroxide) to water, which causes it to disperse and form a milky white liquid. The concentration of calcium hydroxide in mészoldásnak can vary depending on the intended application, but it generally ranges from 5% to 20% by weight.

The primary use of mészoldásnak is in water treatment and wastewater purification. It acts as a neutralizing agent for acidic water, raising its pH to a more alkaline level. This process can help to precipitate dissolved heavy metals, making them easier to remove. Additionally, mészoldásnak can be used for softening hard water by precipitating calcium and magnesium carbonates. In industrial processes, it serves as a flocculant, helping to aggregate suspended solids for easier separation.

Beyond water treatment, mészoldásnak finds applications in agriculture as a soil amendment to reduce acidity and provide calcium. It is also used in the food industry for processes like nixtamalization, where corn is treated to improve its nutritional value and texture. In construction, it has historically been used as a binder in mortars and plasters, though its use has largely been superseded by cement. The preparation and handling of mészoldásnak require care due to its alkaline nature, which can be irritating to skin and eyes.
