A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles. Limescale is either white or brown in colour due to the presence of iron compounds .
Descaling agents are commonly used to remove limescale. Prevention of fouling by scale build-up relies on the technologies of water softening or other water treatment. This column in the Bad Münstereifel church in Germany is made from the calcium carbonate deposits that built up in the Roman Eifel Aqueduct over several centuries of use.
Solutions usually also contain additives such as wetting agents and corrosion inhibitors. Pickling is sometimes called acid cleaning if descaling is not needed. [2] [3] Many hot working processes and other processes that occur at high temperatures leave a discoloring oxide layer or scale on the surface. In order to remove the scale the ...
How do you descale your coffee maker? ... “You can also use sodium bicarbonate and other commercially available descaling agents,” he says.
(Descaling is the process of removing mineral deposits from the surface of a product.) Kuiper also suggests cleaning the exterior of these products on a weekly basis, if not more often. “The ...
Sulfamic acid is used as an acidic cleaning agent and descaling agent sometimes pure or as a component of proprietary mixtures, typically for metals and ceramics. For cleaning purposes, there are different grades based on application such as GP Grade, SR Grade and TM Grade.
They are commonly used as descaling agents to remove limescale deposits. The maximum amount of CaCO 3 that can be "dissolved" by one liter of an acid solution can be calculated using the above equilibrium equations. In the case of a strong monoacid with decreasing acid concentration [A] = [A −], we obtain (with CaCO 3 molar mass = 100 g/mol):
In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is controlled by the food additive code E260 as an acidity regulator and as a condiment. In biochemistry, the acetyl group, derived from acetic acid, is fundamental to all forms of life.
