CALCIUM HYDROXIDE 25kg

Calcium hydroxide (Hydrated lime) is traditionally called slaked lime, is an inorganic compound with the chemical formula Ca(OH)2.

It is a colourless crystal or white powder and is obtained when calcium oxide (lime or quicklime) is mixed, or ‘slaked’ with water.

Calcium hydroxide is used in many applications, including food preparation.

One significant application of calcium hydroxide is as a flocculant, in water and sewage treatment.

It is also used in fresh water treatment for raising the pH of the water so pipes will not corrode where the base water is acidic; hydrated lime is self-regulating and does not raise the pH too much.

 

Hydrated lime has many other applications:

As an ingredient in whitewash, mortar, and plaster In road construction, to improve the quality of excessively plastic subgrade soils.

As a long-lasting fungicide In the petroleum refining industry for the manufacture of additives to oils.

In the chemical industry for manufacture of calcium stearate.

For preparation of dry mixes for painting and decorating.

In manufacturing mixes for pesticides, and as a natural insecticide.

Because of its low toxicity and the mildness of its basic properties, slaked lime is widely used in the food industry as a clarifier for juices, for treating process water for alcoholic beverages and soft drinks, for pickling, and for brine clarific
