CHEMICAL HYDRATED LIME POWDER 50 T

0157202 – CHEMICAL HYDRATED LIME POWDER 50 T (Eskom Spec)

Chemical hydrated lime, also known as calcium hydroxide, is a highly reactive and versatile inorganic compound widely used in various industrial and construction applications. It is produced by the hydration of quicklime (calcium oxide) with water, resulting in the formation of a white powder with a strong alkaline pH. Chemical hydrated lime is characterized by its high water solubility, which allows it to release hydroxyl ions into solution, making it an effective neutralizing agent. It is commonly employed in water treatment processes for pH adjustment, wastewater neutralization, and sludge thickening. In the construction industry, chemical hydrated lime serves as a binder in mortars, plasters, and concretes, enhancing their strength and durability. Additionally, it is used as a soil stabilizer in road construction and as a reagent in chemical reactions, such as in the production of paper and glass.

Chemical Hydrated limeChemical Hydrated lime (calcium hydroxide) is a dry, colorless crystalline powder manufactured by treating calcium oxide (quicklime) with water, in a process called “slaking.” Also known as slack lime, builders lime or pickling lime, hydrated lime is used in the production of mortars, plasters, cements, paints, hard rubber products, petrochemicals, and in the tanning of leather.

A more recent development for hydrated lime use is in environmental applications. Here, hydrated lime, a mild alkali, is used for the removal of acid gases in coal-fired energy plants, cement mills, glassmakers and incinerators.

Frequently Asked Questions

Is powdered lime dangerous?

Skin Hazards—Lime can cause irritation and burns to unprotected skin, especially in the presence of moisture. Prolonged contact with unprotected skin should be avoided. ... Inhalation Hazards—Lime dust is irritating if inhaled.

Is hydrated lime dangerous to humans?

Hydrated lime is strongly alkaline and can cause severe injury. Contact with eyes or skin can cause irritation and possible irreversible tissue damage, corrosion damage, chemical burning and corneal damage.

What happens when you add water to hydrated lime?

Lime reacts readily with water to produce slaked lime, which is the chemical compound calcium hydroxide. A considerable amount of heat energy is released during this reaction. When carbon dioxide gas is passed through or over limewater, it turns milky due to the formation of calcium carbonate.

What is the difference between hydrated lime and lime?

The main differences between hydrated lime and quicklime are their reactivity & their chemical composition. ... In its hydrated state, calcium is called calcium hydroxide, and in its pure state it is called calcium oxide, or quicklime. Calcium oxide has a heavy density (65lb/ft³) and is more reactive than hydrated lime.2

What is powdered lime good for?

Garden lime is a rock powder used to raise the pH level of soils high in acidity. An application of lime sweetens a soil -- that is, it can make a sour soil more alkaline.

What are the dangers of lime?

Inhaling lime dust may lead to irritation of breathing passages, coughing and sneezing. If ingested, lime can cause pain, vomiting, bleeding, diarrhea, a drop in blood pressure, collapse, and in prolonged cases, it can cause a perforation of the esophagus or stomach lining.

What can I use hydrated lime for?

Hydrated lime (calcium hydroxide) is a dry, colorless crystalline powder manufactured by treating calcium oxide (quicklime) with water, in a process called slaking. Also known as slack lime, builders lime or pickling lime, hydrated lime is used in the production of mortars, plasters, cements, paints, hard rubber

Can you mix hydrated lime with water?

Hydrated lime and quicklime are both calcium compounds. ... Calcium hydroxide, or hydrated lime, is already neutralized, so it will not undergo oxidation and can be mixed with water in our system, for water ph control, lime slurry addition, lime slurry mixes, soil rehabilitation and more.

How long does hydrated lime last?

Most bagged, hydrated lime has a shelf life of 12 months once kept dry and sealed. Once opened bags should be used straight away or resealed so as to be airtight. Some premixed lime mortars with additives may have a shorter shelf life. Lime putty will last indefinitely once kept underwater and airtight.

Will lime kill dogs?

Although ingesting a little lime powder won't hurt your dog, watering it in would be safer. The pelletized products might be an even better bet: not dust, no tracking in the house. Thank you both very much! I think the pelletized lime is what I got.

What happens if a dog licks a lime?

There is a thing called Lime poisoning , but if your dog only licked a lime, than he would be completely fine. ... The lime is contains essential oils limonene and linalool and if your dog eats a lot of lemons or limes, than he will have gastrointestinal upset. Most likely he will suffer from diarrhea and vomiting.

Does lime cause cancer?

Long-term exposure by inhalation may cause permanent damage. This product contains crystalline silica, which has been classified by IARC as (Group I) carcinogenic to humans when inhaled.

Is hydrated lime explosive?

However, hydrate reacts vigorously with acids, and may release heat sufficient to ignite combustible materials in specific instances. Hydrate is not considered to be an explosion hazard, although reaction with acids or other incompatible materials may rupture containers.

Is Lime a coagulant or flocculant?

The aluminum coagulants include aluminum sulfate, aluminum chloride and sodium aluminate. The iron coagulants include ferric sulfate, ferrous sulfate, ferric chloride and ferric chloride sulfate. Other chemicals used as coagulants include hydrated lime and magnesium carbonate.

What does hydrated lime do to concrete?

Hydrated lime can be added to concrete mix used to make block and other concrete products in order to produce a denser, more water-resistant product.

What is the pH of hydrated lime?

Hydrated lime, though only slightly soluble in water, forms suspensions easily; the resulting solution and suspension is strongly alkaline, possessing a pH of 12.4.

Why lime is added with alum in jar test?

The purpose of lime is to create a stable pH environment - the ideal pH for iron alum environment is in the range of 7.5 - 8.5. In this environment, the flocculation is in the most perfect state and the flocculation time is the fastest. Therefore, lime is a factor that is dependent on iron alum.

Is lime mortar more expensive than cement?

+ Lime mortar is generally more expensive than cement based mortar? Yes, it is more expensive due to production cost of lime vs cement, basically down to volume of production. As more lime is produced, cost will reduce.

Is lime slurry hazardous?

Hydrated lime slurry is not considered to be an explosion hazard, although reaction with incompatible materials may rupture containers. Hazardous Combustion Products: None.

What happens when aluminum sulfate and lime water are mixed?

Mixing aluminum sulfate and lime together in water leads to formation of colloidal aluminum hydroxide, and this can bring about precipitation and removal of waterborne organic material. This method for water clarification is widely used. Al-containing additives are also found in many foodstuffs.
