APPLICATION

Steel Industry

Steel plays one of the crucial roles in Automotive Industries, Constructions and country’s economy and security. In steel manufacture Quick Lime acts as a flux in purifying steel. Lime is also used in metallurgical plants and refractory’s thus making it integral to metal manufacturing.

Paper Industry

Lime is a primary raw material for paper and pulp industry. Both Quick Lime and Hydrated Lime are essentially required for the manufacturing of pulp and paper in order to enhance the quality of paper by maximizing its opacity.

Chemical Industry

Lime contributes to a great deal in the chemical industries. Sigma’s premium products pride and pearl have found application in manufacturing of fine chemicals.

Road Building

Lime is used in stabilizing the inplace- soils or aggregate used in road building. Hydrated Lime helps in forming an impermeable base thereby reducing the chances of seepage of rainwater.

Leather Industry

Since time immemorial lime has been used for dehairing and plumping hides preparatory to leather tanning. A cleaning agent in the leather manufacture process, lime is used to remove raw skin and thus obtain clean leather.

Agricultural Uses

Lime is popularly used to increase the soil pH level and increase the crop yield. It is also used to improve the physical structure of the soil by reducing surface crusting. It is also used for soil liming, compost, disposal of animal products, fertilizers etc.

Lubricant

Used during Plastic extrusion as a lubricant in petroleum refining and also lubricating grease manufacturing process.

Glass Industry

Limestone and lime are the fluxing materials for glass. There is no substitute for liming materials in glass when color is important.

Construction Industry

As a building material lime is one of the oldest- probably only antedated by stone and mud. Lime has long been used in the construction industry to make mortar and plaster, serving as a binder in these substances.

Water Treatment

Lime is extensively used to treat municipal waste waters and industrial liquid wastes. In wastewater treatment plants (both urban or industrial) Hydrated Lime and Quick Lime are widely used for correcting the pH balance of acidic water.

Pharmaceutical Industry
