Product Profile of Detergent Grade Zeolite [zeolite-a]
National aluminium company ltd. [nalco] is considered to be a turning point in the history of indian aluminium industry. In a major leap forward, nalco has not only addressed the need for self-sufficiency in aluminium, but also given the country a technological edge in producing this strategic metal to the best of world standards. Nalco was incorporated in 1981 in the public sector, to exploit a part of the large deposits of bauxite discovered in the east coast.
Synthetic detergent grade zeolites [sodium alumino silicates], which are similar to natural minerals, were found to be highly effective builders. Given their function, effectiveness and their safe ecological properties, synthetic zeolites have been accepted as environmentally compatible builders.
Advantages of zeolite-a
- Average particle size 4 micron and maximum size not exceeding 20 micron of zeolite-a has made it suitable to pass through the mesh size of clothes, preventing greying thereby.
- Due to cubical shape with rounded corners and edges, zeolite-a crystals do not remain on fabrics and are easily removed on rinsing.
- The unwanted water soluble dirt molecules are absorbed on zeolite particles.
- It coagulates the colloidal dirt and pigments causing easy removal.
- The presence of zeolite-a does not interfere with the bio-degradation of linear alkyl benzene sulfonates [labs].
- Zeolite-a particles tend to form aggregate with other sewage constituents and are largely eliminated in the pre-sedimentation of sewage treatment.
- Zeolite-a is formulated in detergents to the extent of 25-30%.
Nalco`s zeolite-a
Nalco`s detergent grade zeolite plant is based on indigenous technology developed by m/s csmcri, bhavnagar licensed through nrdc. Production of zeolite-a directly in the loop of nalco`s alumina refinery, based on sodium aluminate liquor as the main feed stock. Zeolite-a plant is located adjacent to refinery complex of nalco at damanjodi. Product quality: specification of nalcos zeolite-a [data sheet] is at par with international standards.
