Paper Industry
-
Bleaching Agent
Bleaching Agent: Quicklime is utilized to bleach cellulose pulp, enhancing the brightness and whiteness of paper.
-
Caustic Soda Regeneration
Caustic Soda Regeneration: It regenerates caustic soda, a key chemical used in the pulp-making process, contributing to the closed-loop system in modern pulp mills.
-
Water Treatment
Water Treatment: Quicklime is employed to treat residual water from the pulp production process, ensuring environmental compliance.
-
Dissolving Wood Elements
Dissolving Wood Elements: It helps dissolve non-cellulose components of wood, such as lignin, improving the quality of the pulp.
-
Producing Precipitated Calcium Carbonate (PCC)
Producing Precipitated Calcium Carbonate (PCC): Quicklime is critical in producing PCC, a high-purity mineral that serves as a filler in paper. PCC increases volume, improves porosity, brightness, and opacity.
-
Industrial Waste Treatment
Industrial Waste Treatment: Quicklime treats industrial sludge, wastewater, and flue gas, reducing pollution from paper mills.
-
Reducing Pulp Quantities
Reducing Pulp Quantities: By improving paper quality, quicklime can reduce the amount of pulp required, making paper production more efficient.
-
Reducing Tree Usage
Reducing Tree Usage: Quicklime contributes to sustainability by decreasing the need for trees in paper production.
