Sodium Hydrosulfide for Pulping and Paper Processing
Detailed Explanation:
In paper production, lignin must be removed from raw materials (such as wood) to isolate fibers for papermaking. Sodium hydrosulfide reacts with lignin, promoting its dissolution and enabling easier fiber release. This results in improved fiber structure, increased paper strength, and higher brightness. Additionally, by reducing the need for other chemicals, NaHS helps maintain paper quality while cutting production expenses.

Sodium hydrosulfide (NaHS) is used as a cooking additive in the papermaking industry to accelerate lignin dissolution, facilitating fiber separation.
This enhances paper strength and brightness while reducing the consumption of other chemicals during the pulping process, thereby lowering production costs.
