Key Functions of Sodium Formate in Global Leather Manufacturing Industry
Sodium formate has long served as an indispensable chemical auxiliary material within the leather processing chain, playing a core role in pH regulation during the leather production procedure.
In conventional leather production flows, raw hides undergo liming treatment with lime water and sodium sulfide, which leaves the processing liquid strongly alkaline with pH value commonly ranging between 9 and 10. Fluctuations in ambient temperature and residual grease content on raw hides will further push up the alkalinity of liming liquor and hinder subsequent processing steps. As a mild acidic agent, sodium formate solution is widely adopted to neutralize excess alkalinity and stabilize the pH index of liming pools.
Proven by industrial production data, the standard application dosage is prepared as 10% concentration aqueous solution, with 8–9 kilograms of sodium formate dosed into every 100 liters of processing water. Precise pH adjustment via sodium formate effectively optimizes liming outcomes, prevents finished hides from excessive hardening, and significantly improves the efficiency of subsequent dehairing processes. Proper addition of this chemical shortens dehairing working hours and cuts comprehensive production costs for leather manufacturers.
Industry analysts note that reliable pH stabilization performance makes sodium formate a preferred auxiliary chemical for tanneries worldwide, supporting standardized and high-efficiency leather manufacturing across the whole production cycle.
