Industrial Applications
Industrial Boiler Water System Treatment
In high-pressure boiler feedwater treatment, STPP effectively controls scale formation and prevents heat transfer efficiency reduction.
Through chelation, it maintains long-term stable operation of boiler systems.
Metal Surface Phosphating Pre-treatment
In metal coating pre-treatment processes, this product optimizes phosphating bath stability and promotes dense phosphate film formation,
significantly enhancing subsequent coating adhesion and corrosion resistance.
Industrial Wastewater Softening
In high-hardness industrial wastewater pre-treatment, STPP efficiently chelates calcium and magnesium ions to reduce water hardness,
creating favorable conditions for subsequent membrane treatment or ion exchange processes.
