What is HEDP Na4?
HEDP Na4 is the sodium salt of HEDP and is an excellent inhibitor of calcium carbonate scale. HEDP Na4 is mainly used for metal corrosion inhibition in low-pressure boiler water treatment, circulating water treatment, industrial municipal cleaning water, and swimming pool sterilization. HEDP·Na4 is a white powder solid, soluble in water, non-moisture-absorbing, easy to transport, and suitable for use in severe cold conditions. HEDP·Na4 is an organic phosphonate scale and corrosion inhibitor, which can form stable complexes with iron, copper, zinc and other metal ions, and can dissolve oxides on the metal surface. It still plays a good role in corrosion and scale inhibition under the condition of 250 ℃. HEDP·Na4 is widely used in scale and corrosion inhibition of electric power, chemical industry, metallurgy, fertilizer and other industrial circulating cooling water, low-pressure boilers, oilfield water injection and oil pipelines. HEDP Na4 can be used as metal and non-metal cleaning agent in textile industry, peroxide stabilizer and color fixing agent in printing and dyeing industry, cyanide-free electroplating complexing agent, daily chemical additive.
