Performance and purpose:
HEDP · Na4 is a sodium salt of HEDP and 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 and municipal clean water, and swimming pool sterilization.
HEDP · Na4 is a white powder solid, soluble in water, non hygroscopic, convenient for transportation, and suitable for use in harsh cold conditions. HEDP · Na4 belongs to the category of organic phosphonates as scale and corrosion inhibitors. It can form stable complexes with various metal ions such as iron, copper, and zinc, and can dissolve oxides on metal surfaces. It still has a good corrosion and scale inhibition effect at 250 ℃.
HEDP · Na4 is widely used for scale and corrosion inhibition in industrial circulating cooling water, low-pressure boilers, oilfield water injection, and oil pipelines in industries such as power, chemical, metallurgical, and fertilizer; HEDP · Na4 can be used as a cleaning agent for metals and non-metals in the textile industry, a peroxide stabilizer and fixing agent in the printing and dyeing industry, a cyanide free electroplating complexing agent, and a daily chemical additive.
Quality indicators:
Packaging and storage:
HEDP · Na4 liquid is packaged in plastic drums, with a weight of 30kg or 250kg per drum. HEDP · Na4 solid is packaged in plastic woven bags lined with polyethylene bags, with a net weight of 25kg per bag, which can also be determined according to user needs. Store in a cool indoor place for a storage period of twelve months.
Safety and Protection:
HEDP · Na4 is alkaline and should be avoided from contact with eyes and skin. Once it splashes onto the body, it should be immediately rinsed with plenty of water.
