HEDP
1-Hydroxy Ethylidene-1,1-Diphonic Acid (HEDP)

1.organic phosphonic acid,scale&corrosion inhibitor

2.purity 60% and 90%
3.used in water treatment and auxiliary agent

Characteristics:

HEDP is an organic phosphonic acid corrosion inhibitor and scale, with iron, copper, zinc and other metal ions to form a stable complex, to dissolve the surface of metal oxide. In the next 250 °C still play a good role in corrosion and scale inhibitors in high pH stability is still under difficult to hydrolysis, light and heat conditions in general difficult to break down. Acid, oxidation-resistant than other organic acid (salt) good. With metal ions in the water, in particular the formation of six calcium chelate ring, and thus be better and have the effect of scale soluble obvious effects are limited, and other water treatment agent using the compound has shown the desired synergy .
HEDP solid belong to high-purity products, applies to the winter cold regions; particular, the electronics industry apply to the cleaner use of chemicals and additives day.

Applications:
HEDP is widely used in electric power, chemical industry, metallurgy, chemical fertilizer, such as industrial cooling water system and, low-pressure boilers, water and oil pipeline corrosion and scale inhibition; in the textile industry, can be used for metal and non-metallic cleaning agent Peroxide bleaching and dyeing industry, stabilizer and the fixing agent, cyanide-free electroplating industry agent. HEDP scale inhibitor for the general use of the concentration of 1 ~ 10mg / L, for the general use of the concentration of corrosion inhibitor 10-50mg / L; cleaning agent for general use of the concentration of 1000 ~ 2000mg / L; usually associated with acid-type scale with dispersant
Packaging and storage:HEDP barrels of liquid plastic packaging, or 30Kg barrel 250Kg; HEDP solid polyethylene bag lined with plastic packaging bags, bag net weight 25kg, may also need to identify the user. Stored in a cool indoor ventilation, moisture, the storage period of 10 months.
Security:HEDP for the acid, should be avoided with the eyes, skin contact, splashed on him once, immediately wash with plenty of water.
