Activated Carbon

Properties:
HEDP is an organic phosphonic acid corrosion inhibitor, can dissociate into five positive and negative ions in the water, can chelate Divalent metal ions in the water, and iron, copper, aluminum, zinc and other metal ions forming a stable complex, has a good scale effect. This product is resistant to high temperature and oxidation resistance, remained stable at high PH. Corrosion inhibitors for HEDP and other compound used, has a good synergy. And on device has good corrosion inhibition of carbon steel, low toxicity, it will not cause environmental pollution.

Usage:
HEDP is widely used in electric power, chemical industry, metallurgy, fertilizers, low pressure boilers, industrial circulating water system and oilfield water injection and oil pipeline and salt and moly bdate and zinc as well as copolymer compound used, main role inhibition and inhibition. In addition, they can also be used as a cyanide-free electroplating complexing agents, detergent for surface treatment of metals and non-metals, hydrogen peroxide stabilizer, metal ion masking agents, and so on.


Using method:
HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid.

Package and Storage:
