HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better. HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better.

HEDP is an organophosphoric acid corrosion inhibitor It can chelate with Fe Cu and Zn ions to form stable chelating compounds It can dissolve the oxidized materials on these metals surfaces HEDP shows excellent scale and corrosion inhibition effects under temperatures of 250C HEDP has good chemical stability under high pH values is hard to hydrolyze and is hard to decompose under ordinary light and heat conditions Its acidalkali and chlo rine oxidation tolerance are better than that of other organophosphoric acids salt HEDP can react with metal ions in the water system to form a hexaelement chelating complex with calcium ions in particular Therefore HEDP has good antiscale and visible threshold effects When built together with other water treatment chemicals it shows good synergistic effects Application HEDP is used as scale and corrosion inhibition in circulating cool water system oil field and lowpressure 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 dyefixing agent In noncyanide electroplating HEDP is used as chelating agent The dosage of 110mgL is preferred as scale inhibitor 1050mgL as corrosion inhibitor and 10002000mgL as detergent Usually HEDP is used together with polycarboxylic acid

Product Name: powder HEDP 90% Other Names: 1-Hydroxyethylidene-1,1-diphosphonic acid 1.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.. 2.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; 3.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. 4.Usually, HEDP is used together with polycarboxylic acid.

EDTMPA is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor. Its corrosion inhibition is 35 times better than that of inorganic polyphosphate. It is miscible with water, innocuous and none pollution to environment, has good chemical stability and temperature tolerance. It shows excellent scale inhibition ability under temperature 200C. It can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium.

PBTCA is widely used in the formulation of efficient scale and corrosion inhibitors and is one of the best performing products. It is also an excellent stabilizer for zinc salts. Widely used as a corrosion and scale inhibitor in circulating cooling water systems and oilfield water injection systems, it is particularly suitable for use in combination with zinc salts and copolymers. It can be used in high temperature, high hardness, high alkalinity, and situations that require high concentration ratios. PBTCA can be used as a chelating agent and metal cleaning agent in the washing industry. PBTCA is generally used in combination with other water treatment agents such as zinc salts, copolymers, organic phosphines, and azoles; If used alone, the dosage is 5-15mg/L.

BTA Na can be absorbed on metal surface and form a thin film to protect copper and other metals. BTA Na can be used together with many scale inhibitors and fungi disinfectants in circulating cool water system, and it has good corrosion inhibition effect in circulating cool water system. The dosage of 2-4mg/l is preferred. BTAâ?¢Na can also be used as anti-discolor agent, coating additive and luboil additive. Widely used in dimer acid, alkyd resin, synthetic fiber nylon 8 and 9, plastic plasticizer, printing ink, pesticide emulsifier, textile printing and dyeing auxiliaries, industrial solvents, detergents, metallic minerals flotation agent, remover, can also be used to make emulsified oil, metal processing oil, rust-proof oil, paint, oil is copy paper, pen, touch typing paper, detergent, laundry soap, softening agent, daily chemical and other industries.

Sodium sesquicarbonate is used in a variety of applications like to prepare detergents and soap, as an alkaline agent for cleaning, water softening, and leather tanning, as a pH regulator, raising agent, and anticaking agent in foods, and as a corrosion inhibitor for water purification. It is also used as a buffer in cosmetics. It's utilized in the archaeological: conservation of objects made of copper and copper alloys that have been corroded by salt water. It is also used as a precipitating water softener; it can combine with hard water minerals to form an insoluble precipitate, removing these hardness minerals from the water.
