HEDP Chemical: High-Performance Scale and Corrosion Inhibitor for Industrial Water Systems

 HEDP chemical (Hydroxy Ethylidene Diphosphonic Acid) is a classic organophosphonate water treatment agent, renowned for its excellent scale inhibition, corrosion resistance and chelating properties. As a multi-functional additive, it is widely used in various industrial water systems, solving the core problems of scaling and metal corrosion efficiently.

HEDP has strong chelating ability with calcium, magnesium, iron, copper and other metal ions, which can effectively inhibit the crystallization and deposition of calcium carbonate, calcium sulfate, barium sulfate and other scales. It can also distort the crystal structure of existing scales, making them loose and easy to peel off, thus keeping pipelines and equipment clean. At the same time, HEDP can form a dense protective film on the surface of carbon steel, copper, stainless steel and other metal materials, isolating corrosive media and significantly reducing corrosion rates.
With excellent thermal stability and hydrolysis resistance, HEDP can maintain stable performance under high temperature, high hardness and high alkalinity conditions, making it suitable for circulating cooling water, boiler water, reverse osmosis systems and oilfield injection water. It is compatible with most water treatment additives such as polycarboxylates, zinc salts and biocides, and can achieve synergistic effect through compound use.
Shandong Kairui Chemistry Co., Ltd supplies industrial-grade HEDP with high purity, stable composition and competitive price, supporting bulk orders and global fast delivery. Our products meet international industry standards and are deeply trusted by customers in petrochemical, power, metallurgy and other industries.

what does hedp mean

  HEDP , or 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid , is an important organophosphonic acid compound. The following is its brief introduction: Properties : HEDP is usually a colorless to light yellow transparent liquid, which can be miscible with water in any proportion, and raains stable under high pH value, not easy to be hydrolyzed, and not easy to be destroyed by acid and alkali.   Mechanism of action : It can form stable chelate with metal ions, and prevent metal ions from forming insoluble salt precipitation through chelation, so as to play the role of scale inhibition; at the same time, HEDP can form a layer of protective film on the metal surface to inhibit the corrosion of the metal to achieve corrosion inhibition effect. Application : HEDP is widely used in industrial field, it is an excellent water treatment agent, commonly used in boiler water treatment, circulating cooling water systa, etc. It can effectively prevent scale generation and me...

How to use Sticky Sludge Stripper

 A Sludge Stripper is a chemical specifically designed to remove slime, biofilm and algae from industrial circulating water systems. Below are some key points and recommendations when using a Sludge Stripper: 1. Dosing rate: - As a slime stripper: the recommended dosage is usually 100-200 milligrams per liter (mg/L) based on the amount of water retained in the system. - As an algaecide: the recommended dosage is 50-100 mg/L. 2. 2. Special case treatment: - If there are more algae in the system, in order to get faster killing and stripping effect, the dosage of KR-409 can be increased appropriately. 3. Fouling removal: - After the use of KR-409, if the circulating water appears to be fouled due to the stripping effect, these floating materials should be removed in time to prevent them from being redeposited in the system. 4. Avoid mixing: - Mud strippers should not be mixed with anionic surfactants such as polyacrylic acid (PAA) or hydroxypropylmethylacrylate (HPMA). - Similarly, sl...
