How to use HEDP-Na2?

HEDP-Na2, as a chaical that plays an important role in many fields, is generally used as a scale inhibitor at a concentration in the range of 2 to 20 mg/L. For example, in some industrial cooling circulating water systas, when the content of calcium and magnesium ions in the water is relatively low and the tendency of scale formation is not very significant, the concentration of HEDP Na2 can effectively inhibit the formation of scale by controlling it at about 2-10mg/L.

Application analysis of scale inhibitor HPAA

Scale inhibitor HPAA (2-hydroxyphosphoric acid acrylic acid) is a widely used scale inhibitor in water treatment. It has the following main application analyses:

  1. Scale inhibition against calcium and magnesium scale: HPAA can prevent the generation and deposition of calcium and magnesium scale by forming stable complexes with calcium and magnesium ions. This scale inhibition effect is very important in the water treatment process, which can effectively reduce the clogging problem of calcium and magnesium scales in systems such as pipelines, equipment and heat exchangers.
  2. Inhibition of iron rust and copper scale: HPAA also has the inhibition of iron rust and copper scale. It can complex with iron ions and copper ions to form stable complexes, thus reducing the generation and deposition of iron rust and copper scale and keeping the system clean and normal operation.
  3. Lifting effect on scale: In the system where scale has been formed, HPAA can lift the formed scale and prevent its further deposition and growth through chemical reaction with calcium and magnesium ions in the scale. This is very beneficial for cleaning and restoring equipment and pipelines already affected by scale.
  4. Synergistic effect with other scale inhibitors: HPAA can be used in conjunction with other scale inhibitors such as HEDP (Hydroxyethyl Phosphate) to form a synergistic effect and enhance the scale inhibition effect. This synergistic effect is widely used in the water treatment industry to improve the efficiency and performance of scale inhibitors.

It should be noted that the specific application analysis also needs to consider the specific water treatment conditions and system requirements, so in the actual application, it is recommended to adjust and optimise according to the specific situation. At the same time, when using HPAA or other chemicals, please be sure to follow the relevant safety operating procedures and regulatory requirements.

In which industry is HPAA more widely used and what do I need to be aware of?

The Chinese name of HPAA, 2-hydroxyphosphonoacetic acid, is more widely used in the water treatment industry. It is an excellent corrosion inhibitor, which can be used to prevent metal corrosion and sediment formation in water. In addition, HPAA can be used in water treatment processes in petrochemical, textile, paper, leather and other industries.
It should be noted that HPAA is an organophosphate compound, which is toxic and irritating. In the process of use, care should be taken to avoid direct contact with skin and eyes, such as inadvertent contact, should be immediately flushed with large amounts of water, and promptly seek medical attention. In addition, HPAA should be stored in a cool, dry, well-ventilated place, avoiding contact with oxidising agents, acids and other substances to avoid dangerous reactions.

Ingredients and uses of HPAA

Main Ingredients:

The chemical name of HPAA is ethyl 2-hydroxyphosphate and its chemical formula is C2H7O6P.

Main Uses:

Corrosion inhibitor: HPAA can be used as a corrosion inhibitor for steel, copper, zinc and other metals. It can form a protective phosphate film with the metal surface and reduce the contact between the metal and the oxygen and moisture in the environment, thus playing the role of corrosion inhibition.

What is the difference between DTPMPA and HEDP?

DTPMPA (diethylenetriaminepenta-methylphosphonic acid) and HEDP (hydroxyethylidene diphosphonic acid) differ in several aspects, and the following is a detailed analysis of the differences:

I. Basic properties

Second, the chemical structure and composition

  • DTPMPA: is a compound containing multiple amino and phosphonic acid groups, with a complex molecular structure, which makes it able to form a variety of stable complexes in water, thus providing excellent scale and corrosion inhibition.
  • HEDP: It is an organophosphonic acid compound with two phosphonic acid groups in its molecule, which can form stable complexes with metal ions (such as calcium ions) in water, thus playing the role of scale and corrosion inhibition.

Third, performance characteristics

  1. Scale inhibition effect:
  • DTPMPA has excellent performance in high temperature and alkaline environment, and its scale inhibition effect is especially significant for insoluble salts such as calcium carbonate.
  • HEDP also has good scale inhibition effect, but compared to DTPMPA in some specific conditions of the scale inhibition effect may be more excellent.
