Study The Synergy Between ATMP and HEDP Water Treatment Chemicals

The scale inhibitor is a chemical component that is routinely treated in circulating water chemistry and plays an important role in chemical water treatment agents. It belongs to fine chemicals.

So what kind of scale inhibitor is the chemical composition, how to play a role?

To understand the principle of action of scale inhibitors, to better understand the important role of scale inhibitors in the treatment of circulating water.

Scale inhibitors, also known as scale inhibitors, are salts that form a chemical that inhibits the entry of scales.

Such as calcium and magnesium into scales. Inorganic inhibitors such as sodium hexametaphosphate, sodium tripolyphosphate, etc.

Organic, polymer scale inhibitors, among which polymer scale inhibitors have the best effect, have great development prospects.

Amino trimethylene phosphonic acid (ATMP) is adsorbed on the surface of a metal salt by electrostatic force to form a crystal (nuclear) surface, suppressing crystal growth, and maintaining the formation of many crystals in a microcrystalline state.

Due to the inhibitor molecules on the surface of the crystal, even if the crystal grows, the crystal grows abnormally, which causes the crystal to deform. The adhesion of the deformed crystal to the metal surface is weakened so that it is not easy to deposit the metal surface.

ATMP disperses insoluble inorganic salts in water, interfering with the deposition of poorly soluble inorganic salts in metal equipment. It can well maintain the good heat transfer effect of metal equipment and ensure normal production.

The scale inhibitor mainly includes some natural dispersants, phosphonic acid, phosphonic acid, and phosphonic acid and polymer, and most of the scale inhibitors currently used are high molecular polymers.

IRO studied the corrosion and scale inhibition properties of ATMP and HEDP composites.

The results show that when the ATMP: HEDP is 3:2, the corrosion rate can reach 95.61%. When the Ca2+ concentration is 250 mg/L, the corrosion rate can reach 92.03%.

When the ATMP: HEDP is 2:3, the scale inhibition rate can reach 93%. When the concentration of Ca2+ is 50~150 mg / L, the inhibition rate is over 90%.

The electrode curve shows that the ATMP and HEDP compounds are mixed inhibitors. The suppression effect is better, the corrosion product film is smoother and the structure is more compact.

And the metal is protected from the metal in order to better contact the corrosive medium.

Organic phosphonic acid water treatment agents are widely used in petroleum, chemical, recycling, metallurgical and pharmaceutical fields.

Current water treatment agents are less commonly used at one time but have a better synergistic effect when used with other agents.
