ATMP, Organic Phosphonic Acid in Water Treatment Chemicals

There are many types of organic phosphonic acids, but in their molecular structure, they contain a phosphonic acid group directly attached to a carbon atom. And the molecule may also contain groups such as -OH, -CH₂ or -COOH.

The organic phosphonic acid can be classified into a diphosphonic acid tri-phosphonic acid tetra phosphonic acid penta phosphonic acid or the like according to the number of phosphonic acid groups contained in the molecule.

According to the type of molecular structure, the organic phosphoric acid can be further classified into a methylidene phosphonate type, a homocarbo diphosphonic acid type, a hydroxy acid phosphonic acid type, and other atomic phosphonic acid types.

Organic phosphoric acid is a new product developed in the late 1960s. However, it was widely used in circulating cooling water treatment in the 1970s. This is because it has the following advantages.

First, they all have a C-P bond in their molecular structure, and this bond is much stronger than the P-O-P bond in polyphosphate. Therefore, it has good chemical stability, is not easily hydrolyzed, and is resistant to high temperatures. In the use, it does not cause orthophosphoric acid to be overproduced due to hydrolysis.

Second, it has a critical effect like polyphosphate. It is only necessary to use a small amount of organic phosphonic acid to prevent the precipitation of a large amount of calcium carbonate.

In actual use, it has been found that the use of an organic phosphonic acid in combination with a polyphosphate is better than any single species.

In addition to polyphosphate, it also has a good synergistic effect with a variety of agents. Therefore, in practical use, people often choose the compound formula with the best synergy.

In addition to the above advantages, the organic phosphonic acid also has good corrosion inhibition properties at high doses and is a non-toxic or extremely low toxicity agent. Therefore, there is no need to worry about environmental pollution during use.

ATMP is a commonly used organic phosphonic acid agent in circulating cooling water. It is a corrosion inhibitor and scale inhibitor widely used in the boiler water equipment industry.

After compounding, it has good corrosion inhibition performance and the inhibition rate is more than 98%. Its scale inhibition performance is higher than 90% in hard water.

After mixing with ATMP acid, it can be used for scale inhibition and corrosion inhibition in hot water boilers. It has the advantages of low consumption, corrosion inhibition and good scale inhibition.

The chemical name of ATMP is amino trimethylene phosphonic acid. It has good chemical stability, is not easy to hydrolyze, and is resistant to high temperatures. When used in combination with zinc salts, copolymers, etc., it has good synergistic effects and solubility effects.

This product also has good corrosion inhibition performance at high dosage, and it is a non-toxic, pollution-free agent. This product has good dispersion and scale inhibition performance for calcium carbonate scale.

Water treatment chemicals are an important part of water treatment, and it is particularly important to strengthen the development of water treatment drug formulations with high efficiency and low toxicity green water treatment chemicals.

Purchasing water treatment chemicals cannot be blindly mapped to cheap. Water treatment chemicals are only a small fraction of expensive industrial equipment. So be sure to buy regular manufacturers of water treatment chemicals, professionals are added and processed.
