Aminotrimethylphosphonic acid ATMP is used for circulating cooling water in thermal power plants, refineries, and oilfield water injection systems. It can reduce the corrosion and scaling of metal equipment or pipelines. ATMP is used as a metal ion chelating agent in industries such as textile printing and dyeing, and can also be used as a metal surface treatment agent. ATMP solid is a crystalline substance that is easily soluble in water, hygroscopic, easy to transport and use, especially suitable for cold winter areas. Due to its high purity, it can be used as a metal chelating agent and metal surface treatment agent in the textile printing and dyeing industry.

Hydroxyethylene diphosphate (HEDP) is an organic phosphate scale and corrosion inhibitor that can form stable complexes with various metal ions such as iron, copper, and zinc, and can dissolve oxides on metal surfaces. It has better resistance to acid, alkali, and chlorine oxidation compared to other organic phosphates (salts). HEDP can form a six ring chelate with metal ions, especially calcium ions, in water. Therefore, HEDP has a good scale inhibition effect and a significant solution limiting effect. When used in combination with other water treatment agents, it exhibits an ideal synergistic effect. HEDP solid belongs to high-purity products and is suitable for cold regions in winter; Specially suitable for cleaning agents and daily chemical additives in the electronics industry.

EDTMPS, a nitrogen-containing organic polyphosphonic acid, is a cathodic corrosion inhibitor with a corrosion inhibition rate 3-5 times higher than inorganic polyphosphates. It can be mixed with water, non-toxic and pollution-free, has good chemical stability and temperature resistance, and still has good scale inhibition effect at 200 ℃. EDTMPS can dissociate into 8 positive and negative ions in aqueous solution, thus chelating with multiple metal ions to form multiple monomer structured macromolecular network complexes that are loosely dispersed in water, disrupting the normal crystallization of calcium deposits. EDTMPS has a good scale inhibition effect on calcium sulfate and barium sulfate scale.

Diethylenetriamine pentamethylphosphonic acid DTPMPA is used as a scale and corrosion inhibitor in water treatment for circulating cooling water and boiler water, especially suitable for alkaline circulating cooling water as a pH free scale and corrosion inhibitor. It can also be used as a scale and corrosion inhibitor in oilfield water injection, cooling water, and boiler water with high barium carbonate content; When used alone in compound formulations, there is no need to add dispersants, and the amount of dirt deposition is still very small. DTPMPA can also be used as a peroxide stabilizer, chelating agent for textile printing and dyeing, dispersant for pigments, oxygen delignification stabilizer, trace element carrier in fertilizers, and concrete additive. In addition, it has also been widely used in papermaking, electroplating, metal pickling, and cosmetics. It can also serve as a stabilizer for oxidizing agents.
