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.

2-Butane-1,2,4-tricarboxylic acid PBTCA is widely used in the formulation of scale and corrosion inhibitors, and is one of the high-performance products. It is also an excellent stabilizer for zinc salts. Widely used as a corrosion and scale inhibitor in circulating cooling water systems and oilfield water injection systems, PBTCA is particularly suitable for compounding with zinc salts and copolymers. It can be used in high temperature, high hardness, high alkalinity, and situations that require high concentration ratios. PBTCA can be used as a chelating agent and metal cleaning agent in the washing industry.

Polyphenol phosphate ester PAPE is a new type of water treatment agent with good scale and corrosion inhibition performance. Due to the introduction of multiple polyoxyethylene groups into the molecule, not only does it improve corrosion inhibition performance, but it also enhances the ability to inhibit calcium scale and disperse sediment. It has an excellent inhibitory effect on the deposition of barium and strontium scales in water that cannot be controlled by existing scale inhibitors in China. It also has an excellent scale inhibition effect on the deposition of insoluble salts such as calcium carbonate and calcium sulfate in water. It has a cathodic protection effect on steel and its corrosion inhibition effect is better than similar products in China. Polyol phosphates are well mixed with water stabilizers such as polycarboxylates, organic phosphates, inorganic phosphates, and zinc salts. Polyol phosphate ester is used as a scale inhibitor for oilfield water injection collection (especially recommended as a substitute for Nalco Visco 953), and as a corrosion and scale inhibitor for industrial cooling water treatment.

2-hydroxyphosphonoacetic acid HPAA has good chemical stability, is not easily hydrolyzed, and is not easily damaged by acid or alkali. It is safe and reliable to use, non-toxic and pollution-free. HPAA can improve the solubility of zinc and has a strong corrosion inhibition effect. The corrosion inhibition performance of HPAA is 5-8 times higher than that of HEDP and EDTMP. The organic corrosion and scale inhibitor composed of HPAA and low molecular weight polymers has excellent performance.

BHMTPMPA, a chelating scale inhibitor, has excellent scale inhibition effects on carbonate and sulfate scales. Used as a corrosion and scale inhibitor for oilfield water treatment, as well as a scale and corrosion inhibitor for industrial circulating cooling water and boiler water.

Phosphonyl carboxylic acid copolymer POCA introduces phosphonic acid groups onto the original carboxylic acid group, which has good dispersibility for calcium carbonate and calcium phosphate scale in circulating cooling water, and has a good inhibitory effect on the deposition of barium sulfate, strontium sulfate, and silicon scale; The combination of POCA and other organic phosphonates and copolymers has a synergistic effect. POCA has the characteristics of wide applicability to water quality, good chemical stability, and strong resistance to chlorine oxidation. POCA is mainly used for scale inhibition and corrosion inhibition in industrial circulating cooling water systems and oilfield water injection systems.
