Folding organic phosphine series scale inhibitors

ATMP has good chelation, low limit inhibition and lattice distortion. It can prevent scaling of salt, especially calcium carbonate. ATMP has stable chemical properties in water and is not easy to hydrolyze. When the concentration is high in water, the corrosion inhibition effect is better.

HEDP is an organic phosphonic acid scale and corrosion inhibitor, which can form stable complexes with iron, copper, zinc and other metal ions, and can dissolve the oxides on the metal surface. It can still play a good role in corrosion and scale inhibition at 250 ℃, it is still stable at high pH value, and is not easy to hydrolyze and decompose under general photothermal conditions. The resistance to acid, alkali and chlorine oxidation is better than other organic phosphonic acids (salts).

Edtmps is a kind of nitrogen-containing organic polyphosphate, which is a cathode corrosion inhibitor. Compared with inorganic polyphosphate, the inhibition rate of edtmps was increased by 3-5 times. It is miscible with water, non-toxic and pollution-free, with good chemical stability and temperature resistance. It still has good scale inhibition effect at 100 ℃. Edtmps can be decomposed into eight positive and negative ions in aqueous solution, chelating with various metal ions to form a macromolecular complex network with monomer structure, which is loose and dispersed in water and destroys the normal crystallization of calcium scale. It has good scale inhibition effect on calcium sulfate and barium sulfate.

Edtmpa has a strong ability to chelate metal ions, and its complexation constant with copper ion is larger than that of all chelating agents including EDTA. Edtmpa is a highly pure and nontoxic reagent. It can be used as a cleaning agent for semiconductor chips in electronic industry and used for manufacturing integrated circuits; in the pharmaceutical industry, as a carrier of radioactive elements, it is used for the examination and treatment of diseases; the chelating capacity of edtmpa is much higher than that of EDTA and DTPA, and almost all materials can be replaced by edtmpa, where EDTA is used as chelating agent.

It is a neutral sodium salt of ATMP, which can prevent scaling salt from forming scale, especially calcium carbonate scale. ATMP？ Na4 is suitable for circulating cooling water system of thermal power plant, oil refinery and oilfield reinjection water system. ATMP？ Na4 has good compatibility with other additives. ATMP？ Na4 is particularly suitable for neutral to acidic formulations without ammonia.

ATMP？ KX is a part of ATMP potassium solution. Compared with the same amount of sodium salt, ATMP? KX has high solubility and can prevent scaling of scaling salts, especially calcium carbonate. ATMP？ KX is especially suitable for oilfield reinjection system.

Haidep? Na4 is widely used in power, chemical, metallurgy, chemical fertilizer and other industrial circulating cooling water, low-pressure boiler, oilfield water injection and oil pipeline scale and corrosion inhibition.

Folding polycarboxylic acid scale inhibitor and dispersant

PAAS is non-toxic, soluble in water, and can be operated in alkaline and medium concentration conditions without scaling. PAAS can disperse calcium carbonate, calcium sulfate and other salt microcrystals or sediments in water without precipitation to achieve the purpose of scale inhibition.

AA / AMPS is a copolymer of acrylic acid and 2-acrylamide-2-methylpropanesulfonic acid (AMPS). Because the molecular structure contains carboxyl group and strong polar sulfonic acid group with good scale inhibition and dispersion performance, the calcium resistance can be improved. The scale inhibition effect of calcium phosphate, calcium carbonate and zinc scale in water is obvious, and the dispersion performance is excellent. When it is mixed with organic phosphine, the synergistic effect is obvious. It is especially suitable for water with high pH, high alkalinity and high hardness. It is one of the most ideal scale inhibitors and dispersants to achieve high concentration and multiple operations.

PESA is a kind of "green" multi-element scale and corrosion inhibitor without phosphorus and nitrogen. PESA has good scale inhibition and dispersion performance for calcium carbonate, calcium sulfate, barium sulfate, calcium fluoride and silicon scale in water, and its scale inhibition effect is better than that of organic phosphorus scale inhibitor. The combination of PESA and phosphonate has a good synergistic effect. At the same time, PESA has a certain corrosion inhibition effect and is a multi-component scale inhibitor.

PASP is a water-soluble polymer and a new green water treatment agent. It has the characteristics of no phosphorus, no poison, no pollution and so on
