YB-503 Scale and Corrosion Inhibitor for Boiler is built with organophosphine and polycarboxylic acid. It has advantages of high efficiency of scale & corrosion inhibition and good temperature tolerance. It can be used in water treatment of low pressure boiler. Boilers include radiator, steam, locomotive, etc.
YB-503B Scale and Corrosion Inhibitor for Boiler is composed of chelating, cleaning and dispersing agents. It has effects of both cleaning and corrosion inhibition, and has the advantages of fast cleaning, good effect, a low corrosion rate. It has little damage to boiler body and is not affected by Fe and Cu ions in water system. It is suitable for medium/low pressure boiler.
(Ethylenedinitrilo)-tetramethylenephosphonic acid has high capacity for chelating metal ions. The complex constant with Cu is the largest in all chelating agents including EDTA. It is a kind of high-pure grade reagent and innocuous, it can be used as detergent in semiconductor chip to prepare integrated circuit, as carrying agent for radioelement in medical industry, and as agent for inspection and therapy.
(1-Hydroxyethylidene)bisphosphonic acid, sodium salt is used in circulating cool water system, medium and low pressure boiler, oil field water pipelines as scale and corrosion inhibitor in fields such as power plant, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, this product is used as detergent for metal and nonmetal. In dyeing industry, this product is used as peroxide stabilizer and dye-fixing agent. In non-cyanide electroplating, this product is used as chelating agent.
Tetrasodium salt of amino trimethylene phosphonic acid can inhibit the scale formation, calcium carbonate in particular, in water system. It can be used in circulating cool system in power plant, oil refinery plant and oilfield refill water system. It has good synergistic effects with other additives, in neutral to acidic condition, no ammonia smell is let off.
Hexamethylenebis(nitrilodimethylene)tetraphosphonic acid can inhibit most scale formation such as calcium carbonate, calcium sulfate, barium sulfate and ferric oxide. As water treatment chemicals, it is used as scale inhibitors for calcium sulfate and barium sulfate, for calcium sulfate in particular. It has high scale inhibition rate and can last for long effective time. It can be used for crush treatment in oilfield and for water treatment in boiler.
EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor.Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It can be used as corrosion inhibitor in circulating cool water system and boiler water.
Bis(hexamethylene)triamine penta(methylenephosphonic acid) is a high-efficient chelating scale inhibitor, it has good effect to carbonate and sulfate scale.It has good water soluble properties and heat tolerance.It has high calcium ion tolerance in a wide pH ranges and temperature.
Ethylenediamine tetra(methylenephosphonic acid) pentasodium salt is a neutral solid product. It is nitrogenous organic polyphosphonic acid, which is a part of cathodic corrosion inhibitor. It can be used as scale and corrosion inhibitor for circulating water and boiler water system, chelating agent in non-cyanide electroplating, water-softening agent in dyeing industry, etc.
