chloro-trimethylene phosphonic acid is used in the recirculating cooling water system of thermal power plant, refinery and oil field reinjection water system. Can play a role in reducing metal equipment or pipeline corrosion and scaling. Amino trimethylene phosphonic acid is used as a metal ion chelating agent in textile printing and dyeing and other industries, and can also be used as a metal surface treatment agent.
It can be used as a scale inhibitor for open circulating cooling water system and boiler water. It can also be used as a scale inhibitor for oil field sewage reinjection system with high hardness and poor water quality and for power plant condenser cooling water system. With good chelation, low limit inhibition, etc., can prevent the formation of scale in water scale salt. Used for circulating cold water, oil field water injection, water treatment of water-containing pipeline. It can form multiple ring chelates with metal ions such as calcium and magnesium, and disperse in water in loose form, but its inhibitory effect on calcium phosphate is not as good as that of ethylenediamine tetramethylene phosphonic acid. It can also be used as a metal cleaning agent to remove grease on metal surfaces, and also used as an additive for detergents, a metal ion masking agent, a cyanide-free electroplating additive, an extractant for precious metals, and the like.
benzotriazole on copper, aluminum, cast iron, nickel, zinc and other metal materials have anti-corrosion effect. Can be combined with a variety of corrosion inhibitors, such as with chromate, polymeric phosphate, molybdate, silicate, nitrite, ATMP, HEDP, EDTMP, etc., can improve the corrosion inhibition effect. The corrosion inhibition effect is very good in the closed circulating cooling water system. Can be used with a variety of scale inhibitors, bactericidal algaecide, benzotriazole on the corrosion inhibition of polyphosphate does not interfere, the oxidation resistance is very strong. However, when it exists together with free chlorine, the corrosion inhibition of copper is lost, and after the disappearance of chlorine, the corrosion inhibition is restored. Its concentration is generally 1-2mg/L, and the corrosion inhibition is very good in the range of pH 5.5~10, but the corrosion inhibition is reduced in the medium with low pH value.
Used in anti-rust oil (Grease) products, mostly used in copper and copper alloy vapor phase corrosion inhibitor circulating water treatment agent, automobile antifreeze, photographic antifogging agent, polymer stabilizer, plant growth regulator, lubricating oil additive, ultraviolet absorber, etc. This product can also be used in combination with a variety of scale inhibitors and biocide.
this product is used as a corrosion inhibitor for copper and copper alloy, similar to benzotriazole (BTA), and the actual commodity also includes 4-methylbenzotriazole ([29878-31-7]) or a mixture of the two, referred to as TTA. Benzotriazole corrosion inhibitors can form insoluble stable complexes with cuprous ions, adsorbed on the metal surface, forming a stable and inert protective film with a thickness of only 5 × 10-7cm, but It is very stable in various media, so that the copper alloy is protected.
JIANGYIN TRUST INTERNATIONAL INC was established in 1996, dedicated to the production and export of water treatment chemicals, intermediates, and other chemicals.
