Tungsten Oxide

In order to protect the environment, human efforts to develop new, efficient, low toxicity, pollution-free corrosion inhibitors, sodium tungstate quickly favored by people. Sodium tungstate was first used as a corrosion inhibitor for organic antifreeze, and subsequently developed in other functional packages. Tungstic acid can be used in different corrosive media, such as fresh water cooling water, seawater cooling water, oil recovery in the oil field, molten salt, water-cooled internal combustion engine antifreeze, adsorption type refrigerant circulating fluid and coal slurry. You can also add anti-rust paint and mold resin material from the role of corrosion inhibition. Sodium tungstate alone has some inhibition, but the corrosion rate is not high, and the amount is large, the cost is difficult to control, therefore, sodium tungstate is mixed with other organic compounds in general industry, which can significantly improve the corrosion inhibition performance and reduce the cost of ...

In recent years, in order to save fresh water resources and reduce the cost, some of the coastal chemical, metallurgy, electric power and petrochemical enterprises began to use seawater as a type of industrial circulating cooling water. Although this practice has many advantages, in the sea cl -  content is high, easy to produce metal corrosion, metal corrosion is one of the most important destructive factors, which can cause corrosion and perforation of equipment and pipes, cause serious corrosion, and cause enormous economic losses and social harm. In order to reduce the probability of metal corrosion, it is a simple and effective anti-corrosion method to add inhibitors to circulating cooling water. Only common chromate, nitrite, phosphate and other corrosive agents are toxic preparations, excessive use is tantamount to quenching thirst with poison, research and development of low toxicity, non-toxic and effective corrosion inhibitors have a greater significance. ...
