Compared to cycloalcanic acids, which one has a greater corrosive effect on steel: acetic acid, butyric acid, or cycloalcanic acids?

Metal corrosion occurs under certain environmental conditions; it is also necessary to consider the effect of the medium on metal corrosion. For example, in the oil refining process, at temperatures between 220 and 400 degrees Celsius, corrosion intensifies as the temperature rises. For other acetic and butyric acids, they are weaker than naphthenic acids in such an environment. However, if the operating conditions are changed, the corrosivity of the corrosive medium will change as well.

Just conduct a hanging slice test, isn’t that enough? For corrosion conditions in situations that are not well understood, it is best to conduct corrosion coupon tests using the media present under those specific conditions; this is a good and reliable method.

Our factory supplies titanium anodes and electrodes directly, available in three categories: ruthenium-iridium series, iridium-tantalum series, and platinum series. These are mainly used in sodium hypochlorite generators, chlorine dioxide generators, disinfection equipment, pool water disinfection, industrial circulating cooling water systems, vegetable washing machines, the electrolytic production of hydrogen and oxygen, as titanium anodes for chlorine and oxygen evolution, the electrolytic production of hydrogen and chlorine from seawater, copper plating on circuit boards, electrochemical processing of aluminum foil, copper foil production, treatment of ammonia-nitrogen wastewater, and the electrolytic processing of copper, zinc, nickel, and other metals. The company can test and compare qualities; the prices are lower than market rates, and the quality is guaranteed. Consultation phone: 17392671310
