Study on the Cleaning and Descaling Anticorrosion Technology of Water Cooling Engine without Disassembling

Through analyzing the causes and damage of the fouling in water channel of water cooling engine, this paper develops a new kind of compound cleaning and descaling agent and conducting polyaniline corrosion agent of the water tank. This new cleaning agent is stable and harmless, and can be added to the cooling system directly without the special equipment. With the circulation of the coolant, the agent can remove the scale, and then the removed scale flows out of the auto with the coolant. Except for this new cleaning agent, the antiseptic, whose major agent is the conducting polyaniline, can decrease and even stop the corrosion of the water tank and cooling system’s parts, and at the same time, the formation of the scale can also be restrained notably. When the agent is in use, it can be added(press 1% ratio to join) wholly into the water port, or complemented at any time, so that the quick cleaning and the anticorrosion are realized without disassembling and corroding the engine. By using these agents the cleaning efficiency of the engine cooling system is improved, the favorable engine’s technology situation is kept, and the engine’s life-span is also increased efficiently.

Study of corrosion resistance improvement by metallic coating for overhead transmission line conductor

AbstractApplying anticorrosion grease and aluminum‐clad steel (AC) wires to ACSR have been adopted as general methods to protect overhead transmission line conductors and/or wires from corrosion. However, in some cases those means have been found to be ineffective on some transmission lines passing through acid atmosphere in the vicinity of a factory exhausting acid smoke. The corrosion caused by acid atmosphere is characterized by a higher speed in its progress as is well known.As means against such acid corrosion, application of high‐purity aluminum, selective removal of intermetallic compound in aluminum, and plastic coating wires have been reported before, and each has both advantages and disadvantages. In a former report, we found that a new type of anticorrosion grease shows an excellent property against acid atmosphere as well as in a salty condition.Here we present a new type of anticorrosion technology of applying high‐corrosion‐resistance aluminum alloy or zinc coatings on each component wire of a conductor that we succeeded in developing through a serial study of anticorrosion methods on overhead transmission lines. © 2008 Wiley Periodicals, Inc.

State and prospects of inhibitor protection of the metal resources of the Ukraine

At present, the overall losses caused by corrosion in the Ukraine are very high and increase constantly owing to an increase in the aggressiveness of the environment and a lack of corrosion-resistant materials and anticorrosion technologies. The corrosion-mechanical fracture of metals (corrosion fatigue or corrosion cracking) proves to be the most dangerous type of corrosion since it occurs without visible changes in the appearance of structures. This is true, first of all, for pipelines, chemical and power equipment, municipal utility services, etc.
