Description
Technical Field
The invention relates to an oil and rust removing agent and a preparation method and application thereof, belonging to the technical field of chemical preparations.
Background
Rusting is a chemical reaction and occurs when iron is left for a long time. Iron is easily rusted and is also very much related to external conditions besides being active due to its chemical properties. Moisture is one of substances that make iron easily rusted. However, iron does not rust only with water, and only when oxygen in the air is dissolved in water, the oxygen reacts with iron in an environment with water to form iron oxide, which is rust. Iron rust is a brownish red substance which is not as hard as iron and is easy to fall off, and after a piece of iron is completely rusted, the volume can be expanded by 8 times. If the rust is not removed, the sponge-like rust is particularly prone to absorb moisture and the iron will rust faster. Iron may weigh more when rusted, about 3 to 5 times the original weight.
The traditional chemical rust removal usually uses strong acid, and the acid can react with iron rust and metal oxide to generate soluble salts, so that the purpose of rust removal is achieved, and the acid can react with base metal to release hydrogen while rust removal, and the hydrogen can generate pressure on the iron rust and indissolvable oxide skin, thereby being beneficial to the stripping of the iron rust and the reduction of high-valence iron, and accelerating the acid cleaning process, but the traditional acid liquid treatment method also has obvious defects: namely, the generation of a large amount of hydrogen in the treatment process can cause the hydrogen embrittlement phenomenon of steel, cause the reduction of the mechanical property of metal and influence the strength of the steel; meanwhile, acid mist is easily formed, which affects the health of operators and corrodes surrounding equipment and environment; the consumption of acid liquor is also large, and the treatment cost is increased; such acids can cause over-corrosion of the steel. In addition, the large amount of generated residues need to be discharged frequently, which not only seriously corrodes industrial pipelines, but also pollutes soil and environment. In addition, strong acids are not easily transported and present a certain risk.
In order to solve the problems, an oil and rust removing agent which does not use strong acid, has high efficiency, simple operation and convenient transportation is urgently needed.
