Rozsdagátlók

Rozsdagátlók, also known as rust inhibitors or corrosion inhibitors, are chemical substances that, when added to an environment or applied to a surface, decrease the rate at which corrosion occurs. Corrosion is a natural process that converts a refined metal into a more chemically stable form, such as its oxide, hydroxide, or sulfide. This process is often electrochemical in nature.

These inhibitors work through various mechanisms. Some form a protective film on the metal surface, acting as a barrier between the metal and the corrosive environment. This film can be adsorbed onto the metal surface or precipitate from the solution. Other inhibitors might alter the electrochemical potential of the metal, making it less prone to oxidation. Certain types of inhibitors can also neutralize corrosive agents in the environment, such as acids or dissolved oxygen.

Rozsdagátlók are used in a wide range of applications. They are commonly added to cooling systems, boilers, and pipelines to prevent corrosion of metal components. In the automotive industry, they are a key ingredient in antifreeze and coolants. They are also used in metalworking fluids, lubricants, and coatings to protect manufactured parts during storage and use. The effectiveness of a particular rust inhibitor depends on the specific metal being protected, the nature of the corrosive environment, and the operating conditions. The selection of an appropriate rozsdagátló is crucial for effective corrosion prevention and extending the lifespan of metal structures and components.
