Incorrect Method of Preventing Rusting
Rusting is the process of corrosion of iron or steel when it comes in contact with water and air. Rust is a reddish-brown flaky coating that weakens the metal and makes it brittle. Therefore, it is necessary to prevent rusting to increase the life of the metal. The incorrect method of preventing rusting is as follows:
Covering Iron Articles with Plastic
This method is not effective in preventing rusting because plastic covers trap moisture and air, which accelerates the rusting process. Therefore, it is not recommended to cover iron articles with plastic.
Correct Methods of Preventing Rusting
There are several effective methods of preventing rusting, which are as follows:
Painting Iron Articles
Painting iron articles with a coat of paint creates a barrier between the metal and the environment, preventing the metal from coming in contact with moisture and air. Therefore, it is an effective method of preventing rusting.
Oiling or Greasing Machine Parts
Oiling or greasing machine parts prevents rusting by creating a thin layer of oil or grease that prevents moisture and air from coming in contact with the metal. Therefore, it is an effective method of preventing rusting.
Using Galvanised Iron Pipes
Galvanised iron pipes are coated with a layer of zinc, which prevents rusting by acting as a barrier between the metal and the environment. Therefore, it is an effective method of preventing rusting.
Conclusion
In conclusion, covering iron articles with plastic is not an effective method of preventing rusting. Instead, painting iron articles, oiling or greasing machine parts, and using galvanised iron pipes are effective methods of preventing rusting.
