People often use heras as a fence in their construction area. Strong, sturdy, and many varieties. Those are some of the things that add value to this fence. Unfortunately, the heras fence can also be rotted by rust, making it look ugly. Why does it rust? How to fix it Before the fence rusts, it is usually marked with peeling fencing paint. Rust comes from metal, water, and air. Even though the three substances meet almost every time. That means any object made of metal almost entirely will rust one day. Additionally, if you don’t want to bother yourself in buying and maintaining temporary heras fences, we suggest you call the Heras fencing hire service in your city hirein.
Is it only metal that can be corroded? Not. All metals are prone to corrosion. However, there are some metals whose rust is non-destructive. The main problem of metal and steel is corrosion because corrosion can cause a decrease in quality.
Rust is the result of corrosion which has undergone oxidation on a metal or metal. Corrosion in the everyday language of rusting is metal damage due to a redox reaction between a metal and various substances in the environment which results in unwanted compounds due to electrochemical influences which are in direct contact with the environment in the form of water, air, gas, and others.
As we most commonly encounter in metal corrosion. This event undergoes a chemical reaction process that involves the presence of electricity. Part of metal (Fe) acts as a negative pole (anode), and part of air or oxygen (O2) acts as a positive pole (cathode). Electrons flow from the anode to the cathode so that it is oxidized while oxygen or air is reduced.
The rate of corrosion is very dependent on many factors, such as the presence or absence of an oxide layer, because the oxide layer can block the potential difference to the other electrodes.
Water is an important factor for the process of air corrosion which contains a lot of water vapor and will accelerate the corrosion process. Air that contains lots of oxygen gas will also cause corrosion.
