How to Choose a Sacrificial node
You have to understand that corrosion does not sit well with a boat or a ship. If you work in a ship, you can attest that fighting against corrosion is not a simple thing. When you look at most parts of a ship or boat, you will realize that a large percentage of it is made from iron. However, it is worth noting that ion is highly corrosive especially after coming into contact with water and air. Now that a ship or boat s always in water, it means that it is most likely to corrode; the outer part of it is always in water and that is why it ends up corroding. If you want to make sure that the outer part of a hip does not corrode, make sure that you use a sacrificial anode. If you do not know much about sacrificial anodes, make sure that you read this article and understand much.
You should not be afraid to use sacrificial anodes on your ship because they work without the need for any external power source. It is not any hard to insect anode material. A long as you make use of welds, brackets, or bolts, you are going to realize that installing sacrificial anodes is an easy thing. The fact that they reduce corrosion means that they will increase the durability of the ship.
Some of the common materials for sacrificial anodes include zinc, magnesium, and aluminum. Zinc was the commonly used material for sacrificial anode when in salty water. However, it is very heavy and toxic to the environment and that is why they have shifted. If you are looking for a lightweight material to use a sacrificial anode n salty or brackish water, then you should go for aluminum. Magnesium will prove to be beneficial in freshwater but will not help you if the water s salty. For brackish water, ensure that you use aluminum for a sacrificial anode.
Now that aluminum anodes are light, in addition to other benefits, they are taking the place of zinc. The fact that aluminum anodes use a much less toxic activator explains why they are always friendly to the environment. Use aluminum anodes for brackish and salty water because it will be able to prevent corrosion. If anyone does not want to keep replacing the anodes all the time; it would be good to use aluminum anodes because they last long. The most interesting thing about aluminum anodes is that they are suitable for both commercial and recreational applications; this means that anyone with a ship for recreational purposes can use such and prevent corrosion on the boat.
