Let’s take the solution to the rust of a large industrial fan as an example to see how to clean the rusted fan:
1. Physical methods to remove rust
Comparison The commonly used and relatively simple method is to polish. This method requires some effort and the rust can be rubbed away, but this is not a good method. If you are more concerned about the impact of polishing on the appearance of the industrial fan, it is recommended to avoid this method, or If you don't care about the appearance, you can choose this method to polish it with confidence. This can be done with steel wool, sandpaper or a wire brush, or if you don't have these you can also use some crumpled tinfoil. If a large industrial fan has a thick layer of rust, you can start with a harder tool like a wire brush and then move to a gentler tool like sandpaper or steel wool as the rust is scraped away so it won't scratch. On the surface of the object, using the right tools and some strength, most of the rust on the industrial fan will be worn away.
2. Chemical rust removal
1. White vinegar rust removal: Common things in the kitchen have highly acidic ingredients that can be used to remove rust. Industrial fans are not like that Smaller items can be soaked in white vinegar. Since it is relatively large, we can try soaking a rag in vinegar and then wrapping it around the item for a few minutes. The method of using white vinegar to remove rust is relatively simple. It is relatively mild and will cause less damage to industrial fans.
2. Lemon rust removal: If you don’t want to use polishing or soaking and prefer natural methods, you can also use lemon juice. Rub some salt on the rusty area of ??the industrial fan and coat it completely. After it is done, pour some lemon juice and let it soak for about two hours. If soaked for too long, the industrial fan may be damaged. After soaking, wipe it and rinse it with water. The biggest advantage of using lemon is that it can not only remove rust, but also will not have a very pungent smell after rust removal, but will have a very refreshing fragrance.
3. Baking soda: Baking soda can not only turn flat dough into delicious and fluffy bread, it is also a versatile item for making toothpaste, can unclog drain pipes, and even remove rust. It's slightly corrosive, so it's better for cleaning rusty things. Pour some baking soda into a bowl and add water until it forms a thick paste. Apply it to the rusty area and let it sit for 2 hours. After that if you want a gentler treatment you can use Scrub with a wire brush, steel wool, or toothbrush, then rinse with water and dry with a cloth.
Causes of industrial fans rusting:
1. Surface contamination: Oil, dust and other corrosive substances attached to the surface of industrial fans are converted into corrosive media under certain conditions. It reacts chemically with certain components in the steel parts, causing chemical corrosion and rust. This kind of pollution and corrosion is relatively common on the surface of industrial fans in some places. Generally, if some oil and other substances are spilled on the surface of industrial fans, it will easily cause corrosion of industrial fans.
2. Surface scratches: Various scratches damage the surface of industrial large fans, reducing the protective ability of steel and easily reacting with chemical media, causing chemical corrosion and rusting. This is for stainless steel. Some large industrial fans will be designed with a layer of anti-rust material on the surface. If this layer of material is scratched by a blunt instrument, the industrial fan will lose its diaphragm from the outside world and the metal will be damaged. It is easy to react with some substances in the air, so large industrial fans are more likely to rust.
3. Moisture contamination: Moisture corrosion is also one of the more common forms of rust in industrial fans. Especially during cleaning, it is easy to leave some moisture in some corners. This moisture will accelerate the wear and tear of industrial fans. of rust. This situation is particularly common in some places where there is a lot of rainy season.
