How To Safely Remove Rust In Industrial Manufacturing?
Whether it is in the mechanical design or in the customer’s use, the rusting of metal parts is a headache, and there is no best solution to this problem.
There are many commercial rust removal methods, but most of them are highly toxic and rely on some form of acid such as phosphoric or oxalic acid to do the job. If you use these methods, you must wear rubber gloves and strictly follow the instructions and precautions provided by the manufacturer. This removes rust and protects you from toxic chemicals.
If you want to avoid using toxic chemicals, there are several common household items that can safely remove rust from metal, including white vinegar, baking soda, sandpaper, steel wool, and scouring pads. In addition, there are high-end laser rust removal, which can achieve the rust removal effect and ensure personal safety.
What are the commonly used safe rust removal methods in industrial production? Next, let STYLECNC introduce to you.
Vinegar for Rust Removal
White vinegar can often be used for small items such as earrings. Pour a little vinegar into a glass and give these little things a good soak. When you see the rust has dissolved, simply rinse off the jewelry and dry it with a cloth. You can also apply clear nail polish for long-lasting protection.
Vinegar can also be used on larger items, either by pouring it directly on the item, or laying it down with a cloth, and after the rust has dissolved, wipe off, rinse, and dry if necessary.
Baking Soda for Rust Removal
Baking soda is another way to remove rust from metal. You can make a paste with baking soda and water, make sure the solution is strong enough to have enough paste to adhere to the surface, then spread it out on the metal and let it sit. Once the rust is loose, you can wipe it off, and if the rust is deep, removing them may require another application of such a paste. Baking soda paste can also be used in various other areas of the home, and it is also a good substitute for many household cleaners.
Sandpaper for Rust Removal
Sandpaper, steel balls, and scouring pads are all in one category. If you want to remove rust from metal and don’t mind a little more work, you can try hand-removing rust with sandpaper or other rough items such as sandpaper, steel wool, or scouring pads. However, this may take a while. If the rust area is large, it may take several attempts to remove the rust completely.
Laser Rust Removal
Laser rust removal machine is a type of laser cleaning machine uses a high-intensity laser beam, a short pulse laser and the physical reaction between the rust layer to achieve the rust removal effect. The beam emitted by the laser rust removal gun is absorbed by the rust layer on the surface of the part, and the absorption of large energy forms a rapidly expanding plasma (highly ionized unstable gas), which generates a shock wave. The shock wave shatters the rust and removes it. The light pulse width must be short enough to avoid secondary damage to the treated surface. Laser rust removal has high efficiency, but the price is a bit expensive, and it is generally used in industrial manufacturing.
Rustproof
Of course, the best way to remove rust is to keep metal equipment and parts from rusting. Keeping the metal surface as dry as possible will help prevent rust, because water is an important factor that causes rust. In other places, we can protect it by applying anti-rust oil and other measures. In addition, galvanizing, chrome plating, painting, etc. are also good anti-rust treatment methods. However, prevention is not always effective, especially in areas with high humidity. So it’s best to remove the rust right away, before it starts to eat away at the metal. Remember, the longer the rust is left untreated, the more difficult it will be to remove and the more damage it will be.
