A good way to remove rust from iron sheets? What is a good way to remove rust from iron

Sandblasting and shot blasting can also be used, see the following instructions for details:

1. Small pneumatic or electric rust removal. It is mainly powered by electricity or compressed air, equipped with appropriate rust removal devices, and carries out reciprocating motion or rotary motion to meet the rust removal requirements of various occasions. Such as angle grinder, wire brush, pneumatic needle beam deruster, pneumatic knocking rust hammer, tooth type rotary deruster, etc., belong to semi-mechanized equipment, the tool is lightweight, maneuverable, can remove rust and old coating more thoroughly, can carry out hair treatment on the coating, the efficiency is greatly improved than manual rust removal, up to 1 2m2 h, but can not remove the oxide scale, the surface roughness is small, can not achieve high-quality surface treatment quality, the work efficiency is lower than the jet treatment.

It can be used in any part of the body, especially in the process of ship repair.

2. Shot peening (sand) rust removal. It is mainly composed of particle jet erosion to achieve surface cleanliness and suitable roughness, and the equipment includes open shot peening (sand) rust removal machine, closed shot peening (sand chamber), vacuum shot peening (sand) machine. The open shot blasting (sand) machine is widely used, which can completely remove all impurities on the metal surface, such as oxide scale, rust and old paint film, with a high rust removal efficiency of 4 5m2 h, a high degree of machinery, and rust removal.

However, because the abrasives generally cannot be used, it has an impact on other operations, and it is troublesome to clean up the site. Therefore, the environmental pollution is heavier, and the use has been gradually restricted recently.

3. High-pressure water abrasive rust removal. The impact action of high-pressure water jets (plus the grinding action of abrasives) and water skid are used to destroy the adhesion of rust and coating to steel plates. It is characterized by no dust pollution, no damage to the steel plate, and greatly improves the rust removal efficiency, which can reach more than 15m2 h.

However, the steel plate after rust removal is easy to return to rust, and it is necessary to coat a special wet derusting coating, which has a great impact on the coating of general performance coatings.

4. Shot blasting and rust removal. Shot blasting is the use of high-speed rotating impeller to throw abrasive to the surface of steel to achieve the purpose of rust removal, is a more advanced mechanical treatment method for hull steel rust removal, not only high production efficiency, but also low cost, high degree of automation, can realize assembly line operation, less environmental pollution, but only indoor operation.

Rust can be removed with oxalic acid. It is sold at the chemical store! You can also use vinegar scrubbing to try, my classmate said it was okay to use it when I was in my hometown before.

You remove the rust from the top first and then apply the paint, which will prevent rust. Give it a try.

Diesel is also OK, soaked with diesel.

Iron products are easy to have rust stains in the process of long-term use, which greatly affects the aesthetics and service life, so timely rust removal has become crucial. Here are a few proven and great ways to do this:

1.Use white vinegar and baking soda.

Mix baking soda and white vinegar together in a ratio of 1:2, evenly coat the mixture on the surface of the ironwork, then scrub it with a wire brush or sponge, and finally dry it with a washed dry cloth. This method has a remarkable effect on rust removal and can also provide protection for iron products.

2.with fine sand and lemon.

Mix lemon juice and fine sand to make a paste-like shape, then evenly apply the mixture to the surface of the ironwork, slowly rotate on the surface, cover the surface with a layer of sand film with a brush, and rinse it with cool water to remove the rust. This Minsen potato seed method is more effective than the larger iron products, and it is easy to use.

3.Use a professional rust remover.

There are many rust removers on the market, just apply them evenly to the surface of the ironwork, let it sit for about 10 minutes, and then scrub it with a wire brush. This method has a rapid and long-lasting effect on rust removal, but it requires a corresponding cost.

4.Use the pickling method.

The pickling method is to use acidic medium to chemically react the rust on the surface of iron products to achieve the purpose of rust removal. Phosphoric acid or nitric acid is usually used, applied to the surface of iron products, left for about 20 minutes, and then rinsed off with cool water. However, the use of the pickling method will cause a certain degree of pollution to the environment, and you need to pay attention to safety issues, so you need to get professional help.

In short, rust removal is a routine job, each method has its own specific scope of application, and deciding which method to use also needs to take into account factors such as the material of the iron product, the degree of rust, etc. Especially when using chemical agents for rust removal, it is important to pay attention to safety precautions.

1. With quicklime, quicklime and iron produce a chemical reaction to generate iron hydroxide to produce precipitation.

2. The rust on the tile can be washed and removed with 2 oxalic acid solution, and then wiped with water. After grinding 3-4 vitamin C tablets into powder, sprinkle them on the surface of the floor tiles, and then scrub them with water several times to remove rust stains. If it is rust stains, you can use 10 oxalic acid and citric acid to add water mixture to soak the rusty area, and then rub it again with concentrated salt water.

If you have fresh lemons, you can squeeze out the juice and drop it on the rust stain and rub it by hand, repeat several times until the rust stain is removed, and then wash it with soapy water.

3. The rust on the bicycle handlebar should be bought on the market to buy some hydrochloric acid, which should be dilute and can also be rusted.

Carbonated drinks can be used to remove rust, soaking rusty metal in carbonated drinks, and the iron oxide in the rust can react with the acidic substances in carbonated drinks, so it has the effect of removing rust. Sour tomatoes can also be rusted, and the juice of tomatoes can be removed by applying the juice to the rusty area. Rust can also be removed with the friction of fine sand.

The main ingredient contained in rust is iron oxide, while carbonated drinks contain acidic components such as citric acid and carbonated water. Iron oxide and acids can react chemically to remove rust. Prepare a bottle of cola or other carbonated drink, soak the rusty metal in the carbonated drink, and you can see the two react, forming bubbles, and when the reaction stops, the rust can be removed.

Tomatoes taste sweet and sour, and the acids in them can react with rust. Cut the tomatoes, apply the juice to the rusty area of the metal, and after a few minutes, rub it again and the rust will be removed. The more sour the tomatoes, the better, and of course after rubbing the rust, the tomatoes can no longer be eaten.

Wet the peel of a potato or radish and rub it with a layer of fine sand and rub it on the rusty metal. Fine sand strengthens friction and removes rust with friction. You can also use the steel wool ball at home to scrub the rust, but this will scratch the scratches, and the more valuable metal should not be used.

1. Soak the stained area with aged vinegar.

2. After diluting with disinfectant, soak it a little and try it, but you must master the dilution ratio and soaking time.

3. Potassium permanganate and acetic acid, the practice is to dissolve a little potassium permanganate in water first, and then put the clothes to be rinsed in, to be fully soaked, after soaking for 10 to 20 minutes, the clothes will be dark red, pick up the clothes, wash the water; Then dissolve a little acetic acid in water, and put the clothes soaked in potassium permanganate into the acetic acid solution, the clothes will slowly change from dark red to the original disgusting color, and the dyed places will also fade away without damaging the original color of the clothes. Sometimes you can also use this method when wearing yellowed clothes.

4. Add laundry detergent and dish soap containing anionic surfactant to warm water 1:1, soak the dyed place in warm water for more than half an hour, and then scrub it with your hands. If it is still not clean, put all the clothes in water above 50 degrees, add a small amount of laundry detergent to scrub, and use the fading of the clothes to reduce the color difference of the dyeing.

Items made of iron sheets are particularly prone to rust in daily life. If you want to prevent rust, you can directly use a cotton cloth dipped in a little rust oil, or the oil in the sewing machine, and wipe it on the surface of the iron sheet, which can be effectively prevented. It has to be said that this method is one of the most common and widely used.

01 For friends, if the iron filing cabinet already has rust spots, at this time we can use cotton yarn to dip a certain amount of oil and apply it to the rust spots, which can also effectively remove the rust.

02 In order to effectively prevent rust on items made of iron sheets, we can directly apply a layer of wax on the surface of items made of iron sheets for protection. In this way, the metal surface can be isolated from moisture.

03 However, when some friends want to remove the spicy surface of the iron sheet, they should directly clean it with hot water. In fact, it is a safe, environmentally friendly, and rust-resistant material.

04 If you have found that there are rust spots on the surface of the items made of iron sheets, do not use sandpaper or rough surface to polish them at this time. Once polished, the surface of the item may be damaged, and the use time may be shortened.

1. White vinegar. You can soak the rusty iron sheet products in white vinegar for about a few hours, and then use a clean rag to wipe the rusty area of the iron sheet clean. If the fake pie is like a large iron product, then you can directly apply some white vinegar to the rusty area, and then use a rag dipped in some white vinegar to wipe the rusty area continuously.

When the white vinegar touches the rust on the iron sheet, it will produce a chemical reaction that can decompose the rust on the iron sheet.

2. Lime and salt. You can sprinkle some salt on the rusty area of the iron sheet, so that the rust is evenly covered by the salt, then squeeze the orange into juice, then pour the orange juice on the rusty position of the iron sheet, and then wait for about three hours, and finally use a brush to continuously brush the rusty position of the iron sheet. If there is still rust left, you can use the outer skin of the orange to wipe the remaining rust constantly, and the rust can usually be wiped clean.

3. Oxalic acid. You can use detergent to clean the rusty area of the iron sheet first, and you need to wipe it dry. Then dilute oxalic acid and water together according to a certain ratio, then soak the rusty iron sheet products in the diluted solution, wait for about 20 minutes, and finally use a brush to continuously brush the rusty area.

It is recommended that everyone must wear gloves and masks when operating, so as to avoid oxalic acid causing harm to themselves.

4. Baking soda. First dilute baking soda and water together according to a certain ratio, then apply the diluted solution to the rusty position of the iron sheet, wait for about half an hour, then use a brush to continuously scrub the rusty area, and finally use water to rinse the rusty area.

There are many ways to deal with the dust circle of iron sheet rust, and you can choose the appropriate treatment method according to the actual rust situation of iron sheet, so as to improve the rust removal efficiency of iron sheet.
