Is there a product that can remove rust? What is rust remover used for?

There is a product called rust remover, which is specially used to remove rust, which is convenient and fast, and I will probably introduce it to you:

The main components of Sanhe multi-purpose rust remover are petroleum solvents, special nano rust inhibitors, and imported lubricants, which have strong infiltration and penetration properties, can infiltrate rust and glue scale, and can effectively loosen rust dead parts and remove residual stains of some double-sided tapes. Special molecules can form a protective film on the surface of objects to isolate moisture and air to avoid oxidation and rust. It has strong lubricating properties, eliminates the noise caused by friction of parts, and is widely used in precision instruments, door hinges, iron gates, etc.

How to use:1Shake the product well and insert the catheter; Spray the desired part to prevent backspraying;

2.When dealing with mild rust, first remove the rust and dirt at the junction of the rusted screw and nut, and then use a tool to unscrew the nut with a tool after a few minutes of moderate tapping.

Notes:1This product is pressure packed, do not impact, store in a dry and ventilated environment below 50, avoid direct sunlight, away from fire, heat and high temperature (50) use;

2.Keep out of reach of children by getting splashed or swallowed in eyes;

3.Static electricity must be eliminated before use; This product is strictly forbidden to be exposed to the sun, and the empty cans used up should not be pierced and thrown into the fire;

4.When using, keep the tank upright and the angle between it and the horizontal plane shall not be less than 45 °, so as to prevent the air pressure from being insufficient after spraying.

Waste tank treatment: inverted tank body press the nozzle for about 2 minutes to remove the remaining material, if necessary, you can pull out the nozzle to remove it thoroughly.

If the metal is rusty, you don't have to throw it away and buy a new one, you can use it again if you remove the rust layer. In fact, household products such as tin foil and white vinegar can remove the rust layer, and there are also professional chemical rust removal products. Whichever method of rust removal you use, it takes patience and effort.

But with hard work, a lot of rust stains can be removed.

1. Use white vinegar. Vinegar dissolves the rust layer on the surface of the metal. Soak the rusty metal in white vinegar for a few hours, then wipe off any remaining rust stains.

2Try lime and salt. Sprinkle the salt over the rusty area, then squeeze out the lime juice and pour over the salt. The more lime juice you have, the better, then let it sit for 2 to 3 hours before scraping off any remaining rust stains.

3Make baking soda paste. Add water to the baking soda and mix it into a paste that is thick enough to cover the metal. After applying the baking soda paste, leave it for a while and then scrub it clean.

4. Use potatoes and dish soap. Cut the potatoes in half and soak the cut side in dish soap. They react chemically with the rust layer, making it easier to remove.

Place the potatoes on top of the rust layer and let them sit for a few hours. 5. Use chemical rust removers. There are many chemical products that can remove rust, most of which are made of phosphoric acid or oxalic acid, and they are harmful to the world.

Therefore, before using chemical rust removers to treat the rust layer, it is necessary to take precautions.

Acid, aluminum foil wet, electric derusting machine, etc. can remove rust.

1. Acid: Acid can react chemically with metal oxides in rust to dissolve rust, so that rust can be removed. Acids can be selected from common in life, such as acetic acid, dilute hydrochloric acid, oxalic acid, etc.

2. Aluminum foil wetting: Dip some water with aluminum foil and rub the rusty part to remove rust. Because the reduction potential of aluminum is higher than that of iron in steel, oxygen is transferred from iron atoms to aluminum atoms.

The hardness of aluminum foil is smaller than that of steel, so it will not scratch the surface, and the alumina core formed after aluminum oxidation has a high hardness, which can just be used for steel polishing.

3. Electric derusting machine: electric derusting machine derusting is a commonly used mechanical derusting method. It not only has a good rust removal effect, but also has high efficiency.

There are two types of electric descaling machines: stationary and mobile. The fixed derusting mechanism is simple to make, mainly using a low-power motor as a power to drive the disc wire brush.

The principle of rust removal is the same for both solvents, both of which are used to remove rust by hydrolysis to produce acid, as follows:

1. NH4Cl dissolves in water and reacts: NH4Cl+H2O=NH3·H2O+H(+)Cl(-).

After the hydrogen ion is generated, it reacts with rust: 6H(+)Fe2O3=2Fe+3H2O. So that the rust falls off.

2. Zinc chloride dissolves in water and reacts: ZnCl2+H2O=H(+)ZnCl2(OH)](

In the same way, it reacts with rust and causes the rust to fall off.

Qinqin is happy to answer for you: Can the rust remover sold on the platform really remove rust? A:

The rust remover sold on the Qinqin platform can really remove rust Oh rust remover (metal surface passivator) is a new type of water-based rust remover based on metal chelation passivation technology, which can realize the four functions of rust removal, passivation, rust prevention and primer in one step, and is suitable for traditional phosphorus molding is not easy to operate large machinery lack of rust and phosphorus before painting. At present, it has been widely used in metal processing industry, automobile manufacturing industry, heavy machinery manufacturing industry, metal building materials industry.

Methods of rust removal:

Manual rust removal: mainly with hand hammers, shovels, knives, wire brushes, coarse abrasive cloth (paper), to treat the metal surface with rust.

Power tool rust removal: also known as semi-mechanical rust removal, mainly using air (electric) brush wheel or various rust removal machines to treat the rusted surface.

Jet or projectile rust removal: also known as sandblasting rust removal, mainly with the help of oil-free compressed air (or high-pressure water).

Chemical rust removal: also known as pickling and rust removal, mainly using inorganic dilute acid solution to brush (spray) and soak with rusty metal surface.

Rust remover: It is mainly a method of brushing or soaking on the rusty metal surface with a weakly acidic chemical liquid (i.e., rust remover) to remove the rust on the metal surface through chemical reaction.

Introduction to the rust removal grade:

The standard for steel surface corrosion and rust removal grade is the national standard GB8923-88 "Steel Surface Corrosion Grade and Rust Removal Grade before Painting".

The standard divides the rust removal grade into three types: jet or projectile rust removal, manual and electric descaling, and flame descaling.

Jet and projectile rust removal, denoted by the letter "sa", are divided into four grades:

1) The standard for steel surface corrosion and rust removal grade is the national standard GB8923-88 "Steel Surface Corrosion Grade and Rust Removal Grade before Coating".

2) The standard divides the rust removal grade into three types: jet or projectile rust removal, manual and electric derusting, and flame descaling.

3) Jet and projectile rust removal, denoted by the letter "sa", divided into four grades:

SA1 – Mild post-jet projectile rust removal. There is no visible grease, dirt, unstable oxide scale, rust, paint coating and other attachments on the surface of the steel.

SA2 – Thorough jet or projectile rust removal. There is no visible grease and dirt on the surface of the steel, and the oxide scale, rust and other attachments are basically removed.

SA21 2 – Very thorough jet or projectile rust removal. There is no visible grease, dirt, scale, rust, paint coating and other buildup on the surface of the steel, and any remaining traces are only slight stains in the form of dots or strips.

SA3 – Jet or projectile rust removal for a very clean steel surface. The surface of the steel is free of visible grease, dirt, oxide scale, rust, paint coating and other buildups, and the surface shows a uniform metallic color.

Manual rust removal grade, indicated by ST letters:

1) ST2 Thorough hand and power tool rust removal.

The surface of the steel should be free of visible grease and dirt, and free of build-up such as scale, rust, and paint coatings that are not firmly attached.

2) ST3 very thorough hand and power tool rust removal.

The surface of the steel should be free of visible grease and dirt, and free of build-up such as scale, rust, and paint coatings that are not firmly attached. Rust removal should be more thorough than ST2, and the surface of the exposed part of the substrate should have a metallic luster.

Surface treatment is the key to achieving good coating results. The investment in surface treatment is well worth it. Therefore, the choice of surface treatment method and paint matching system must be carefully considered.

It is important to measure the degree of surface treatment according to international standards, such as the Swedish standard: SIS055900 or ISO08501.
