The iron bucket is rusty, can spraying paint directly on the surface without polishing off the rust

It can prevent rust, and the cause of rust is contact with oxygen, and a thick layer of paint can make the iron pass.

It is isolated from the outside oxygen, but the paint will appear uneven, and the color and luster are not very beautiful. If you apply it after sanding, the aesthetics will be better.

Other treatments.

1. Ammonium sulfate.

Liquid rust removal: use 1 kg of ammonium sulfate and 20 kg of water, stir and dissolve, put the rusty iron bucket into it, soak the rust according to the degree of rust and automatically fall off, and the light rust will fall off with a cloth wipe. Then rinse off with clean water. Re-soak in lime milk.

Medium or coated with rosin.

Gasoline liquid rust prevention.

2. Rosin gasoline liquid rust prevention: 50 grams of rosin powder, add 50 grams of gasoline, mix and stir well to become rosin oil. This liquid is applied to iron farming tools that are not rusted, and after drying, it can prevent rust.

3. Vinegar rust removal: put the rusty small farm tool parts and accessories into the vinegar solution and soak them until the rust layer is easy to peel off, remove the rust with a wire brush, and then put them into the vinegar to soak for two or three minutes, take them out, wipe them and dry them.

4. Baking soda.

Water rust removal: Use a jar to hold an appropriate amount of rice washing water.

Add baking soda in the ratio of baking soda to water 1 500, stir well and put in the farm tool parts. After a few days, it will ferment and bubble, and a layer of rust will float on the surface of the water. Remove the parts and wipe them dry.

5. Lime milk rust prevention: burn through the lime, melt it with a small amount of water, add an appropriate amount of water to make lime milk, and immerse the iron farm tools in the lime milk.

Yes. As long as the paint is applied evenly and the metal is not exposed, it can be stopped. The rust itself prevents further oxidation to some extent.

It can stop the rust from continuing to grow, but the effect of painting in this way is not good and it is easy to fall off.

No, rust has gaps in the void and can continue to rust with water and air.

If the iron plate is not rusted and painted directly, it will continue to corrode, and if the anti-rust paint is not flat and viscous enough, it will not be able to isolate oxygen corrosion, and then it will not be able to cut off the chemical reaction of drinking water, so it will continue to rust.

The chemical reaction between the acidic solution (or alkaline solution) and the rust layer on the metal surface is used to dissolve, peel off and be removed.

There are also a variety of active agents and friction agents in toothpaste, for some jewelry oxidation and rust, especially silver jewelry black rust can be rubbed with toothpaste to remove rust.

The adhesion flatness and viscosity of the anti-rust paint are not enough, and it cannot isolate oxygen corrosion, and it cannot be cut off from chemical reaction with water, and it will inevitably continue to corrode!

No, he's already covered up, and he can be isolated.

When painting, you need to scrape off the original rust, because the rust will reduce the adhesion of the paint, so the sprayed paint is easy to fall off, so it is recommended to use sandpaper to polish off the original rust before painting.

Precautions for painting.

1. Before spraying, it is necessary to check whether the air pressure of the spraying is normal, and ensure that the filtration system is clean;

2. Check the air compressor and the water dust separator in the oil spray booth to keep the paint hose clean.

3. Spray guns, painting hoses and paint mixing tanks should be stored in a clean place;

4. In addition to dusting with a blow gun and a sticky dust cloth, all other pre-spraying processes should be completed outside the paint room;

5. Only the spraying and baking process can be carried out in the paint room, and the door of the paint room can only be opened when the vehicle enters and exits, and the air circulation system must be activated when the door is opened to generate positive pressure to ensure that the dust outside the room can not enter the room;

6. You must wear designated spray clothing and safety protective equipment to enter the paint room for operation 7. When baking operations, you must take out the flammable materials in the paint room outside the room;

8. Non-essential personnel are not allowed to enter the paint room.

The original rust must be treated well, otherwise it will be wrapped and peeled off after painting, and the rust can be sanded out with gauze.

Iron spray anti-rust paint can prevent rust.

Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion of the atmosphere, seawater, etc. It is mainly divided into two categories: physical and chemical antirust paint.

The former relies on the proper combination of pigment and paint to form a dense paint film to prevent the invasion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc. The latter relies on the chemical rust inhibition effect of antirust pigments, such as red dan, zinc yellow antirust paint, etc. It is used for rust prevention of bridges, ships, pipelines and other metals.

The first choice is to remove rust thoroughly, and then spray anti-rust primer, such as Zhangdan anti-rust paint, iron red anti-rust paint (the most common two anti-rust paints on the market), and finally brush the topcoat, gray paint or silver powder (galvanized topcoat) as needed. Generally, the anti-rust primer needs two layers, and the sprayed car is too high-end.

It's best to go to the place where the car is repaired, because they have to be treated after spraying, I have seen their paint booth, the equipment is very large, it is a vehicle spray, if you do not affect the part, it is best to pass it once in the future.

Problem description: The iron oil drum has not been used for a long time, and it is rusty inside.

The gasoline poured out was all black and unusable. How to remove rust?

Analysis: Rosin gasoline liquid rust prevention 50 grams of rosin powder, add 50 grams of gasoline, mix and stir well to become rosin oil. This liquid is applied to iron farming tools that are not rusted, and after drying, it can prevent rust.

Lime milk rust prevention Burnt lime with a small amount of water, add an appropriate amount of water to make lime milk, and soak iron farm tools into lime milk.

Ammonium sulfate liquid rust removal Use 1 kg of ammonium sulfate and 20 kg of water, stir and dissolve, put the rusty iron farm tools into it, soak the rust according to the degree of rust and automatically fall off, and the light rust will fall off with a cloth wipe. Then rinse off with clean water. Then soak it in lime milk or coat rosin gasoline liquid to prevent rust.

Vinegar rust removal Put the rusty small farm tool parts and accessories into the vinegar solution and soak them until the rust layer is easy to peel off, remove the rust with a wire brush, and then put them into the vinegar to soak for two or three minutes, take them out, wipe them and dry them.
