How to prevent rust in the open air workpiece or what anti rust oil to use

The rust prevention of steel is a big problem. Once the composition of the steel is determined, it can only take care of its external environment. First of all, it is very important and effective to keep the environment dry.

Both indoors and outdoors. Outdoor can be covered with a rainproof cloth. Dry in time after the rain and sunny weather.

Secondly, brush with anti-rust paint. The key to this step is to polish the surface of the workpiece clean, and then brush the anti-rust paint, taking care to cover it all. In other words, the quality of construction should be guaranteed.

Other methods, although they are available, are not suitable for your situation. Hope these are helpful to you.

Hard film anti-rust oil also depends on the additives in the anti-rust oil, it is obvious that he uses the amount of film additives is not so much, the cost problem, this is one of the reasons, you can estimate the volume and profit of this customer.

You get what you pay for, the conditions are so harsh, and no matter how strong the anti-rust oil is, you have a great chance of rusting.

In addition, the fact that you have not stored in the warehouse for a year also has something to do with it.

First understand the salt spray resistance of this anti-rust oil and test it.

Before the customer made a large workpiece of the hood also had a similar situation, made to be not painted, to put it for a long time, and then changed the soaking method to do rust prevention, the large workpiece should have a crane, at that time soaking will be soaked a few more times to wait for the workpiece on the moisture can be replaced.

Hard and soft materials are not so difficult to wash, and cleaning agents such as kerosene and solvent oil can be cleaned.

Hope that helps.

Wipe clean and apply diesel, preferably soaked.

If the workpiece is too large......You have to maintain it regularly.

That's all I know about ......

It's better to be galvanized so that it doesn't rust easily, or it's diesel.

Summary. The oil that can be rubbed to prevent rust is butter. Butter is resistant to rust.

However, the anti-rust effect of butter is average; Butter is mainly used to isolate the corrosion of oxygen on the metal surface, and to prevent oxidation reaction by isolating oxygen, it plays a role in preventing rust; Butter is easy to volatilize, especially when exposed, the temperature is high, and the volatilization will be faster when the wind and rain are blowing. It is recommended to paint the nails to prevent rust, or to galvanize the nails, so that the rust protection time will be longer.

The oil that can be rubbed to prevent rust is butter. Butter is resistant to rust. However, the anti-rust effect of butter is average; Butter is mainly used to isolate the corrosion of oxygen on the metal surface, and to prevent oxidation reaction by isolating oxygen, it plays a role in preventing rust and disturbing it; Butter is easy to volatilize, especially when exposed, the temperature is high, and the volatilization will be faster when the wind and rain are blowing.

It is recommended to paint the nails to prevent rust, or sell zinc to the nail plater, so that the rust prevention time will be longer.

Anti-rust oil, the role of anti-rust oil: 1It has a certain viscosity or orange posture, and adheres to the metal surface to form a hard or soft continuous film, so that it is isolated from air and water to prevent steel or non-ferrous metal raw tung wood from rusting.

2.All kinds of anti-rust oil are short-term anti-rust properties, and the anti-rust period can be up to about five years, but if the machinery is reused, the anti-rust film can be washed off with kerosene or stain removal oil at any time, which is different from the anti-rust paint used for permanent anti-rust in the bureau.

Any oil will do, as long as the iron is isolated from the air and not oxidized. Antirust oil The function of antirust agent is to form a firm adsorption film on the metal surface, so as to inhibit the contact between oxygen and water, especially water, on the metal surface, so that the metal will not corrode. Lubricants are mainly used in industrial lubricants, metalworking cooling lubricants, metal protective oils, etc.

As an additive, the rust inhibitor must have sufficient adsorption to the metal and solubility to the oil, so the rust inhibitor is composed of a strong polar group and an appropriate lipophilic group. At present, the following categories are widely used and have good effects: sulfonates (calcium sulfonate, sodium sulfonate dust file and barium sulfonate), carboxylic acid and its salts (dodecene succinic acid, zinc naphthenate, n-oleoylsarcosarcoyl eightetamine salt), organophosphates, imidazoline salts, ester rust inhibitors (lanolin and lanolin soap, sebenzene 60 or 80, oxidized stone grease), heterocyclic compounds (benzotriazole), organic amines, etc.

Water-soluble rust inhibitors mainly include: sodium nitrite, potassium dichromate, trisodium phosphate.

Oh, thanks.

1.Brief introduction.

In the process of production and use of metal products, some problems related to rust collapse will be encountered. Rust will reduce the strength and hardness of the metal, and the surface will be rough and uneven, affecting the appearance and service life. Therefore, in order to prevent and remove rust, people often use various oils to protect metal products.

2.Anti-rust oil.

Antirust oil is a commonly used anti-rust agent, which can form a protective film on the metal surface to prevent oxygen and moisture from invading the metal surface, thereby preventing the occurrence of rust. The main component of antirust oil is polymer, which has good adhesion and water static.

3.Rust removal oil.

Rust remover oil is an industrial solvent used to remove rust from metal surfaces, which can effectively react with rusty substances and dissolve or remove them. The main components of rust removal oil are usually acids, alkalis or some organic reagents, which can quickly decompose rust substances on metal surfaces.

4.Common oils.

In addition to anti-rust and anti-rust oils, there are a number of other oils that can be used to prevent rust on metal surfaces. For example:

Moto oil: Moto oil is rich in various fatty acids and other components, which can effectively prevent oxidation and rust on metal surfaces.

Olive oil: Olive oil has rich protective properties that form a strong protective film that prevents oxygen and moisture from invading metal surfaces.

Edible oil: Some components in edible oil, such as linoleic acid and linolenic acid, can effectively protect metal surfaces and prevent the occurrence of rust.

5.How to use:

Whether it is anti-rust oil or anti-rust oil, you need to pay attention to the following points when using it:

Clean the metal surface to remove oil and impurities.

Prepare the required oil or solvent.

Use a rag, brush, etc., to evenly apply the oil to the metal surface, making sure to cover the entire surface.

Allow the oil to dry naturally or use a hair dryer to speed drying.

6.Precautions.

When using anti-rust oil or anti-rust oil, you need to pay attention to the following points:

Keep it well ventilated during use and avoid inhaling oil vapors.

Anti-sock core rust oil and rust removal oil have a certain degree of corrosiveness, and protective tools such as gloves need to be worn when using.

When using raw materials such as motorcycle oil and edible oil, it is necessary to pay attention to their quality and purity.

7.Epilogue.

In rust prevention and rust removal on metal surfaces, different oils have different characteristics and advantages and disadvantages. Choosing the right oil for your own needs is an important part of the production and use of metal products.

Hello dearNow all of them are used anti-rust oil, or anti-rust spray, anti-rust spray can not only play a role in the anti-rust of the mold car virtual group, but also play a certain role in lubrication on some guide rails, you can also play butter on the surface, remember to clean the previous oil stain before playing butter, I hope it can help you.

1. Anti-rust oil is a temporary anti-rust material, which cannot achieve the purpose of permanent anti-rust, and the general anti-rust oil is at most a 2-year anti-rust period, so if you want to do permanent protection, it is better to use paint, which can reach a rust prevention period of about 10 years.

2. If it is a stored workpiece, it will be reprocessed after a few years, then it is recommended to use anti-rust wax, which can reach 3-5 years of anti-rust period, suitable for long-term anti-rust, and you can also use some imported ion packaging film, which can reach 10 years of anti-rust period when packaged, but it is more expensive.

If you have any questions, please see your ID profile or profile picture.

The principle of anti-rust oil is to isolate the activity of active oxygen between the surface of the object and the air to prevent oxidation, etc., so before applying, the surface of the item should be cleaned up, and no rust, water and the like can be left, so that it can be maintained for a long time, but it needs regular or irregular maintenance and paint repair.

If it is made of stainless steel, it is best to do passivation...

No, you can't! It's best to spray again every once in a while.
