What is the best way to prevent rust on the screws on power distribution equipment?

It is recommended to use Dacromet screws, which have several times the anti-rust ability than galvanized. ** is cheaper than stainless steel screws.

Generally, due to the requirements of conductivity in power distribution equipment, anti-rust powder will be used.

Although there are many types of anti-rust oil, it is not suitable for your needs, one is that the lubricating anti-rust oil will cause flowing pollution, and the other is that the anti-rust oil of the hard film is non-conductive, and needs to be disassembled, even if it is a multi-functional anti-rust oil, similar to WD40 will have a place where the penetration is not in place, and the conductivity is not verifiable.

Antirust powder is a vapor phase corrosion inhibitor that forms uninterrupted film-forming protection for metals with slow volatilization. And the sachets are pollution-free.

It's good to change a batch of galvanized.

I have here a picture album sent by the manufacturer when purchasing anti-rust oil, there is a product called: multi-functional anti-rust agent FX-40 seems to suit your requirements, the purpose is: the product has anti-rust, lubrication, cooling, cleaning, conductive and other effects, can efficiently maintain all kinds of mechanical equipment, precision instruments, parts.

It can be applied in production, storage, maintenance, repair and other links, and all functions work at the same time to provide perfect maintenance for metal, which is more effective, more convenient, more economical and more time-saving than single-function products, and has great application value.

The brand is Eurasia, we are now using their company's products, all aspects are very good, the above instructions I copied according to the album, you still contact their staff for detailed consultation.

Hello, for fastening screws for anti-rust treatment, can be for different environments, anti-rust time and other factors, can recommend the use of different anti-rust schemes, specific contact professional companies, understand the consultation - Shenzhen Tianchangrun lubricant technology ****, engaged in lubrication and anti-rust more than ten years of rich experience.

with anti-rust wax. Tuffi's DINOL4010, like lacquer, can be self-sprayed in small bottles. Transparent, good-looking, and easy. Long anti-rust time.

Power distribution equipment needs to consider not only the problem of rust prevention, but also whether it will affect the conductivity performance, the current mainstream power distribution equipment anti-rust maintenance is the use of vapor phase antirust powder bag or divergent body, anti-rust effect is good, does not affect the power performance.

If you have any questions, add q to communicate.

Anti-rust think tank, for you to answer.

Antirust agents can also be used to achieve the effect of rust prevention.

It should be treated with stainless steel or Dacromet.

Antirust! Anti-rust paint is recommended! It is recommended to spray anti-rust oil that has rusted

The sealed screws are protected from rust by means of anti-rust packaging, such as wrapping with vapor phase anti-rust materials, coated with anti-rust oil, and sealed with dry air.

Because what you said is not very clear, but I can only answer according to the method I know The screws are divided into materials If it is a sale, it is easy to prevent rust Buy a better anti-rust oil There are two kinds of anti-rust oil One oily and one water-based Personally, I think that water-based is better, but from a visual point of view, oily may be considered the best by everyone Water-based as long as it is sprayed on the screws Oily brushes on the screws with a brush But this oil is 10 liters a barrel (minimum) A few hundred dollars This method is temporary rust prevention A better anti-rust method is galvanizing Galvanizing is also divided into many plating methods The effect of hot-dip galvanizing is the best Or plating other materials can also be used But galvanizing is relatively cheap If you are a screw for your own use, it is recommended to buy stainless steel 316 material is the best material that can be bought on the market I don't know if I can help you (personal explanation, if there is any inconsistency, please forgive me).

There are four general methods of anti-corrosion of metal objects:

1. The use environment of metal;

2. The interface between the material of the metal material itself and the environment;

3. Control the metal material itself;

4. Improve the structural design of the metal itself.

It is possible in real life to isolate the screws, or screws mounted on the components, from any environment that would cause the alloy to corrode, as described above, but it can be very difficult.

Then there is only one way left, the interface between the metal material and the environment. This method of surface corrosion protection is currently the most extensive.

The choice of protective layer should ideally meet four requirements:

1. The structure of the protective layer is compact and complete, and the pores should be small;

2. The protective layer material is corrosion-resistant and wear-resistant, and has high hardness;

3. The protective layer should be evenly distributed on the metal screws and should also have a certain thickness;

4. The protective layer should be able to be firmly combined with metal screws and have good adhesion.

Classification of Protective Layers:

First, metal coating (generally using a strong corrosion-resistant alloy or metal to form a protective layer on the surface of the metal that is easy to corrode). Common methods of processing coatings include electroplating, molten metal immersion (i.e., hot dip plating), and chemical surface treatment.

Second, the non-metallic coating (refers to the use of organic polymer materials (such as paint) or inorganic materials (such as ceramics) to form a protective layer on the surface of metal equipment or parts) can completely isolate the corrosive environment and prevent metal screws from contacting with corrosive substances and causing corrosion.

Through surface treatment, oxidation, galvanizing, Dacromet, phosphating, painting, chrome plating, nickel plating、。。

Metal alloys can be used to form a protective surface coating, i.e. a protective film or chemical conversion film, in a controlled manner in an appropriate chemical solution. Because the surface metal is transformed into a compound and integrated with the underlying metal during chemical treatment, the resistant surface layer is a part of the underlying metal in terms of physical and chemical properties. The protective film is mainly used for:

Improve the stability of the oxide film on the metal surface and prevent further corrosion of the metal or coated metal in the atmosphere. 2.Reduces metal rust to a minimum.

3.Improve the viscosity of paints and coatings. There are three common chemical surface treatments: phosphate treatment, chromate treatment and oxidation treatment.

Blackened, galvanized, coated with anti-rust oil.

What kind of screws are used outdoors to prevent rust? Yu Wenlong, a fastener consultant, believes that if you have a lot of money, a large investment budget, and a good appearance, use stainless steel; Yu Wenlong, a fastener consultant, believes that if you want to save the cost as much as possible, the anti-rust effect is as good as possible, and the thread accuracy is higher, you can use Dacromet; Yu Wenlong, a fastener consultant, believes that if you want to save the cost as much as possible, the anti-rust effect is as good as possible, and the thread accuracy requirements are not necessarily too high, hot-dip galvanizing is used.

Yu Wenlong, a fastener consultant, believes that it is best to check the relevant information by yourself, and it is always fake on the Internet. The light ones are unqualified in terms of product quality, and the heavy ones will be fined. Of course, fastener consultant Yu Wenlong believes that if you have the strength, ask a fastener consultant to refer to your technology, grasp the direction of enterprise development, positioning products, positioning customers is also a good choice.

Stainless steel, or copper-plated.

What is used, only stainless steel.

The simplest is to apply a layer of oil, the cost is relatively low, and the effect is also available.

Two methods:1Oil-free anti-rust is VCI vapor phase anti-rust (VCI anti-rust paper and VCI anti-rust film).

The anti-rust time is 6 months to 3 years. 2.Oil rust prevention, this method is now the most widely used and most common on the market, the rust prevention time can reach 3-5 years according to different oil products, and the longer requirements can reach 7-10 years!

If you need information, you can send a message on the site.

Vapor phase rust prevention can be used, such as packaging with anti-rust paper or anti-rust film, or with vapor phase anti-rust agents. I won't say much about the specific use method, the vapor phase anti-rust is very convenient, and the fixed storage can be 3 to 5 years of rust prevention, which has no effect on your materials. It's more suitable for you.

Other processes are more cumbersome.
