How to make anti corrosion in storage tanks for barium metal

The storage tank for barium metal is a special container that needs to be treated with anti-corrosion to ensure its safety and stability for long-term use. Here are a few ways to protect barium metal tanks from corrosion:

1.Hot-dip galvanizing: The surface of the storage tank is first derusted, and then immersed in molten zinc, so that the molten zinc forms a layer of zinc on the surface of the storage tank, so as to achieve the purpose of anti-corrosion.

2.Thermal spraying: The anti-corrosion coating is heated to a high temperature and then sprayed on the surface of the tank by a high-pressure spray gun to form a strong anti-corrosion layer.

3.Cold spraying: Anti-corrosion paint is sprayed on the surface of the tank to form a strong anti-corrosion layer. This method is suitable for situations where the surface of the tank is relatively flat.

4.FRP storage tank: FRP storage tank is a kind of storage tank with excellent anti-corrosion performance, and its surface is made of glass fiber reinforced plastic, which has the characteristics of corrosion resistance, high temperature resistance, and wear resistance.

5.Stainless steel storage tank: Stainless steel storage tank has excellent corrosion resistance, which can effectively prevent barium metal from contacting with air, water and other substances and chemical reaction, so as to achieve the purpose of anti-corrosion.

In short, the storage tank for barium metal needs to be treated with anti-corrosion to ensure its safety and stability for long-term use. Different anti-corrosion methods are suitable for different tank materials and use environments, and need to be selected according to the actual situation.

Brush anticorrosive paint on it.

It is generally stored in kerosene.

Mainly with paint. You can also wrap the fiberglass cloth again, and then brush the asphalt paint, three oils and two cloths.

It is recommended to use DuPont anticorrosive coatings for the treatment of the inner wall of the storage tank. DuPont anti-corrosion series can protect the surface of substrates under harsh mechanical, chemical and thermal stress erosion from strong corrosion of various chemicals, and the anti-corrosion effect can last for more than 5-20 years; Asplit ASPRIT anticorrosive coating series can resist more than 270 kinds of chemicals, which can meet the anti-corrosion requirements of most customers, and can protect customers' investment to the greatest extent, so that one investment can be used many times!

It is better to use anticorrosive coatings, chlorosulfonated polyethylene primers for primers, and chlorosulfonated polyethylene topcoats for topcoats, which can be referred to**.

If you want to do it once and for all, it's better to lin.

PE material anticorrosive storage tank is resistant to most acid and alkali aqueous solutions (except for strong redox agents) and most organic solvents (except chloroform, aromatic hydrocarbons, halogenated aromatic hydrocarbons, and lower lipid aromatics).

As a commonly used production equipment, carbon steel storage tanks are widely used in chemical production. However, due to the influence of corrosion factors such as certain corrosive medium in the physical properties of carbon steel materials and the use environment, there are different degrees of corrosion in carbon steel storage tanks during use.

Types of corrosion and corrosion of carbon steel tanks:

1.Galvanic cell corrosion (galvanic corrosion). This is one of the most major and harmful forms of corrosion, occurring at the bottom, walls, and top. Electrochemically etched anode zone and cathode 2

The zone is formed due to the potential difference caused by the microscopic heterogeneity of the material itself, and the water, salt, and acid contained in the oil variety are the main causes of electrochemical corrosion.

Shenyang anti-corrosion pressure tank - carbon steel tank processing.

2.Corrosion caused by reducing substances and other bacteria. It occurs mainly at the bottom of the tank.

Corrosion of carbon steel storage tank: According to the relevant information of the wastewater stored in the carbon steel storage tank provided by the customer, the main cause of corrosion is the corrosion caused by water, alkaline substances, salts, raw substances and other bacteria, etc., and the most serious part of corrosion is the aqueous part at the bottom of the tank, because the water at the bottom of the tank contains a large number of inorganic salts with high permeability, which first causes electrochemical corrosion; Secondly, alkaline components are produced after hydrolysis, which causes uniform corrosion and corrosion of welds. In addition, bacteria can grow quickly in the absence of oxygen at the bottom of the tank, which can cause needle-like or filamentous bacterial corrosion.

The carbon steel storage tank with serious corrosion is corroded and perforated in only 3-4 years, and its corrosion characteristics are spots, pits, the maximum perforation diameter is 15mm, the maximum depth is 4-5mm, and the corrosion rate is generally years, up to 2

mm years.

Look at what the tank is used for storage, generally there are 37% hydrochloric acid, 98% sulfuric acid, 65% nitric acid, sodium hypochlorite aqueous solution (12% active chlorine % hydrogen peroxide, 50% chromic acid, glacial acetic acid, silicon tetrachloride, etc.).

Electrochemical corrosion, acid and alkali corrosion, etc.

There are many types of anti-corrosion, such as storage tanks, which are anti-corrosion with rubber or plastic. Iron towers are generally paint-based anti-corrosion.

Ask, you can prevent corrosion without brushing asphalt, and you can brush asphalt in iron drums for transportation!

For ammonia storage tanks, the commonly used anti-corrosion method is to line the interior with FRP or rubber plate. The anti-corrosion effect of the lined FRP is the best, but the cost is higher.

Generally, a layer of FRP is hung for anti-corrosion, and other methods are costly.

1. The chemical industry needs anti-corrosion.

2. Whether it is acid rot or alkali rot.

3. It is mainly a relatively large-scale chemical plant.

4. It is recommended that you look around you first.

Hydrochloric acid, acetic acid, formic acid, propionic acid. These commonly used raw materials should be used in anti-corrosive storage tanks. Such as PP, PO, PTFE-lined PTFE, FPA, ETFE, PPS, etc. The most commonly used is PE.
