A method of anti corrosion acid and alkali resistance of metal containers

Metal containers are a common tool for storing and transporting items, but since metal containers are susceptible to acid-base corrosion, there are ways to prevent corrosion. Here are a few common ways to prevent corrosion (acid and alkali resistance) of metal containers:

1.Surface coating: Apply a layer of anti-corrosion coating, such as epoxy resin, polyurethane, etc., to the surface of the metal container. These coatings form a protective film that blocks the erosion of metals by acids and alkalis, thereby extending the life of metal containers.

2.Anti-corrosion coating repair: Regularly check whether the coating of the metal container is damaged or broken, and repair it in time. If the coating is found to be peeling or peeling, the damaged part should be removed in time and the anti-corrosion coating should be reapplied to maintain the integrity of the coating.

3.Electroplating treatment: The metal container is electroplated, which can form a protective metal film on the metal surface, such as galvanized plating, chrome plating, etc. These metal films can effectively prevent the erosion of metals by acids and alkalis, and improve the corrosion resistance of metal containers.

4.Choose the right metal material: When choosing a metal container, you should choose the right metal material according to the nature of the items you are storing or transporting. For example, for acidic substances, it is not advisable to choose iron containers, but stainless steel containers that are not easily corroded by acids.

5.Cleaning and maintenance: Regularly clean and maintain the metal container, and remove the dirt and corrosion on the surface of the container in time to avoid its erosion of the metal. At the same time, some preservatives or rust inhibitors can also be used for protection to increase the corrosion resistance of metal containers.

In summary, the anti-corrosion (acid and alkali resistance) methods of metal containers include surface coating, anti-corrosion coating repair, electroplating treatment, selection of suitable metal materials, and regular cleaning and maintenance. By taking these methods, you can effectively extend the service life of metal containers, improve their corrosion resistance, and ensure the safety of stored and transported items.

1) Plated with a layer of aluminum or titanium.

2) Coated with a layer of polytetrafluoroethylene (Teflon).

It is enough to use inert metals such as copper directly, which are acid and alkali resistant.

The material can be painted or placed in a dry place.

Metal anti-corrosion methods.

There are many ways and means to prevent metal corrosion, mainly the following:

1. Improve the intrinsic corrosion resistance of metal materials.

It is an effective anti-corrosion method to use metal and alloy materials that are not easy to react with the surrounding medium to process products. For example, some metals and alloys are not easy to oxidize in the air, or can form a dense passivation film, which can resist acid, alkali and salt corrosion, such as stainless steel, that is, a quantitative amount of chromium, nickel, titanium and other elements are added to the steel, and when the chromium content exceeds 12, it can play a role in stainless steel. Some are not easy to corrode in the air, such as aluminum, zinc, etc. The way to obtain this metal material is mainly to change the chemical composition of the metal by smelting methods, such as adding nickel, chromium, silicon, manganese, vanadium and other elements to carbon steel to make corrosion-resistant alloy steel.

Stainless steel is a high-alloy steel that contains more chromium, nickel, titanium and other elements. Corrosion-resistant low-alloy steel is a low-alloy corrosion-resistant steel made by adding trace amounts of vanadium, titanium, rare earth and other elements to the steel. In addition, for some metal materials, the metallographic structure of the metal can also be changed through heat treatment to improve the corrosion resistance.
