The ordinary Expanded Metal Mesh has a service life of 10 years. Some small manufacturers with no scale occupy the market at a low price. In order to reduce costs, the expanded Metal Mesh produced is shoddy. The use time is 3-4 years, which can not meet the requirements at all.
Therefore, when purchasing Expanded Metal Mesh, you must choose a formal and professional manufacturer, and you must not buy products of poor quality at a cheap price. Only in this way can our Expanded Metal Mesh have a longer life.
So how to better improve the rust and corrosion resistance of Expanded Metal Mesh?
①Expanded Metal Mesh protective layer method:
- Refers to covering the surface of the Expanded Metal Mesh with a protective layer to isolate the Expanded Metal Mesh from the surrounding corrosive medium to prevent corrosion.
- Coat the surface of Expanded Metal Mesh with engine oil, petroleum jelly, paint or cover with enamel, plastic and other corrosion-resistant non-Expanded Metal Mesh materials.
- Use electroplating, hot-dipping, spraying and other methods to coat the surface of the steel plate with a layer of Expanded Metal Mesh that is not easily corroded, such as zinc, tin, chromium, nickel, etc. These Expanded Metal Mesh often form a dense oxide film due to oxidation, thereby preventing the corrosion of steel by water and air.
②Expanded Metal Mesh electrochemical protection method:
- The electrochemical protection method uses the principle of the galvanic cell to protect the Expanded Metal Mesh, trying to eliminate the galvanic corrosion that causes the galvanic corrosion. Electrochemical protection law is divided into two categories: anode protection and cathodic protection. The cathodic protection method is more widely used.
- Cathodic protection method: This method is to connect Expanded Metal Mesh (such as zinc or zinc alloy) to the protected Expanded Metal Mesh. When galvanic corrosion occurs, this active Expanded Metal Mesh acts as a negative electrode to cause oxidation reaction, thus reducing Or to prevent corrosion of the protected Expanded Metal Mesh. This method is often used to protect steel piles and shells of ships in the water, such as the protection of steel gates in the water. Usually, several zinc blocks are welded below the waterline of the shell of the ship or on the rudder near the propeller to prevent the hull of the ship. Corrosion.
- Impressed current protection method: Connect the protected Expanded Metal Mesh to the negative pole of the power supply, and select another conductive inert material to connect to the positive pole of the power supply. After being energized, the surface of the Expanded Metal Mesh produces negative charges (electrons) accumulation, thus inhibiting the loss of electrons of the Expanded Metal Mesh to achieve the purpose of protection. This method is mainly used to prevent the Expanded Metal Mesh equipment from corrosion in soil, sea water and river water. Another method of electrochemical protection is called anode protection, which is a process in which the anode is passivated within a certain potential range by applying a voltage. It can effectively block or prevent the corrosion of Expanded Metal Mesh equipment in acids, alkalis, and salts.
- Treat the Expanded Metal Mesh corrosive medium:Eliminate corrosive media, such as frequently cleaning Expanded Metal Mesh equipment, placing desiccant in precision instruments, and adding a small amount of corrosion inhibitor that can slow down the corrosion rate in corrosive media.
