PE pipes are widely used in our daily lives and have played a certain role in our lives. In order to better use and maintain this product, it is necessary for everyone to understand the erosion knowledge of the product.
1. Chemical erosion: It is the damage caused by the pure chemical effect between the metal surface and non electrolytes. That is to say, the melting process of metal ions caused by direct contact between metal and medium occurs on the surface of the metal, with a slow erosion rate. The erosion of steel in air or soil belongs to this situation.
2. Electrochemical erosion: Damage caused by the electrochemical effect between the metal surface and the ion conductive medium of the PE tube. That is, the metal electrolysis process that occurs in the primary battery composed of metal and electrolyte. Any erosion reaction carried out according to electrochemical mechanisms includes at least one anodic reaction and one cathodic reaction, which are connected by the electron flow flowing through the interior of the metal and the ion flow in the medium.
3. Bacterial erosion: The mechanism of bacterial erosion on steel is relatively complex, but in some soils, there are three types of bacteria involved in the erosion process: sulfate oxidizing bacteria, sulfur oxidizing bacteria, and iron oxidizing bacteria.
