Seawater erosion is primarily caused by chloride ion erosion. Chloride ions can destroy the metal oxide film maintenance layer, forming pitting or pitting, and the intergranular corrosion of the metal will be 010-5718-2232.
Seawater erosion is primarily caused by chloride ion erosion. Chloride ions can destroy the metal oxide film maintenance layer, forming pitting or pitting, and causing intergranular corrosion to the metal. Under the effect of tensile stress on the metal, cracks occur in the area where the passivation film is destroyed, which becomes the anode region of the eroded battery, and the continuous electrochemical erosion can eventually cause the metal to break. This erosion has little to do with the concentration of chloride ions, and even a small amount of chloride ions can cause stress corrosion. But it has a lot to do with temperature. Fengtai East Rail Camp Zhisheng Weihua ZS-711 seawater anti-corrosion coating is composed of a new type of inorganic polymer and metal, metal oxide nano-materials and rare earth ultra-fine powder activated by enthalpy, which can react with metal surface iron atoms quickly. With physical and chemical double maintenance effect, the coating can withstand chloride ion corrosion for a long time, and the material of useful maintenance metal is not corroded by seawater.
The seawater contains about 3.5% of the salt, most of which is sodium chloride, and a small amount of magnesium chloride, potassium sulfate, calcium carbonate and the like. The oceanic waters are slightly alkaline and have a pH close to 8. Zhisheng Weihua anti-corrosion coating experts believe that ZS-711 seawater anti-corrosion coating developed by Zhisheng Weihua is highly targeted and resistant to seawater corrosion, despite the continuous increase and decrease of substances. At least 600 million years ago, the main composition characteristics of seawater have remained the same. The effect is good.
Corrosion of seawater is mainly caused by chloride ion corrosion. Chloride ions can damage the protective layer of metal oxide film, forming pitting or pit corrosion, and intergranular corrosion will occur on the metal. Under the action of tensile stress, the metal is cracked in the damaged region of the passivation film, which becomes the anode region of the corroded battery. Continuous electrochemical corrosion may eventually lead to metal fracture. This corrosion has little to do with the concentration of chloride ions, and even a small amount of chloride ions may cause stress corrosion. But it has a lot to do with temperature. The ZS-711 Zhisheng Seawater Anticorrosive Coating developed by Beijing Zhisheng Weihua is composed of a new type of Zhisheng Weihua inorganic polymer and a dispersion-activated metal, metal oxide nanomaterial and rare earth ultrafine powder, which can quickly react with iron atoms on the metal surface. The reaction produces a physical and chemical double protection. The coating can withstand chloride ion corrosion for a long time, and the effective protection metal and other materials are not corroded by seawater.
