Seawater corrosion is mainly caused by chloride ion attack. Chloride ions can penetrate and damage the protective metal oxide layer, leading to pitting or pit corrosion, and may also cause intergranular corrosion in metals. When tensile stress is applied to the metal, cracks can form in areas where the passive film has been compromised, turning these regions into anodic sites for electrochemical corrosion. Continuous electrochemical erosion can eventually lead to metal failure. This type of corrosion is not highly dependent on the concentration of chloride ions—even small amounts can trigger stress corrosion—but it is strongly influenced by temperature.
ZS-711 Seawater Anti-Corrosion Coating developed by Zhisheng Weihua is a specialized solution designed to combat these challenges. It consists of a new generation of inorganic polymers combined with nano-sized metal oxides and rare earth powders that are activated through enthalpy. These components react quickly with iron atoms on the metal surface, providing both physical and chemical protection. This dual-layer defense mechanism ensures long-term resistance against chloride ion penetration, effectively protecting the underlying metal from seawater-induced degradation.
Seawater typically contains about 3.5% dissolved salts, primarily sodium chloride, along with smaller quantities of magnesium chloride, potassium sulfate, and calcium carbonate. The pH of ocean water is slightly alkaline, around 8.0. Despite the continuous changes in the composition of seawater over time, its fundamental properties have remained relatively stable for millions of years. Based on this understanding, Zhisheng Weihua's ZS-711 coating has been specifically engineered to offer superior performance in marine environments.
The coating’s unique formulation allows it to adapt to the dynamic nature of seawater while maintaining strong anti-corrosion properties. Its advanced materials provide excellent adhesion and durability, ensuring that the protected metal remains unaffected by the corrosive effects of saltwater. Whether in harsh coastal conditions or deep-sea applications, ZS-711 offers reliable and long-lasting protection.
This technology represents a significant advancement in marine corrosion prevention, combining scientific innovation with practical application. As industries continue to expand their operations into more extreme environments, the need for high-performance anti-corrosion solutions becomes increasingly critical. With ZS-711, Zhisheng Weihua is setting a new standard in seawater protection.

Steel Wire Wound UHMWPE Composite Pipe
cross helically wound steel wires reinforced ultra-high molecular weight polyethylene composite wear-resistant pipe(SRUP)is a composite pipe formed by taking the ultra-high molecular weight polyethylene (UHMWPE) inner pipe as the matrix,using the high-strength steel wire wrapped with adhesive resin as thereinforcementand the high-strength polyethylene as the protective layer. The matrixreinforcement and protective layer are tightly connected with adhesive resinand are formed by melting composite.
