The third generation of coated mineral grease anticorrosion technology adopts a multi-layer compact protection system, the inner mineral grease anticorrosion paste, the middle mineral grease anticorrosion belt, the outer seal and the outer protective layer constitute a whole long-term coating anticorrosion system. The products are green and pollution-free, especially in the Marine pasture area, which can be safely used. The technology is convenient in construction, can be constructed with rust and water, the construction process is simple, the period is short, and the efficiency is high. This technology is mainly applied to the long-term corrosion protection of steel structures in the ocean spray splash area, such as Marine wind power pile foundation, wharf steel pipe pile, bridge foundation and so on.
