From the view of the effect of coating with multiple layers of mineral grease, there is no rust in the protected part of steel pile, and the anti-corrosion protection effect is excellent. The anticorrosive material coated with mineral grease still maintains the original state, the outer surface of the anticorrosive protective cover is smooth, and the degree of adhesion of Marine organisms is greatly reduced. The anticorrosive belt is intact and tightly adhered to the surface of the steel pile, and the anticorrosive paste is uniformly and completely attached to the surface of the steel pile, basically maintaining the original state, and the oil film is intact as a whole.
