According to authoritative chemical knowledge, zinc is a metal that is difficult to corrode. When the zinc is heated to the surface of the steel, it can prevent corrosion and rust when it is just exposed to moisture and oxygen in the air; in addition, zinc is also a kind of metal. This kind of material can increase the smoothness, so many zinc steel fence manufacturers use this method to prevent the steel from being oxidized.
Zinc steel can prevent corrosion and provide a layer of zinc protective film for metal. Conductive metal material repair and color-increasing care agent; safe and reliable double protection, synthetic metal resin protective layer and cathodic protective layer, can resist bad weather, Suitable for long-term protection of metal; excellent resistance to corrosion by salt and water. Strong adhesion to all kinds of metals and their alloys, can be directly sprayed without primer, high temperature resistance, not afraid of baking, after drying, the coating can withstand high temperature of about 120 ℃. The anti-drying temperature can reach 80℃, and it dries quickly. Economical and practical, it can prevent rust with one spray.
The anti-corrosion function of zinc steel fence is not only based on the zinc content in the zinc coating, but also affected by the size of the particles in the zinc layer. The smaller the zinc particles, the higher the density of the coating, and the higher the quality of the coating is like a layer of 100% high-temperature hot-dip coating. The function of these fine particles is to make the coating tighter, not only can prevent corrosion, but also can become a coating less than or equal to 120μm (vertical surface) to prevent the volatilization of zinc components. Under general conditions of use, the anti-corrosion time in the atmosphere can reach more than 30 years.
