Vacuum zinc furnace

Zinc percolation is mainly used in iron matrix materials. The artifacts, zinc powder and packing in the barrel for rolling, and heating to 350 ~ 350 ℃, about 3 ~ 12 hours can obtain permeability layer.

Vacuum infiltration of zinc furnace by heating zinc and iron atoms diffusion in the steel surface to form uniform zinc alloy layer of surface protection technology, thus reduced in the process of production of zinc oxide, thus reducing the dosage of zinc greatly reduces the cost of zinc impregnation, compared with hot galvanizing for hot dip galvanized with zinc roughly one-third, the technology is vacuum zinc impregnation technology development again and again and again. It is widely used in power, communication, construction, railway, highway system, shipbuilding industry, petrochemical industry, water heating, hardware and other fields.

The characteristics of vacuum zn:
The coating thickness is homogeneous and can be controlled accurately. The thickness of the infiltration layer depends only on the heating temperature, which is independent of the status of the component and its different position. Complex components such as threads, internal walls or grooves are almost identical in thickness.

The bonding strength of the infiltration layer and matrix metal is high. Thermal diffusion coating is a combination of diffusion metallurgy. It is difficult to peel off the infiltration layer. Only chemical methods can be used to remove it. The tensile strength of the permeability layer and the female material interface: 600-700mpa; The tensile strength of the surface layer is 300-350Mpa.

Vacuum zinc impregnation is done in an airtight container in the heating process, completely eliminates the zinc steam to the atmosphere pollution, completely ended the operators in the process of hot dip galvanized zinc vapor poisoning and the history of high-temperature liquid zinc burn. In the state, the zinc oxide is weakened and the production cost is reduced. The large characteristic of the zn layer is uniform thickness and excellent corrosion resistance.
