Most of the requirements were to maintain the original appearance of the building. When determining the type of stainless steel plate to be selected, the most important thing to consider in the air duct is the required aesthetic concept standard, the place of gas erosion and the elimination management system to be adopted. But do not know, other applications are more and more just to find the consistency of the structure or water absorption capacity. For example, the roof and axillary angles of commercial buildings. In this type of application, the owner's construction costs may be more important than aesthetic concepts. Cold tie electric air valve manufacturers, the surface is not very clean. The use of 304 stainless steel plate in dry indoor air quality is expected to be very good.
Hot dip galvanizing refers to the surface coating of metal composite materials, aluminum alloy profiles or other raw materials with a layer of zinc to play a unique style, rust prevention treatment solution and other functions of the surface treatment. The important method is hot-dip galvanizing.
Zinc dissolves in acid and can also melt alkali, so it is called bimetallic composite material. Zinc does not cause most of the transformation in the dry vapor body of FRP ventilation ducts. In a moist vapor, the zinc coating is converted into a dense basic zinc carbonate film. In the atmosphere containing sulfur dioxide, hydrogen chloride and Marine atmosphere, the corrosion resistance of zinc is poor. In the atmosphere containing sodium citrate at high temperature, high temperature and low temperature, the zinc coating is easy to be corroded. Zinc standard electrode potential is -0.76V, central air conditioning ventilation pipe for stainless steel plate basically speaking, zinc coating belongs to anodic oxidation processing coating, it is suitable to prevent corrosion of stainless steel plate, its safety characteristics and coating thickness is very important. Zinc coatings, passivated by stainless steel, colored or coated with light protectors, can significantly improve their protection and art Deco design.
