钢结构的防腐措施之热喷铝（锌）复合涂层发布时间：2015-10-12 9:12:31 浏览次数:671
This is a kind of with hot dip zinc anti-corrosion effect is long-term anti-corrosion methods. Particular way is first blast to the surface of steel members, make its surface with metallic luster and MAO. With acetylene and oxygen flame will continue to send the aluminum wire melting (zinc), and use compressed air to blow the attached to the surface of steel members, in order to form honeycomb aluminum (zinc) coating layer thickness (about 80 microns to 100 microns).
Finally or neoprene paint coating with epoxy resin filling wool stoma, to form a composite coating. This law cannot in the lining construction of tubular components, so must do air tightness closed on both ends of the tubular components, so that the internal corrosion. This process has the advantage of size of strong adaptability, component shape size is almost unlimited. To such as is in this way, the construction of gezhouba ship lock. Another advantage is the process of thermal effect is local, controlled, and won't produce thermal deformation.
Compared with hot dip zinc, this kind of method of industrialization degree is low, sandblasting spray aluminum (zinc) the intensity of labor is big, the quality is also affected by the operator's mood changes.
