This is a very long-term corrosion protection method ,the effect eaquel to hot dip zinc. This is done first on the surface of steel components for sand-blasting to the surface exposed metallic luster and beat hair. Then acetylene - oxygen flame will continue to send the aluminum (zinc) wire to melt and blowing with compressed air attached to the surface of steel members to form a honeycomb of aluminum (zinc) coating layer (thickness of about 80μm ~ 100μm). Finally, epoxy resin or neoprene rubber paint and other coatings filled pores to form a composite coating. This method can not be carried out in the inner wall of tubular, which must be done at both ends of tubular member closed airtight, so that the inner wall will not corrode. This process has the advantage of adaptability of the component size, component size and shape is almost unlimited. Gezhouba large as the lock construction in this way also. Another advantage is the heat of this process is local, bound, and thus will not produce thermal deformation. Compared with hot-dip zinc, lower level of industrialization , sand blasting spray aluminum (zinc), labor intensity, quality is also vulnerable to changes with the operator's emotional impact.
