Steel wire roundness chimney cleaning brush:
Spiral steel pipe rust removal method Mainly use steel wire brush and other tools to polish the surface of the steel to remove loose or raised scale, rust, welding slag and so on. The descaling of hand tools can reach Sa2 level, and the rust removal of power tools can reach Sa3 level. If the surface of steel is attached with strong iron oxide scale, the rust removal effect of the tool is not ideal, and the anchor pattern deep pickling required for anti-corrosion construction can not be achieved. Pickling Derusting Generally, chemical and electrolytic methods are used for pickling. Pipeline anti-corrosion is only chemically pickled, which can remove scale, rust and old coating.
Sometimes it can be used as sandblasting and rust removal. Although chemical cleaning can achieve a certain degree of cleanliness and roughness, its anchor pattern is shallow and it is easy to cause environmental pollution. Spraying (polishing) rusting spray (throwing) rusting is carried out by high-power motor to spray (drow) the blade to rotate at high speed, so that the steel sand, steel shot, wire segment, mineral and other abrasives under the action of centrifugal force on the surface of the steel pipe Spraying (polishing) treatment not only completely removes rust, oxides and dirt, but also achieves the required uniform roughness under the action of abrasive violent impact and friction. After spraying (polishing) and removing rust, not only can the physical adsorption of the surface of the tube be enlarged, but also the mechanical adhesion of the coating layer to the surface of the tube can be enhanced. Therefore, spray (throwing) radiation derusting is the ideal way to remove corrosion from pipelines. In general, blasting (sand) rust is mainly used for the inner surface treatment of pipes, and blasting (sand) rust is mainly used for the outer surface treatment of pipes. There are several problems to be aware of when using blasting to remove rust.China WIRE BRUSH suppliers
