Application of sandblasting gun equipment on pipe inner wall and surface treatment method
The sandblasting gun on the inner wall of the pipeline can achieve the desired cleanliness at the same time as the surface to be cleaned and a certain degree of roughness, and improve the adhesion of the coating on the basic surface. No matter how good the coating is, it can not adhere to the surface of the workpiece without surface treatment for a long time. The role of surface pretreatment is to clean the surface and create the roughness required to "lock" the coating on the surface. After the sandblasted workpiece surface is coated with an industrial coating with good performance, the coating life can be more than 3.5 times longer than the coating of the same quality on the surface treated by other methods.
Pipeline inner wall sandblasting gun workpiece surface cleaning scale, residual salt, residual oil, etc. after heat treatment; oxide scale, molding sand, etc. of black (non-ferrous) castings; oxide scale, molding sand, etc. of precision castings without margin; machining Residues, micro-burrs, etc .; scales and slag of weldments; scales and rust layers of cold and hot rolled steel plates (profiles); mold release agents and deposits for various mold cavities; ceramics Sintering residues on the surface of components; flashing of plastic molded parts; radioactive elements on the surface of objects; bridges, hydropower station sluices, ships, buildings; rubber coatings for airport runways;
Sandblasting gun equipment on the inner wall of pipes has been widely used in many fields such as machinery manufacturing, instrumentation, medical equipment, electronic appliances, textile machinery, printing and dyeing machinery, ceramics, crafts, machinery repair, and so on. Sand blasting equipment, as a conventional sand processing equipment, has been continuously developed, improved and perfected. It has a unique processing mechanism and a wide range of processing and application scopes. Sand blasting equipment is increasingly favored in today's surface treatment industry.
