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 required cleanliness of the surface to be cleaned at the same time and a certain roughness on the surface, 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 produce 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 same quality coating on the surface treated by other methods.
Pipeline inner wall sandblasting gun workpiece surface cleaning scales, residual salts, residual oil, etc. after heat treatment; oxide scales, molding sand, etc. of black (non-ferrous) castings; oxide scales, molding sand, etc. of precision castings with no margin; 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 Sintered 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 on airport runways;
Pipeline sandblasting gun equipment has been widely used in machinery manufacturing, instrumentation, medical equipment, electronics, textile machinery, printing and dyeing machinery, ceramics, handicrafts, machinery repair and many other fields. 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 becoming more and more popular in today's surface treatment industry.
