The working principle of the wet sandblasting machine: It uses sandblasting abrasive (such as brown corundum, glass beads, etc.) and liquid (water) as the medium, and uses compressed air (air compressor) as the power to spray the surface of solid workpieces. Sand machine.
Features of this machine
①The body is made of FRP materials, which is strong and durable and will not corrode.
②Using a new type of non-charged air control switch, simultaneously controlling the sand pump and compressed air, the operation is simple, safe and reliable;
③The design of the sand pump is reasonable, and the stirring is even, so that the surface of the blasted product is even and beautiful, easy to start, long service life, and convenient for maintenance.
④New and novel design, suitable for sandblasting of small and medium-sized precision workpieces.
⑤The parts are imported from well-known brands. Safe and reliable, with few wearing parts.
⑥It is recommended to use finer glass beads and various finer brown corundum, etc.!
The scope of application of this machine
①Suitable for liquid sandblasting
②Suitable for single and small batch sandblasting of small and medium-sized parts
③Clean oxide scale on the surface of heat-treated parts, welded parts, castings, forgings, etc., and the cleaning quality can reach Sa3 level
④Clean up microburrs and surface residues of machined parts
⑤The surface pretreatment processing before spraying and plating of the workpiece can obtain an active surface and improve the adhesion of the sprayed plating layer
⑥ Finishing processing of parts with high precision, small roughness Ra value, and complex shapes that are difficult to complete by other processing methods
⑦Glass surface printing and carving;
⑧Can increase or decrease the roughness Ra value of the workpiece surface within a certain range
⑨Change the stress state of the workpiece surface, which can improve the wear resistance and fatigue strength of the parts
⑩Improve the lubrication conditions of the sports matching parts and reduce the motion noise of the sports matching parts; it can also be used for the refurbishment of old parts.
The main purpose
--Used for surface cleaning of parts, as well as pre-treatment of coating and flaw detection processes. It can clean oxide scale, residual salt, sand, oil stain, rust, carbon deposit, mold release agent of heat-treated parts, welded parts, castings, forgings, etc. , Welding slag stains, paint film, plating and other contaminants, the cleaning quality can reach Sa3 level, while the active surface can be obtained, and the adhesion of coating and plating can be improved.
--Used to clean up the tiny burrs and surface residues of machined parts.
It is used for the finishing of aluminum castings and stainless steel parts to obtain a matte surface and a diffuse reflection surface; it can be used for printing and engraving decorative surface patterns. The effect of light decoration processing is more delicate and beautiful than dry decoration, which improves product quality.
--Used for finishing processing of parts with high precision, small roughness Ra value, and complex shapes that are difficult to complete by other processing methods.
--Used to improve the physical and mechanical properties of the surface of the workpiece, such as changing the surface stress state to increase the fatigue strength; improving the surface lubrication state of the mating part and the movement conditions of the friction pair, and reducing the operating noise.
--Used to refurbish old parts.
--It is used for mold cleaning, does not damage the surface of the mold, and ensures the accuracy of the mold.
