HLK-W Series High-Efficiency Liquid Jet Sandblasting Machine Application Scope: 1. Used for surface cleaning of parts and as a pretreatment for coating and flaw detection processes, capable of removing oxidation scales, residual salt, molding sand, oil stains, rust, carbon deposits, release agents, slag, stains, paint films, coatings, etc., achieving a cleaning quality up to Sa3 level; 2. Used for surface finishing of parts to achieve matte or diffused surfaces; suitable for spray painting and engraving of decorative surface patterns. The finishing effect is finer and more aesthetically pleasing than dry finishing; 3. Used to alter the roughness of part surfaces, either increasing or decreasing the Ra value; 4. Used to improve the physical and mechanical properties of part surfaces, enhancing surface stress conditions, improving fatigue resistance; improving surface electrode potential, enhancing corrosion resistance; improving surface lubricity, improving operating conditions and reducing operating noise; increasing the microsurface area, enhancing the adhesion of the coating layer.
