Blasting fundamentals: wheel
vs. air blasting
Blasting technology accelerates abrasive materials against workpieces to achieve effects such as cleaning, descaling, deburring, and roughening. While both wheel and air blasting
The air blasting process is a technique offering precision and versatility for handling complex and large components. This guide delves into the air blasting process, outlining its operation, advantages, and applications, and underscores the importance of expert involvement for achieving unparalleled results.
Understanding air blasting process
Air blasting utilizes compressed air to propel abrasive particles against surfaces for various purposes like cleaning, descaling, or preparing for subsequent treatments. Unlike wheelblasting, air blasting offers manual control, making it suitable for intricate, large, or uniquely shaped components. While generally considered less productive due to its manual nature, air blasting shines in delivering unit-specific precision, particularly crucial for complex assemblies and structures such as frames, chassis, and wind turbine components.
Operational variants and their applications
Air blasting can be executed in two primary modes, depending on the application's specific needs:
Pressure mode (overpressure): Ideal for ferrous surface preparation, this mode employs abrasives like steel grit, corundum, cast iron, and stainless steel slag to aggressively clean and profile surfaces. Commonly used in larger cabins, pressure mode maximizes efficiency and effectiveness for robust surface preparation.
Suction mode: Tailored for more delicate or sensitive surfaces, suction mode is gentler, making it suitable for materials like aluminum, stainless steel, and even glass or carbon. Utilizing finer abrasives, this method is predominantly applied in smaller cabins where precision and surface integrity are paramount.
The necessity of dedicated air compressed networks
A dedicated air compressed network is vital for the air blasting process, ensuring consistent pressure and flow, which are crucial for achieving uniform treatment results. This setup must be carefully calibrated and maintained to accommodate the varying demands of different abrasives and support materials.
Choosing the right abrasives for air blasting
The selection of abrasives in air blasting is diverse, catering to different substrates and desired finishes:
Angular abrasives (GH/GL): Used for aggressive cleaning and surface preparation, these abrasives are suitable for creating a profile that enhances coating adhesion.
Steel Abrasives
Stainless steel grit (Stelux CG): Preferred for applications demanding cleanliness and minimal ferrous contamination, especially in industries like food processing or medical equipment manufacturing.
Stainless Steel Abrasives
Specialty media for shot peening: In applications requiring surface stress relief or hardening, round abrasives like steel shot or conditioned cut wire are employed to deliver consistent peening intensity.
