Puhallusmenetelmä

Puhallusmenetelmä, often translated as "blowing method" or "air blast method," is a technique primarily used in industrial settings for cleaning and surface preparation. It involves directing a high-pressure stream of air, or sometimes a mixture of air and abrasive particles, at a surface. This forceful application of air can dislodge loose debris, dust, and contaminants from intricate or difficult-to-reach areas.

The core principle of puhallusmenetelmä relies on the kinetic energy of the moving air. When directed at a surface, the air stream exerts pressure, pushing away unwanted material. For more aggressive cleaning or surface profiling, fine abrasive media such as sand, glass beads, or other inert particles can be introduced into the air stream. These particles then impact the surface, acting like tiny hammers to remove stubborn residues, rust, paint, or scale.

This method finds applications in various industries, including manufacturing, automotive repair, construction, and electronics. It is frequently employed for cleaning molds, castings, engine parts, circuit boards, and structural elements before painting, welding, or further processing. The choice of air pressure, nozzle type, and abrasive medium (if used) is determined by the specific cleaning requirements and the sensitivity of the material being treated. Puhallusmenetelmä offers a non-contact or minimally abrasive method for effective cleaning and surface preparation, contributing to improved product quality and longevity.
