Sandblasting Process, Theory & Facts

Sometimes industry imitates wild nature.  Sandblasting is very similar to a natural process called erosion.  According to Wikipedia, Erosion is the process of weathering and transport of solids (sediment, soil, rock and other particles) in the natural environment or their source and deposits them elsewhere. But in the wild nature the process takes millions of years to do the job. On the other hand industrial sandblasting erodes the surfaces of many materials to achieve a proper finish.

Benjamin Chew Tilghman invented and patented the first sandblasting machine in 1870. He formulated this concept from observing rocks that had smooth surfaces from windblown sand. His machine harnessed this power to use as a tool in the labor-intensive job of removing painted and rusted surfaces from the underlying material.

What are the main benefits of the Sandblasting Process?

  1. It saves time, especially if you compares it to a manual process.
  2. Painted surfaces are evenly removed with ease.
  3. Due the nature of the sandblasting process you can access to hard to reach places.

The main caution to think about this technique is that breathing the dust created by the sandblast process is very harmful. This is the reason you must always use use protective accessories like sandblaster gloves, protective glasses and sandblasting masks. It is extremely important to follow the mandatory guidelines of OSHA; wear full protective gear and respirators when using this process.

  1. PREGNTA : ¿ El impacto del grano de arena sobre el metal produce ionización en el mismo , luego estas particulas polulan en un radio de 5 Km. a la redonda , el que los respira corre el riesgo de que las particulas se adhieran a los albeolos pulmonares, produciendose una especie de Cilicosis, por esto este proceso esta limitado por noemas dadas en paises Industrializados . Cuales son estas normas ?.
