2. Što je pjeskarenje perlama?

Definicija

Bead blasting is a surface finishing technique that uses fine abrasive media—typically glass or ceramic beads—to modify material surfaces.

By leveraging compressed air, these beads are propelled at high speeds toward the part’s surface, effectively removing contaminants, smoothing rough areas,

or creating a textured finish without damaging the underlying material.

Kako radi

In the bead blasting process, stroj koristi komprimirani zrak za usmjeravanje sitnih kuglica na površinu dijela.

Kuglice utječu na materijal, učinkovito čišćenje i zaglađivanje površine uklanjanjem nečistoća poput prljavštine, hrđa, ulje, i stari premazi.

Pjeskarenje se također može koristiti za stvaranje jednolične teksture, bilo mat ili saten, ovisno o mediju i parametrima miniranja.
