Tech/Engineering - Materials (Plastics, Ceramics, etc.) / Abrasive blasting
English term or phrase: breakdown rate
Caring for your operators is of chief importance when it comes to abrasive blasting, especially with mineral abrasives as the fine nature of the materials used and high breakdown rate can cause significant damage if inhaled by employees.

Beh, la degradazione può anche essere fisica o meccanica.
In alternativa potresti usare il termine "disgregazione"?

Asker: Grazie, lo avevo visto ma mi sembra sia applicabile a sostanze chimiche. Qui si tratat di un breakdown meccanico, quando i granelli della sabbia usata per il processo di sabbiatura colpiscono la superficie trattata e si "disintegrano" per l'impatto ad alta pressione, non tanto si degradano. Vediamo...

(velocità di) erosione


Explanation:
A temperature sotto zero il policarbonato diventa fragile e la superficie del granulato si erode a causa degli urti e delle sollecitazioni all'interno del ciclo di sbavatura.
Questa erosione (breakdown rate) aumenta mano a mano che la temperatura si abbassa, fino a che il granulo si frantuma durante l'impatto.
https://www.ferroplast.com/dieblast.htm

nella pagina EN:
At sub zero temperatures polycarbonate resin becomes brittle and the surface of the granulate erodes due to impact stresses within the blasting cycle.

This erosion or breakdown rate increases as the temperature is lowered until the granulate fractures on impact. Standard polycarbonate resins disintegrate

Asker: Grazie, si parla di erosione della superficie trattata. HO trovato nel frattempo, si dice frantumazione!
