How to choose the sand blasting used in marking cleaning

Abstract: make the surface roughness meet certain requirements, or achieve certain process objectives, or reduce the reflection of the surface frosted surface. RZG dust-free garnet sand blasting abrasive (NATURAL emery) is generally used.

In the marking cleaning, ordinary steel is usually derusted by sand blasting, which can remove rust, oxide skin and other sundries. Before pickling and passivation, stainless steel will also be sand blasted to remove possible oil stains on the surface, so that the surface roughness can meet certain requirements, or achieve certain process objectives or reduce the reflection of the surface frosted surface. RZG dust-free garnet sand blasting abrasive (NATURAL emery) is generally used. RZG dust-free garnet sand is a kind of high-grade natural non-metallic sandblasting abrasive. It is selected from high-quality iron aluminum garnet rock and ore. It has high hardness, high density and good toughness. It has sharp corners and sharp edge toughness. RZG dust-free pomegranate sand processed according to the highest quality standard has reasonable particle size distribution and less dust. The content and conductivity of soluble salt (chloride) are very low, free silicon, heavy metals and other harmful components are not contained, which conforms to iso11126 Iso11127.pspc and other specifications meet the most stringent industrial and military technical requirements. RZG dust-free pomegranate sand can go deep into holes and uneven parts for cleaning, and completely remove scale, rust, soluble salt and other dirt.
