Garnet Abrasives Safe For Wet & Dry Blasting

Garnet abrasive is most commonly used as a high-performance blast media, for the cleaning of aluminium and fiberglass structures. It is great for both wet and dry sandblasting applications.  Garnet is a industrial gemstone that creates a profile virtually free of dismemberment, which makes it excellent for coating adhesion, as well as applications where low or no transfer of grit into the substrate can be tolerated.

Garnet sand is a common chemical inert nonmetallic mineral in natural environment. Garnet as a kind of natural abrasive, because of its hardness, high specific gravity, chemical properties and durability become the ideal blasting media on the market. It has the characteristics of non-toxic, low dust, no pollution which is often used as a sandblasting abrasive. Common uses have hardware sandblasting and surface cleaning.  As one of the leading garnet abrasive suppliers in north China, our garnet has been well tested by QC, and has particle size analysis, quality assurance.

Garnet for Blasting

Garnet abrasive sand is in the most potential and widely used abrasive field, because it is used in the industries that are closely related to the production, such as ship hull, bridges, pipes, steel structures sandblasting treatment. It has a large sandblasting area per unit time, less sand consumption, and lower sandblasting costs.

Its hardness can reach 8 mohs with long service life, can be cleaned on the metal surface to produce ideal angular rough surface, increase the surface area of the metal, improve the bonding force of the interface, so that the adhesion of the corrosion protection coating and the metal surface is significantly enhanced, so as to improve the bonding performance of the coating and the metal surface.

High density with stronger impact force, can better clean the metal surface. Garnet has sharp edges and corners, reasonable particle size distribution, and less dust. It can effectively go deep into holes and uneven parts for cleaning, and completely remove scale, rust, soluble salt and other dirt.
