Dust-free sand is yellow, brown, spherical, with an alumina content of 85%, and the pressure is between 52Mpa-65Mpa, and the hardness is moderate. Clean and clean. Not easily broken. It can be used repeatedly. The sandblasting effect is good. Dust-less sand is a highly efficient product in sandblasting. It is widely used in cleaning and a unique abrasive for metal surface strengthening and used primarily for sandblasting equipment, glass sandblasting effect.

Features of dust-free emery sand:

High hardness, easy flow, no dust, strong abrasion resistance, long-lasting resistance, and minimal friction between each other. This kind of spherical structure product will not have particles embedded, pollute the workpiece or cause further damage during use, thereby achieving environmental protection. Using different sizes of abrasives and other operating parameters, shot peening will achieve different gloss levels on the workpiece’s surface to achieve the effect!

Application of dust-free emery sand:

Dust-free emery sand mainly removes mold burrs, precision polishing repair, polishes and cleans the glass wool layer, and can also polish the large finished equipment (pearl) for surface finish treatment, removes the product surface oxide layer and surface layer rust, insulation trace treatment, and other properties Use these properties to achieve an environmentally friendly effect.

1. Sandblasted glass, steel. Steel Pipe. Matte surface treatment of steel structure stainless steel products. Sandblasting and rust removal before spraying.
2. Used for cleaning various molds
3. It can remove the tensile stress of various mechanical parts and increase the fatigue life
4. For semiconductor devices, the plastic encapsulation tube is cleaned before tinning to remove edge thorns
5. Shot peening and finishing of medical equipment, textile machinery, and various hardware products
6. Cleaning and removing burr residues of various metal pipes and non-ferrous metal precision castings.

Product characteristics of dust-free emery sand:

1. Both soft and hard—the raw materials produced with high-quality materials have specific mechanical strength, the content of AL2O3 is greater than or equal to 68%, the hardness can reach 6-7 Mohs, and it has sufficient flexibility, which can be used repeatedly for several times, and it is not easy to break. , The sprayed device has the same effect, which is more than three times longer than that of ordinary emery.
2. Good uniformity-the rounding rate is greater than or equal to 80%, and the particle size is uniform. After spraying, the sandblasting device’s vertical coefficient can be kept uniform, and it is not easy to leave watermarks.
