GARNET MICROPOWDER

What is garnet micropowder

Garnet micropowder is a micron-sized natural abrasive. It is based on the natural characteristics of iron aluminum garnet, such as high hardness, high density, good toughness, acid and alkali resistance, and is produced through advanced process control.

According to hardness, it can be divided into ordinary micropowder abrasives and super hard micropowder abrasives. Among them, ordinary micropowder abrasives include three series: corundum(white corundum and brown corundum), silicon carbide and natural abrasives. Garnet micropowder abrasives belong to natural abrasives among ordinary abrasives.

Garnet micropowder characteristics

Garnet micropowder is selected from the hardest almandine rock ore. It is dark red in color, has high hardness, high density, good toughness, and is rich in sharp corners and sharp edges. The processed fine-grained powder is particularly suitable for grinding semiconductors and fluorescent screens in the electronics industry, and lenses and lenses in the optical industry. It is also an ideal material for sandblasting and polishing, making paper pulp grinding wheels and high-precision grinding wheels and emery cloths; in addition, it has good effects on the processing of printing plates, glass products, leather, aggregates, stones, plastics, and electroplating layers.

1. With a hardness of 7.5-8.0 and a density of 4.2g/cm³, it is broken 4 times during the processing process to generate more sharp corners and edges. The sandblasting area is large per unit time, the sand consumption per unit area is small, and the sandblasting cost is low.
2. Thanks to the excellent toughness and low brittleness of almandine, the crushing rate is low during the sandblasting process. It can be recycled 5-10 times depending on the application occasion, further reducing the customer’s use cost.
3. After 6 water washings during the production process, the dust content is extremely low. At the same time, due to the high specific gravity and fast settling speed of garnet sandblasting abrasive, there is less dust during the sandblasting process and the working environment is excellent.
4. The particle size distribution is reasonable, the dust is small, the soluble salt content and conductivity are extremely low, and it does not contain harmful components such as free silicon and heavy metals. It complies with ISO 11126, ISO 11127, SSPC AB-1 and other specifications. It can meet the most stringent industrial and military technical requirements. It is an economical and effective product to replace quartz sand, slag, steel sand and steel shot.

Exact applications

Garnet micropowder is a kind of natural abrasive. In industrial processing, when the processing volume of the workpiece is large and the processing efficiency is required to be improved without pursuing surface quality, a coarser particle size can be selected; on the contrary, in the fields of high-precision cutting, grinding and polishing of precision materials, fine sandblasting, etc., garnet micropowder must be used.

1. Grinding and polishing of precision materials, such as: TV screens, optical components, semiconductors and other special glass products, etc.
2. High-precision water jet cutting, such as glass, plastic, composite materials, fabrics, ceramics, aluminum and ultra-thin alloys.
3. Fine sandblasting cleaning, such as wall graffiti, stone/brick/wood of ancient buildings, valves, gauges, molds, precision devices, etc. of equipment, can remove coatings without generating heat to affect the metal surface.
4. Picture etching, such as glass frosting, galvanized coating, stainless steel, aluminum, alloy, fiberglass, denim, etc.
5. Deburring and polishing, such as masonry, castings, plastics, optical glass components, etc.;
6. Cleaning the outer and inner walls of pipes, fiberglass topcoat, etc., and other cleaning with a roughness of less than 10 microns.
7. Additives for anti-slip materials, oil fume cleaning, cosmetics, paint, rubber, etc. with wear-resistant properties.
