Characteristics and application of garnet flour
Garnet flour is a natural abrasive of micron grade. It is based on the natural characteristics of ferroaluminum garnet, such as high hardness, high density, good toughness, acid and alkali resistance, and is produced through advanced process control.
Micro-powder abrasive refers to abrasive with a particle size less than 63μm. Its classification method and product requirements are different from the classification method of conventional fine powders. It requires the separation of mixed particle size materials into a series of narrow particle size products with uniform particle size to meet different use requirements. According to its properties and uses, it can be divided into ordinary micro-powder abrasives and super-hard micro-powder abrasives. Among them, ordinary micro-powder abrasives can be divided into three series: corundum, silicon carbide and natural abrasives. Garnet flour belong to natural abrasives among ordinary abrasives.
Features and functions: Garnet flour is selected from the ferroaluminum garnet rock ore with the highest hardness. It is dark red in color, has high hardness, high density, good toughness, sharp corners and sharp edges. The processed fine-grained abrasive 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, polishing, making paper pulp grinding wheels, 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. With a hardness of 7.5-8.0 and a density of 4.2g/cm³, it undergoes 4 crushings during the processing process to generate more sharp corners and tough edges. The sandblasting area is large per unit time, the sand consumption per unit area is small, and the sandblasting cost is low. Thanks to the excellent toughness and low brittleness of iron aluminum garnet, 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. After 6 water washings during the production process, the dust content is extremely low. At the same time, due to the large specific gravity of garnet sandblasting abrasives and the fast settling speed, there is less dust during the sandblasting process and the working environment is excellent. It has reasonable particle size distribution, little dust, extremely low soluble salt content and conductivity, does not contain harmful components such as free silicon and heavy metals, complies with ISO 11126, ISO 11127, SSPC AB-1 and other specifications, can meet the most stringent industrial and military technical requirements, and is an economical and effective product to replace quartz sand, slag, steel sand and steel shot.
