Application of Brown Corundum in Sandblasting
Brown corundum is also named brown fused alumina,brown aluminum oxide,brown electrocorundum etc,main raw material is bauxite.
Brown corundum is widely used in the field of sandblasting, mainly for cleaning, polishing and rust removal of metal, glass, ceramic and other surfaces. Brown corundum sandblasting has the advantages of high hardness, good wear resistance and less dust, which makes it perform well in surface treatment.
Specific application of brown corundum in sandblasting
Metal surface treatment: Brown corundum sandblasting can be used for cleaning, rust removal and polishing of metal surfaces, such as sandblasting of cookware, tableware and pots. The commonly used brown corundum sandblasting particles are 40-60 mesh. After treatment, the surface is smooth and uniform, which can improve the spraying effect and adhesion of the coating.
Glass surface treatment: In glass surface treatment, brown corundum sandblasting can be used for cleaning, polishing and sandblasting pattern production. The commonly used particles are 80-120 mesh. After treatment, the surface is smooth, delicate and uniform, and different sand painting effects and patterns can be produced.
Ceramic surface treatment: Brown corundum sandblasting can also be used for cleaning, polishing and sandblasting pattern production of ceramic surfaces. The surface is smooth, delicate and uniform after treatment, which is suitable for making different patterns and letter patterns.
Advantages of brown corundum in sandblasting
Superior physical properties : The hardness of brown corundum reaches level 9, second only to diamond, and it is wear-resistant and corrosion-resistant, suitable for removing stubborn stains and oxide layers. Its high density and good toughness make it not easy to break during the blasting process, maintaining stable cutting ability.
Environmental protection and safety : Brown corundum is non-toxic and harmless, does not contain free silicon and other harmful substances that cause silicosis, has less dust, reduces environmental pollution and the risk of operators inhaling dust .
High efficiency and energy saving : Brown corundum particles are sharp and can quickly hit the surface of objects under a certain pressure, effectively remove stains and oxide layers, and have low loss, usually saving 1/3 of conventional abrasives.
Reusable : Brown corundum is not easy to break during the sandblasting process, can be reused many times, and reduces costs .
Future development trend of brown corundum in sandblasting
With the advancement of industrial technology, the application of brown corundum in sandblasting will be more extensive. Its high efficiency, environmental protection and durability make it one of the important materials for surface treatment in the future. With the improvement of environmental protection requirements, the environmental protection characteristics of brown corundum will make it be used in more fields.
