Technical Field
The invention belongs to the technical field of white corundum testing, and particularly relates to a method for identifying a white corundum reclaimed material.
Background
White corundum, a kind of artificial abrasive, is aluminum oxide (Al)2O3) The content is more than 97.5%, and the product contains small amount of iron oxide, silicon oxide, sodium oxide, etc., and is white. The white corundum has the characteristics of high purity, good self-sharpening property, acid and alkali corrosion resistance, high temperature resistance and stable thermal state performance, and is widely applied. The normal white corundum is expensive and has certain requirements on composition, density, packaging and the like. The white corundum generates a large amount of reclaimed materials after being used, the white corundum cannot be used according to the original purpose because the white corundum loses performance after being used, the white corundum becomes solid waste, if the white corundum is recycled, acid pickling is needed, a large amount of acid is consumed in the process, and great pollution is generated to the environment. For example, the imported white corundum is a waste recycled material, so that not only is an enterprise subjected to economic loss, but also a huge risk of environmental pollution is brought to China, and therefore, the method is very important for identifying the authenticity of the white corundum recycled material.
Currently, there are definite requirements for white corundum products, including type, composition, granularity, magnetism, density, packaging, etc. But the identification method of the reclaimed materials has no standard and easy operation mode.
