How white aluminum oxide sandblasting works
white aluminum oxide is one of the more commonly used abrasives on the market. Its main chemical component is AL203. According to the content of alumina powder, it can be divided into first-class, second-class and other grades. In recent years, white aluminum oxide tools have become semi-hard and brittle materials. The promotion of precision and precision grinding processing, then, what is the working principle of white aluminum oxide sandblasting?
white aluminum oxide sandblasting abrasive can achieve the required cleanliness and a certain roughness on the surface to be cleaned at the same time, and improve the adhesion of the coating on the basic surface. No matter how good the paint is, it cannot adhere well to the surface of the workpiece without surface treatment for a long time. The purpose of surface pretreatment is to clean the surface and create the roughness on the surface required to “lock” the coating. After the surface of the sandblasted workpiece is coated with an industrial coating with good performance, the coating life can be more than 3.5 times longer than that of the same quality coating on the surface treated by other methods. Another advantage of sandblasting is that the surface roughness can be determined in advance according to the requirements and can be easily achieved during the cleaning process.
