In the Sandblasting process of stainless steel surface treatment, the spray angle is a key factor and has a significant impact on the uniformity of treatment.
The spray angle determines the way and position of the sand particles impacting the stainless steel surface. When the spray angle is more vertical, the sand particles directly hit the surface with a large impact force, which can quickly remove impurities and oxide layers on the surface. However, in this case, it is easy to form local deep pits at the impact point, resulting in uneven surface roughness.
On the contrary, if the spray angle is too inclined, the contact area between the sand particles and the surface increases, the impact force is relatively dispersed, and the effect of removing impurities may be weakened. At the same time, due to the increase in the sliding distance of the sand particles on the surface, it is easy to cause over-treatment of some areas and under-treatment of other areas.
In addition, the spray angle will also affect the distribution of sand particles on the stainless steel surface. An unreasonable angle may cause the sand particles to concentrate in certain areas and form accumulation, while other areas lack effective impact of sand particles. This greatly reduces the uniformity of surface treatment. For example, when using high-pressure Sandblasting equipment, if the spray angle is too small, excessive cutting action may occur locally, destroying the flatness of the stainless steel surface. When the angle is too large, the sand grains may not be able to effectively remove stubborn stains or oxide layers.
In order to achieve uniform surface treatment, it is necessary to comprehensively consider factors such as the type of Sandblasting equipment, the characteristics of the sand grains, and the shape of the stainless steel workpiece to determine the optimal spray angle. In actual operation, the most suitable angle range can be found through multiple tests and adjustments. In addition, automated Sandblasting equipment can better control the stability and consistency of the spray angle, thereby improving the uniformity and quality reliability of stainless steel surface treatment.
In short, the spray angle plays a vital role in the uniformity of stainless steel surface treatment during the Sandblasting process. Understanding and mastering its influencing mechanism is of great significance for optimizing the Sandblasting process and improving the surface treatment effect of stainless steel.
