Characteristics of shot blasting in Dalian sand blasting

Shot blasting is generally used for regular shaped workpieces. Several polishing heads are up, down, left and right together, with high efficiency and little pollution. Shot blasting and sand blasting are widely used in the repair and shipbuilding industry. However, whether shot blasting or sand blasting, compressed air is used. Of course, it is not shot blasting that requires a high-speed rotating impeller. In the repair and shipbuilding industry, shot blasting (small steel shot) is generally used in steel plate pretreatment (rust removal before coating); Sand blasting (mineral sand used in repair and shipbuilding) is mostly used in formed ships or sections to remove the old paint and rust on the steel plate and repaint it. In the repair and shipbuilding industry, the main function of shot blasting and sand blasting is to increase the adhesion of steel plate coating paint.

In fact, the casting cleaning is not just shot blasting. For large parts, the drum sand cleaning is generally carried out first, that is, the riser of the casting is cut off and then rolled in the drum. The parts collide with each other in the drum, and most of the sand on the surface is cleaned first, and then shot blasting or shot blasting is carried out.

Characteristics of Shot Peening:

1. Great flexibility in cleaning. It is easy to clean the internal and external surfaces of complex workpieces and the inner wall of pipe fittings; And it is not limited by the site. It can be moved to the vicinity of oversized workpieces for cleaning.

2. The equipment has the advantages of simple structure, less investment, less vulnerable parts and low maintenance cost.

3. High energy consumption requires high-power air compressor station

4. The cleaned surface is prone to moisture and embroidery.

5. Low cleaning efficiency, many operators and high labor intensity.
