The various advantages of dry ice blasting have been deeply rooted in the hearts of the people, but in the process of dry ice blasting services, there will also be various problems, and many people will also have questions. We will answer the frequently asked questions and Fengli Dry Ice for you.

1. Will dry ice blasting cause impact dents on the surface of the workpiece?

Dry ice blasting is similar to the sandblasting process. Dry ice particles are sprayed onto the surface of the workpiece through compressed air, which will have a certain impact on the surface of the workpiece. However, the dry ice cleaning process does not rely on the abrasive action of dry ice particles and the surface of the workpiece to remove stains, but Quickly freeze the stains on the workpiece, the hardness of the dry ice particles is only 2MOHS, even if the dry ice particles directly hit the surface of the workpiece, they will be crushed immediately without damaging the surface of the workpiece.

For workpieces with very low surface hardness, "snowflake dry ice" can be used as raw material to spray the surface of the workpiece. The main factor that damages the workpiece is the wind pressure, so for fragile parts, the sample test should be carried out first, and then cleaned after setting the appropriate wind pressure.

2. Whereabouts of the removal after dry ice blasting

The direction of the object to be removed by dry ice blasting causes the object to be cleaned to freeze rapidly, forming cracks. When the dry ice expands in the crack, the instant blast makes the object to be cleaned into particles, which are peeled off and adhered with the compressed air blown away. objects and diffuse in the air. Of course, after cleaning, if there are no other measures, these particles diffused in the air will settle on the cleaned site ground like dust, and the dust can be removed by vacuuming.

Under certain conditions, some oil stains or water stains may be scattered on the site. This is due to the presence of some floating residual oil or residual water in the cleaned workpiece. These residual oil or residual water are not attached to the surface of the workpiece but is free. In actual operation, the residual oil in the workpiece should be sucked off with a cloth before cleaning the workpiece with dry ice.
