How to achieve the ideal effect during white corundum sandblasting?
The principle of white corundum sandblasting seems simple, but every step is very critical and necessary. If the object surface is directly sandblasted instead of dusted first, the adhesion life of the object surface will be greatly reduced, making it difficult to achieve ideal application predictions.
White corundum sandblasting can make the surface to be cleaned achieve the required cleanliness and surface roughness at the same time, and improve the adhesion of the coating to the substrate. No matter how good the coating is, if it is not treated for a long time, the time it can adhere to the surface of the workpiece will be reduced.
In the white corundum sandblasting effect, the ideal effect of surface pretreatment is to clean the surface and convert the surface layer into the roughness required for the coating. After the surface of sandblasted steel parts is coated with an industrial coating with good performance, the service life of the coating with the same surface quality treated by other methods can be much longer than that of the same quality coating treated by other methods.
Another advantage of sandblasting is that workpiece surfaces that are not smooth can be sanded. In short, the purpose of sandblasting is to polish rough surfaces, but in the early stages, the rough surfaces must be cleaned and then sandblasted.
