If you think about the name «sandblasting», then you can easily understand that we are talking about something related to the sand and the jet that delivers it. And indeed it is. Sandblasting is used for grinding or cleaning a dirty surface with the smallest stones — an abrasive. In turn, a sandblaster is a device that allows such grinding. But where does it apply? And who might need?
When a sandblaster is required
A sandblaster is an equipment into which an abrasive material is poured. Then, under high pressure, the substance is taken and supplied to the surface. The feed rate is so high that the surface is quickly cleaned of debris, dust, dirt, rust, and also degreased.
Sandblasting can be used with almost any material — glass, metal, stone. Therefore, it is used to prepare surfaces for painting and final plaster..
Types of sandblasting
Sandblasting machines are quite powerful equipment. They are divided into several types according to the type of device:
pressure cleaning. This is a common variant that was used in the earliest designs of sandblasting machines. A mixture of sand is supplied to the surface to be cleaned with a jet of air under very high pressure and removes all impurities;
wet sand cleaning. In this type of equipment, sand is mixed with water. This does not affect the quality of cleaning, but the process itself becomes safer and faster due to the absence of dust;
fiery cleansing. This is the most powerful way to use sand to clean surfaces. It is based on the supply of an abrasive using a jet stream of another substance. This type of sandblasting is considered the most effective, but expensive..
The sandblaster is an irreplaceable assistant in construction and large-scale repairs. It reduces the likelihood that paint coatings applied to the surface will lose their original appearance in the future. But despite the fact that today sandblasting equipment can be purchased relatively inexpensively, it is not always necessary. Mostly sandblasting is used on really large surfaces. For household repairs, it is quite possible to limit yourself to manual grinding methods..
