Q&A

Q1: How does an American sandblaster work?

A1: In simple terms, a sandblaster works by compressing air. Then, the machine uses the air pressure to propel small particles of sand or any other media in the blasting chamber. Finally, the propelled particles strike and clean the target object's surface.

Q2: What are the different types of sandblasters?

A2: There are four main types of sandblasters: pressure sandblaster, suction sandblaster, siphon sandblaster, and dry ice blaster. The pressure sandblaster works by air pressuring the blasting media. In a suction sandblaster, the media falls into the air pipeline by gravity. The siphon sandblaster works almost like a suction sandblaster, but it works under the principle of air pressure. Finally, a dry ice machine blasts dry ice pellets to strip surfaces and get rid of contaminants.

Q3: What is the purpose of sandblasting?

A3: The main purpose of sandblasting is to abrade, clean, or coat an object's surface. Sandblasting is widely used in the construction industry for surface preparation before painting or applying any other coating. It is also used in the automotive industry for the same purpose. Additionally, sandblasting has engraving and polishing applications in the glass industry.

Q4: Why is it called sandblasting?

A4: The name is derived from the fact that the process involves using propelled particles like sand and other materials, such as steel grit and aluminum oxide, as blasting media.
