Résumé : |
There are important criteria to consider when choosing a surface preparation method along with ways to reduce costs associated with this process. When discussing air-powered abrasive blasting, technologies and industry best practices are often overlooked or circumvented in the name of tradition or cost savings, but the results of these choices can be detrimental. This article focuses on steps to maintain or increase production and departmental profits. |

- Improving and maintaining proper nozzle pressure
- Use and testing of blas nozzles
- Selection of blast hoses
- Selecting the correct abrasive for a project
- Fig. 1 : A hypodermic needle-style nozzle pressure gauge kit
- Fig. 2 : Two pressure gauge kits are recommended — one to test the air pressure going into your blast pot and one to test the air pressure coming out
- Fig. 3 : A Venturi-style abrasive blasting nozzle works like a jet engine. Air is compressed rapidly in a cone, then passes through a small orifice and then expands at a more gradual rate than it compressed
- Fig. 4 : A nozzle size analyzer gauge is most frequently used to measure the diameter of a blasting nozzle
- Fig. 5 : Having optimized nozzle pressure is of critical importance
- Fig. 6 : When used correctly, an abrasive that costs more per pound can yield better overall results
