An explosive manager makes an annual salary of R550.000 in South Africa. However, this wage may differ according on the employer, experience, and credentials. Some explosive managers may make up to R900,000 annually, while others may only make R300,000.
One can question the cost of sandblasting a terraced house in addition to the wage of an explosive manager. In South Africa, the price of sandblasting a terraced house varies according to the size of the property, the type of surface that needs to be blasted, and the kind of abrasive media employed. Sandblasting a terraced house typically costs between R15,000 and R30,000.
The answer to the query of whether sandblasting sand can be recycled is in the affirmative. When properly cleaned and screened, sandblasting sand can be used repeatedly. However, with time, trash and other items can contaminate sandblasting sand, decreasing its efficacy. Sandblasting sand should therefore be properly maintained and changed as needed.
Yes, metal is removed during sandblasting, addressing the question of whether it does so. Rust, paint, and other coatings can be removed from metal surfaces by sandblasting. Sandblasting, however, can damage or distort fragile or thin metal surfaces. Other techniques, like soda blasting or chemical stripping, may be more appropriate in such circumstances.
The question of whether soda blasting is superior to sandblasting can also be raised. The specific application will determine the response to this query. Baking soda is used as the abrasive medium in soda blasting, a milder substitute for sandblasting. It successfully eliminates coatings and impurities from fragile surfaces like wood and fiberglass. On metal surfaces, it is less efficient at removing severe rust and corrosion. The decision between soda blasting and sandblasting will ultimately be based on the particular requirements of the project.
In conclusion, the average yearly salary for explosive managers in South Africa is R550,000. Sandblasting a terraced house can cost anywhere between R15,000 and R30,000, and if maintained properly, blasting sand can be recycled. Metal can be removed with sandblasting, although other techniques could be better suited for sensitive surfaces. Finally, the particular requirements of the project will determine whether soda blasting or sandblasting is best.
