How does soda blasting work and what are its advantages?
The sodium bicarbonate used in the blasting process is a larger particle than the baking soda used in the food industry, although it is the same purity. The particles (baking soda) are propelled by compressed air through specialized blasting pots. The blasting pots use air pressure that can be varied from 20psi on soft surfaces to 120psi on harder surfaces. The now pressurized sodium bicarbonate particles remove coatings by the energy released when the particles explode as they contact the surface being cleaned. Sand blasting, on the other hand, removes the coatings by wearing it away (abrasively). This is also the result when the sand hits the base surface being cleaned; the base surface is worn away and damaged. Sodium bicarbonate has a non-abrasive action that allows it to be used on surfaces that the currently popular abrasive media (sand blasting) would damage i.e.: aluminum, stainless steel, brick, stone, glass, fiberglass, wood, plastic, seals, bearings, splines, radiator cores,
