Main usage of plastic media blasting
First we much check what media blasting actually is before we can check what it’s main usage is. Plastic media blasting is blasting process which uses dry abrasive. It is designed to replace chemical paint from surface. Plastic media blasting is therefore mainly used on aircrafts to clear their surface of paint.
Since plastic media blasting must be performed in a closed ventilated area which hangars where airplanes are is. Plastic media blasting is also a lot more cost effective then other types of stripping paint from airplanes. Although plastic medis blasting generates up to 50% less hazardous materials it is still dangerous. Safety precautions must therefore be made before you start with this kind of operation.
Plastic media blasting equipment does have it’s problem. Equipment used for it is not compatible with regular sandblasting equipment so initial investment costs can be quite high. But in the end, you will have nice profit with using this method.
Media blasting equipment
There are different media blasting equipment we use. Most commonly used is soda blasting. Soda blasting is nothing else then media blasting equipment that uses sodium bicarbonate as media.
We also know other media blasting equipment. Apart soda blasting we use other media also, sand is most widely used because it’s easiest to get. We also know other media blasting equipment, aluminum oxide, corn cob, glass grit, steel grid, steel shot and many other.
Soda blasting is used most because sodium bicarbonate is one of best media blasting equipment. Sodium is not that hazardous to workers, it does not damage glass, chrome or fiberglass which is why it can be used more or less everywhere and it’s water soluable. The final effect is same as using sand as a media but the surface is a lot less damaged if you use sodium bicarbonate.
